2011-01-01

The objectives of the Technology Watch process are to identify emerging, high-impact technologies that augment current ExMC development efforts, and to work with academia, industry, and other government agencies to accelerate the development of medical care and research capabilities for the mitigation of potential health issues that could occur during space exploration missions. The establishment of collaborations with these entities is beneficial to technology development, assessment and/or insertion. Such collaborations also further NASA s goal to provide a safe and healthy environment for human exploration. The Tech Watch project addresses requirements and capabilities identified by knowledge and technology gaps that are derived from a discrete set of medical conditions that are most likely to occur on exploration missions. These gaps are addressed through technology readiness level assessments, market surveys, collaborations and distributed innovation opportunities. Ultimately, these gaps need to be closed with respect to exploration missions, and may be achieved through technology development projects. Information management is a key aspect to this process where Tech Watch related meetings, research articles, collaborations and partnerships are tracked by the HRP s Exploration Medical Capabilities (ExMC) Element. In 2011, ExMC will be introducing the Tech Watch external website and evidence wiki that will provide access to ExMC technology and knowledge gaps, technology needs and requirements documents.

The nitrogen abatement cost in wetlands

International Nuclear Information System (INIS)

Bystroem, Olof

1998-01-01

The costs of abating agricultural nitrogen pollution in wetlands are estimated. By linking costs for construction of wetlands to the denitrification capacity of wetlands, an abatement cost function can be formed. A construction-cost function and a denitrification function for wetlands is estimated empirically. This paper establishes a link between abatement costs and the nitrogen load on wetlands. Since abatement costs fluctuate with nitrogen load, ignoring this link results in incorrect estimates of abatement costs. The results demonstrate that wetlands have the capacity to provide low cost abatement of nitrogen compounds in runoff. For the Kattegatt region in Sweden, marginal abatement costs for wetlands are shown to be lower than costs of land use changing measures, such as extended land under fallow or cultivation of fuel woods, but higher than the marginal costs of reducing nitrogen fertilizer

Marginal abatement cost curves for Heavy Duty Vehicles. Background report

Energy Technology Data Exchange (ETDEWEB)

Schroten, A.; Warringa, G.; Bles, M.

2012-09-15

Cost curves were calculated for CO2 abatement technologies for Heavy Duty Vehicles. These curves were elaborated for eight different vehicle categories (six categories of truck and two subcategories), as well as for an 'average' truck and bus. Given that cost curves depend very much on underlying assumptions, the MACH model (Marginal Abatement Costs of Heavy duty vehicles) was developed. This model allows users to enter their own assumptions with respect to parameters like fuel prices and cost and lifetime of individual technologies, with the model then generating new cost curves for the various vehicle categories. This background report contains a description of the model and a summary of the results of several model runs.

Pricing emission permits in the absence of abatement

International Nuclear Information System (INIS)

Hintermann, Beat

2012-01-01

If emissions are stochastic and firms are unable to control them through abatement, the cap in a permit market may be exceeded, or not be reached. I derive a binary options pricing formula that expresses the permit price as a function of the penalty for noncompliance and the probability of an exceeded cap under the assumption of no abatement. I apply my model to the EU ETS, where the rapid introduction of the market made it difficult for firms to adjust their production technology in time for the first phase. The model fits the data well, implying that the permit price may have been driven by firms hedging against stochastic emissions.

Removal of enzyme inhibitors released during lignocellulose pretreatment is essential for economically feasible biofuel production. We tested bio-abatement to mitigate enzyme inhibitor effects observed in corn stover liquors after pretreatment with either dilute acid or liquid hot water at 10% (w/v) solids. Bio-abatement of liquors was followed by enzymatic hydrolysis of cellulose. To distinguish between inhibitor effects on enzymes and recalcitrance of the substrate, pretreated corn stover solids were removed and replaced with 1% (w/v) Solka Floc. Cellulose conversion in the presence of bio-abated liquors from dilute acid pretreatment was 8.6% (0.1x enzyme) and 16% (1x enzyme) higher than control (non-abated) samples. In the presence of bio-abated liquor from liquid hot water pretreated corn stover, 10% (0.1x enzyme) and 13% (1x enzyme) higher cellulose conversion was obtained compared to control. Bio-abatement yielded improved enzyme hydrolysis in the same range as that obtained using a chemical (overliming) method for mitigating inhibitors. Copyright © 2013 Elsevier Ltd.

2011-01-01

Highlights: → We review the current status of catalytic and non-catalytic VOC abatement based on a vast number of research papers. → The underlying mechanisms of plasma-catalysis for VOC abatement are discussed. → Critical process parameters that determine the influent are discussed and compared. - Abstract: This paper reviews recent achievements and the current status of non-thermal plasma (NTP) technology for the abatement of volatile organic compounds (VOCs). Many reactor configurations have been developed to generate a NTP at atmospheric pressure. Therefore in this review article, the principles of generating NTPs are outlined. Further on, this paper is divided in two equally important parts: plasma-alone and plasma-catalytic systems. Combination of NTP with heterogeneous catalysis has attracted increased attention in order to overcome the weaknesses of plasma-alone systems. An overview is given of the present understanding of the mechanisms involved in plasma-catalytic processes. In both parts (plasma-alone systems and plasma-catalysis), literature on the abatement of VOCs is reviewed in close detail. Special attention is given to the influence of critical process parameters on the removal process.

We theoretically investigate the interaction between endogenous enforcement of intellectual property rights (IPRs) and tax-financed pollution abatement measures. IPRs affect dirty and clean intermediates alike such that higher IPR enforcement may promote the transition to the clean technology, if this technology is productive enough. If the green technology is relatively unproductive, higher IPRs promote the dirty technology while pollution is increasing. As households are due to subsistence ...

PM sources in a highly industrialised area in the process of implementing PM abatement technology. Quantification and evolution.

Cruz Minguillón, María; Querol, Xavier; Alastuey, Andrés; Monfort, Eliseo; Vicente Miró, José

2007-10-01

Principal component analysis (PCA) coupled with a multilinear regression analysis (MLRA) was applied to PM(10) speciation data series (2002-2005) from four sampling sites in a highly industrialised area (ceramic production) in the process of implementing emission abatement technology. Five common factors with similar chemical profiles were identified at all the sites: mineral, regional background (influenced by the industrial estate located on the coast: an oil refinery and a power plant), sea spray, industrial 1 (manufacture and use of glaze components, including frit fusion) and road traffic. The contribution of the regional background differs slightly from site to site. The mineral factor, attributed to the sum of several sources (mainly the ceramic industry, but also with minor contributions from soil resuspension and African dust outbreaks) contributes between 9 and 11 microg m(-3) at all the sites. Source industrial 1 entails an increase in PM(10) levels between 4 and 5 microg m(-3) at the urban sites and 2 microg m(-3) at the suburban background site. However, after 2004, this source contributed less than 2 microg m(-3) at most sites, whereas the remaining sources did not show an upward or downward trend along the study period. This gradual decrease in the contribution of source industrial 1 coincides with the implementation of PM abatement technology in the frit fusion kilns of the area. This relationship enables us to assess the efficiency of the implementation of environmental technologies in terms of their impact on air quality.

Understanding selected trace elements behavior in a coal-fired power plant in Malaysia for assessment of abatement technologies.

Science.gov (United States)

Mokhtar, Mutahharah M; Taib, Rozainee M; Hassim, Mimi H

2014-08-01

The Proposed New Environmental Quality (Clean Air) Regulation 201X (Draft), which replaces the Malaysia Environmental Quality (Clean Air) 1978, specifies limits to additional pollutants from power generation using fossil fuel. The new pollutants include Hg, HCl, and HF with limits of 0.03, 100, and 15 mg/N-m3 at 6% O2, respectively. These pollutants are normally present in very small concentrations (known as trace elements [TEs]), and hence are often neglected in environmental air quality monitoring in Malaysia. Following the enactment of the new regulation, it is now imperative to understand the TEs behavior and to assess the capability of the existing abatement technologies to comply with the new emission limits. This paper presents the comparison of TEs behavior of the most volatile (Hg, Cl, F) and less volatile (As, Be, Cd, Cr, Ni, Se, Pb) elements in subbituminous and bituminous coal and coal combustion products (CCP) (i.e., fly ash and bottom ash) from separate firing of subbituminous and bituminous coal in a coal-fired power plant in Malaysia. The effect of air pollution control devices configuration in removal of TEs was also investigated to evaluate the effectiveness of abatement technologies used in the plant. This study showed that subbituminous and bituminous coals and their CCPs have different TEs behavior. It is speculated that ash content could be a factor for such diverse behavior In addition, the type of coal and the concentrations of TEs in feed coal were to some extent influenced by the emission of TEs in flue gas. The electrostatic precipitator (ESP) and seawater flue gas desulfurization (FGD) used in the studied coal-fired power plant were found effective in removing TEs in particulate and vapor form, respectively, as well as complying with the new specified emission limits. Implications: Coals used by power plants in Peninsular Malaysia come from the same supplier (Tenaga Nasional Berhad Fuel Services), which is a subsidiary of the Malaysia

Coupled Climate-Economy-Biosphere (CoCEB) model - Part 1: Abatement share and investment in low-carbon technologies

Ogutu, K. B. Z.; D'Andrea, F.; Ghil, M.; Nyandwi, C.; Manene, M. M.; Muthama, J. N.

2015-04-01

The Coupled Climate-Economy-Biosphere (CoCEB) model described herein takes an integrated assessment approach to simulating global change. By using an endogenous economic growth module with physical and human capital accumulation, this paper considers the sustainability of economic growth, as economic activity intensifies greenhouse gas emissions that in turn cause economic damage due to climate change. Different types of fossil fuels and different technologies produce different volumes of carbon dioxide in combustion. The shares of different fuels and their future evolution are not known. We assume that the dynamics of hydrocarbon-based energy share and their replacement with renewable energy sources in the global energy balance can be modeled into the 21st century by use of logistic functions. Various climate change mitigation policy measures are considered. While many integrated assessment models treat abatement costs merely as an unproductive loss of income, we consider abatement activities also as an investment in overall energy efficiency of the economy and decrease of overall carbon intensity of the energy system. The paper shows that these efforts help to reduce the volume of industrial carbon dioxide emissions, lower temperature deviations, and lead to positive effects in economic growth.

Full Text Available This paper studies the technological capability in the Brazilian Official Pharmaceutical Laboratories [OPL]. The technological capability analysis could contribute to organization strategies and governmental actions in order to improve OPL basic tasks as well to incorporate new ones, particularly concerning the innovation management. Inspired in Figueiredo (2000, 2003a, 2003b and Figueiredo and Ariffin (2003, a framework was drawn and adapted to pharmaceutical industry characteristics and current sanitary and health legislation. The framework allows to map different dimensions of the technological capability (installations, processes, products, equipments, organizational capability and knowledge management and the level attained by OPL (ordinary or innovating capability. OPL show a good development of ordinary capabilities, particularly in Product and Processes. Concerning the other dimensions, OPL are quite diverse. In general, innovating capabilities are not much developed. In the short term, it was identified a dispersion in the capacitating efforts. Considering their present level and the absorption efforts, good perspectives can be found in Installations, Processes and Organizational Capability. A lower level of efforts in Products and Knowledge Management could undermine these capabilities in the future.

Abatement Technologies for Volatile Organic Compounds in Emissions from Biofuel Driers; Reningsteknik foer organiska aemnen i utslaepp till luft vid biobraensletorkning

Energy Technology Data Exchange (ETDEWEB)

Nielsen, Karin; Ehrstedt, Thomas [Sycon Energikonsult AB, Malmoe (Sweden)

2000-06-01

This report is a part of a program at Vaermeforsk called Drying of Biofuels and deals with abatement technologies for volatile organic compounds (VOC) in biofuel drier emissions. The report gives an account of the amount of organic matter in wood and in drying gases and also of different abatement technologies for VOC. Processes from about 20 contractors are briefly described. The conclusions from this work are that thermal or catalytic oxidizing technologies in connection with regenerative heat recovery seems to be the most suitable technique for this application. Both technologies should give a degree of purification above 95 %. The purification cost for a typical case has been estimated to about 22 SEK per kg removed organic matter in both cases. The investment cost is higher for the catalytic oxidizer (6-20 MSEK for a 60.000 Nm{sup 3} /h catalytic plant compared to 4-6,5 MSEK for a thermal plant) but the fuel cost is lower. Condensation is a usable technique but it suffers from bad degree of purification. By using a wet electrostatic precipitator (WESP) the degree of purification can be enhanced but it will still be lower than for the oxidizers. Adsorption and absorption are not suitable for gases at high temperatures containing several different organic compounds at low concentrations, which is the case in biofuel drying. This means high purification costs and low degree of purification. Other technologies that have been found less suitable are biological purification and membrane technology. World-wide there are a few reference plants based on thermal oxidizing in connection with biofuel drying. Otherwise the experiences are very limited. According to this, tests in pilot plant scale are recommended before investment in a full-scale plant for biofuel driers.

Feasibility study on improving SO/sub 2/ abatement economics through improvements in byproduct utilization. Final report. 2 Volumes

Energy Technology Data Exchange (ETDEWEB)

1984-01-17

This study was undertaken to assess the technical feasibility of improving SO/sub 2/ abatement economics through improvements in byproduct utilization, and to recommend the most appropriate strategy for fostering the development and commericalization of such technology. Existing byproduct technology was reviewed and the potential for new technology assessed. This was done by a literature review and a survey of individuals and organizations actively engaged in this area. The assessment is confined to technical aspects only. This phase of the study concludes that there is a wide range of abatement byproduct technology, at various stages of development, which if appropriately exploited, offers the potential of improving byproduct utility and value, and hence the economics of Canadian SO/sub 2/ abatement. The second phase of this study addresses the problem of the most effective strategy for ensuring the development and commercialization of appropriate byproduct technology. This is based on discussions with individuals and organizations involved in the field, and assessment of the motivation and potential effectiveness of alternative approaches within the context of a diverse Canadian industry, the technology status in Canada and the national need.

Exploring the limits for CO2 emission abatement in the EU power and industry sectors—Awaiting a breakthrough

International Nuclear Information System (INIS)

Rootzén, Johan; Johnsson, Filip

2013-01-01

This study assesses the prospects for presently available abatement technologies to achieve significant reductions in CO 2 emissions from large stationary sources of CO 2 in the EU up to year 2050. The study covers power generation, petroleum refining, iron and steel, and cement production. By simulating capital stock turnover, scenarios that assume future developments in the technology stock, energy intensities, fuel and production mixes, and the resulting CO 2 emissions were generated for each sector. The results confirm that the EU goal for reductions in Greenhouse Gas Emission in the sectors covered by the EU Emission Trading System, i.e., 21% reduction by 2020 as compared to the levels in 2005, is attainable with the abatement measures that are already available. However, despite the optimism regarding the potential for, and implementation of, available abatement strategies within current production processes, our results indicate that the power and industrial sectors will fail to comply with more stringent reduction targets in both the medium term (2030) and long term (2050). Deliberate exclusion from the analysis of mitigation technologies that are still in the early phases of development (e.g., CO 2 capture and storage) provides an indirect measure of the requirements for novel low-carbon technologies and production processes. - Highlights: • Explore the limits for CO 2 emission abatement within current production processes. • Analysis of scenarios for CO 2 emissions from EU power and industrial sectors 2010–2050. • Short-term (2020) emission targets are attainable with available abatement measures. • Fail to comply with more stringent reduction targets in the long term (2050). • Efforts to develop new low-carbon production processes need to be accelerated

NOx Abatement Pilot Plant 90-day test results report

International Nuclear Information System (INIS)

McCray, J.A.; Boardman, R.D.

1991-01-01

High-level radioactive liquid wastes produced during nuclear fuel reprocessing at the Idaho Chemical Processing Plant are calcined in the New Waste Calcining Facility (NWCF) to provide both volume reduction and a more stable waste form. Because a large component of the HLW is nitric acid, high levels of oxides of nitrogen (NO x ) are produced in the process and discharged to the environment via the calciner off-gas. The NO x abatement program is required by the new Fuel Processing Restoration (FPR) project permit to construct to reduce NO x emissions from the NWCF. Extensive research and development has indicated that the selective catalytic reduction (SCR) process is the most promising technology for treating the NWCF off-gas. Pilot plant tests were performed to determine the compatibility of the SCR process with actual NWCF off-gas. Test results indicate that the SCR process is a viable method for abating the NO x from the NWCF off-gas. Reduction efficiencies over 95% can be obtained, with minimal amounts of ammonia slip, provided favorable operating conditions exist. Two reactors operated with series flow will provide optimum reduction capabilities. Typical operation should be performed with a first reactor stage gas space velocity of 20,000 hr -1 and an inlet temperature of 320 degrees C. The first stage exhaust NO x concentration will then dictate the parameter settings for the second stage. Operation should always strive for a peak reactor temperature of 520 degrees C in both reactors, with minimal NH 3 slip from the second reactor. Frequent fluctuations in the NWCF off-gas NO x concentration will require a full-scale reduction facility that is versatile and quick-responding. Sudden changes in NWCF off-gas NO x concentrations will require quick detection and immediate response to avoid reactor bed over-heating and/or excessive ammonia slip

2018-05-10

The pollutant abatement systems are widely applied in the coal-fired power sector and the energy consumption was considered an important part of the auxiliary power. An energy consumption analysis and assessment model of pollutant abatement systems in a power unit was developed based on the dynamic parameters and technology. The energy consumption of pollutant abatement systems in a 1000 MW coal-fired power unit which meet the ultra-low emission limits and the factors of operating parameters including unit load and inlet concentration of pollutants on the operating power were analyzed. The results show that the total power consumption of the pollutant abatement systems accounted for 1.27% of the gross power generation during the monitoring period. The WFGD system consumed 67% of the rate while the SCR and ESP systems consumed 8.9% and 24.1%. The power consumption rate of pollutant abatement systems decreased with the increase of unit load and increased with the increase of the inlet concentration of pollutants. The operation adjustment was also an effective method to increase the energy efficiency. For example, the operation adjustment of slurry circulation pumps could promote the energy-saving operation of WFGD system. Implication Statement The application of pollutant abatement technologies increases the internal energy consumption of the power plant, which will lead to an increase of power generation costs. The real-time energy consumption of the different pollutant abatement systems in a typical power unit is analyzed based on the dynamic operating data. Further, the influence of different operating parameters on the operating power of the system and the possible energy-saving potential are analyzed.

Regional differences in China's CO2 abatement cost

International Nuclear Information System (INIS)

He, Xiaoping

2015-01-01

Under a framework of output distance function with multiple outputs, the study discusses the carbon abatement cost at provincial and regional levels in China, using the shadow price analysis. The findings show that the abatement cost, reflecting the marginal opportunity cost of carbon reduction, varies greatly among the provinces. On average, the abatement cost of the eastern region was much higher than that of the mid-western region during the observed period. The findings provide evidence that the carbon prices in the current ETS pilots have been much lower than desired levels, implying inefficiency of the markets. The wide range of the abatement cost estimates supports that the equi-marginal principle does not hold for the regulations on carbon pollution at regional levels. The regional cost differences indicate the huge potential for China to minimize the total abatement cost with policy instruments that may motive the emissions moving from areas of low abatement cost to where the abatement cost is higher. For a few undeveloped provinces that are environmentally fragile and have high abatement cost, supplementary measures will be needed to reduce the negative impact of carbon cutbacks on the poor to the minimum. - Highlights: • The marginal abatement cost of CO 2 is defined by the shadow price measure. • A linear programming model based on distance function is established. • Marginal abatement costs at provincial level are empirical investigated. • The abatement cost varies across provinces and regions in China. • The findings provide evidence that the current ETS pilots are inefficient

Internationalization Process and Technological Capability Trajectory of Iguaçu

2012-07-01

Full Text Available This article focuses on the influence of the internationalization process in the evolution of technological capability. This implication was studied in Iguaçu between 1967 and 2009. To achieve the proposed goal it was used the Internationalization of Brazilian Export Producer Companies Model, built by Kraus (2006 and the Model of Technological Capabilities in Companies of Emerging Economies, built by Figueiredo (2004. The study found that different stages of internationalization require different functions and different levels of technology. The discussion proposed by this paper found a close association between the process of internationalization and the development of technological capability in the company studied. It can be concluded that for companies of Soluble Coffee to conquer, reach and remain competitive in international markets it should engage efforts to build diverse organizational skills, alliances and technological capabilities.

Marginal abatement cost curve for nitrogen oxides incorporating controls, renewable electricity, energy efficiency, and fuel switching.

Science.gov (United States)

Loughlin, Daniel H; Macpherson, Alexander J; Kaufman, Katherine R; Keaveny, Brian N

2017-10-01

A marginal abatement cost curve (MACC) traces out the relationship between the quantity of pollution abated and the marginal cost of abating each additional unit. In the context of air quality management, MACCs are typically developed by sorting control technologies by their relative cost-effectiveness. Other potentially important abatement measures such as renewable electricity, energy efficiency, and fuel switching (RE/EE/FS) are often not incorporated into MACCs, as it is difficult to quantify their costs and abatement potential. In this paper, a U.S. energy system model is used to develop a MACC for nitrogen oxides (NO x ) that incorporates both traditional controls and these additional measures. The MACC is decomposed by sector, and the relative cost-effectiveness of RE/EE/FS and traditional controls are compared. RE/EE/FS are shown to have the potential to increase emission reductions beyond what is possible when applying traditional controls alone. Furthermore, a portion of RE/EE/FS appear to be cost-competitive with traditional controls. Renewable electricity, energy efficiency, and fuel switching can be cost-competitive with traditional air pollutant controls for abating air pollutant emissions. The application of renewable electricity, energy efficiency, and fuel switching is also shown to have the potential to increase emission reductions beyond what is possible when applying traditional controls alone.

In this paper we investigate CO 2 emission scenarios for Colombia and the effects of implementing carbon taxes and abatement targets on the energy system. By comparing baseline and policy scenario results from two integrated assessment partial equilibrium models TIAM-ECN and GCAM and two general equilibrium models Phoenix and MEG4C, we provide an indication of future developments and dynamics in the Colombian energy system. Currently, the carbon intensity of the energy system in Colombia is low compared to other countries in Latin America. However, this trend may change given the projected rapid growth of the economy and the potential increase in the use of carbon-based technologies. Climate policy in Colombia is under development and has yet to consider economic instruments such as taxes and abatement targets. This paper shows how taxes or abatement targets can achieve significant CO 2 reductions in Colombia. Though abatement may be achieved through different pathways, taxes and targets promote the entry of cleaner energy sources into the market and reduce final energy demand through energy efficiency improvements and other demand-side responses. The electric power sector plays an important role in achieving CO 2 emission reductions in Colombia, through the increase of hydropower, the introduction of wind technologies, and the deployment of biomass, coal and natural gas with CO 2 capture and storage (CCS). Uncertainty over the prevailing mitigation pathway reinforces the importance of climate policy to guide sectors toward low-carbon technologies. This paper also assesses the economy-wide implications of mitigation policies such as potential losses in GDP and consumption. An assessment of the legal, institutional, social and environmental barriers to economy-wide mitigation policies is critical yet beyond the scope of this paper. - Highlights: • Four energy and economy-wide models under carbon mitigation scenarios are compared. • Baseline results show that CO

Full Text Available Dynamic capabilities are currently becoming an important extension of the theory of resources and capabilities that enables companies to adapt better in the current competitive environment. This paper examines how knowledge management, a dynamic function related to management or administration of a set of knowledge flows, develops thanks to the greater dynamism of social networks. It then shows how this relationship is especially strengthened by different technological capabilities. To achieve these goals, the paper examines the main tools that permit companies to develop an ability to achieve competitive advantage relative to the technological capabilities of managers and workers, social networks and knowledge management.

This study aims to identify the determinants of technological innovation capability of Malaysian-owned companies in the resources-based manufacturing, to identify the relationship between technological innovation capability (TIC) and technological innovation performance (TIP) for the resource-based manufacturing. Furthermore, this study also aims to identify innovation capability factors that need more emphasis and improvements from the respective authority. The scope of the study covers four industries which are petrochemical industries, pharmaceutical industries, palm oil-based industries and food processing industries which are located in the state of Selangor. Descriptive analysis, correlation analysis and performance capability analysis were used in this study. It was found that, technological innovation capabilities (TIC) for companies in the resource-based manufacturing are moderate. Factors such as policies capability, human resources capability and facilities capability have a positive relationship with the performance of technological innovation (TIP). These findings will help the government in making decisions and better implementation of policies to strengthen the competitiveness of the company, particularly in resource-based manufacturing.

Considerations upon the possibility of abating the pollution produced by thermal power plants

International Nuclear Information System (INIS)

Ataman, Eleonora

1992-01-01

Thermal power plants using fossil fuels in conventional boilers are among the most important man-made stationary sources of pollutant release. A review of the present possibilities to abate the pollution, mainly by abatement of releases at stack is presented. At present the unique viable solution applicable in Romania thermopower stations appears to be the use of catalytic technology based on NO x selective reduction with ammonia. Investments for pollution abatement installations for intra- or post-combustion burning gases in classic boilers appear to be 1/4 and 1/3 of the cost of a new thermal power plant and the maintenance costs of de-pollution installations even when the resulting products are rendered profitable, the cost of KWh will raise. Replacement of classical boilers by circulating fluidized bed boilers would solve entirely the SO 2 and NO x release issue. Investments for such boilers are lower than those implied by a new classical boiler equipped with supplementary installations for the removal of intra- and post-combustion gases. The only remaining drawback is waste resulting desulfurization which is disposed at the dump. (author)

Infectious disease risk in asbestos abatement workers.

Lange, John H; Mastrangelo, Giuseppe; Cegolon, Luca

2012-08-16

The current literature reports increased infectious disease occurrence in various construction occupations, as an important contributor to morbidity and mortality arising from employment.These observations should be expanded to asbestos abatement workers, as the abatement can create an environment favorable for bacterial, viral and fungal infections. Asbestos abatement work employs activities resulting in cuts, blisters and abrasions to the skin, work in a dirty environment and exposure to dust, mists and fumes.Furthermore, this population exhibits a high smoking rate which increases the risk of chronic obstructive pulmonary disease and respiratory infections.In addition, these workers also commonly employ respirators, which can accumulate dirt and debris magnifying exposure to microbes. Use of respirators and related types of personal protective equipment, especially if shared and in the close environment experienced by workers, may enhance communicability of these agents, including viruses. Abatement workers need to be provided with information on hazards and targeted by appropriate health education to reduce the infection risk. Epidemiological studies to investigate this risk in asbestos removers are recommended.

The evaluation performed in this study indicates that a new program is needed to efficiently provide a national actinide radioisotope enrichment capability to produce milligram-to-gram quantities of unique materials for user communities. This program should leverage past actinide enrichment, the recent advances in stable isotope enrichment, and assessments of the future requirements to cost effectively develop this capability while establishing an experience base for a new generation of researchers in this vital area. Preliminary evaluations indicate that an electromagnetic isotope separation (EMIS) device would have the capability to meet the future needs of the user community for enriched actinides. The EMIS technology could be potentially coupled with other enrichment technologies, such as irradiation, as pre-enrichment and/or post-enrichment systems to increase the throughput, reduce losses of material, and/or reduce operational costs of the base EMIS system. Past actinide enrichment experience and advances in the EMIS technology applied in stable isotope separations should be leveraged with this new evaluation information to assist in the establishment of a domestic actinide radioisotope enrichment capability.

Estrada, José M; Kraakman, N J R Bart; Lebrero, Raquel; Muñoz, Raúl

2012-01-01

The sensitivity of the economics of the five most commonly applied odour abatement technologies (biofiltration, biotrickling filtration, activated carbon adsorption, chemical scrubbing and a hybrid technology consisting of a biotrickling filter coupled with carbon adsorption) towards design parameters and commodity prices was evaluated. Besides, the influence of the geographical location on the Net Present Value calculated for a 20 years lifespan (NPV20) of each technology and its robustness towards typical process fluctuations and operational upsets were also assessed. This comparative analysis showed that biological techniques present lower operating costs (up to 6 times) and lower sensitivity than their physical/chemical counterparts, with the packing material being the key parameter affecting their operating costs (40-50% of the total operating costs). The use of recycled or partially treated water (e.g. secondary effluent in wastewater treatment plants) offers an opportunity to significantly reduce costs in biological techniques. Physical/chemical technologies present a high sensitivity towards H2S concentration, which is an important drawback due to the fluctuating nature of malodorous emissions. The geographical analysis evidenced high NPV20 variations around the world for all the technologies evaluated, but despite the differences in wage and price levels, biofiltration and biotrickling filtration are always the most cost-efficient alternatives (NPV20). When, in an economical evaluation, the robustness is as relevant as the overall costs (NPV20), the hybrid technology would move up next to BTF as the most preferred technologies.

Least cost, utility scale abatement from Australia's NEM (National Electricity Market). Part 2: Scenarios and policy implications

International Nuclear Information System (INIS)

Brear, M.J.; Jeppesen, M.; Chattopadhyay, D.; Manzie, C.; Alpcan, T.; Dargaville, R.

2016-01-01

This paper is the second of a two part study that considers least cost, greenhouse gas abatement pathways for an electricity system. Part 1 of this study formulated a model for determining these abatement pathways, and applied this model to Australia's NEM (National Electricity Market) for a single reference scenario. Part 2 of this study applies this model to different scenarios and considers the policy implications. These include cases where nuclear power generation and CCS (carbon capture and storage) are implemented in Australia, which is presently not the case, as well as a more detailed examination of how an extended, RPS (renewable portfolio standard) might perform. The effect of future fuel costs and different discount rates are also examined. Several results from this study are thought to be significant. Most importantly, this study suggests that Australia already has utility scale technologies, renewable and non-renewable resources, an electricity market design and an abatement policy that permit continued progress towards deep greenhouse gas abatement in its electricity sector. In particular, a RPS (renewable portfolio standard) appears to be close to optimal as a greenhouse gas abatement policy for Australia's electricity sector for at least the next 10–15 years. - Highlights: • Considers scenarios and policy implications for Australia's NEM (National Electricity Market). • An extended form of RPS (renewable portfolio standard) appears near optimal until roughly 2030. • For up to 80% abatement, the inclusion of nuclear achieves only marginal benefit by 2050. • CCS (Carbon capture and storage) does not appear competitive with current cost estimates.

The public health relevance of air pollution abatement.

Science.gov (United States)

Künzli, N

2002-07-01

Assuming a causal relationship between current levels of air pollution and morbidity/mortality, it is crucial to estimate the public health relevance of the problem. The derivation of air pollution attributable cases faces inherent uncertainties and requires influential assumptions. Based on the results of the trinational impact assessment study of Austria, France, and Switzerland, where prudent estimates of the air pollution attributable cases (mortality, chronic bronchitis incidence, hospital admissions, acute bronchitis among children, restricted activity days, asthma attacks) have been made, influential uncertainties are quantified in this review. The public health impact of smoking, environmental tobacco smoke, and air pollution on the prevalence of chronic cough/phlegm are outlined. Despite all methodological caveats, impact assessment studies clearly suggest that public health largely benefits from better air quality. The studies are selective underestimates as they are strongly driven by mortality, but do not include full quantification of the impact on morbidity and their consequences on quality of life among the diseased and the caregivers. Air pollution abatement strategies are usually political in nature, targeting at polities, regulation and technology in mobile or stationary sources rather than at individuals. It is of note that key clean air strategies converge into abatement of climate change. In general, energy consumption is very closely related to both air pollution and greenhouse gases. The dominant causes of both problems are the excessive and inefficient combustion of fossil fuel. Thus, for many policy options, the benefit of air pollution abatement will go far beyond what prudent health-impact assessments may derive. From a climate change and air pollution perspective, improved energy efficiency and a strong and decisive departure from the "fossil fuel" combustion society is a science-based must. Health professionals must raise their voices

A Methodology for Constructing Marginal Abatement Cost Curves for Climate Action in Cities

Directory of Open Access Journals (Sweden)

Nadine Ibrahim

2016-03-01

Full Text Available As drivers of climate action, cities are taking measures to reduce greenhouse gas (GHG emissions, which if left unabated pose a challenge to meeting long-term climate targets. The economics of climate action needs to be at the forefront of climate dialogue to prioritize investments among competing mitigation measures. A marginal abatement cost (MAC curve is an effective visualization of climate action that initiates a technical and economic discussion of the cost-effectiveness and abatement potential of such actions among local leaders, policy makers, and climate experts. More commonly demonstrated for countries, MAC curves need to be developed for cities because of their heterogeneity, which vary in their urban activities, energy supply, infrastructure stock, and commuting patterns. The methodology for constructing bottom-up MAC curves for cities is presented for technologies that offer fuel switching and/or energy efficiencies, while considering technology lifetimes, city-specific electricity and fuel prices, and emission intensities. Resulting MAC curves are unique to every city, and chart the pathway towards low-carbon growth by prioritizing measures based on cost-effectiveness. A case study of Toronto’s climate targets demonstrates the prioritization of select technologies. Leveraging MAC curves to support climate programs enables cities to strategically invest in financing climate action and designing incentives.

This study examines the renewable energy production of crops used for phytoremediation. Our analysis is based on a case study in the Campine region (Belgium and The Netherlands), where agricultural soils are diffusely contaminated with cadmium, lead, and zinc, with an enhanced risk for uptake of these metals in crops and leaching to the groundwater. However, the area has such a large extent (700 km 2 ) that conventional remediation is not applicable. Cultivation of crops for energy purposes on such land offers the opportunity to come up with an approach that efficiently uses contaminated agricultural land and that can be beneficial for both farmer and society. Performing a Life Cycle Analysis (LCA), we examined the energy and CO 2 abatement potential of willow (Salix spp.), silage maize (Zea mays L.), and rapeseed (Brassica napus L.) originating from contaminated land. Taking into account the marginal impact of the metals in the biomass on the energy conversion efficiency and on the potential use of the biomass and its rest products after conversion, digestion of silage maize with combustion of the contaminated digestate shows the best energetic and CO 2 abating perspectives. The replacement of cokes based electricity by willow is more efficient in CO 2 abatement than willow used in a Combined Heat and Power (CHP) unit, despite lower net energy production in the former option. Willow reaches the same energy production and same CO 2 abatement per hectare per year as silage maize when its biomass yield is respectively 13 and 8.7 Mg dm ha −1 y −1 . -- Highlights: ► We study the energy potential of Salix, Zea mays and Brassica after phytoremediation. ► The case study contains agricultural soils that are contaminated with cadmium. ► We include the impact of metals on energy conversion efficiency and rest product use. ► Higher biomass yields for Salix would make it energetically competitive with Z. mays.

System-wide and Superemitter Policy Options for the Abatement of Methane Emissions from the U.S. Natural Gas System

Science.gov (United States)

Mayfield, E. N.; Robinson, A. L.; Cohon, J. L.

2017-12-01

This work assesses trade-offs between system-wide and superemitter policy options for reducing methane emissions from compressor stations in the U.S. transmission and storage system. Leveraging recently collected national emissions and activity data sets, we developed a new process-based emissions model implemented in a Monte Carlo simulation framework to estimate emissions for each component and facility in the system. We find that approximately 83% of emissions, given the existing suite of technologies, have the potential to be abated, with only a few emission categories comprising a majority of emissions. We then formulate optimization models to determine optimal abatement strategies. Most emissions across the system (approximately 80%) are efficient to abate, resulting in net benefits ranging from 160M to 1.2B annually across the system. The private cost burden is minimal under standard and tax instruments, and if firms market the abated natural gas, private net benefits may be generated. Superemitter policies, namely, those that target the highest emitting facilities, may reduce the private cost burden and achieve high emission reductions, especially if emissions across facilities are highly skewed. However, detection across all facilities is necessary regardless of the policy option and there are nontrivial net benefits resulting from abatement of relatively low-emitting sources.

Optimal Coordination Strategy of Regional Vertical Emission Abatement Collaboration in a Low-Carbon Environment

Directory of Open Access Journals (Sweden)

Daming You

2018-02-01

Full Text Available This study introduces a time factor into a low-carbon context, and supposes the contamination control state of local government and the ability of polluting enterprise to abate emissions as linear increasing functions in a regional low-carbon emission abatement cooperation chain. The local government effectuates and upholds the low-carbon development within the jurisdiction that is primarily seeking to transform regional economic development modes, while the polluting enterprise abates the amounts of emitted carbon in the entire period of product through simplifying production, facilitating decontamination, and adopting production technology, thus leading to less contamination. On that basis, we infer that the coordinated joint carbon reduction model and two decentralization contracts expound the dynamic coordination strategy for a regional cooperation chain in terms of vertical carbon abatement. Furthermore, feedback equilibrium strategies that are concerned with several diverse conditions are compared and analyzed. The main results show that a collaborative centralized contract is able to promote the regional low-carbon cooperation chain in order to achieve a win–win situation in both economic and environmental performance. Additionally, the optimal profits of the entire regional low-carbon cooperation channel under an integration scenario evidently outstrip that of two non-collaborative decentralization schemes. Eventually, the validity of the conclusions is verified with a case description and numerical simulation, and the sensitivity of the relevant parameters is analyzed in order to lay a theoretical foundation and thus facilitate the sustainable development of a regional low-carbon environment.

A number of questions having to do with the themes of abatement and adaptation are discussed. Under the first rubric are questions of future concentrations of radiatively active trace gases, the linkage of these gases with greenhouse warming, and other environmental problems. Also examined in the abatement context are opportunities to reduce fossil fuel use and therefore the emission of greenhouse gases, and the likelihood that natural forest expansion may provide an opportunity to control the rate of carbon dioxide (CO2) accumulation in the atmosphere. Also discussed are the possible effects of greenhouse warming on agriculture in the United States and in the developing world. Finally, some suggestions are given on capturing and retaining interest in greenhouse warming on the part of the decision making public

To examine recent developments in health-related scientific capabilities, the impact of lines of incentives on reducing regional scientific imbalances, and university-industry research collaboration in Brazil. Data were obtained from the Conselho Nacional de Desenvolvimento Científico e Tecnológico (Brazilian National Council for Scientific and Technological Development) databases for the years 2000 to 2010. There were assessed indicators of resource mobilization, research network structuring, and knowledge transfer between science and industry initiatives. Based on the regional distribution map of health-related scientific and technological capabilities there were identified patterns of scientific capabilities and science-industry collaboration. There was relative spatial deconcentration of health research groups and more than 6% of them worked in six areas of knowledge areas: medicine, collective health, dentistry, veterinary medicine, ecology and physical education. Lines of incentives that were adopted from 2000 to 2009 contributed to reducing regional scientific imbalances and improving preexisting capabilities or, alternatively, encouraging spatial decentralization of these capabilities. Health-related scientific and technological capabilities remain highly spatially concentrated in Brazil and incentive policies have contributed to reduce to some extent these imbalances.

Hossein Moradi

2010-10-01

Full Text Available Enterprise Application Integration (EAI technologies facilitate the sharing of information and business processes of interrelated information systems in order to achieve the target integrated systems. Different EAI solutions and technologies provide various capabilities which lead to the complexity of their evaluation process. To reduce this complexity, appropriate tools for evaluating the functional capabilities of EAI technologies are required. This paper proposes a new framework for evaluating the functional capabilities of EAI technologies, which simplify the process of evaluating the functional capabilities of intra-enterprise integration technologies and solutions.The proposed framework for evaluating the EAI technologies was enhanced using the structural and conceptual aspects of previous frameworks. It offers a new schema for which various EAI technologies are categorized in different classes and are evaluated based on their supporting level for functional integration capabilities’ criteria.The new framework offers two lists containing integration technologies and their associated classifications, and functional capabilities of integration technologies. The proposed framework is a novel one which can be used by information system experts for evaluation and comparison purposes of various integration technologies.

