    2001-02-01

    General public environmental awareness and education is increasing, therefore stimulating the demand for reliable, objective and comparable information about products' environmental performances. The recently published standard series ISO 14040 and ISO 14025 are normalizing the preparation of Environmental Product Declarations (EPDs) containing comprehensive information relevant to a product's environmental impact during its life cycle. So far, only a few environmentally leading manufacturing organizations have experimented the preparation of EPDs (mostly from Europe), demonstrating its great potential as a marketing weapon. However the preparation of EPDs is a complex process, requiring collection and analysis of massive amounts of information coming from disparate sources (suppliers, sub-contractors, etc.). In a foreseeable future, the streamlining of the EPD preparation process will require product manufacturers to adapt their information systems (ERP, MES, SCADA) in order to make them capable of gathering, and transmitting the appropriate environmental information. It also requires strong functional integration all along the product supply chain in order to ensure that all the information is made available in a standardized and timely manner. The goal of the present paper is two fold: first to propose a transitional model towards green supply chain management and EPD preparation; second to identify key technologies and methodologies allowing to streamline the EPD process and subsequently the transition toward sustainable product development

    This reports for the Swiss Federal Office of Energy (SFOE) presents the results of a study made on the possible ways of declaring product information on cars. The basic elements of such a declaration are discussed and a recommendation for an energy label for cars is presented. The report discusses the fundamental questions posed such as how long a label should be valid, if comparisons should be made and if it is to be based on CO 2 -emissions or on fuel consumption. Also, the criteria to be used for comparisons - such as vehicle weight, size or power - are looked at and methods of classification are examined along with data fundamentals. Further, the expectations placed on the product declarations with respect to their energetic and economic impact are discussed. The design of the label and the legislature on which it is based are discussed and initial reactions of the automobile industry are noted. The report is rounded off by a discussion of the effects of the declaration in relation to other instruments that have been proposed

  6. Life cycle assessment of railways and rail transports - Application in environmental product declarations (EPDs) for the Bothnia Line

    Stripple, Haakan; Uppenberg, Stefan

    2010-09-15

    Environmental aspects are today highly important issues in the transport sector especially from a society perspective. Most likely, our society is facing considerable changes in the transport sector due to changes in the energy/environmental situation in the future. Strategic decisions concerning the development of the transport sector must be based on solid facts concerning both the transport infrastructure and the transport traffic on the infrastructure. The transport infrastructure is often complex and difficult to analyse but of great interest in a society perspective. In this project, we have performed a comprehensive view of a modern railway infrastructure system including the traffic on the infrastructure. A Life Cycle Assessment (LCA) methodology has been used for the study and several LCA models of the railway system have been designed. Due to the complexity of the models, several general railway component models have been developed. The component models can then be integrated to form a large model of an entire railway system. The component models (sub-models) are: 'Railway track foundation model', 'Railway track model', 'Railway electric power and control system model', 'Railway tunnel model', 'Railway bridge model', 'Railway passenger station and freight terminal model', 'Passenger and freight train model including train operation'. The LCA models have then been used to analyse the environmental performance of the Bothnia Line and to develop Environmental Product Declarations (EPDs) for the Bothnia Line

    As a core product category rule (PCR), EN 15804 defines rules for conducting the life cycle assessment (LCA) of building products in the context of environmental product declarations (EPDs). This European standard is complemented by EN 16485, which provides further guidance for specific aspects for the LCA of wood and wood-based construction products. For all life cycle stages under consideration, the renewable and non-renewable primary energy employed for energy generation or material use is accounted for. Furthermore, the inputs and outputs of secondary materials (SM), renewable secondary fuels (RSF) and non-renewable secondary fuels (NRSF) have to be reported. Especially in the end-of life stage as well as in the production stage, the standards do not exactly rule the accounting method of the primary energy contained in SM, RSF and NRSF. As both standards leave room for interpretation, we wrote this discussion article to introduce this issue to the LCA community and to present our developed accounting specifications. In general, we consider EN 15804 and EN 16485 as helpful tools for the LCA of building products. We hope that our ideas on certain aspects contribute to a better understanding of the standards, possibly leading to further improvement in the course of the standardization process.

  11. Declarative Modeling for Production Order Portfolio Scheduling

    Directory of Open Access Journals (Sweden)

    Banaszak Zbigniew

    2014-12-01

    Full Text Available A declarative framework enabling to determine conditions as well as to develop decision-making software supporting small- and medium-sized enterprises aimed at unique, multi-project-like and mass customized oriented production is discussed. A set of unique production orders grouped into portfolio orders is considered. Operations executed along different production orders share available resources following a mutual exclusion protocol. A unique product or production batch is completed while following a given activity’s network order. The problem concerns scheduling a newly inserted project portfolio subject to constraints imposed by a multi-project environment The answers sought are: Can a given project portfolio specified by its cost and completion time be completed within the assumed time period in a manufacturing system in hand? Which manufacturing system capability guarantees the completion of a given project portfolio ordered under assumed cost and time constraints? The considered problems regard finding a computationally effective approach aimed at simultaneous routing and allocation as well as batching and scheduling of a newly ordered project portfolio subject to constraints imposed by a multi-project environment. The main objective is to provide a declarative model enabling to state a constraint satisfaction problem aimed at multi-project-like and mass customized oriented production scheduling. Multiple illustrative examples are discussed.

  12. Hippocampal declarative memory supports gesture production: Evidence from amnesia.

    Hilverman, Caitlin; Cook, Susan Wagner; Duff, Melissa C

    2016-12-01

    Spontaneous co-speech hand gestures provide a visuospatial representation of what is being communicated in spoken language. Although it is clear that gestures emerge from representations in memory for what is being communicated (De Ruiter, 1998; Wesp, Hesse, Keutmann, & Wheaton, 2001), the mechanism supporting the relationship between gesture and memory is unknown. Current theories of gesture production posit that action - supported by motor areas of the brain - is key in determining whether gestures are produced. We propose that when and how gestures are produced is determined in part by hippocampally-mediated declarative memory. We examined the speech and gesture of healthy older adults and of memory-impaired patients with hippocampal amnesia during four discourse tasks that required accessing episodes and information from the remote past. Consistent with previous reports of impoverished spoken language in patients with hippocampal amnesia, we predicted that these patients, who have difficulty generating multifaceted declarative memory representations, may in turn have impoverished gesture production. We found that patients gestured less overall relative to healthy comparison participants, and that this was particularly evident in tasks that may rely more heavily on declarative memory. Thus, gestures do not just emerge from the motor representation activated for speaking, but are also sensitive to the representation available in hippocampal declarative memory, suggesting a direct link between memory and gesture production.

    Burri, A.

    2008-07-01

    This final report for the Swiss Federal Office of Energy (SFOE) reports on a project that looked at the optimisation of cooling technology used in small refrigerators. This optimisation alone is considered as being not sufficient to increase the market perspectives for efficient refrigeration units. In contrast to household units, no energy declaration standards exist for the type of mini-bar used in hotel rooms. An 'Energy Declaration - Small Refrigerator' form created as a part of this project is discussed which makes it easier to compare the energy costs of various units. The form is based on uniform criteria, and increases the market perspectives for the most efficient units, even if they are somewhat more expensive. The Swiss Federal Office of Energy is now supplying this form (in German, French and Italian) to all manufacturers and vendors of small refrigerators. The vendor can fill out this form and include it in his offer. Likewise, the customer can request the form from the vendor. In this form the total energy costs for ten years of operation are added to the purchase price, so that the customer can obtain a clear indication of total life cycle costs.

    Full Text Available The declarative programming by declarative languages is clearly the best option a programmer can have for a completely readable, flexible and extensible code. Today, the economics of programming is clearly focused on the declarative paradigm while most imperative languages are trying to become cost effective by using new added declarative features for productivity and ease of use, like the Java 8. This paper tries to demonstrate a declarative language like PROLOG is perfectly suitable to be used to solve even common programming issue, like deciding an element is part of an array or not.

  5. Early declarative memory predicts productive language: A longitudinal study of deferred imitation and communication at 9 and 16months.

    Science.gov (United States)

    Sundqvist, Annette; Nordqvist, Emelie; Koch, Felix-Sebastian; Heimann, Mikael

    2016-11-01

    Deferred imitation (DI) may be regarded as an early declarative-like memory ability shaping the infant's ability to learn about novelties and regularities of the surrounding world. In the current longitudinal study, infants were assessed at 9 and 16months. DI was assessed using five novel objects. Each infant's communicative development was measured by parental questionnaires. The results indicate stability in DI performance and early communicative development between 9 and 16months. The early achievers at 9months were still advanced at 16months. Results also identified a predictive relationship between the infant's gestural development at 9months and the infant's productive and receptive language at 16months. Moreover, the results show that declarative memory, measured with DI, and gestural communication at 9months independently predict productive language at 16months. These findings suggest a connection between the ability to form non-linguistic and linguistic mental representations. These results indicate that the child's DI ability when predominantly preverbal might be regarded as an early domain-general declarative memory ability underlying early productive language development.

    Directory of Open Access Journals (Sweden)

    Erivaldo Pereira do Nascimento

    2012-05-01

    Full Text Available This article aims at describing the semantic argumentative structure of the textual/discursive genre Letter of Declaration, one of the documents with which the executive secretary frequently deals. This investigation is based on the Argumention Theory in the Language proposed by Ducrot (1988,1987. We also used the studies about Discursive Modalization proposed by Koch (2002, Castilho e Castilho (1993, Nascimento (2005, among others. Modalization is considered here as a semantic argumentative strategy, as it enables the speaker to make a statement or to express a point of view about the content of his/her enunciation, according to the interlocution. This study about the previously mentioned gender is qualitative, quantitative and descriptive. The corpus used is composed of 20 (twenty Letters of Declaration issued by different organizations or private and public institutions. We perceived that in the Letters of Declaration analysed argumentation is achieved by the use of modalizers and argumentative operators, used by the speaker to produce different effects of meaning in the texts.

  11. Declarative memory.

    Science.gov (United States)

    Riedel, Wim J; Blokland, Arjan

    2015-01-01

    Declarative Memory consists of memory for events (episodic memory) and facts (semantic memory). Methods to test declarative memory are key in investigating effects of potential cognition-enhancing substances--medicinal drugs or nutrients. A number of cognitive performance tests assessing declarative episodic memory tapping verbal learning, logical memory, pattern recognition memory, and paired associates learning are described. These tests have been used as outcome variables in 34 studies in humans that have been described in the literature in the past 10 years. Also, the use of episodic tests in animal research is discussed also in relation to the drug effects in these tasks. The results show that nutritional supplementation of polyunsaturated fatty acids has been investigated most abundantly and, in a number of cases, but not all, show indications of positive effects on declarative memory, more so in elderly than in young subjects. Studies investigating effects of registered anti-Alzheimer drugs, cholinesterase inhibitors in mild cognitive impairment, show positive and negative effects on declarative memory. Studies mainly carried out in healthy volunteers investigating the effects of acute dopamine stimulation indicate enhanced memory consolidation as manifested specifically by better delayed recall, especially at time points long after learning and more so when drug is administered after learning and if word lists are longer. The animal studies reveal a different picture with respect to the effects of different drugs on memory performance. This suggests that at least for episodic memory tasks, the translational value is rather poor. For the human studies, detailed parameters of the compositions of word lists for declarative memory tests are discussed and it is concluded that tailored adaptations of tests to fit the hypothesis under study, rather than "off-the-shelf" use of existing tests, are recommended.

    The interaction between an object and its environment is examined by methods of environment simulation. With regard to possible synergisms, technical considerations and holistic thinking are essential. Environmental simulation is mainly concerned with questions of ability to function and the service life of technical products in their environment. The environmental simulation is used to discover cause/effect mechanisms in ageing and weathering processes. Questions of artificial ageing and speeded up time tests play a great part here. (orig.)

  14. Charcoal production and environmental degradation

    International Nuclear Information System (INIS)

    Hosier, R.H.

    1993-01-01

    This paper examines the environmental impacts of continued tree harvesting for charcoal production to supply the urban areas in Tanzania. Woodlands appear to recover relatively well following harvesting for charcoal production. Selective harvesting, where the high quality, low cost fuel production species and specimens are culled first from a piece of land, serves to maintain the viability of the woodlands resource while providing charcoal. This recovery period can be prolonged through any number of human induced activities, such as heavy grazing, multiple burns and extended cultivation periods. At the same time, post-harvest management techniques, such as coppice management, sprout protection and fertilization, can also improve the ability of woodlands to recover following harvesting. The environmental history of a given area determines why certain areas continue to be strong suppliers of woodfuel while others are not. For example, Shinyanga started from a low productivity base and has been degraded by successive waves of tree harvesting compounded by heavy grazing pressure. It is this multiple complex of pressures over a long period of time on land which is intrinsically of low productivity, and not the harvesting of woodlands for fuels, which has led to the environmental degradation in these areas.

    the environmental productivity of individual generator units based on a panel data set for the period 1998 to 2011 that includes virtually all fuel-fired generator units in Denmark. We further decompose total productivity into technical efficiency, best practice ratio, and scale efficiency and use a global...... Malmquist index to calculate the yearly changes. By applying time series clustering, we can identify high, middle, and low performance groups of generator units in a dynamic setting. Our results indicate that the sectoral productivity only slightly increased over the fourteen years. Furthermore, we find...... that there is no overall high achiever group, but that the ranking, although time consistent, varies between the different productivity measures. However, we identify steam turbines and combustion engines for combined heat and power production as potential high performers, while combustion engines that only produce...

    Care of the environment is set to be one of the growth industries of the 1990s. Unfortunately, information as to the effect current life styles are having on the environment and, therefore, what remedial action is necessary, varies from the full to the non-existent and, worst of all, from the misleading to the incorrect. For various reasons, some aspects of technology have received greater attention from the media and environmental pressure groups than others. Energy production and conversion technologies, of course, are very much in this category. Indeed, the problem in these areas is not lack of information but a positive surfeit. (author)

    2010-12-01

    During the year 2009, 134 reports of suspected adverse drug reactions (ADRs) to veterinary medicinal products (VMPs) were received (106 in the year 2008). The distribution according to species and drug classes remained in line with previous years. Companion animals were involved in most of the reports (46 % dogs, 19 % cats), followed by cattle or calves (22 %). Antiparasitic drugs made the biggest part with 30 % of the reports, followed by antiinfectives (19 %) and hormones (13 %). Some reactions following their use are specifically discussed. 95 additional enquiries about ADRs of VMPs were received by the Swiss Toxicological Information Centre in Zürich. Most of them concerned dogs or cats and antiparasitics or anti-inflammatory drugs. In the vaccinovigilance program, a total of 1020 reports were received, of which 1000 were related to the vaccination against blue tongue disease. The most frequently reported adverse reactions were aborts, mastitis or alterations of milk quality and they are specifically discussed.

  19. Visualising the environmental appearance of audio products

    Can environmental friendliness be communicated by the design style and appearance of products? (such as form, colour, style or material)? Consumers are interested in buying environmental products and design styles might be used as communicative tools. However, current 'green' products show something else. Environmental aspects are chiefly promoted by marketing programs based on technical items like the use of materials, hazardous substances, energy consumption, etc. By a qualitative and exploratory research the environmental design styles according to consumers' opinions were analysed with larger audio products as case study. Visible distinctive differences can be identified between the most and the least environmental rated products. A 'Green flagship', which claims to be environmentally orientated, wasn't recognised as such by consumers. And women and men perceive environmental friendliness in another way. From this research can be concluded that more attention is needed to visualise the good technical environmental performance of products. (orig.)

  20. Environmental costs of fossil fuel energy production

    Riva, A.; Trebeschi, C.

    1997-01-01

    The costs of environmental impacts caused by fossil fuel energy production are external to the energy economy and normally they are not reflected in energy prices. To determine the environmental costs associated with an energy source a detailed analysis of all environmental impacts of the complete energy cycle is required. The economic evaluation of environmental damages is presented caused by atmospheric emissions produced by fossil fuel combustion for different uses. Considering the emission factors of sulphur oxides, nitrogen oxides, dust and carbon dioxide and the economic evaluation of their environmental damages reported in literature, a range of environmental costs associated with different fossil fuels and technologies is presented. A comparison of environmental costs resulting from atmospheric emissions produced by fossil-fuel combustion for energy production shows that natural gas has a significantly higher environmental value than other fossil fuels.

    2000-12-01

    The principal themes for the Biomedical Research and the Environment Conference Committee on Environmental Economics in Biomedical Research include the following: healthcare delivery companies and biomedical research organizations, both nonprofit and for-profit, need to improve their environmental performance; suppliers of healthcare products will be called upon to support this need; and improving the environmental profile of healthcare products begins in research and development (R&D). The committee report begins with requirements from regulatory authorities (e.g., U.S. Environmental Protection Agency [EPA], the U.S. Food and Drug Administration), and the healthcare delivery sector). The 1998 American Hospital Association and EPA Memorandum of Understanding to reduce solid waste and mercury from healthcare facilities is emblematic of these requirements. The dominant message from the requirements discussion is to ensure that R&D organizations do not ignore customer, environmental, and regulatory requirements in the early stages of product development. Several representatives from healthcare products manufacturers presented their companies' approaches to meeting these requirements. They reported on efforts to ensure that their R&D processes are sensitive to the environmental consequences from manufacturing, distributing, using, and disposing of healthcare products. These reports describe representatives' awareness of requirements and the unique approaches their R&D organizations have taken to meet these requirements. All representatives reported that their R&D organizations have embraced environmental product design because it avoids the potential of returning products to R&D to improve the environmental profile. Additionally, several reports detailed cost savings, sustainability benefits, and improvements in environmental manufacturing or redesign, and increased customer satisfaction. Many companies in healthcare delivery are working to improve environmental

    Primary copper production is a major activity in the mining sector. It is highly energy-intensive, ranking third in specific energy consumption (SEC) among the five major basic metals (aluminum, copper, iron, lead and zinc) and poses important environmental hazards. We examine the large discrepancy between theoretical (from thermodynamics) and actual (from empirical data) SECs and then describe relevant environmental issues, focusing on the most significant energy-related environmental impacts of primary copper production with emphasis on greenhouse-gas (GHG) emissions. An example of GHG energy-related abatement that concurrently improves energy use is presented. (Author)

    The National Oceanic and Atmospheric Administration (NOAA), Department of Defense (DoD), and National Aeronautics and Space Administration (NASA) are jointly acquiring the next-generation weather and environmental satellite system; the National Polar-orbiting Operational Environmental Satellite System (NPOESS). NPOESS replaces the current Polar-orbiting Operational Environmental Satellites (POES) managed by NOAA and the Defense Meteorological Satellite Program (DMSP) managed by the DoD. The NPOESS satellites carry a suite of sensors that collect meteorological, oceanographic, climatological, and solar-geophysical observations of the earth, atmosphere, and space. The ground data processing segment for NPOESS is the Interface Data Processing Segment (IDPS), developed by Raytheon Intelligence and Information Systems. The IDPS processes NPOESS satellite data to provide environmental data products (aka, Environmental Data Records or EDRs) to NOAA and DoD processing centers operated by the United States government. The IDPS will process EDRs beginning with the NPOESS Preparatory Project (NPP) and continuing through the lifetime of the NPOESS system. Northrop Grumman Aerospace Systems Algorithms and Data Products (A&DP) organization is responsible for the algorithms that produce the EDRs, including their quality aspects. Together, IDPS and A&DP must support the calibration, validation, and data quality improvement initiatives of the NPOESS program to ensure the production of atmospheric and environmental products that meet strict requirements for accuracy and precision. In support of this activity, A&DP and IDPS continually updates the estimated performance of the NPOESS system with respect to both latency and data quality, using the latest operational implementation of the data processing software and information from instrument test activities. This presentation will illustrate and describe the processing chains that create the data products, as well as describe the

    Technological change is often seen as the promising device that will mitigate or solve environmental problems. Policy intervention that spurs the development, adoption and diffusion of new, environmentally benign technologies therefore holds great appear for environmental authorities. Policymakers have various instruments at their disposal to affect technological diffusion, ranging from direct regulation (command-and-control strategies) to market-based instruments, such as taxes, subsidies and tradable pollution permits. This paper examines environmental subsidies as a technology diffusion policy. The authors apply evolutionary game theory to explore the relationship between subsidies for clean technology, the diffusion of that technology and the degree of product differentiation in an imperfectly competitive market. They show that the subsidy succeeds in reducing environmental damage only when the substitution effect (the reduction in pollution associated with the clean technology) exceeds the output effect (the extent that the subsidy increases output). When the substitution effect does dominate, environmental damage decreases monotonically during the diffusion process. The extent of diffusion (the degree to which clean technolgy replaces dirty) and the likelihood that the substitution effect will dominate both decrease with the extent of product differentiation. Finally, the subsidy for clean technology will spill over to the remaining dirty producers increasing their profit as well.

    This paper is a preliminary attempt to provide information on the probable environmental effects of energy crop production relative to other potential uses of the land. While dedicated energy crop production is anticipated to occur primarily on land currently in agricultural production, some pastureland and forestland with a high potential for conversion to agricultural production may be utilized. Experimental results suggest that chemical use on energy crops will be lower than on most row crops and that land producing energy crops should experience less erosion than land producing row crops. Long-term site productivity should not be a major issue if macro-and micro-fertilizers are added as needed and nutrient-conserving production techniques are used. (Author)

    The present study assessed the nutrition information displayed on ready-to-eat packaged foods and the nutritional quality of those food products in Thailand. In March 2015, the nutrition information panels and nutrition and health claims on ready-to-eat packaged foods were collected from the biggest store of each of the twelve major retailers, using protocols developed by the International Network for Food and Obesity/Non-communicable Diseases Research, Monitoring and Action Support (INFORMAS). The Thai Nutrient Profile Model was used to classify food products according to their nutritional quality as 'healthier' or 'less healthy'. In total, information from 7205 food products was collected across five broad food categories. Out of those products, 5707 (79·2 %), 2536 (35·2 %) and 1487 (20·6 %) carried a nutrition facts panel, a Guideline Daily Amount (GDA) label and health-related claims, respectively. Only 4691 (65·1 %) and 2484 (34·5 %) of the products that displayed the nutrition facts or a GDA label, respectively, followed the guidelines of the Thai Food and Drug Administration. In total, 4689 products (65·1 %) could be classified according to the Thai Nutrient Profile Model, of which 432 products (9·2 %) were classified as healthier. Moreover, among the 1487 products carrying health-related claims, 1219 (82·0 %) were classified as less healthy. Allowing less healthy food products to carry claims could mislead consumers and result in overconsumption of ready-to-eat food products. The findings suggest effective policies should be implemented to increase the relative availability of healthier ready-to-eat packaged foods, as well as to improve the provision of nutrition information on labels in Thailand.

    2011-07-15

    Cultured meat (i.e., meat produced in vitro using tissue engineering techniques) is being developed as a potentially healthier and more efficient alternative to conventional meat. Life cycle assessment (LCA) research method was used for assessing environmental impacts of large-scale cultured meat production. Cyanobacteria hydrolysate was assumed to be used as the nutrient and energy source for muscle cell growth. The results showed that production of 1000 kg cultured meat requires 26-33 GJ energy, 367-521 m(3) water, 190-230 m(2) land, and emits 1900-2240 kg CO(2)-eq GHG emissions. In comparison to conventionally produced European meat, cultured meat involves approximately 7-45% lower energy use (only poultry has lower energy use), 78-96% lower GHG emissions, 99% lower land use, and 82-96% lower water use depending on the product compared. Despite high uncertainty, it is concluded that the overall environmental impacts of cultured meat production are substantially lower than those of conventionally produced meat.

  9. Environmental protection: Streamlining petroleum exploration and production

    International Nuclear Information System (INIS)

    Hunt, A.M.

    1991-01-01

    The petroleum industry is inherently subject to a tremendous degree of volatility through fluctuation in world market prices and vagaries of world politics. A more recent stressful demand on the existing domestic petroleum exploration and production system has been the burgeoning number of environmental regulations imposed on this segment of the industry. Prudent and acceptable oil-field practices must now include agency-regulated environmental protection measures. Many independent producers are unfamiliar not only with the regulatory agencies, but also with the jargon and ambiguities, of regulations that very widely from state to state. Whereas some companies perceive only the restrictions and added cost of regulatory compliance, other companies have sought to optimize benefits while minimizing financial burdens by approaching this modern necessity more creatively, thereby discovering numerous means to become even more competitive. The domestic oil field of the 1990s will be increasingly affected by environmental regulation and public opinion. A number of companies have taken a proactive position on environmental issues. Industry examples include Louisiana Land and Exploration Company's history of wetlands conservation and Chevron's SMART (Save Money and Reduce Toxics). The future of the quality of life of this nation, and indeed the planet as a whole, lies in our capability to deal concurrently with the issues of a petroleum-based economy while protecting the natural environment that sustains life

  10. Peat 2003. Production, use, environmental impact

    International Nuclear Information System (INIS)

    2004-01-01

    This report discusses the use of peat for energy production and other purposes, laws and other regulations affecting peat production and use, environmental impact, market situation and international statistics regarding peat production. In Sweden, the extraction and use of peat for energy production is regulated by several laws. Harvesting concessions must be approved by the county council. All combustion plants must be reported, or verified by regional or central authorities, depending on the size of the plant. Most important in this process is to verify the maximum emission levels permitted for sulphur, nitrogen oxides, particles, etc. Since 1991, a law on municipal energy planning requires descriptions of environmental consequences. Thus, environmental considerations must govern energy planning. Energy taxation in Sweden was changed in 1993. At present, the sulphur tax on fuel peat amounts to SEK 30 per kg of sulphur. Nitrogen oxides are also subject to a tax of SEK 40 per emitted kg. For peat, energy and environmental taxes total SEK 0.02 per kWh, excluding VAT. Peat harvesting for the production of energy aroused interest in the early 1980s as a consequence of the increased energy prices. In 2003, about 2,628,000 cubic metres of fuel peat were harvested in Sweden. The fuel peat is used mainly for production of hot water in district heating plants. In 2003, the total use of fuel peat amounted to 4,0 TWh. In addition to fuel peat, about 1,825,000 cubic metres of peat litter (mainly for horticultural use) was produced. In 2003, imports amounted to 382,3000 metric tons or 1.3 million cubic metres of peat. Exports amounted to 103,000 metric tons, consisting primarily of peat for horticultural use. The peat market in Sweden is divided into the energy market and the cultivation market. Political decisions regarding combustion taxes have a great impact on the competitive advantages of different fuels. The major competitors to peat are coal, oil, and renewable energy

    The IAEA receives and manages information declared by States, as prescribed by the relevant safeguards agreements, and, together with all other safeguards-relevant information, evaluates it as part of the process supporting safeguards implementation. Within the Division of Information Management (SGIM), the Section for State Declared Information Analysis (ISD) plays a key role in the processing of State declared information - from the transmission of information to the Agency to its ultimate use in the context of the State evaluation process and the drawing of safeguards conclusions. SGIM-ISD handles an increasing variety and volume of these Member State declarations. While the volume of submissions has grown, the submission methods have not kept pace with either the number or the available technology. The paper and supporting presentation will provide an overview of the variety of declarations and transmission methods. The current paradigm and transmission paths between the State authorities and Agency will be evaluated. It will also lay out a future paradigm and desired features of a next generation system. As the Department of Safeguards is currently re-engineering its information technology infrastructure, the future paradigm will be placed within the context of these changes. (author)

    Fragrance ingredients are a frequent cause of allergic contact dermatitis. The EU Cosmetics Directive states that 26 specific fragrance ingredients, known to cause allergic contact dermatitis, must be declared on the ingredient lists of cosmetic products. To investigate frequencies of sensitization to the 26 individual fragrances and evaluate their importance as screening markers of fragrance allergy. This was a retrospective study based on data from the Department of Dermato-Allergology, Copenhagen University Hospital Gentofte. Eczema patients (n = 1508) were patch tested (January 2008 to July 2010) with the 26 fragrance ingredients. Sensitization to the 26 fragrances was identified in 115 (7.6%) subjects. The most frequent allergens were Evernia furfuracea (n = 50), Evernia prunastri (n = 31), and hydroxyisohexyl 3-cyclohexene carboxaldehyde (n = 24). Including fragrance mix I, fragrance mix II and Myroxylon pereirae, 196 (13.0%) had a fragrance allergy. Testing with the 26 fragrances additionally identified 23 subjects who would otherwise have gone undetected. The majority (75.7%) of positive reactions to the 26 fragrances were of clinical relevance. Sensitization to the 26 individual fragrance ingredients was identified in 7.6% of the subjects patch tested. Most reactions were of clinical relevance. Fragrance-allergic subjects would be missed if testing with the individual fragrance ingredients was not performed. © 2011 John Wiley & Sons A/S.

    2017-12-01

    The main objective of this paper is to compare the environmental impact caused by two different types of water boiling processes. The aim was achieved thanks to product life cycle assessment (LCA) conducted for stovetop and electric kettles. A literature review was carried out. A research model was worked out on the basis of data available in literature as well as additional experiments. In order to have a better opportunity to compare LCA results with reviewed literature, eco-indicator 99 assessment method was chosen. The functional unit included production, usage and waste disposal of each product (according to from cradle to grave approach) where the main function is boiling 3360 l of water during 4-year period of time. A very detailed life cycle inventory was carried out. The mass of components was determined with accuracy of three decimal places (0.001 g). The majority of environmental impact is caused by electricity or natural gas consumption during usage stage: 92% in case of the electric and kettle and 99% in case of stovetop one. Assembly stage contributed in 7% and 0.8% respectively. Uncertainty and sensitivity analyses took into consideration various waste scenario patterns as well as demand for transport. Environmental impact turned out to be strongly sensitive to a chosen pattern of energy delivery (electricity mix) which determined final comparison results. Basing on LCA results, some improvements of products were suggested. The boiling time optimization was pointed out for electric kettle's efficiency improvement. Obtained results can be used by manufacturers in order to improve their eco-effectiveness. Moreover, conclusions following the research part can influence the future choices of home appliances users.

    2005-01-01

    The life cycle analysis method was used to determine the environmental impacts associated with the production of an electrochromic (EC) glazing (called ECD). This paper describes the inventory analysis for all the basic materials used during the manufacture of the ECD, i.e. K-Glass, tungsten oxide (WO 3 ), poly-methyl methacrylate (PMMA), propylene carbonate (PC), lithium perchlorate (LiClO 4 ) and acetic silicone sealant. K-Glass, PC and PMMA account for the 98% of the total device mass and the CO 2 emissions during their production processes are 810 g. The total embodied energy was estimated to be 49 MJ/ECD, with 32.1 MJ/unit of them derived from the K-Glass. The comparison of the total embodied energies of the ECD and various insulating glass units concluded that mass-produced EC glazings could easily compete with them in terms of environmental performance, anticipating cost attenuation and overall thermal and optical behavior. The above analysis could be implemented for the reduction of the embodied energy of the ECD life cycle, since it is proposed as an energy saving device. (Author)

    Kucharska, Małgorzata; Wesołowski, Wiktor; Czerczak, Sławomir; Soćko, Renata

    Electronic cigarettes are currently in common use. However, in Poland there is no specific legislation governing the sale of these products. At the same time, no information has been made public about the hazards e-cigarettes pose to the users and bystanders - passive smokers. The aim of the study was to determine the qualitative composition of the analyzed liquid, which is an essential element of regulating the distribution of such cigarettes. Under this study the method for determining the composition of e-cigarette liquids was developed. This method employs gas chromatography with mass spectrometry (GC-MS). Levels of nicotine and flavoring components were determined in 50 e-liquid samples. The results were compared with the information provided by the manufacturer on the packaging. The applied method of qualitative determination helped to identify the main ingredients, such as nicotine and propylene glycol (PG). Propylene glycol was found to be present in all liquids, because it was used as the solvent for nicotine and flavors. There was a good agreement between the declared and the determined content of nicotine in the analyzed samples. The agreement was considerably poorer for the remaining e-liquid ingredients, mainly flavors. There was no agreement between the flavor substances specified by the manufacturer and aroma identified in the e-cigarette liquid, which may pose a risk to users of e-cigarettes, particularly those susceptible to allergies. Several unsaturated aliphatic alcohols and aldehydes found to be present in the liquids, unstable at elevated temperatures, may be more harmful to the smoker than the original compounds. Therefore, it is essential to implement in Poland the legal provisions regarding e-cigarettes. Med Pr 2016;67(2):239-253.

    If the last year and a half are any indication it would appear that the early 1990's will be to international trade what the early 1980's were to entrepreneurship. Embraced by the popular and business press and encouraged by the administration, exporting has become one of the most talked about topics in business today. As manufacturers, consultants and service providers we are continually told that to survive in the world marketplace we must think globally and compete aggressively. There can be no doubt that export markets, always an interesting sector of business, have become both more important and exciting in recent years. On January 1, 1993 the unified common market of the European Community will officially open for business. Although most of the significant changes in that market have already taken place or been agreed upon, this historic event - creating the single largest market among industrial nations - will undoubtedly have an effect on how we as exporters do business in Europe. The Free Trade Agreement with Canada has been in effect for over two years now and there have been and will continue to be many benefits for us. In developing and newly capitalist countries we can point to Czechoslovakia and Hungary as the first of several potentially lucrative markets. Mexico, in the spotlight due to the new Free Trade initiative, will be a strong new export market in our own backyard. And finally the so called mini-dragons of Southeast Asia cannot be ignored. Whether or not they choose to create a formal trading bloc, their ever increasing foreign reserves should be looked at with hungry, but cautious eyes. In this paper the author identifies a large and ever increasing world of customers beyond our national borders and identifies how those companies and individuals in the environmental products market can benefit greatly

  7. The regional environmental impact of biomass production

    International Nuclear Information System (INIS)

    Graham, R.L.

    1994-01-01

    The objective of this paper is to present a broad overview of the potential environmental impacts of biomass energy from energy crops. The subject is complex because the environmental impact of using biomass for energy must be considered in the context of alternative energy options while the environmental impact of producing biomass from energy crops must be considered in the context of the alternative land-uses. Using biomass-derived energy can reduce greenhouse gas emissions or increase them; growing biomass energy crops can enhance soil fertility or degrade it. Without knowing the context of the biomass energy, one can say little about its specific environmental impacts. The primary focus of this paper is an evaluation of the environmental impacts of growing energy crops. I present an approach for quantitatively evaluating the potential environmental impact of growing energy crops at a regional scale that accounts for the environmental and economic context of the crops. However, to set the stage for this discussion, I begin by comparing the environmental advantages and disadvantages of biomass-derived energy relative to other energy alternatives such as coal, hydropower, nuclear power, oil/gasoline, natural gas and photovoltaics

    Full Text Available Discrepancies between the Bill nº4148 / 2008 and Principle 10, which has about the commitment of States to ensure access to environmental information, generate the need for reflection on the actual Brazilian paradigms front of such a commitment, as well as sustainability Informational as a prerequisite to the realization of rights. Thus, the objective is to generally examine the relevant provisions to Principle 10, the prospects of the Declaration on Principle 10 in Latin America and the Caribbean and investigate the fundamentals of Bill No. 4148/2008, from the perspective of informational sustainability . After it is intended specifically delineate the contrasts between international goals and the said bill. It seeks to answer the question: The reasons which led the Law No. Project. 4148/2008 to the National Congress and its approval in the Chamber of Deputies, can be considered as opposed to the international commitments made by Brazil, with regard to sustainable environmental information, consolidating in a legal setback? The methodology has as basis of theory and approach to systemic-complex perspective. Procedures are bibliographical and documentary research. The technique is building fichamentos and summaries. Conclusively, one sees that Brazil has adopted contradictory paradigms for the right to environmental information, which need to be better delineated, otherwise these setbacks consubstanciarem in legal setback.

    Silalertruksa, Thapat; Gheewala, Shabbir H.

    2012-01-01

    The study assesses the environmental sustainability of palm biodiesel production systems in Thailand by focusing on their energy efficiency and environmental impact potentials. The Net Energy Balance (NEB) and Renewability indicate energy gain for palm biodiesel and its co-products as compared to fossil energy inputs. In addition, life cycle assessment also reveals lower values of environmental impact potentials of biodiesel as compared to conventional diesel. For example, palm biodiesel can provide greenhouse gas (GHG) reduction of around 46–73% as compared to diesel. Nitrogen-fertilizer production and application in the plantation and the air emissions from the ponds treating palm oil mill effluent (POME) are found to be the major environmental aspects. However, the energy and environmental performances depend on various factors such as the management efficiency of empty fruit bunches (EFB) and POME and the possible land-use change in the future. Recommendations are made for improving environmental performance of palm biodiesel and for securing the long-term availability of crude palm oil supply with a view towards sustainable palm biodiesel production. -- Highlights: ► Environmental sustainability of palm biodiesel production in Thailand is assessed. ► Palm biodiesel can provide GHG reduction of around 46–73% as compared to diesel. ► Net energy ratio and renewability of palm biodiesel both range between 2 and 4. ► Efficient use of by-products in the value chain enhances environmental benefits.

    More than 100 young people from 56 countries voiced their needs and concerns in a Youth Consultation held just before the International Conference on Population and Development (ICPD), August 31 to September 4, 1994. Many journalists from the international press followed the consultation and interviewed the youths, with a short film even produced on the proceedings. After discussing the main topics of the ICPD, participants produced a Youth Declaration with recommendations for action and conclusions for partnership. More than 20 participants remained in Cairo to present consultation conclusions in well-attended workshops and role play at the ICPD NGO Forum. One representative presented the Youth Declaration in ICPD plenary session. These young men and women from all regions of the world, from a diversity of cultural, religious, and political backgrounds found common ground on the need for population concerns to be explicitly and consistently integrated with development in the context of a just and equitable international economic system; a strong focus upon youth education and mobilization in the areas of adolescent health, sexual and reproductive health, the environment, human rights, and political and economic systems; and the sense that now is the time to act at the individual, organizational, national, and national levels. Education and safe sexual behavior do not encourage promiscuity. On the contrary, they promote and enhance healthy, responsible relationships, minimizing the incidence of unplanned pregnancies and sexually transmitted infections when sex does take place. Participants recommend promoting peer education; involving and educating peers through artistic activities such as music and drama; implementing peer counseling and raising awareness through one-on-one interaction, group discussions, printed media, and radio programs; organizing services for youths in a variety of settings; creating jobs for youths in cooperatives and businesses; educating

  16. Making environmental assessments of biomass production systems comparable worldwide

    International Nuclear Information System (INIS)

    Meyer, Markus A; Seppelt, Ralf; Priess, Joerg A; Witing, Felix

    2016-01-01

    Global demand for agricultural and forestry products fundamentally affects regional land-use change associated with environmental impacts (EIs) such as erosion. In contrast to aggregated global metrics such as greenhouse gas (GHG) balances, local/regional EIs of different agricultural and forestry production regions need methods which enable worldwide EI comparisons. The key aspect is to control environmental heterogeneity to reveal man-made differences of EIs between production regions. Environmental heterogeneity is the variation in biotic and abiotic environmental conditions. In the present study, we used three approaches to control environmental heterogeneity: (i) environmental stratification, (ii) potential natural vegetation (PNV), and (iii) regional environmental thresholds to compare EIs of solid biomass production. We compared production regions of managed forests and plantation forests in subtropical (Satilla watershed, Southeastern US), tropical (Rufiji basin, Tanzania), and temperate (Mulde watershed, Central Germany) climates. All approaches supported the comparison of the EIs of different land-use classes between and within production regions. They also standardized the different EIs for a comparison between the EI categories. The EIs for different land-use classes within a production region decreased with increasing degree of naturalness (forest, plantation forestry, and cropland). PNV was the most reliable approach, but lacked feasibility and relevance. The PNV approach explicitly included most of the factors that drive environmental heterogeneity in contrast to the stratification and threshold approaches. The stratification approach allows consistent global application due to available data. Regional environmental thresholds only included arbitrarily selected aspects of environmental heterogeneity; they are only available for few EIs. Especially, the PNV and stratification approaches are options to compare regional EIs of biomass or crop production

  3. Strategic environmental assessment for energy production

    International Nuclear Information System (INIS)

    Jay, Stephen

    2010-01-01

    Amongst the approaches that have developed to improve environmental protection within the energy sector, strategic environmental assessment (SEA) has received relatively little attention. This is despite its potential to overcome some of the shortcomings associated with project-level assessment by intervening at higher levels of energy system planning. In this article, a review is presented of the extent to which SEA has been adopted and otherwise promoted in strategic energy planning processes in a wide range of countries throughout the world (with an emphasis on European Union nations). In this regard, the growing importance of regulatory compliance is underlined, especially within the EU, with a particular focus upon the application of SEA to grid systems. The case of the Belgian transmission system is described, illustrating a proactive approach to SEA. But the difficulties inherent in introducing SEA to an increasingly fragmented and liberalised sector are also drawn out, leading to suggestions by which these difficulties may be addressed.

Three corn conversion processes that could be used to attain the desired 1980 to 1981 production are identified; fermentation plants that use a feedstock of starch and wastes from an adjacent corn refining plants are found to have environmental and economic advantages. No insurmountable environmental problems can be achieved using current technology; the capital and operating costs of this control are estimated. If ethanol production is increased substantially after 1981, the environmentally acceptable use or disposal of stillage, a liquid by-product of fermentation, could become a serious problem.

  9. Voluntary Tools Of The Environmental Oriented Product Policy

    Full Text Available Environmentally oriented product policy is in general determined by the relationships between its aims – subjects – objects - tools. It is based on the integrated approach to the product life cycle, which anticipates an enormous amount of information. It has to solve the questions of the international trade as well as the rules of the International Trade Organization. New forms of preventive environmental strategies and especially Green Marketing are being introduced helping to solve environmental problems and environmental motivation of producers. Many producers face great attention of the public regarding their approach to the environment. Despite the fact that the customers buy products fairly prudently and their behaviour is markedly affected by prices, a particular part of the population prefers the products that do not burden the environment. This brings about a situation, in which the producers within their mutual competition and in relation to customers are enforced to behave responsibly.

    The orientation of the environmental problem in sustainable terms, especially in the industrialized economies, a new profile in the last years has found. In these economies, the search of a clean production franked by a coherent politics of products and the contribution of the design of products, it have given to the environmental speech a new dimension. With the present text it is sought to respond to the necessity of exploring in Colombia this topic that has a decisive paper inside the instruments of protection of the environment cooperating to improve the quality of life in other latitudes. At the moment the theoretical foundations around the development of products play a important role in the different lines of applied investigation carried out by these countries, especially in the mark of a politics of sustainable development. In spite of the importance of this factor in the industrialized countries where the capacity of integration of a coordinated administration is of great meaning, in Colombia, particularly, the relationship between development and design of products with industry, investigation and political of development and, for our case with a clean production, it is characterized by the scarce insert and attention of this discipline

    Agriculture is a profession, which is open to natural conditions and intense human activity. This has brought it in direct interface with the environment. The activities related to agriculture can have favorable as well as unfavorable influence on environment. Pressure of burgeoning population is demanding increased production from agriculture to feed and clothe the teeming millions. This has resulted in excessive use of soil, fertilizers and pesticides. This paper describe the effect of these productive resources on environment and human health. Agriculture is a complex phenomenon. It is open both on natural conditions and to intense human activity. Cyclones, floods, hailstorm, cold, heat and heavy rains all affect agriculture and so do the man-made activities especially those related to expanding industrial production. This has brought agriculture in direct interface with the environment. Agriculture exerts both favorable and unfavorable consequences on environment. The plants absorb carbon dioxide and act as filters to purify polluting aerial substances. Growing of crops itself brings pleasant changes in microclimate and to aesthetics. On the other hand, effluents of all kinds; sewage, industrial, farmyard, domestics are dumped onto the soil surface, which pollute water bodies and affect crop quality. Agricultural chemicals used to increase production can get into air, soil and water and pose serious threat to environment. In Pakistan, agriculture is the mainstay of national economy. It is accorded second priority after defense. Its share in Gross Domestic Product (GDP) is 24%, it contributes by 35% to export earnings, employs 51% of the labour force and provides livelihood to 70% of rural population. Increased pressure of burgeoning population is, however, demanding more output from agriculture to feed and clothe the teeming millions. The productive resources on the other hand are limited and are rapidly shrinking. This has led to excessive use of soil

    2012-01-01

    In the present study, Life Cycle Assessment (LCA) methodology was applied to evaluate the energy consumption and environmental burdens associated with the production of protected crops in an agricultural district in the Mediterranean region. In this study, LCA was used as a 'support tool', to address local policies for sustainable production and consumption patterns, and to create a 'knowledge base' for environmental assessment of an extended agricultural production area. The proposed approach combines organisation-specific tools, such as Environmental Management Systems and Environmental Product Declarations, with the environmental management of the district. Questionnaires were distributed to producers to determine the life cycle of different protected crops (tomatoes, cherry tomatoes, peppers, melons and zucchinis), and obtain information on greenhouse usage (e.g. tunnel vs. pavilion). Ecoprofiles of products in the district were also estimated, to identify supply chain elements with the highest impact in terms of global energy requirements, greenhouse gas emissions, eutrophication, water consumption and waste production. These results of this study enable selection of the 'best practices' and ecodesign solutions, to reduce the environmental impact of these products. Finally, sensitivity analysis of key LCA issues was performed, to assess the variability associated with different parameters: vegetable production; water usage; fertiliser and pesticide usage; shared greenhouse use; substitution of plastics coverings; and waste recycling.

  16. Cleaner production - a tool for sustainable environmental development

    International Nuclear Information System (INIS)

    Ahmad, I.; Batool, S.