Building technological capability within satellite programs in developing countries

Science.gov (United States)

Wood, Danielle; Weigel, Annalisa

2011-12-01

This paper explores the process of building technological capability in government-led satellite programs within developing countries. The key message is that these satellite programs can learn useful lessons from literature in the international development community. These lessons are relevant to emerging satellite programs that leverage international partnerships in order to establish local capability to design, build and operate satellites. Countries with such programs include Algeria, Nigeria, Turkey, Malaysia and the United Arab Emirates. The paper first provides background knowledge about space activity in developing countries, and then explores the nuances of the lessons coming from the international development literature. Developing countries are concerned with satellite technology because satellites provide useful services in the areas of earth observation, communication, navigation and science. Most developing countries access satellite services through indirect means such as sharing data with foreign organizations. More countries, however, are seeking opportunities to develop satellite technology locally. There are objective, technically driven motivations for developing countries to invest in satellite technology, despite rich debate on this topic. The paper provides a framework to understand technical motivations for investment in satellite services, hardware, expertise and infrastructure in both short and long term. If a country decides to pursue such investments they face a common set of strategic decisions at the levels of their satellite program, their national context and their international relationships. Analysis of past projects shows that countries have chosen diverse strategies to address these strategic decisions and grow in technological capability. What is similar about the historical examples is that many countries choose to leverage international partnerships as part of their growth process. There are also historical examples from

Final Report on Testing of Off-Gas Treatment Technologies for Abatement of Atmospheric Emissions of Chlorinated Volatile Organic Compounds

Jarosch, T.R.; Haselow, J.S.; Rossabi, J.; Burdick, S.A.; Raymond, R.; Young, J.E.; Lombard, K.H.

1995-01-01

The purpose of this report is to summarize the results of the program for off-gas treatment of atmospheric emissions of chlorinated volatile organic compounds (CVOCs), in particular trichloroethylene (TCE) and perchloroethylene (PCE). This program was funded through the Department of Energy Office of Technology Development's VOC's in Non-Arid Soils Integrated Demonstration (VNID). The off-gas treatment program was initiated after testing of in-situ air stripping with horizontal wells was completed (Looney et al., 1991). That successful test expectedly produced atmospheric emissions of CVOCs that were unabated. It was decided after that test that an off-gas treatment is an integral portion of remediation of CVOC contamination in groundwater and soil but also because several technologies were being developed across the United States to mitigate CVOC emissions. A single platform for testing off-gas treatment technologies would facilitate cost effective evaluation of the emerging technologies. Another motivation for the program is that many CVOCs will be regulated under the Clean Air Act Amendments of 1990 and are already regulated by many state regulatory programs. Additionally, compounds such as TCE and PCE are pervasive subsurface environmental contaminants, and, as a result, a small improvement in terms of abatement efficiency or cost will significantly reduce CVOC discharges to the environment as well as costs to United States government and industry

Life cycle assessment (LCA) of slow pyrolysis biochar systems (PBS) in the UK for small, medium and large scale process chains and ten feedstocks was performed, assessing carbon abatement and electricity production. Pyrolysis biochar systems appear to offer greater carbon abatement than other bioenergy systems. Carbon abatement of 0.7-1.3 t CO 2 equivalent per oven dry tonne of feedstock processed was found. In terms of delivered energy, medium to large scale PBS abates 1.4-1.9 t CO 2 e/MWh, which compares to average carbon emissions of 0.05-0.30 t CO 2 e/MWh for other bioenergy systems. The largest contribution to PBS carbon abatement is from the feedstock carbon stabilised in biochar (40-50%), followed by the less certain indirect effects of biochar in the soil (25-40%)-mainly due to increase in soil organic carbon levels. Change in soil organic carbon levels was found to be a key sensitivity. Electricity production off-setting emissions from fossil fuels accounted for 10-25% of carbon abatement. The LCA suggests that provided 43% of the carbon in the biochar remains stable, PBS will out-perform direct combustion of biomass at 33% efficiency in terms of carbon abatement, even if there is no beneficial effect upon soil organic carbon levels from biochar application. - Research highlights: → Biochar systems offer greater carbon abatement than combustion or gasification. → Carbon abatement of 0.7-1.4t CO 2 e/dry tonne of feedstock processed was found. → Change in soil organic carbon stocks induced by biochar is the key sensitivity. → Biochar systems produce less electricity then combustion or gasification.

The energy sector was responsible for approximately 84% of carbon dioxide equivalent (CO₂e) greenhouse gas (GHG) emissions in the U.S. in 2012 (EPA 2014a). Methane is the second most important GHG, contributing 9% of total U.S. CO₂e emissions. A large portion of those methane emissions result from energy production and use; the natural gas, coal, and oil industries produce approximately 39% of anthropogenic methane emissions in the U.S. As a result, fossil-fuel systems have been consistently identified as high priority sectors to contribute to U.S. GHG reduction goals (White House 2015). Only two studies have recently attempted to quantify the abatement potential and cost associated with the breadth of opportunities to reduce GHG emissions within natural gas, oil, and coal supply chains in the United States, namely the U.S. Environmental Protection Agency (EPA) (2013a) and ICF (2014). EPA, in its 2013 analysis, estimated the marginal cost of abatement for non-CO₂ GHG emissions from the natural gas, oil, and coal supply chains for multiple regions globally, including the United States. Building on this work, ICF International (ICF) (2014) provided an update and re-analysis of the potential opportunities in U.S. natural gas and oil systems. In this report we synthesize these previously published estimates as well as incorporate additional data provided by ICF to provide a comprehensive national analysis of methane abatement opportunities and their associated costs across the natural gas, oil, and coal supply chains. Results are presented as a suite of marginal abatement cost curves (MACCs), which depict the total potential and cost of reducing emissions through different abatement measures. We report results by sector (natural gas, oil, and coal) and by supply chain segment - production, gathering and boosting, processing, transmission and storage, or distribution - to facilitate identification of which sectors and supply chain

FUEL/CARBON PRICE VS. ABATEMENT TECHNOLOGY IN FREIGHT TRANSPORT

Directory of Open Access Journals (Sweden)

Eugen Ferdinand Spangenberg

Full Text Available The current situation is the exponential increase in greenhouse gases (GHG, which is mainly caused by industrial and transport activities. The recent Paris agreement in 2015 (Framework Convention on Climate Change COP21, UNFCCC made it clear to everyone that CO2 emissions are to be limited in all areas of life. Alternative fuels with a lower environmental impact than carbon (CO2 emissions are hard to find if the overall footprint is to be taken into account. Nevertheless, there are some fuels that have less impact on climate change. One the other hand, the production of biofuels is a controversial matter, although it is a viable alternative to emissions reduction. CNG or LNG-powered vehicles are also better in terms of environmental pollution, but are hardly better with regard to CO2 impact when a Life Cycle Assessment (LCA is carried out. LNG (liquid natural gas, for example, is the future fuel in the maritime sector because of the stricter environmental regulations (SOx,NOx in the shipping industry. The battery-powered vehicle is another example of an environmentally friendly solution. The afore-mentioned measures can be considered as “abatement“ necessary in order to limit CO2 impact. The study shows that there are significant differences in the environmental impact between transport systems and the corresponding drive-system or associated energy base. The polluter should pay, which is a common basic principle in economic research. The Emission Trading Scheme (ETS has been introduced in order to ensure a reduction in CO2 output – emissions come with a price tag. An overall view is necessary, both en-vironmental and economic impact must be reconciled (cf. Spangenberg - TQI. The future viability of the transport system as we know it may change significantly over time if new environmental requirements or e.g. CO2 taxes or ETS are introduced in the freight sector. The abatement of CO2 should be effected primarily through technological

Yijun, Liu; Yu, Fang; Xiaoman, He; Yongyou, Wang

The general mathematic mode of computing noise abatement is commonly used for most project planning and appraisal of environmental noise abatement projects. However, the inconvenient and impracticable mode and algorithm usually cannot meet the real world computation and testing. Therefore, a more practicable abatement mode and algorithm (multiple noise sources with multiband under sound barriers) which had been applied to VR based simulation system. That implemented the function of real-time demonstrating noise scattering condition within 3D virtual space, furthermore, with sound barriers added in 3D scene, the effectiveness of denoise by sound barriers also can be demonstrated within this system. That provides a significant solution for environmental noise abatement projects as a whole.

Full Text Available Abstract. The relationship between strategic technology planning and the overall business strategy has been one of the growing fields that attract much interest both from academics and industrials point of view. The increasingly important role that technology plays in today’s business success is well established.Strategic technology planning activities--within a corporate level--are often implemented by applying integrated planning instrument, which allow firms to consider both technology-oriented and product-oriented aspects. This paper is an attempt to explore the role of strategic planning in the high tech industry using a specific case of aerospace industry in Indonesia.  In order to compete effectively inthe open global marketplace, the company must learn to integrate technology managementwith strategic planning. In other words, all top managers have to linktheir technology capabilities to marketing requirements.Keywords:  technology planning; business strategy; technology capability; marketing requirement; strategic mix

Marginal abatement cost curves and the optimal timing of mitigation measures

International Nuclear Information System (INIS)

Vogt-Schilb, Adrien; Hallegatte, Stéphane

2014-01-01

Decision makers facing abatement targets need to decide which abatement measures to implement, and in which order. Measure-explicit marginal abatement cost curves depict the cost and abating potential of available mitigation options. Using a simple intertemporal optimization model, we demonstrate why this information is not sufficient to design emission reduction strategies. Because the measures required to achieve ambitious emission reductions cannot be implemented overnight, the optimal strategy to reach a short-term target depends on longer-term targets. For instance, the best strategy to achieve European's −20% by 2020 target may be to implement some expensive, high-potential, and long-to-implement options required to meet the −75% by 2050 target. Using just the cheapest abatement options to reach the 2020 target can create a carbon-intensive lock-in and make the 2050 target too expensive to reach. Designing mitigation policies requires information on the speed at which various measures to curb greenhouse gas emissions can be implemented, in addition to the information on the costs and potential of such measures provided by marginal abatement cost curves. - Highlights: • Classification of existing Marginal Abatement Cost Curves (MACC). • MACCs do not provide separated data on the speed at which measures can be implemented. • Optimal measures to reach a short-term target depend on longer-term targets. • Unique carbon price or aggregated emission-reduction target may be insufficient. • Room for short-term sectoral policies if agents are myopic or governments cannot commit

Dynamics of carbon abatement in the Second Generation Model

International Nuclear Information System (INIS)

Sands, Ronald D.

2004-01-01

The Second Generation Model (SGM) is a collection of computable-general-equilibrium models developed for analysis of policies to reduce greenhouse gas emissions. Behavior of the Second Generation Model, with respect to changes in carbon prices, can be summarized using marginal abatement cost curves. Marginal abatement costs vary over time, as capital stocks adjust to a new set of prices, and across countries, depending in part on the mix of fuels in the existing energy system. This paper documents the production structure in SGM, marginal abatement cost curves derived from SGM with constant-carbon-price experiments, an application to several Energy Modeling Forum scenarios, and a methodology for including carbon capture and disposal in SGM

Greenhouse gas abatement cost curves of the residential heating market. A microeconomic approach

International Nuclear Information System (INIS)

Dieckhoener, Caroline; Hecking, Harald

2012-01-01

In this paper, we develop a microeconomic approach to deduce greenhouse gas abatement cost curves of the residential heating sector. By accounting for household behavior, we find that welfare-based abatement costs are generally higher than pure technical equipment costs. Our results are based on a microsimulation of private households' investment decision for heating systems until 2030. The households' investment behavior in the simulation is derived from a discrete choice estimation which allows investigating the welfare costs of different abatement policies in terms of the compensating variation and the excess burden. We simulate greenhouse gas abatements and welfare costs of carbon taxes and subsidies on heating system investments until 2030 to deduce abatement curves. Given utility maximizing households, our results suggest a carbon tax to be the welfare efficient policy. Assuming behavioral misperceptions instead, a subsidy on investments might have lower marginal greenhouse gas abatement costs than a carbon tax.

On the cost-effective abatement of CO2-options taking consumer behaviour into account

International Nuclear Information System (INIS)

Wietschel, M.; Rentz, O.

1995-01-01

The current ecopolitical discussion focusses on the greenhouse effect and the consequent political aim to abate anthropogenic CO 2 emissions. Studies on individual measures for CO 2 abatement and on the development of efficient abatement strategies are already at hand. There is one aspect, however, that has hardly been dealt with as yet: If CO 2 abatement suceeds as it is planned by the Federal Government, then energy and prices will rise considerably, and this will curb the demand for energy. Any efficient abatement strategy must take this into account. The article presents a new concept for energy-emission models that takes consumer behaviour into account and discusses efficient CO 2 abatement strategies following from the application of such models.

Measurements of environmental policy for air pollution abatement

Friedrich, R.

1993-01-01

The first part of the study goes into the determination of efficient strategies for the reduction of air pollutants. The developed method is not only derived theoretically but is tested with the concrete example of emissions sources of a German state. The second part goes into the question what the government can do in order to attain that air pollution abatement measures recognized as being efficient will be put into practice. As market economy mechanisms have advantages over central state planning in the allocation of economic resources the question arises if not also for environmental protection market economy tools may contribute to an improvement of the efficiency of air pollution abatement. Therefore the suitability of different tools of environmental policy for the realization of efficient air pollution abatement is investigated and evaluated. This is again not done abstractly but with existing emission sources. (orig./HSCH). 32 figs., 12 tabs [de

GAC as a method for radon abatement

Martin, R.D.; Smith, K.A.

1990-01-01

Perhaps one of the most mysterious abatement procedures is that of the remediation of waterborne radon contamination in residential structures. Many mitigators have been led to believe that the use of GAC as an abatement technique is in appropriate due to the potential creation of a hazardous waste disposal problem. This paper sheds light on the use of GAC as a true alternative to costly aeration mitigation techniques, and can be used as a resource tool for mitigators who need to understand the limits of activity surrounding GAC, and what, if any, shielding may be needed for the protection of residential occupants

Efficient air pollution abatement for regions in China

Energy Technology Data Exchange (ETDEWEB)

Hu, J.L. [National Chiao Tung University, Taipei (Taiwan). Inst. for Business & Management

2006-08-15

This paper computes the efficient air pollution abatement ratios of 30 regions in China during the period 1996-2002. Three air emissions (SO{sub 2}, soot and dust) are considered. Data envelopment analysis (DEA) with a single output (real GDP) and five inputs (labour, real capital stock, SO{sub 2}, dust and soot emissions) is used to compute the target emissions of each region for each year. The efficient abatement ratios of each region in each year are then obtained by dividing the target emission by the actual emission of an air pollutant. Our major findings are: 1. The eastern area is the most efficient region with respect to SO{sub 2}, soot and dust emissions in every year during the research period. 2. The eastern, central and western areas have the lowest, medium and highest 1996-2002 average target abatement ratios of SO, (22.09%, 42.23% and 57.58%), soot (26.19%, 56.34% and 66.37%) and dust (15.20%, 29.09% and 40.59%), respectively. 3. These results are consistent with the Environmental Kuznets Curve (EKC) theory, whereby a more developed area will use environmental goods more efficiently than a less developed area. 4. Compared to dust emission, the average target abatement ratios for SO{sub 2} and soot emissions (as direct outcomes of burning coal) are relatively much higher for all three areas.

In addition to causing domestic and regional environmental effects, many air pollutants contribute to radiative forcing (RF) of the climate system. However, climate effects are not considered when cost-effective abatement targets for these pollutants are established, nor are they included in current international climate agreements. We construct air pollution abatement scenarios in 2030 which target cost-effective reductions in RF in the EU, USA, and China and compare these to abatement scenarios which instead target regional ozone effects and particulate matter concentrations. Our analysis covers emissions of PM (fine, black carbon and organic carbon), SO 2 , NO x , CH 4 , VOCs, and CO. We find that the effect synergies are strong for PM/BC, VOC, CO and CH 4 . While an air quality strategy targeted at reducing ozone will also reduce RF, this will not be the case for a strategy targeting particulate matter. Abatement in China dominates RF reduction, but there are cheap abatement options also available in the EU and USA. The justification for international cooperation on air quality issues is underlined when the co-benefits of reduced RF are considered. Some species, most importantly SO 2 , contribute a negative forcing on climate. We suggest that given current knowledge, NO x and SO 2 should be ignored in RF-targeted abatement policies.

Manufacturing capability as a technological development indicator in the pharmaceutical industry

Directory of Open Access Journals (Sweden)

John Jairo Gallo Castro

2010-01-01

Full Text Available The pharmaceutical industrial has five subsectors: medicines, cosmetics, phytotherapeutics, cleaning products and medical devices. The medicine subsector consists of organisations producing, importing and selling these products. Most studies about this industry have been guided by economic interests without assessing technological aspects of production. This article was aimed at proposing a methodology for assessing and describing the medicine sector according to its technological development by using the manufacturing capability concept. The main information was taken from the Colombian Medicaments and Food Surveillance Institute’s (Instituto Nacional de Vigilancia de Medicamentos y Alimentos - INVIMA databases related to pharmaceutical plant production in Bogotá, including material transformation facilities. This study led to three characteristics being identified for defining the pharmaceutical industry’s manufacturing capability: that related to the pharmacological group to which active pharmaceutical ingredients belong, that linked to specifications regarding medicines’ sterility and that related to the technology required for manufacturing each pharmaceutical product. An analysis of these features has thus been presented and some technologies have been identified which have not been transferred or assimilated by the organisations being studied. It was found that manufacturing capability should be considered as being an indicator of the degree of technological development in these subsectors in Colombia.

Power and cogeneration technology environomic performance typification in the context of CO2 abatement part II: Combined heat and power cogeneration

2010-01-01

This is the second of a series of two articles, dealing with a new approach of environomic (thermodynamic, economic and environmental) performance 'Typification' and optimization of power generation technologies. This part treats specifically of combined heat and power (CHP) cogeneration technologies in the context of CO 2 abatement and provides a methodology for a flexible and fast project based CHP system design evaluation. One of the aspect of the approach is the post-optimization integration of the operating and capital costs, in order to effectively deal with the uncertainty of the project specific design and operation conditions (fuel, electricity and heat selling prices, project financial conditions such as investment amortization periods, annual operating hours, etc). In addition the approach also allows to efficiently evaluate the influence of the external cost such as the CO 2 tax level under a tax scheme or the CO 2 permit price in the emission trading market. Application examples, including gas turbine and combined cycles are treated with the proposed methodology, by using superstructure based generic environomic models and a multi-objective optimizer.

Abatement vs. treatment for efficient diffuse source water pollution management in terrestrial-marine systems.

Roebeling, P C; Cunha, M C; Arroja, L; van Grieken, M E

2015-01-01

Marine ecosystems are affected by water pollution originating from coastal catchments. The delivery of water pollutants can be reduced through water pollution abatement as well as water pollution treatment. Hence, sustainable economic development of coastal regions requires balancing of the marginal costs from water pollution abatement and/or treatment and the associated marginal benefits from marine resource appreciation. Water pollution delivery reduction costs are, however, not equal across abatement and treatment options. In this paper, an optimal control approach is developed and applied to explore welfare maximizing rates of water pollution abatement and/or treatment for efficient diffuse source water pollution management in terrestrial-marine systems. For the case of diffuse source dissolved inorganic nitrogen water pollution in the Tully-Murray region, Queensland, Australia, (agricultural) water pollution abatement cost, (wetland) water pollution treatment cost and marine benefit functions are determined to explore welfare maximizing rates of water pollution abatement and/or treatment. Considering partial (wetland) treatment costs and positive water quality improvement benefits, results show that welfare gains can be obtained, primarily, through diffuse source water pollution abatement (improved agricultural management practices) and, to a minor extent, through diffuse source water pollution treatment (wetland restoration).

2008-01-01

Road noise nuisance is a huge problem in the Nordic countries, and it seems diffi cult for Nordic countries to meet national targets for its reduction. One reason for this is the lack of municipal activities in the fi eld.

A bottom-up method to develop pollution abatement cost curves for coal-fired utility boilers

International Nuclear Information System (INIS)

Vijay, Samudra; DeCarolis, Joseph F.; Srivastava, Ravi K.

2010-01-01

This paper illustrates a new method to create supply curves for pollution abatement using boiler-level data that explicitly accounts for technology cost and performance. The Coal Utility Environmental Cost (CUECost) model is used to estimate retrofit costs for five different NO x control configurations on a large subset of the existing coal-fired, utility-owned boilers in the US. The resultant data are used to create technology-specific marginal abatement cost curves (MACCs) and also serve as input to an integer linear program, which minimizes system-wide control costs by finding the optimal distribution of NO x controls across the modeled boilers under an emission constraint. The result is a single optimized MACC that accounts for detailed, boiler-specific information related to NO x retrofits. Because the resultant MACCs do not take into account regional differences in air-quality standards or pre-existing NO x controls, the results should not be interpreted as a policy prescription. The general method as well as NO x -specific results presented here should be of significant value to modelers and policy analysts who must estimate the costs of pollution reduction.

Broadening the Appeal of Marginal Abatement Cost Curves: Capturing Both Carbon Mitigation and Development Benefits of Clean Energy Technologies; Preprint

Low emission development strategies (LEDS) articulate policies and implementation plans that enable countries to advance sustainable, climate-resilient development and private sector growth while significantly reducing the greenhouse gas (GHG) emissions traditionally associated with economic growth. In creating a LEDS, policy makers often have access to information on abatement potential and costs for clean energy technologies, but there is a scarcity of economy-wide approaches for evaluating and presenting information on other dimensions of importance to development, such as human welfare, poverty alleviation, and energy security. To address this shortcoming, this paper proposes a new tool for communicating development benefits to policy makers as part of a LEDS process. The purpose of this tool is two-fold: 1. Communicate development benefits associated with each clean energy-related intervention; 2. Facilitate decision-making on which combination of interventions best contributes to development goals. To pilot this tool, the authors created a visual using data on developmental impacts identified through the Technology Needs Assessment (TNA) project in Montenegro. The visual will then be revised to reflect new data established through the TNA that provides information on cost, GHG mitigation, as well as the range and magnitude of developmental impacts.

Marginal Abatement Cost of CO2 in China Based on Directional Distance Function: An Industry Perspective

Directory of Open Access Journals (Sweden)

Bowen Xiao

2017-01-01

Full Text Available Industrial sectors account for around 70% of the total energy-related CO2 emissions in China. It is of great importance to measure the potential for CO2 emissions reduction and calculate the carbon price in industrial sectors covered in the Emissions Trading Scheme and carbon tax. This paper employs the directional distance function to calculate the marginal abatement costs of CO2 emissions during 2005–2011 and makes a comparative analysis between our study and the relevant literature. Our empirical results show that the marginal abatement costs vary greatly from industry to industry: high marginal abatement costs occur in industries with low carbon intensity, and vice versa. In the application of the marginal abatement cost, the abatement distribution scheme with minimum cost is established under different abatement targets. The conclusions of abatement distribution scheme indicate that those heavy industries with low MACs and high carbon intensity should take more responsibility for emissions reduction and vice versa. Finally, the policy implications for marginal abatement cost are provided.

Human health risks associated with asbestos abatement.

Science.gov (United States)

Chrostowski, P C; Foster, S A; Anderson, E L

1991-09-01

Upperbound lifetime excess cancer risks were calculated for activities associated with asbestos abatement using a risk assessment framework developed for EPA's Superfund program. It was found that removals were associated with cancer risks to workers which were often greater than the commonly accepted cancer risk of 1 x 10(-6), although lower than occupational exposure limits associated with risks of 1 x 10(-3). Removals had little effect in reducing risk to school populations. Risks to teachers and students in school buildings containing asbestos were approximately the same as risks associated with exposure to ambient asbestos by the general public and were below the levels typically of concern to regulatory agencies. During abatement, however, there were increased risks to both workers and nearby individuals. Careless, everyday building maintenance generated the greatest risk to workers followed by removals and encapsulation. If asbestos abatement was judged by the risk criteria applied to EPA's Superfund program, the no-action alternative would likely be selected in preference to removal in a majority of cases. These conclusions should only be interpreted within the context of an overall asbestos risk management program, which includes consideration of specific fiber types and sizes, sampling and analytical limitations, physical condition of asbestos-containing material, episodic peak exposures, and the number of people potentially exposed.

Technological capability accumulation in the 'maquila industry' in Mexico

Directory of Open Access Journals (Sweden)

Gabriela Dutrénit

Full Text Available From the mid-1960s, 'maquila' plants were established in the Mexican Northern border. The Mexican model was based on foreign firms establishing their own assembly plants. Even though this model was less successful than that of East and South East Asian in terms of several techno-economic indicators, it has largely contributed to employment generation. However, as a result of internal learning process and changes in the global firms strategies, several 'maquilas' operating in Mexico have undergone important qualitative changes. During the 1990s there was a change in the nature of their productive and technological activities towards more complex products and more innovative technological activities. In contrast, other dimensions have evolved slowly, such as the engagement of Mexican suppliers in global supply chains. The aim of this paper is to discuss an analytical framework to help study the technological capability accumulation in the 'maquila' industry in Mexico. Based on that the paper seeks to examine levels of technological capability accumulation of three maquilas, and to bring to light some stylized facts of the accumulation process in this industry. The analytical framework proposed draws on the taxonomy of technological capabilities proposed by Bell & Pavitt (1995 for the manufacturing industry in developing countries and its further adaptations and applications carried in Figueiredo (2001 and Ariffin & Figueiredo (2003, 2004. This paper adapts it to the particularities of the 'maquila' industry in Mexico. The new taxonomy includes technical functions that are relevant to this industry and redefines activities that correspond to various levels of accumulation. This paper is based on a case study methodology. The cases are the business lines of three maquilas in Ciudad Juarez: Thomson Multimedia, Philips Corp. and Delphi Corp. Two business lines correspond to the consumer electronics industry and the third is specialized on electronic

This paper looks at the impact of ETC on the costs and benefits of different abatement strategies using a modified version of the PAGE2002 model. It was found that for most standard abatement paths there would be an initial 'learning investment' required that would substantially reduce the unit costs of CO 2 abatement as compared to a business as usual scenario. Furthermore, optimising an abatement program where ETC has been included leads to an increase in cost uncertainty during the period of widespread CO 2 abatements due to our lack of knowledge of the learning investments involved. Finally, the inclusion of ETC leads to a slightly deferred optimised abatement path followed by a rapid abatement program. Together, the results draw attention to the possibilities of 'uncovering uncertainty' through proactive abatements. 'Learning about learning' could become an important consideration for any plan to optimise future abatements

Marginal abatement cost curves for NOx that account for ...

Science.gov (United States)

A marginal abatement cost curve (MACC) traces out the relationship between the quantity of pollution abated and the marginal cost of abating each additional unit. In the context of air quality management, MACCs typically are developed by sorting end-of-pipe controls by their respective cost effectiveness. Alternative measures, such as renewable electricity, energy efficiency, and fuel switching (RE/EE/FS), are not considered as it is difficult to quantify their abatement potential. In this paper, we demonstrate the use of an energy system model to develop a MACC for nitrogen oxides (NOx) that incorporates both end-of-pipe controls and these alternative measures. We decompose the MACC by sector, and evaluate the cost-effectiveness of RE/EE/FS relative to end-of-pipe controls. RE/EE/FS are shown to produce considerable emission reductions after end-of-pipe controls have been exhausted. Furthermore, some RE/EE/FS are shown to be cost-competitive with end-of-pipe controls. Demonstrate how the MARKAL energy system model can be used to evaluate the potential role of renewable electricity, energy efficiency and fuel switching (RE/EE/FS) in achieving NOx reductions. For this particular analysis, we show that RE/EE/FSs are able to increase the quantity of NOx reductions available for a particular marginal cost (ranging from $5k per ton to $40k per ton) by approximately 50%.

The purpose of this article is to examine the methods and equipment for abating waste gases and water produced during the manufacture of semiconductor materials and devices. Three separating methods and equipment are used to control three different groups of electronic wastes. The first group includes arsine and phosphine emitted during the processes of semiconductor materials manufacture. The abatement procedure for this group of pollutants consists of adding iodates, cupric and manganese salts to a multiple shower tower (MST) structure. The second group includes pollutants containing arsenic, phosphorus, HF, HCl, NO2, and SO3 emitted during the manufacture of semiconductor materials and devices. The abatement procedure involves mixing oxidants and bases in an oval column with a separator in the middle. The third group consists of the ions of As, P and heavy metals contained in the waste water. The abatement procedure includes adding CaCO3 and ferric salts in a flocculation-sedimentation compact device equipment. Test results showed that all waste gases and water after the abatement procedures presented in this article passed the discharge standards set by the State Environmental Protection Administration of China.

Abate distribution and dengue control in rural Cambodia.

Science.gov (United States)

Khun, Sokrin; Manderson, Lenore H

2007-02-01

Sustainable public health and community collaboration and partnerships are essential for the effective elimination of vector breeding sites to prevent dengue fever. A prerequisite is that community members appreciate the importance of the infection, understand its transmission and preventive activities, and are able to translate such knowledge to action. In this paper, we draw on an ethnographic study of two villages in the eastern province of Kampong Cham, using data collected from qualitative research methods and entomological surveys to describe community knowledge of the vector, practices related to the reduction of breeding sources, and the effectiveness of temephos to control larvae. During the study period, temephos (distributed as Abate) was applied in water containers only in the rainy season, although these containers were also positive with larvae in the dry season. Discarded containers, ignored in terms of control activities, had twice the number of larvae as water storage containers. The continued reliance on Abate creates financial and technical problems, while its inappropriate distribution raises the possibility of larvicide resistance. Based on research findings, we argue that control strategies emphasizing the use of Abate should be reconsidered.

Economic incentives for optimal sulfur abatement in Europe

International Nuclear Information System (INIS)

Halkos, G.E.

1995-01-01

This article reviews and develops theoretical and empirical representations of economic incentives for implementing pollution control strategies. A number of alternative economic instruments exist, which, if applied internationally, could encourage implementation of abatement strategies by counties. The article considers means of persuading countries to minimize abatement costs. A comparison between the pollution targets achieved by the imposition of a uniform charge rate and by differentiated charge rates is discussed, and empirical results are provided with associated conclusions. These results are compared with a simple standards setting in the form of critical loads, in order to assess empirically if economic instruments work better than regulations

Health costs caused by oil extraction air emissions and the benefits from abatement: the case of Kazakhstan

International Nuclear Information System (INIS)

Netalieva, Indira; Wesseler, Justus; Heijman, Wim

2005-01-01

The methodology and results of a cost-benefit analysis of air quality control during oil production in the Caspian Region in Kazakhstan are presented. The benefits are defined as the decrease in health costs from reduced air pollution. The health costs are the income losses which depend on the attributes of illness (duration and number of symptoms) and on respondents' characteristics such as age, education, and gender. The results are obtained by comparing two cities, one with a high rate of pollution due to oil extraction, Atyrau, and the other, Astana, without. The incremental health costs for Atyrau caused by the oil production industry are estimated to be at least 5.1 million USD per year. The annual benefits of investments into abatement technologies are at least five times higher than the virtual annual abatement costs of about 0.46 million USD

Estimating the National Carbon Abatement Potential of City Policies: A Data- Driven Approach

Energy Technology Data Exchange (ETDEWEB)

2016-10-01

Cities are increasingly taking actions such as building code enforcement, urban planning, and public transit expansion to reduce emissions of carbon dioxide in their communities and municipal operations. However, many cities lack the quantitative information needed to estimate policy impacts and prioritize city actions in terms of carbon abatement potential and cost effectiveness. This report fills this research gap by providing methodologies to assess the carbon abatement potential of a variety of city actions. The methodologies are applied to an energy use data set of 23,458 cities compiled for the U.S. Department of Energy’s City Energy Profile tool. The analysis estimates the national carbon abatement potential of the most commonly implemented actions in six specific policy areas. The results of this analysis suggest that, in aggregate, cities could reduce nationwide carbon emissions by about 210 million metric tons of carbon dioxide (MMT CO₂) per year in a "moderate abatement scenario" by 2035 and 480 MMT CO₂/year in a "high abatement scenario" by 2035 through these common actions typically within a city’s control in the six policy areas. The aggregate carbon abatement potential of these specific areas equates to a reduction of 3%-7% relative to 2013 U.S. emissions. At the city level, the results suggest the average city could reduce carbon emissions by 7% (moderate) to 19% (high) relative to current city-level emissions. City carbon abatement potential is sensitive to national and state policies that affect the carbon intensity of electricity and transportation. Specifically, the U.S. Clean Power Plan and further renewable energy cost reductions could reduce city carbon emissions overall, helping cities achieve their carbon reduction goals.

Emission abatement: Untangling the impacts of the EU ETS and the economic crisis

International Nuclear Information System (INIS)

Bel, Germà; Joseph, Stephan

2015-01-01

In this study we use historical emission data from installations under the European Union Emissions Trading System (EU ETS) to evaluate the impact of this policy on greenhouse gas emissions during the first two trading phases (2005–2012). As such the analysis seeks to disentangle two causes of emission abatement: that attributable to the EU ETS and that attributable to the economic crisis that hit the EU in 2008/09. To do so, we use a dynamic panel data approach. Our results suggest that, by far, the biggest share of abatement was attributable to the effects of the economic crisis. This finding has serious implications for future policy adjustments affecting core elements of the EU ETS, including the distribution of EU emission allowances. - Highlights: • We untangle the effects of the EU ETS from those of the economic crisis on industrial emission abatement. • The empirical analysis uses verified emission data instead of estimated emission data. • Abatement of emissions in EU in the last years has been mainly due to the impact of the economic crisis. • Low level of abatement attributable to the EU ETS suggests that important changes must be made in environmental policy

NASA is transforming human spaceflight. The Agency is shifting from an exploration-based program with human activities in low Earth orbit (LEO) and targeted robotic missions in deep space to a more sustainable and integrated pioneering approach. Through pioneering, NASA seeks to address national goals to develop the capacity for people to work, learn, operate, live, and thrive safely beyond Earth for extended periods of time. However, pioneering space involves daunting technical challenges of transportation, maintaining health, and enabling crew productivity for long durations in remote, hostile, and alien environments. Prudent investments in capability and technology developments, based on mission need, are critical for enabling a campaign of human exploration missions. There are a wide variety of capabilities and technologies that could enable these missions, so it is a major challenge for NASA's Human Exploration and Operations Mission Directorate (HEOMD) to make knowledgeable portfolio decisions. It is critical for this pioneering initiative that these investment decisions are informed with a prioritization process that is robust and defensible. It is NASA's role to invest in targeted technologies and capabilities that would enable exploration missions even though specific requirements have not been identified. To inform these investments decisions, NASA's HEOMD has supported a variety of analysis activities that prioritize capabilities and technologies. These activities are often based on input from subject matter experts within the NASA community who understand the technical challenges of enabling human exploration missions. This paper will review a variety of processes and methods that NASA has used to prioritize and rank capabilities and technologies applicable to human space exploration. The paper will show the similarities in the various processes and showcase instances were customer specified priorities force modifications to the process. Specifically

Marginal abatement cost curves in general equilibrium: The influence of world energy prices

International Nuclear Information System (INIS)

Klepper, Gernot; Peterson, Sonja

2006-01-01

Marginal abatement cost curves (MACCs) are a favorite instrument to analyze international emissions trading. This paper focuses on the question of how to define MACCs in a general equilibrium context where the global abatement level influences energy prices and in turn national MACCs. We discuss the mechanisms theoretically and then use the CGE model DART for quantitative simulations. The result is, that changes in energy prices resulting from different global abatement levels do indeed affect national MACCs. Also, we compare different possibilities of defining MACCs-of which some are robust against changes in energy prices while others vary considerably. (author)

Direct crowding out, optimal taxation and pollution abatement

Energy Technology Data Exchange (ETDEWEB)

Van der Ploeg, Frederick [FEE, University of Amsterdam, Amsterdam (Netherlands); Bovenberg, A. Lans [CentER, Tilburg University, Tilburg (Netherlands)

1993-05-01

The interactions between direct crowding out, the provision of public goods, optimal taxation and environmental policy are explored. Greener preferences induce a larger tax rate by raising the non-distortionary level of the tax rate. If the marginal productivity of public abatement diminishes rapidly environmental quality improves mainly through a fall in economic activity and emissions. In this case, public consumption increases which crowds out labour supply and private consumption. However, if environmental policy is very effective public consumption falls in order to make room for public abatement. In this case, if labour supply is inelastic with respect to the after-tax wage and direct crowding in is strong, labour supply and economic activity may expand. 1 fig., 7 refs.

How large a carbon tax is justified by the secondary benefits of CO2 abatement?

International Nuclear Information System (INIS)

Ekins, Paul

1996-01-01

The combustion of fossil fuels emits a range of damaging pollutants, the emissions of which are reduced if fossil fuel use is reduced in order to achieve CO 2 abatement. These reductions are termed the secondary benefits of such abatement. The paper reviews estimates of the size of these benefits at current levels of emissions of the relevant pollutants. Although the estimates are few and uncertain, their mid-range suggests that the secondary benefits are of the same order of magnitude as the gross costs of medium to high levels of CO 2 abatement, and are substantially larger than the (equally uncertain) estimates of the primary benefits of CO 2 abatement, except where these benefits derive from consideration of damages from unabated global warming in the very long term. The paper then reviews these calculations in the light of the limits on SO 2 emissions mandated by the Second Sulphur Protocol (SSP). It finds that the secondary benefits from abating SO 2 alone beyond the limits of the SSP still provide a substantial offset to the costs of a carbon tax. The paper concludes that the existence of significant secondary benefits greatly reinforces the economic case for an aggressive policy of CO 2 abatement

Working Group 'Air pollution abatement' of the University of Stuttgart -ALS. Annual report 1990

1991-01-01

Despite considerable efforts for air pollution abatement - examples are here desulphurization and nitrogen removal in power and large combustion plants as well as catalytic converters for automobiles there are still many problems to solve. Many small and medium-size companies still have to reduce production-related pollutant emissions, traffic still is a major source of pollutants. Air pollution abatement in the new Federal states and other Eastern European countries is a particularly urgent task and reductions of CO 2 emissions from energy production processes with fossil fuels are not least a great challenge. Apart from industry, legislation and administration especially science is called upon to find solutions to these problems. The university of Stuttgart takes up the challenge. Numerous institutes - 17 of 8 faculties -united in the working group ''air pollution abatement'' of the university of Stuttgart which carries out in interdisciplinary cooperation research work in the area of air pollution abatement. In this annual report activities of individual member states institutes in the area of air pollution abatement (fields of study, current research projects, cooperations and publications in 1991) as well as joint projects are presented.

Marginal abatement cost curves for policy recommendation – A method for energy system analysis

International Nuclear Information System (INIS)

Tomaschek, Jan

2015-01-01

The transport sector is seen as one of the key factors for driving future energy consumption and greenhouse gas (GHG) emissions. In order to rank possible measures marginal abatement cost curves have become a tool to graphically represent the relationship between abatement costs and emission reduction. This paper demonstrates how to derive marginal abatement cost curves for well-to-wheel GHG emissions of the transport sector considering the full energy provision chain and the interlinkages and interdependencies within the energy system. Presented marginal abatement cost curves visualize substitution effects between measures for different marginal mitigation costs. The analysis makes use of an application of the energy system model generator TIMES for South Africa (TIMES-GEECO). For the example of Gauteng province, this study exemplary shows that the transport sector is not the first sector to address for cost-efficient reduction of GHG emissions. However, the analysis also demonstrates that several options are available to mitigate transport related GHG emissions at comparable low marginal abatement costs. This methodology can be transferred to other economic sectors as well as to other regions in the world to derive cost-efficient GHG reduction strategies

The capability for living off the land, commonly called in-situ resource utilization, is finally gaining traction in space exploration architectures. Production of oxygen from the Martian atmosphere is called an enabling technology for human return from Mars, and a flight demonstration to be flown on the Mars 2020 robotic lander is in development. However, many of the individual components still require technical improvements, and system-level trades will be required to identify the best combination of technology options. Based largely on work performed for two recent roadmap activities, this paper defines the capability and technology requirements that will need to be achieved before this game-changing capability can reach its full potential.