    2005-01-01

    Industrial Development and Production with no regard for environmental impacts creates water and air pollution, soil degradation, and large-scale global impacts such as acid rain, global warming and ozone depletion. To create more sustainable methods of industrial production, there needs to be a shift in attitudes away from control towards pollution prevention and management. Cleaner Production (CP) refers to a management process that seeks out and eliminates the causes of pollution, waste generation and resource consumption at their source through input reductions or substitutions, pollution prevention, internal recycling and more efficient production technology and processes for sustainable environmental development. The objective of cleaner production is to avoid generating pollution in the first place, which frequently cuts costs, reduces risks associated with liability, and identifies new market opportunities. Introducing cleaner production has become a goal to improve the competitiveness through increased eco-efficiency. CP is a business strategy for enhancing productivity and environmental performance for overall socio-economic development. The environmental and economic benefits can only be achieved by implementing cleaner production tools. The CP assessment methodology is used to systematically identify and evaluate the waste minimization opportunities and facilitate their implementation in industries. It refers to how goods and services are produced with the minimum environmental impact under present technological and economic limits. CP shares characteristics with many environmental management tools such as Environmental Assessment or Design for Environment by including them among the technological options for reducing material and energy intensiveness in production, as well as facilitating ruse trough remanufacturing and recycling. It is thus an extension of the total quality management process. The CP program has been successfully implemented in

    Due to the diversification efforts of energy sources, use of natural gas that was newly introduced into Turkish economy, has been growing rapidly. Turkey has large reserves of coal, particularly of lignite. The proven lignite reserves are 8.0 billion tons. The estimated total possible reserves are 30 billion tons. Turkey, with its young population and growing energy demand per person, its fast growing urbanization, and its economic development, has been one of the fast growing power markets of the world for the last two decades. It is expected that the demand for electric energy in Turkey will be 580 billion kWh by the year 2020. Turkey's electric energy demand is growing about 6-8% yearly due to fast economic growing. This paper deals with energy demand and consumption for environmental issues in Turkey.

    Full text: The Director General of the International Atomic Energy Agency, Mohamed ElBaradei, announced that the IAEA received this evening, Sunday, 8 December 2002, at its Headquarters in Vienna, an approximately 2400 page declaration on Iraq's nuclear programme. The declaration consists of about 2100 pages in English and 300 pages in Arabic. The declaration was submitted by the Government of Iraq in response to paragraph 3 of Security Council resolution 1441 (8 November 2002), which requires Iraq to provide to UNMOVIC, the IAEA and to the Security Council, not later than 30 days of the date of that resolution, with 'currently accurate, full, and complete declaration of all aspects of its programmes to develop chemical, biological, and nuclear weapons, ballistic missiles, and other delivery systems... as well as all other chemical, biological, and nuclear programmes, including any which it claims are for purposes not related to weapon production or material'. 'The IAEA will immediately begin to assess this important new document,' said Mr. ElBaradei, 'including the painstaking and systematic cross-checking of the information provided by Iraq against information which the IAEA already has, information that it expects to receive from other Member States, as contemplated in resolution 1441, and results of past and present Agency verification activities.' Complete assessment of the declaration will be time consuming, particularly in light of the need to translate the 300 pages of Arabic text into English. However, the IAEA expects to be able to provide a preliminary analysis of the document to the Security Council within the next ten days, with a fuller assessment to be provided when it reports to the Council at the end of January.

  19. Making Rice Production More Environmentally-Friendly

    2016-05-01

    Full Text Available Irrigated rice production is one of the most essential agricultural activities for sustaining our global population, and at the same time, one of the agricultural sectors considered most eco-unfriendly. This is because it consumes a larger share of available freshwater resources, competing with varied ecosystems as well as other economic sectors; its paddy fields are responsible for significant emission of greenhouse gases; and the reliance on chemical fertilizers and various agrochemicals contributes to pollution of soils and water systems. These stresses on soils, hydrology and atmosphere are actually not necessary for rice production, which can be increased by modifying agronomic practices though more agroecologically-sound management practices. These, combined under the rubric of the System of Rice Intensification (SRI, can reduce requirements of irrigation water, chemical fertilizer and agrochemicals while increasing paddy yields and farmer’s net incomes. Here we discuss how irrigated rice production can be made more eco-friendly for the benefit of farmers, consumers and the environment. This is achieved by introducing practices that improve the growth and functioning of rice plants’ root systems and enhance the abundance, diversity and activity of beneficial soil organisms that live around plant roots and within the plants themselves as symbiotic endophytes.

    2016-04-01

    Full Text Available Environmental legislation is increasingly changing its focus from manufacturing-oriented to product-oriented instruments. Compliance with product-related environmental legislation is achieved by the incorporation of environmental requirements into the early phases of the product development process (PDP. Nevertheless, the deployment of product-related environmental legislation into product requirements is still a challenge. This study followed an inductive approach to propose a guideline to support the identification, analysis and deployment of product requirements based on product-related environmental legislation. The guideline is composed of nine steps, clustered into three groups according to their main objective: (A identification of environmental product-related legislation; (B identification of legislative topics to be considered for the deployment of requirements; and (C creation and validation of product requirements. The product requirements deployed are to be considered during the PDP. The guideline was evaluated in an expert consultation in a large manufacturing company, suggesting that it can be used to support the systematization and deployment of product-related environmental requirements.

    This report presents the preliminary findings from the first phase of the environmental survey of the United States Department of Energy (DOE) Feed Materials Production Center (FMPC), conducted June 16 through 27, 1986. The survey is being conducted by an interdisciplinary team of environmental specialists, led and managed by the Office of Environment, Safety and Health's Office of Environmental Audit. Individual team components are being supplied by a private contractor. The objective of the survey is to identify environmental problems and areas of environmental risk associated with the FMPC. The survey covers all environmental media and all areas of environmental regulation. It is being performed in accordance with the DOE Environmental Survey Manual. This phase of the survey involves the review of existing site environmental data, observations of the operations carried on at FMPC, and interviews with site personnel. The survey team developed a Sampling and Analysis Plan to assist in further assessing certain of the environmental problems identified during its onsite activities. The Sampling and Analysis Plan will be executed by a DOE national laboratory or a support contractor. When completed, the results will be incorporated into the FMPC Environmental Survey Interim Report. The Interim Report will reflect the final determinations of the FMPC survey. 41 refs., 20 figs., 25 tabs.

    Wojtanowicz, A.K.

    1997-01-01

    Environmental control technology (ECT) is process integrated and relates mainly to pollution prevention and risk assessment. Mechanisms of environmental impact in petroleum drilling, well completion and production, include the generation of waste, induction of toxicity or the creation of pathways for pollutant migration. The identification and evaluation of these mechanisms constitute two parts of the scope of ECT. A third part is the development of new techniques to comply with environmental requirements without prejudicing productivity. The basic concepts of the ECT approach are presented in this chapter. The approach is then used to analyse oilfield drilling and production processes. Environmental control components developed in these technologies are described. These include: the control of the volume and toxicity of drilling fluids; source separation technology in produced water cleaning; subsurface injection of oilfield waste slurries; containment technology in the integrity of petroleum wells; subsurface reduction of produced water; oilfield pit closure technology.

    2011-09-01

    Full Text Available How to design a production process with low carbon emissions and low environmental impact as well as high manufacturing performance is a key factor in the success of low-carbon production. It is important to address concerns about climate change for the large carbon emission source manufacturing industries because of their high energy consumption and environmental impact during the manufacturing stage of the production life cycle. In this paper, methodology for determining a production process is developed. This methodology integrates process determination from three different levels: new production processing, selected production processing and batch production processing. This approach is taken within a manufacturing enterprise based on prior research. The methodology is aimed at providing decision support for implementing Environmentally Benign Manufacturing (EBM and low-carbon production to improve the environmental performance of the manufacturing industry. At the first level, a decision-making model for new production processes based on the Genetic Simulated Annealing Algorithm (GSAA is presented. The decision-making model considers not only the traditional factors, such as time, quality and cost, but also energy and resource consumption and environmental impact, which are different from the traditional methods. At the second level, a methodology is developed based on an IPO (Input-Process-Output model that integrates assessments of resource consumption and environmental impact in terms of a materials balance principle for batch production processes. At the third level, based on the above two levels, a method for determining production processes that focus on low-carbon production is developed based on case-based reasoning, expert systems and feature technology for designing the process flow of a new component. Through the above three levels, a method for determining the production process to identify, quantify, assess, and optimize the

    Overall, our results confirm that wild algal species sequester a wide range of organic and metal contaminants and excess nutrients (PAHs, trace metals, and nutrients) from natural waters, and suggest parameters that could be useful in predicting uptake rates for algae growing on an algal floway or other algal growth systems in the environment or in industrial processes. The implication for various fuel production processes differ with the detailed unit operations involved, and these results will be of use in the developing of scaling experiments for various types of engineering process designs.

    Cyanobacteria are capable of thriving in almost all environments. Recent changes in climatic conditions due to increased human activities favor the occurrence and severity of harmful cyanobacterial bloom all over the world. Knowledge of the regulation of cyanotoxins by the various environmental factors is essential for effective management of toxic cyanobacterial bloom. In recent years, progress in the field of molecular mechanisms involved in cyanotoxin production has paved the way for assessing the role of various factors on the cyanotoxin production. In this review, we present an overview of the influence of various environmental factors on the production of major group of cyanotoxins, including microcystins, nodularin, cylindrospermopsin, anatoxins and saxitoxins.

    Lorenzetti, Romina; Costantini, Edoardo A. C.; Malorgio, Giulio

    2015-04-01

    Vitivinicultural "terroir" is a concept referring to an area in which the collective knowledge of the interactions between environment and vitivinicultural practices develops, providing distinctive characteristics to the products. The effect of the environment components over the terroir has been already widely demonstrated. What it has not been studied yet is their possible effect on the structure of wine production. Therefore, the aim of this work was to find if environmental drivers influence the wine production structure. This kind of investigation necessarily involves a change of scale towards wide territories. We used the Italian Denomination of Origin territories, which were grouped in Macro-areas (reference scale 1:500,000) with respect of geographic proximity, environmental features, viticultural affinity and tradition. The characterization of the structure of the wine transformation industry was based on the official data reported in the wine production declarations related to the year 2008. Statistics were taken into account about general quantitative variables of wine farms, presence of associative forms, degree of vertical integration of wineries, quality orientation of wine producers, and acreage of vineyard. The environmental variables climate, soil, and vegetation vigour were selected for their direct influence on the vine growing. A second set of variables was chosen to express the effect of land morphology on viticultural management. The third one was intended to discover the possible relationships between viticultural structures and land quality, such as the indexes of sensitivity to desertification, the soil resistance to water erosion, and land vulnerability. A PCA was carried out separately for the environmental and economic data to reduce the database dimensions. The new economic and environmental synthetic descriptors were involved in three multivariate analyses: i) the correlation between economic and environmental descriptors through the

    1980-06-01

    The Energy Policy and Conservation Act of 1975 requires DOE to prescribe energy efficiency standards for 13 consumer products. The Consumer Products Efficiency Standards (CPES) program covers: refrigerators and refrigerator-freezers, freezers, clothes dryers, water heaters, room air conditioners, home heating equipment, kitchen ranges and ovens, central air conditioners (cooling and heat pumps), furnaces, dishwashers, television sets, clothes washers, and humidifiers and dehumidifiers. This Environmental Assessment evaluates the potential environmental and socioeconomic impacts expected as a result of setting efficiency standards for all of the consumer products covered by the CPES program. DOE has proposed standards for eight of the products covered by the Program in a Notice of Proposed Rulemaking (NOPR). DOE expects to propose standards for home heating equipment, central air conditioners (heat pumps only), dishwashers, television sets, clothes washers, and humidifiers and dehumidifiers in 1981. No significant adverse environmental or socioeconomic impacts have been found to result from instituting the CPES.

    Environmental pressures from European consumption and production shows how economic and environmental data can be integrated to analyse environmental performance and material efficiency of whole economies as well as their individual elements. The analyses presented in the report provide policy makers with a tool to target economic incentives and information campaigns, encouraging a shift to more sustainable production and consumption patterns in order to reduce Europe's global footprint. The report discusses two analytical approaches. The production-based method considers direct environmental pressures caused by European industries and service providers - for example, the extraction of material resources by the mining and quarrying sector, air pollutants from power stations, greenhouse gas emissions from agriculture and so on. The consumption-based method focuses on the indirect environmental pressures caused by European consumers. In this approach, the direct production-related pressures are attributed to broad groups of products and services, also taking into account pressures that are embodied in goods imported into the EU. Using Environmentally Extended Input Output Analysis (EE-IOA) it is possible to estimate the environmental pressures ultimately generated by individual product groups and also by European consumption as a whole. Four types of environmental pressures are considered by the report: raw material use, greenhouse gas emissions, acidifying air emissions, and air pollutants leading to harmful ground-level ozone. However, the method has the potential to assess many other types of environmental pressure including land use, water use, waste generation and energy use. Thanks to the conceptual consistency between the system of national economic accounts and environmental accounts, data on environmental pressures is directly comparable to economic expenditure. Policy makers can thus see which sectors have been most successful in decoupling

    With the support of the US Agency for International Development, the National Rural Electric Cooperative Association (NRECA) is assisting their utility counterparts in Bolivia to improve electric service in the country`s rural population. In remote areas, the cost of extending transmission lines to small communities is prohibitive, and diesel generators represent an expensive alternative, especially for baseload power. This has led to serious consideration of electric generating systems using locally available renewable resources, including biomass, hydro, wind, and solar energy. A project has recently been initiated in Riberalta, in the Amazonian region of Bolivia, to convert waste Brazil nut shells and sawmill residues to electricity. Working in tandem with diesel generators, the biomass-fired plant will produce base-load power in an integrated system that will be able to provide reliable and affordable electricity to the city. The project will allow the local rural electric cooperative to lower the price of electricity by nearly forty percent, enable the local Brazil nut industry to increase its level of mechanization, and reduce the environmental impacts of dumping waste shells around the city and in an adjacent river. The project is representative of others that will be funded in the future by NRECA/AID.

    On-farm production of hay and high-protein-content feed has several advantages such as diversification of on-farm cultivated crops, reduction of off-farm feed concentrates transported over long distances and a reduction in runoff during the winter season if grown crops are perennial. Among those crops cultivated for high-protein-content feed, alfalfa (Medicago sativa L.) is one of the most important in the Italian context. Nevertheless, up to now, only a few studies have assessed the environmental performance of alfalfa hay production. In this study, using the Life Cycle Assessment approach, the environmental impact of alfalfa hay production in Northern Italy was analyzed. More in detail, two production practices (without and with irrigation) were compared. The results show that alfalfa hay production in irrigated fields has a better environmental performance compared to non-irrigated production, mainly because of the yield increase achieved with irrigation. In particular, for the Climate Change impact category, the impact is equal to 84.54 and 80.21kgCO 2 /t of hay for the scenario without and with irrigation, respectively. However, for two impact categories (Ozone Depletion and Human Toxicity-No Cancer Effect), the impact of irrigation completely offsets the yield increase, and the cultivation practice without irrigation shows the best environmental performance. For both scenarios, the mechanization of harvest is the main environmental hotspot, mostly due to fuel consumption and related combustion emissions. Wide differences were highlighted by comparing the two scenarios with the Ecoinvent process of alfalfa hay production; these differences are mostly due to the cultivation practice and, in particular, to the more intensive fertilization in Swiss production.

    As the production of biofuels continues to expand worldwide, criticism about, e.g. the energy output versus input and the competition with food has been questioned. However, biofuels may be optimized to increase the environmental performance through the concepts of industrial symbiosis. This paper offers a quantification of the environmental performance of industrial symbiosis in the biofuel industry through integration of biogas and ethanol processes using a life cycle approach. Results show that although increasing integration is assumed to produce environmental benefits in industrial symbiosis, not all impact categories have achieved this and the results depend upon the allocation methods chosen

    Bio-ethanol is playing an important role in renewable energy for transport according to Thai government policy. This study aims to evaluate the energy efficiency and renewability of bio-ethanol system and identify the current significant environmental risks and availability of feedstocks in Thailand. Four of the seven existing ethanol plants contributing 53% of the total ethanol fuel production in Thailand have been assessed by the net energy balance method and Life Cycle Assessment (LCA). A renewability and net energy ratio portfolio has been used to indicate whether existing bio-ethanol production systems have net energy gain and could help reduce dependency on fossil energy. In addition, LCA has been conducted to identify and evaluate the environmental hotspots of 'cradle to gate' bio-ethanol production. The results show that there are significant differences of energy and environmental performance among the four existing production systems even for the same feedstock. The differences are dependent on many factors such as farming practices, feedstock transportion, fuel used in ethanol plants, operation practices and technology of ethanol conversion and waste management practices. Recommendations for improving the overall energy and environmental performance of the bio-ethanol system are suggested in order to direct the bio-ethanol industry in Thailand towards environmental sustainability.

  8. How can we improve the environmental sustainability of poultry production?

    2016-08-01

    The review presents results of recent life cycle assessment studies aiming to quantify and improve the environmental performance of UK poultry production systems, including broiler meat, egg and turkey meat production. Although poultry production has been found to be relatively environmentally friendly compared with the production of other livestock commodities, it still contributes to environmental impacts, such as global warming, eutrophication and acidification. Amongst different sub-processes, feed production and transport contributes about 70 % to the global warming potential of poultry systems, whereas manure management contributes about 40-60 % to their eutrophication potential and acidification potential, respectively. All these impacts can be reduced by improving the feed efficiency, either by changing the birds through genetic selection or by making the feed more digestible (e.g. by using additives such as enzymes). However, although genetic selection has the potential to reduce the resources needed for broiler production (including feed consumption), the changing need of certain feed ingredients, most notably protein sources as a result of changes in bird requirements may limit the benefits of this strategy. The use of alternative feed ingredients, such as locally grown protein crops and agricultural by-products, as a replacement of South American grown soya, can potentially also lead to improvements in several environmental impact categories, as long as such feeding strategies have no negative effect on bird performance. Other management options, such as improving poultry housing and new strategies for manure management have also the potential to further improve the environmental sustainability of the poultry industries in Europe.

    The cosmetic industry's growing concern about the impact of its supply chain on the environment, sustainability of raw materials, and biodiversity increases the need to ensure that the final product has a lower environmental impact. The objective of this review is to summarize and compare the information available from international organizations and legislation regarding the main criteria used to assess raw materials for aquatic toxicity, as well as the most suitable alternative methods for obtaining assessment parameters. Using the literature available in databases, a review of the scientific literature and international legislation, this work discusses and compares the parameters established by international organizations such as the Environmental Protection Agency (EPA) and Cradle to Cradle (C2C), as well as European legislation, namely, European Regulation 1272/2008, for assessing environmental impact. Defining the ecotoxicity parameters of the main classes of raw materials in rinse-off cosmetic products can enable the development of products that are more environmentally sustainable, prioritizing substances with less environmental impact.

    Full Text Available The basis of life of any society is a safe environment that is not only the guarantee of welfare and quality of life, but also the guarantee of the further development of human civilization. That is why in the modern world the issue of the preservation of the natural environment is of special actuality. The gradual awareness by humanity of new threats (high degree of concentration of harmful industries; high level of resource and energy consumption; lack of modern environmental technologies; slow but inevitable degradation of the gene pool of a population due to the consumption of poor quality and in most cases harmful products, etc. forced the society to seek new approaches to socio-economic development and environmental management. One of such approaches is the introduction of ecological and organic labeling. Marking is a source of information about the purity, safety and quality of the products offered in the market; effective information mechanism, which is a kind of quality mark for the offered products. The current practice of ecological and organic labeling aimed at the increase of level consumer's awareness and the changing models of purchasing behavior in the direction of environmental protection. The feature of most marking systems of environmentally friendly and safe products is the obligation of compliance with the established requirements used by producers of raw materials and technologies taking into account their potential environmental impact. Labeling of ecologically clean and safe products is reducing the negative impact on the environment and on the human's health. It is the consequence of changes in the economic environment, namely: the improvement of socio-ethical requirements to production; the increasing level of integration of producers and service providers; the customer's satisfaction in varieties of products; globalization of economic space; reduction of time for development, standardization and production. Labeling is

    Biodiesel as renewable, environmental friendly, less toxic, and biodegradable is an attractive alternative to fossil fuels and is produced mainly from vegetable oils and animal fats. It is expected, globally, that the use of renewable biofuels, in general, will increase rapidly in the near future. The growing biodiesel production and usage have encouraged assessment of its impact on the environment. The present paper reviews various aspects of biodiesel production using commercial processing technology and biodiesel use through evaluation and analysis of the studies concerning environmental impacts of biodiesel. As a general conclusion, it can be said that biodiesel has the potential to offer a series of perceived benefits such as political, economical, and agricultural, as well as environmental (due to its biodegradability, less toxicity, renewability) and health (greenhouse gas-saving, less harmful exhaust emissions).

    1999-04-27

    Waste handling and disposal from hydrocarbon exploration, drilling, and production are regulated by the US Environmental Protection Agency (EPA) through federal and state regulations and/or through implementation of federal regulations. Some wastes generated in these operations are exempt under the Resource Conservation and Recovery Act (RCRA) but are not exempt under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), Superfund Amendments and Reauthorization Act (SARA), and other federal environmental laws. Exempt wastes remain exempt only if they are not mixed with hazardous wastes or hazardous substances. Once mixture occurs, the waste must be disposed as a hazardous material in an approved hazardous waste disposal facility. Before the Clean Air Act as amended in 1990, air emissions from production, storage, steam generation, and compression facilities associated with hydrocarbon exploration, drilling, and production industry were not regulated. A critical proposed regulatory change which will significantly effect Class II injection wells for disposal of produced brine and injection for enhanced oil recovery is imminent. Federal regulations affecting hydrocarbon exploration, drilling and production, proposed EPA regulatory changes, and a recent significant US Court of Appeals decision are covered in this report. It appears that this industry will, in the future, fall under more stringent environmental regulations leading to increased costs for operators.

    The state enterprise 'Priargunsky Mining and Chemical Production Association' (PPGHO) is the only active uranium production centre in Russia in last decade. Mining has been operated since 1968 by two open pits and four underground mines. It is based on resources of 19 volcanic-type deposits of Streltsovsk U-ore region situated at the area of 150 km 2 . Milling and processing has been carried out since 1974 at the local hydrometallurgical plant. Since the mid 1980s, limited amount of uranium is produced by heap and block leaching methods. High level of total production marks PPGHO as one of the outstanding uranium production centers worldwide. Significant amount of solid, liquid and gas wastes have been generated for more than 30 years. The principal environmental contamination comes from waste rock piles, mine water and tailing ponds. Liquid waste seepage through tailing pond bed can essentially contaminate underground waters. The principal environmental remediation activities are: waste rock dumps and open pits rehabilitation; waste rock utilization for industrial needs; heap and block leaching mining development, strengthening dam bodies and construction intercepting wells below the tailing pond dam, hydrogeological monitoring, upgrade of mine water treatment unit. Waste is being managed by the environmental service team of PPGHO. Environmental restoration activities, including rehabilitation of the territories and waste utilization, are implemented gradually in line with decommissioning of enterprise's particular facilities.

    Natural resources are deteriorating very rapidly in the Gulf of Guayaquil and the area of influence in the Guayas Basin due to human activity. Specific problems are generated by the mismanagement of the aquaculture industry affecting the traditional agricultural sectors: rice, banana, sugarcane, cocoa, coffee, and soya also studied, and by human and industrial settlements. The development of industrial activities such as aquaculture (shrimp building for shrimp farming in ponds) and agriculture, have increasingly contributed to the generation of waste, degrading and potentially toxic elements in high concentrations, which can have adverse effects on organisms in the ecosystems, in the health of the population and damage the ecological and environmental balance. The productive Guayas ecosystem, consists of three interrelated ecosystems, the Gulf of Guayaquil, the Guayas River estuary and the Guayas Basin buffer. The objective of this study was to evaluate the environmental quality of the productive Guayas ecosystem (Ecuador), through operational and specific objectives: 1) Draw up the transition coastal zone in the Gulf of Guayaquil, 2) Set temporal spatial variability of soil salinity in wetlands rice, Lower Guayas Basin, 3) evaluate the heavy metals in wetland rice in the Lower Basin of Guayas. The physical and chemical parameters of the soils have been studied. These are indicators of environmental quality. The multivariate statistical method showed the relations of similarities and dissimilarities between variables and parameter studies as stable. Moreover, the boundaries of coastal transition areas, temporal spatial variability of soil salinity and heavy metals in rice cultivation in the Lower Basin of Guayas were researched. The sequential studies included and discussed represent a broad framework of fundamental issues that has been valued as a basic component of the productive Guayas ecosystem. They are determinants of the environmental quality of the Guayas

    2012-01-01

    A renewable biofuel economy is projected as a pathway to decrease dependence on fossil fuels as well as to reduce greenhouse gases (GHG) emissions. Ethanol produced on large-scale from lignocellulosic materials is considered the automotive fuel with the highest potential. In this paper, a life cycle assessment (LCA) study was developed to evaluate the environmental implications of the production of ethanol from a fast-growing short rotation crop (SRC): eucalyptus as well as its use in a flexi-fuel vehicle (FFV). The aim of the analysis was to assess the environmental performance of three ethanol based formulations: E10, E85 and E100, in comparison with conventional gasoline. The standard framework of LCA from International Standards Organization was followed and the system boundaries included the cultivation of the eucalyptus biomass, the processing to ethanol conversion, the blending with gasoline (when required) and the final use of fuels. The environmental results show reductions in all impact categories under assessment when shifting to ethanol based fuels, excluding photochemical oxidant formation, eutrophication as well as terrestrial and marine ecotoxicity which were considerably influenced by upstream activities related to ethanol manufacture. The LCA study remarked those stages where the researchers and technicians need to work to improve the environmental performance. Special attention must be paid on ethanol production related activities, such as on-site energy generation and distillation, as well as forest activities oriented to the biomass production. The use of forest machinery with higher efficiency levels, reduction of fertilizers dose and the control of diffuse emissions from the conversion plant would improve the environmental profile. -- Highlights: ► The identification of the environmental implications of the production and use of eucalyptus based ethanol was carried out. ► Eucalyptus is a Spanish common and abundant fast-growing short

    Ceramics, with regard to their status as largely everlasting everyday object as well as on the basis of their chronological sensitivity, reflect despite their simplicity the technological level of a culture and therefore also, directly or indirectly, the adaptability of a culture with respect to environmental and/or climatic changes. For that reason the question arises, if it is possible to identify changes in production techniques and raw material sources for ceramic production, as a response to environmental change, e.g. climate change. This paper will present results of a research about Paracas Culture (800 - 200 BC), southern Peru. Through several investigations (e.g. Schittek et al., 2014; Eitel and Mächtle, 2009) it is well known that during Paracas period changes in climate and environmental conditions take place. As a consequence, settlement patterns shifted several times through the various stages of Paracas time. Ceramics from three different sites (Jauranga, Cutamalla, Collanco) and temporal phases of the Paracas period are detailed archaeometric, geochemical and mineralogical characterized, e.g. Raman spectroscopy, XRD, and ICP-MS analyses. The aim of this research is to resolve potential differences in the chemical composition of the Paracas ceramics in space and time and to compare the data with the data sets of pre-Columbian environmental conditions. Thus influences of changing environmental conditions on human societies and their cultural conditions will be discussed. References Eitel, B. and Mächtle, B. 2009.

    Environmental tax reform (ETR), a shift in taxation towards environmental taxes, has been implemented on a small scale in a number of European countries. This paper first gives a short review of the literature about ETR. An Appendix briefly describes the model used for a modelling exercise to explore, through scenarios with low and high international energy prices, the implications of a large-scale ETR in the European Union, sufficient to reach the EU's emission reduction targets for 2020. The paper then reports the results of the exercise. The ETR results in increased carbon and materials, but reduced labour, productivity, with the emission reductions distributed across all sectors as a reduction in the demand for all fossil fuels. There are also small GDP increases for most, but not all, EU countries for all the scenarios, and for the EU as a whole. Both the environmental and macroeconomic outcomes are better with low than with high energy prices, because the former both increases the scale of the ETR required to reach the targets, and reduces the outflow of foreign exchange to pay for energy imports. ETR emerges from the exercise as an attractive and cost-effective policy for environmental improvement. - Highlights: ► European experience with environmental tax reform (ETR) is reviewed. ► Scenarios which meet EU carbon emission targets are modelled. ► The ETR results in increased carbon and materials, but reduced labour, productivity. ► There are small GDP increases for most, but not all, EU countries. ► ETR emerges as an attractive and cost-effective environmental policy.

    Full Text Available Platinum group elements (PGEs, 6E PGE = Pt + Pd + Rh + Ru + Ir + Au are used in numerous applications that seek to reduce environmental impacts of mobility and energy generation. Consequently, the future demand for PGEs is predicted to increase. Previous studies indicate that environmental impacts of PGE production change over time emphasizing the need of up-to-date data and assessments. In this context, an analysis of environmental aspects of PGE production is needed to support the environmental assessment of technologies using PGEs, to reveal environmental hotspots within the production chain and to identify optimization potential. Therefore, this paper assesses greenhouse gas (GHG emissions, cumulative fossil energy demand (CEDfossil, sulfur dioxide (SO2 emissions and water use of primary PGE production in Southern Africa, where most of today’s supply originates from. The analysis shows that in 2015, emissions amounted to 45 t CO2-eq. and 502 kg SO2 per kg 6E PGE in the case GHG and SO2 emissions, respectively. GHG emissions are dominated by emissions from electricity provision contributing more than 90% to the overall GHG emissions. The CEDfossil amounted to 0.60 TJ per kg 6E PGE. A detailed analysis of the CEDfossil reveals that electricity provision based on coal power consumes the most fossil energy carriers among all energy forms. Results show that the emissions are directly related to the electricity demand. Thus, the reduction in the electricity demand presents the major lever to reduce the consumption of fossil energy resources and the emission of GHGs and SO2. In 2015, the water withdrawal amounted to 0.272 million L per kg 6E PGE. Additionally, 0.402 million L of recycled water were used per kg 6E PGE. All assessed indicators except ore grades and production volumes reveal increasing trends in the period from 2010 to 2015. It can be concluded that difficult market conditions (see part I of this paper series and increasing

Conference participants defined their right to communicate as including freedom of expression, the free circulation of ideas, the right to information, the right to access communication channels, the right to women's channels and the production of communication messages, the right to have appropriate legal frameworks and economic/technological conditions for development, and the right to participate at decision-making levels in public and private communication organizations. The participants called for development of appropriate legislation, governmental policies, and codes of medical ethics; acknowledgement of the right of citizens to participate in the creation of regulations; and observation of relevant UN treaties and conventions. The women also condemned the increasing amount of violence suffered by journalists and asked governments not to place a statute of limitations on such crimes.

    The leaders of the European Union (EU) and the United States of America (USA) met June 2006 in Vienna to respond to the concerns of their citizens for peace, security, stability and prosperity in an increasingly globalised world. They welcome that over the past year the Transatlantic Partnership has delivered real results as shown by the political and economic Progress Reports issued during the summit (http://www.eu2006.at/en/The_Council_Presidency/EU-USSummit/index.html). They remain committed to finding common or complementary lines of action in many areas. Over the last year there have been many examples of how productive the relationship is, in the Middle East, Iran, the Western Balkans, Belarus, on the frozen conflicts, and Sudan, as well as in the efforts to promote transatlantic trade and investment under last Summit's Economic Initiative. They have decided to further strengthen the strategic Partnership by adopting a number of priority actions to support cooperation in the following four areas: Promoting peace, human rights and democracy worldwide; Confronting global challenges, including security; Fostering prosperity and opportunity; and Promoting strategic cooperation on energy and energy security, climate change and sustainable development

    This article reviews the different sources of energy used for electricity production in the view of the impact on environment. Coal, gas, wind energy, nuclear energy and hydro-energy are considered. The comparison of environmental performances requires common methodologies, 2 methodologies have been used ACV (analysis of a complete life cycle) and IPM (impact pathway methodology), both study all the exchanges of a system with the outside. The environmental performance is quantified by a series of parameters which represent the degradation of ecosystems. These parameters are divided into 4 groups: i) impact on public health, ii) impact on staff health, iii) impact on regional environment (agriculture, landscape alteration...) and iv) global impact on environment (greenhouse effect, acid rain, waste production, reduction of resources...).

    The paper evaluates the role of the bio-fuels production in the transportation sector in the world, for programs of greenhouse gases emissions reductions and sustainable environmental performance. Depending on the methodology used to account for the local pollutant emissions and the global greenhouse gases emissions during the production and consumption of both the fossil and bio-fuels, the results can show huge differences. If it is taken into account a life cycle inventory approach to compare the different fuel sources, these results can present controversies. A comparison study involving the American oil diesel and soybean diesel developed by the National Renewable Energy Laboratory presents CO{sub 2} emissions for the bio-diesel which are almost 20% of the emissions for the oil diesel: 136 g CO{sub 2}/bhp-h for the bio-diesel from soybean and 633 g CO{sub 2}/bhp-h for the oil diesel [National Renewable Energy Laboratory - NREL/SR-580-24089]. Besides that, important local environmental impacts can also make a big difference. The water consumption in the soybean production is much larger in comparison with the water consumption for the diesel production [National Renewable Energy Laboratory - NREL/SR-580-24089]. Brazil has an important role to play in this scenario because of its large experience in bio-fuels production since the seventies, and the country has conditions to produce bio-fuels for attending great part of the world demand in a sustainable pathway.

    Ghose, Mrinal K

    2009-07-01

    The global energy requirement has grown at a phenomenon rate and the consumption of primary energy sources has been a very high positive growth. This paper focuses on the consumption of different primary energy sources and it identifies that coal will continue to remain as the prime energy source in foreseeable future. It examines the energy requirement perspective for India and demand of coal as the prime energy source. Economic development and poverty alleviation depend on securing affordable energy sources and Indian coal mining industry offers a bright future for the country's energy security, provided the industry is allowed to develop by supportive government policies and adopts latest technologies for mining. It is an irony that in-spite of having a plentiful reserves, India is not able to jack up coal production to meet its current and future demand. It discusses the strategies to be adopted for growth and meeting the coal demand. But such energy are very much concerned with environmental degradation and must be driven by contemporary managerial acumen addressing environmental and social challenges effectively The paper highlights the emissions of greenhouse gases due to burning of fossil fuels and environmental consequences of global warming and sea-level rise. Technological solutions for environment friendly coal mining and environmental laws for the abatement of environmental degradation are discussed in this paper.

    The mission of the Department of Energy's (DOE) Feed Materials Production Center (FMPC) has been to process uranium for United States' defense programs. On July 10, 1989, the FMPC suspended production operations, but remains on standby for certain segments of production. The FMPC also manages the storage of some radioactive and hazardous materials. As part of its operations, the FMPC continuously monitors the environment to determine that it is operating within federal and state standards and guidelines regarding emission of radioactive and nonradioactive materials. Data collected from the FMPC monitoring program are used to calculate estimates of radiation dose for residents due to FMPC operations. For 1989, the estimate of dose through the air pathway, excluding radon, indicated that people in the area were exposed to less than 6% of the DOE guideline established to protect the public from radiation exposure. When radon emissions are included, the dose from FMPC operations during 1989 was less than 22% of the annual background radiation dose in the Greater Cincinnati area. This report is a summary of FMPC's environmental activities and monitoring program for 1989. An Environmental Compliance Self-Assessment presents the FMPC's efforts to comply with environmental regulations through June 1990. 44 refs., 48 figs.

  1. Floating on the margins [Environmental issues for floating production platforms

    Grimshaw, R.

    1997-01-01

    The main environmental issues challenging oilfield development using floating production platforms in harsh environments such as the Atlantic frontier are discussed. These fall into two broad categories -operating conditions and biological disturbance. Particular combinations of wind and currents can lead to extremely difficult operating conditions through which floating units are expected to maintain production for economic reasons. This imposes stringent conditions on the design and construction of tanker hulls and of risers to enable them to remain connected at all times. Prediction of wind and wave forces is a crucial element of operational and safety planning. Fauna in seabed sediments disturbed by pipeline laying often relocate but some seeding back of colonies may be required in hard rock areas. Migration routes for cetaceans and the feeding grounds of marine birds must be considered and the potential long and short term damage to commercial fisheries through discharges need to be assessed. A significant risk is the interaction of sub-sea facilities and fishing gear and oil spills. Operational and accidental discharges of production chemicals, produced water containing oil, deck drainage and treated sewage, and discharges to air from flaring and utility exhausts are of major environmental concern calling for mitigation and protection measures and contingency plans. Some of the environmental issues associated with decommissioning are reduced by the use of floating platforms but there are global and national regulations governing the process. (UK)

    Full Text Available Considering the present scenario of globalization of the economy, the dynamics of the market determines the speed of change in business models, environmental aspects can contribute to the design of technological innovations. Given this perception, the general objective of this research was to investigate how industrial organizations in the metal-mechanic sector, located in the Vale do Rio dos Sinos region, reconcile the product innovation activities and processes, with the structuring principles of environmental management. This economic segment is characterized as one that has the highest rates of innovation and greater investment in research and development. Data were collected through a survey research with managers of 159 companies of the analysis unit. Evidence collected provided the realization that innovations tend to be adjustments made to the legal provisions that require the mitigation of environmental impacts in the production process, especially in reducing pollution and using less toxic assets, which does not generate sufficient stimulus to the development of new products.

    Full Text Available In the paper there are presented system approaches, applied in Slovak transformed production enterprises, which solve questions of closing the so called industrial cycle from the side of the wastes' producers. The production quality is connected not only with the technological chain itself and with outputs from it - the utility product, but also with the load of the life environment.The presented possibilities of the liquidation of solid energetic waste – fly ashes – represent a an overview of forms and methods of its utilization. By combusting one kind of coal in various boilers, fly ashes with different physical, chemical, and mineralogical properties originate, with the combustion temperature as a dominant factor. The fly ashes are directly (without influencing its composition applied in civil engineering, mining, metallurgy, waste water cleaning, etc. Their utilization after a separation removal of unwanted components is an economically difficult process. Such a unvaluable component is coal combustion residue, evaluated by the annealing loss (carbon-in-ash loss in fly ashes used for special procedures in civil enginering, e.g. in mortars (maximally 4% of c.a.s. loss or in the porous concrete (4-7% of c.a.s. loss. The building industry processes about 20% of solid energetic waste.

    Highlights: ► Integrated bioenergy systems can favor the sustainability of biofuels. ► We analyzed the integrated production of ethanol and biodiesel in Brazil. ► GHG emissions and fossil energy use in the ethanol life cycle would be reduced. ► Socio-economic and other environmental aspects must be analyzed in future works. -- Abstract: The biorefinery of the future will be an integrated complex that makes a variety of products (e.g., biofuels, chemicals, power and protein) from a variety of feedstocks. The objective of this work was to evaluate the environmental benefits, compared to the traditional sugarcane ethanol system, of the integrated production of ethanol and biodiesel through a sugarcane–soybean biorefinery concept in Brazil. The environmental aspects considered here were the fossil energy use and the greenhouse gases (GHGs) emissions associated with ethanol production. In the Integrated System, soybean would be cultivated in part of the sugarcane reforming areas, which represents ∼17% of the total sugarcane area. Sugarcane and soybean oil would be processed in a combined ethanol–biodiesel plant, which would use only bagasse as fuel. All the demand for utilities of the biodiesel plant would be provided by the distillery. The output products of the combined plant would comprise sugarcane ethanol, soybean biodiesel (which would be used as diesel (B5) substitute in the sugarcane cultivation), bioelectricity and glycerin. The results indicate that the Integrated System can reduce the fossil energy consumption from 75 to 37 kJ/MJ of ethanol, when compared to the traditional system. For GHG emissions, the value would drop from 22.5 to 19.7 g CO 2 eq/MJ of ethanol. This analysis shows that the Integrated System is an important option to contribute to ethanol’s life cycle independence from fossil resources. This is an attractive environmental aspect, but socio-economic (as well as other environmental) aspects should also be analyzed in order to

    There is general consensus that the global demand for oil will increase in the medium-to-long term. It is predicted that much of this additional demand will be for OPEC oil. Therefore, it will become necessary to expand OPEC production capacity to meet this perceived increase. In recent years, many OPEC countries have launched far-reaching and, in some cases, radical plans to expand their production capacity. However, given the various investment and political constraints faced by the 13 OPEC Members, each country differs markedly in its ability to boost production capacity sufficiently to meet self-imposed targets. In this paper, we examine the importance to the oil market of recent oil supply trends and possible future attempts to build OPEC production capacity, focussing in particular on the legal and environmental issues involved. A review is provided of the legal mechanisms currently evolving in OPEC Countries to encourage investment in their oil industries. In addition, we outline the impact of the environmental movement of OPEC's expansion programmes. (author)

    Easterly, J.L.; Dunn, S.M.

    1995-01-01

    The purpose of this paper is to provide a broad overview of the environmental impacts associated with the production, conversion and utilization of biomass energy resources and compare them with the impacts of conventional fuels. The use of sustainable biomass resources can play an important role in helping developing nations meet their rapidly growing energy needs, while providing significant environmental advantages over the use of fossil fuels. Two of the most important environmental benefits biomass energy offers are reduced net emissions of greenhouse gases, particularly CO 2 , and reduced emissions of SO 2 , the primary contributor to acid rain. The paper also addresses the environmental impacts of supplying a range of specific biomass resources, including forest-based resources, numerous types of biomass residues and energy crops. Some of the benefits offered by the various biomass supplies include support for improved forest management, improved waste management, reduced air emissions (by eliminating the need for open-field burning of residues) and reduced soil erosion (for example, where perennial energy crops are planted on degraded or deforested land). The environmental impacts of a range of biomass conversion technologies are also addressed, including those from the thermochemical processing of biomass (including direct combustion in residential wood stoves and industrial-scale boilers, gasification and pyrolysis); biochemical processing (anaerobic digestion and fermentation); and chemical processing (extraction of organic oils). In addition to reducing CO 2 and SO 2 , other environmental benefits of biomass conversion technologies include the distinctly lower toxicity of the ash compared to coal ash, reduced odours and pathogens from manure, reduced vehicle emissions of CO 2 , with the use of ethanol fuel blends, and reduced particulate and hydrocarbon emissions where biodiesel is used as a substitute for diesel fuel. In general, the key elements for

    Full text: Bio fuel production and use have been discussed this time in EC and in Latvia as alternative energy sources. The national resources allow producing liquid fuels - bio diesel and bi oethanol from rape seeds and grain correspondingly. Liquid bio fuels can be recommended especially for auto transport in big towns to reduce the pollution of air. A system for environmentally friendly production of bio fuel from agricultural raw materials has been developed, which permit a complex utilization of byproducts an wastes for obtaining of valuable food-stuffs and industrial products, providing the agricultural production requirements and supporting with local mineral fertilizers. Such a bio fuel production includes the agricultural and industrial productions in a united biotechnological system. Production objects of system interact: the products, by-products and wastes from one object are used as raw materials, auxiliary materials or heat carriers in other system's objects. This integrated agro-industrial production system would allow the production of feeds and chemical products, along with bio fuels. In this work, a model of a system for a conventional administrative rural region is presented, exemplified with the case of Latvia. The model is developed for three forms of bio fuel production, i.e. ethanol, bio diesel and biogas as local energy source. Bio diesel is produced using ethanol as transesterifying agent of rape-seed oil fatty acids. This bio diesel is a blend of rape-seed oil fatty acid ethyl esters (REE) and consists solely from renewable raw materials. The capacity of distillery of system is 40 million litters per year and bio diesel 35000 ton. Important for agriculture is protein reach press cakes the byproduct from bio diesel production (66000 t/y). This byproduct can be exported as well. Biogas reactors of system can be used for utilization of wastes from town if necessary. Recommended bio system occupates up to 150.000 ha of agriculture lands

    Cigarette butts and other tobacco product wastes (TPW) are the most common items picked up in urban and beach cleanups worldwide. TPW contains all the toxins, nicotine, and carcinogens found in tobacco products, along with the plastic nonbiodegradable filter attached to almost all cigarettes sold in the United States and in most countries worldwide. Toxicity studies suggest that compounds leached from cigarette butts in salt and fresh water are toxic to aquatic micro-organisms and test fish. Toxic chemicals have also been identified in roadside TPW. With as much as two-thirds of all smoked cigarettes (numbering in the trillions globally) being discarded into the environment each year, it is critical to consider the potential toxicity and remediation of these waste products. This article reviews reports on the toxicity of TPW and recommends several policy approaches to mitigation of this ubiquitous environmental blight.

    Primary copper production is a major activity in the mining sector of several countries. However, it is highly energy-intensive and poses important environmental hazards. In the case of Chile, the world's largest copper producer (40% of world total), we examine its energy consumption and energy-related environmental implications over a time horizon of 25 years. Concerning the latter, we focus on greenhouse-gas (GHG) emissions, one of the most debated environmental issues. This paper follows up our previous report in which the current situation was analyzed and a particular technical option for improving the energy efficiency and concurrently reducing GHG emissions was discussed. Estimated reference or base (BS) and mitigation (MS) scenarios are developed for the period ending in 2020. The former assesses the energy demand projected in accordance with production forecasts and specific energy consumption patterns (assuming that energy efficiency measures are adopted 'spontaneously') with their resultant GHG emissions, while the latter assumes induced actions intended to reduce emissions by adopting an aggressive policy of efficient energy use. For the year 2020, the main results are: (i) BS, 1214 t of CO{sub 2}/ton of refined copper content (49% lower than in 1994); (ii) MS, 1037 t of CO{sub 2}/t of refined copper content (56% lower than in 1994). CO{sub 2} emissions have been estimated considering both fuel and electricity process requirements. (author)

    Superhydrophobic materials hold an enormous potential in sectors as important as aerospace, food industries, or biomedicine. Despite this great promise, the lack of environmentally friendly production methods and limited robustness remain the two most pertinent barriers to the scalability, large-area production, and widespread use of superhydrophobic materials. In this work, highly robust superhydrophobic silicone monoliths are produced through a scalable and environmentally friendly emulsion technique. It is first found that stable and surfactantless water-in-polydimethylsiloxane (PDMS) emulsions can be formed through mechanical mixing. Increasing the internal phase fraction of the precursor emulsion is found to increase porosity and microtexture of the final monoliths, rendering them superhydrophobic. Silica nanoparticles can also be dispersed in the aqueous internal phase to create micro/nanotextured monoliths, giving further improvements in superhydrophobicity. Due to the elastomeric nature of PDMS, superhydrophobicity can be maintained even while the material is mechanically strained or compressed. In addition, because of their self-similarity, the monoliths show outstanding robustness to knife-scratch, tape-peel, and finger-wipe tests, as well as rigorous sandpaper abrasion. Superhydrophobicity was also unchanged when exposed to adverse environmental conditions including corrosive solutions, UV light, extreme temperatures, and high-energy droplet impact. Finally, important properties for eventual adoption in real-world applications including self-cleaning, stain-repellence, and blood-repellence are demonstrated.