Relative Greenhouse Gas Abatement Cost Competitiveness of Biofuels in Germany

Directory of Open Access Journals (Sweden)

Markus Millinger

2018-03-01

Full Text Available Transport biofuels derived from biogenic material are used for substituting fossil fuels, thereby abating greenhouse gas (GHG emissions. Numerous competing conversion options exist to produce biofuels, with differing GHG emissions and costs. In this paper, the analysis and modeling of the long-term development of GHG abatement and relative GHG abatement cost competitiveness between crop-based biofuels in Germany are carried out. Presently dominant conventional biofuels and advanced liquid biofuels were found not to be competitive compared to the substantially higher yielding options available: sugar beet-based ethanol for the short- to medium-term least-cost option and substitute natural gas (SNG for the medium to long term. The competitiveness of SNG was found to depend highly on the emissions development of the power mix. Silage maize-based biomethane was found competitive on a land area basis, but not on an energetic basis. Due to land limitations, as well as cost and GHG uncertainty, a stronger focus on the land use of crop-based biofuels should be laid out in policy.

Potential of electric discharge plasma methods in abatement of volatile organic compounds originating from the food industry.

Science.gov (United States)

Preis, S; Klauson, D; Gregor, A

2013-01-15

Increased volatile organic compounds emissions and commensurate tightening of applicable legislation mean that the development and application of effective, cost-efficient abatement methods are areas of growing concern. This paper reviews the last two decades' publications on organic vapour emissions from food processing, their sources, impacts and treatment methods. An overview of the latest developments in conventional air treatment methods is presented, followed by the main focus of the paper, non-thermal plasma technology. The results of the review suggest that non-thermal plasma technology, in its pulsed corona discharge configuration, is an emerging treatment method with potential for low-cost, effective abatement of a wide spectrum of organic air pollutants. It is found that the combination of plasma treatment with catalysis is a development trend that demonstrates considerable potential. The as yet relatively small number of plasma treatment applications is considered to be due to the novelty of pulsed electric discharge techniques and a lack of reliable pulse generators and reactors. Other issues acting as barriers to widespread adoption of the technique include the possible formation of stable oxidation by-products, residual ozone and nitrogen oxides, and sensitivity towards air humidity.

About half of all people with disabilities in developing countries live in extreme poverty. Focusing on the ends rather than the economic means of human development, the capability approach offers an alternative view of poverty. The purpose of this study was to explore the relation between assistive technology use and capability poverty in a low-income country. Self-reported data on food intake, health care, education, politics, self-determination, self-respect, family relationships and friendships were collected in Bangladesh through interviews of people with hearing impairments using and not using hearings aids, and people with ambulatory impairments using and not using manual wheelchairs (N = 583). Differences in outcomes between users and non-users of assistive technology were analyzed using logistic regression. Assistive technology users were more likely than non-users to report enhanced capabilities, hearing aid users to a larger extent than wheelchair users. Synergistic effects between assistive technology use and education were found. The use of assistive technology is predictive of reduced capability poverty in Bangladesh. Lack of wheelchair accessibility and the nature of selected outcomes may explain the limited association in the ambulatory group. Enhancing the effects of the other, there is support for providing education in combination with hearing aids. [Box: see text].

Benefits from restoring wetlands for nitrogen abatement: A case study of Gotland

International Nuclear Information System (INIS)

Gren, I.M.

1992-01-01

The values of nitrogen abatement by measures involving restoration of wetlands, sewage treatment plants and agriculture are calculated and compared. The analytical results show that the value of wetlands is likely to exceed the values of other measures due to the multi-functionality of wetlands and their self-organizing ability. The multi-functionality implies that, in addition to nitrogen abatement, other outputs like buffering of water and biodiversity are produced and the self-organizing feature reduces the rate at which future values of outputs are discounted. According to the empirical results applied to Gotland, a Swedish island in the Baltic with high concentrations of nitrate in the ground water, the imputed value of wetlands exceeds the corresponding values of the other nitrogen abatement measures by several hundred per cent. 21 refs, 6 tabs

Design and Research on Platform to Enhance College Students’ Art Appreciation Capability Based on Modern Information Technology

Directory of Open Access Journals (Sweden)

2015-01-01

Full Text Available Nowadays, with the rapid development of modern information technology, the college students could not preferably choose and learn to enhance their own art appreciation capability. Therefore, the colleges and universities have a more urgent desire to organize, develop and provide a good platform to enhance the college students’ art appreciation capability based on modern information technology. This paper describes how to enhance the art appreciation capability in detail, and designs and analyzes the platform to enhance college students’ art appreciation capability based on modern information technology---the “Music Corner” and the “Dance Corner”, indicating that the exchange platform built with modern information technology can promotes the college students’ art appreciation capability. Finally, through the analysis of statistical results of the questionnaire, college students are fonder of art appreciation after the establishment of platform, more inclined to the comprehensive learning of art, more brave to express their own sense of art, and fonder of artistic creation.

Elzen, Michel G.J. den; Hof, Andries F.; Mendoza Beltran, Angelica; Grassi, Giacomo; Roelfsema, Mark; Ruijven, Bas van; Vliet, Jasper van; Vuuren, Detlef P. van

2011-01-01

As part of the Copenhagen Accord, individual countries have submitted greenhouse gas reduction proposals for the year 2020. This paper analyses the implications for emission reductions, the carbon price, and abatement costs of these submissions. The submissions of the Annex I (industrialised) countries are estimated to lead to a total reduction target of 12-18% below 1990 levels. The submissions of the seven major emerging economies are estimated to lead to an 11-14% reduction below baseline emissions, depending on international (financial) support. Global abatement costs in 2020 are estimated at about USD 60-100 billion, assuming that at least two-thirds of Annex I emission reduction targets need to be achieved domestically. The largest share of these costs are incurred by Annex I countries, although the costs as share of GDP are similar for Annex I as a group and the seven emerging economies as a group, even when assuming substantial international transfers from Annex I countries to the emerging economies to finance their abatement costs. If the restriction of achieving two-thirds of the emission reduction target domestically is abandoned, it would more than double the international carbon price and at the same time reduce global abatement costs by almost 25%.

This report presents the results of a technical and economic assessment of available alternatives for asbestos abatement within Facility 20470 at the Wright-Patterson Air Force Base in Dayton, Ohio. Each alternative was screened on the basis of technical feasibility, environmental impact, economics, and fulfillment of the IRP goals.

Mosquito abatement programs in Midwestern communities frequently exist within landscapes dominated by agriculture. Although separately managed, both agricultural pests and mosquitoes are targeted by similar classes of insecticides. As a result, there is the potential for unintended insecticide exposure to mosquito populations from agricultural pest management. To determine the impact that agricultural management practices have on mosquito insecticide susceptibility we compared the mortality of Aedes vexans (Meigen; Diptera: Culicidae) between populations sampled from locations with and without mosquito abatement in South Dakota, a region dominated by agricultural production. Collection locations were either within towns with mosquito abatement programs (n = 2; Brookings and Sioux Falls, SD) or located > 16 km from towns with mosquito abatement programs (n = 2; areas near Harrold and Willow Lake, SD). WHO bioassays were used to test susceptibly of adults to differing insecticide classes relative to their respective controls; 1) an organochlorine (dieldrin 4%), 2) an organophosphate (malathion 5%), and 3) a pyrethroid (lambda-cyhalothrin 0.05%). Corrected mortality did not significantly differ between locations with or without abatement; however, when locations were analized by proportion of developed land within the surrounding landscape pyrethroid mortality was significantly lower where crop production dominated the surrounding landscape and mosquito abatement was present. These data suggest that agricultural pest management may incidentally contribute to reduced mosquito susceptibility where overlap between agricultural pest management and mosquito abatement exists. Decoupling insecticide classes used by both agricultural and public health pest management programs may be necessary to ensure continued efficacy of pest management tools.

Inefficient national environmental regulation as a signal of high abatement costs

Energy Technology Data Exchange (ETDEWEB)

Steiner, U.

1997-12-31

This paper analyses the importance of informational asymmetries in international environmental regulation by use of a game theoretic approach of signaling games. More specific it analysis whether it is possible for a government to try to extract higher compensation in an international unidirectoral environmental problem. This may be possible when the national environmental regulation carries a signal of the cost of the regulated industry. In this case the government e.g. by means of inefficient environmental regulation on a national level may try to signal high abatement costs. In spite of the fact that many international environmental problems seem to be solvable by the use of financial payments there are only few examples that compensation payment arrangements have been implemented. As many countries and especially many polluting firms possess better information about abatement costs than the countries that receive the pollution, it is worthwhile to include asymmetric information. Consequently, this paper analyses whether the introduction of asymmetric information about abatement costs may bring forward incentives to misrepresent the true abatement cost in order to capture more compensation. If these incentives turn out to be present, it may explain some of the suspicion against using financial payment in order to induce other countries to join an agreement. The analysis shows that it may indeed be the case that the expected gain from cheating is so large that it gives incentives to use an inefficient national environmental policy. (au) 13 refs.

The value of international cooperation for abating global climate change

International Nuclear Information System (INIS)

Hammitt, James K.; Adams, John L.

1996-01-01

Because abatement of global climate change is a public good, independent national actions may not produce the efficient quantity. Using a numerical integrated-assessment model, abatement costs and damages induced by climate change are compared at the cooperative and noncooperative solutions to a set of two-party dynamic games between the industrialized and developing countries. Games with perfect and imperfect information about climate and economic factors are considered. Across 144 games with perfect information, incorporating different values of climate and economic parameters, the noncooperative solution usually yields global benefits comparable to those of the cooperative solution. In about one-fifth of these games, however, a second noncooperative solution exists which yields none of the benefits of the cooperative solution. In a game with imperfect information, where the state of nature is uncertain in the first but known in the second of two periods, the expected benefits of the noncooperative solution are 98% of the expected benefits of the cooperative solution. In contrast to single-agent studies which show little cost to delaying abatement, the benefits of cooperation are usually lost if cooperation is delayed 20 years

The surface soil on sewage outfall and effluent of farmer household septic tank were collected in situ from the typical region of plain river network areas in Taihu Lake Basin, and the typical rainfall (summer 30 mm . times-1, winter 5 mm times -1), temperature (summer 27 degrees C, winter 5 degrees C ) condition and pollutant load were artificial simulated by indoor simulation soil column experiments for estimating nitrogen abatement rate of rural sewage treated by the outfall soil and exploring the abatement rule in different seasons and weather process (7 days before the rain, 3 rainy days, 7 days after the rain). Results showed that: there was the significant difference (P 0. 05). Therefore, the TN, NH+4 -N abatement rate, NO-3 -N increase rate need to be divided by seasons, TN abatement rate, NO-3 -N increase rate of summer need to be divided by the weather process, which were 38.5% , - 25.0% , 46. 0% and 478. 1%, 913.8%, 382. 0% , before the rain, in rainy day, after the rain, respectively; while the NH+4 -N abatement rate of summer and the TN, NH+4 -N abatement rate, NO-3 -N increase rate of winter do not need to be divided by weather process, were 91.7% , 50.4% , 85.5% and 276.0% , respectively. In the summer, the TN abatement rate in different weather processes was not correlated with NH+4 -N abatement rate, but significantly negative correlated with NO-3 -N increase rate. In the winter, the stable accumulation of TN in soil was an important reason of the TN abatement rate which had no significant difference and kept a high level among different weather processes, and it was closely related to the stable accumulation of NH+4 -N in soil.

Greenhouse Gas and Ammonia Emissions from Different Stages of Liquid Manure Management Chains: Abatement Options and Emission Interactions.

Science.gov (United States)

Mohankumar Sajeev, Erangu Purath; Winiwarter, Wilfried; Amon, Barbara

2018-01-01

Farm livestock manure is an important source of ammonia and greenhouse gases. Concerns over the environmental impact of emissions from manure management have resulted in research efforts focusing on emission abatement. However, questions regarding the successful abatement of manure-related emissions remain. This study uses a meta-analytical approach comprising 89 peer-reviewed studies to quantify emission reduction potentials of abatement options for liquid manure management chains from cattle and pigs. Analyses of emission reductions highlight the importance of accounting for interactions between emissions. Only three out of the eight abatement options considered (frequent removal of manure, anaerobic digesters, and manure acidification) reduced ammonia (3-60%), nitrous oxide (21-55%), and methane (29-74%) emissions simultaneously, whereas in all other cases, tradeoffs were identified. The results demonstrate that a shift from single-stage emission abatement options towards a whole-chain perspective is vital in reducing overall emissions along the manure management chain. The study also identifies some key elements like proper clustering, reporting of influencing factors, and explicitly describing assumptions associated with abatement options that can reduce variability in emission reduction estimates. Prioritization of abatement options according to their functioning can help to determine low-risk emission reduction options, specifically options that alter manure characteristics (e.g., reduced protein diets, anaerobic digestion, or slurry acidification). These insights supported by comprehensive emission measurement studies can help improve the effectiveness of emission abatement and harmonize strategies aimed at reducing air pollution and climate change simultaneously.

The differential impact of low-carbon technologies on climate change mitigation cost under a range of socioeconomic and climate policy scenarios

International Nuclear Information System (INIS)

Barron, Robert; McJeon, Haewon

2015-01-01

This paper considers the effect of several key parameters of low carbon energy technologies on the cost of abatement. A methodology for determining the minimum level of performance required for a parameter to have a statistically significant impact on CO 2 abatement cost is developed and used to evaluate the impact of eight key parameters of low carbon energy supply technologies on the cost of CO 2 abatement. The capital cost of nuclear technology is found to have the greatest impact of the parameters studied. The cost of biomass and CCS technologies also have impacts, while their efficiencies have little, if any. Sensitivity analysis of the results with respect to population, GDP, and CO 2 emission constraint show that the minimum performance level and impact of nuclear technologies is consistent across the socioeconomic scenarios studied, while the other technology parameters show different performance under higher population, lower GDP scenarios. Solar technology was found to have a small impact, and then only at very low costs. These results indicate that the cost of nuclear is the single most important driver of abatement cost, and that trading efficiency for cost may make biomass and CCS technologies more competitive. - Highlights: • The impact of low carbon energy technology on abatement cost is considered. • Nuclear has the largest impact among technologies considered. • Cost has higher impact than efficiency for biomass technologies. • Biomass technologies generally have larger impacts than carbon capture. • Biomass technologies are more valuable in low GDP, high population scenarios

Pollution Emissions, Environmental Policy, and Marginal Abatement Costs.

Pollution emissions impose serious social negative externalities, especially in terms of public health. To reduce pollution emissions cost-effectively, the marginal abatement costs (MACs) of pollution emissions must be determined. Since the industrial sectors are the essential pillars of China's economic growth, as well as leading energy consumers and sulfur dioxide (SO₂) emitters, estimating MACs of SO₂ emissions at the industrial level can provide valuable information for all abatement efforts. This paper tries to address the critical and essential issue in pollution abatement: How do we determine the MACs of pollution emissions in China? This paper first quantifies the SO₂ emission contribution of different industrial sectors in the Chinese economy by an Input-Output method and then estimates MACs of SO₂ for industrial sectors at the national level, provincial level, and sectoral level by the shadow price theory. Our results show that six sectors (e.g., the Mining and Washing of Coal sector) should be covered in the Chinese pollution emission trading system. We have also found that the lowest SO₂ shadow price is 2000 Yuan/ton at the national level, and that shadow prices should be set differently at the provincial level. Our empirical study has several important policy implications, e.g., the estimated MACs may be used as a pricing benchmark through emission allowance allocation. In this paper, the MACs of industrial sectors are calculated from the national, provincial and sectoral levels; therefore, we provide an efficient framework to track the complex relationship between sectors and provinces.

Change, technology and higher education: are universities capable of organisational change?

Directory of Open Access Journals (Sweden)

Stephen Marshall

2010-12-01

Full Text Available Technology and change are so closely related that the use of the word innovation seems synonymous with technology in many contexts, including that of higher education. This paper contends that university culture and existing capability constrain such innovation and to a large extent determine the nature and extent of organisational change. In the absence of strong leadership, technologies are simply used as vehicles to enable changes that are already intended or which reinforce the current identity. These contentions are supported by evidence from e-learning benchmarking activities carried out over the past five years in universities in the United States, the United Kingdom, Australia and New Zealand.

Abatement of mercury pollution in the small-scale gold mining industry: restructuring the policy and research agendas.

Science.gov (United States)

Hilson, Gavin

2006-06-01

This paper critiques contemporary research and policy approaches taken toward the analysis and abatement of mercury pollution in the small-scale gold mining sector. Unmonitored releases of mercury from gold amalgamation have caused considerable environmental contamination and human health complications in rural reaches of sub-Saharan Africa, Latin America and Asia. Whilst these problems have caught the attention of the scientific community over the past 15-20 years, the research that has since been undertaken has failed to identify appropriate mitigation measures, and has done little to advance understanding of why contamination persists. Moreover, the strategies used to educate operators about the impacts of acute mercury exposure, and the technologies implemented to prevent further pollution, have been marginally effective at best. The mercury pollution problem will not be resolved until governments and donor agencies commit to carrying out research aimed at improving understanding of the dynamics of small scale gold mining communities. Acquisition of this knowledge is the key to designing and implementing appropriate support and abatement measures.

Valuation of marginal CO2 abatement options for electric power plants in Korea

International Nuclear Information System (INIS)

Park, Hojeong; Lim, Jaekyu

2009-01-01

The electricity generation sector in Korea is under pressure to mitigate greenhouse gases as directed by the Kyoto Protocol. The principal compliance options for power companies under the cap-and-trade include the application of direct CO 2 emission abatement and the procurement of emission allowances. The objective of this paper is to provide an analytical framework for assessing the cost-effectiveness of these options. We attempt to derive the marginal abatement cost for CO 2 using the output distance function and analyze the relative advantages of emission allowance procurement option as compared to direct abatement option. Real-option approach is adopted to incorporate emission allowance price uncertainty. Empirical result shows the marginal abatement cost with an average of Euro 14.04/ton CO 2 for fossil-fueled power plants and confirms the existence of substantial cost heterogeneity among plants which is sufficient to achieve trading gains in allowance market. The comparison of two options enables us to identify the optimal position of the compliance for each plant. Sensitivity analyses are also presented with regard to several key parameters including the initial allowance prices and interest rate. The result of this paper may help Korean power plants to prepare for upcoming regulations targeted toward the reduction of domestic greenhouse gases.

Photocatalytic NO_x abatement. Theory, applications, current research, and limitations

International Nuclear Information System (INIS)

Bloh, Jonathan Z.

2017-01-01

Nitrogen oxides are one of the major air pollutants that threaten our air quality and health. As a consequence, increasingly stricter regulations are in place forcing action to reduce the concentration of these dangerous compounds. Conventional methods of reducing the NO_x pollution level are reducing the emission directly at the source or restrictive measures such as low emission zones. However, there are recent reports questioning the efficacy of the strategy to reduce ambient NO_x levels solely by reducing their emissions and existing threshold values are still frequently exceeded in many European cities. Semiconductor photocatalysis presents an appealing alternative capable of removing NO_x and other air pollutants from the air once they have already been released and dispersed. Recent field tests have shown that a reduction of a few percent in NO_x values is possible with available photocatalysts. Current research focuses on further increasing the catalysts' efficacy as well as their selectivity to suppress the formation of undesired by-products. Especially using these improved materials, photocatalytic NO_x abatement could prove a very valuable contributor to better air quality.

Schneider, John E; Peterson, N Andrew; Kiss, Noemi; Ebeid, Omar; Doyle, Alexis S

2011-05-01

Growing concern over the costs, environmental impact and safety of tobacco product litter (TPL) has prompted states and cities to undertake a variety of policy initiatives, of which litter abatement fees are part. The present work describes a framework and methodology for calculating TPL costs and abatement fees. Abatement is associated with four categories of costs: (1) mechanical and manual abatement from streets, sidewalks and public places, (2) mechanical and manual abatement from storm water and sewer treatment systems, (3) the costs associated with harm to the ecosystem and harm to industries dependent on clean and healthy ecosystems, and (4) the costs associated with direct harm to human health. The experiences of the City of San Francisco's recently proposed tobacco litter abatement fee serve as a case study. City and municipal TPL costs are incurred through manual and mechanical clean-up of surfaces and catchment areas. According to some studies, public litter abatement costs to US cities range from US$3 million to US$16 million. TPL typically comprises between 22% and 36% of all visible litter, implying that total public TPL direct abatement costs range from about US$0.5 million to US$6 million for a city the size of San Francisco. The costs of mitigating the negative externalities of TPL in a city the size of San Francisco can be offset by implementing a fee of approximately US$0.20 per pack. Tobacco litter abatement costs to cities can be substantial, even when the costs of potential environmental pollution and tourism effects are excluded. One public policy option to address tobacco litter is levying of fees on cigarettes sold. The methodology described here for calculating TPL costs and abatement fees may be useful to state and local authorities who are considering adoption of this policy initiative.

CO2 Abatement In The Iron And Steel Industry

Energy Technology Data Exchange (ETDEWEB)

NONE

2012-01-15

The iron and steel industry is the largest industrial source of CO2 emissions due to the energy intensity of steel production, its reliance on carbon-based fuels and reductants, and the large volume of steel produced -- over 1414 Mt in 2010. With the growing concern over climate change, steel makers are faced with the challenge of finding ways of lowering CO2 emissions without seriously undermining process efficiency or considerably adding to costs. This report examines ways of abating CO2 emissions from raw materials preparation (coking, sintering and pelletising plants) through to the production of liquid steel in basic oxygen furnaces and electric arc furnaces. Direct reduction and smelting reduction processes are covered, as well as iron making in a blast furnace. A range of technologies and measures exist for lowering CO2 emissions including minimising energy consumption and improving energy efficiency, changing to a fuel and/or reducing agent with a lower CO2 emission factor (such as wood charcoal), and capturing the CO2 and storing it underground. Significant CO2 reductions can be achieved by combining a number of the available technologies. If carbon capture and storage is fitted than steel plants could become near zero emitters of CO2.

In order to comply with the European Union's ambient air quality standards, the Netherlands must reduce emissions of PM10. As a contributor to PM10, the poultry industry must implement mitigation measures before 2012. An extensive research and development program was launched in 2008 to provide abatement technology for broiler and layer houses. This paper presented results from studies carried out in 2008 and 2009 by Wageningen UR Livestock Research. The supply industry and poultry farmers participated in the study in which different methods and approaches were examined, including bedding material, light schedules, oil spraying systems, ionization systems, water scrubbers, combined scrubbers, electrostatic filters, and dry filters. Most methods were first tested and optimized in small units at an experimental poultry facility Lelystad. Several methods were validated in a next step on poultry farms, where PM10 emissions were measured to establish official emission factors. The oil spraying system and ionization system were tested in broiler houses and are nearing implementation. Reductions in PM10 emissions by different methods ranged from no effect to levels of 60 per cent. An outlook on adequate dust abatement measures for poultry housings was also provided.

The IOC-UNEP Regional Workshop to Review Priorities for Marine Pollution Monitoring, Research, Control and Abatement in the Wider Caribbean Region (San Jose, 24-30 August 1989) examined a possible general framework for a regionally co-ordinated comprehensive joint IOC/UNEP programme for marine pollution assessment and control in the Wider Caribbean region (CEPPOL). The overall objective of CEPPOL is to establish a regionally co-ordinated comprehensive joint IOC/UNEP Marine Pollution Assessment and Control Programme catering to the immediate and long-term requirements of the Cartagena Convention as well as the requirements of the member States of IOCARIBE. The specific objectives of the programmes are: (i) To organize and carry out a regionally co-ordinated marine pollution monitoring and research programme concentrating on contaminants and pollutants affecting the quality of the marine and coastal environment, as well as the human health in the Wider Caribbean and to interpret/assess the results of the programme as part of the scientific basis for the region; (ii) To generate information on the sources, levels, amounts, trends and effects of marine pollution within the Wider Caribbean region as an additional component of the scientific basis upon which the formulation of proposals for preventive and remedial actions can be based; (iii) To formulate proposals for technical, administrative and legal pollution control, abatement, and preventive measures and to assist the Governments in the region in implementing and evaluating their effectiveness; and (iv) To strengthen and , when necessary, to develop/establish the capabilities of national institutions to carry out marine pollution monitoring and research, as well as to formulate and apply pollution control and abatement measures

Sustainable gasification–biochar systems? A case-study of rice-husk gasification in Cambodia, Part II: Field trial results, carbon abatement, economic assessment and conclusions

2012-01-01

In part I we described the gasification technology and characterised the physio-chemical properties and environmental impacts of the rice husk char (RHC) by-product. In part II we present summary results from field trials using the RHC, and provide an estimate of the carbon abatement and economic evaluation of the system. Statistically significant yield increases are demonstrated for RHC addition in irrigated rice cultivation (33% increase in paddy rice yield for a 41.5 t (dry weight) RHC application per hectare). The carbon abatement from the RHC addition is approximately 0.42 t CO 2 t −1 rice husk; including energy generation from gasification this increases to ca. 0.86 tCO 2 t −1 . Assuming a carbon value of $5 t CO 2 t −1 , and agronomic value of $3 t −1 RHC based on the field trials, the economic value of the RHC varies from $9 t −1 (including only recalcitrant carbon) to $15 t −1 (including avoided emissions from energy production). We summarise results from parts I and II, concluding that the gasification–biochar system meets many of the criteria of sustainability, but requires better waste water management and more field trials to demonstrate repeatable agronomic efficacy of RHC application. - Highlights: ► Field trials show statistically significant rice yield increases using rice husk char (RHC). ► Carbon abatement of 0.42 t CO 2 t −1 rice husk from RHC production. ► Bioenergy generation via gasification gives carbon abatement of 0.44 t CO 2 t −1 husk. ► Total carbon abatement is therefore ca. 0.86 t CO 2 t −1 husk. ► Agronomic value from trials is $3 t −1 char; assuming $5 CO 2 t −1 , the total value of RHC is $9–$15 t −1 .

Collateral benefits and hidden hazards of soil arsenic during abatement assessment of residential lead hazards

2008-01-01

Abatement of soil-lead hazards may also reduce human exposure to other soil toxins, thereby achieving significant collateral benefits that are not accounted for today. This proposition was tested with the specific case of soil-arsenic, where 1726 residential soil samples were collected and analyzed for lead and arsenic. The study found that these two toxins coexisted in most samples, but their concentrations were weakly correlated, reflecting the differing sources for each toxin. Collateral benefits of 9% would be achieved during abatement of the lead-contaminated soils having elevated arsenic concentrations. However, a hidden hazard of 16% was observed by overlooking elevated arsenic concentrations in soils having lead concentrations not requiring abatement. This study recommends that soil samples collected under HUD programs should be collected from areas of lead and arsenic deposition and tested for arsenic as well as lead, and that soil abatement decisions consider soil-arsenic as well as soil-lead guidelines. - Coexistence of arsenic at elevated concentrations with lead in residential soils undergoing lead hazard assessment is often overlooked, providing either collateral benefits or hidden hazards

Ongel, Aybike; Sezgin, Fatih

2016-01-01

In recent decades, noise pollution caused by industrialization and increased motorization has become a major concern around the world because of its adverse effects on human well-being. Therefore, transportation agencies have been implementing noise abatement measures in order to reduce road traffic noise. However, limited attention is given to noise in environmental assessment of road transportation systems. This paper presents a framework for a health impact assessment model for road transportation noise emissions. The model allows noise impacts to be addressed with the health effects of air pollutant and greenhouse gas emissions from road transportation. The health damages assessed in the model include annoyance, sleep disturbance, and cardiovascular disease in terms of acute myocardial infarction. The model was applied in a case study in Istanbul in order to evaluate the change in health risks from the implementation of noise abatement strategies. The noise abatement strategies evaluated include altering pavement surfaces in order to absorb noise and introducing speed limits. It was shown that significant improvements in health risks can be achieved using open graded pavement surfaces and introducing speed limits on highways. - Highlights: • Transportation noise has a significant effect on health. • Noise should be included in the environmental assessment of transportation systems. • Traffic noise abatement measures include noise reducing pavements and speed limits. • Noise abatement measures help reduce the health risks of transportation noise. • Speed limit reduction on uncongested roads is an effective way to reduce health risks.

Full Text Available The study examines whether or not and how information technology (IT relatedness influences corporate performance. This study proposes that knowledge management (KM is a critical organizational capability through which IT influences firm performance. Measurement of IT relatedness and KM capability uses a reflective second-order factor modeling approach for capturing complementarities among the four dimensions of IT relatedness (IT strategy making processes, IT vendor management processes, IT human resource management processes and IT infrastructure and for capturing complementarities among the three dimensions of KM capability (product KM capability, customer KM capability, and managerial KM capability. A survey was conducted among 93 branch managers of banking in Central Java. Structural Equation Model (SEM was used to analyze the data using the software program of SmartPLS (Partial Least Square. The findings support for the hypotheses of the study. IT relatedness of business units enhances the cross unit KM capability of the corporate. The KM capability creates and exploits cross-unit synergies from the product, customer, and managerial knowledge resources of the corporate. These synergies increase the corporate performance. IT relatedness of business units positively influences corporate performance. IT relatedness also has significant indirect effects on corporate performance through the mediation of KM capability.

Reaping the carbon rent: Abatement and overallocation profits in the European cement industry, insights from an LMDI decomposition analysis

International Nuclear Information System (INIS)

Branger, Frédéric; Quirion, Philippe

2015-01-01

We analyse variations of carbon emissions in the European cement industry from 1990 to 2012, at the European level (EU 27), and at the national level for six major producers (Germany, France, Spain, the United Kingdom, Italy and Poland). We apply a Log-Mean Divisia Index (LMDI) method, cross-referencing data from three databases: the Getting the Numbers Right (GNR) database developed by the Cement Sustainability Initiative, the European Union Transaction Log (EUTL), and the Eurostat International Trade database. Our decomposition method allows seven channels of emission change to be distinguished: activity, clinker trade, clinker share, alternative fuels, thermal and electrical energy efficiency, and electricity decarbonisation. We find that, apart from a slow trend of emission reductions coming from technological improvements (first from a decrease in the clinker share, then from an increase in alternative fuels), most of the emission change can be attributed to the activity effect. Using counterfactual scenarios, we estimate that the introduction of the EU ETS brought small but positive technological abatement (2.2% ± 1.3% between 2005 and 2012). Moreover, we find that the European cement industry has gained 3.5 billion Euros of “overallocation profits”, mostly due to the slowdown of production. - Highlights: • We analyse variations of carbon emissions in the European cement industry. • We apply a Log-Mean Divisia Index (LMDI) method. • Most of the emission changes can be attributed to the activity effect. • The EU ETS brought small but positive technological abatement. • The European cement industry has gained 3.5 billion Euros of “overallocation profits”

The role of abatement costs in GHG permit allocations : a global reduction scenario with the World-MARKAL model

International Nuclear Information System (INIS)

Vaillancourt, K.; Kanudia, A.

2004-01-01

The World-MARKAL model was used to examine a permit trading system to stabilize greenhouse gas emissions. The model considered the participation of all countries, including developing countries. Allocation schemes aimed at fair distribution of net abatement costs among world regions were proposed. The net abatement costs for each region are good indicators of where more abatement measures are needed. Equity issues relative to permit allocations and burden sharing were also presented along with the allocation methodology. The gross abatement costs before permit trading were calculated for each region. The main advantages and disadvantages of this approach were listed. It was concluded that permit allocation schemes based on cost distribution make it possible to obtain solutions with equalized net costs per gross domestic product for all regions. 30 refs., 6 tabs., 3 figs

Abatement costs of soil conservation in China's Loess Plateau: balancing income with conservation in an agricultural system.

Hou, Lingling; Hoag, Dana L K; Keske, Catherine M H

2015-02-01

This study proposes the use of marginal abatement cost curves to calculate environmental damages of agricultural systems in China's Loess Plateau. Total system costs and revenues, management characteristics and pollution attributes are imputed into a directional output distance function, which is then used to determine shadow prices and abatement cost curves for soil and nitrogen loss. Marginal abatement costs curves are an effective way to compare economic and conservation tradeoffs when field-specific data are scarce. The results show that sustainable agricultural practices can balance soil conservation and agricultural production; land need not be retired, as is current policy. Published by Elsevier Ltd.

identify the supply-chain partner who provided the information prior to sharing this information with product tracing technology providers. The 9 traceability solution providers who agreed to participate in this project have their systems deployed in a wide range of sectors within the food industry including, but not limited to, livestock, dairy, produce, fruits, seafood, meat, and pork; as well as in pharmaceutical, automotive, retail, and other industries. Some have also been implemented across the globe including Canada, China, USA, Norway, and the EU, among others. This broad commercial use ensures that the findings of this work are applicable to a broad spectrum of the food system. Six of the 9 participants successfully completed the data entry phase of this test. To verify successful data entry for these 6, a demo or screenshots of the data set from each system's user interface was requested. Only 4 of the 6 were able to provide us with this evidence for verification. Of the 6 that completed data entry and moved on to the scenarios phase of the test, 5 were able to provide us with the responses to the scenarios. Time metrics were useful for evaluating the scalability and usability of each technology. Scalability was derived from the time it took to enter the nonstandardized data set into the system (ranges from 7 to 11 d). Usability was derived from the time it took to query the scenarios and provide the results (from a few hours to a week). The time was measured in days it took for the participants to respond after we supplied them all the information they would need to successfully execute each test/scenario. Two of the technology solution providers successfully implemented and participated in a proof-of-concept interoperable framework during Year 2 of this study. While not required, they also demonstrated this interoperability capability on the FSMA-mandated food product tracing pilots for the U.S. FDA. This has significant real-world impact since the

This program was undertaken to enhance the manufacturability, constructability, and cost of the Air2Air{TM} Water Conservation and Plume Abatement Cooling Tower, giving a validated cost basis and capability. Air2Air{TM} water conservation technology recovers a portion of the traditional cooling tower evaporate. The Condensing Module provides an air-to-air heat exchanger above the wet fill media, extracting the heat from the hot saturated moist air leaving in the cooling tower and condensing water. The rate of evaporate water recovery is typically 10% - 25% annually, depending on the cooling tower location (climate). This program improved the efficiency and cost of the Air2Air{TM} Water Conservation Cooling Tower capability, and led to the first commercial sale of the product, as described.

The synthesis of bottom-up and top-down approaches to climate policy modeling: Electric power technologies and the cost of limiting US CO2 emissions

International Nuclear Information System (INIS)

Wing, Ian Sue

2006-01-01

In the US, the bulk of CO 2 abatement induced by carbon taxes comes from electric power. This paper incorporates technology detail into the electricity sector of a computable general equilibrium model of the US economy to characterize electric power's technological margins of adjustment to carbon taxes and to elucidate their general equilibrium effects. Compared to the top-down production function representation of the electricity sector, the technology-rich hybrid specification produces less abatement at a higher welfare cost, suggesting that bottom-up models do not necessarily generate lower costs of abatement than top-down models. This result is shown to be sensitive to the elasticity with which technologies' generating capacities adjust to relative prices

NONE

2009-04-15

The document describes how the research, development and demonstration (RD&D) components of the United Kingdom Government's Carbon Abatement Technologies (CATs) Strategy should be developed and extended, with particular reference to a 2020 target for carbon dioxide capture and storage (CCS) commercialisation and the 2050 UK Committee on Climate Change (CCC) dioxide target. It sets out a strategy for RD&D through the establishment of a collaborative programme linking industry, and academia, and involving different funding sources. The proposed RD& D programme has seven strategic themes: Power plant: focus on cost, increasing efficiency, biomass co-firing; Capture technologies: focus on cost, efficiency penalty, waste heat utilisation; storage: focus on security, monitoring and verification; transport: focus on logistics and transport network; whole system: focus on risks, transient capability, economics, environmental issues; advanced and novel capture technologies; and underpinning technology support. 11 refs., 10 figs., 15 tabs.

Economic restructuring in Eastern Europe and acid rain abatement strategies

Amann, Markus; Klaassen, Ger; Schoepp, Wolfgang; Soerensen, Lene; Hordijk, Leen

1992-01-01

Acid rain abatement strategies in Europe are currently being discussed in view of the expiration of the Helsinki Protocol on SO 2 emission reduction. The changing energy situation in Eastern European countries is expected to have an influence on the deposition pattern in Europe. The paper presents a consistent energy scenario for Eastern European countries and compares optimal strategies to reduce SO 2 emissions. These strategies are based on runs with the RAINS model in which environmental targets have been set based on critical loads for sulphur. The analysis shows that economic restructuring and efficiency improvements in Eastern European countries, as well as in Western Europe, may result in significantly lower sulphur abatement costs. Potential assistance to Eastern Europe to guarantee desired environmental standards in Western countries should therefore focus not only on providing emission control devices but also on the success of the economic transition process.

2016-04-01

Full Text Available The paper analyzes the influence of management capabilities on the innovation performance of technology-based SMEs and the role that gender diversity in the top management team plays in this relationship. We use a sample of 205 Spanish SMEs from technology sectors and a hierarchical regression analysis to test our hypotheses. The results confirm that management capabilities affect both product and process innovation positively. In addition, gender diversity in the top management team moderates this relationship positively. In other words, management capabilities have a greater influence on both product and process innovation when the management team is more balanced in number of men and women. This study contributes to better understanding of the factors that explain how management capabilities translate into greater organizational achievements and argues the need to analyze the role of top management teams and their composition more extensively, especially in the context of technology SMEs. The study also contributes new evidence to the small number of studies that analyze the effect of gender diversity in top management teams on innovation.

Photocatalytic NO{sub x} abatement. Theory, applications, current research, and limitations

Energy Technology Data Exchange (ETDEWEB)

Bloh, Jonathan Z. [DECHEMA Research Institute, Frankfurt am Main (Germany)

2017-01-15

Nitrogen oxides are one of the major air pollutants that threaten our air quality and health. As a consequence, increasingly stricter regulations are in place forcing action to reduce the concentration of these dangerous compounds. Conventional methods of reducing the NO{sub x} pollution level are reducing the emission directly at the source or restrictive measures such as low emission zones. However, there are recent reports questioning the efficacy of the strategy to reduce ambient NO{sub x} levels solely by reducing their emissions and existing threshold values are still frequently exceeded in many European cities. Semiconductor photocatalysis presents an appealing alternative capable of removing NO{sub x} and other air pollutants from the air once they have already been released and dispersed. Recent field tests have shown that a reduction of a few percent in NO{sub x} values is possible with available photocatalysts. Current research focuses on further increasing the catalysts' efficacy as well as their selectivity to suppress the formation of undesired by-products. Especially using these improved materials, photocatalytic NO{sub x} abatement could prove a very valuable contributor to better air quality.

Emission trading and international competition: The impact of labor market rigidity on technology adoption and output

Caparrós, Alejandro; Péreau, Jean-Christophe; Tazdaït, Tarik

2013-01-01

Emission trading systems have been proposed in different regions to reduce polluting emissions and are in use in the European Union for carbon dioxide emissions. One of the objectives of these systems is to encourage firms to adopt advanced abatement technologies. However, permits also create an incentive to reduce output, which may be seen as negative by policy makers. We analyze the impact of a rigid labour market on these two outcomes, showing the conditions necessary to avoid reductions in production while keeping the incentives to improve abatement technologies. The analysis is done for oligopolistic firms engaged in international rivalry. - Highlights: ► Emission trading reduces production and improves abatement technologies. ► Policy makers see the first outcome as negative and the second as positive. ► This paper studies the impact of market rigidity on these two outcomes. ► It shows conditions to avoid the first outcome and maintain or enhance the second

Sustainable noise abatement along motorways in Germany – an empirical study in the municipality Frasdorf (Bavaria

Directory of Open Access Journals (Sweden)

Jürgen Breuste

2014-09-01

Full Text Available As part of the planned expansion work of the motorway A8 between Rosenheim and Salzburg and the associated legal opportunity to develop new traffic noise protection measures, this study investigated properties of sustainable noise abatement in a community next to the A8. A two-stage empirical survey was conducted integrating a citizen and an expert Delphi survey. The results show that the noise from the motorway heavily affects the quality of life in health, economic and ecological respects. Sustainable noise abatement should take into consideration ecological and social aspects like landscape integration and contribution to local development due to the unique location of the municipality. Enclosed motorway canopies are particularly beneficial to meet these criteria. The costs for sustainable noise abatement measures should be weighted as less important; however, financial costs are crucial for the federal government due to the requirements of the Federal Pollution Control Act. Hence, residents and experts assume that noise barriers as the cheaper noise abatement measures will be implemented. However, the results of the study and the latest developments in the expansion plans suggest that the implementation of enclosed motorway canopies, which go beyond the legal requirements, is feasible through extensive citizen participation and community-specific planning.