    This paper provides a panorama of environmental protection activities being undertaken by AGIP (Italian General Petroleum Company). The Company has developed a wide-ranging program based on 20 years experience in world-wide on- and off-shore exploration and production. The research studies on technologically innovative on-site waste management, noise abatement and subsidence control and monitoring techniques are co-operative efforts involving the joint participation of national research institutions, universities and leading international petroleum companies. Given the intense oil carrier traffic along Italy's tourism dependent coastlines, one of the key projects is the creation of a national emergency plan to deal with oil spills. AGIP is also actively involved in the training of national and foreign site personnel in environmental protection techniques

    Clean and affordable power production is needed in order to achieve sustainable economic development. This paper focused on clean coal technologies in which coal-fired power plants are used in conjunction with large amounts of renewable energy sources to offer a high level of process safety and long term management of all residual operation streams. Thermal Desorption Recycle-Reduce-Reuse Technology (TDT-3R) was described as being a promising solid fuel pretreatment process for clean energy production up to 300 MWe capacities. TDT-3R is based on low temperature carbonisation fuel pre-treatment principles, which produce cleansed anthracite type fuels from coal and other carbonaceous material such as biomass and organic wastes. The combustion efficiency of such clean coals and the environmental performance of the TDT-3R process were investigated in this study via pilot scale tests of clean fuel production. Tests included flue gas emissions monitoring, raw fuel and product characterisation and thermogravimetric tests, polychlorinated dibenzo-p-dioxins and dibenzo-furans, and heavy metals analyses, and toxicity tests. Raw material included coal and biomass, such as willow, straw and demolition wood. The fuels were heated in a rotary kiln operating at 550 degrees C under slightly vacuum conditions. Clean coals were tested either alone or in conjunction with biomass fuels in a pilot scale combustion facility at Dresden, Germany. The clean coal samples were shown to have higher fixed carbon and ash content and lower volatiles compared to the respective raw coal samples. The major advantage of the TDT-3R process is the production of fuels with much lower pollutants content. Low nitrogen, sulphur, chlorine and heavy metal contents result in produced fuels that have excellent environmental performance, allow boiler operation in higher temperatures and overall better efficiency. Moreover, the use of clean fuels reduces deposition problems in the combustion chamber due to the

    Until recently, arms control agreements were limited by the fact that the only available verification capabilities were national technical means, which involved instruments in space or beyond national borders. As a result, the SALT II treaty constrained only the construction of large missile silos, ballistic-missile submarines and long-range bombers - and limited the flight testing of long-range ballistic missiles. Recently, however, on-site verification has been accepted, making it possible in the INF treaty to extend controls to small mobile missiles and their launchers. This paper therefore outlines a comprehensive system of verifiable limits on nuclear warheads. The authors discuss in some detail the verifiability of a halt in the production of fissile materials for nuclear warheads, the verifiability of declarations of the amounts of fissile material produced for warheads prior to the production cutoff, and the establishment of a verifiable accounting system for the numbers and types of nuclear warheads possessed by each side

    This study evaluates life cycle environmental impacts associated with chocolate products made and consumed in the UK. The paper focuses on three representative chocolate products occupying 90% of the market: 'moulded chocolate', 'chocolate countlines' and 'chocolates in bag'. The impacts were estimated using life cycle assessment (LCA) as a tool and following the ReCiPe impact assessment method. The water footprint was also considered. For example, the global warming potential ranges between 2.91 and 4.15 kg CO 2 eq., primary energy demand from 30 to 41 MJ and the water footprint, including water stress, from 31 to 63 l per kilogram of chocolate. The raw materials are the major hotspot across all impact categories for all three product types, followed by the chocolate production process and packaging. The raw material impacts are mainly due to milk powder, cocoa derivatives, sugar and palm oil. The sensitivity analysis shows that the results for global warming potential are sensitive to land-use change (LUC) associated with cocoa production, increasing the impact of the chocolate products by three to four times if LUC is involved. The improvement opportunities targeting the key contributing stages suggest that GWP of chocolates could be reduced by 14%-19%. Chocolate countlines have the highest contribution to the total impacts at the UK level (37%-43%), followed by chocolates in bag (28%-33%). Moulded chocolates and other chocolate confectionary make up the rest of the impacts, with a roughly equal share each. Chocolate consumption in the UK contributes 4.7% to the primary energy consumption and 2.4% to the GHG emissions from the whole food and drink sector. The results of this work will be of interest to policy makers, chocolate producers and consumers, helping them to make more informed decisions towards sustainable production and consumption of chocolate products.

    This paper addresses the development of an environmental program for a large proposed federal project currently in the preliminary design phase, namely, the accelerator production of tritium (APT) for the US Department of Energy (DOE). This project is complicated not only by its size ($3.5 to $4.5 billion) but also by its technical complexity and one-of-a-kind nature. This is further complicated by the fact that government projects are driven by budgets subject to public pressures and annual Congressional fiscal considerations, whereas private companies are driven by profits. The measure of success for a federal project such as the APT is based on level of public support, not profits. Finally, there are not too many equivalent environmental programs that could be used as models, and benchmarking is nearly impossible. Forming an environmental program during the conceptual design phase of this large federal project included the formation of a core environmental working group (EWG). The group has membership from all major project organizations with a charter formally recognized by the project director. The envelope for traditional environmental work for the APT project has been stretched to include teaming with management in the establishment of project goals and direction. The APT EWG was set up organizationally to include several subgroups or teams that do the real work of assessing, establishing the regulatory framework, and then developing a compliance program. Setting aside the organizational difficulties of selecting the right team leads and members, each team was tasked with developing a charter, plan, and schedule. Since then, each team has developed an appropriate level of supporting documentation to address its particular issues and requirements

    kept under lock and key, and keys should be accessible to authorized personnel only. Alarm and gardiennage are not mandatory, but in some special cases, an alarm system has been required by the authority. It should be noted that these requirements are very often the same than those set by national authorities dealing with sealed radioactive sources. In the case of operators using gamma radiography devices, several regulations regarding licensing of sealed radioactive sources users, radiation protection of public and workers, and environmental protection, require physical protection measures in order to prevent theft of radioactive sources and to ensure their protection against fire or other damages. Usually, the arrangements made by the operator for the protection of devices containing both a radioactive source and nuclear material comply with the requirements related to physical protection of depleted uranium. This is not the case for empty devices whose radioactive source has been removed and for the accessories such as directional and panoramic collimators, transfer casks, trimmers, which contain DU and are not submitted to other regulations. Declarants are rended sensitive to that point in order they ensure the same level of physical protection to all devices containing DU, both used, useless or damaged. As an example, gammagraphy operators should not store and leave without surveillance these type of accessories inside vehicles, as the risk of theft is significant. In the medical field, trimmers may have been removed from the radiotherapy unit, and very often, shaping block made of DU, delivered with the unit, are not used by the medical personnel, because of their radioactivity. These items, containing a few kilograms of DU, have to be inventoried by the operators, labelled and kept under lock and key. When possible, operators are invited to return unused and damaged equipment to the manufacturer. In order to implement the declaration regime requirements, IPSN

    The energy requirements of many novel protein production systems are compared with an examination of the relevant environmental implications of these systems. The prospects for single cell protein, leaf protein, fish farming, fish protein concentrate, algal cultivation, and hydroponic plant growth systems are investigated. Single cell protein from carbohydrate substrates, algal protein, and fish protein seem to hold much promise, as they are technologically feasible for near-term implementation and do not require major energy inputs.

    This study was undertaken to evaluate the effect that switching from conventional to precision feeding systems during the growing-finishing phase would have on the potential environmental impact of Brazilian pig production. Standard life-cycle assessment procedures were used, with a cradle-to-farm gate boundary. The inputs and outputs of each interface of the life cycle (production of feed ingredients, processing in the feed industry, transportation and animal rearing) were organized in a model. Grain production was independently characterized in the Central-West and South regions of Brazil, whereas the pigs were raised in the South region. Three feeding programs were applied for growing-finishing pigs: conventional phase feeding by group (CON); precision daily feeding by group (PFG) (whole herd fed the same daily adjusted diet); and precision daily feeding by individual (PFI) (diets adjusted daily to match individual nutrient requirements). Raising pigs (1 t pig BW at farm gate) in South Brazil under the CON feeding program using grain cultivated in the same region led to emissions of 1840 kg of CO2-eq, 13.1 kg of PO4-eq and 32.2 kg of SO2-eq. Simulations using grain from the Central-West region showed a greater climate change impact. Compared with the previous scenario, a 17% increase in climate change impact was found when simulating with soybeans produced in Central-West Brazil, whereas a 28% increase was observed when simulating with corn and soybeans from Central-West Brazil. Compared with the CON feeding program, the PFG and PFI programs reduced the potential environmental impact. Applying the PFG program mitigated the potential climate change impact and eutrophication by up to 4%, and acidification impact by up to 3% compared with the CON program. Making a further adjustment by feeding pigs according to their individual nutrient requirements mitigated the potential climate change impact by up to 6% and the potential eutrophication and acidification impact

  8. Microalgal biomass production pathways: evaluation of life cycle environmental impacts.

    Microalgae are touted as an attractive alternative to traditional forms of biomass for biofuel production, due to high productivity, ability to be cultivated on marginal lands, and potential to utilize carbon dioxide (CO2) from industrial flue gas. This work examines the fossil energy return on investment (EROIfossil), greenhouse gas (GHG) emissions, and direct Water Demands (WD) of producing dried algal biomass through the cultivation of microalgae in Open Raceway Ponds (ORP) for 21 geographic locations in the contiguous United States (U.S.). For each location, comprehensive life cycle assessment (LCA) is performed for multiple microalgal biomass production pathways, consisting of a combination of cultivation and harvesting options. Results indicate that the EROIfossil for microalgae biomass vary from 0.38 to 1.08 with life cycle GHG emissions of -46.2 to 48.9 (g CO2 eq/MJ-biomass) and direct WDs of 20.8 to 38.8 (Liters/MJ-biomass) over the range of scenarios analyzed. Further anaylsis reveals that the EROIfossil for production pathways is relatively location invariant, and that algae's life cycle energy balance and GHG impacts are highly dependent on cultivation and harvesting parameters. Contrarily, algae's direct water demands were found to be highly sensitive to geographic location, and thus may be a constraining factor in sustainable algal-derived biofuel production. Additionally, scenarios with promising EROIfossil and GHG emissions profiles are plagued with high technological uncertainty. Given the high variability in microalgae's energy and environmental performance, careful evaluation of the algae-to-fuel supply chain is necessary to ensure the long-term sustainability of emerging algal biofuel systems. Alternative production scenarios and technologies may have the potential to reduce the critical demands of biomass production, and should be considered to make algae a viable and more efficient biofuel alternative.

  13. Environmental issues of petroleum exploration and production: Introduction

    Kharaka, Yousif K.; Dorsey, Nancy S.

    2005-01-01

    Energy is the lifeblood of our planet Earth, an essential commod- ity that powers the expanding global economy. Starting in the 1950s, oil and natural gas became the main sources of primary energy for the increasing world population, and this dominance is expected to continue for several more decades (Edwards, 1997; Energy Information Administration (EIA), 2004). In the United States, petroleum production started in 1859 when Drake's well was drilled near Titusville, Pennsylvania, and oil and natural gas currently supply approximately 63% of the energy consumption; forecasts indicate that by 2025, their use will increase by about 40% to 28.3 million bbl/day and to 31.4 tcf/yr (EIA, 2004). The clear benefits of petroleum consumption, however, can carry major environmental impacts that may be regional or global in scale, in- cluding air pollution, global climate change, and oil spills. This vol- ume of Environmental Geosciences, covering environmental impacts of petroleum exploration and production, does not address these major impacts directly because air pollution and global warming are issues related primarily to petroleum and coal uses, and major oil spills are generally attributed to marine petroleum transportation, such as the Exxon Valdez's 1989 spill of 260,000 bbl of oil into Prince William Sound, Alaska. Exploration for and production of petroleum, however, have caused local detrimental impacts to soils, surface and groundwa- ters, and ecosystems in the 36 producing states in the United States (Richter and Kreitler, 1993; Kharaka and Hanor, 2003). These im- pacts arose primarily from the improper disposal of some of the large volumes (presently estimated at 20 billion bbl/yr total pro- duced) of saline water produced with oil and gas, from accidental hydrocarbon and produced-water releases, and from abandoned oil wells that were orphaned or not correctly plugged (Kharaka et al., 1995; Veil et al., 2004).

    Declarative memory recall is thought to involve the reinstatement of neural activity patterns that occurred previously during encoding. Consistent with this view, greater similarity between patterns of activity recorded during encoding and retrieval has been found to predict better memory performance in a number of studies. Recent models have argued that neural oscillations may be crucial to reinstatement for successful memory retrieval. However, to date, no causal evidence has been provided to support this theory, nor has the impact of oscillatory electrical brain stimulation during encoding and retrieval been assessed. To explore this we used transcranial alternating current stimulation over the left dorsolateral prefrontal cortex of human participants [ n = 70, 45 females; age mean (SD) = 22.12 (2.16)] during a declarative memory task. Participants received either the same frequency during encoding and retrieval (60-60 or 90-90 Hz) or different frequencies (60-90 or 90-60 Hz). When frequencies matched there was a significant memory improvement (at both 60 and 90 Hz) relative to sham stimulation. No improvement occurred when frequencies mismatched. Our results provide support for the role of oscillatory reinstatement in memory retrieval. SIGNIFICANCE STATEMENT Recent neurobiological models of memory have argued that large-scale neural oscillations are reinstated to support successful memory retrieval. Here we used transcranial alternating current stimulation (tACS) to test these models. tACS has recently been shown to induce neural oscillations at the frequency stimulated. We stimulated over the left dorsolateral prefrontal cortex during a declarative memory task involving learning a set of words. We found that tACS applied at the same frequency during encoding and retrieval enhances memory. We also find no difference between the two applied frequencies. Thus our results are consistent with the proposal that reinstatement of neural oscillations during retrieval

    The International Lunar Decade Declaration was discussed at the conference held November 9-13, 2014 in Hawaii "The Next Giant Leap: Leveraging Lunar Assets for Sustainable Pathways to Space" - http://2014giantleap.aerospacehawaii.info/ and accepted by a core group that forms the International Lunar Decade Working Group (ILDWG) that is seeking to make the proposed global event and decade long process a reality. The Declaration will be updated from time to time by members of the ILDWreflecting new knowledge and fresh perspectives that bear on building a global consortium with a mission to progress from lunar exploration to the transformation of the Moon into a wealth gene rating platform for the expansion of humankind into the solar system. When key organizations have endorsed the idea and joined the effort the text of the Declaration will be considered final. An earlier International Lunar Decade proposal was issued at the 8th ICEUM Conference in 2006 in Beijing together with 13 specific initiatives for lunar exploration[1,2,3]. These initiatives have been largely implemented with coordination among the different space agencies involved provided by the International Lunar Exploration Working Group[2,3]. The Second International Lunar Decade from 2015 reflects current trends towards increasing involvement of commercial firms in space, particularly seeking opportunities beyond low Earth orbit. The central vision of the International Lunar Decade is to build the foundations for a sustainable space economy through international collaboration concurrently addressing Lunar exploration and building a shared knowledge base;Policy development that enables collabo rative research and development leading to lunar mining and industrial and commercial development;Infrastructure on the Moon and in cislunar space (communications, transport, energy systems, way-stations, other) that reduces costs, lowers risks and speeds up the time to profitable operations;Enabling technologies

    2006-01-01

    During the last 3 years, there has been a dramatic revival and comeback of the uranium industry in the light of the expanding nuclear power programme all over the world. As a result, there has been a boom in uranium exploration, mining and production activities to meet the higher demand of uranium and reduce the gap between uranium demand and uranium supply from mines. In coming years, additional requests for TC, training/workshop and CRPs are expected in the areas of: 1) advanced aerial and ground geophysical techniques for discovery of new deposits which could be deeply buried; 2) investigations of uranium sources in sedimentary, igneous and metamorphic environments; 3) In-Situ leaching (ISL) of uranium deposits; 4) advanced acid/alkali leaching of low, medium and high grade uranium ores and purification of uranium; 5) reclamation of used uranium mines and related environmental protection issues; and 6) uranium supply, demand and market issues. Services provided by the Nuclear Fuel Cycle and Materials Section could be workshops and hands-on field trainings at National and/or Regional levels in mines, mills and sites covering the following activities: uranium exploration involving conventional and advanced geophysical techniques and instruments, advanced drilling equipment and tools, etc.; uranium mining (open-cast and underground), recovery and purification by acid/alkali leaching, In-Situ leaching (ISL), purification by conventional and advanced solvent extraction and ion exchange techniques and concentration of uranium in the form of yellowcake (ammonium diuranate, magnesium diuranate and uranium peroxide); promoting best practices in uranium mining and milling (including tailing pond), covering environmental issues, reclamation of used uranium mines and chemistry of uranium production cycle and ground water and sustainability of uranium production.

    2017-01-01

    Full Text Available Recycled concrete aggregate is considered as the most abundant and used secondary aggregate in concrete production, other types of solid waste are also being used in concrete for specific purposes and to achieve some desired properties. Recycled aggregates and particularly, recycled concrete aggregate substantially affect the properties and mix design of concrete both at fresh and hardened states since it is known by high porosity due to the adhered layer of old mortar on the aggregate which results in a high water absorption of the recycled secondary aggregate. This leads to lower density and strength, and other durability related properties. The use of most recycled aggregate in concrete structures is still limited to low strength and non-structural applications due to important drop in strength and durability performances generated. Embedding recycled aggregates in concrete is now a current practice in many countries to enhance sustainability of concrete industry and reduce its environmental impacts. The present paper discusses the various possible recycled aggregates used in concrete production, their effect on both fresh and hardened properties as well as durability performances. The economic and environmental impacts of partially or fully substituting natural aggregates by secondary recycled aggregates are also discussed.

  19. Environmental effect of constructed wetland as biofuel production system

    Science.gov (United States)

    Liu, Dong

    2017-04-01

    Being as a renewable energy, biofuel has attracted worldwide attention. Clean biofuel production is an effective way to mitigate global climate change and energy crisis. Biofuel may offer a promising alternative to fossil fuels, but serious concerns arise about the adverse greenhouse gas consequences from using nitrogen fertilizers. Waste-nitrogen recycling is an attractive idea. Here we advocate a win-win approach to biofuel production which takes advantage of excessive nitrogen in domestic wastewater treated via constructed wetland (CW) in China. This study will carry on environmental effect analysis of CW as a biomass generation system through field surveys and controllable simulated experiments. This study intends to evaluate net energy balance, net greenhouse effect potential and ecosystem service of CW as biomass generation system, and make comparation with traditional wastewater treatment plant and other biofuel production systems. This study can provide a innovation mode in order to solve the dilemma between energy crops competed crops on production land and excessive nitrogen fertilizer of our traditional energy plant production. Data both from our experimental CWs in China and other researches on comparable CWs worldwide showed that the biomass energy yield of CWs can reach 182.3 GJ ha-1 yr-1, which was two to eight times higher than current biofuel-production systems. Energy output from CW was ˜137% greater than energy input for biofuel production. If CWs are designed with specific goal of biofuel production, biofuel production can be greatly enhanced through the optimization of N supply, hydraulic structures, and species selection in CWs. Assuming that 2.0 Tg (1 Tg = 1012 g) waste nitrogen contained in domestic wastewater is treated by CWs, biofuel production can account for 1.2% of national gasoline consumption in China. The proportion would increase to 6.7% if extra nitrogen (9.5 Tg) from industrial wastewater and agricultural runoff was included

    2014-12-01

    Full Text Available Demand for nickel is constantly growing due to the versatility of its application, at the first place for stainless steel production. Ore reserves and possibility of nickel production of today’s Serbia and in neighboring countries were thoroughly investigated, and presented work is part of a wider project of sublimation of scientific and professional experience in the field of nickel extractive metallurgy on domestic raw materials. Presented research explores the possibility of high pressure sulfuric acid leaching of Serbian lateritic ores from localities Rudjinci, Ba and Lipovac. All three investigated ore deposits behaved differently both during preparation and during hydrometallurgical treatment. As optimal method for ore preparation proved to be crushing-milling-sieving route, but without possibility of concentrate production. Only for Rudjinci ore deposit achieved leaching efficiency reached satisfactory level of 95%. Within presented paper flow-sheet is proposed for processing high-magnesium laterite ores, with iron and magnesium oxide Both could be recirculated and used again in technological process; MgO for iron precipitation and SO2 for production of leaching agent, sulfuric acid. Final decision on the sustainability of the process will be made according to techno-economic and environmental evaluation. Estimated overall impact of the project implementation on the environment is negative.

  1. Environmental impacts of biomass energy resource production and utilization

    Energy Technology Data Exchange (ETDEWEB)

    Easterly, J L; Dunn, S M [DynCorp, Alexandria, VA (United States)

    1995-12-01

    The purpose of this paper is to provide a broad overview of the environmental impacts associated with the production, conversion and utilization of biomass energy resources and compare them with the impacts of conventional fuels. The use of sustainable biomass resources can play an important role in helping developing nations meet their rapidly growing energy needs, while providing significant environmental advantages over the use of fossil fuels. Two of the most important environmental benefits biomass energy offers are reduced net emissions of greenhouse gases, particularly CO{sub 2}, and reduced emissions of SO{sub 2}, the primary contributor to acid rain. The paper also addresses the environmental impacts of supplying a range of specific biomass resources, including forest-based resources, numerous types of biomass residues and energy crops. Some of the benefits offered by the various biomass supplies include support for improved forest management, improved waste management, reduced air emissions (by eliminating the need for open-field burning of residues) and reduced soil erosion (for example, where perennial energy crops are planted on degraded or deforested land). The environmental impacts of a range of biomass conversion technologies are also addressed, including those from the thermochemical processing of biomass (including direct combustion in residential wood stoves and industrial-scale boilers, gasification and pyrolysis); biochemical processing (anaerobic digestion and fermentation); and chemical processing (extraction of organic oils). In addition to reducing CO{sub 2} and SO{sub 2}, other environmental benefits of biomass conversion technologies include the distinctly lower toxicity of the ash compared to coal ash, reduced odours and pathogens from manure, reduced vehicle emissions of CO{sub 2}, with the use of ethanol fuel blends, and reduced particulate and hydrocarbon emissions where biodiesel is used as a substitute for diesel fuel.

    The water of Lake Erie is used as a source of drinking water for Ontario, New York, Pennsylvania, Ohio and Michigan. An environmental review has been conducted to determine the impact of drilling operations on the overall ecology of the lake. Since 1913, 2000 natural gas wells have been drilled in Lake Erie, of which 550 currently produce gas and account for 75 per cent of Ontario's total gas production. 180 wells are shut-in or suspended and the remaining wells have been abandoned. The gas wells are connected to onshore production facilities by approximately 1,600 km of small diameter pipelines that lie buried near shore or on top of the lake bed. Nearly 90 per cent of the in-lake infrastructure is in water depths of more than 20 metres. Talisman Energy is actively involved with the Canadian Coast Guard, the Department of Fisheries and Oceans, and the Ministry of Natural Resources to ensure cooperation between regulators and off-shore personnel. The environmental assessment of natural gas production in Lake Erie included a review of regulatory and best management practices, a biophysical overview of the lake, and a review of drilling practices, well completions, handling of waste streams, materials management, operations inspections, wastewater discharge, air emissions, and oil spills. It was revealed that for most drilling programs, cuttings are washed and discharged to the Lake. Ongoing testing will determine the impact that this practice has on benthic populations. The drill muds used for drilling operations are water based, environmentally friendly, and re-used between well locations. For completion programs, all well activities are closed circuit operations. Wells are abandoned through plugging with cement, removing wellheads and casing below the lake bottom. There has been a reported volume of about 23,000 litres of spilled product from 1990 to 2001, of which 68 per cent has come from 3 industrial companies that operate near Lake Erie. The offshore gas

    The purpose of this study is to examine why both parties (industry and consumer market) have mutual interests in protecting the environment but they still are hesitant to act green. The study used two-stage sampling from consumer market to depict ideal green product characteristics and reliable toy companies, and visit these companies for the second sample collection to examine whether the organizational eco-innovation strategy with customer value has a positive effect on green product development. In other words, the customer's benefit is an important factor for new product development strategy for green toys. This research shows that the willingness to buy green toys increases if most people in society buy green toys. This represents that customers are environmentally conscious and care about protecting the environment, or buying green toys is the result of a new economic trend and childhood education. The willingness to buy green toys increases if customers think that green products implies an enhancement on new product development to toy manufacturers. Further, if manufacturers are able to manage the difficulty of cooperation with all parties in the supply chain and difficulties related to production, they are willing to adopt customers' perceived value on green toys for their new product development strategy. It is rare to find academic research discussing the perspectives of both consumers and manufacturers in the same study because the research topic is very broad and many conditions must be considered. This research aims to find the effect of consumer-perceived value and company eco-innovation on green product development.

    As part of a systemic assessment toward social sustainability of egg production, we have reviewed current knowledge about the environmental impacts of egg production systems and identified topics requiring further research. Currently, we know that 1) high-rise cage houses generally have poorer air quality and emit more ammonia than manure belt (MB) cage houses; 2) manure removal frequency in MB houses greatly affects ammonia emissions; 3) emissions from manure storage are largely affected by storage conditions, including ventilation rate, manure moisture content, air temperature, and stacking profile; 4) more baseline data on air emissions from high-rise and MB houses are being collected in the United States to complement earlier measurements; 5) noncage houses generally have poorer air quality (ammonia and dust levels) than cage houses; 6) noncage houses tend to be colder during cold weather due to a lower stocking density than caged houses, leading to greater feed and fuel energy use; 7) hens in noncage houses are less efficient in resource (feed, energy, and land) utilization, leading to a greater carbon footprint; 8) excessive application of hen manure to cropland can lead to nutrient runoff to water bodies; 9) hen manure on open (free) range may be subject to runoff during rainfall, although quantitative data are lacking; 10) mitigation technologies exist to reduce generation and emission of noxious gases and dust; however, work is needed to evaluate their economic feasibility and optimize design; and 11) dietary modification shows promise for mitigating emissions. Further research is needed on 1) indoor air quality, barn emissions, thermal conditions, and energy use in alternative hen housing systems (1-story floor, aviary, and enriched cage systems), along with conventional housing systems under different production conditions; 2) environmental footprint for different US egg production systems through life cycle assessment; 3) practical means to mitigate air

  6. Potential Fusion Market for Hydrogen Production Under Environmental Constraints

    2005-01-01

    Potential future hydrogen market and possible applications of fusion were analyzed. Hydrogen is expected as a major energy and fuel mediun for the future, and various processes for hydrogen production can be considered as candidates for the use of fusion energy. In order to significantly contribute to reduction of CO 2 emission, fusion must be deployed in developing countries, and must substitute fossil based energy with synthetic fuel such as hydrogen. Hydrogen production processes will have to evaluated and compared from the aspects of energy efficiency and CO 2 emission. Fusion can provide high temperature heat that is suitable for vapor electrolysis, thermo-chemical water decomposition and steam reforming with biomass waste. That is a possible advantage of fusion over renewables and Light water power reactor. Despite of its technical difficulty, fusion is also expected to have less limitation for siting location in the developing countries. Under environmental constraints, fusion has a chance to be a major primary energy source, and production of hydrogen enhances its contribution, while in 'business as usual', fusion will not be selected in the market. Thus if fusion is to be largely used in the future, meeting socio-economic requirements would be important

    With the MEP subsidy regulation 'Environmental quality of electricity production' The Dutch minister of Economic Affairs focussed mainly on reaching the policy objective of the EU according to which 9% of all electricity used in the Netherlands should be generated with sustainable sources. According to the opinion of the Dutch Court of Audits not enough attention has been paid to the coherence of the MEP regulation with other policy objectives in the area of sustainability, such as air quality and CO2 reduction. The same goes for the effectiveness and the financial management of the MEP regulation. Moreover, the study, which was carried out by request of the Dutch Lower House, demonstrates that it is still uncertain if the policy objective for 2010 will be reached. The report consists of two parts: part 1: Conclusions, recommendations and administrative reactions, and Part 2: Answering Lower House questions.(mk) [nl

    The Alaska North Slope offers one of the best prospects for increasing U.S. domestic oil and gas production. However, this region faces some of the greatest environmental and logistical challenges to oil and gas production in the world. A number of studies have shown that weather patterns in this region are warming, and the number of days the tundra surface is adequately frozen for tundra travel each year has declined. Operators are not allowed to explore in undeveloped areas until the tundra is sufficiently frozen and adequate snow cover is present. Spring breakup then forces rapid evacuation of the area prior to snowmelt. Using the best available methods, exploration in remote arctic areas can take up to three years to identify a commercial discovery, and then years to build the infrastructure to develop and produce. This makes new exploration costly. It also increases the costs of maintaining field infrastructure, pipeline inspections, and environmental restoration efforts. New technologies are needed, or oil and gas resources may never be developed outside limited exploration stepouts from existing infrastructure. Industry has identified certain low-impact technologies suitable for operations, and has made improvements to reduce the footprint and impact on the environment. Additional improvements are needed for exploration and economic field development and end-of-field restoration. One operator-Anadarko Petroleum Corporation-built a prototype platform for drilling wells in the Arctic that is elevated, modular, and mobile. The system was tested while drilling one of the first hydrate exploration wells in Alaska during 2003-2004. This technology was identified as a potentially enabling technology by the ongoing Joint Industry Program (JIP) Environmentally Friendly Drilling (EFD) program. The EFD is headed by Texas A&M University and the Houston Advanced Research Center (HARC), and is co-funded by the National Energy Technology Laboratory (NETL). The EFD

    In the current study, conventional resources-based ammonia generation routes are comparatively studied through a comprehensive life cycle assessment. The selected ammonia generation options range from mostly used steam methane reforming to partial oxidation of heavy oil. The chosen ammonia synthesis process is the most common commercially available Haber-Bosch process. The essential energy input for the methods are used from various conventional resources such as coal, nuclear, natural gas and heavy oil. Using the life cycle assessment methodology, the environmental impacts of selected methods are identified and quantified from cradle to gate. The life cycle assessment outcomes of the conventional resources based ammonia production routes show that nuclear electrolysis-based ammonia generation method yields the lowest global warming and climate change impacts while the coal-based electrolysis options bring higher environmental problems. The calculated greenhouse gas emission from nuclear-based electrolysis is 0.48 kg CO2 equivalent while it is 13.6 kg CO2 per kg of ammonia for coal-based electrolysis method.

    1999-07-01

    Commercialization of fluidized bed combustion (FBC) technology could be enhanced by increased utilization of FBC products (ash). In the US, coal combustion products (CCP) are not hazardous under RCRA and are regulated as residual waste by the states. The composition of CCP from fluidized beds is primarily determined by the inorganic constituents in coal, the sorbent reaction products and the unreacted sorbent. The combustion system and the inclusion of other fuels may also affect the chemical composition, physical properties and leaching behavior. The alkalinity of the FBC material, residual lime and pozzolanic properties are desirable characteristics for use in soil stabilization and mine reclamation. At reclaimed surface coal mines, placement of CCP is intended to reduce the amount of acid mine drainage (AMD) produced at such sites. Neutralization, inhibition of acid forming bacteria, encapsulation of the pyrite or water diversion are believed to be the mechanisms facilitated by the alkaline material. Comparison of water quality, before and after injection of a grout composed of FBC ash and water indicated small increases in pH and decreases in acidity at discharge points. The concentrations of calcium and magnesium in water samples generally increased compared to background levels. The average concentration of trace elements (arsenic, cobalt, copper, nickel and zinc) was slightly elevated in the injection areas, but in down dip and discharge water samples were comparable to background levels. Over a four year period, the average acidity in the injected area decreased by approximately 30%, a value similar to another site where a mixture of class F fly ash and cement was injected. Although coal mine remediation is a beneficial environmental use of FBC products, its effectiveness may be related to the amount of FBCB used and the method of emplacement.

    Balancing productivity, profitability, and environmental health is a key challenge for agricultural sustainability. Most crop production systems in the United States are characterized by low species and management diversity, high use of fossil energy and agrichemicals, and large negative impacts on the environment. We hypothesized that cropping system diversification would promote ecosystem services that would supplement, and eventually displace, synthetic external inputs used to maintain crop productivity. To test this, we conducted a field study from 2003–2011 in Iowa that included three contrasting systems varying in length of crop sequence and inputs. We compared a conventionally managed 2-yr rotation (maize-soybean) that received fertilizers and herbicides at rates comparable to those used on nearby farms with two more diverse cropping systems: a 3-yr rotation (maize-soybean-small grain + red clover) and a 4-yr rotation (maize-soybean-small grain + alfalfa-alfalfa) managed with lower synthetic N fertilizer and herbicide inputs and periodic applications of cattle manure. Grain yields, mass of harvested products, and profit in the more diverse systems were similar to, or greater than, those in the conventional system, despite reductions of agrichemical inputs. Weeds were suppressed effectively in all systems, but freshwater toxicity of the more diverse systems was two orders of magnitude lower than in the conventional system. Results of our study indicate that more diverse cropping systems can use small amounts of synthetic agrichemical inputs as powerful tools with which to tune, rather than drive, agroecosystem performance, while meeting or exceeding the performance of less diverse systems.

    Full Text Available The intention to purchase green products is the tendency of a person who prefers to purchase a product with optimal environmental characteristics rather than usual products. Nowadays, the environment is very important and maintaining it is a vital issue for all groups of people, whether in the customer's position or in the distributor’s position. However, in spite of the increased environmental awareness among consumers and encouragements made by producers for them to buy green products, we require further investigation in this area in order to increase green purchasing among different group of people. The main objective of this study is to investigate the impact of the environmental attitude on the decision to purchase a green product with the mediating role of environmental concerns and care for green products. This research is an applied research, and correlational-descriptive in terms of data analysis. The research population includes consumers from Bushehr city, sampled based on availability. In this research, 300 questionnaires were distributed among consumers. Structural equation modeling was used to analyze the data. The findings of this research showed that the environmental attitude of customers has significant and positive impact on caring for green products and environmental concerns. In addition, environmental concerns and care for green products have a significant and positive impact on green purchasing decision.

    The extensive use of β-lactam antibiotics has led to emergence and spread of extended-spectrum β-lactamases (ESBLs). This study was conducted to investigate the prevalence of 7 different ESBL genes (bla TEM , bla SHV , bla CTX-M , bla VEB , bla PER , bla GES , and bla OXA-10 ) and O25b-ST131 high-risk clone among 61 clinical isolates of Escherichia coli. Also, one broad-spectrum β-lactamase (bla OXA-1 ) was investigated. This study was also constructed to evaluate iodometric overlay method in detection of ESBL production. Phenotypic identification of E. coli isolates using API 20E revealed 18 distinct biotypes. DNA fingerprinting using enterobacterial repetitive intergenic consensus polymerase chain reaction (ERIC-PCR) differentiated all isolates into 2 main phylogenetic groups with 60 distinct genetic profiles. Elevated values of minimal inhibitory concentration (MIC) 50 and MIC 90 for third- and fourth-generation cephalosporins were observed. Phenotypic tests revealed that 85.24% of isolates were ESBL producers. The incidence rates of bla TEM , bla SHV , bla CTX-M , bla GES , bla OXA-1 , and bla OXA-10 among E. coli ESBL producer phenotype were 69.23%, 25%, 96.15%, 3.85%, 11.54%, and 48%, respectively. On the other hand, bla VEB and bla PER were not detected. Sequencing of bla TEM and bla SHV revealed that bla TEM-214 and bla SHV-11 were the most prevalent variants. Group characterization of bla CTX-M revealed that bla CTX-M-1 was the most prevalent group of bla CTX-M family. It was found that 30.77% of E. coli ESBL producers belonged to O25b-ST131 clone harboring bla CTX-M-15 . This study concluded that iodometric overlay method was 100% sensitive in detection of ESBL production. To our knowledge, this is the first Egyptian study that declares the emergence of E. coli O25b-ST131 harboring bla GES .

    This paper presents a study focusing on the environmental impacts of foamed concrete production and exploitation. CO2 emissions are very important factor for describing durability and sustainability of any building material and its life cycle. The building sector is one of the largest energy-consuming sectors in the world. In this study CO2 emissions are evaluated with regard to three types of energy resources (gas, coal and eco-friendly fuel). The related savings on raw materials are up to 120 t of water per 1000 t of traditionally mixed foamed concrete and up to 350 t of sand per 1000 t of foamed concrete produced with intensive mixing technology. In addition, total reduction of CO2 emissions (up to 60 t per 1000 m3 of material) and total energy saving from introduction of foamed concrete production (depending on the type of fuel) were calculated. In order to analyze the conditions of exploitation, both thermal conductivity and thickness of wall was determined. All obtained and calculated results were compared to those of the commercially produced autoclaved aerated concrete.

    The Programmatic Environmental Impact Statement for Tritium Supply and Recycling considers several methods for the production of tritium. One of these methods is the Accelerator Production of Tritium. This report summarizes the design characteristics of APT including the accelerator, target/blanket, tritium extraction facility, and the balance of plant. Two spallation targets are considered: (1) a tungsten neutron-source target and (2) a lead neutron-source target. In the tungsten target concept, the neutrons are captured by the circulating He-3, thus producing tritium; in the lead target concept, the tritium is produced by neutron capture by Li-6 in a surrounding lithium-aluminum blanket. This report also provides information to support the PEIS including construction and operational resource needs, waste generation, and potential routine and accidental releases of radioactive material. The focus of the report is on the impacts of a facility that will produce 3/8th of the baseline goal of tritium. However, some information is provided on the impacts of APT facilities that would produce smaller quantities

    Landslides are one of the most destructive natural hazard that causes damages to urban area worldwide. The knowledge of where a landslide could occur is essential for the strategic management of the territory and for a good urban planning . In this contest landslide susceptibility zoning (LSZ) is crucial to provide information on the degree to which an area can be affected by future slope movements. Despite landslide susceptibility maps have been prepared extensively during the last decades, there are few examples of application is in the environmental plans (EP). In this work we present a proposal for the integration of the landslide inventory map with the following landslide susceptibility products: (i) landslide susceptibility zonation , (ii) the associated error map and (iii) the susceptibility uncertainty map. Moreover we proposed to incorporate detailed morphological studies for the evaluation of landslide risk associated to local parceling plan. The integration of all this information is crucial for the management of landslide risk in urban expansions forecasts. Municipality, province and regional administration are often not able to support the costs of landslide risk evaluation for extensive areas but should concentrate their financial resources to specific hazardous and unsafe situations defined by the result of the integration of landslide susceptibility products. Zonation and detail morphological analysis should be performed taking into account the existing laws and regulations, and could become a starting point to discuss new regulations for the landslide risk management.

    The growth of China's industry has been seriously depending on energy and environment. This paper attempts to apply the directional distance function and the Luenberger productivity index to measure the environmental efficiency, environmental total factor productivity, and its components at the level of subindustry in China over the period from 1999 to 2009 while considering energy consumption and emission of pollutants. This paper also empirically examines the determinants of efficiency and productivity change. The major findings are as follows. Firstly, the main sources of environmental inefficiency of China's industry are the inefficiency of gross industrial output value, the excessive energy consumption, and pollutant emissions. Secondly, the highest growth rate of environmental total factor productivity among the three industrial categories is manufacturing, followed by mining, and production and supply of electricity, gas, and water. Thirdly, foreign direct investment, capital-labor ratio, ownership structure, energy consumption structure, and environmental regulation have varying degrees of effects on the environmental efficiency and environmental total factor productivity.

    Environmental protection is a major issue throughout the world. Effective environmental protection techniques exist that are simple, creative, practical, and often cost effective. The cornerstone of cost effective environmental protection is an environmental management system. Various techniques are also available for reducing wastes, minimizing spills, remediating soils, reducing air emissions, and protecting groundwater and surface water in exploration and production operations

  8. Using Remote Sensing Products for Environmental Analysis in South America

    Full Text Available Land cover plays a major role in many biogeochemical models that represent processes and connections with terrestrial systems; hence, it is a key component for public decisions in ecosystems management. The advance of remote sensing technology, combined with the emergence of new operational products, offers alternatives to improve the accuracy of environmental monitoring and analysis. This work uses the GLOBCOVER, the Vegetation Continuous Field (VCF, MODIS Fire Radiative Power (FRP and the Tropical Rainfall Measuring Mission (TRMM remotely sensed databases to analyze the biomass burning distribution, the land use and land cover characteristics and the percent of tree cover in South America during the years 2000 to 2005. Initially, GLOBCOVER was assessed based on VCF product, and subsequently used for quantitative analysis of the spatial distribution of the South America fires with the fire radiative power (FRP. The results show that GLOBCOVER has a tendency to overestimate forest classes and to underestimate urban and mangroves areas. The fire quantification based on GLOBCOVER product shows that the highest incidence of fires can be observed in the arc of deforestation, located in the Amazon forest border, with vegetation cover composed mainly of broadleaved evergreen or semi-deciduous forest. A time series analysis of FRP database indicates that biomass burning occurs mainly in areas of broadleaved evergreen or semi-deciduous forest and in Brazilian Cerrado associated with grassland management, agricultural land clearing and with the deforestation of Amazon tropical rainforest. Also, variations in FRP intensity and spread can be attributed to rainfall anomalies, such as in 2004, when South America had a positive anomaly rainfall.

    2014-12-01

    This presentation discusses two ongoing interdisciplinary case studies that are using qualitative research to design and enhance environmental communication and science products for outreach and decision making purposes. Both cases demonstrate the viability and practical value of qualitative social science methodology, specifically focus group interviews, to better understand the viewpoints of target audiences, improve deliverables, and support project goals. The first case is a NOAA-funded project to conduct process-based modeling to project impact from climate change in general and sea level rise in particular to the natural and built environment. The project spans the Mississippi, Alabama, and Florida Panhandle coasts with concentration on the three National Estuarine Research Reserves. As part of the broader project, four annual focus groups were conducted with a purposive sample of coastal resource managers to capture their perspectives and suggestions to better meet their informational and operational needs. The second case is a Florida Sea Grant-funded project that is developing, implementing, and testing a cohesive outreach campaign to promote voluntary careful and responsible recreational boating to help protect sensitive marine life and habitats (especially seagrasses and oyster reefs) in the Mosquito Lagoon. Six focus groups were conducted with a purposive sample of the target audience of boaters to gain insights, feedback, and ideas on the direction of the campaign and design of the messages and products. The campaign materials created include a branded website, Facebook page, mobile app, information packets, brochures, pledge forms, and promotional items. A comparison of these two case studies will be provided and will explain how the qualitative findings were/are being implemented to tailor and refine the respective communication strategies and techniques including the emerging outreach products. The resulting outcomes are messages and tools that are

    TESPI (Tool for Environmental Sound Product Innovation) is the prototype of a software tool developed within the framework of the "eLCA" project. The project, (www.elca.enea.it)financed by the European Commission, is realising "On line green tools and services for Small and Medium sized Enterprises (SMEs)". The implementation by SMEs of environmental product innovation (as fostered by the European Integrated Product Policy, IPP) needs specific adaptation to their economic model, their knowledge of production and management processes and their relationships with innovation and the environment. In particular, quality and costs are the main driving forces of innovation in European SMEs, and well known barriers exist to the adoption of an environmental approach in the product design. Starting from these considerations, the TESPI tool has been developed to support the first steps of product design taking into account both the quality and the environment. Two main issues have been considered: (i) classic Quality Function Deployment (QFD) can hardly be proposed to SMEs; (ii) the environmental aspects of the product life cycle need to be integrated with the quality approach. TESPI is a user friendly web-based tool, has a training approach and applies to modular products. Users are guided through the investigation of the quality aspects of their product (customer"s needs and requirements fulfilment) and the identification of the key environmental aspects in the product"s life cycle. A simplified check list allows analyzing the environmental performance of the product. Help is available for a better understanding of the analysis criteria. As a result, the significant aspects for the redesign of the product are identified.

    2010-01-01

    Based on the analysis of shifting direction of radionuclide in production process and the environmental investigation and monitoring, the radioactive environmental impact from a production project of titanium dioxide by chlorination process has been analyzed and assessed. The result of radioactive environmental investigation shows that values of assessment factors are in the range of environmental radioactive background. The radioactive environmental sensitive spot has been delineated. The results of radioactive environmental prediction show that the additional doses to workers and residents are 0.59 mSv/a and 9.28 × 10-4 mSv/a respectively which are less than the annual dose limits of administration. The radioactive environmental impact of the production project of the titanium dioxide by chlorination process will meet the needs of national regulations and standards if radiation protection and environmental protection measures are implemented and radioactive environmental monitoring are strengthened.

    Full Text Available Silver is a known disinfectant from ancient times, and it has been widely used for various purposes: for food and water disinfection, curing of wounds and as a universal antibiotic for a wide spectrum of diseases - until the Second World War and the discovery of penicillin. Until recently, it was assumed that silver, being a heavy metal, was toxic for humans and living beings. However, the newest research provides facts that the usage of silver, even for drinking water disinfection, is benign if it is added in small concentrations (in parts per billion. It has been shown in the newer scientific and technical literature that silver in colloidal form is a powerful (secondary disinfectant for drinking water, that it can be effectively used for the disinfection of water containers including swimming pools, installations in food industry, medicine, etc. Particularly, it has been shown that colloidal silver combined with hydrogen peroxide shows synergism having strong bactericidal and antiviral effects. The combination can be successfully used as a disinfectant in agriculture, food production and medicine. The original electrochemical process of production, the mechanism of physical-chemical reactions in that process and the mechanism of the antiseptic affect of the environmentally friendly disinfectant, based on the synergism of colloidal silver and hydrogen peroxide and the activity of electrochemically activated water, is shown. The starting solution was anolyte, obtained in electrochemical activation by water electrolysis of a highly diluted solution of K-tartarate in demineralized water (5.5-1CT4 M. The problem of electrolysis of very dilute aqueous solutions in membrane cells was particularly treated. It was shown that the efficiency of the electrolysis depends on the competition between the two processes: the rates of the processes of hydrogen and oxygen generation at the electrodes and the process of diffusion of hydrogen and hydroxyl ions

    Full Text Available We assessed the environmental, economic, and social impacts of the process for producing cellulose nanofibers (CNFs, which are considered to be a valuable sustainable woody biomass feedstock. The greenhouse gas (GHG emissions associated with CNF production are greater than the emissions associated with producing most plastic materials used in vehicle components because the grinding process during CNF production generates significant GHG emissions. The cost of CNF production is also higher than the cost of producing comparable plastics for automotive use because of the high cost of the pulverization process. The sensitivity analysis in this study suggested that GHG emissions and manufacturing costs could be reduced by 19.1–76.4% and 3.6–12.2%, respectively, by improving the energy efficiency of CNF production by two to five times. We compared the potential social risks associated with CNF production between Japan and Vietnam using a product social impact life cycle assessment database. It is desirable to reduce the social risk on the fair salary and child labor, and to improve the safe and healthy living conditions in the local communities that import wood chips harvested in Vietnam.