Promoting practical clinical management learning: the current situation about Information and Communications Technology capability development in student nurses.

Science.gov (United States)

Willmer, Marian

2005-11-01

This paper is about work-based learning in information management for student nurses. It seeks, through a literature review, to make a case for and promote Information and Communications Technology capability development in student nurses within their clinical environment. The profession of nursing, like many other jobs, is facing the increasing usage of information technology in day-to-day operations. Admission and discharges of patients have been held on computer databases since at least the 1980s. With the new Labour Government in 1997, increasing focus was placed on the effectiveness of the National Health Service and using computers as one way to assist in achieving greater effectiveness. Nurse education therefore needed to reflect this need and support trainee nurses to acquire skills in Information and Communications Technology. This paper is part of an ongoing professional doctorate inquiry into Information and Communications Technology capability development in student nurses. A literature search was conducted on teaching information and technology skills via Cumulative Index to Nursing and Allied Health Literature. Most of the available studies were neither based on the UK nor were they about student nurses. As there is a dearth of published work in this specific area, relevant, related and tangential literature was reviewed. It is argued that current practice and published work on Information and Communications Technology capability development by student nurses hardly exists. The literature confirmed that success in this area requires sound change management, an understanding of National Health Service culture, and effective people leadership skills. Nurse educators and managers need to pay more attention to understand how organizations work, particularly organizations where student nurses carry out their work. As the search revealed a significant gap in the literature in this area, a practical conceptual framework to fully analyse, develop and

2005-01-01

This article analyses the abatement costs of three post-Kyoto regimes for differentiating commitments compatible with stabilising atmospheric greenhouse gases concentrations at 550 ppmv CO 2 equivalent in 2100. The three regimes explored are: (1) the Multi-Stage approach assumes a gradual increase in the number of Parties involved who are adopting either emission intensity or reductions targets; (2) the Brazilian Proposal approach, i.e. the allocation or reductions based on countries' contribution to temperature increase; (3) Contraction and Convergence, with full participation in convergence of per capita emission allowances. In 2050, the global costs increase up to about 1% of the world GDP, ranging from 0.5% to 1.5%, depending on baseline scenario and marginal abatement costs. Four groups of regions can be identified on the basis of similar costs (expressed as the percentage of GDP). These are: (1) OECD regions with average costs; (2) FSU, the Middle East and Latin America with high costs; (3) South-East Asia and East Asia (incl. China) with low costs; and (4) South Asia (incl. India) and Africa with net gains from emissions trading for most regimes. The Brazilian Proposal approach gives the highest costs for groups 1 and 2. The distribution of costs for the Contraction and Convergence approach highly depends on the convergence year. The Multi-Stage approach and Contraction and Convergence (convergence year 2050) seem to result in relatively the most even distribution of costs amongst all Parties

Full Text Available The technology of artificial intelligence is actively being mastered in the world but there is not much talk about the capabilities of artificial intelligence in construction industry and this issue requires additional elaboration. As a rule, the decision to invest in a particular construction project is made on the basis of an assessment of the organizational and technological reliability of the construction process. Artificial intelligence can be a convenient quality tool for identifying, analyzing and subsequent control of the “pure” risks of the construction project, which not only will significantly reduce the financial and time expenditures for the investor’s decision-making process but also improve the organizational-technological reliability of the construction process as a whole. Subject: the algorithm of creation of artificial intelligence in the field of identification and analysis of potential risk events is presented, which will facilitate the creation of an independent analytical system for different stages of construction production: from the sketch to the working documentation and conduction of works directly on the construction site. Research objectives: the study of the possibility, methods and planning of the algorithm of works for creation of artificial intelligence technology in order to improve the organizational-technological reliability of the construction process. Materials and methods: the developments in the field of improving the organizational and technological reliability of construction were studied through the analysis and control of potential “pure” risks of the construction project, and the work was also carried out to integrate the technology of artificial intelligence into the area being studied. Results: An algorithm for creating artificial intelligence in the field of identification of potential “pure” risks of construction projects was presented. Conclusions: the obtained results are useful

Coastal aquatic ecosystems are increasingly affected by diffuse source nutrient water pollution from agricultural activities in coastal catchments, even though these ecosystems are important from a social, environmental and economic perspective. To warrant sustainable economic development of coastal regions, we need to balance marginal costs from coastal catchment water pollution abatement and associated marginal benefits from coastal resource appreciation. Diffuse-source water pollution abatement costs across agricultural sectors are not easily determined given the spatial heterogeneity in biophysical and agro-ecological conditions as well as the available range of best agricultural practices (BAPs) for water quality improvement. We demonstrate how the Soil and Water Assessment Tool (SWAT) can be used to estimate diffuse-source water pollution abatement cost functions across agricultural land use categories based on a stepwise adoption of identified BAPs for water quality improvement and corresponding SWAT-based estimates for agricultural production, agricultural incomes, and water pollution deliveries. Results for the case of dissolved inorganic nitrogen (DIN) surface water pollution by the key agricultural land use categories ("annual crops," "vineyards," and "mixed annual crops & vineyards") in the Vouga catchment in central Portugal show that no win-win agricultural practices are available within the assessed BAPs for DIN water quality improvement. Estimated abatement costs increase quadratically in the rate of water pollution abatement, with largest abatement costs for the "mixed annual crops & vineyards" land use category (between 41,900 and 51,900 € tDIN yr) and fairly similar abatement costs across the "vineyards" and "annual crops" land use categories (between 7300 and 15,200 € tDIN yr).

1994-01-01

Within the frame of UNEP's project on the Methodologies of Determining the Costs of Abatement of GHG emissions, a case study on Egypt was undertaken by the Technical Research Centre of Finland (VTT) in cooperation with the Egyptian Environment Affairs Authority (EEAA), together with an expert team from different Egyptian organizations. Both bottom-up and top-down approaches were used. Several measures/technologies, including energy conservation, fuel switching, use of renewable energy and material replacement, were considered to decrease CO 2 emissions. It was found that most of the measures were cost-effective, as a considerable potential for energy conservation exists in Egypt. The impact of energy conservation measures on the economy of the country was found to be positive using a macroeconomic model. (author)

A simple equilibrium business-cycle model for an economy with both clean- and dirty-producing plants is developed. The authors derive that the optimal timing of cleaning the production process is during a slowdown of the economy. Due to external effects and market failures the timing of pollution abatement investments is not expected to be optimal in the real world. We test the optimality of the timing of those investments with data for Germany, the Netherlands and the U.S.A. It appears that for more than 25 percent of the sectors pollution abatement investments show counter-cyclical behaviour, while in only one sector these investments are pro-cyclical. 1 tab., 3 appendices, 10 refs.

Iyer, Gokul C.; Clarke, Leon E.; Edmonds, James A.; Hultman, Nathan E.

2016-01-01

National-level policies to promote deployment of low-carbon technologies have been suggested and used as a means to reduce greenhouse gas emissions in the context of international climate change mitigation. The long-term benefits of such policies in the context of international climate change mitigation depend on their effects on near-term emissions abatement and resultant long-term technological change that will reduce abatement costs of achieving global mitigation goals. There is also an argument that these policies might foster early-mover advantages in international low-carbon technology markets. We first review the factors that could influence such benefits and use a global integrated assessment model to present an illustrative example to understand the potential magnitude of these benefits. We find that reductions in long-term abatement costs might not provide sufficient incentives to justify policies to promote the deployment of low-carbon technologies, in particular, the emerging, higher-risk, and currently expensive alternatives. We also find that early-mover advantages can potentially provide substantial benefits, but only if these advantages are both strong and persistent. Our results suggest a role for international cooperation in low-carbon technology deployment to address the existence of free-riding opportunities in the context of global climate change mitigation. - Highlights: • Study long-term benefits of low-carbon deployment in climate mitigation context. • Focus on reduced long-term abatement costs and early-mover advantage benefits . • Benefits depend on interactions among country, sector and technology factors. • Reduced long-term costs may not sufficiently incentivize expensive investments. • Early-mover advantages may incentivize such investments if strong and persistent.

Energy-saving and emission-abatement potential of Chinese coal-fired power enterprise: A non-parametric analysis

Wei, Chu; Löschel, Andreas; Liu, Bing

2015-01-01

In the context of soaring demand for electricity, mitigating and controlling greenhouse gas emissions is a great challenge for China's power sector. Increasing attention has been placed on the evaluation of energy efficiency and CO 2 abatement potential in the power sector. However, studies at the micro-level are relatively rare due to serious data limitations. This study uses the 2004 and 2008 Census data of Zhejiang province to construct a non-parametric frontier in order to assess the abatement space of energy and associated CO 2 emission from China's coal-fired power enterprises. A Weighted Russell Directional Distance Function (WRDDF) is applied to construct an energy-saving potential index and a CO 2 emission-abatement potential index. Both indicators depict the inefficiency level in terms of energy utilization and CO 2 emissions of electric power plants. Our results show a substantial variation of energy-saving potential and CO 2 abatement potential among enterprises. We find that large power enterprises are less efficient in 2004, but become more efficient than smaller enterprises in 2008. State-owned enterprises (SOE) are not significantly different in 2008 from 2004, but perform better than their non-SOE counterparts in 2008. This change in performance for large enterprises and SOE might be driven by the “top-1000 Enterprise Energy Conservation Action” that was implemented in 2006. - Highlights: • Energy-saving potential and CO 2 abatement-potential for Chinese power enterprise are evaluated. • The potential to curb energy and emission shows great variation and dynamic changes. • Large enterprise is less efficient than small enterprise in 2004, but more efficient in 2008. • The state-owned enterprise performs better than non-state-owned enterprise in 2008

For Chinese industry, the costs of different energy consumption abatement scenarios are evaluated by the method of directional distance function. These scenarios are based on the combinations of regulation strategies and allocation alternatives—the former are sectors and provinces, and the latter include the five principles of average, intensity share, absolute share, discriminatory absolute and discriminatory intensity. For all the scenarios, the quantitative impacts in terms of output potential loss are calculated and compared. Due to less output potential loss for all the allocation alternatives, the sector regulation strategy is shown to be more effective than the province regulation strategy. It is also demonstrated that, among all the scenarios considered, the sector regulation based on the intensity share principle and the province regulation based on the absolute share principle are the two optimal. The performances of energy abatement allocation of the 11th and 12th Five Year Plans of China are assessed against the simulated scenarios. - Highlights: ► The costs of different energy consumption abatement scenarios are evaluated for Chinese industry. ► The impacts on all entities under all allocation alternatives are calculated and compared. ► The optimal scenarios for the different strategies are identified. ► The performances of the 11th and 12th Five Year Plans are assessed.

Future needs for ship emission abatement and technical measures

Directory of Open Access Journals (Sweden)

Teresa ANTES

2013-01-01

Full Text Available The International Maritime Organization (IMO has revised air pollution regulations in MARPOL Annex VI. In 2012 Emission Control Areas (ECA will limit fuel sulphur content to 1% and from 2015 to 0.1%. NOx emissions based on ships engine speed are also reduced for new vessels (2012 & 2016. Facing this legislation, ship owners have the alternative either to operate ships with costly low-sulphur fuels, or to keep using HFO but together with a gas cleaning equipment at the ship stack in order to reduce the rejected amount of SO2 gas in the atmosphere. To achieve this requirement, research and development organizations came out with proposing a solution that uses a device for cleaning exhaust gas of marine diesel engines. The paper presents a short communication about the DEECON project, which aim is to create a novel on-board after-treatment unit more advanced than any currently available. Each sub-unit of the system will be optimized to remove a specific primary pollutant. In particular, the technology within the DEECON system is based on novel or improved abatement techniques for reducing SOx, NOx, Particulate Matter (PM, CO and Volatile Organic Compounds (VOC. Some of these technologies are completely new for the maritime sector and they will represent a breakthrough in the reduction of the atmospheric emissions of ships, moving forward the performance of exhaust gas cleaning systems and fostering and anticipating the adoption of future and tighter regulatory requirements. In addition, an after-treatment strategy enables the possible adoption of alternative fuels, which often have their own emissions characteristics.

Water Resources Research Program. Abatement of malodors at diked, dredged-material disposal sites. Final report

Energy Technology Data Exchange (ETDEWEB)

Harrison, W.; Dravnieks, A.; Zussman, R.; Goltz, R.

1976-06-01

Samples of malodorous air and dredged material were collected at diked disposal sites at the following locations: Buffalo, NY; Milwaukee, WI; Mobile, AL; York Harbor, ME; Houston, TX; Detroit, MI; and Anacortes, WA; during the period July--October, 1975. Odorous compounds in the air samples were identified by gas chromatography/mass spectrometry, while the detection threshold, intensity, and character of the various odors were determined by experienced panelists using a dynamic, forced-choice-triangle olfactometer. Although significant problems with malodors were not observed beyond the disposal-area dikes during site visits, noteworthy odor episodes had occurred at some sites. An odor-abatement strategy is presented for handling the expected range of odor conditions at dredged-material disposal sites. Its aim is to reduce to an acceptable level the intensity of malodors in an affected community. The main steps in the strategy cover selection of the disposal site, site preparation, odor characterization of sediments to be dredged, malodor abatement during dredging and disposal operations, malodor abatement after filling of the disposal site, and the handling of malodor complaints.

The focus of the presentation was on greenhouse gas mitigation options for the energy sector for India. Results from the Asia Least-cost Greenhouse gas Abatement Strategies (ALGAS) project were presented. The presentation comprised of a review of the sources of greenhouse gases, the optimisation model, ie the Markal model, used for determining the least-cost options, discussion of the results from the baseline and the abatement scenarios. The second half of the presentation focussed on a multi-criteria assessment of the abatement options using the Analytical Hierarchical Process (AHP) model. The emissions of all greenhouse gases, for India, are estimated to be 986.3 Tg of carbon dioxide equivalent for 1990. The energy sector accounted for 58 percent of the total emissions and over 90 percent of the CO2 emissions. Net emissions form land use change and forestry were zero. (au)

Efficiency, equity or disagreement? The economics of international carbon abatement negotiations

International Nuclear Information System (INIS)

Mabey, N.; Smith, C.

1995-01-01

The current international effort to reduce greenhouse gas emissions, as embodied in the Framework Convention on Climate Change, is often criticized as inefficient by economists because it uses uniform targets instead of more theoretically efficient instruments such as international taxes. However, the effectiveness of any international treaty in producing environmental benefits is not wholly dependent on its economic efficiency but also on its political stability and the ability to accurately monitor and enforce its conditions. Stability depends on the magnitude and distribution of costs and benefits between countries which have heterogeneous economies, environmental damages, trading partners and abatement costs. The distribution of costs between countries will also depend on the type of policy instrument used to coordinate international abatement efforts. This paper analyses trade-offs that must be made when negotiating international agreements in order to balance the need for administrative convenience and economic efficiency with the realization that any agreement is better than no agreement

The number of undergraduate-level textbooks on environmental economics has increased in recent years, but the textbook treatment of optimal emissions (abatement) varies markedly from textbook to textbook. In particular, there is no consensus as to whether to model the economic “bad” (i.e. emissions) or the economic “good” (abatement). This inconsistency can lead to some needless confusion for students introduced to environmental economics for the first time, particularly those students outsid...

AC low-pressure plasmas generated by using annular-shaped electrodes for abatement of pollutants emitted during semiconductor manufacturing processes

International Nuclear Information System (INIS)

2011-01-01

A plasma abatement system operating at low pressures is set up with the aim of treating pollutants emitted by the semiconductor industry. The abatement device is characterized by using a tube-shaped reactor design and a bipolar alternating current, which allows an easy connection to pre-existing pipelines in the semiconductor industry and low installation cost, respectively. By using optical emission spectroscopy (OES) and Fourier transform infrared spectroscopy (FTIR), we analyzed the discharge characteristics and abatement efficiency with emphasis on the working pressure effect. In the case of CF 4 , the destruction and removal efficiency (DRE) is greatly reduced with increasing pressure. However, the pressure has a relatively small influence on the DRE for tetrakis(ethylmethylamino)zirconium (TEMAZ), which is significantly destroyed only with several hundred watts and without any liquefied byproducts. This difference is closely related to the spatial distribution of reactive species and to the chemical bond strengths of the pollutant's components. Finally, the applicability of the abatement device is discussed based on the experimental results.

Firms that are dynamic and prepared to implement environmental strategies have a potential competitive advantage over their industry counterparts. Therefore, it is important to understand, what capabilities are required to implement proactive environmental strategies. The paper discusses the attributes of innovative capability required by firms in order to adopt pollution prevention and cleaner technology strategies. Empirical results show that process and behavioral innovativeness are required by firms to implement a pollution prevention strategy. In addition to process and behavioral innovativeness, firms need a top management with high risk-taking ability as well as market, product, and strategic innovativeness to implement a cleaner technology strategy. The paper proposes some important managerial implications on the basis of the above research findings. Copyright © 2015 Elsevier Ltd. All rights reserved.

Essays on the economics of energy markets. Security of supply and greenhouse gas abatement

Dieckhoener, Caroline

2013-01-01

In summary, the presented thesis analyzes two distinct economic subjects: security of supply in natural gas markets and greenhouse gas abatement potentials in the residential heating market. These subjects considered both reflect key points in the triangle of energy policy and are both associated with transnational market failures within energy markets. The security of supply analyses in an intermeshed network are approached from a rather normative, top-down perspective of a social planner. On the contrary, the analyses of greenhouse gases emitted by households are positive analyses of consumer choices. The normative analyses of security of supply in natural gas markets and the positive analyses on greenhouse gas abatement in the residential heating market are organized in two parts of the thesis. 1. Normative analyses - Security of supply in natural gas markets: The two papers of the first part of the dissertation thesis are based on a normative approach with the European natural gas market and infrastructure model TIGER that allows for security of supply analyses. The general idea behind the modeling approach is based on the assumption of a social planner and finds an efficient utilization of the natural gas infrastructure. More precisely, the security of supply analyses conducted in the first part of the thesis refer to scenario simulations of disrupted supply routes in the European natural gas network. The effects of these security of supply scenarios on the usage of other infrastructure components, on marginal supply costs and disruptions to consumers are investigated. 2. Positive analyses of greenhouse gas abatement potentials - Econometric modeling of consumer choices and evaluation of public policies: The second part of the thesis includes two positive analyses which investigate household choices to derive greenhouse gas abatement potentials. In the residential heating market, the energy efficiency level exhibited and the type of energy carrier used are

Estimating asbestos abatement projects: Excellence or 'You said I missed what'?

International Nuclear Information System (INIS)

Frawley, R.F.

1992-01-01

Between 1900 and 1980, 30 million tons of asbestos were put in place. Because of the known health hazards and increasing federal, state, and local regulations, building owners are now facing the problem of asbestos abatement. There are 4 basic approaches to dealing with asbestos: (1) removal, (2) enclosure, (3) encapsulation, (4) deferred action in conjunction with a well defined operations and maintenance program. Once the full extent of the problem is determined, the decision can be made on which action or combination of actions to take and begin estimating the cost of the asbestos abatement project. There are no high-tech methods of asbestos removal. It is hot, wet, labor intensive work, the ways of removal are archaic. Removal means man power and man hours, labor is a big ticket item, and is an important factor in cost estimating. Become very familiar with the scope of the project and be sure to fully understand the depth of the asbestos problem. The products, supplies, tools, and in some cases, the machines are all disposable items. If one overlooks something or underestimates the time involved for removal, not only will one be way off on material, the labor costs will soar. Be very observant on walk throughs, notice everything. Be sure to get clear, accurate test results on material to be removed. Once all this is done, one can make a good take off with confidence. Finally, when in doubt always remember the 11th commandment of asbestos abatement cost-estimating 'If thou can't figure it out hor-ellipsis thou best figure it in.'

Nitrate formation during ozonation as a surrogate parameter for abatement of micropollutants and the N-nitrosodimethylamine (NDMA) formation potential.

Science.gov (United States)

Song, Yang; Breider, Florian; Ma, Jun; von Gunten, Urs

2017-10-01

In this study, nitrate formation from ammonium and/or dissolved organic nitrogen (DON) was investigated as a novel surrogate parameter to evaluate the abatement of micropollutants during ozonation of synthetic waters containing natural organic matter (NOM) isolates, a natural water and secondary wastewater effluents. Nitrate formation during ozonation was compared to the changes in UV absorbance at 254 nm (UVA 254 ) including the effect of pH. For low specific ozone doses UVA 254 was abated more efficiently than nitrate was formed. This is due to a relatively slow rate-limiting step for nitrate formation from the reaction between ozone and a proposed nitrogen-containing intermediate. This reaction cannot compete with the fast reactions between ozone and UV-absorbing moieties (e.g., activated aromatic compounds). To further test the kinetics of nitrate formation, two possible intermediates formed during ozonation of DON were tested. At pH 7, nitrate was formed during ozonation of acetone oxime and methyl nitroacetate with second-order rate constants of 256.7 ± 4.7 M -1  s -1 and 149.5 ± 5.8 M -1  s -1 , respectively. The abatement of the selected micropollutants (i.e., 17α-ethinylestradiol (EE2), carbamazepine (CBZ), bezafibrate (BZF), ibuprofen (IBU), and p-chlorobenzoic acid (pCBA)) was investigated for specific ozone doses ≤1.53 mgO 3 /mgDOC and its efficiency depended strongly on the reactivity of the selected compounds with ozone. The relative abatement of micropollutants (i.e., EE2 and CBZ) with high ozone reactivity showed linear relationships with nitrate formation. The abatement of micropollutants with intermediate-low ozone reactivity (BZF, IBU, and pCBA) followed one- and two-phase behaviors relative to nitrate formation during ozonation of water samples containing high and low concentrations of nitrate-forming DON, respectively. During ozonation of a wastewater sample, the N-nitrosodimethylamine formation potential (NDMA-FP) during

Foram estudadas respostas fisiológicas do tambaqui ao estresse durante o pré-abate, que foi dividido em quatro etapas: despesca, transporte, recuperação por 24 h e por 48 h. Ao final de cada etapa, os peixes foram amostrados para caracterização do estresse pré-abate por meio de análises dos parâmetros plasmáticos de glicose, lactato e amônia e, em seguida, os peixes foram abatidos por hipotermia ou por asfixia com gás carbônico para o estudo do rigor mortis. Verificou-se que o estado fisiológico de estresse dos peixes foi mais agudo logo após o transporte, implicando numa entrada em rigor mortis mais rápida: 60 minutos para tambaquis abatidos por hipotermia e 120 minutos para tambaquis abatidos por asfixia com gás carbônico. Nos viveiros, os peixes abatidos logo após a despesca apresentaram estado de estresse intermediário, sem diferença no tempo de entrada em rigor mortis em relação ao método de abate (135 minutos. Os peixes que passaram por recuperação ao estresse causado pelo transporte em condições simuladas de indústria apresentaram entrada em rigor mortis mais tardia: 225 minutos (com 24 h de recuperação e 255 minutos (com 48 h de recuperação, igualmente sem diferença em relação aos métodos de abate testados. A resolução do rigor mortis foi mais rápida nos peixes abatidos após o transporte, que foi de 12 dias. Nos peixes abatidos logo após a despesca, a resolução ocorreu com 16 dias e, nos peixes abatidos após recuperação, com 20 dias para 24 h de recuperação ao estresse pré-abate e 24 dias para 48 h de recuperação, sem influência do método de abate na resolução do rigor mortis. Assim, é desejável que o abate do tambaqui destinado à indústria seja feito após período de recuperação ao estresse, com vistas a aumentar sua

Target groups as well as the government are under the spell of economic instruments as part of environmental policy. Under this heading fall (regulatory) taxes and tradeable emission permits (VER). Of the two, VER, particularly, receive a lot of attention. From the target groups, because the flexibility of VER means working cost-effectively, which could lead to cost savings. From the government, because it can have more faith in the viability of emission ceilings, and has less need to pass detailed legislation. The latter conforms nicely to the philosophy `government at arm`s length`. The Ministry of Environment has had a study made on the feasibility of VER in the context of the acidification abatement policy in the Netherlands. The development and implementation of policy concerning acidification abatement is at an advanced stage, with deposition targets already set for 2000 and 2010 (2400 and 1400 acid equivalents/ha/year, respectively, averaged for afforested areas). From these, also emission reduction targets per target group are deduced, which can be used in a VER system. The main starting point of the study was to gain more insight into the practical aspects of VER. One important question is what form a VER system for the Netherlands should have to take. Also, an investigation was made into the activities which are necessary to introduce a VER system as well as the time, manpower and money these activities entail

Conduction-driven cooling of LED-based automotive LED lighting systems for abating local hot spots

Science.gov (United States)

Saati, Ferina; Arik, Mehmet

2018-02-01

Light-emitting diode (LED)-based automotive lighting systems pose unique challenges, such as dual-side packaging (front side for LEDs and back side for driver electronics circuit), size, harsh ambient, and cooling. Packaging for automotive lighting applications combining the advanced printed circuit board (PCB) technology with a multifunctional LED-based board is investigated with a focus on the effect of thermal conduction-based cooling for hot spot abatement. A baseline study with a flame retardant 4 technology, commonly known as FR4 PCB, is first compared with a metal-core PCB technology, both experimentally and computationally. The double-sided advanced PCB that houses both electronics and LEDs is then investigated computationally and experimentally compared with the baseline FR4 PCB. Computational models are first developed with a commercial computational fluid dynamics software and are followed by an advanced PCB technology based on embedded heat pipes, which is computationally and experimentally studied. Then, attention is turned to studying different heat pipe orientations and heat pipe placements on the board. Results show that conventional FR4-based light engines experience local hot spots (ΔT>50°C) while advanced PCB technology based on heat pipes and thermal spreaders eliminates these local hot spots (ΔT<10°C), leading to a higher lumen extraction with improved reliability. Finally, possible design options are presented with embedded heat pipe structures that further improve the PCB performance.

Greenhouse Gas Abatement with Distributed Generation in California's Commercial Buildings

2009-01-01

Lawrence Berkeley National Laboratory (LBL) is working with the California Energy Commission (CEC) to determine the role of distributed generation (DG) in greenhouse gas reductions. The impact of DG on large industrial sites is well known, and mostly, the potentials are already harvested. In contrast, little is known about the impact of DG on commercial buildings with peak electric loads ranging from 100 kW to 5 MW. We examine how DG with combined heat and power (CHP) may be implemented within the context of a cost minimizing microgrid that is able to adopt and operate various smart energy technologies, such as thermal and photovoltaic (PV) on-site generation, heat exchangers, solar thermal collectors, absorption chillers, and storage systems. We use a mixed-integer linear program (MILP) that has the minimization of a site's annual energy costs as objective. Using 138 representative commercial sites in California (CA) with existing tariff rates and technology data, we find the greenhouse gas reduction potential for California's commercial sector. This paper shows results from the ongoing research project and finished work from a two year U.S. Department of Energy research project. To show the impact of the different technologies on CO2 emissions, several sensitivity runs for different climate zones within CA with different technology performance expectations for 2020 were performed. The considered sites can contribute between 1 Mt/a and 1.8 Mt/a to the California Air Resources Board (CARB) goal of 6.7Mt/a CO2 abatement potential in 2020. Also, with lower PV and storage costs as well as consideration of a CO2 pricing scheme, our results indicate that PV and electric storage adoption can compete rather than supplement each other when the tariff structure and costs of electricity supply have been taken into consideration. To satisfy the site's objective of minimizing energy costs, the batteries will be charged also by CHP systems during off-peak and mid-peak hours and

The economics of greenhouse gas mitigation: Insights from illustrative global abatement scenarios modelling

International Nuclear Information System (INIS)

Gurney, Andrew; Ahammad, Helal; Ford, Melanie

2009-01-01

In this paper the Global Trade and Environment Model (GTEM) and MAGICC are used to simulate a number of global emission mitigation scenarios devised by the EMF 22 Transition Scenarios group in which radiative forcing goals and the architecture of developing economies' participation in hypothetical mitigation actions are varied. This paper presents a reference case of the world economy to 2100 and analyses some key regional and global results for the various global mitigation scenarios, including emission prices, emission levels, primary energy consumption and economic growth. Modelling results suggest that a transition to a low-carbon world would require a significant decarbonisation of electricity generation without necessarily cutting the electricity output in the long run. With the uptake of hybrids and non-fossil-fuel technologies, the transport sector could make an important contribution to global abatement of greenhouse gases. Furthermore, with substantial international mitigation efforts and uptake of low- and/or zero-emission technologies, the achievement of 3.7 W/m 2 and 4.5 W/m 2 radiative forcing targets by the end of the century could occur at emission prices of up to $550/t CO 2 -e. However, achieving the 2.6 W/m 2 (overshoot) radiative forcing target would require considerably higher emission prices and an immediate global mitigation action.

Abatement of VOCs with Alternate Adsorption and Plasma-Assisted Regeneration: A Review

Directory of Open Access Journals (Sweden)

Sharmin Sultana

2015-04-01

Full Text Available Energy consumption is an important concern for the removal of volatile organic compounds (VOCs from waste air with non-thermal plasma (NTP. Although the combination of NTP with heterogeneous catalysis has shown to reduce the formation of unwanted by-products and improve the energy efficiency of the process, further optimization of these hybrid systems is still necessary to evolve to a competitive air purification technology. A newly developed innovative technique, i.e., the cyclic operation of VOC adsorption and NTP-assisted regeneration has attracted growing interest of researchers due to the optimized energy consumption and cost-effectiveness. This paper reviews this new technique for the abatement of VOCs as well as for regeneration of adsorbents. In the first part, a comparison of the energy consumption between sequential and continuous treatment is given. Next, studies dealing with adsorption followed by NTP oxidation are reviewed. Particular attention is paid to the adsorption mechanisms and the regeneration of catalysts with in-plasma and post-plasma processes. Finally, the influence of critical process parameters on the adsorption and regeneration steps is summarized.

High ambient ozone (O3) concentrations are a widespread and persistent problem globally. Although studies have documented the role of forests in removing O3 and one of its precursors, nitrogen dioxide (NO2), the cost effectiveness of using peri-urban reforestation for O3 abatement purposes has not been examined. We develop a methodology that uses available air quality and meteorological data and simplified forest structure growth-mortality and dry deposition models to assess the performance of reforestation for O3 precursor abatement. We apply this methodology to identify the cost-effective design for a hypothetical 405-ha, peri-urban reforestation project in the Houston–Galveston–Brazoria O3 nonattainment area in Texas. The project would remove an estimated 310 tons of (t) O3 and 58 t NO2 total over 30 y. Given its location in a nitrogen oxide (NOx)-limited area, and using the range of Houston area O3 production efficiencies to convert forest O3 removal to its NOx equivalent, this is equivalent to 127–209 t of the regulated NOx. The cost of reforestation per ton of NOx abated compares favorably to that of additional conventional controls if no land costs are incurred, especially if carbon offsets are generated. Purchasing agricultural lands for reforestation removes this cost advantage, but this problem could be overcome through cost-share opportunities that exist due to the public and conservation benefits of reforestation. Our findings suggest that peri-urban reforestation should be considered in O3 control efforts in Houston, other US nonattainment areas, and areas with O3 pollution problems in other countries, wherever O3 formation is predominantly NOx limited.

Cogeneration plant noise: Environmental impacts and abatement

International Nuclear Information System (INIS)

De Renzio, M.; Ciocca, B.

1991-01-01

In Italy, ever increasing attention to environmental problems has led to legislation requiring cogeneration plant owners to perform environmental impact assessments in order to determine plant conformity with pollution laws. This paper, based on an in-depth analysis of physics fundamentals relevant to the nature and effects of noise, examines the principal sources of noise in industrial cogeneration plants and the intensity and range of the effects of this noise on the local environment. A review is then made of the different methods of noise pollution abatement (e.g., heat and corrosion resistant silencers for gas turbines, varying types and thicknesses of acoustic insulation placed in specific locations) that can be effectively applied to cogeneration plant equipment and housing

Electrochemical processes in macro and microfluidic cells for the abatement of chloroacetic acid from water

International Nuclear Information System (INIS)

Scialdone, O.; Corrado, E.; Galia, A.; Sirés, I.

2014-01-01

Highlights: • The electrochemical abatement of chloroacetic acid in water was studied. • The performance of both macro and microfluidic reactors was examined. • Cathodic reduction and anodic oxidation was studied in detail. • Mediated oxidation by electro-Fenton and active chlorine was carried out. • Anodic oxidation at BDD gave better performances. • Microfluidic reactors gave better performances compared to conventional cells. - Abstract: The remediation of solutions contaminated with monochloroacetic acid (CAA), which is one of the most resistant haloacetic acids (HAAs) to chemical degradation, dramatically depends on the adopted electrochemical approach: (i) CAA is only poorly oxidized either by homogeneous hydroxyl radical in electro-Fenton (EF), electrogenerated active chlorine or electro-oxidation on Pt anode; (ii) it is moderately abated by direct reduction on silver or compact graphite cathodes (from 30% in macro cells to 60% in the microfluidic devices); (iii) it is quantitatively removed by direct electro-oxidation on a boron-doped diamond (BDD) anode. The use of a microreactor enables operation in the absence of supporting electrolyte and drastically enhances the performance of the cathodic process. Simultaneously performing direct oxidation on BDD and reduction on graphite in a microfluidic cell yields the fastest CAA removal with 100% abatement at low current densities (∼5 mA cm −2 )

Bataille, Ch.; Birraux, C.

The abatement of CO 2 emissions is a huge technical and economical challenge. Fossil fuels, which represent 88% of the world primary energy consumption, are the main source of the 25 billions of CO 2 released each year in the atmosphere. The mastery of CO 2 emissions cannot come from a single technology but must result from the simultaneous implementation of several means, like the development of carbon-free energies and the mastery of fossil fuel emissions. The opportunities of progress are numerous and compatible with the economic development. This document presents, first, the different greenhouse gases, the CO 2 emissions per country and the main sources of CO 2 emissions (power and heat generation, transports). Then it presents different ways of abatement of CO 2 emissions: clean coal technologies, gas combined cycles, CO 2 sequestration, reduction of fuel consumption in transports, development of carbon-free energies: wind power, solar photovoltaic for decentralized power generation, nuclear energy for a competitive power generation and for CO 2 abatement, biofuels of 2. generation and fuel cells. The conclusion stresses on the investments needed for the renewal and increase of energy capacities, and on the necessary visibility and moderation of emission abatement mechanisms (carbon trading and CO 2 prices).

A qualitative and quantitative approach forms the base of this analysis of the results of "Vida Digna," a project aimed at abating stigma and discrimination in the HIV transmission field with actions taken by civil society organizations from 2005 to 2009 in the Mexican region of El Bajío. The results were analyzed in 2009 and 2010. The organizations involved were made up of key populations, defined as groups vulnerable to infection but also capable of resisting and controlling the transmission of HIV and the stigma and discrimination that are important barriers in the seeking of care and the achievement of effective HIV control. We describe and analyze the actions taken and the strengthening of the participating organizations. The visibility of new social actors such as transgender women and injecting drug users, as well as informative activities directed at journalists, the police and the military to prevent the criminalization and persecution of these groups, are highlighted.

Ex-ante evaluation of EU ETS during 2013–2030: EU-internal abatement

Hu, Jing; Crijns-Graus, Wina; Lam, Long; Gilbert, Alyssa

2015-01-01

This study investigates CO 2 emission reduction within the EU resulting from the Emissions Trading Scheme (ETS) up to 2030. This is performed by constructing a baseline scenario without the ETS and assessing the impacts of the ETS, as currently designed. The results indicate that the ETS will start to impact emissions primarily after 2025 due to the prevalence of a sizable allowance surplus. The impact of approved (i.e. back-loading and 2.2% linear reduction factor (LRF)) and proposed (i.e. market stability reserve (MSR)) policy interventions and the inclusion of aviation, could accelerate the exhaustion of surplus and increase emission reductions during the investigated period. However, these measures would be insufficient to restore the scarcity of allowances and the corresponding carbon price before the start of ETS Phase IV, and the effectiveness of EU-internal abatement cannot be guaranteed until 2023. The effectiveness could be further reduced in the case of the economic shocks or the exclusion of international aviation. To restore the scarcity of allowances, other reform options are necessary. This paper extends the reasoning for the early removal of the back-loaded 900 Mtonne allowances by 2020 and broadening the scope of ETS to other sectors with potential high demand for allowances. - Highlights: • Quantification of CO 2 emission abatement in the EU resulting from the ETS up to 2030. • The impact of policy interventions and the inclusion of aviation is quantified. • The effectiveness of EU ETS in EU-internal abatement is limited until 2023

Ammonia emissions from livestock industries in Canada: Feasibility of abatement strategies

International Nuclear Information System (INIS)

Carew, Richard

2010-01-01

An updated national ammonia (NH 3 ) emissions inventory was employed to study the relationship between NH 3 emissions and livestock industries in Canada. Emissions from animal agriculture accounted for 322 kilotonnes (kt) or 64% of Canadian NH 3 emissions in 2002. Cattle and swine accounted for the bulk of livestock emissions. The provinces of Alberta, Ontario, Quebec, and Saskatchewan accounted for 28.1%, 22.0%, 18.7%, and 13.1% of total livestock emissions, respectively. Emissions from Ontario and Quebec were attributed to the intensive production of dairy, hogs and poultry. Dairy cattle emissions per hectolitre of milk were higher in Ontario and Quebec than in other provinces, while swine emissions per livestock unit were higher than either beef or dairy cattle. A review of the abatement literature indicated diet manipulation to improve N efficiency and land spreading methods are very effective techniques to lower NH 3 emissions. Future research is required to evaluate the feasibility of biofilters and feces/urine separation methods. - Livestock NH 3 emissions are higher in areas characterized by intensive livestock production with diet manipulation and land spreading offering the greatest potential for NH 3 abatement options.

The timing of biological carbon sequestration and carbon abatement in the energy sector under optimal strategies against climate risks

International Nuclear Information System (INIS)

Gitz, V.; Hourcade, J.Ch.; Ciais, Ph.

2005-10-01

This paper addresses the timing of the use of biological carbon sequestration and its capacity to alleviate the carbon constraint on the energy sector. We constructed a stochastic optimal control model balancing the costs of fossil emission abatement, the opportunity costs of lands allocated to afforestation, and the costs of uncertain climate damages. We show that a minor part of the sequestration potential should start immediately as a 'brake', slowing down both the rate of growth of concentrations and the rate of abatement in the energy sector. thus increasing the option value of the emission trajectories. But, most of the potential is put in reserve to be used as a 'safety valve' after the resolution of uncertainty, if a higher and faster decarbonization is required: sequestration cuts off the peaks of costs of fossil abatement and postpones the pivoting of the energy system by up to two decades.

Gupta, S.

1995-01-01

Global warming and associated climate change are the likely results of an enhanced greenhouse effect due to excessive emission of greenhouse gases. Carbon dioxide (CO 2 ) is the largest contributor to the greenhouse effect. The costs of stabilising or reducing CO 2 emissions are estimated by two types of models. Macro models based on aggregate macroeconomic relationships, study the macroeconomic impacts of and responses to different policies. These overestimate costs as technological responses are not adequately modelled. Micro models contain the necessary technical information to assess the abatement potential, but exclude indirect costs. In this study, a methodology for integrating the two approaches for developing countries is proposed and illustrated for India. The problems associated with modelling developing economies are recognized in the integrated model proposed. (Author)

Most economic activities pollute. Environmental regulations should serve the public good by providing incentives to reduce pollution caused by economic activity. Economic incentives include pollution taxes, subsidies for pollution abatement, and tradeable permits or allowances to pollute. Because of the political unacceptability of taxes and permits, much regulation imposes command and control measures and provides less incentive to minimize pollution. Efficient incentives would encourage pollution abatement up to the point where the cost of abatement equals the social and private benefit from the improvements in the environment. While these costs and benefits are difficult to measure, many analysts contend that the way environmental laws have been formulated and implemented in the US leads to very inefficient pollution control. This inefficiency can contribute to a decline in economic competitiveness in the long run, although economic studies do not support the ``pollution haven`` hypothesis. Better analysis (foresight) of the cost of transboundary pollution, significant in the Great Lakes region and along the US- Mexico border, as well as in rivers that flow between countries, is needed to formulate more effective policies and avoid sorry hindsight. Also, application of communal experience, technologies, and methods applied to shared problems can avoid costly duplication of searches for the optimal pollution abatement measures. 14 refs.

Research on the application of active sound barriers for the transformer noise abatement

Full Text Available Sound barriers are a type of measure most commonly used in the noise abatement of transformers. In the noise abatement project of substations, the design of sound barriers is restrained by the portal frames which are used to hold up outgoing lines from the main transformers, which impacts the noise reduction effect. If active sound barriers are utilized in these places, the noise diffraction of sound barriers can be effectively reduced. At a 110kV Substation, an experiment using a 15-channel active sound barrier has been carried out. The result of the experiment shows that the mean noise reduction value (MNRV of the noise measuring points at the substation boundary are 1.5 dB (A. The effect of the active noise control system is impacted by the layout of the active noise control system, the acoustic environment on site and the spectral characteristic of the target area.

Full Text Available Gastro-esophageal reflux disease (GERD is partly caused by genetic factors. The underlying susceptibility genes are currently unknown, with the exception of COL3A1. We used three independent GERD patient cohorts to identify GERD susceptibility genes. Thirty-six families, demonstrating dominant transmission of GERD were subjected to whole genome microsatellite genotyping and linkage analysis. Five linked regions were identified. Two families shared a linked region (LOD 3.9 and 2.0 on chromosome 16. We used two additional independent GERD patient cohorts, one consisting of 219 trios (affected child with parents and the other an adult GERD case control cohort consisting of 256 cases and 485 controls, to validate individual genes in the linked region through association analysis. Sixty six single nucleotide polymorphism (SNP markers distributed over the nine genes present in the linked region were genotyped in the independent GERD trio cohort. Transmission disequilibrium test analysis followed by multiple testing adjustments revealed a significant genetic association for one SNP located in an intron of the gene 4-aminobutyrate aminotransferase (ABAT (P(adj = 0.027. This association did not replicate in the adult case-control cohort, possibly due to the differences in ethnicity between the cohorts. Finally, using the selective ABAT inhibitor vigabatrin (γ-vinyl GABA in a dog study, we were able to show a reduction of transient lower esophageal sphincter relaxations (TLESRs by 57.3 ± 11.4 % (p = 0.007 and the reflux events from 3.1 ± 0.4 to 0.8 ± 0.4 (p = 0.007. Our results demonstrate the direct involvement of ABAT in pathways affecting lower esophageal sphincter (LES control and identifies ABAT as a genetic risk factor for GERD.

Sunday Adekunle Aduloju

2014-12-01

Full Text Available The potential of information technology (IT as an enabler of customer service process continues to generate interest, which is reflected in the large number of IT-related studies. In spite of the significant progress made in this area, research findings have been mixed and inconsistent. Also, the underlying mechanisms by which IT can affect customer service process remain underexamined. The aim of this study was to find out whether IT investments and IT managerial capabilities can account for variations in customer service performance among insurance companies in Nigeria. Using survey research design, the three formulated hypotheses were tested with data gathered from 402 staff at the managerial level drawn from the selected insurance companies in Nigeria, which have been among the largest investors in IT, and where customer service is widely perceived as strategically important. Responses were analyzed using linear regression. A major finding of this study is that IT is a necessary, but not sufficient, condition for sustainable competitive advantage in customer service. Results show that the interaction of IT investments and tacit, path-dependent, and firm-specific IT managerial capabilities significantly explains variations in customer service performance. Consequently, this study recommends that to realize IT-business value, investments in IT should be accompanied by building and developing IT managerial capabilities.

2011-05-15

The goal of the Development of High Temperature Capacitor Technology and Manufacturing Capability program was to mature a production-ready supply chain for reliable 250°C FPE (fluorinated polyester) film capacitors by 2011. These high-temperature film capacitors enable both the down hole drilling and aerospace industries by enabling a variety of benefits including: - Deeper oil exploration in higher temperature and pressure environments - Enabling power electronic and control equipment to operate in higher temperature environments - Enabling reduced cooling requirements of electronics - Increasing reliability and life of capacitors operating below rated temperature - Enabling capacitors to handle higher electrical losses without overheating. The key challenges to bringing the FPE film capacitors to market have been manufacturing challenges including: - FPE Film is difficult to handle and wind, resulting in poor yields - Voltage breakdown strength decreases when the film is wound into capacitors (~70% decrease) - Encapsulation technologies must be improved to enable higher perature operation - Manufacturing and test cycle time is very long As a direct result of this program most of the manufacturing challenges have been met. The FPE film production metalization and winding yield has increased to over 82% from 70%, and the voltage breakdown strength of the wound capacitors has increased 270% to 189 V/μm. The high temperature packaging concepts are showing significant progress including promising results for lead attachments and hermetic packages at 200°C and non-hermetic packages at 250°C. Manufacturing and test cycle time will decrease as the market for FPE capacitors develops.

National energy cost optimization and project implementation: Two different worlds?. Discussion paper in the framework of the UNEP Greenhouse Gas Abatement Costing Studies

International Nuclear Information System (INIS)

Van Harmelen, T.

1994-08-01

One of the main targets of the UNEP Greenhouse Gas Abatement Costing Study is combining the techno-economic and purely economic modelling approaches into one overall modelling methodology for greenhouse gas abatement costing studies. This type of models can be categorized as bottom-up models, since technology data on a very detailed level result in costs and emissions on a national level. In contrast with, but not necessarily in conflict with these models, macro-economists rely in general on macro-economic models which derive economic projections from aggregated national and sectorial economic data. These so called top-down models describe the complete national economy. Therefore the energy sector is modelled in a very aggregated way. Since the micro-economic and techno-economic approaches can be classified both as bottom-up approaches, it could be expected that mutual understanding exists. However, this is not true for all issues in this field. Techno-economical views and micro-economic views differ for instance on the implementation of options. This topic drew attention during the UNEP study, next to other items as techno-economic and macro-economic model assessments of the costs of CO 2 abatement. One of the most important implementation issues is the so-called negative cost (benefit) potential of energy saving options, which exists in the techno-economic view at this very moment, but which is not implemented yet. In the view of micro-economic analysis this potential does not exist, since options which are profitable would have been implemented according to presently adopted cost-benefit theory. Several aspects of this controversy have been discussed extensively elsewhere. In this paper the two visions are summarized and it is discussed whether it is fruitful to combine techno-economic and micro-economic approaches in an overall methodological framework. 1 tabs., 8 refs

New Cryogenic Optical Test Capability at Marshall Space Flight Center's Space Optics Manufacturing Technology Center

Kegley, Jeff; Burdine, Robert V. (Technical Monitor)

2002-01-01

A new cryogenic optical testing capability exists at Marshall Space Flight Center's Space Optics Manufacturing Technology Center (SOMTC). SOMTC has been performing optical wavefront testing at cryogenic temperatures since 1999 in the X-ray Cryogenic Test Facility's (XRCF's) large vacuum chamber. Recently the cryogenic optical testing capability has been extended to a smaller vacuum chamber. This smaller horizontal cylindrical vacuum chamber has been outfitted with a helium-cooled liner that can be connected to the facility's helium refrigeration system bringing the existing kilowatt of refrigeration capacity to bear on a 1 meter diameter x 2 meter long test envelope. Cryogenic environments to less than 20 Kelvin are now possible in only a few hours. SOMTC's existing instruments (the Instantaneous Phase-shifting Interferometer (IPI) from ADE Phase-Shift Technologies and the PhaseCam from 4D Vision Technologies) view the optic under test through a 150 mm clear aperture BK-7 window. Since activation and chamber characterization tests in September 2001, the new chamber has been used to perform a cryogenic (less than 30 Kelvin) optical test of a 22.5 cm diameter x 127 cm radius of curvature Si02 mirror, a cryogenic survival (less than 30 Kelvin) test of an adhesive, and a cryogenic cycle (less than 20 Kelvin) test of a ULE mirror. A vibration survey has also been performed on the test chamber. Chamber specifications and performance data, vibration environment data, and limited test results will be presented.

Separating environmental efficiency into production and abatement efficiency. A nonparametric model with application to U.S. power plants

Energy Technology Data Exchange (ETDEWEB)

Hampf, Benjamin

2011-08-15

In this paper we present a new approach to evaluate the environmental efficiency of decision making units. We propose a model that describes a two-stage process consisting of a production and an end-of-pipe abatement stage with the environmental efficiency being determined by the efficiency of both stages. Taking the dependencies between the two stages into account, we show how nonparametric methods can be used to measure environmental efficiency and to decompose it into production and abatement efficiency. For an empirical illustration we apply our model to an analysis of U.S. power plants.

The technologies are developed for efficiently, economically improving quality of automobile fuels by, e.g., abatement of environmental pollutants present in the oil products. For improvement of hydrodesulfurization rate of gas oil deep hydrodesulfurization process, the catalyst components high in isomerization ability of the hard-to-desulfurize compounds are investigated, and effectiveness of zeolite is confirmed. For production of low-sulfur gas oil by hydrodesulfurization and hydrocracking of heavy oil, the catalyst with small pores is preferable for desulfurization of gas oil as the co-product of the treatment of heavy oil in the presence of catalyst for heavy oil desulfurization. For hydrocracking, the catalysts are prepared, on a trial basis, for achieving the target gas oil sulfur content of 10ppm or less by optimizing the zeolite and matrix properties. For suitability of gas oil qualities, it is found that the hydrogenation step is the rate-determining step among the reaction routes involved in the hydrogenation of difficult-to-desulfurize compounds. The data of low-sulfur gas oil qualities in Europe are collected. (NEDO)

EMSP Final Report: Electrically Driven Technologies for Radioactive Aerosol Abatement

Energy Technology Data Exchange (ETDEWEB)

DePaoli, D.W.

2003-01-22

The purpose of this research project was to develop an improved understanding of how electrically driven processes, including electrocoalescence, acoustic agglomeration, and electric filtration, may be employed to efficiently treat problems caused by the formation of aerosols during DOE waste treatment operations. The production of aerosols during treatment and retrieval operations in radioactive waste tanks and during thermal treatment operations such as calcination presents a significant problem of cost, worker exposure, potential for release, and increased waste volume. There was anecdotal evidence in the literature that acoustic agglomeration and electrical coalescence could be used together to change the size distribution of aerosol particles in such a way as to promote easier filtration and less frequent maintenance of filtration systems. As such, those electrically driven technologies could potentially be used as remote technologies for improved treatment; however, existing theoretical models are not suitable for prediction and design. To investigate the physics of such systems, and also to prototype a system for such processes, a collaborative project was undertaken between Oak Ridge National Laboratory (ORNL) and the University of Texas at Austin (UT). ORNL was responsible for the larger-scale prototyping portion of the project, while UT was primarily responsible for the detailed physics in smaller scale unit reactors. It was found that both electrical coalescence and acoustic agglomeration do in fact increase the rate of aggregation of aerosols. Electrical coalescence requires significantly less input power than acoustic agglomeration, but it is much less effective in its ability to aggregate/coalesce aerosols. The larger-scale prototype showed qualitatively similar results as the unit reactor tests, but presented more difficulty in interpretation of the results because of the complex multi-physics coupling that necessarily occur in all larger

The abatement of CO{sub 2} emissions is a huge technical and economical challenge. Fossil fuels, which represent 88% of the world primary energy consumption, are the main source of the 25 billions of CO{sub 2} released each year in the atmosphere. The mastery of CO{sub 2} emissions cannot come from a single technology but must result from the simultaneous implementation of several means, like the development of carbon-free energies and the mastery of fossil fuel emissions. The opportunities of progress are numerous and compatible with the economic development. This document presents, first, the different greenhouse gases, the CO{sub 2} emissions per country and the main sources of CO{sub 2} emissions (power and heat generation, transports). Then it presents different ways of abatement of CO{sub 2} emissions: clean coal technologies, gas combined cycles, CO{sub 2} sequestration, reduction of fuel consumption in transports, development of carbon-free energies: wind power, solar photovoltaic for decentralized power generation, nuclear energy for a competitive power generation and for CO{sub 2} abatement, biofuels of 2. generation and fuel cells. The conclusion stresses on the investments needed for the renewal and increase of energy capacities, and on the necessary visibility and moderation of emission abatement mechanisms (carbon trading and CO{sub 2} prices).

The paper deals with the diffusion of GHG mitigation technologies in developing countries. We develop a model where an abatement technology is progressively adopted by firms and we use it to compare the Clean Development Mechanism (CDM) with a standard Cap and Trade scheme (C and T). In the presence of learning spillovers, we show that the CDM yields a higher social welfare than C and T if the first adopter receives CDM credits whereas the followers do not. This result lends support to the policy proposal of relaxing the CDM additionality constraint for projects which generate significant learning externalities. (authors)

Full Text Available Customer relationship management, as a process to manage customer relationship initiation, maintenance and termination to maximize the value of the relationship portfolio, is an evolving process. In recent years, the development of interactive technologies (social media have revolutionized the interaction between firms and their customers and between customers. The impact of technology on CRM is improving ways of collecting and processing customer information and transforming communication with customers. In the context of the development of social networks, the introduction of social media applications in customer relationship management activities bring important changes in this area. Thus, managers need to pay attention to the interaction management as an important process of CRM and enhance the customer relationship management capabilities. The study propose a conceptual research model of several antecedents of customer relationship managements capabilities and provide the linkage between this antecedents and CRM capabilities. First, following review of existing research literature related to customer relationship management, there are some conceptual clarification on customer relationship management. Second, are presented the working concepts: the adoption of interactive technologies, customer concept, customer empowerment, customer relationship orientation and customer-centric management system. Then, it is proposed the conceptual model and finally are presented conclusions, managerial implications, limitations and research directions. From a theoretical perspective, this paper highlights the importance of marketing actions at the individual customer level and reveal the impact of adoption by companies of interactive technologies so that organizations have the opportunity to engage in conversations with customers and respond in real time the requirements that they launched the online environment. Nowadays, customers feel empowered and play

Energy and GHG abatement cost curves

Alvarenga, Rafael [BHP Billiton Base Metals (Australia)

2010-07-01

Global warming due to various reasons but especially to emission of green house gases (GHGs) has become a cause for serious concern. This paper discusses the steps taken by BHP Billiton to reduce energy consumption and GHG emissions using cost curves. According to forecasts, global warming is expected to impact Chile badly and the rise in temperature could be between 1 and more than 5 degrees Celsius. Mining in Chile consumes a lot of energy, particularly electricity. Total energy and electricity consumption in 2007 was 13 and 36 % respectively. BHP base metals developed a set of abatement cost curves for energy and GHG in Chile and these are shown in figures. The methodology for the curves consisted of consultant visits to each mine operation. The study also includes mass energy balance and feasibility maps. The paper concludes that it is important to evaluate the potential for reducing emissions and energy and their associated costs.

Macro economic linkages and impacts. Technical and fiscal options in GHG abatement

International Nuclear Information System (INIS)

Backus, G.; Barker, T.

1995-01-01

This paper discusses some of the main macro economic linkages and feedbacks associated with policies for GHG abatement. The linkages in a global model are described when OECD carbon taxes or alternatively OECD/OPEC joint action raises world oil prices with a smaller OECD carbon tax. The results give a world perspective on the GHG abatement problem. The paper continues with a discussion of the linkages and feedbacks associated with three options: demand-side management (DSM), mainly to improve end-use energy efficiency, reductions in subsidies of fossil fuel production and use, and investment in renewable energy supplies, specifically in energy forestry and associated infrastructure. It concludes that DSM and investment in renewables are unlikely on their own to bring about reduction in GHG emissions, and that new supplies may even lead to increased emissions by driving down the price of energy. However, reductions in emissions may be compatible with increased efficiency and development, as well as with improvements in the quality of the local environment and in rural living, with the new supplies replacing fossil fuel supplies, provided that real fossil fuel prices are increased via removal of subsidies and if required carbon taxes.

Airborne exposure and soil levels associated with lead abatement of a steel tank.

Science.gov (United States)

Lange, John H

2002-02-01

This study reports on airborne exposure levels and soil concentrations of lead in regard to abatement of a steel structure (water tank). The tank was de-leaded by abrasive sand blasting. The ball of the tank had a lead surface level that exceeded the Environmental Protection Agency (EPA) definition of lead-based paint (LBP) (0.5% lead), but paint on stem and base was below this criterion. Personal and area airborne samples were collected during different activities of lead abatement of the tank. Summary results suggest during abrasive blasting of ball and stem/base personal exposure levels, as reported with arithmetic and geometric means, exceed the Occupational Safety and Health Administration (OSHA) permissible exposure limit (50 microg/m3). Highest personal exposure (occupational exposure) was associated with blasting of ball. Distribution of airborne and soil samples suggest non-normality and is best represented by a logarithmic form. Geometric standard deviations for air and soil lead support a non-normal distribution. Outlying values were found for personal and area air samples. Exposure levels associated with blasting stem/base section of tank support OSHA's policy requiring air monitoring of work at levels below the criterion established by EPA in identifying LBP. Area samples were statistically lower than personal samples associated with blasting ball and stem/base of tank. Exposure data suggest that workers performing abatement on steel structures have elevated lead exposure from surface lead. Respirator protection requirements are discussed. Soil lead concentration was suggested to decrease as distance increased from tank. Soil lead is suggested to be a result of deposition from LBP on tank surface. Minimal efforts were required to reduce average lead soil levels below EPA's upper acceptable criterion (1200 ppm Pb).

Capability assessment and challenges for quantum technology gravity sensors for near surface terrestrial geophysical surveying

Science.gov (United States)

Boddice, Daniel; Metje, Nicole; Tuckwell, George

2017-11-01

Geophysical surveying is widely used for the location of subsurface features. Current technology is limited in terms of its resolution (thus size of features it can detect) and penetration depth and a suitable technique is needed to bridge the gap between shallow near surface investigation using techniques such as EM conductivity mapping and GPR commonly used to map the upper 5 m below ground surface, and large features at greater depths detectable using conventional microgravity (> 5 m below ground surface). This will minimise the risks from unknown features buried in and conditions of the ground during civil engineering work. Quantum technology (QT) gravity sensors potentially offer a step-change in technology for locating features which lie outside of the currently detectable range in terms of size and depth, but that potential is currently unknown as field instruments have not been developed. To overcome this, a novel computer simulation was developed for a large range of different targets of interest. The simulation included realistic noise modelling of instrumental, environmental and location sources of noise which limit the accuracy of current microgravity measurements, in order to assess the potential capability of the new QT instruments in realistic situations and determine some of the likely limitations on their implementation. The results of the simulations for near surface features showed that the new technology is best employed in a gradiometer configuration as opposed to the traditional single sensor gravimeter used by current instruments due to the ability to suppress vibrational environmental noise effects due to common mode rejection between the sensors. A significant improvement in detection capability of 1.5-2 times was observed, putting targets such as mineshafts into the detectability zone which would be a major advantage for subsurface surveying. Thus this research, for the first time, has demonstrated clearly the benefits of QT gravity

Abatement cost of GHG emissions for wood-based electricity and ethanol at production and consumption levels.

Directory of Open Access Journals (Sweden)

Puneet Dwivedi

Full Text Available Woody feedstocks will play a critical role in meeting the demand for biomass-based energy products in the US. We developed an integrated model using comparable system boundaries and common set of assumptions to ascertain unit cost and greenhouse gas (GHG intensity of electricity and ethanol derived from slash pine (Pinus elliottii at the production and consumption levels by considering existing automobile technologies. We also calculated abatement cost of greenhouse gas (GHG emissions with respect to comparable energy products derived from fossil fuels. The production cost of electricity derived using wood chips was at least cheaper by 1 ¢ MJ-1 over electricity derived from wood pellets. The production cost of ethanol without any income from cogenerated electricity was costlier by about 0.7 ¢ MJ-1 than ethanol with income from cogenerated electricity. The production cost of electricity derived from wood chips was cheaper by at least 0.7 ¢ MJ-1 than the energy equivalent cost of ethanol produced in presence of cogenerated electricity. The cost of using ethanol as a fuel in a flex-fuel vehicle was at least higher by 6 ¢ km-1 than a comparable electric vehicle. The GHG intensity of per km distance traveled in a flex-fuel vehicle was greater or lower than an electric vehicle running on electricity derived from wood chips depending on presence and absence of GHG credits related with co-generated electricity. A carbon tax of at least $7 Mg CO2e-1 and $30 Mg CO2e-1 is needed to promote wood-based electricity and ethanol production in the US, respectively. The range of abatement cost of GHG emissions is significantly dependent on the harvest age and selected baseline especially for electricity generation.

China’s regional industrial energy efficiency and carbon emissions abatement costs

Graphical abstract: Major cities in eight economy-geography regions of China. - Highlights: • Industrial energy and emissions efficiency were evaluated for China’s major cities. • Shadow prices of CO 2 emissions were estimated for China’s major cities. • Efficiency increase potentials on energy utilization and CO 2 emissions are 19% and 17%. • N-shaped EKC exists between levels of CO 2 emissions efficiency and income. • Average industrial CO 2 emissions abatement cost for China’s major cities is 45 US$. - Abstract: Evaluating the energy and emissions efficiency, measuring the energy saving and emissions reduction potential, and estimating the carbon price in China at the regional level are considered a crucial way to identify the regional efficiency levels and efficiency promotion potentials, as well as to explore the marginal abatement costs of carbon emissions in China. This study applies a newly developed Data Envelopment Analysis (DEA) based method to evaluate the regional energy and emissions efficiencies and the energy saving and emissions reduction potentials of the industrial sector of 30 Chinese major cities during 2006–2010. In addition, the CO 2 shadow prices, i.e., the marginal abatement costs of CO 2 emissions from industrial sector of these cities are estimated during the same period. The main findings are: (i) The coast area cities have the highest total factor industrial energy and emissions efficiency, but efficiency of the west area cities are lowest, and there is statistically significant efficiency difference between these cities. (ii) Economically well-developed cities evidence higher efficiency, and there is still obviously unbalanced and inequitable growth in the nationwide industrial development of China. (iii) Fortunately, the energy utilization and CO 2 emissions efficiency gaps among different Chinese cities were decreasing since 2006, and the problem of inequitable nationwide development has started to mitigate.

Liu, Xiao; Leung, Yee; Xu, Yuan; Yung, Linda Chor Wing

2017-10-01

Carbon tax has been advocated as an effective economic instrument for the abatement of CO2 emission by various countries, including China, the world's biggest carbon emission country. However, carbon emission abatement cannot be done while ignoring the impact on economic growth. A delicate balance needs to be achieved between the two to find an appropriate pathway for sustainable development. This paper applies a multi-objective optimization approach to analyze the impact of levying carbon tax on the energy-intensive sectors of Guangdong province in China under the constraint of emission reduction target. This approach allows us to evaluate carbon emission minimization while maximizing GDP. For policy analysis, we construct five scenarios for evaluation and optimal choice. The results of the analysis show that a lower initial carbon tax rate is not necessarily better, and that a carbon tax is an effective means to reduce CO2 emissions while maintaining a certain level of GDP growth.

This study aims to estimate carbon intensity abatement potential in China at the regional level by proposing a particle swarm optimization–genetic algorithm (PSO–GA) multivariate environmental learning curve estimation method. The model uses two independent variables, namely, per capita gross domestic product (GDP) and the proportion of the tertiary industry in GDP, to construct carbon intensity learning curves (CILCs), i.e., CO 2 emissions per unit of GDP, of 30 provinces in China. Instead of the traditional ordinary least squares (OLS) method, a PSO–GA intelligent optimization algorithm is used to optimize the coefficients of a learning curve. The carbon intensity abatement potentials of the 30 Chinese provinces are estimated via PSO–GA under the business-as-usual scenario. The estimation reveals the following results. (1) For most provinces, the abatement potentials from improving a unit of the proportion of the tertiary industry in GDP are higher than the potentials from raising a unit of per capita GDP. (2) The average potential of the 30 provinces in 2020 will be 37.6% based on the emission's level of 2005. The potentials of Jiangsu, Tianjin, Shandong, Beijing, and Heilongjiang are over 60%. Ningxia is the only province without intensity abatement potential. (3) The total carbon intensity in China weighted by the GDP shares of the 30 provinces will decline by 39.4% in 2020 compared with that in 2005. This intensity cannot achieve the 40%–45% carbon intensity reduction target set by the Chinese government. Additional mitigation policies should be developed to uncover the potentials of Ningxia and Inner Mongolia. In addition, the simulation accuracy of the CILCs optimized by PSO–GA is higher than that of the CILCs optimized by the traditional OLS method. - Highlights: • A PSO–GA-optimized multi-factor environmental learning curve method is proposed. • The carbon intensity abatement potentials of the 30 Chinese provinces are estimated by

Highlights: • We developed a microwave plasma torch with reverse vortex reactor (RVR). • We calculated a volume fraction and temperature distribution of discharge gas and waste. • The performance of reverse vortex reactor increased from 29% to 43% than conventional vortex reactor. - Abstract: Abatement of fluorinated compounds (FCs) used in semiconductor and display industries has received an attention due to the increasingly stricter regulation on their emission. We have developed a 2.45 GHz microwave plasma torch with reverse vortex reactor (RVR). In order to design a reverse vortex plasma reactor, we calculated a volume fraction and temperature distribution of discharge gas and waste gas in RVR by ANSYS CFX of computational fluid dynamics (CFD) simulation code. Abatement experiments have been performed with respect to SF{sub 6}, NF{sub 3} by varying plasma power and N{sub 2} flow rates, and FCs concentration. Detailed experiments were conducted on the abatement of NF{sub 3} and SF{sub 6} in terms of destruction and removal efficiency (DRE) using Fourier transform infrared (FTIR). The DRE of 99.9% for NF{sub 3} was achieved without an additive gas at the N{sub 2} flow rate of 150 liter per minute (L/min) by applying a microwave power of 6 kW with RVR. Also, a DRE of SF{sub 6} was 99.99% at the N{sub 2} flow rate of 60 L/min using an applied microwave power of 6 kW. The performance of reverse vortex reactor increased about 43% of NF{sub 3} and 29% of SF{sub 6} abatements results definition by decomposition energy per liter more than conventional vortex reactor.

During missions to the Moon or Mars, the crew will need medical capabilities to diagnose and treat disease as well as for maintaining their health. The Exploration Medical Capability Element develops medical technologies, medical informatics, and clinical capabilities for different levels of care during space missions. The work done by team members in this Element is leading edge technology, procedure, and pharmacological development. They develop data systems that protect patient's private medical information, aid in the diagnosis of medical conditions, and act as a repository of relevant NASA life sciences experimental studies. To minimize the medical risks to crew health the physicians and scientists in this Element develop models to quantify the probability of medical events occurring during a mission. They define procedures to treat an ill or injured crew member who does not have access to an emergency room and who must be cared for in a microgravity environment where both liquids and solids behave differently than on Earth. To support the development of these medical capabilities, the Element manages the development of medical technologies that prevent, monitor, diagnose, and treat an ill or injured crewmember. The Exploration Medical Capability Element collaborates with the National Space Biomedical Research Institute (NSBRI), the Department of Defense, other Government-funded agencies, academic institutions, and industry.

Auto-vehicles and environment: Emission limits and innovative technology

International Nuclear Information System (INIS)

Pinchera, G.

1992-01-01

Brief descriptions are given of the main design and performance characteristics and maintenance requirements of the principal types of catalytic converters currently being marketed in Italy. An assessment is made of the contribution of these devices to air pollution abatement in Italy as car owners conform to recently passed stricter emission limits. A historical review is made of trends in auto-vehicle pollution limits in the USA and Italy. Comparisons are made of efforts by industrialized countries to reduce air pollution in the transportation sector. Here, the author notes the slowness of Italy's response to the air pollution problem, in particular, this foreign-oil-dependent Nation's over-emphasis on energy consuming and highly polluting road transport systems, as well as, its lack of technology utilization and commercialization in the pollution equipment sector. Suggestions are made as to ways to overcome the worsening situation with regard to urban area traffic derived air pollution, e.g., the bolstering of mass transit systems and more R ampersand D investment in pollution abatement technologies

2012-01-01

The first MCNP based in-line Monte Carlo depletion capability was officially released from the Radiation Safety Information and Computational Center as MCNPX 2.6.0. Both the MCNP5 and MCNPX codes have historically provided a successful combinatorial geometry based, continuous energy, Monte Carlo radiation transport solution for advanced reactor modeling and simulation. However, due to separate development pathways, useful simulation capabilities were dispersed between both codes and not unified in a single technology. MCNP6, the next evolution in the MCNP suite of codes, now combines the capability of both simulation tools, as well as providing new advanced technology, in a single radiation transport code. We describe here the new capabilities of the MCNP6 depletion code dating from the official RSICC release MCNPX 2.6.0, reported previously, to the now current state of MCNP6. NEA/OECD benchmark results are also reported. The MCNP6 depletion capability enhancements beyond MCNPX 2.6.0 reported here include: (1) new performance enhancing parallel architecture that implements both shared and distributed memory constructs; (2) enhanced memory management that maximizes calculation fidelity; and (3) improved burnup physics for better nuclide prediction. MCNP6 depletion enables complete, relatively easy-to-use depletion calculations in a single Monte Carlo code. The enhancements described here help provide a powerful capability as well as dictate a path forward for future development to improve the usefulness of the technology. (authors)

Biomass for electricity in the EU-27: Potential demand, CO2 abatements and breakeven prices for co-firing

International Nuclear Information System (INIS)

Bertrand, Vincent; Dequiedt, Benjamin; Le Cadre, Elodie

2014-01-01

This paper analyses the potential of biomass-based electricity in the EU-27 countries, and interactions with climate policy and the EU ETS. We estimate the potential biomass demand from the existing power plants, and we match our estimates with the potential biomass supply in Europe. Furthermore, we compute the CO2 abatement associated with the co-firing opportunities in European coal plants. We find that the biomass demand from the power sector may be very high compared with potential supply. We also identify that co-firing can produce high volumes of CO 2 abatements, which may be two times larger than that of the coal-to-gas fuel switching. We also compute biomass and CO2 breakeven prices for co-firing. Results indicate that biomass-based electricity remains profitable with high biomass prices, when the carbon price is high: a Euros 16–24 (25–35, respectively) biomass price (per MWh prim ) for a Euros 20 (50, respectively) carbon price. Hence, the carbon price appears as an important driver, which can make profitable a high share of the potential biomass demand from the power sector, even with high biomass prices. This aims to gain insights on how biomass market may be impacted by the EU ETS and others climate policies. - Highlights: • Technical potential of biomass (demand and CO 2 abatement) in European electricity. • Calculation for co-firing and biomass power plants; comparison with potential biomass supply in EU-27 countries. • Calculation of biomass and CO 2 breakeven prices for co-firing. • Potential demand is 8–148% of potential supply (up to 80% of demand from co-firing). • High potential abatement from co-firing (up to 365 Mt/yr); Profitable co-firing with €16-24 (25–35) biomass price for €20 (50) CO 2 price

This paper estimates the economic returns to carbon abatement through biological sequestration in community managed forest under future REDD policy, and compares these for three possible management scenarios. For the estimation, the research relies on forest inventory data together with other socio-economic and resources use data collected from forest users in three sites of Nepal Himalaya. The paper estimates the incremental carbon from forest enhancement on a yearly basis over a five-year period using the value of 1 and 5 per tCO{sub 2} for conservative analysis. The results based on the three sites indicate that community forest management may be one of the least cost ways to abate carbon with a break-even price under Scenario 2 which ranges from 0.55 to 3.70 per tCO{sub 2}. However, bringing community forests into the carbon market may entail high opportunity costs as forests provide numerous non-monetary benefits to the local population, who regard these as the main incentive for conservation and management. An important finding of the research is that if forest resources use by local communities is not permitted, then carbon trading will not be attractive to them as revenue from carbon will not cover the cost foregone by not harvesting forest resources.

Building IT capability in health-care organizations.

Khatri, Naresh

2006-05-01

While computer technology has revolutionized industries such as banking and airlines, it has done little for health care so far. Most of the health-care organizations continue the early-computer-era practice of buying the latest technology without knowing how it might effectively be employed in achieving business goals. By investing merely in information technology (IT) rather than in IT capabilities they acquire IT components--primarily hardware, software, and vendor-provided services--which they do not understand and, as a result, are not capable of fully utilizing for achieving organizational objectives. In the absence of internal IT capabilities, health-care organizations have relied heavily on the fragmented IT vendor market in which vendors do not offer an open architecture, and are unwilling to offer electronic interfaces that would make their 'closed' systems compatible with those of other vendors. They are hamstrung as a result because they have implemented so many different technologies and databases that information stays in silos. Health systems can meet this challenge by developing internal IT capabilities that would allow them to seamlessly integrate clinical and business IT systems and develop innovative uses of IT. This paper develops a comprehensive conception of IT capability grounded in the resource-based theory of the firm as a remedy to the woes of IT investments in health care.

Impact of electric range and fossil fuel price level on the economics of plug-in hybrid vehicles and greenhouse gas abatement costs

International Nuclear Information System (INIS)

Özdemir, Enver Doruk; Hartmann, Niklas

2012-01-01

In this paper, the energy consumption shares of plug-in hybrid vehicles (PHEVs) for electricity from the grid and conventional fuel depending on electric driving range are estimated. The resulting mobility costs and greenhouse gas (GHG) abatement costs per vehicle kilometer for the year 2030 are calculated and optimal electric driving range (which indicates the size of the battery) is found for different oil price levels with the help of a MATLAB based model for a typical compact passenger car (e.g. VW Golf). The results show that the optimum electric driving range for minimum mobility costs of a PHEV is between 12 and 32 km. Furthermore, optimum GHG abatement costs are achieved with an electric driving range between 16 and 23 km. These results are considerable lower than most market ready PHEVs (electric driving range of 50 to 100 km), which shows that the automobile industry should concentrate on shorter electric driving range for PHEVs in the near future to offer cost optimum mobility and low GHG abatement costs. However, the oil price level and the consumer driving habits impact heavily on the cost performance as well as the optimum electric driving range of plug-in hybrid vehicles. - Highlights: ► We analyze the energy consumption (and share of grid electricity) of plug-in hybrid vehicles. ► We analyzed the mobility costs and GHG abatement costs depending on electric driving range. ► Mobility costs of plug-in hybrid vehicles can be lower than those of conventional diesel vehicles in 2030. ► The optimum mobility costs are achieved with the electric driving range between 12 and 32 km. ► The optimum GHG abatement costs are achieved with the electric driving range between 16 and 23 km.

1961-01-01

The authors used gamma cardiology during the abatement of 16 cases of asthma with a view to detecting heart attacks not otherwise visible with routine methods of examination: clinical, radiological and electro-cardio-graphical. In gamma cardiology, a radioactive indicator is used and its path followed in the cavities of the heart. The method makes it possible to study the circulation in the right heart, the pulmonary crossing, and the left heart, as well as evaluation of the heart-flow. As a result of their investigations the authors, after having discussed the significance of the data obtained with the method, suggest that it is possible by the use of gamma cardiography during the abatement of an asthma attack: 1- To confirm attacks of the right heart which have already been detected by ordinary methods. 2- To confirm the presence of modifications in the recorded curves which suggest, in the case of the left heart, possible attack; such on attack is also indicated, in a small number of cases, by electrocardiography curves. Some considerations are put forward by the authors concerning the physiopathology of attacks on the left heart. (authors) [fr

Abating coal tar seepage into surface water bodies using sheet piles with sealed interlocks

International Nuclear Information System (INIS)

Collingwood, B.I.; Boscardin, M.D.; Murdock, R.F.

1995-01-01

A former coal tar processing facility processed crude coal tar supplied from manufactured gas plants in the area. Coal-tar-contaminated ground water from the site was observed seeping through an existing timber bulkhead along a tidal river and producing a multicolored sheen on the surface of the river. As part of a short-term measure to abate the seepage into the river, 64-m long anchored sheet pile wall with sheet pile wing walls at each end was constructed inland of the of the timber bulkhead. The sheet piles extended to low-permeability soils at depth and the interlocks of the sheet piles were provided with polyurethane rubber seals. Based on postconstruction observations for leakage and sheens related to leakage, the steel sheet piles with polyurethane rubber interlock seals appeared to provide a successful seal and abate coal-tar-contaminated ground water seepage into the river. The tie rod penetration sealing proved to be a more problematic detail, but through several postconstruction grouting episodes, an effective seal was produced

Gonzalez, Oscar; Sans, Carme; Esplugas, Santiago

2007-01-01

The objective of this work was to study the abatement of 200 mg L -1 sulfamethoxazole (SMX) solution by means of photo-Fenton process. Biodegradability of the treated solutions was followed by the ratio biochemical oxygen demand at five days/chemical oxygen demand (BOD 5 /COD) and toxicity by Microtox[reg] and inhibition tests. Experiments with different initial concentration of H 2 O 2 were carried out. The initial amount of Fe 2+ and pH of the solution were set at 10 mg L -1 and 2.8 respectively. The temperature of the reactor was kept constant in all the experiments (25 ± 0.8 deg. C). Photo-Fenton process is thought to be a successful treatment step to improve the biodegradability of wastewater containing SMX. The complete antibiotic removal was achieved for a H 2 O 2 dose over 300 mg L -1 . Biodegradability (BOD 5 /COD) rose from zero (SMX solution) to values higher than 0.3 (treated solutions). Toxicity and inhibition tests pointed out in the same direction: oxidized intermediates for initial H 2 O 2 dose over 300 mg L -1 showed no toxicity effects on pure bacteria and no inhibition on activated sludge activity

This paper introduces a solution for the fair division of emission reduction costs in the climate change regime. Our primary focus is on the fair division of efficiency gains that arise from exchanging the initial allocation of emission entitlements, rather than the initial allocation itself. We propose to complement the competitive Walrasian solution with welfare bounds, the ethical justification of which rests on commonality of ownership. Simulations with an intertemporal computable general equilibrium model illustrate the relevance of such welfare bounds. For a wide range of initial allocations of emission entitlements - including an equal per capita allocation - we find that developing countries should be fully compensated for their emission abatement efforts, but should not receive any further transfers.