    Tonini, D.

    2013-02-15

    To evaluate the environmental and energy performance of bioenergy and waste-to-energy systems life cycle assessment was used in this thesis. This was supported by other tools such as material, substance, energy flow analysis and energy system analysis. The primary objective of this research was to provide a consistent framework for the environmental assessment of innovative bioenergy and waste-to-energy systems including the integration of LCA with other tools (mentioned earlier). The focus was on the following aspects: - Evaluation of potential future energy scenarios for Denmark. This was done by integrating the results of energy system analysis into life cycle assessment scenarios. - Identification of the criticalities of bioenergy systems, particularly in relation to land use changes. - Identification of potentials and criticalities associated with innovative waste refinery technologies. This was done by assessing a specific pilot-plant operated in Copenhagen, Denmark. The waste refining treatment was compared with a number of different state-of-the-art technologies such as incineration, mechanical-biological treatment and landfilling in bioreactor. The results highlighted that production of liquid and solid biofuels from energy crops should be limited when inducing indirect land use changes (iLUC). Solid biofuels for use in combined heat and power plants may perform better than liquid biofuels due to higher energy conversion efficiencies. The iLUC impacts stood out as the most important contributor to the induced GHG emissions within bioenergy systems. Although quantification of these impacts is associated with high uncertainty, an increasing number of studies are documenting the significance of the iLUC impacts in the bioenergy life cycle. With respect to municipal solid waste, state of the art incineration, MBT and waste refining (with associated energy and material recovery processes) may all provide important and comparable GHG emission savings.

    Analysis of biomass fuel conversion options for biogas production at Appolonia in Ghana has demonstrated that the technique is promising not only for solving some of the country's energy and agricultural problems, but as a very useful way of waste treatment which should help improve waste management. Some environmental analyses were made and some of the preliminary results obtained are presented and discussed. There has been considerable decrease in both biochemical oxygen demand and biological oxygen demand of the effluents compared with the corresponding values obtained for the influents of the three most readily available biomass sources used - human faeces, cow dung and pig dung. Apart from methane (about 54%) and carbon dioxide (about 40%) the biogas produced at Appolonia , according to investigations, using a gas filter analyser and gas chromatography, was found to contain from 1 to 2% hydrogen sulphide which is poisonous. Two other components were detected in the gas but not identified in this present work. (author). 2 figs., 5 tabs., 8 refs

  7. Procedural learning during declarative control.

    Science.gov (United States)

    Crossley, Matthew J; Ashby, F Gregory

    2015-09-01

    There is now abundant evidence that human learning and memory are governed by multiple systems. As a result, research is now turning to the next question of how these putative systems interact. For instance, how is overall control of behavior coordinated, and does learning occur independently within systems regardless of what system is in control? Behavioral, neuroimaging, and neuroscience data are somewhat mixed with respect to these questions. Human neuroimaging and animal lesion studies suggest independent learning and are mostly agnostic with respect to control. Human behavioral studies suggest active inhibition of behavioral output but have little to say regarding learning. The results of two perceptual category-learning experiments are described that strongly suggest that procedural learning does occur while the explicit system is in control of behavior and that this learning might be just as good as if the procedural system was controlling the response. These results are consistent with the idea that declarative memory systems inhibit the ability of the procedural system to access motor output systems but do not prevent procedural learning.

    2016-10-01

    Food production and consumption have major impacts on the environment. At the same time, changes in human diets worldwide are increasingly leading to health problems. Both issues are highly influenced by consumers' everyday food choices and could be addressed by reducing consumption of meat and other animal products. To promote sustainable food consumption, we need to know how consumers perceive the environmental friendliness and healthiness of food products, on which criteria they base their evaluations of environmental friendliness and healthiness, and how their estimations relate to life cycle assessments and nutrient profiling. We presented 30 protein products, which varied in provenance, production methods, and processing, to 85 participants from Switzerland. They were asked to sort the products once according to their perceived environmental friendliness and once according to their perceived healthiness. The mean distances between the products were compared to the products' life cycle assessments and nutrient profiles. The results showed that perceived environmental friendliness and healthiness are highly correlated. The main predictors of the products' perceived environmental friendliness were product category, presence of an organic label, and provenance; and for perceived healthiness, these predictors were product category, fat content, processing, and presence of an organic label. Environmental friendliness and healthiness estimations were significantly correlated to the life cycle assessments and the nutrient profiles of the products, respectively. Hence, to promote healthy and environmentally friendly food choices, motivators related to environmental friendliness and healthiness could be used in synergy. Awareness about meat's environmental impact should be increased and better information is needed for consumers to make an accurate environmental impact and healthiness assessments of protein products.

  9. Schizophrenia patients demonstrate a dissociation on declarative and non-declarative memory tests.

    Science.gov (United States)

    Perry, W; Light, G A; Davis, H; Braff, D L

    2000-12-15

    Declarative memory refers to the recall and recognition of factual information. In contrast, non-declarative memory entails a facilitation of memory based on prior exposure and is typically assessed with priming and perceptual-motor sequencing tasks. In this study, schizophrenia patients were compared to normal comparison subjects on two computerized memory tasks: the Word-stem Priming Test (n=30) and the Pattern Sequence Learning Test (n=20). Word-stem Priming includes recall, recognition (declarative) and priming (non-declarative) components of memory. The schizophrenia patients demonstrated an impaired performance on recall of words with relative improvement during the recognition portion of the test. Furthermore, they performed normally on the priming portion of the test. Thus, on tests of declarative memory, the patients had retrieval deficits with intact performance on the non-declarative memory component. The Pattern Sequence Learning Test utilizes a serial reaction time paradigm to assess non-declarative memory. The schizophrenia patients' serial reaction time was significantly slower than that of comparison subjects. However, the patients' rate of acquisition was not different from the normal comparison group. The data suggest that patients with schizophrenia process more slowly than normal, but have an intact non-declarative memory. The schizophrenia patients' dissociation on declarative vs. non-declarative memory tests is discussed in terms of possible underlying structural impairment.

    2005-01-01

    Irrigation supplies at proper time and adequate quantities are imperative for potential agricultural production under arid and semi-arid climatic conditions. To achieve this goal one of the largest integrated irrigation network was established. Without adequate drainage it resulted in the problems of water logging and salinity. To control these problems a big programme of Salinity Control and Reclamation projects (SCARPs) was initiated during 1960 and 82 such SCARPs have been completed and 9 were in progress up to June, 2002 covering an area of 18.6 ma (7.5 mh) at a cost of Rs.93 billions. Under these projects 12746 tube wells in fresh, 3572 in saline groundwater and 13726 km surface and 12612 km tile pipes covering 6391.7 ha, 160 km interceptor drains have been constructed an area of 0.998 ma (GCA). In addition to this some other measures like on farm water management, canal command project, canal lining, construction of evaporation ponds, establishment of research Inst./Organizations were also taken. Many drainage plans like Master Plan (1963), Northern Regional Plan (1967), Water Sector Investment Plan Study (1990), Right Bank Master Plan (1992), Drainage Sector Environmental Assessment (1993) and National Drainage Programme (1995) were prepared and implemented. The cost of the, phase-I of the National Drainage Programme was 785 million US$. The main activities undertaken were remodeling/extension of existing surface and new drains; rehabilitation/replacement of saline ground water (SGW) tube wells; construction of interceptor drains, reclamation of waterlogged areas through biological drainage and transfer of fresh ground water tube wells to the farmers. The data indicate that all the measures taken have played a significant role in reducing the water logging, salinity/sodicity and have increased the crop production and consequently improved the socio-economic conditions of the peoples especially the farming community. The environment in these areas was also

    The Ecuadorian portion of the Amazon Basin, known locally as the Oriente, is the major oil producing region in Ecuador. The tropical rain forests of the Oriente contain some of the Earth's most biologically diverse and ecologically sensitive areas. In addition, the rain forest is home to several groups of indigenous peoples.When formulating an exploration plan and prior to beginning E and P activities in the Oriente, operators must understand the environmental and sociocultural issues in the region. These concerns are considered throughout the planning process, from project conception to project closure. An environmental management plan is adopted which addresses environmental and sociocultural concerns, minimizes environmental impact, prevents delays, and limits environmental liability

  17. Bridging environmental and financial cost of dairy production: A case study of Irish agricultural policy.

    2018-02-15

    The Irish agricultural policy 'Food Harvest 2020' is a roadmap for sectoral expansion and Irish dairy farming is expected to intensify, which could influence the environmental and economic performance of Irish milk production. Evaluating the total environmental impacts and the real cost of Irish milk production is a key step towards understanding the possibility of sustainable production. This paper addresses two main issues: aggregation of environmental impacts of Irish milk production by monetization, to understand the real cost of Irish milk production, including the environmental costs; and the effect of the agricultural policy 'Food Harvest 2020' on total cost (combining financial cost and environmental cost) of Irish milk production. This study used 2013 Irish dairy farming as a baseline, and defined 'bottom', 'target' and 'optimum' scenarios, according to the change of elementary inputs required to meet agricultural policy ambitions. The study demonstrated that the three monetization methods, Stepwise 2006, Eco-cost 2012 and EPS 2000, could be used for aggregating different environmental impacts into monetary unit, and to provide an insight for evaluating policy related to total environmental performance. The results showed that the total environmental cost of Irish milk production could be greater than the financial cost (up to €0.53/kg energy corrected milk). The dairy expansion policy with improved herbage utilization and fertilizer application could reduce financial cost and minimize the total environmental cost of per unit milk produced.

    Full Text Available Reward prediction errors (RPEs are thought to drive learning. This has been established in procedural learning (e.g., classical and operant conditioning. However, empirical evidence on whether RPEs drive declarative learning-a quintessentially human form of learning-remains surprisingly absent. We therefore coupled RPEs to the acquisition of Dutch-Swahili word pairs in a declarative learning paradigm. Signed RPEs (SRPEs; "better-than-expected" signals during declarative learning improved recognition in a follow-up test, with increasingly positive RPEs leading to better recognition. In addition, classic declarative memory mechanisms such as time-on-task failed to explain recognition performance. The beneficial effect of SRPEs on recognition was subsequently affirmed in a replication study with visual stimuli.

    2001-01-01

    The Helsinki Declaration is a crucial ethical landmark for clinical research involving human beings. Since the Declaration was issued, a series of revisions and modifications have been introduced into the original text, but they have not altered its humanist approach or its international force for regulating clinical research. A proposal for an extensive revision of the Declaration's underlying ethical principles has been debated for the past four years. If the proposal is approved, international clinical research involving human beings will be modified, further increasing the vulnerability of certain social groups. This article discusses the historical process involved in passing the Helsinki Declaration and the most recent debate on the new draft. The article analyzes the new text's social implications for underdeveloped countries, arguing for a political approach to the vulnerability concept.

    The livestock sector has a major impact on the environment. This environmental impact may be reduced by feeding agricultural co-products (e.g. beet tails) to livestock, as this transforms inedible products for humans into edible products, e.g. pork or beef. Nevertheless, co-products have different

    Current negotiations at the WTO’s Committee on Trade and Environment have made it conceivable that WTO members agree on selective tariff cuts for certain Environmentally Preferable Products, in an attempt to combine gains from trade and from cleaner production/consumption. This raises questions on the environmental and welfare implications of trade policy when a close substitute (“environmentally worse") exists. Using a simple partial equilibrium model with two substitutable goods ('green' an...

  6. Assessment of Environmental Stresses for Enhanced Microalgal Biofuel Production – An Overview

    International Nuclear Information System (INIS)

    Cheng, Dan; He, Qingfang

    2014-01-01

    Microalgal biofuels are currently considered to be the most promising alternative to future renewable energy source. Microalgae have great potential to produce various biofuels, including biodiesel, bioethanol, biomethane, and biohydrogen. Cultivation of biofuel-producing microalgae demands favorable environmental conditions, such as suitable light, temperature, nutrients, salinity, and pH. However, these conditions are not always compatible with the conditions beneficial to biofuel production, because biofuel-related compounds (such as lipids and carbohydrates) tend to accumulate under environmental-stress conditions of light, temperature, nutrient, and salt. This paper presents a brief overview of the effects of environmental conditions on production of microalgal biomass and biofuel, with specific emphasis on how to utilize environmental stresses to improve biofuel productivity. The potential avenues of reaping the benefits of enhanced biofuel production by environmental stresses while maintaining high yields of biomass production have been discussed.

    The environmental catastrophic accidents in China over the last three decades have triggered implementation of myriad policies by the government to help abate environmental pollution in the country. Consequently, research into environmental pollution liability insurance and how that can stimulate economic growth and the development of financial market in China is worthwhile. This study attempts to design a financial derivative for China's environmental pollution liability insurance to offer strong financial support for significant compensation towards potential catastrophic environmental loss exposures, especially losses from the chemical industry. Assuming the risk-free interest rate is 4%, the market portfolio expected return is 12%; the financial asset beta coefficient is 0.5, by using the capital asset pricing model (CAPM) and cash flow analysis; the principal risk bond yields 9.4%, single-period and two-period prices are 103.85 and 111.58, respectively; the principal partial-risk bond yields 10.09%, single-period and two-period prices are 103.85 and 111.58, respectively; and the principal risk-free bond yields 8.94%, single-period and two-period prices are 107.99 and 115.83, respectively. This loss exposure transfer framework transfers the catastrophic risks of environmental pollution from the traditional insurance and reinsurance markets to the capital market. This strengthens the underwriting capacity of environmental pollution liability insurance companies, mitigates the compensation risks of insurers and reinsurers, and provides a new channel to transfer the risks of environmental pollution.

    Highlights: • Anaerobic monodigestion and codigestion were compared. • The environmental advantages of suitable waste management were proved. • The use of cereal crops as feedstock improves biogas yield. • Cultivation step implies the most important environmental hotspot. • Digestate management options were evaluated. - Abstract: The aim of this study was to assess the environmental profile of a bioenergy system based on a co-digestion plant using maize silage and pig slurry as substrates. All the processes involved in the production of bioenergy as well as the avoided processes accrued from the biogas production system were evaluated. The results evidenced the environmental importance of the cultivation step and the environmental credits associated to the avoided processes. In addition, this plant was compared with two different plants that digest both substrates separately. The results revealed the environmental benefits of the utilisation of pig slurry due to the absence of environmental burdens associated with its production as well as credits provided when avoiding its conventional management. The results also presented the environmental drawbacks of the utilisation of maize silage due to the environmental burdens related with its production. Accordingly, the anaerobic mono-digestion of maize silage achieved the worst results. The co-digestion of both substrates was ranked in an intermediate position. Additionally, three possible digestate management options were assessed. The results showed the beneficial effect of digestate application as an organic fertiliser, principally on account of environmental credits due to avoided mineral fertilisation. However, digestate application involves important acidifying and eutrophicating emissions

    Full Text Available The environmental issue has been discussed sharply in the organizational environment, as consumers, and society in general, have been increasingly concerned about the environment. In this sense, the companies, especially the factories, seek to minimize the environmental impact caused by its production processes through actions that combine the organization's economic interests with environmental concerns. Thus, this article aims to analyze how environmental management of the productive sector is being carried out at Industria Beta Chapecó/SC. Therefore, we developed a qualitative and descriptive research in order to apply the Model for Environmental Assessment of Industrial Production Systems (MAASPI in the production of Industria Beta sector. The results showed the main environmental interventions caused by the production process of the organization, particularly the interventions for the consumption of electricity, plant location and chip storage. As main proposals to minimize negative environmental impacts, we have the installation of translucent tiles in the production environment, a study on energy efficiency, construction of water and soil testing, construction of waste storage terminals and implementation of the pre-selection of the raw material. The realization of the suggested adjustments enables Industria Beta to foresee the legal environmental requirements, to aim for enviromental certifications and seals and to strengthen its image as environment-friendly with collaborators and society in general.

    Louise Laumann Kjaer

    2015-08-01

    Full Text Available An increasing number of companies are expanding their environmental impact reduction targets and strategies to include their supply chains or whole product life cycles. In this paper, we demonstrate and evaluate an approach, where we used a hybrid Environmental Input-Output (EIO database as a basis for corporate and product environmental footprint accounts, including the entire supply chain. We present three cases, where this approach was applied. Case study 1 describes the creation of total corporate carbon footprint accounts for three Danish regional healthcare organisations. In case study 2, the approach was used as basis for an Environmental Profit and Loss account for the healthcare company, Novo Nordisk A/S. Case study 3 used the approach for life cycle assessment of a tanker ship. We conclude that EIO-based analyses offer a holistic view of environmental performance, provide a foundation for decision-making within reasonable time and cost, and for companies with a large upstream environmental footprint, the analysis supports advancing their sustainability agenda to include supply chain impacts. However, there are implications when going from screening to implementing the results, including how to measure and monitor the effect of the different actions. Thus, future research should include more detailed models to support decision-making.

This investigation is based on the Argumention Theory in the Language proposed by Ducrot (1988,1987. We also used the studies about Discursive Modalization proposed by Koch (2002, Castilho e Castilho (1993, Nascimento (2005, among others. Modalization is considered here as a semantic argumentative strategy, as it enables the speaker to make a statement or to express a point of view about the content of his/her enunciation, according to the interlocution. This study about the previously mentioned gender is qualitative, quantitative and descriptive. The corpus used is composed of 20 (twenty Letters of Declaration issued by different organizations or private and public institutions. We perceived that in the Letters of Declaration analysed argumentation is achieved by the use of modalizers and argumentative operators, used by the speaker to produce different effects of meaning in the texts.

    Full Text Available Tropical deforestation and forest degradation are serious problems for the global environment; as a result, sustainable forest management and forest certification have become important. In this study, using a choice experiment, we investigated, on the demand side, consumers’ preferences and willingness to pay (WTP for certified wood products that attempt to address public concerns regarding deforestation and forest degradation. Specifically, we investigated how estimates of consumers’ preferences and WTP were influenced by product attributes such as quality, certification, and price. To the authors’ knowledge, few studies of this kind have been conducted, particularly in Japan. The study’s main finding was that Japanese consumers were willing to pay a premium for certified wood products with attributes related to sustainable forest management; most preferred were products with attributes related to preserving biodiversity. These findings indicate that consumers are willing to pay a premium for products that contribute to solving the problems of deforestation and forest degradation.

  10. Environmental assessment for the Consumer Products Efficiency Standards program

    Energy Technology Data Exchange (ETDEWEB)

    1980-05-23

    The Energy Policy and Conservation Act of 1975 as amended by the National Energy Conservation Policy Act of 1978, requires the DOE to prescribe energy efficiency standards for thirteen consumer products. The Consumer Products Efficiency Standards (CPES) program covers the following products: refrigerators and refrigerator-freezers; freezers;clothes dryers;water heaters; room air conditioners; home heating equipment (not including furnaces); kitchen ranges and ovens; central air conditioners (cooling and heat pumps); furnaces; dishwashers; television sets; clothes washers; and humidifiers and dehumidifiers. DOE is proposing two sets of standards for all thirteen consumer products: intermediate standards to become effective in 1981 for the first nine products and in 1982 for the second four products, and final standards to become effective in 1986 and 1987, respectively. The final standards are more restrictive than the intermediate standards and will provide manufacturers with the maximum time permitted under the Act to plan and develop extensive new lines of efficient consumer products. The final standards proposed by DOE require the maximum improvements in efficiency which are technologically feasible and economically justified, as required by Section 325(c) of EPCA. The thirteen consumer products account for approximately 90% of all the energy consumed in the nation's residences, or more than 20% of the nation's energy needs. Increases in the energy efficiency of these consumer products can help to narrow the gap between the nation's increasing demand for energy and decreasing supplies of domestic oil and natural gas. Improvements in the efficiency of consumer products can thus help to solve the nation's energy crisis.

    This paper examines how some smart marketers have quickly picked up on the new consumer interest in protecting the environment, turned it into increased sales and profits and at the same time effectively increased energy conservation. They asked their product developers to improve the environmental benefits of their existing products and to design some new ones. Then they asked their advertising writers to put an environmental spin on their product advertising. Next they made frequent visits to the bank with the increased sales revenues from an expanding market share and at the same time are doing something worthwhile in energy and environmental conservation

    The analysis on the economic factor environment and the German environmental industry on international competition is faced to methodological limits, since the environmental industry does not present itself as an homogeneous sector. The study is organized in the following chapters: introduction - the importance of environmental industry; classification of environmental and climate protection industry; productivity volume and production structure; international competition for potential environmental protection products; environmental protection industry and innovative performance. Integrated environmental solutions are of increasing significance, avoiding emissions and products and production process from beginning on. All known forecast indicate an expansive market development. In addition the rising prices for crude oil may push the search for innovative solutions to substitute fossil energy sources. The environmental industry should look for globally transferable solutions in order to promote global sustainable growth.

  15. Left hemisphere EEG coherence in infancy predicts infant declarative pointing and preschool epistemic language.

    Kühn-Popp, N; Kristen, S; Paulus, M; Meinhardt, J; Sodian, B

    2016-01-01

    Pointing plays a central role in preverbal communication. While imperative pointing aims at influencing another person's behavior, declarative gestures serve to convey epistemic information and to share interest in an object. Further, the latter are hypothesized to be a precursor ability of epistemic language. So far, little is known about their underlying brain maturation processes. Therefore, the present study investigated the relation between brain maturation processes and the production of imperative and declarative motives as well as epistemic language in N = 32 infants. EEG coherence scores were measured at 14 months, imperative and declarative point production at 15 months and epistemic language at 48 months. Results of correlational analyses suggest distinct behavioral and neural patterns for imperative and declarative pointing, with declarative pointing being associated with the maturation of the left hemisphere. Further, EEG coherence measures of the left hemisphere at 14 months and declarative pointing at 15 months are related to individual differences in epistemic language skills at 48 months, independently of child IQ. In regression analyses, coherence measures of the left hemisphere prove to be the most important predictor of epistemic language skills. Thus, neural processes of the left hemisphere seem particularly relevant to social communication.

    The bioethanol is playing an increasingly important role in renewable energy in China. Based on the theory of circular economy, integration of different resources by polygeneration is one of the solutions to improve energy efficiency and to reduce environmental impact. In this study, three modes of bioethanol production were selected to evaluate the life cycle energy efficiency and environmental impact of sweet potato-based bioethanol. The results showed that, the net energy ratio was greater than 1 and the value of net energy gain was positive in the three production modes, in which the maximum value appeared in the circular economy mode (CEM). The environment emission mainly occurred to bioethanol conversion unit in the conventional production mode (CPM) and the cogeneration mode (CGM), and eutrophication potential (EP) and global warming potential (GWP) were the most significant environmental impact category. While compared with CPM and CGM, the environmental impact of CEM significantly declined due to increasing recycling, and plant cultivation unit mainly contributed to EP and GWP. And the comprehensive evaluation score of environmental impact decreased by 73.46% and 23.36%. This study showed that CEM was effective in improving energy efficiency, especially in reducing the environmental impact, and it provides a new method for bioethanol production. PMID:28672044

    The growth of China's industry has been seriously depending on energy and environment. This paper attempts to apply the directional distance function and the Luenberger productivity index to measure the environmental efficiency, environmental total factor productivity, and its components at the level of subindustry in China over the period from 1999 to 2009 while considering energy consumption and emission of pollutants. This paper also empirically examines the determinants of efficiency and productivity change. The major findings are as follows. Firstly, the main sources of environmental inefficiency of China's industry are the inefficiency of gross industrial output value, the excessive energy consumption, and pollutant emissions. Secondly, the highest growth rate of environmental total factor productivity among the three industrial categories is manufacturing, followed by mining, and production and supply of electricity, gas, and water. Thirdly, foreign direct investment, capital-labor ratio, ownership structure, energy consumption structure, and environmental regulation have varying degrees of effects on the environmental efficiency and environmental total factor productivity.