Highlights: • A fungal biofilter/photoreactor was evaluated in terms of hexane and spore removal. • Biofilter supported elimination capacities of ≈35 g m{sup −3} h{sup −1} and CO{sub 2} yields of ≈75%. • The photocatalytic process slightly boosted the hexane abatement performance. • Biofilter emitted fungal spores at concentrations of 2.4 × 10{sup 3}–9.0 × 10{sup 4} CFU m{sup −3}. • Photo-assisted post-treatments resulted in spore deactivation efficiencies of 98%. - Abstract: The performance of a fungal perlite-based biofilter coupled to a post-treatment photoreactor was evaluated over 234 days in terms of n-hexane removal, emission and deactivation of fungal spores. The biofilter and photoreactor were operated at gas residence times of 1.20 and 0.14 min, respectively, and a hexane loading rate of 115 ± 5 g m{sup −3} h{sup −1}. Steady n-hexane elimination capacities of 30–40 g m{sup −3} h{sup −1} were achieved, concomitantly with pollutant mineralization efficiencies of 60–90%. No significant influence of biofilter irrigation frequency or irrigation nitrogen concentration on hexane abatement was recorded. Photolysis did not support an efficient hexane post-treatment likely due to the short EBRT applied in the photoreactor, while overall hexane removal and mineralization enhancements of 25% were recorded when the irradiated photoreactor was packed with ZnO-impregnated perlite. However, a rapid catalyst deactivation was observed, which required a periodic reactivation every 48 h. Biofilter irrigation every 3 days supported fungal spore emissions at concentrations ranging from 2.4 × 10{sup 3} to 9.0 × 10{sup 4} CFU m{sup −3}. Finally, spore deactivation efficiencies of ≈98% were recorded for the photolytic and photocatalytic post-treatment processes. This study confirmed the potential of photo-assisted post-treatment processes to mitigate the emission of hazardous fungal spores and boost the abatement performance of

Application of cheaper materials in pollution abatement

1997-01-01

Industrial effluents and waste water bearing toxic metal ions and hazardous organic substances including phenols and dyes need to be treated to remove such harmful materials before their safe disposal into biosphere. For this purpose a number of cheaper and waste materials like onion skin, bagasse pith, maize ob, groundnut husk, saw dust, wood, fugal and biomass, biogas waste slurry, lignite, wool fiber, fly ash, blast furnace sludge peat and charcoal, natural clays, sands and minerals, bone and glass have been used. some of these materials can also be employed to decontaminate fresh water containing these harmful substances present in very low concentrations. These cheaper materials have been reviewed and examples have been cited mostly from the recent literature. the optimal conditions for the removal of hazardous substances including metal ions form solutions utilizing these waste materials have also been given. These low cost materials have been proven to be very effective in the spheres of pollution abatement and environmental studies. (author)

Highlights: • Improving productivity was the most effective strategy to reduce emissions and costs. • The accounting methods disagreed on the total abatement potential of mitigation measures. • Thus, it may be difficult to convince farmers to adopt certain abatement measures. • Domestic offsetting and consumption based accounting are options to overcome current methodological issues. - Abstract: Marginal abatement cost curve (MACC) analysis allows the evaluation of strategies to reduce agricultural greenhouse gas (GHG) emissions relative to some reference scenario and encompasses their costs or benefits. A popular approach to quantify the potential to abate national agricultural emissions is the Intergovernmental Panel on Climate Change guidelines for national GHG inventories (IPCC-NI method). This methodology is the standard for assessing compliance with binding national GHG reduction targets and uses a sector based framework to attribute emissions. There is however an alternative to the IPCC-NI method, known as life cycle assessment (LCA), which is the preferred method to assess the GHG intensity of food production (kg of GHG/unit of food). The purpose of this study was to compare the effect of using the IPCC-NI and LCA methodologies when completing a MACC analysis of national agricultural GHG emissions. The MACC was applied to the Irish agricultural sector and mitigation measures were only constrained by the biophysical environment. The reference scenario chosen assumed that the 2020 growth targets set by the Irish agricultural industry would be achieved. The comparison of methodologies showed that only 1.1 Mt of the annual GHG abatement potential that can be achieved at zero or negative cost could be attributed to agricultural sector using the IPCC-NI method, which was only 44% of the zero or negative cost abatement potential attributed to the sector using the LCA method. The difference between methodologies was because the IPCC-NI method attributes the

The use of removable thin films for the abatement of hazardous particulates has many advantages. Removable thin films are designed to trap and fix particulates in the film's matrix by adhesion. Thin films can be applied to an existing contaminated area to fix and capture the particulates for removal. The nature of the removable thin films, after sufficient cure time, is such that it can typically be removed as one continuous entity. The removable thin films can be applied to almost any surface type with a high success rate of removal

2012-01-01

With the abatement potential of end-of-pipe technologies for road transport becoming increasingly marginal, and with greater emissions reductions still needed in order to reduce pollution, alternative strategies involving behavioural change and choices between fossil fuelled or low carbon vehicles becomes more important. The environmental requirements include local air quality objectives, meeting national emissions ceilings to limit transboundary effects, and to aspire to significant reductions in greenhouse gas emissions. In this paper we use the BRUTAL sub-model of the UK integrated Assessment Model (UKIAM) to investigate a selection of alternative strategies including downsizing of cars, switching from petrol to diesel, and the introduction of electric, bio-fuelled or hydrogen vehicles into the fleet, relative to a business-as-usual projection for 2020. Projected impacts upon air quality limit values, national emissions ceilings and CO 2 emissions are assessed in relation to local, national and international objectives. We discuss related life-cycle impacts, implications for infrastructure, and potential impacts upon emissions from other sectors in order to highlight the full potential implications of the different strategies within the context of changes resulting from other policy developments at different scales.

N 2 O represents ∼6% of the global greenhouse gas emission inventory and the most important O 3 -depleting substance emitted in this 21st century. Despite its environmental relevance, little attention has been given to cost-effective and environmentally friendly N 2 O abatement methods. Here we examined, the potential of a bubble column (BCR) and an internal loop airlift (ALR) bioreactors of 2.3 L for the abatement of N 2 O from a nitric acid plant emission. The process was based on the biological reduction of N 2 O by Paracoccus denitrificans using methanol as a carbon/electron source. Two nitrogen limiting strategies were also tested for the coproduction of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) coupled with N 2 O reduction. High N 2 O removal efficiencies (REs) (≈87%) together with a low PHBV cell accumulation were observed in both bioreactors in excess of nitrogen. However, PHBV contents of 38-64% were recorded under N limiting conditions along with N 2 O-REs of ≈57% and ≈84% in the ALR and BCR, respectively. Fluorescence in situ hybridization analyses showed that P. denitrificans was dominant (>50%) after 6 months of experimentation. The successful abatement of N 2 O concomitant with PHBV accumulation confirmed the potential of integrating biorefinery concepts into biological gas treatment for a cost-effective GHG mitigation.

The first stage of the study was to make a preliminary inventory of greenhouse gas (GHG) emissions for the base year 1988. Following this seven no regret technical options for emission reduction were investigated and the costs calculated, allowing the identification of three least-cost options. The three least-cost options must be implemented first because of their negative costs. The economic benefits of both abatement scenarios are characterized by a negative global cost whatever the discount rate is. (author)

Estimating the financial risks of Andropogon gayanus to greenhouse gas abatement projects in northern Australia

Financial mechanisms such as offsets are one strategy to abate greenhouse gas emissions, and the carbon market is expanding with a growing demand for offset products. However, in the case of carbon offsets, if the carbon is released due to intentional or unintentional reversal through environmental events such as fire, the financial liability to replace lost offsets will likely fall on the provider. This liability may have implications for future participation in programmes, but common strategies such as buffer pool and insurance products can be used to minimize this liability. In order for these strategies to be effective, an understanding of the spatial and temporal distributions of expected reversals is needed. We use the case study of savanna burning, an approved greenhouse gas abatement methodology under the Carbon Farming Initiative in Australia, to examine potential risks to carbon markets in northern Australia and quantify the financial risks. We focus our analysis on the threat of Andropogon gayanus (gamba grass) to savanna burning due to its documented impacts of increased fuel loads and altered fire regimes. We assess the spatial and financial extent to which gamba grass poses a risk to savanna burning programmes in northern Australia. We find that 75% of the eligible area for savanna burning is spatially coincident with the high suitability range for gamba grass. Our analysis demonstrates that the presence of gamba grass seriously impacts the financial viability of savanna burning projects. For example, in order to recuperate the annual costs of controlling 1 ha of gamba grass infestation, 290 ha of land must be enrolled in annual carbon abatement credits. Our results show an immediate need to contain gamba grass to its current extent to avoid future spread into large expanses of land, which are currently profitable for savanna burning.

The UNEP (United Nations Environment Programme) programme of Greenhouse Gas Abatement Costing Studies is intended to clarify the economic issues involved in assessing the costs of limiting emissions of greenhouse gases and to propose approaches to comparable costing studies. Phase 1 of the Zimbabwe country study describes the current energy situation in Zimbabwe related to the national economy, energy supply and demand and amounts of greenhouse gas emissions. Factors regarding the geography, (including a map illustrating the degree and character of land degradation by erosion) population, politics, international relations, land-use and management of the energy sector are dealt with in detail and the text is illustrated with data compiled from the study. It is estimated that Zimbabwe consumed 270.4 Tj of energy during 1988 and emitted 21.7 tonnes of carbon dioxide. An emission intensity of 80.2 tonnes/Tj for the whole economy and 63.6 tonnes/Tj for electric power generation alone was calculated. Forecasting for the year 2020 estimated carbon dioxide emission intensities of 73.5 tonnes/Tj for the whole economy and 43.7 tonnes for power generation. Net carbon dioxide emissions are predicted to be 30-42 tonnes during 2020. (AB).

Exploring the 'permanent forest' paradigm: might renewable commercial forest estates lead to greater net greenhouse abatement over the longer term?

International Nuclear Information System (INIS)

Anderson, Graeme

2007-01-01

Full text: Understanding permanence: A common perception exists which suggests that long term or 'permanent' tree plantings are considered a superior form of (post 1990) carbon sink, and commercial plantations (which allow for harvesting and replanting) are less useful for abatement. However, common to all forms of forest carbon sink is the issue of permanence. None of these are truly permanent stores of carbon because at any point either a fire, disease, harvest or major event can mean part of the carbon store is released. Why then the perceived bias against sink projects which allow for commercial harvesting and replanting? Let's not forget - things are getting hotter: Australian projections for climate change provide plenty of challenges for current and future forest managers. Over the next century many key forest species may have to endure conditions outside their'current growing range. This poses risks for the emergent offsets industry which needs to be actively managed. Simply planting local indigenous species alone may no longer be the only best practice. Think 'true fate of carbon': It is important that our thinking is not constrained by current rules, as these will continually be refined as our knowledge about carbon systems improves over the next century (between now and 2100 there will be 22 post-Kyoto negotiation periods). Our key focus should be in considering the 'true fate' of carbon, and the real contribution to greenhouse abatement. Policy makers need to keep this in mind, and ensure that the entire carbon life cycle is considered in their decision making. 'Standing forest' versus 'Net abatement effect': There are two effective means for forests to achieve genuine greenhouse abatement. One is the carbon sequestered and stored in the 'standing forest', the other is the greenhouse benefit (carbon flow or net abatement effect) of an ongoing and renewable supply of tree based products from the site (wood, fibre, biomass, biofuel), which replace

Energy balance and GHG-abatement cost of cassava utilization for fuel ethanol in Thailand

International Nuclear Information System (INIS)

Nguyen, Thu Lan Thi; Gheewala, Shabbir H.; Garivait, Savitri

2007-01-01

Since 2001, in order to enhance ethanol's cost competitiveness with gasoline, the Thai government has approved the exemption of excise tax imposed on ethanol, controlling the retail price of gasohol (a mixture of ethanol and gasoline at a ratio of 1:9) to be less than that of octane 95 gasoline, within a range not exceeding 1.5 baht a litre. The policy to promote ethanol for transport is being supported by its positive effects on energy security and climate change mitigation. An analysis of energy, greenhouse gas (GHG) balances and GHG abatement cost was done to evaluate fuel ethanol produced from cassava in Thailand. Positive energy balance of 22.4 MJ/L and net avoided GHG emission of 1.6 kg CO 2 eq./L found for cassava-based ethanol (CE) proved that it would be a good substitute for gasoline, effective in fossil energy saving and GHG reduction. With a GHG abatement cost of US$99 per tonne of CO 2 , CE is rather less cost effective than the many other climate strategies relevant to Thailand in the short term. Opportunities for improvements are discussed to make CE a reasonable option for national climate policy

Science, Technology and Innovation as Social Goods for Development: Rethinking Research Capacity Building from Sen's Capabilities Approach.

Science.gov (United States)

Mormina, Maru

2018-03-01

Science and technology are key to economic and social development, yet the capacity for scientific innovation remains globally unequally distributed. Although a priority for development cooperation, building or developing research capacity is often reduced in practice to promoting knowledge transfers, for example through North-South partnerships. Research capacity building/development tends to focus on developing scientists' technical competencies through training, without parallel investments to develop and sustain the socioeconomic and political structures that facilitate knowledge creation. This, the paper argues, significantly contributes to the scientific divide between developed and developing countries more than any skills shortage. Using Charles Taylor's concept of irreducibly social goods, the paper extends Sen's Capabilities Approach beyond its traditional focus on individual entitlements to present a view of scientific knowledge as a social good and the capability to produce it as a social capability. Expanding this capability requires going beyond current fragmented approaches to research capacity building to holistically strengthen the different social, political and economic structures that make up a nation's innovation system. This has implications for the interpretation of human rights instruments beyond their current focus on access to knowledge and for focusing science policy and global research partnerships to design approaches to capacity building/development beyond individual training/skills building.

Full Text Available Resumen:En este artículo interesa determinar la estructura lógica del concepto de capacidades tecnológicas para establecer las características y los componentes más relevantes, esto con la intención de proponer una definición filosófica a partir de las ideas de capacidades y funcionamientos de Amartya Sen y del concepto de disposiciones de Gilbert Ryle. Se trata de una ampliación o aplicación de esas nociones a la idea de capacidades tecnológicas con el fin de obtener dicho concepto operativo y apropiado. El estudio se lleva a cabo, porque la noción de capacidades tecnológicas es muy utilizada en diversos textos de economía, administración, tecnología y filosofía, pero sin que se las defina apropiadamente ni se les fundamente filosóficamente. La investigación en la que se sustenta el artículo se realizó en el año 2005 con un enfoque de análisis inscrito en la tradición filosófica analítica.Abstract:In this work I am interested in determining the logical structure of the concept of technological capabilities to establish their characteristics and components. This is done with the intention of proposing an operative definition of such a notion. For this purpose I proceed to establish its theoretical foundation, inspired in Amartya Sen’s conception of capability and operation, as well as in Ryle's concept of disposition. It is an amplification or application from those notions to the idea of technological capability in order to obtain an operative and appropriate notion. An exploration of the notion of tecnological capabilities seems very timely because of its widespread use in economics, business administration and philosophy, areas in which both a clear definition and a theoretical explanation are usually missing. The research for this paper took place in 2005, when its author was working for his Ph.D. at the Carlos III University in Madrid. Our approach here is typical of the analytical tradition in philosophy.

Highlights: ► We employ a slacks-based DEA model to estimate the energy efficiency and shadow prices of CO 2 emissions in China. ► The empirical study shows that China was not performing CO 2 -efficiently. ► The average of estimated shadow prices of CO 2 emissions is about $7.2. -- Abstract: This paper uses nonparametric efficiency analysis technique to estimate the energy efficiency, potential emission reductions and marginal abatement costs of energy-related CO 2 emissions in China. We employ a non-radial slacks-based data envelopment analysis (DEA) model for estimating the potential reductions and efficiency of CO 2 emissions for China. The dual model of the slacks-based DEA model is then used to estimate the marginal abatement costs of CO 2 emissions. An empirical study based on China’s panel data (2001–2010) is carried out and some policy implications are also discussed.

Decomposing the impact of alternative technology sets on future carbon emissions growth

Fisher-Vanden, Karen; Schu, Kathryn; Sue Wing, Ian; Calvin, Katherine

2012-01-01

What are the drivers of future global carbon dioxide (CO 2 ) emissions growth and how would the availability of key energy supply technologies change their relative importance? In this paper, we apply a novel index number decomposition technique to the results of a multi-region, multi-sector computable general equilibrium model to quantify the influence of five factors on the growth of future carbon emissions: (1) growth in global economic activity; (2) shifts in the regional composition of gross world product; (3) shifts in the sectoral composition of regions' GDP; (4) changes in sectors' energy–output ratios; and (5) changes in the CO 2 intensity of energy sources. We elucidate how the relative importance of these factors changes in response to the imposition of a global carbon tax and alternative assumptions about the future availability of key energy supply technologies. Rising global economic activity and shifts in regional composition put upward pressure on emissions while changes in energy and emission intensity and the sectoral output mix have attenuating effects. A global emission tax that increases over time slows economic expansion and shifts the fuel mix, with the most pronounced impacts on China, India, and Russia. Limited availability of carbon capture and storage, nuclear, and hydroelectric generation all lead to upward shifts in the long-run marginal abatement cost curve, causing some countries to choose to pay the tax rather than abate. - Highlights: ► Index number decomposition is used to quantify the influence of five factors. ► The relative importance of these factors in response to alternative assumptions is measured. ► A global emission tax that increases over time slows economic expansion and shifts the fuel mix. ► Limited technology availability mean some countries to choose to pay the tax rather than abate.

“Coupled processes” as dynamic capabilities in systems integration

Milton de Freitas Chagas Jr.

2017-05-01

Full Text Available The dynamics of innovation in complex systems industries is becoming an independent research stream. Apart from conventional uncertainties related to commerce and technology, complex-system industries must cope with systemic uncertainty. This paper’s objective is to analyze evolving technological paths from one product generation to the next through two case studies in the Brazilian aerospace indus­try, considering systems integration as an empirical instantiation of dynamic capabilities. A proposed “coupled processes” model intertwines two organizational processes regarded as two levels of dynamic capabilities: new product and technological developments. The model addresses the role of emergent properties in shaping a firm’s technological base. Moreover, it uses a technology readiness level to unveil systems integration business tricks and as a decision-making yardstick. The “coupled processes” model is revealed as a set of dynamic capabilities presenting ambidexterity in complex systems indus­tries, a finding that may be relevant for newly industrialized economies.

Building sustainable knowledge management capabilities in the coastal area might face a whole new challenge since there are many intangible factors involved from openness on new knowledge, access and ability to use the latest technology to the various local wisdom that still in place. The aimed of this study was to identify and analyze the resource-based condition of coastal community in this area to have an empirical condition of tangible and intangible infrastructure on developing knowledge management capability coastal community in Southeast Maluku, Indonesia. We used qualitative and quantitative analysis by depth interview and questionnaire for collecting the data with multiple linear regression as our analysis method. The result provided the information on current state of resource-based capability of a coastal community in this Southeast Maluku to build a sustainability model of knowledge management capabilities especially on utilization marine and fisheries resources. The implication of this study can provide an empirical information for government, NGO and research institution to dictate on how they conducted their policy and program on developing coastal community region.

Energy-saving behavior and marginal abatement cost for household CO2 emissions

International Nuclear Information System (INIS)

Hamamoto, Mitsutsugu

2013-01-01

This paper attempts to measure consumers' perceived net benefits (or net costs) of energy-saving measures in using energy-consuming durable goods. Using the estimated net costs and the volume of CO 2 reduced by the measures, a marginal abatement cost (MAC) curve for the average household's CO 2 emissions is produced. An analysis using the curve suggests that in order to provide households with an incentive to take actions that can lead to CO 2 emission reductions in using energy-consuming durables, a high level of carbon price is needed. In addition, a regression analysis reveals that the net benefits of the measures are larger for households that put a higher priority on energy saving, for those living in detached houses, for those with a smaller number of persons living together, and for those with less income. The result of the analysis using the MAC curve may suggest that promoting energy-saving behavior will require not only a policy to provide economic incentives but also interventions to influence psychological factors of household behavior. - Highlights: • Consumers' perceived net costs of energy-saving measures in using energy-consuming durables are measured. • Using the estimated net costs, a marginal abatement cost (MAC) curve for the average household's CO 2 emissions is produced. • A high carbon price is needed in order to provide households with an incentive to take actions for energy-savings. • Households' attributes affecting their energy-saving behavior are revealed by a regression analysis

Advanced clean coal utilization technologies

The most important greenhouse gas is CO{sub 2} from coal utilization. Ways of mitigating CO{sub 2} emissions include the use of alternative fuels, using renewable resources and increasing the efficiency of power generation and end use. Adding to such greenhouse gas mitigation technologies, post combustion control by removing CO{sub 2} from power station flue gases and then storing or disposing it will be available. Although the post combustion control have to be evaluated in a systematic manner relating them to whether they are presently available technology, to be available in the near future or long term prospects requiring considerable development, it is considered to be a less promising option owing to the high cost and energy penalty. By contrast, abatement technologies aimed at improving conversion efficiency or reducing energy consumption will reduce emissions while having their own commercial justification.

2002-06-01

Full Text Available Grupos de caprinos mestiços castrados e inteiros foram abatidos com idades de 175, 220, 265 e 310 dias. Os efeitos da castração e idade de abate nas qualidades físico-químicas, sensoriais e aromáticos da carne caprina foi pesquisado. O efeito castração foi observado apenas para o conteúdo de cálcio, no entanto a idade de abate apresentou um efeito significativo nos teores de umidade, proteína, cálcio, ferro e pH. Os fatores idade de abate e castração não apresentaram efeito significativo nos percentuais de fosfolipídeos porém, a idade de abate afetou os percentuais de colesterol. Caprinos castrados apresentaram maior percentual de ácidos graxos insaturados e, conseqüentemente, maior relação PUFA/SFA. Os ácidos graxos foram afetados significativamente pela castração. Não foram observadas variações nos percentuais dos ácidos graxos saturados e insaturados da carne caprina de animais abatidos com diferentes idades. O fator idade de abate apresentou maior efeito nos atributos sensoriais analisados do que o fator castração. Nos extratos da carne caprina foram identificados um total de cento e oito voláteis, sendo estes: 41 hidrocarbonetos alifáticos, 12 hidrocarbonetos alicíclicos, 19 aldeídos, 9 compostos benzênicos, 9 álcoois, 7 cetonas, 4 compostos sulfurados, 2 terpenoídes, 2 ésteres e 3 outros compostos. Os extratos da carne de caprinos castrados continham maior número de compostos voláteis do que os extratos de animais inteiros. O fator idade de abate foi o parâmetro que mais afetou as características físico-químicas e sensoriais da carne caprina. O fator castração afetou diretamente a produção de voláteis.

2010-01-01

The 2010 'Capability Review' process at LANL significantly differs from the Division reviews of prior years. The Capabilities being reviewed (some 4-8 per year) are deliberately chosen to be crosscutting over the Laboratory, and therefore will include not only several experimental, theoretical and simulation disciplines, but also contributions from multiple line organizations. This approach is consistent with the new Laboratory organizational structure, focusing on agile and integrated capabilities applied to present national security missions, and also nurtured to be available for rapid application to future missions. The overall intent is that the Committee assess the quality of the science, engineering, and technology identified in the agenda, and advise the LANS Board of Governors and Laboratory management. Specifically, the Committees will: (1) Assess the quality of science, technology and engineering within the Capability in the areas defined in the agenda. Identify issues to develop or enhance the core competencies within this capability. (2) Evaluate the integration of this capability across the Laboratory organizations that are listed in the agenda in terms of joint programs, projects, proposals, and/or publications. Describe the integration of this capability in the wider scientific community using the recognition as a leader within the community, ability to set research agendas, and attraction and retention of staff. (3) Assess the quality and relevance of this capability's science, technology and engineering contributions to current and emerging Laboratory programs, including Nuclear Weapons, Threat Reduction/Homeland Security, and Energy Security. (4) Advise the Laboratory Director/Principal Associate Director for Science, Technology and Engineering on the health of the Capability including the current and future (5 year) science, technology and engineering staff needs, mix of research and development activities, program opportunities

Highlights: • Hydrothermal synthesis and characterization of Ce doped ZnO. • The abatement of ACE K is assessed in ultrapure water and in river water matrix. • Demonstrated higher degradation activity than P25 under visible light. • The degradation activity is less affected in river water than for P25. - Abstract: In the present study, we investigated the possibility to abate Acesulfame K, a persistent emerging contaminant, in aqueous media using zinc oxide based materials. For this purpose, bare and Ce-doped zinc oxide was prepared via an easy and cheap hydrothermal process using different cerium salts as precursors. Their photocatalytic performance was evaluated in different media, namely ultrapure and river water under both UV–vis and visible light. Commercial TiO_2 P25 was also employed and used as a reference photocatalyst for comparison purposes. The obtained results pointed out that cerium doped zinc oxide composites exhibit higher performance than TiO_2 P25, especially under visible light and in the presence of organic matter, when the activity of the latter is greatly depressed. In particular, ZnO doped with cerium (1%) was the most effective material, and could be a promising alternative to TiO_2 P25, especially in the treatment of natural waters.

Energy and water are two increasingly correlated resources. Electricity generation at thermoelectric power plants requires cooling such that large water withdrawal and consumption rates are associated with electricity consumption. Drinking water and wastewater treatment require significant electricity inputs to clean, disinfect, and pump water. Due to this energy-water nexus, energy efficiency measures might be a cost-effective approach to reducing water use and water efficiency measures might support energy savings as well. This research characterizes the cost-effectiveness of different efficiency approaches in households by quantifying the direct and indirect water and energy savings that could be realized through efficiency measures, such as low-flow fixtures, energy and water efficient appliances, distributed generation, and solar water heating. Potential energy and water savings from these efficiency measures was analyzed in a product-lifetime adjusted economic model comparing efficiency measures to conventional counterparts. Results were displayed as cost abatement curves indicating the most economical measures to implement for a target reduction in water and/or energy consumption. These cost abatement curves are useful in supporting market innovation and investment in residential-scale efficiency.

Evaluation of plume potential and plume abatement of evaporative cooling towers in a subtropical region

Hong Kong is a typical subtropical region with frequently high humidity in late spring and summer seasons. Plume from evaporative cooling towers, which service air-conditioning systems of civil buildings, has aroused public concerns since 2000 when the fresh water evaporative cooling towers were allowed to be used for high energy efficiency and environmental issues. This paper presents the evaluation of the plume potential and its effect on the sizing of the plume abatement system in a large commercial office building in Hong Kong for practical application. This evaluation was conducted based on a dynamic simulation platform using the typical meteorological year of Hong Kong since the occurrence of the plume heavily depends on the state conditions of the exhaust air from cooling towers and the ambient air, while the state condition of the exhaust air is determined by the total building cooling load and the control strategies of cooling towers employed mainly for improving energy efficiency. The results show that the control strategies have a significant effect on the plume potential and further affect the system design and sizing of the plume abatement system

Solar energy and the abatement of atmospheric emissions

In spite of the fact that solar energy is a ''clean'' energy form, gaseous pollutants are emitted during the manufacturing of the systems necessary for its utilisation. An attempt is made in this paper to estimate the level of atmospheric pollutants emitted during the successive stages which make up the manufacture process for solar water heating (SWH) systems, and to evaluate these results in comparison with the respective pollutant emission levels attributed to the generation of electricity in Greece's conventional power plants. As energy consumption is recognised as the main source of atmospheric pollution, a Life Cycle Analysis (LCA) method was applied, focusing on the most energy-consuming stages of the SWH system production process. The conclusions of the analysis indicate that the emissions of gaseous pollutants associated with the utilisation of solar energy are considerably lower than those caused by the production of electricity in conventional systems, thereby substantiating that solar energy utilisation can make a notable contribution to the abatement of atmospheric pollution.

Archiving Software Systems: Approaches to Preserve Computational Capabilities

A great deal of effort is made to preserve scientific data. Not only because data is knowledge, but it is often costly to acquire and is sometimes collected under unique circumstances. Another part of the science enterprise is the development of software to process and analyze the data. Developed software is also a large investment and worthy of preservation. However, the long term preservation of software presents some challenges. Software often requires a specific technology stack to operate. This can include software, operating systems and hardware dependencies. One past approach to preserve computational capabilities is to maintain ancient hardware long past its typical viability. On an archive horizon of 100 years, this is not feasible. Another approach to preserve computational capabilities is to archive source code. While this can preserve details of the implementation and algorithms, it may not be possible to reproduce the technology stack needed to compile and run the resulting applications. This future forward dilemma has a solution. Technology used to create clouds and process big data can also be used to archive and preserve computational capabilities. We explore how basic hardware, virtual machines, containers and appropriate metadata can be used to preserve computational capabilities and to archive functional software systems. In conjunction with data archives, this provides scientist with both the data and capability to reproduce the processing and analysis used to generate past scientific results.

As of January 2015, the new maximum limit of fuel sulfur content for ships sailing within emission control areas has been reduced to 0.1%. A critical decision for ship owners in advance of the new limits was the selection of an abatement method that complies with the regulations. Two main options...... exist: investing in scrubber systems that remove sulfur dioxide emissions from the exhaust and switching to low-sulfur fuel when sailing in regulated waters. The first option would involve significant capital costs, while the latter would lead to operating cost increases because of the higher price...

The new version v4.1 of the Emission Database for Global Atmospheric Research (EDGAR) compiled by JRC and PBL provides independent estimates of the global anthropogenic emissions and emission trends of precursors of tropospheric ozone (CO, NMVOC, NOx) and acidifying substances (NOx, NH3, SO2) for the period 1970-2005. All emissions are detailed at country level consistently using the same technology-based methodology, combining activity data (international statistics) from publicly available sources and to the extent possible emission factors as recommended by the EMEP/EEA air pollutant emission inventory guidebook. By using high resolution global grid maps per source category of area sources and point sources, we also compiled datasets with annual emissions on a 0.1x0.1 degree grid, as input for atmospheric models. We provide full and up-to-date inventories per country, also for developing countries. Moreover, the time series back in time to 1970 provides for the trends in official national inventories a historic perspective. As part of our objective to contribute to more reliable inventories by providing a reference emissions database for emission scenarios, inventory comparisons and for atmospheric modellers, we strive to transparently document all data sources used and assumptions made where data was missing, in particular for assumptions made on the shares of technologies where relevant. Technology mixes per country or region were taken from other data sources (such as the Platts database) or estimated using other sources or countries as proxy. The evolution in the adoption of technologies world-wide over the 35 years covered by EDGAR v4.1 will be illustrated for the power industry and the road transport sectors, in particular for Europe and the US. Similarly the regional and global impacts of implemented control measures and end-of pipe abatements will be illustrated by the examples of - NOx and SO2 end-of pipe abatements being implemented since the late

Xu, Lang; Wang, Chuanxu; Li, Hui

2017-06-08

We focus on the impacts of technological spillovers and environmental awareness in a two-echelon supply chain with one-single supplier and one-single manufacturer to reduce carbon emission. In this supply chain, carbon abatement investment becomes one of key factors of cutting costs and improving profits, which is reducing production costs in the components and products-the investment from players in supply chain. On the basis of optimality theory, the centralized and decentralized models are respectively established to investigate the optimal decisions and profits. Further, setting the players' profits of the decentralized scenario as the disagreement points, we propose a bargaining-coordination contract through revenue-cost sharing to enhance the performance. Finally, by theoretical comparison and numerical analysis, the results show that: (i) The optimal profits of players and supply chain improve as technological spillovers and environmental awareness increase, and the profits of them in the bargaining-coordination contract are higher than that in the decentralized scenario; (ii) Technological spillovers between the players amplify the impact of "free-ride" behavior, in which the supplier always incentives the manufacturer to improve carbon emission intensity, but the cooperation will achieves and the profits will improve only when technological spillovers and environmental awareness are great; (iii) The contract can effectively achieve coordinated supply chain, and improve carbon abatement investment.

The European Commission's Roadmap for a competitive and low carbon economy in 2050 indicates that greenhouse gas emissions (GHG) in all sectors should be significantly reduced to meet the European Union (EU) objective of 80 to 95% greenhouse gas emission reductions by 2050 compared to 1990 levels. The European Commission indicated in the Roadmap that the EU's industrial sectors should reduce emissions by 83 to 87% domestically by 2050 compared to 1990 levels. The objective of this study is to explore breakthrough abatement technologies in three processes in the European chemical industry that can considerably contribute to achieving the required greenhouse gas emission reductions. In this context we have assessed the processes for the production of: (1) Ammonia; (2) Olefins; (3) Aromatics (BTX). For all three processes possible breakthrough abatement technologies were found, allowing for reductions in GHG emissions varying between 50 and 100% compared to the conventional processes. Our finding regarding the chemical industry and our earlier findings regarding options in the steel, cement and pulp and paper industries show that promising breakthrough abatement technologies are available for European energy-intensive industries to contribute to a low-carbon economy. However, large scale deployment requires an integrated EU industry and energy policy allowing for a resource efficient and sustainable use of available biomass, CCS storage capacity and renewable energy capacity.

Current decisions on greenhouse gas emissions may have effects on human well being for centuries. This project has aimed to extend the economic models designed for analyzing this particular issue. A closely related topic follows from the fact that emitting CO{sub 2} can be interpreted as a utilization of a free access resource, i.e., when countries gain from utilizing cheap fossil fuels (relative to noncarbon energy sources), the possible loss any country suffers from climate change is only a negligible fraction of the total loss of all countries. Thus, from a global point of view, the incentives for an individual country to abate emissions is low. Economic understanding of these problems calls for dynamic game-theoretical models

Highlights: ► A CFD model is developed for a UV-LED based photocatalytic deodorization reactor. ► Radiation field model and Langmuir–Hinshelwood kinetics are integrated in the model. ► The model can predict the pollutant concentration profile and the reactor performance. ► LED distance is predicted to be a critical parameter in photocatalytic reactor design. - Abstract: This paper presents a model study of a UV light-emitting-diode (UV-LED) based photocatalytic odor abatement process. It integrated computational fluid dynamics (CFD) modeling of the gas flow in the reactor with LED-array radiation field calculation and Langmuir–Hinshelwood reaction kinetics. It was applied to simulate the photocatalytic degradation of dimethyl sulfide (DMS) in a UV-LED reactor based on experimentally determined chemical kinetic parameters. A non-linear power law relating reaction rate to irradiation intensity was adopted. The model could predict the steady state DMS concentration profiles by calculating the advection, diffusion and Langmuir–Hinshelwood reaction kinetics. By affecting the radiation intensity and uniformity, the position of the LED array relative to the catalyst appeared to be a critical parameter determining DMS removal efficiency. Too small distances might yield low quantum efficiency and consequently poor abatement performance. This study provided an example of LED-based photocatalytic process modeling and gave insights into the optimization of light source design for photocatalytic applications.

Taxes, permits, and the diffusion of a new technology

International Nuclear Information System (INIS)

Coria, Jessica

2009-01-01

This study looks at the effects of the choice between taxes and permits on the pattern of adoption of a new (pollution) emissions abatement technology. It uses a dynamic setting, where the regulator observes the arrival and initial use of the technology and determines the optimal ex post amount of emissions before firms start to adopt the technology. In the model here, the adoption benefits and costs depend on the number of firms that are already using the technology. Thus, each firm decides the optimal date to adopt the technology, considering its benefits and costs, as well as the advantage they will gain over their rivals, producing a sequence of adoption that is ''diffused'' into the industry over time. With this framework, the study shows that when the output demand is elastic, auctioned permits induce an earlier diffusion than taxes. (author)

Quantification of environmental impacts of various energy technologies. Final report

Energy Technology Data Exchange (ETDEWEB)

Selfors, A [ed.

1994-10-01

This report discusses problems related to economic assessment of the environmental impacts and abatement measures in connection with energy projects. Attention is called to the necessity of assessing environmental impacts both in the form of reduced economic welfare and in the form of costs of abatement measures to reduce the impact. In recent years, several methods for valuing environmental impacts have been developed, but the project shows that few empirical studies have been carried out. The final report indicates that some important factors are very difficult to evaluate. In addition environmental impacts of energy development in Norway vary considerably from project to project. This makes it difficult to obtain a good basis for comparing environmental impacts caused by different technologies, for instance hydroelectric power versus gas power or wind versus hydroelectric power. It might be feasible however to carry out more detailed economic assessments of environmental impacts of specific projects. 33 refs., 1 fig., 4 tabs.

Demolition Range Noise Abatement Technique Demonstration and Evaluation for the McAlester Army Ammunition Plant; TOPICAL

2001-01-01

Public concern regarding the effects of noise generated by the detonation of excess and obsolete explosive munitions at U.S. Army demolition ranges is a continuing issue for the Army's demilitarization and disposal groups. Recent concerns of citizens living near the McAlester Army Ammunition Plant (MCAAP) in Oklahoma have lead the U.S. Army Defense Ammunition Center (DAC) to conduct a demonstration and evaluation of noise abatement techniques that could be applied to the MCAAP demolition range. With the support of the DAC, MCAAP, and Sandia National Laboratories (SNL), three types of noise abatement techniques were applied: aqueous foams, overburden (using combinations of sand beds and dirt coverings), and rubber or steel blast mats. Eight test configurations were studied and twenty-four experiments were conducted on the MCAAP demolition range in July of 2000. Instrumentation and data acquisition systems were fielded for the collection of near-field blast pressures, far-field acoustic pressures, plant boundary seismic signals, and demolition range meteorological conditions. The resulting data has been analyzed and reported, and a ranking of each technique's effects has been provided to the DAC

Baseline Assessment and Prioritization Framework for IVHM Integrity Assurance Enabling Capabilities

Fundamental to vehicle health management is the deployment of systems incorporating advanced technologies for predicting and detecting anomalous conditions in highly complex and integrated environments. Integrated structural integrity health monitoring, statistical algorithms for detection, estimation, prediction, and fusion, and diagnosis supporting adaptive control are examples of advanced technologies that present considerable verification and validation challenges. These systems necessitate interactions between physical and software-based systems that are highly networked with sensing and actuation subsystems, and incorporate technologies that are, in many respects, different from those employed in civil aviation today. A formidable barrier to deploying these advanced technologies in civil aviation is the lack of enabling verification and validation tools, methods, and technologies. The development of new verification and validation capabilities will not only enable the fielding of advanced vehicle health management systems, but will also provide new assurance capabilities for verification and validation of current generation aviation software which has been implicated in anomalous in-flight behavior. This paper describes the research focused on enabling capabilities for verification and validation underway within NASA s Integrated Vehicle Health Management project, discusses the state of the art of these capabilities, and includes a framework for prioritizing activities.

Science, information, technology, and the changing character of public policy in non-point source pollution

Science.gov (United States)

King, John L.; Corwin, Dennis L.

Information technologies are already delivering important new capabilities for scientists working on non-point source (NPS) pollution in the vadose zone, and more are expected. This paper focuses on the special contributions of modeling and network communications for enhancing the effectiveness of scientists in the realm of policy debates regarding NPS pollution mitigation and abatement. The discussion examines a fundamental shift from a strict regulatory strategy of pollution control characterized by a bureaucratic/technical alliance during the period through the 1970's and early 1980's, to a more recently evolving paradigm of pluralistic environmental management. The role of science and scientists in this shift is explored, with special attention to the challenges facing scientists working in NPS pollution in the vadose zone. These scientists labor under a special handicap in the evolving model because their scientific tools are often times incapable of linking NPS pollution with individuals responsible for causing it. Information can facilitate the effectiveness of these scientists in policy debates, but not under the usual assumptions in which scientific truth prevails. Instead, information technology's key role is in helping scientists shape the evolving discussion of trade-offs and in bringing citizens and policymakers closer to the routine work of scientists.

Analysis of the economic impact of different Chinese climate policy options based on a CGE model incorporating endogenous technological change

2009-01-01

Abatement cost is the main concern for climate change mitigation and the key factor for mitigation cost is technological change. This study established an integrated economic, energy, environmental, dynamic, computable general equilibrium (CGE) model representing endogenous technological change for China's climate change policy analysis. This study analyzed and compared the economic impact of different approaches to mitigation commitments as well as the potential role of technological change in the formulation of mitigation targets and commitments, taking into account China's climate policy-making needs based on the current international climate negotiation process. The results show that, absolute emission limits similar to the Kyoto Protocol will seriously impede the future economic development of China, while the impact of an 80% reduction in carbon intensity, forecast for 2050 based on the 2005 level, is relatively small. Technological change can promote economic growth, improve energy efficiency and reduce carbon intensity per unit of output through the substitution of production factors. Consequently it can reduce marginal abatement cost and related GDP loss by mitigation. At the same time it can increase mitigation potentials and extend the emission reduction amount, showing that consideration of the impact of technological change when deciding the emission reduction targets is necessary.

2015-01-01

Education and training (E&T) have always been key factor to the sustainability of the nuclear industry. With regard to E&T it is still the challenge to raise the interest of qualified young people of studies and professions related to nuclear technologies. CORONA Project is established to provide a special purpose structure for training and for gathering the existing and generating new knowledge in the VVER area as well as to contribute to transnational mobility and lifelong learning amongst VVER operating countries. CORONA Project consists of two parts: CORONA I (2011–2014) “Establishment of a regional centre of competence for VVER technology and Nuclear Applications”, co-financed by the EC Framework Programme 7 and CORONA II “Enhancement of training capabilities in VVER technology through establishment of VVER training academy”, co-financed by the EURATOM 2014-2015 Working programme of HORIZON 2020. The project is focused on development of training schemes for VVER nuclear professionals, subcontractors, students and for non-nuclear specialists working in support of nuclear applications as civil engineers, physical protection employees, government employees, secondary school teachers, journalists. Safety culture and soft skills training are incorporated as an integral part of all training schemes because they require continuous consideration. It is vital for the acceptance of nuclear energy by the public and for the safe performance of the nuclear installations. CORONA II project is to proceed with the development of state-of-the-art virtual training centre — CORONA Academy. This objective will be realised through networking between universities, research organizations, regulatory bodies, industry and any other organizations involved in the application of nuclear science, ionising radiation and nuclear safety. It will bring together the most experienced trainers and will allow trainees from different locations to access the needed knowledge on demand

This article considers the licensing strategies of eco-technology when an innovator provides pollution abatement goods to oligopolistic polluting firms that produce consumption goods and emit environmental pollutants. In the presence of emission tax, two types of licensing contracts, royalty and fixed-fee, are examined to analyze market equilibrium and to compare their welfare consequences. We show that an eco-innovator provides a non-exclusive license under a royalty contract while it might ...

Investments by NASA to build planetary protection capability

Buxbaum, Karen; Conley, Catharine; Lin, Ying; Hayati, Samad

NASA continues to invest in capabilities that will enable or enhance planetary protection planning and implementation for future missions. These investments are critical to the Mars Exploration Program and will be increasingly important as missions are planned for exploration of the outer planets and their icy moons. Since the last COSPAR Congress, there has been an opportunity to respond to the advice of NRC-PREVCOM and the analysis of the MEPAG Special Regions Science Analysis Group. This stimulated research into such things as expanded bioburden reduction options, modern molecular assays and genetic inventory capability, and approaches to understand or avoid recontamination of spacecraft parts and samples. Within NASA, a portfolio of PP research efforts has been supported through the NASA Office of Planetary Protection, the Mars Technology Program, and the Mars Program Office. The investment strategy focuses on technology investments designed to enable future missions and reduce their costs.

Household Solar Photovoltaics: Supplier of Marginal Abatement, or Primary Source of Low-Emission Power?

Directory of Open Access Journals (Sweden)

Graham Palmer

2013-03-01

Full Text Available With declining system costs and assuming a short energy payback period, photovoltaics (PV should, at face value, be able to make a meaningful contribution to reducing the emission intensity of Australia’s electricity system. However, solar is an intermittent power source and households remain completely dependent on a “less than green” electricity grid for reliable electricity. Further, much of the energy impact of PV occurs outside of the conventional boundaries of PV life-cycle analyses (LCA. This paper examines these competing observations and explores the broader impacts of a high penetration of household PV using Melbourne, Victoria as a reference. It concludes that in a grid dominated by unsequestered coal and gas, PV provides a legitimate source of emission abatement at high, but declining costs, with the potential for network and peak demand support. It may be technically possible to integrate a high penetration of PV, but the economic and energy cost of accommodating high-penetration PV erodes much of the benefits. Future developments in PV, storage, and integration technologies may allow PV to take on a greater long term role, but in the time horizon usually discussed in climate policy, a large-scale expansion of household PV may hinder rather than assist deep cuts to the emission intensity of Australia’s electricity system.

Legitimacy, capability, effectiveness and the future of the NPT

International Nuclear Information System (INIS)

Keeley, J.F.

1987-01-01

This chapter looks at the relationship between legitimacy and capability in conceptually and politically contestable regions. This issue was highlighted by India's nuclear test of May 1974 and the Osiraq raid of 1981. These illustrated the general problem of the threat to the coherence and legitimacy of the non-proliferation regime. This threat arose from the spread of nuclear technological capabilities. Two developments in the non-proliferation regime that have helped produce the more specific problems of that regime are discussed. These are the spread of nuclear technological capabilities and the development of complex co-operation networks. The prospects for the modification of the NPT in response to these challenges are considered finally. (U.K.)

Acid dispersion abatement: the use of flue gas desulphurisation in the UK

Energy Technology Data Exchange (ETDEWEB)

Longhurst, J.W.S.; Health, B.A.; Gibber, D.C. [Manchester Metropolitan University, Manchester (United Kingdom). Atmospheric Research and Information Centre, Dept. of Environmental and Geographical Sciences

1995-12-31

This paper reviews and evaluates the development of the UK flue gas desulphurisation (FGD) programme. This programme on establishment in 1986 represented a planned and coherent approach to acid deposition abatement which would progressively reduce emissions whilst maintaining the UK`s coal fired power generation capacity. It was anticipated that at least 12000 MW of electricity generating plant would be retrofitted with FGD. The programme has effectively been abandoned in favour of market based approach to emission control which sets the targets to be achieved but not the means. As a consequence the retrofitted capacity in 1995 is just 6000 MW. 17 refs., 1 tab.

"This is not your father's low-light sensor," Steve Miller, senior research scientist and deputy director of the Cooperative Institute for Research in the Atmosphere at Colorado State University, Fort Collins, said at a 5 December news briefing at the AGU Fall Meeting. He and others at the briefing were showing off the nighttime sensing capability of the day/night band of the Visible Infrared Imaging Radiometer Suite (VIIRS) of instruments onboard the Suomi National Polar-orbiting Partnership (NPP) Earth-observing research satellite, a joint NASA and National Oceanic and Atmospheric Administration (NOAA) satellite that was launched on 28 October 2011. Noting that low-light satellite technology has been available for about 40 years, Miller said that the VIIRS day/night band "is truly a paradigm shift in the technology and capability."

Integrated System Health Management (ISHM): Systematic Capability Implementation

Science.gov (United States)

Figueroa, Fernando; Holland, Randy; Schmalzwel, John; Duncavage, Dan

2006-01-01

This paper provides a credible approach for implementation of ISHM capability in any system. The requirements and processes to implement ISHM capability are unique in that a credible capability is initially implemented at a low level, and it evolves to achieve higher levels by incremental augmentation. In contrast, typical capabilities, such as thrust of an engine, are implemented once at full Functional Capability Level (FCL), which is not designed to change during the life of the product. The approach will describe core ingredients (e.g. technologies, architectures, etc.) and when and how ISHM capabilities may be implemented. A specific architecture/taxonomy/ontology will be described, as well as a prototype software environment that supports development of ISHM capability. This paper will address implementation of system-wide ISHM as a core capability, and ISHM for specific subsystems as expansions and evolution, but always focusing on achieving an integrated capability.

Dynamic capabilities and innovation management: a conceptual approach

Full Text Available Organizational capabilities are those behavioral routines oriented to develop a specific task (NELSON; WINTER, 1982. These capabilities define what the company knows to do and how must to do it. Nevertheless, the repetitive character of these capabilities could be producing stopped processes (METCALFE, 1995 which both limit the generation of new capabilities and diminishing the dynamism in the production, reproduction and reconfiguration of new capabilities (TEECE; PISANO, 1997. This article compares and analyzes different theoretical-conceptual perspectives for generation and reconfiguration of technological capabilities within an organization. Additionally this article suggests that dynamic capabilities to make feasible innovation processes within an organization. The general concept of dynamic capacities will be used like driver of changes to produce and reconfigurate capabilities in the organization. The glance of the dynamic capabilities allows understanding the complexity of the creation, development and use of capabilities. This understanding could constitute material fundamental to manage learning processes and organizational change oriented to innovation.

Emerging catalytic technologies related to the denoxing of waste gases from thermal power stations

International Nuclear Information System (INIS)

Busca, G.

2002-01-01

The emerging catalytic technologies related to the DeNOxing of waste gases from thermal power stations are briefly discussed. In the case of the Selective Catalytic Reduction of NO x with hydrocarbons new zeolite-based or metal oxide catalytic systems are under development, whose stability and performances approach more and more those needed for a commercial process. The processes for the low temperature Selective Catalytic Reduction of NO x with ammonia are apparently promising allowing a possible application in a tail-end process configuration, at least after a total abatement of SO x . The processes of combined abatement of NO x and dioxins are already applied industrially. Also the Selective Oxidation of ammonia slip to nitrogen is already proposed as commercial process. In both last cases, however, few information is available in the open literature [it

Carniato, Fabio; Bisio, Chiara; Psaro, Rinaldo; Marchese, Leonardo; Guidotti, Matteo

2014-09-15

A Nb(V)-containing saponite clay was designed to selectively transform toxic organosulfur chemical warfare agents (CWAs) under extremely mild conditions into nontoxic products with reduced environmental impact. Thanks to the insertion of Nb(V) sites within the saponite framework, a bifunctional catalyst with strong oxidizing and acid properties was obtained. Remarkable activity and high selectivity were observed for the oxidative abatement of (2-chloroethyl)ethyl sulfide (CEES), a simulant of sulfur mustard, at room temperature with aqueous hydrogen peroxide. This performance was significantly better compared to a conventional commercial decontamination powder. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

2007-01-01

The use of nuclear technology has been widely employed and will continue to expand in use in Nigeria particularly in the health, industrial, mining, water resources, agriculture, manufacturing, education and research sectors. Incidents and emergencies cannot therefore be ruled out. Effective national response capabilities are essential to minimize the impacts from nuclear and radiological emergencies, and to build public trust in the safety and security of nuclear technology. The often discussed Nigeria's Nuclear Power Plant (NPP) project cannot occur without enhanced national capabilities to respond to an incidence or emergency. Moreover, increased concern over the use of nuclear or radioactive materials malevolent acts increases the need to broaden response capabilities. This paper examines Nigeria's status on capabilities for response to a nuclear and radiological emergency vis-a-vis international requirements for effective response capabilities

Abatement cost of SF6 emissions from medium voltage switchgear. Validation of recent studies for the European Commission

Energy Technology Data Exchange (ETDEWEB)

Benner, J.; Van Lieshout, M.; Croezen, H.

2012-05-15

Sulphur hexafluoride (SF6) is a gas with applications including use as an insulator and switching medium in medium voltage (MV) switchgear. While having certain unique properties, it is also a greenhouse gas, with a 22,800 times greater impact than CO2 and an atmospheric lifetime of over 3,000 years. Although the use of SF6 in MV switchgear can be avoided, according to recent studies for the European Commission, the abatement costs are high. This study validates the calculated cost levels as well as the general feasibility of determining a fixed cost figure for this purpose. This analysis yields a result which differs from the earlier studies, particularly with respect to the cost aspect, but also in other areas. CE Delft concludes that for the majority of applications cost-effective SF6-free options are available, leading to abatement costs for the use of SF6 in MV switchgear that range from - 40 to 0 euro/tCO2 eq., for all types of switchgear, with voltage levels below 25 kV and situated on relatively dry locations.

Distributed collaboration is an emerging technology for the 21st century that will significantly change how business is conducted in the defense and commercial sectors. Collaboration involves two or more geographically dispersed entities working together to create a "product" by sharing and exchanging data, information, and knowledge. A product is defined broadly to include, for example, writing a report, creating software, designing hardware, or implementing robust systems engineering and capability planning processes in an organization. Collaborative environments provide the framework and integrate models, simulations, domain specific tools, and virtual test beds to facilitate collaboration between the multiple disciplines needed in the enterprise. The Air Force Research Laboratory (AFRL) is conducting a leading edge program in developing distributed collaborative technologies targeted to the Air Force's implementation of systems engineering for a simulation-aided acquisition and capability-based planning. The research is focusing on the open systems agent-based framework, product and process modeling, structural architecture, and the integration technologies - the glue to integrate the software components. In past four years, two live assessment events have been conducted to demonstrate the technology in support of research for the Air Force Agile Acquisition initiatives. The AFRL Collaborative Environment concept will foster a major cultural change in how the acquisition, training, and operational communities conduct business.

Following the 2010 Nuclear Security Summit, Canada expanded its existing capability for nuclear forensics by establishing a national nuclear forensics laboratory network, which would include a capability to perform forensic analysis on nuclear and other radioactive material, as well as on traditional evidence contaminated with radioactive material. At the same time, the need for a national nuclear forensics library of signatures of nuclear and radioactive materials under Canadian regulatory control was recognized. The Canadian Safety and Security Program, administered by Defence Research and Development Canada's Centre for Security Science (DRDC CSS), funds science and technology initiatives to enhance Canada's preparedness for prevention of and response to potential threats. DRDC CSS, with assistance from Canadian Nuclear Laboratories, formerly Atomic Energy of Canada Limited, is leading the Canadian National Nuclear Forensics Capability Project to develop a coordinated, comprehensive, and timely national nuclear forensics capability.

2014-08-01

In the present study, the treatability of indigo dyeing effluents by the electrocoagulation (EC) process using stainless steel electrodes was experimentally investigated. The samples used were concentrated with main pollutant parameters of chemical oxygen demand (COD) (1000-1100 mg/L), reduced sulphur species (over 2000 mg SO2-(3)/L), and colour (0.12-0.13 1/cm). The study focused on the effect of main operation parameters on the EC process performance in terms of abatement of reduced sulphur compounds as well as decolourization and organic matter reduction. Results indicated that the performance of EC proved to be high providing total oxidation of the reduced sulphur compounds, almost complete decolourization, and COD removal up to 90%. Increasing applied current density from 22.5 to 45 mA/cm2 appreciably improved abatement of the reduced sulphur compounds for Sample I, but a further increase in the applied current density to 67.5 mA/cm2 did not accelerate the conversion rate to sulphate. The process performance was adversely affected by increasing initial concentration of the reduced sulphur compounds. Decolourization and organic matter removal efficiency enhanced with increasing applied current density. The main removal mechanism of the reduced sulphur compounds by EC was explained as conversion to sulphate via oxidation. Conversion rate to sulphate fitted pseudo-first-order kinetics very well.

Greenhouse gas mitigation potential of biomass energy technologies in Vietnam using the long range energy alternative planning system model

International Nuclear Information System (INIS)

Kumar, Amit; Bhattacharya, S.C.; Pham, H.L.

2003-01-01

The greenhouse gas (GHG) mitigation potentials of number of selected Biomass Energy Technologies (BETs) have been assessed in Vietnam. These include Biomass Integrated Gasification Combined Cycle (BIGCC) based on wood and bagasse, direct combustion plants based on wood, co-firing power plants and Stirling engine based on wood and cooking stoves. Using the Long-range Energy Alternative Planning (LEAP) model, different scenarios were considered, namely the base case with no mitigation options, replacement of kerosene and liquefied petroleum gas (LPG) by biogas stove, substitution of gasoline by ethanol in transport sector, replacement of coal by wood as fuel in industrial boilers, electricity generation with biomass energy technologies and an integrated scenario including all the options together. Substitution of coal stoves by biogas stove has positive abatement cost, as the cost of wood in Vietnam is higher than coal. Replacement of kerosene and LPG cookstoves by biomass stove also has a positive abatement cost. Replacement of gasoline by ethanol can be realized after a few years, as at present the cost of ethanol is more than the cost of gasoline. The replacement of coal by biomass in industrial boiler is also not an attractive option as wood is more expensive than coal in Vietnam. The substitution of fossil fuel fired plants by packages of BETs has a negative abatement cost. This option, if implemented, would result in mitigation of 10.83 million tonnes (Mt) of CO 2 in 2010

Increasing importance has been attached to the value of information technology (IT) infrastructure in today's organizations. The development of efficacious IT infrastructure capability enhances business performance and brings sustainable competitive advantage. This study analyzed the IT infrastructure capability in a holistic way and then presented a concept model of IT capability. IT infrastructure capability was categorized into sharing capability, service capability, and flexibility. This study then empirically tested the model using a set of survey data collected from 145 firms. Three factors emerge from the factor analysis as IT flexibility, IT service capability, and IT sharing capability, which agree with those in the conceptual model built in this study.

Policy interactions, risk and price formation in carbon markets

International Nuclear Information System (INIS)

Blyth, William; Bunn, Derek; Kettunen, Janne; Wilson, Tom

2009-01-01

Carbon pricing is an important mechanism for providing companies with incentives to invest in carbon abatement. Price formation in carbon markets involves a complex interplay between policy targets, dynamic technology costs, and market rules. Carbon pricing may under-deliver investment due to R and D externalities, requiring additional policies which themselves affect market prices. Also, abatement costs depend on the extent of technology deployment due to learning-by-doing. This paper introduces an analytical framework based on marginal abatement cost (MAC) curves with the aim of providing an intuitive understanding of the key dynamics and risk factors in carbon markets. The framework extends the usual static MAC representation of the market to incorporate policy interactions and some technology cost dynamics. The analysis indicates that supporting large-scale deployment of mature abatement technologies suppresses the marginal cost of abatement, sometimes to zero, whilst increasing total abatement costs. However, support for early stage R and D may reduce both total abatement cost and carbon price risk. An important aspect of the analysis is in elevating risk management considerations into energy policy formation, as the results of the stochastic modelling indicate wide distributions for the emergence of carbon prices and public costs around the policy expectations.

2014-01-01

This paper examines how much carbon emissions from the electricity industry would decrease in response to a carbon price. We show how both carbon prices and cheap natural gas reduce, in a nearly identical manner, the historic cost advantage of coal-fired power plants. The shale revolution has resulted in unprecedented variation in natural gas prices that we use to estimate the short-run price elasticity of abatement. Our estimates imply that a price of $10 ($60) per ton of carbon dioxide woul...

Integrating rehabilitation services through wearable systems has the potential to accurately assess the type, intensity, duration, and quality of movement necessary for procuring key outcome measures. This review aims to explore wearable accelerometry-based technology (ABT) capable of assessing mobility-related functional activities intended for rehabilitation purposes in community settings for neurological populations. In this review, we focus on the accuracy of ABT-based methods, types of outcome measures, and the implementation of ABT in non-clinical settings for rehabilitation purposes. Cochrane, PubMed, Web of Knowledge, EMBASE, and IEEE Xplore. The search strategy covered three main areas, namely wearable technology, rehabilitation, and setting. Potentially relevant studies were categorized as systems either evaluating methods or outcome parameters. Methodological qualities of studies were assessed by two customized checklists, depending on their categorization and rated independently by three blinded reviewers. Twelve studies involving ABT met the eligibility criteria, of which three studies were identified as having implemented ABT for rehabilitation purposes in non-clinical settings. From the twelve studies, seven studies achieved high methodological quality scores. These studies were not only capable of assessing the type, quantity, and quality measures of functional activities, but could also distinguish healthy from non-healthy subjects and/or address disease severity levels. While many studies support ABT's potential for telerehabilitation, few actually utilized it to assess mobility-related functional activities outside laboratory settings. To generate more appropriate outcome measures, there is a clear need to translate research findings and novel methods into practice.

Tsunami disaster risk management capabilities in Greece

Science.gov (United States)

Marios Karagiannis, Georgios; Synolakis, Costas

2015-04-01

Greece is vulnerable to tsunamis, due to the length of the coastline, its islands and its geographical proximity to the Hellenic Arc, an active subduction zone. Historically, about 10% of all world tsunamis occur in the Mediterranean region. Here we review existing tsunami disaster risk management capabilities in Greece. We analyze capabilities across the disaster management continuum, including prevention, preparedness, response and recovery. Specifically, we focus on issues like legal requirements, stakeholders, hazard mitigation practices, emergency operations plans, public awareness and education, community-based approaches and early-warning systems. Our research is based on a review of existing literature and official documentation, on previous projects, as well as on interviews with civil protection officials in Greece. In terms of tsunami disaster prevention and hazard mitigation, the lack of tsunami inundation maps, except for some areas in Crete, makes it quite difficult to get public support for hazard mitigation practices. Urban and spatial planning tools in Greece allow the planner to take into account hazards and establish buffer zones near hazard areas. However, the application of such ordinances at the local and regional levels is often difficult. Eminent domain is not supported by law and there are no regulatory provisions regarding tax abatement as a disaster prevention tool. Building codes require buildings and other structures to withstand lateral dynamic earthquake loads, but there are no provisions for resistance to impact loading from water born debris Public education about tsunamis has increased during the last half-decade but remains sporadic. In terms of disaster preparedness, Greece does have a National Tsunami Warning Center (NTWC) and is a Member of UNESCO's Tsunami Program for North-eastern Atlantic, the Mediterranean and connected seas (NEAM) region. Several exercises have been organized in the framework of the NEAM Tsunami Warning

'Capture ready' regulation of fossil fuel power plants - Betting the UK's carbon emissions on promises of future technology

International Nuclear Information System (INIS)

Markusson, Nils; Haszeldine, Stuart

2010-01-01

Climate change legislation requires emissions reductions, but the market shows interest in investing in new fossil fuelled power plants. The question is whether capture ready policy can reconcile these interests. The term 'capture ready' has been used a few years by the UK Government when granting licences for fossil fuelled power plants, but only recently has the meaning of the term been defined. The policy has been promoted as a step towards CCS and as an insurance against carbon lock-in. This paper draws on literature on technology lock-in and on regulation of technology undergoing development. Further, versions of the capture readiness concept proposed to date are compared. Capture readiness requirements beyond the minimum criterion of space on the site for capture operations are explored. This includes integration of capture and power plant, downstream operations, overall system integration and regulation of future retrofitting. Capture readiness comes with serious uncertainties and is no guarantee that new-built fossil plants will be abatable or abated in the future. As a regulatory strategy, it has been over-promised in the UK.

A review of current technologies used to control gaseous emissions produced by combustion processes is given. Fly ash and particulates are successfully removed (99,9%) by using electromagnetic filters and fabric filters. Desulfurization is achieved by adding limestone into the furnace or using scrubbers where gases are mixed with a water solution plus mentalizing agents. Denitrification is performed by three ways: better conditions of the burner, by injecting chemical products into the furnace and using catalysts.

ARCHITECT: The architecture-based technology evaluation and capability tradeoff method

Science.gov (United States)

Griendling, Kelly A.

The use of architectures for the design, development, and documentation of system-of-systems engineering has become a common practice in recent years. This practice became mandatory in the defense industry in 2004 when the Department of Defense Architecture Framework (DoDAF) Promulgation Memo mandated that all Department of Defense (DoD) architectures must be DoDAF compliant. Despite this mandate, there has been significant confusion and a lack of consistency in the creation and the use of the architecture products. Products are typically created as static documents used for communication and documentation purposes that are difficult to change and do not support engineering design activities and acquisition decision making. At the same time, acquisition guidance has been recently reformed to move from the bottom-up approach of the Requirements Generation System (RGS) to the top-down approach mandated by the Joint Capabilities Integration and Devel- opment System (JCIDS), which requires the use of DoDAF to support acquisition. Defense agencies have had difficulty adjusting to this new policy, and are struggling to determine how to meet new acquisition requirements. This research has developed the Architecture-based Technology Evaluation and Capability Tradeoff (ARCHITECT) Methodology to respond to these challenges and address concerns raised about the defense acquisition process, particularly the time required to implement parts of the process, the need to evaluate solutions across capability and mission areas, and the need to use a rigorous, traceable, repeatable method that utilizes modeling and simulation to better substantiate early-phase acquisition decisions. The objective is to create a capability-based systems engineering methodology for the early phases of design and acquisition (specifically Pre-Milestone A activities) which improves agility in defense acquisition by (1) streamlining the development of key elements of JCIDS and DoDAF, (2) moving the

Greenhouse-Gas Emissions and Abatement Costs of Nuclear, Fossil and Alternative Energy Options from a Life-Circle Perspective. Working paper

2007-03-01

As the issue of nuclear risks in its various forms - from radiation released during uranium mining to severe reactor accidents, and leakage from fuel reprocessing and repositories for spent fuel - is beyond the scope of this paper, we concentrate the following analysis on the more recent issues for which a scientifically reasonable range of data is available. In that respect, two arguments favouring nuclear electricity can be identified: It is allegedly free of CO2, and it is allegedly low cost. In this paper, we address both, presenting results of life-cycle cost and emission analyses of energy systems with respect to current technologies. We discuss the results with respect to other findings in the literature, and also indicate the cost-effectiveness of CO2 abatement in the electricity sector. The scientific work from which this paper draws was sponsored by a variety of sources, including the German Federal Ministry for Environment, Nature Protection, and Nuclear Safety (BMU), German Federal Ministry for Research and Education (BMBF), The Federal Environment Agency of Germany (UBA).

Rootzen, Johan

2012-11-01

In February 2011, the European Council reconfirmed the goal of reducing EU greenhouse gas emissions by at least 80 % by 2050, as compared to the levels in 1990. The power and industrial sectors currently account for almost half of the total GHG emissions in the EU. The overall objective of the work presented in this thesis is to provide a technology-based perspective on the feasibility of significant reductions in CO{sub 2} emissions in the EU power and industrial sectors, with the emphasis on expected turnover in the capital stock of the existing infrastructure. Three sectors of industry are included: petroleum refining; iron and steel production; and cement manufacturing. The analysis is based on a thorough description and characterization of the current industry infrastructure and of the key mitigation technologies and measures in each sector. The analysis comprises investigations of how specific factors, such as the age structure of the capital stock, technology and fuel mix, and spatial distribution of the plant stock, contribute to facilitating or hindering the shift towards less-emission-intensive production processes. The results presented here are the synthesis of the results described in the following three papers: Paper I investigates the potential for CCS in industrial applications in the EU by considering branch- and plant-specific conditions; Paper II assesses strategies for CO{sub 2} abatement in the European petroleum refining industry; and Paper III explores in a scenario analysis the limits for CO{sub 2} emission abatement within current production processes in the power and industrial sectors. Together, the three papers provide a comprehensive assessment of the roles of technologies and measures that are commercially available today, as well as those of emerging technologies that are still in their early phases of development. The results presented in Paper III show that the EU goal for emissions reductions in the sectors covered by the EU ETS, i

Through evolution, nature came up with many effective solutions to its challenges and continually improving them. By mimicking, coping and being inspired, humans have been using Nature's solutions to address their own challenges. In recent years, the implementation of nature's capabilities has intensified with our growing understanding of the various biological and nastic mechanisms and processes. Successes include even the making of humanlike robots that perform such lifelike tasks as walking, talking, making eye-contact, interpreting speech and facial expressions, as well as many other humanlike functions. Generally, once humans are able to implement a function then, thru rapid advances in technology, capabilities are developed that can significantly exceed the original source of inspiration in Nature. Examples include flight where there is no species that can fly as high, carry so much mass, has so large dimensions and fly so fast, and operate at as such extreme conditions as our aircraft and other aerospace systems. However, using the capabilities of today's technology, there are many challenges that are not feasible to address in mimicking characteristics of species and plants. In this manuscript, state-of-the-art of biomimetic capabilities, potentials and challenges are reviewed.

UNEP greenhouse gas abatement costing studies

1992-04-01

The project initiated by the United Nations Environment Programme aims to clarify some economic issues involved in greenhouse gas limitation by carrying out comparative studies of various nations. The programme should contribute to the establishment of a consistent methodological framework for making cost assessments of greenhouse gas abatement and help to support countries in the process of establishing national and international agreements on actions to combat climate change. The publication gives a survey of Danish energy demand and supply, emissions and current energy policy issues and reviews existing studies of carbon dioxide reductions. This includes the overall national environmental policy and the plan of action for the transport sector. Conclusions are that there seems to be a long-term potential for significant reduction of CO 2 emission by 10-15% by 2010 with no additional costs, a 50% reduction will cost DKK 25-50 per kg reduced CO 2 . The most promising options include increased use of cogeneration of heat and electricity, and electricity conservation in households, services and in industry. Economic growth is forecast as ca. 2.7% and energy prices for oil products should increase by ca. 4.8%. A 40% reduction of CO 2 emission in the year 2005 would increase costs by 1-2%, and a reduction of two thirds of present emission should be possible at no additional cost compared to the reference cases. There is general agreement that a reduction of carbon dioxide emission of 15-30% by 2005-10 should involve no additional costs to society. (AB) (11 refs.)

The efficiency of ozone-based processes under various conditions was studied for the treatment of a surface water (Lake Zürich water, Switzerland) spiked with 19 micropollutants (pharmaceuticals, pesticides, industrial chemical, X-ray contrast medium, sweetener) each at 1 μg L -1 . Two pilot-scale ozonation reactors (4-5 m 3  h -1 ), a 4-chamber reactor and a tubular reactor, were investigated by either conventional ozonation and/or the advanced oxidation process (AOP) O 3 /H 2 O 2 . The effects of selected operational parameters, such as ozone dose (0.5-3 mg L -1 ) and H 2 O 2 dose (O 3 :H 2 O 2  = 1:3-3:1 (mass ratio)), and selected water quality parameters, such as pH (6.5-8.5) and initial bromide concentration (15-200 μg L -1 ), on micropollutant abatement and bromate formation were investigated. Under the studied conditions, compounds with high second-order rate constants k O3 >10 4  M -1  s -1 for their reaction with ozone were well abated (>90%) even for the lowest ozone dose of 0.5 mg L -1 . Conversely, the abatement efficiency of sucralose, which only reacts with hydroxyl radicals (OH), varied between 19 and 90%. Generally, the abatement efficiency increased with higher ozone doses and higher pH and lower bromide concentrations. H 2 O 2 addition accelerated the ozone conversion to OH, which enables a faster abatement of ozone-resistant micropollutants. Interestingly, the abatement of micropollutants decreased with higher bromide concentrations during conventional ozonation due to competitive ozone-consuming reactions, except for lamotrigine, due to the suspected reaction of HOBr/OBr - with the primary amine moieties. In addition to the abatement of micropollutants, the evolution of the two main transformation products (TPs) of hydrochlorothiazide (HCTZ) and tramadol (TRA), chlorothiazide (CTZ) and tramadol N-oxide (TRA-NOX), respectively, was assessed by chemical analysis and kinetic modeling. Both selected TPs were quickly formed initially

The Core Capability and Technical Enhancement (CC&TE) Program, a part of the Verification, Validation, and Engineering Assessment Program, was implemented to enhance and augment the technical capabilities of the Idaho National Engineering and Environmental Laboratory (INEEL). The purpose for strengthening the technical capabilities of the INEEL is to provide the technical base to serve effectively as the Environmental Management Laboratory for the Office of Environmental Management (EM). An analysis of EM's science and technology needs as well as the technology investments currently being made by EM across the complex was used to formulate a portfolio of research activities designed to address EM's needs without overlapping work being done elsewhere. An additional purpose is to enhance and maintain the technical capabilities and research infrastructure at the INEEL. This is a progress report for fiscal year 1998 for the five CC&TE research investment areas: (a) transport aspects of selective mass transport agents, (b) chemistry of environmental surfaces, (c) materials dynamics, (d) characterization science, and (e) computational simulation of mechanical and chemical systems. In addition to the five purely technical research areas, this report deals with the science and technology foundations element of the CC&TE from the standpoint of program management and complex-wide issues. This report also provides details of ongoing and future work in all six areas.

Chance-constrained/stochastic linear programming model for acid rain abatement. I. Complete colinearity and noncolinearity

Energy Technology Data Exchange (ETDEWEB)

Ellis, J H; McBean, E A; Farquhar, G J

1985-01-01

A Linear Programming model is presented for development of acid rain abatement strategies in eastern North America. For a system comprised of 235 large controllable point sources and 83 uncontrolled area sources, it determines the least-cost method of reducing SO/sub 2/ emissions to satisfy maximum wet sulfur deposition limits at 20 sensitive receptor locations. In this paper, the purely deterministic model is extended to a probabilistic form by incorporating the effects of meteorologic variability on the long-range pollutant transport processes. These processes are represented by source-receptor-specific transfer coefficients. Experiments for quantifying the spatial variability of transfer coefficients showed their distributions to be approximately lognormal with logarithmic standard deviations consistently about unity. Three methods of incorporating second-moment random variable uncertainty into the deterministic LP framework are described: Two-Stage Programming Under Uncertainty, Chance-Constrained Programming and Stochastic Linear Programming. A composite CCP-SLP model is developed which embodies the two-dimensional characteristics of transfer coefficient uncertainty. Two probabilistic formulations are described involving complete colinearity and complete noncolinearity for the transfer coefficient covariance-correlation structure. The completely colinear and noncolinear formulations are considered extreme bounds in a meteorologic sense and yield abatement strategies of largely didactic value. Such strategies can be characterized as having excessive costs and undesirable deposition results in the completely colinear case and absence of a clearly defined system risk level (other than expected-value) in the noncolinear formulation.

Full Text Available In this short-review, the most common types of both pharmaceutical and personal care products (PPCP, a class of “emerging pollutants” are considered, as well as some of the most frequent methods for their removal that envisage the use of nanomaterials. The nanomaterials used in conservative methods (namely, reverse osmosis, nanofiltration and adsorption are basically nanoporous solids. Non-conservative methods, which include photocatalysis and Fenton reaction, are currently considered more promising than conservative ones, as the former allow the (at least partial degradation of the original molecules into more biodegradable by-products, which can be further abated by subsequent biological treatments, whereas the former are not efficient for the removal of small quantities of pollutants and have to be regenerated.

CO2 abatement potential of wood utilisation. Wood as an energy carrier

Wegener, G.; Fruehwald, A.

1994-01-01

Forests as ecosystems not only supply the raw material wood but also exert an influence on soils, water resources and many other ecological factors; provide animals with a habitat; and offer as humans a place for recreation. Recently, forests and wood have become of interest to human civilisation from yet another aspect: they constitute a carbon storage. This means that forestry and the forest industries can help moderate the increase of atmospheric CO 2 concentrations, which is essentially the result of energetic utilisation of fossil fuels and considered the decisive factor underlying the greenhouse effect. Besides constituting a carbon storage, forests hold an additional CO 2 abatement potential which can be realised by continuous utilisation of wood. (orig./EF) [de

This paper describes the innovative use information technology for assisting disaster planners with an easily-accessible method for writing and improving evidence-based emergency operations plans. This process is used to identify all key objectives of the emergency response according to capabilities of the institution, community or society. The approach then uses a standardized, objective-based format, along with a consensus-based method for drafting capability-based operational-level plans. This information is then integrated within a relational database to allow for ease of access and enhanced functionality to search, sort and filter and emergency operations plan according to user need and technological capacity. This integrated approach is offered as an effective option for integrating best practices of planning with the efficiency, scalability and flexibility of modern information and communication technology.

On September 11, 1986, a modified National Pollutant Discharge Elimination System permit was issued for the Oak Ridge Gaseous Diffusion Plant (ORGDP; now referred to as the Oak Ridge K-25 Site), a former uranium-enrichment production facility. As required in Part III of the permit, a Biological Monitoring and Abatement Program (BMAP) was developed for the biological monitoring of Mitchell Branch (K-1700 stream) and submitted for approval to the US EPA and the Tennessee Department of Environment and Conservation. The plan described biomonitoring activities that would be conducted over the duration of the permit. The objectives of the BMAP are to demonstrate that the effluent limitations established for the Oak Ridge K-25 Site protect and maintain the use of Mitchell Branch for growth and propagation of fish and other aquatic life, and to document the effects on stream biota resulting from operation of major new pollution abatement facilities. The BMAP consists of four tasks: ambient toxicity testing; bioaccumulation studies; biological indicator studies; and ecological surveys of stream communities, including benthic macroinvertebrates and fish. This document is the second in a series of reports presenting the results of the studies that were conducted over various periods of time between August 1987 and June 1990.

2017-06-01

Full Text Available Implementation of greenhouse gas (GHG abatement strategies often ends up as the responsibility of municipal action rather than national policies. Impacts of local GHG reduction measures were investigated in the EU FP7 funded project Urban Reduction of Greenhouse Gas Emissions in China and Europe (URGENCHE. Kuopio in Finland was one of the case study cities. The assessed reduction measures were (1 increased use of biomass in local heat and power cogeneration plant, (2 energy efficiency improvements of residences, (3 increased biofuel use in traffic, and (4 increased small scale combustion of wood for residential heating. Impact assessment compared the 2010 baseline with a 2020 BAU (business as usual scenario and a 2020 CO2 interventions scenario. Changes in emissions were assessed for CO2, particulate matter (PM2.5 and PM10, NOx, and SO2, and respective impacts were assessed for PM2.5 ambient concentrations and health effects. The assessed measures would reduce the local CO2 emissions in the Kuopio urban area by over 50% and local emissions of PM2.5 would clearly decrease. However, the annual average ambient PM2.5 concentration would decrease by just 4%. Thus, only marginal population level health benefits would be achieved with these assumed local CO2 abatement actions.

Materials Capability Review Los Alamos National Laboratory May 4-7, 2009

Taylor, Antoniette J [Los Alamos National Laboratory

2009-01-01

Los Alamos National Laboratory (LANL) uses external peer review to measure and continuously improve the quality of its science, technology and engineering (STE). LANL uses capability reviews to assess the STE quality and institutional integration and to advise Laboratory Management on the current and future health of the STE. Capability reviews address the STE integration that LANL uses to meet mission requirements. STE capabilities are define to cut across directorates providing a more holistic view of the STE quality, integration to achieve mission requirements, and mission relevance. The scope of these capabilities necessitate that there will be significant overlap in technical areas covered by capability reviews (e.g ., materials research and weapons science and engineering). In addition, LANL staff may be reviewed in different capability reviews because of their varied assignments and expertise. LANL plans to perform a complete review of the Laboratory's STE capabilities (hence staff) in a three-year cycle. The principal product of an external review is a report that includes the review committee's assessments, commendations, and recommendations for STE. The Capability Review Committees serve a dual role of providing assessment of the Laboratory's technical contributions and integration towards its missions and providing advice to Laboratory Management. The assessments and advice are documented in reports prepared by the Capability Review Committees that are delivered to the Director and to the Principal Associate Director for Science, Technology and Engineering (PADSTE). This report will be used by Laboratory Management for STE assessment and planning. The report is also provided to the Department of Energy (DOE) as part of LANL's Annual Performance Plan and to the Los Alamos National Security (LANS) LLC's Science and Technology Committee (STC) as part of its responsibilities to the LANS Board of Governors.

2005-01-01

This proceedings volume contains the papers presented at the 18th colloquium of the Stuttgart University WG on air pollution abatement, which was held jointly with the 5th Stuttgart wood furnaces colloquium this year. This was a good combination as wood has high relevance for air pollution abatement: On the one hand, wood as a fuel will reduce CO2 emissions, improve air quality and save resources. On the other hand, wood combustion may cause fine dust emissions, unpleasant smells and other side effects of incomplete combustion, especially in small furnaces. Fine dust emissions were characterized and future requirements on biomass combustion defined. After this, strategies for optimum design and construction, modern off-gas treatment technologies, high-efficiency combustion technologies, flameless combustion, and efficient combinations of wood furnaces and heat stores were gone into. The utilisation of pellets from cereals and straw was mentioned as well. (orig.)

Recyclables Valorisation as the Best Strategy for Achieving Landfill CO2e Emissions Abatement from Domestic Waste: Game Theory

Directory of Open Access Journals (Sweden)

Paul Taboada-González

2017-07-01

Full Text Available Various nations in the world have developed technologies and strategies for appropriate waste disposal, and to abate waste generation and greenhouse gasses. Alternatives like recovering materials can help, but they require reliable information to improve planning and management. This study quantifies the Carbon dioxide (CO2 emissions produced by the lack of valorisation of materials in a Mexican city. Two waste characterisations in a lower-class neighbourhood were carried out. For the CO2 emission estimation, two scenarios were considered. DEFRA emission factors for waste treatment processes were used. Waste generation was 0.64 kg/capita/day in the first study, and 0.50 kg/capita/day in the second. The CO2eq emissions of collected waste in the neighbourhood were estimated at 1824 kg for 2013 (0.20 kg/capita/day and 1636 kg for 2015 (0.19 kg/capita/day. The behaviour of solid waste management in the city can be explained by the “prisoner’s dilemma” model, studied in game theory, which is ideally suited to analysing situations affected by multiple agents, but requires an accurate understanding of solid waste actors and social implications.

2004-01-01

A novel fluidized electrochemical reactor that integrated advanced electrochemical oxidation with activated carbon (AC) fluidization in a single cell was developed to model pollutant p-nitrophenol (PNP) abatement. AC fluidization could enhance COD removal by 22%-30%. In such a combined process, synergetic effects on PNP and COD removal was found, with their removal rate being enhanced by 137.8% and 97.8%, respectively. AC could be electrochemically regenerated and reused, indicating the combined process would be promising for treatment of biorefractory organic pollutants.

This paper shows a contingent valuation exercise of pollution abatement in remote lakes. In addition to estimating the usual interval data model, it applies a point and interval statistical approach allowing for uncensored data, left-censored data, right-censored data and left- and right-censored data to explore the determinants of willingness-to-pay in a payment card survey. Results suggest that the estimations between models may diverge under certain conditions. Copyright © 2012 Elsevier Ltd. All rights reserved.

One of problems in health environment is organic liquid waste from many pollutant resources. Environmental friendly technology for degrading this waste is ozone which produced by plasma discharge technology, but its capability is limited. However, it is needed a new environmental friendly technology which has stronger capability. This new technology is so called advanced oxidation technology. Advanced oxidation technology is a hybrid of ozone, peroxide, UV light and photo catalyst. In this paper, it is introduced basic principle of hybrid of ozone and titania photo catalyst semiconductor. The capability of organic liquid degradation will be stronger because there is new radical which is produced by chemical reaction between electron-hole pair from photo catalyst titania and water or oxygen. This new radical then degrades this organic pollutant. This technology is used to degrade phenol. (author)

Pharmaceutical abatement in a groundwater (GW), surface water (SW), and secondary effluent (SE) by conventional ozonation, the conventional peroxone (O 3 /H 2 O 2 ), and the electro-peroxone (E-peroxone) processes was compared in batch tests. SE had significantly more fast-reacting dissolved organic matter (DOM) moieties than GW and SW. Therefore, O 3 decomposed much faster in SE than in GW and SW. At specific ozone doses of 0.5-1.5 mg O 3 /mg dissolved organic carbon (DOC), the application of O 3 /H 2 O 2 and E-peroxone process (by adding external H 2 O 2 stocks or in-situ generating H 2 O 2 from cathodic O 2 reduction during ozonation) similarly enhanced the OH yield from O 3 decomposition by ∼5-12% and 5-7% in GW and SW, respectively, compared to conventional ozonation. In contrast, due to the slower reaction kinetics of O 3 with H 2 O 2 than O 3 with fast-reacting DOM moieties, the addition or electro-generation of H 2 O 2 hardly increased the OH yield (<4% increases) in SE. Corresponding to the changes in the OH yields, the abatement efficiencies of ozone-resistant pharmaceuticals (ibuprofen and clofibric acid) increased evidently in GW (up to ∼14-18% at a specific ozone dose of 1.5 mg O 3 /mg DOC), moderately in SW (up to 6-10% at 0.5 mg O 3 /mg DOC), and negligibly in SE during the O 3 /H 2 O 2 and E-peroxone treatment compared to conventional ozonation. These results indicate that similar to the conventional O 3 /H 2 O 2 process, the E-peroxone process can more pronouncedly enhance O 3 transformation to OH, and thus increase the abatement efficiency of ozone-resistant pharmaceuticals in water matrices exerting relatively high ozone stability (e.g., groundwater and surface water with low DOM contents). Therefore, by installing electrodes in existing ozone reactors, the E-peroxone process may provide a convenient way to enhance pharmaceutical abatement in drinking water applications, where groundwater and surface water with low DOM contents are used as

Risk management for sulfur dioxide abatement under multiple uncertainties

In this study, interval-parameter programming, two-stage stochastic programming (TSP), and conditional value-at-risk (CVaR) were incorporated into a general optimization framework, leading to an interval-parameter CVaR-based two-stage programming (ICTP) method. The ICTP method had several advantages: (i) its objective function simultaneously took expected cost and risk cost into consideration, and also used discrete random variables and discrete intervals to reflect uncertain properties; (ii) it quantitatively evaluated the right tail of distributions of random variables which could better calculate the risk of violated environmental standards; (iii) it was useful for helping decision makers to analyze the trade-offs between cost and risk; and (iv) it was effective to penalize the second-stage costs, as well as to capture the notion of risk in stochastic programming. The developed model was applied to sulfur dioxide abatement in an air quality management system. The results indicated that the ICTP method could be used for generating a series of air quality management schemes under different risk-aversion levels, for identifying desired air quality management strategies for decision makers, and for considering a proper balance between system economy and environmental quality.

FCC catalyst technologies expand limits of process capability

International Nuclear Information System (INIS)

Leiby, S.

1992-01-01

This paper reports that over the past 30 or so years, many improvements in fluid catalytic cracking (FCC) operation have been achieved as the result of innovations in catalyst formulation. During the 1990s, new environmental regulations on issues such as reformulated gasoline will place new demands on both the refining industry and catalyst suppliers. An overview of cracking catalyst technology therefore seems in order. Today, high-technology innovations by catalyst manufacturers are rapid, but profit margins are slim. Catalyst formulations are shrouded in secrecy and probably depend almost as much on art as on science. Special formulations for specific cracking applications get the greatest emphasis today. To illustrate this point, OGJ's Worldwide Catalyst Report lists over 200 FCC catalyst designations. Catalysts containing components to enhance gasoline octane now account for about 70% of total U.S. FCC catalyst usage

Canadian capabilities in fusion fuels technology and remote handling

International Nuclear Information System (INIS)

1987-10-01

This report describes Canadian expertise in fusion fuels technology and remote handling. The Canadian Fusion Fuels Technology Project (CFFTP) was established and is funded by the Canadian government, the province of Ontario and Ontario Hydro to focus on the technology necessary to produce and manage the tritium and deuterium fuels to be used in fusion power reactors. Its activities are divided amongst three responsibility areas, namely, the development of blanket, first wall, reactor exhaust and fuel processing systems, the development of safe and reliable operating procedures for fusion facilities, and, finally, the application of these developments to specific projects such as tritium laboratories. CFFTP also hopes to utilize and adapt Canadian developments in an international sense, by, for instance, offering training courses to the international tritium community. Tritium management expertise is widely available in Canada because tritium is a byproduct of the routine operation of CANDU reactors. Expertise in remote handling is another byproduct of research and development of of CANDU facilities. In addition to describing the remote handling technology developed in Canada, this report contains a brief description of the Canadian tritium laboratories, storage beds and extraction plants as well as a discussion of tritium monitors and equipment developed in support of the CANDU reactor and fusion programs. Appendix A lists Canadian manufacturers of tritium equipment and Appendix B describes some of the projects performed by CFFTP for offshore clients

Ammonia emissions from livestock production can have negative impacts on nearby protected sites and ecosystems that are sensitive to eutrophication and acidification. Trees are effective scavengers of both gaseous and particulate pollutants from the atmosphere making tree belts potentially effective landscape features to support strategies aiming to reduce ammonia impacts. This research used the MODDAS-THETIS a coupled turbulence and deposition turbulence model, to examine the relationships between tree canopy structure and ammonia capture for three source types—animal housing, slurry lagoon, and livestock under a tree canopy. By altering the canopy length, leaf area index, leaf area density, and height of the canopy in the model the capture efficiencies varied substantially. A maximum of 27% of the emitted ammonia was captured by tree canopy for the animal housing source, for the slurry lagoon the maximum was 19%, while the livestock under trees attained a maximum of 60% recapture. Using agro-forestry systems of differing tree structures near ‘hot spots’ of ammonia in the landscape could provide an effective abatement option for the livestock industry that complements existing source reduction measures.

2018-01-01

In this paper, we present a transboundary pollution game, in which emission permits trading and pollution abatement costs under learning by doing are considered. In this model, the abatement cost mainly depends on the level of pollution abatement and the experience of using pollution abatement technology. We use optimal control theory to investigate the optimal emission paths and the optimal pollution abatement strategies under cooperative and noncooperative games, respectively. Additionally, the effects of parameters on the results have been examined.

Robust U.S. wind turbine manufacturing capabilities and supply chains are important for the United States to reduce the cost of electricity generated from wind turbines. These capabilities and supply chains are also critical to the invention and commercialization of new wind turbine technologies while providing high-quality jobs. The development of advanced drivetrain technologies for windturbine applications is advancing the state of the art for drivetrain design by producing higher capacity and operating reliability than conventional drivetrains. Advanced drivetrain technologies such as medium-speed and direct-drive generators, silicon-carbide (SiC) IGBT-based power electronics, and high torque density speed increasers require different manufacturing and supply chaincapabilities that present both risks and opportunities for U.S. wind turbine manufacturers and the wind industry as a whole. The primary objective of this project is to assess how advanced drivetrain technologies and trends will impact U.S. wind turbine manufacturing and its supply chains. The U.S. Department of Energy and other industry participants will use the information from this study toidentify domestic manufacturing gaps, barriers, and opportunities for developing U.S. wind turbine manufacturing capabilities and supply chains for next-generation drivetrain technologies. This report also includes recommendations for prioritizing technology areas for possible investments by public, private, or nonprofit entities that will reduce the cost of wind-generated electricity. Suchinvestments foster opportunities to invent and commercialize new wind turbine technologies, and provide high-quality jobs in the United States.

Freer markets and the abatement of carbon emissions. The electricity-generating sector in India

International Nuclear Information System (INIS)

Khanna, Madhu; Zilberman, David

1999-01-01

This paper develops a framework to explore the implications of trade and domestic policy distortions for the magnitude of carbon emissions and for the welfare costs of abating these emissions. An application to the electricity-generating sector in India shows that economic policy reforms can also be effective environmental policy instruments and reduce carbon emissions even in the absence of an emissions tax. This reduction in emissions is accompanied by an increase in domestic welfare, an increase in electricity output, and conservation of coal. Coordinating trade and domestic policy reform with an emissions tax policy reduces emissions further, while leading to gains in welfare that are greater than those under an emissions tax policy alone

When should green technology support policies supplement the carbon price? The case of the electricity sector

International Nuclear Information System (INIS)

Lecuyer, Oskar

2013-01-01

This thesis contributes to the literature on optimal policy choice. It studies the use of policy combinations to mitigate greenhouse gases emissions from electricity production. One finding applies to cases where uncertainty is such that the risk of a nil carbon price cannot be excluded. A cap on emissions alone may then not trigger enough abatements, justifying the addition of e.g. a renewable subsidy. When considering a transition toward a carbon free electricity sector, capital accumulation causes complex dynamic effects to happen. We find that decisions taken by comparing the leveled costs of abatement technologies, even including carbon costs, would favor intermediate technologies (e.g. gas plants) to the detriment of more-expensive but lower-carbon technologies (renewable power), leading to a suboptimal investment schedule. This thesis also studies the effects of marginal policy changes in a mix comprising the main French instruments. We find that surprisingly, adding a tariff for renewables financed by a tax on electricity consumption to a cap on emissions and a subsidy for energy efficiency will reduce the consumer electricity price when the non-renewable production is fixed and does not depend on the carbon price. The assessment of the French climate policies in the electricity sector shows that overlapping policies for mitigation may be justified by multiple carbon price failures, even if the ideal long-term policy mix depends on the carbon price trajectory.

Managing key capabilities: A challenge for nuclear plant building companies

International Nuclear Information System (INIS)

Pascal Corbel

2003-01-01

The nuclear plant building industry faces a paradoxical situation. The use of nuclear reactors to produce energy for civil purposes is both a promising technology, with potentially huge outlets, and a technology facing declining demand. One of the key problems is then: how to maintain the capabilities necessary to benefit from the potential recovery? The resource-based view of strategic management has shown the importance of different types of resources and capabilities in gaining a sustainable competitive advantage. Successful incumbents in the market of nuclear station building have built those kinds of distinctive capabilities that give them a competitive advantage over potential new entrants. But we show that, without a permanent activity in plant building, preserving those capabilities necessitates specific strategic action. We firstly develop the argument that the nuclear plant building industry is in a paradoxical situation in terms of demand and technical performance trends. Secondly, we try to identify the key capabilities of the incumbents. We show that companies in that field use mainly three types of distinctive capabilities: pure technical and scientific knowledge in direct relation to the use of nuclear as an energy generator, competences in risk management and competences in large project management, including financing. Thirdly, we show that although some of those capabilities are used through other nuclear-related activities such as plant maintenance or fuel supply, some of them necessitate taking strategic actions in order to be preserved. We argue that this should be a priority of nuclear equipment company managers in the next few years. (author)

When we don't know the costs or the benefits: adaptive strategies for abating climate change

International Nuclear Information System (INIS)

Lempert, R.J.; Schlesinger, M.E.; Bankes, S.C.

1996-01-01

Most quantitative studies of climate-change policy attempt to predict the greenhouse-gas reduction plan that will have the optimum balance of long-term costs and benefits. The authors find that the large uncertainties associated with the climate-change problem can make the policy prescriptions of this traditional approach unreliable. In this study the authors construct a large uncertainty space that includes the possibility of large and/or abrupt climate changes and/or of technology breakthroughs that radically reduce projected abatement costs. Computational experiments are used on a linked system of climate and economic models to compare the performance of a simple adaptive strategy - one that can make midcourse corrections based on observations of the climate and economic systems - and two commonly advocated 'best-estimate' policies based on different expectations about the long-term consequences of climate change. It was found that the 'Do-a-Little' and 'Emissions-Stabilization' best-estimate policies perform well in the respective regions of the uncertainty space where their estimates are valid, but can fail severely in those regions where their estimates are wrong. In contrast, the adaptive strategy can make midcourse corrections and avoid significant errors. While its success is no surprise, the adaptive-strategy approach provides an analytic framework to examine important policy and research issues that will likely arise as society adapts to climate change, which cannot be easily addressed in studies using best-estimate approaches. 44 refs., 15 figs., 3 tabs

Technological substitution options for controlling greenhouse gas emissions

International Nuclear Information System (INIS)

Barbier, E.B.; Burgess, J.C.; Pearce, D.W.

1991-01-01

This chapter is concerned with technological options for greenhouse gas substitution. The authors interpret the term substitution to exclude energy conservation/efficiency measures, investments in afforestation (sinks), and greenhouse gas removal or abatement technologies. Their working definition of greenhouse gas substitution includes (1) replacement technologies, for example, substituting a greenhouse gas technology with a nongreenhouse gas technology; and (2) reduction technologies, for example, substituting a greenhouse gas technology with an alternative technology that reduces greenhouse gas emissions. Essentially, replacement technologies involve 100 percent reduction in CO 2 ; reduction technologies involve a partial reduction in CO 2 . Of the man-made sources of greenhouse gases, energy is the most important and is expected to contribute to at least half of the global warming effect in the near future. The majority of this impact is from fossil fuel combustion as a source of carbon dioxide (CO 2 ), although fossil fuels also contribute significantly to methane (CH 4 ), to nitrous oxide (N 2 O), and to low-level ozone (O 3 ) through production of various nitrogen gases (NO x ) and carbon monoxide (CO). This study analyzes the available greenhouse gas substitutions and their costs. The authors concentrate particularly on substitutions for fossil-fuel combustion and CFC production and consumption. They conclude by summarizing the potential for greenhouse gas substitution, the cost-effectiveness of the various options and the design of incentives for substitution

Cost decreases in environmental technology. Evidence from four case studies

Energy Technology Data Exchange (ETDEWEB)

Oosterhuis, F. [Instituut for Environmental Studies, Vrije Universiteit VU, Amsterdam (Netherlands)

2007-07-15

The cost of a new technology tends to decrease as its uptake grows, and environmental technology is no exception to this general rule. Factors that can bring about such cost reductions include economies of scale, 'learning-by-doing', incremental technological improvements, and growing competition. In preparing environmental policies, the potential for future cost reductions is often disregarded. The present study aims to provide some additional empirical evidence on the cost decreases in environmental technology and the factors that lie behind them. To this end, four exemplary case studies have been selected. The first case (NOx emission abatement by Selective Catalytic Reduction (SCR)), shows a wide variety in cost estimates, without a clear trend. This is even true for the costs of a fairly homogeneous type of investment (SCR in coal fired power plants). Nevertheless, it is clear that an important cost decrease has been achieved by prolonging the lifetime of the catalyst, which is one of the main cost components in SCR. In the second case (NH3 emission abatement by chemical air scrubbers in pig farming) there is not yet sufficient experience with the technology to draw conclusions on the development of costs. However, it is already clear that economizing on the capacity of the system can contribute to important cost savings. Three-way catalytic converters in cars have shown significant price decreases following their large scale introduction on the European market in the early 1990s. Probably economies of scale have played an important role in this case, as the size of the market made mass production possible. To some extent, cost reductions may also be attributed to improvements such as the need for less materials (e.g. platinum). Furthermore, the performance of catalytic converters has improved, implying that the cost per unit of emission reduction has decreased even more than the cost of the device itself.

As a condition of the modified National Pollutant Discharge Elimination System (NPDES) permit issued to the Oak Ridge Gaseous Diffusion Plant (ORGDP; now referred to as the Oak Ridge K-25 Site) on September 11, 1986, a Biological Monitoring and Abatement Program (BMAP) was developed for the receiving stream (Mitchell Branch or K-1700 stream). On October 1, 1992, a renewed NPDES permit was issued for the K-25 Site. A biological monitoring plan was submitted for Mitchell Branch, Poplar Creek, Poplar Creek Embayment of the Clinch River and any unnamed tributaries of these streams. The objectives of BMAP are to (1) demonstrate that the effluent limitations established for the Oak Ridge K-25 Site protect and maintain the use of Mitchell Branch for growth and propagation of fish and other aquatic life and (2) document the effects on stream biota resulting from operation of major new pollution abatement facilities, including the Central Neutralization Facility (CNF) and the Toxic Substances Control Act (TSCA) incinerator. The BMAP consists of four tasks: (1) toxicity monitoring; (2) bioaccumulation monitoring; (3) assessment of fish health; and (4) instream monitoring of biological communities, including benthic macroinvertebrates and fish. This document, the third in a series, reports on the results of the Oak Ridge K-25 Site BMAP; it describes studies that were conducted over various periods of time between June 1990 and December 1993, although monitoring conducted outside this time period is included, as appropriate.

Key Future Engineering Capabilities for Human Capital Retention

Science.gov (United States)

Sivich, Lorrie

Projected record retirements of Baby Boomer generation engineers have been predicted to result in significant losses of mission-critical knowledge in space, national security, and future scientific ventures vital to high-technology corporations. No comprehensive review or analysis of engineering capabilities has been performed to identify threats related to the specific loss of mission-critical knowledge posed by the increasing retirement of tenured engineers. Archival data from a single diversified Fortune 500 aerospace manufacturing engineering company's engineering career database were analyzed to ascertain whether relationships linking future engineering capabilities, engineering disciplines, and years of engineering experience could be identified to define critical knowledge transfer models. Chi square, logistic, and linear regression analyses were used to map patterns of discipline-specific, mission-critical knowledge using archival data of engineers' perceptions of engineering capabilities, key developmental experiences, and knowledge learned from their engineering careers. The results from the study were used to document key engineering future capabilities. The results were then used to develop a proposed human capital retention plan to address specific key knowledge gaps of younger engineers as veteran engineers retire. The potential for social change from this study involves informing leaders of aerospace engineering corporations on how to build better quality mentoring or succession plans to fill the void of lost knowledge from retiring engineers. This plan can secure mission-critical knowledge for younger engineers for current and future product development and increased global competitiveness in the technology market.

2006-01-01

NASA's In-space Propulsion (ISP) Technology Project is developing new propulsion technologies that can enable or enhance near and mid-term NASA science missions. The Solar Electric Propulsion (SEP) technology area has been investing in NASA s Evolutionary Xenon Thruster (NEXT), the High Voltage Hall Accelerator (HiVHAC), lightweight reliable feed systems, wear testing, and thruster modeling. These investments are specifically targeted to increase planetary science payload capability, expand the envelope of planetary science destinations, and significantly reduce the travel times, risk, and cost of NASA planetary science missions. Status and expected capabilities of the SEP technologies are reviewed in this presentation. The SEP technology area supports numerous mission studies and architecture analyses to determine which investments will give the greatest benefit to science missions. Both the NEXT and HiVHAC thrusters have modified their nominal throttle tables to better utilize diminished solar array power on outbound missions. A new life extension mechanism has been implemented on HiVHAC to increase the throughput capability on low-power systems to meet the needs of cost-capped missions. Lower complexity, more reliable feed system components common to all electric propulsion (EP) systems are being developed. ISP has also leveraged commercial investments to further validate new ion and hall thruster technologies and to potentially lower EP mission costs.

Renewable energy and CO_2 abatement in Italy

Marcantonini, Claudio; Valero, Vanessa

2017-01-01

In order to combat global warming, Italy has committed to reduce its CO_2 emissions. To this end, it has significantly encouraged renewable energy development through a variety of support schemes, ranging from green certificates to feed-in and premium tariffs. As a result, the production of electricity from renewable energy sources, in particular from solar and wind energy, has risen considerably over the past years. In this paper we review the Italian support schemes for wind and solar energy and estimate the cost of abating CO_2 emissions by generating electricity from these two sources of energy for the period 2008–2011. The results show that the average costs for wind were around 165 €/tCO_2. For solar, they were much higher, around 1000 €/tCO_2, as solar energy received much higher remunerations than wind energy. These costs were much higher than in Germany. This was due to the differences between the level of incentives and the different power systems. - Highlights: • We estimate the cost of reducing CO_2 emissions by wind and solar energy in Italy in 2008–2011. • The average costs for wind were around 165 €/tCO_2. • The average costs for solar were much higher, around 1000 €/tCO_2. • Those costs were much higher than in Germany. • This was due to the differences in the levels of incentives and to the different power systems.

Background The demand for an eHealth-ready and adaptable workforce is placing increasing pressure on universities to deliver eHealth education. At present, eHealth education is largely focused on components of eHealth rather than considering a curriculum-wide approach. Objective This study aimed to develop a framework that could be used to guide health curriculum design based on current evidence, and stakeholder perceptions of eHealth capabilities expected of tertiary health graduates. Methods A 3-phase, mixed-methods approach incorporated the results of a literature review, focus groups, and a Delphi process to develop a framework of eHealth capability statements. Results Participants (N=39) with expertise or experience in eHealth education, practice, or policy provided feedback on the proposed framework, and following the fourth iteration of this process, consensus was achieved. The final framework consisted of 4 higher-level capability statements that describe the learning outcomes expected of university graduates across the domains of (1) digital health technologies, systems, and policies; (2) clinical practice; (3) data analysis and knowledge creation; and (4) technology implementation and codesign. Across the capability statements are 40 performance cues that provide examples of how these capabilities might be demonstrated. Conclusions The results of this study inform a cross-faculty eHealth curriculum that aligns with workforce expectations. There is a need for educational curriculum to reinforce existing eHealth capabilities, adapt existing capabilities to make them transferable to novel eHealth contexts, and introduce new learning opportunities for interactions with technologies within education and practice encounters. As such, the capability framework developed may assist in the application of eHealth by emerging and existing health care professionals. Future research needs to explore the potential for integration of findings into workforce development

2010-01-01

Traditional odor control methods are limitative technically and economically for the abatement of odor from pesticide factory due to its toxicity and complicated composition. Non-thermal plasma (NTP) methods, typically characterized by high removal efficiency, energy yields and good economy, offer possible alternative solutions. This paper provides laboratory scale experimental data on the removal of simulated odors from pesticide factory with various humidity (0-0.8 vol%) and oxygen contents (0-21%) by a dielectric barrier discharge (DBD) reactor. Peak voltage and initial dimethylamine (DML) concentration are important factors that influence the DML removal efficiency and energy yield. The conversion of DML of 761 mg/m 3 reaches 100% at a peak voltage of 41.25 kV. Under the experiment conditions, the conversion of DML increases with an increase of oxygen contents. And the highest DML conversion was achieved with the gas stream containing 0.3% water. Simultaneously, the concentration of O 3 and OH radical in reactor was measured. Higher conversion, higher energy yield and fewer byproducts were found in mixed odor (DML + dimethyl sulfide (DMS)) treatment than that in single odor treatment. The energy yield is promoted from 2.13 to 5.20 mg/kJ.

2012-01-01

NASA is considering a number of future human space exploration mission concepts. Although detailed requirements and vehicle architectures remain mostly undefined, near-term technology investment decisions need to be guided by the anticipated capabilities needed to enable or enhance the mission concepts. This paper describes a roadmap that NASA has formulated to guide the development of Environmental Control and Life Support Systems (ECLSS) capabilities required to enhance the long-term operation of the International Space Station (ISS) and enable beyond-Low Earth Orbit (LEO) human exploration missions. Three generic mission types were defined to serve as a basis for developing a prioritized list of needed capabilities and technologies. Those are 1) a short duration micro gravity mission; 2) a long duration transit microgravity mission; and 3) a long duration surface exploration mission. To organize the effort, ECLSS was categorized into three major functional groups (atmosphere, water, and solid waste management) with each broken down into sub-functions. The ability of existing, flight-proven state-of-the-art (SOA) technologies to meet the functional needs of each of the three mission types was then assessed. When SOA capabilities fell short of meeting the needs, those "gaps" were prioritized in terms of whether or not the corresponding capabilities enable or enhance each of the mission types. The resulting list of enabling and enhancing capability gaps can be used to guide future ECLSS development. A strategy to fulfill those needs over time was then developed in the form of a roadmap. Through execution of this roadmap, the hardware and technologies needed to enable and enhance exploration may be developed in a manner that synergistically benefits the ISS operational capability, supports Multi-Purpose Crew Vehicle (MPCV) development, and sustains long-term technology investments for longer duration missions. This paper summarizes NASA s ECLSS capability roadmap

Over the past several decades, physicists have made seminal contributions to technological capabilities that have enabled the U.S. intelligence community to provide unexpected and unparalleled information to our nation's decision makers and help dispel the cloud of uncertainty they face in dealing with crises and challenges around the world. As we look to the future, we recognize that the ever-quickening pace of changes in the world and the threats we must confront demand continued innovation and improvement in the capabilities needed to provide the information on which our leaders depend. This talk will focus on some of the major technological challenges that the intelligence community faces in the coming years, and the many ways that physicists can help to overcome those challenges. The potential impact of physicists on the future capabilities of the US intelligence community is huge. In addition to the more obvious and direct impact through research in areas ranging from novel sensors to quantum information science, the unique approach physicists bring to a problem can also have an indirect but important effect by influencing how challenges in areas ranging from cybersecurity to advanced analytics are approached and solved. Several examples will be given.

Medical institutions are eager to introduce new information technology to improve patient safety and clinical efficiency. However, the acceptance of new information technology by medical personnel plays a key role in its adoption and application. This study aims to investigate whether perceived organizational learning capability (OLC) is associated with user acceptance of information technology among operating room nurse staff. Nurse anesthetists and operating room nurses were recruited in this questionnaire survey. A pilot study was performed to ensure the reliability and validity of the translated questionnaire, which consisted of 14 items from the four dimensions of OLC, and 16 items from the four constructs of user acceptance of information technology, including performance expectancy, effort expectancy, social influence, and behavioral intention. Confirmatory factor analysis was applied in the main survey to evaluate the construct validity of the questionnaire. Structural equation modeling was used to test the hypothetical relationships between the four dimensions of user acceptance of information technology and the second-ordered OLC. Goodness of fit of the hypothetic model was also assessed. Performance expectancy, effort expectancy, and social influence positively influenced behavioral intention of users of the clinical information system (all p < 0.001) and accounted for 75% of its variation. The second-ordered OLC was positively associated with performance expectancy, effort expectancy, and social influence (all p < 0.001). However, the hypothetic relationship between perceived OLC and behavioral intention was not significant (p = 0.87). The fit statistical analysis indicated reasonable model fit to data (root mean square error of approximation = 0.07 and comparative fit index = 0.91). Perceived OLC indirectly affects user behavioral intention through the mediation of performance expectancy, effort expectancy, and social influence in the operating room

We have developed several technologies for protecting automated teller machines. These technologies are based mainly on pattern recognition and are used to implement various self-defence functions. They include (i) banknote recognition and information retrieval for preventing machines from accepting counterfeit and damaged banknotes and for retrieving information about detected counterfeits from a relational database, (ii) form processing and character recognition for preventing machines from accepting remittance forms without due dates and/or insufficient payment, (iii) person identification to prevent machines from transacting with non-customers, and (iv) object recognition to guard machines against foreign objects such as spy cams that might be surreptitiously attached to them and to protect users against someone attempting to peek at their user information such as their personal identification number. The person identification technology has been implemented in most ATMs in Japan, and field tests have demonstrated that the banknote recognition technology can recognise more then 200 types of banknote from 30 different countries. We are developing an "advanced intelligent ATM" that incorporates all of these technologies.

The performance of multimetal-(Cu, Cr, Zn, Ni, and Co)-ion-exchanged zeolite A prepared from both a commercial-grade sample and one produced from coal fly ash in methane emissions abatement was evaluated in this study. The ion-exchange process was used to load the metal ions in zeolite A samples. The methane conversion efficiency by the samples was studied under various parameters including the amount of metal loading (7.3-19.4 wt%), reaction temperature (25-500 degrees C), space velocity (8400-41 900 h(-1)), and methane concentration (0.5-3.2 vol %). At 500 degrees C, the original commercial-grade zeolite A catalyzed 3% of the methane only, whereas the addition of different percentages of metals in the sample enhanced the methane conversion efficiency by 40-85%. Greater methane conversion was observed by increasing the percentage of metals added to the zeolite even though the BET surface area of the zeolite consequently decreased. Higher percentage methane conversion over the multi-ion-exchanged samples was observed at lower space velocities indicating the importance of the mass diffusion of reactants and products in the zeolite. Compared to the multi-ion-exchanged zeolite A prepared from the commercial-grade zeolite, the one produced from coal fly ash demonstrated similar performances in methane emissions abatement, showing the potential use of this low cost recycled material in gaseous pollutant treatment.

This is the tenth Quarterly Technical Report for DOE Cooperative Agreement No: DE-FC26-00NT40954. The goal of the project is to develop and demonstrate a software framework to enable virtual simulation of Vision 21 plants. During the last quarter much progress was made in software development. The CO wrapper template was developed for the integration of Alstom Power proprietary code INDVU. The session management tasks were completed. The multithreading capability was made functional so that user of the integrated simulation may directly interact with the CFD software. The V21-Controller and the Fluent CO wrapper were upgraded to CO v.1.0. The testing and debugging of the upgraded software is ongoing. Testing of the integrated software was continued. A list of suggested GUI enhancements was made. Remote simulation capability was successfully tested using two networked Windows machines. Work on preparing the release version progressed: CFD database was enhanced, a convergence detection capability was implemented, a Configuration Wizard for low-order models was developed, and the Configuration Wizard for Fluent was enhanced. During the last quarter good progress was made in software demonstration. Various simplified versions of Demo Case 1 were used to debug Configuration Wizard and V21-Controller. The heat exchanger model in FLUENT was calibrated and the energy balance was verified. The INDVU code was integrated into the V21-Controller, and the integrated model is being debugged. A sensitivity loop was inserted into Demo Case 2 to check whether the simulation converges over the desired load range. Work on converting HRSGSIM code to run in batch mode was started. Work on calibrating Demo Case 2 was started.

The energy crisis looming before the United States can be resolved only by an approach that integrates a 'portfolio' of options. Nuclear energy, already an important element in the portfolio, should play an even more significant role in the future as the U.S. strives to attain energy independence and reduce carbon emissions. The DOE Office of Nuclear Energy asked Battelle Memorial Institute to obtain input from the commercial power generation industry on industry's vision for nuclear energy over the next 30-50 years. With this input, Battelle was asked to generate a set of research and development capabilities necessary for DOE to support the anticipated growth in nuclear power generation. This presentation, based on the report generated for the Office of Nuclear Energy, identifies the current and future nuclear research and development capabilities required to make this happen. The capabilities support: (1) continued, safe operation of the current fleet of nuclear plants; (2) the availability of a well qualified and trained workforce; (3) demonstration of the next generation nuclear plants; (4) development of a sustainable fuel cycle; (5) advanced technologies for maximizing resource utilization and minimization of waste and (6) advanced modeling and simulation for rapid and reliable development and deployment of new nuclear technologies. In order to assure these capabilities are made available, a Strategic Nuclear Energy Capability Initiative is proposed to provide the required resources during this critical period of time.

Catalytic oxidation of chlorinated volatile organic compounds, dichloromethane and perchloroethylene. New knowledge for the industrial CVOC emission abatement

Energy Technology Data Exchange (ETDEWEB)

Pitkaeaho, S.

2013-09-01

The releases of chlorinated volatile organic compounds (CVOCs) are controlled by strict regulations setting high demands for the abatement systems. Low temperature catalytic oxidation is a viable technology to economically destroy these often refractory emissions. Catalysts applied in the oxidation of CVOCs should be highly active and selective but also maintain a high resistance towards deactivation. In this study, a total of 33 different {gamma}-Al{sub 2}O{sub 3} containing metallic monoliths were studied in dichloromethane (DCM) and 25 of them in perchloroethylene (PCE) oxidation. The active compounds used were Pt, Pd, Rh or V{sub 2}O{sub 5} alone or as mixtures. The catalysts were divided into three different testing sets: industrial, CVOC and research catalysts. ICP-OES, physisorption, chemisorption, XRD, UV-vis DRS, isotopic oxygen exchange, IC, NH{sub 3}-TPD, H{sub 2}-TPR and FESEM-EDS were used to characterise the catalysts. Screening of the industrial catalysts revealed that the addition of V{sub 2}O{sub 5} improved the performance of the catalyst. DCM abatement was easily affected by the addition of VOC or water, but the effect on the PCE oxidation was only minor. Based on these screening tests, a set of CVOC catalysts were developed and installed into an industrial incinerator. The comparison between the laboratory and industrial scale studies showed that DCM oxidation in an industrial incinerator could be predicted relatively well. Instead, PCE was always seen to be oxidised far better in an industrial unit indicating that the transient oxidation conditions are beneficial for the PCE oxidation. Before starting the experiments with research catalysts, the water feed was optimised to 1.5 wt.%. Besides enhancing the HCl yields, water improved the DCM and PCE conversions. In the absence of oxygen, i.e. during destructive adsorption, the presence of water was seen to have an even more pronounced effect on the HCl formation and on the catalysts

Water scarcity is one of the major concerns worldwide. In order to secure this appreciated natural resource, management and development of water treatment technologies are mandatory. One feasible alternative is the consideration of water recycling/reuse at the household scale. Here, the treatment of actual washing machine effluent by electrochemical advanced oxidation processes was considered. Electrochemical oxidation and electro-Fenton technologies can be applied as decentralized small-scale water treatment devices. Therefore, efficient decolorization and total organic abatement have been followed. The results demonstrate the promising performance of solar photoelectro-Fenton process, where complete color and organic removal was attained after 240 min of treatment under optimum conditions by applying a current density of 66.6 mA cm -2 . Thus, electrochemical technologies emerge as promising water-sustainable approaches.

Full Text Available Knowledge about the capabilities of a production system is an important issue. The three- dimensional (3-D printing (drop-on-bed process has become a well-established Additive Manufacturing (AM technology. Initially intended for use mainly as a concept modeller, its scope of application has expanded to include, among others, fit and functional models, pattern-making for casting and moulding processes, rapid tooling, and medical and architectural models. This growth in applications has stimulated a reciprocal improvement in available materials and the technological capabilities of 3-D printing, such as accuracy, strength and elongation, surface finish, build time, and cost. These factors are of significance to users who want to control their processes better and to designers who want to define their expectations and determine their requirements. Thus this paper aims to provide a technical update, highlighting the influence level of different factors on a system’s capabilities. This paper uses the example of the ZPrinter 310 system from the Z Corporation, applies appropriate statistical techniques, and takes into consideration the latest material and machine developments, in order to report on the current improvements of the capability profile of this important process.

CO2 emissions abatement in the Nordic carbon-intensive industry – An end-game in sight?

2015-01-01

Analysing different future trajectories of technological developments we assess the prospects for Nordic carbon-intensive industries to significantly reduce direct CO 2 emissions in the period 2010–2050. This analysis covers petroleum refining, integrated iron and steel production, and cement manufacturing in the four largest Nordic countries of Denmark, Finland, Norway, and Sweden. Our results show that the implementation of currently available abatement measures will not be enough to meet the ambitious emissions reduction targets envisaged for the Year 2050. We show how an extensive deployment of CCS (carbon capture and storage) could result in emissions reductions that are in line with such targets. However, large-scale introduction of CCS would come at a significant price in terms of energy use and the associated flows of captured CO 2 would place high requirements on timely planning of infrastructure for the transportation and storage of CO 2 . Further the assessment highlights the importance of, especially in the absence of successful deployment of CO 2 capture, encouraging increased use of biomass in the cement and integrated iron and steel industries, and of promoting the utilisation of alternative raw materials in cement manufacturing to complement efforts to improve energy efficiency. - Highlights: • Scenarios exploring the potential for reducing CO 2 emissions in Nordic industry. • Current measures not sufficient to comply with stringent emission reduction targets. • CCS enables carbon-intensive industries to comply with stringent reduction targets. • CCS would come at a high price in terms of energy use. • Without CO 2 capture increased use of biomass and alternative raw materials vital

This abstract discussed recent advances in stack technology by Ballard Power Systems. The technology department of this Canadian-owned company exhibited the capability of a single proton exchange membrane fuel cell (PEMFC) stack design to demonstrate that cost reduction, freeze start capability from -20 degrees C and durability under an automotive dynamic operating cycle are comparable to that experienced by a fuel cell stack in an actual vehicle. A technology road map has been developed by the company to define a path to the commercial viability of the PEMFC stack by 2010. Key target parameters for cost reduction, durability, freeze start and stack power density were described in detail along with demonstrated historical capability and details of how the company will achieve its required targets. refs., tabs., figs.

In the development of a superior short-haul operating system, terminal-configured vs cruise-configured vehicles are evaluated. CTOL, STOL, and VTOL aircraft of various types are discussed. In the field of noise abatement, it is shown that flight procedural techniques are capable of supplementing ?quiet engine' technology.

Analytical Chemistry Core Capability Assessment - Preliminary Report

Barr, Mary E.; Farish, Thomas J.

The concept of 'core capability' can be nebulous one. Even at a fairly specific level, where core capability equals maintaining essential services, it is highly dependent upon the perspective of the requestor. Samples are submitted to analytical services because the requesters do not have the capability to conduct adequate analyses themselves. Some requests are for general chemical information in support of R and D, process control, or process improvement. Many analyses, however, are part of a product certification package and must comply with higher-level customer quality assurance requirements. So which services are essential to that customer - just those for product certification? Does the customer also (indirectly) need services that support process control and improvement? And what is the timeframe? Capability is often expressed in terms of the currently utilized procedures, and most programmatic customers can only plan a few years out, at best. But should core capability consider the long term where new technologies, aging facilities, and personnel replacements must be considered? These questions, and a multitude of others, explain why attempts to gain long-term consensus on the definition of core capability have consistently failed. This preliminary report will not try to define core capability for any specific program or set of programs. Instead, it will try to address the underlying concerns that drive the desire to determine core capability. Essentially, programmatic customers want to be able to call upon analytical chemistry services to provide all the assays they need, and they don't want to pay for analytical chemistry services they don't currently use (or use infrequently). This report will focus on explaining how the current analytical capabilities and methods evolved to serve a variety of needs with a focus on why some analytes have multiple analytical techniques, and what determines the infrastructure for these analyses. This information will be