    Heer, Jeffrey; Bostock, Michael

    2010-01-01

    We investigate the design of declarative, domain-specific languages for constructing interactive visualizations. By separating specification from execution, declarative languages can simplify development, enable unobtrusive optimization, and support retargeting across platforms. We describe the design of the Protovis specification language and its implementation within an object-oriented, statically-typed programming language (Java). We demonstrate how to support rich visualizations without requiring a toolkit-specific data model and extend Protovis to enable declarative specification of animated transitions. To support cross-platform deployment, we introduce rendering and event-handling infrastructures decoupled from the runtime platform, letting designers retarget visualization specifications (e.g., from desktop to mobile phone) with reduced effort. We also explore optimizations such as runtime compilation of visualization specifications, parallelized execution, and hardware-accelerated rendering. We present benchmark studies measuring the performance gains provided by these optimizations and compare performance to existing Java-based visualization tools, demonstrating scalability improvements exceeding an order of magnitude.

    Material on the environmental concerns associated with offshore drilling and production activities has been synthesized with Department of Fisheries and Environment files on specific projects, these being the primary information source. Recommendations to resolve these concerns have also been provided. Most of the environmental concerns identified in this study are traceable to specific weaknesses in offshore drilling and production procedures and management systems. Hardware weaknesses are seldom of central importance. Areas of concern include the gradual deposition of pollutants from rigs, underwater pipelines and onshore ancillary structures, and the quality of the following: action plans to deal with oil spills, standards for safety and anti-pollution equipment, information provided on the environmental hazards in offshore drilling and production areas, environmental impact assessments, and communication links between those having environmental concerns and expertise (including the public-at-large) and those who make the decisions regarding offshore oil and gas development.

    This paper evaluates environmental policy effects on ligno-cellulosic biomass production and environmental outcomes using an integrated bioeconomic optimization model. The environmental policy integrated climate (EPIC) model is used to simulate crop yields and environmental indicators in current and future potential bioenergy cropping systems based on weather, topographic and soil data. The crop yield and environmental outcome parameters from EPIC are combined with biomass transport costs and economic parameters in a representative farmer profit-maximizing mathematical optimization model. The model is used to predict the impact of alternative policies on biomass production and environmental outcomes. We find that without environmental policy, rising biomass prices initially trigger production of annual crop residues, resulting in increased greenhouse gas emissions, soil erosion, and nutrient losses to surface and ground water. At higher biomass prices, perennial bioenergy crops replace annual crop residues as biomass sources, resulting in lower environmental impacts. Simulations of three environmental policies namely a carbon price, a no-till area subsidy, and a fertilizer tax reveal that only the carbon price policy systematically mitigates environmental impacts. The fertilizer tax is ineffectual and too costly to farmers. The no-till subsidy is effective only at low biomass prices and is too costly to government. - Highlights: ► Bioeconomic optimization model predicts how biomass production affects environment. ► Rising biomass production could impair climate and water quality. ► Environmental protection policies compared as biomass supply grows. ► Carbon price protects the environment cost-effectively as biomass supply expands

    The Integrated Product Policy - IPP - is becoming one of the top priorities for the European Commission within the framework of the product-oriented environmental policies. Rather than a new policy, this is an innovative approach aimed at co-originated existing and forthcoming environmental policies, in order to manage in an integrated way and minimise the impacts connected with the whole product life-cycle. The underlying life-cycle guideline requires the management of each phase by considering what happens in all the other phases. What clearly emerges from a research carried out by Iefe Bocconi is, on the one hand, the effectiveness of co-operation and networking between all the actors involved in the product environmental management within the different phases of its life cycle (policy makers, producers, retailers, consumers, NGOs, etc.) and, on the other, the opportunity of developing an integrated management of both environmental policy instruments and corporate management tools [it

    The main activity of open pit mining of aggregates are aggregates' exploitation of natural mineral deposits and its modification in order to obtain high-quality aggregates. The development of aggregate production is conditioned by a number of factors. The most important are: documented material resources, mining and manufacturing capabilities, the need of environmental protection (environmental aspects), the subordination of the plan of spatial development, formal and legal issues, as well as economic and financial aspects. While identifying and assessing the environmental impacts of manufacturing aggregates one may distinguish those environmental aspects that have or may have the greatest magnitude of the impact on the environment as a result of industrial activities. Manufacturers producing aggregates located in the areas covered by the special environmental protection require extra diligence in the conduct of mining activities for preservation of natural resources. The article discusses some main environmental aspects of the production of construction aggregates on the example of one of the largest producers of this material in Subcarpathian province of Poland. Environmental protection in production of aggregates may refer to four aspects: the use of natural resources, having excluded land from agriculture and forestry, land reclamation after exploitation, and use of energy from renewable energy sources. The economic and environmental impact of production volume of aggregates is evaluated by the index information capacity method and the method of graphs.

    Full Text Available The uses of by-products of cheese industry is still not significant in Brazil, since about 15% of liquid whey is used as raw material in food industry technology. The liquid whey has excellent technological properties, making it an alternative to minimize environmental impacts, besides it enables the use of the same nutritional properties in the production of new food products or adding value to the existing ones. The present study aimed to use liquid whey as an ingredient in the formulation of ice cream, hard candies, ham and breads, as well as to evaluate the influence of it in technological characteristics of the products and to quantify the volume of whey used. In order to evaluate the use of liquid whey, the products were developed with partial or total replacement of milk or water by whey, being the substitution accompanied by the determination of centesimal composition, as well as evaluating the visual characteristics of each product. The results show that the preparation of the products under study with substitution of raw milk or water is viable, proving that using liquid whey is a technological possibility of using a by-product considered to be an environmental pollutant. It was concluded that the use of liquid whey in the food industry reduces the environmental impact, since there is a reduction in the volume of whey discharged into the environment.

    A concept negentropy is introduced to supplement Marx's labor theory of value. The negentropy, that is a less entropy state than the thermal equilibrium state of matter, is a common property of the usefulness of material needs. The production of commodity increases the negentropy of product, but the action raises more environmental entropy than the negentropy of the product. This is environmental damage. In addition the negentropy plays a role of the substance of value and answers the issue about productive and unproductive labor. It is clarified that the origin of surplus value is the negentropy of information

    Full Text Available Furniture industry releases annually a large amount of volatile organic compound to the environment due to the use of adhesives, textiles, paints and coating materials. There are some different methods to measure the load of pollutions and the environmental impacts. Life cycle assessment (LCA is one of the best techniques. LCA is a technique in which all environmental impacts related to a product assessed all over its life cycle, from cradle to grave, and ultimately can be used to improve the production process and to prevent unsuitable environmental impacts. In summary, it can be concluded that the use of this technique is the basis for sustainable development and improving social, economic, and environmental indices. This study focused on the collecting of a comprehensive life cycle inventory data for comfortable furniture in two different production processes (B1 and B2 located in Tehran province, and analyzed the environmental impacts during the production process as gate to gate investigation. The results revealed that emissions in production process B1 were higher than that of production process B2. The reason for this is that basic operations such as sawing and frame assembling along with final operation have been done in the same unit for case B1. Textile production and usage, and polyurethane foam were identified as the main hotspots, respectively. Moreover, the results showed that comfortable furniture production process has the highest effects on ecosystem quality, human health, and resources (fossil fuels and mines, respectively.

    The interest in renewable energy sources has gained great importance in Europe due to the need to reduce fossil energy consumption and greenhouse gas emissions, as required by the Renewable Energy Directive (RED) of the European Parliament. The production of energy from energy crops appears to be consistent with RED. The environmental impact related to this kind of energy primarily originates from crop cultivation. This research aimed to evaluate the environmental impact of different crop systems for biomass production: single and double crop. The environmental performances of maize and maize plus wheat were assessed from a life cycle perspective. Two alternative scenarios considering different yields, crop management, and climatic conditions, were also addressed. One normal cubic metre of potential methane was chosen as a functional unit. Methane potential production data were obtained through lab experimental tests. For both of the crop systems, the factors that have the greatest influence on the overall environmental burden are: fertilizer emissions, diesel fuel emissions, diesel fuel production, and pesticide production. Notwithstanding the greater level of methane potential production, the double crop system appears to have the worse environmental performance with respect to its single crop counterpart. This result is due to the bigger quantity of inputs needed for the double crop system. Therefore, the greater amount of biomass (silage) obtained through the double crop system is less than proportional to the environmental burden that results from the bigger quantity of inputs requested for double crop. - Highlights: • Environmental impact of two crop systems was evaluated • Biomethane specific production tests were carried out • Alternative scenarios (different yields and crop management) were assessed • Maize single crop obtains the better environmental performance • Critical factors are: fertilizer and diesel fuel emissions and diesel fuel

    In order to effectively integrate environmental attributes into the product design and development processes, it is crucial to identify the significant environmental aspects related to a product system within a relatively short period of time. In this study, the usefulness of life cycle assessment (LCA) and a matrix method as tools for identifying the key environmental issues of a product system were examined. For this, a simplified LCA (SLCA) method that can be applied to Electrical and Electronic Equipment (EEE) was developed to efficiently identify their significant environmental aspects for eco-design, since a full scale LCA study is usually very detailed, expensive and time-consuming. The environmentally responsible product assessment (ERPA) method, which is one of the matrix methods, was also analyzed. Then, the usefulness of each method in eco-design processes was evaluated and compared using the case studies of the cellular phone and vacuum cleaner systems. It was found that the SLCA and the ERPA methods provided different information but they complemented each other to some extent. The SLCA method generated more information on the inherent environmental characteristics of a product system so that it might be useful for new design/eco-innovation when developing a completely new product or method where environmental considerations play a major role from the beginning. On the other hand, the ERPA method gave more information on the potential for improving a product so that it could be effectively used in eco-redesign which intends to alleviate environmental impacts of an existing product or process.

  4. Revising psychoanalytic interpretations of the past. An examination of declarative and non-declarative memory processes.

    Science.gov (United States)

    Davis, J T

    2001-06-01

    The author reviews a contemporary cognitive psychology perspective on memory that views memory as being composed of multiple separate systems. Most researchers draw a fundamental distinction between declarative/explicit and non-declarative/implicit forms of memory. Declarative memory is responsible for the conscious recollection of facts and events--what is typically meant by the everyday and the common psychoanalytic use of the word 'memory'. Non-declarative forms of memory, in contrast, are specialised processes that influence experience and behaviour without representing the past in terms of any consciously accessible content. They operate outside of an individual's awareness, but are not repressed or otherwise dynamically unconscious. Using this theoretical framework, the question of how childhood relationship experiences are carried forward from the past to influence the present is examined. It is argued that incorporating a conceptualisation of non-declarative memory processing into psychoanalytic theory is essential. Non-declarative memory processes are capable of forming complex and sophisticated representations of the interpersonal world. These non-declarative memory processes exert a major impact on interpersonal experience and behaviour that needs to be analysed on its own terms and not mistakenly viewed as a form of resistance.

    Full Text Available Healthy sleep is essential in children’s cognitive, behavioral, and emotional development. However, remarkably little is known about the influence of sleep disorders on different memory processes in childhood. Such data could give us a deeper insight into the effect of sleep on the developing brain and memory functions and how the relationship between sleep and memory changes from childhood to adulthood. In the present study we examined the effect of sleep disorder on declarative and non-declarative memory consolidation by testing children with sleep-disordered breathing (SDB which is characterized by disrupted sleep structure. We used a story recall task to measure declarative memory and Alternating Serial Reaction Time (ASRT task to assess non-declarative memory. This task enables us to measure two aspects of non-declarative memory, namely general motor skill learning and sequence-specific learning. There were two sessions: a learning phase and a testing phase, separated by a 12-hour offline period with sleep. Our data showed that children with SDB exhibited a generally lower declarative memory performance both in the learning and testing phase; however, both the SDB and control groups exhibited retention of the previously recalled items after the offline period. Here we showed intact non-declarative consolidation in SDB group in both sequence-specific and general motor skill. These findings suggest that sleep disorders in childhood have a differential effect on different memory processes (online vs. offline and give us insight into how sleep disturbances affects developing brain.

    Full Text Available Ecolabel products are one approach towards environmental sustainability. Ecolabel programs have been socialized by governments all over the world to reduce environmental harm caused by the daily life cycles of the products that citizens use. The present study was aimed at measuring citizens’ behavior intention (BI regarding ecolabel product usage. An extended theory of reasoned action (TRA, namely that of pro-environmental reasoned action (PERA, is used as the predictor model. A total of 213 questionnaire data, collected from citizens of Indonesia, was analyzed using structural equation modeling. The analysis results show that the PERA model is able to describe 68% of citizens’ BI regarding ecolabel product usage. The analysis results also reveal that attitude is a key determinant factor. Several practical suggestions based on the results can be used as input for policy makers and company management to consider in their efforts to increase citizens’ BI to use ecolabel products.

  12. International recommendations for managing environmental risk from nuclear energy production

    Clarke, R.H.

    1996-01-01

    The establishment of any recommendations relating to the control of radiation exposure requires decisions on the management of the associated risk. Those decisions must reflect attitudes towards the acceptable levels of risk for both workers and the public. The environmental impact of nuclear energy principally concerns radiation doses and risks to members of the public. The author shows how the considerations of risk and acceptability are used internationally to set standards for protection. The results differ as between limiting doses for normal operations, for restricting the likelihood of accidents, intervening after an accident, or reducing doses from a chronic exposure situation. It is concluded that there is a coherent pattern in the resulting protection system

    2008-07-01

    A variety of test methods were used to study the gradation, bioaccumulation, and toxicity of nicotine. Studies included determination of the octanol-water partition coefficient, conversion to CO2 in soil and activated sludge, and evaluation of the effects on microbiological and algal inhibition as well as plant germination and root elongation. The partitioning of nicotine between octanol and water indicated that nicotine will not bioaccumulate regardless of the pH of the medium. The aqueous and soil-based biodegradation studies indicated that nicotine is readily biodegradable in both types of media. The microbiological inhibition and aquatic and terrestrial toxicity tests indicated that nicotine has low toxicity. The U.S. Environmental Protection Agency Persistence, Bioaccumulation, and Toxicity Profiler model, based on the structure of nicotine and the predictive rates of hydroxyl radical and ozone reactions, estimated an atmospheric half-life of less than 5.0 h. Using this value in the Canadian Environmental Modeling Center level III model, the half-life of nicotine was estimated as 3.0 d in water and 0.5 d in soil. This model also estimated nicotine discharge into the environment; nicotine would be expected to be found predominantly in water (93%), followed by soil (4%), air (3%), and sediment (0.4%). Using the estimated nicotine concentrations in water, soil, and sediment and the proper median effective concentrations derived from the algal growth, biomass inhibition, and buttercrunch lettuce (Lactuca sativa) seed germination and root elongation studies, hazard quotients of between 10(-7) and 10(-8) were calculated, providing further support for the conclusion that the potential for nicotine toxicity to aquatic and terrestrial species in the environment is extremely low.

  5. Suppression of bremsstrahlung and pair production due to environmental factors

    International Nuclear Information System (INIS)

    Klein, Spencer

    1999-01-01

    The environment in which bremsstrahlung and pair creation occurs can strongly affect cross sections for these processes. Because ultrarelativistic electromagnetic interactions involve very small longitudinal momentum transfers, the reactions occur gradually, spread over long distances. During this time, even relatively weak factors can accumulate enough to disrupt the interaction. In the Landau-Pomeranchuk-Migdal effect, multiple scattering reduces the bremsstrahlung and pair production cross section. This review will discuss this and a variety of other factors that can suppress bremsstrahlung and pair production, as well as related effects involving beamstrahlung and QCD processes. After surveying different theoretical approaches, experimental measurements will be covered. Recent accurate measurements by the SLAC E-146 Collaboration will be highlighted, along with several recent theoretical works relating to the experiment. (c) 1999 The American Physical Society

    2003-03-26

    The identification and quantification of explosives and their degradation products in soil and natural waters is helpful in the design of remediation technologies, mobility investigations and performing risk assessments. The objective of this study was to develop a method for the determination of the degradation of nitramine compounds, specifically hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX). The analytical methods developed in this study were based on reversed-phase high performance liquid chromatography (HPLC) using both C-18 and CN bonded silica columns to eliminate common interferences. Contaminant identification was further confirmed by performing spectral analysis of the compounds upon elution. The proposed method yields good separation of RDX from its degradation products and from other common energetic compounds. Method detection limits for the proposed method ranged from 0.01 to 0.03 mg/L. This method satisfies the need for analytical techniques to monitor the formation and subsequent degradation products of toxic and carcinogenic nitrosyl substituted nitramines.

  10. Household Production and Environmental Kuznets Curves. Examining the Desirability and Feasibility of Substitution

    2004-02-01

    This paper provides a theoretical explanation for the widely debated empirical finding of 'Environmental Kuznets Curves', i.e., U-shaped relationships between per-capita income and indicators of environmental quality. We present a household-production model in which the degradation of environmental quality is a by-product of household activities. Households can not directly purchase environmental quality, but can reduce degradation by substituting more expensive cleaner inputs to production for less costly dirty inputs. If environmental quality is a normal good, one expects substitution towards the less polluting inputs, so that increases in income will increase the quality of the environment. It is shown that this only holds for middle income households. Poorer households spend all income on dirty inputs. When they buy more, as income rises, the pollution also rises. they do not want to substitute, as this would reduce consumption of non-environmental services for environmental amenities that are already abundant. Thus, as income rises from low to middle levels, a U shape can result. Yet an N shape might eventually result, as richer households spend all income on clean inputs. Further substitution possibilities are exhausted. Thus as income rises again pollution rises and environmental quality falls.

    Three environmental change scenarios (the best scenario, the most likely scenario and the worst scenario) were used by the APSIM (Agricultural Production System sIMulator) Wheat module to study the possible impacts of future environmental change (climate change plus pCO2 change) on wheat production in the Mid-Lower North of South Australia. GIS software was used to manage spatial-climate data and spatial-soil data and to present the results. Study results show that grain yield (kg ha{sup -1}) was adversely affected under the worst environmental change scenario (-100% {approx} -42%) and the most likely environmental change scenario (-58% {approx} -3%). Grain nitrogen content (% N) either increased or decreased depending on the environmental change scenarios used and climate divisions (-25% {approx} +42%). Spatial variability was found for projected impact outcomes within climate divisions indicating the necessity of including the spatial distribution of soil properties in impact assessment.

    2003-01-01

    An attempt has been made to interpret the outcomes of a Life Cycle Assessment (LCA) in terms of environmental costs. This attempt ensures the environmental accountability of the products while LCA ensures their eco-friendly nature. Keeping this as an objective, a Life Cycle Environmental Cost Analysis (LCECA) model was developed. This new tool incorporates costing into the LCA practice. This model prescribes a life cycle environmental cost model to estimate and correlate the effects of these costs in all the life cycle stages of the product. The newly developed categories of eco-costs are: costs of effluent treatment/control/disposal, environmental management systems, eco-taxes, rehabilitation, energy and savings of recycling and reuse strategies. The mathematical model of LCECA determines quantitative expressions between the total cost of products and the various eco-costs. The eco-costs of the alternatives are compared with the computational LCECA model. This method enables the environmental as well as the economic assessment of products, which leads to cost-effective, eco-friendly design of products

    The island of Sicily has a long standing tradition in citrus growing. We evaluated the sustainability of orange and lemon orchards, under organic and conventional farming, using an energy, environmental and economic analysis of the whole production cycle by using a life cycle assessment approach. These orchard systems differ only in terms of a few of the inputs used and the duration of the various agricultural operations. The quantity of energy consumption in the production cycle was calculated by multiplying the quantity of inputs used by the energy conversion factors drawn from the literature. The production costs were calculated considering all internal costs, including equipment, materials, wages, and costs of working capital. The performance of the two systems (organic and conventional), was compared over a period of fifty years. The results, based on unit surface area (ha) production, prove the stronger sustainability of the organic over the conventional system, both in terms of energy consumption and environmental impact, especially for lemons. The sustainability of organic systems is mainly due to the use of environmentally friendly crop inputs (fertilizers, not use of synthetic products, etc.). In terms of production costs, the conventional management systems were more expensive, and both systems were heavily influenced by wages. In terms of kg of final product, the organic production system showed better environmental and energy performances. Copyright © 2013 Elsevier Ltd. All rights reserved.

    2013-09-01

    Much research has been carried out on governmental support of agri environmental measures (AEM). However, little is known about demands on and incentives from the commercial market for environmental contributions of the farmers. The factors farm structures, level of remuneration and legal framework have been thoroughly investigated. However, demands of the food industry for environmentally friendly goods(1) and their effects on farmers' decisions have not yet been analyzed. Leading companies in the food industry have observed an increasing consumer awareness and, due to higher competition, see an additional need to communicate environmental benefits which result from either organic production methods or agri-environmental measures. To address this research deficit, two case studies were carried out. The first case study is a survey aimed at the industrial food producers' demands with regards to the environmental performance of supplying farms. Concurrently, within a second survey farmers were questioned to find out what conditions are required to implement agri-environmental measures beyond cross compliance and document their environmental performance. This article presents the outcomes of the first case study. The results show that food companies have an interest in the documentation of environmental benefits of supplying farms for their marketing strategies. Provision of support by finance or contract-design is also seen as appropriate tool to promote an environmentally friendly production. In turn the food producers' demand and support for documented environmental services can have a positive influence on farmers' decisions for implementation and documentation of these services. Thus, the surveys provide essential findings for further development of documentation strategies for environmental benefits within the supply chain. Copyright © 2012 Elsevier Ltd.

    We investigate the effectiveness of policies in favor of innovation in renew- able energy under different levels of competition. Using information regarding renewable energy policies, product market regulation and high-quality green patents for OECD countries since the late 1970's, we develop a pre-sample mean count-data econometric specification that also accounts for the endogeneity of policies. We find that renewable energy policies are significantly more effective in fostering green innovation in countries with deregulated energy markets. We also find that public support for renewable energy is crucial only in the generation of high-quality green patents, whereas competition enhances the generation of green patents irrespective of their quality.

    To meet the growing demand, high yielding, but environmentally sustainable agricultural plant production systems are desired. Today, life cycle assessment (LCA) is increasingly used to assess the environmental impact of these agricultural systems. However, the impact results are very diverse due to management decisions or local natural conditions. The impact of grain maize is often generalized and an average is taken. Therefore, we studied variation in production systems. Four types of drivers for variability are distinguished: policy, farm management, year-to-year weather variation and innovation. For each driver, scenarios are elaborated using ReCiPe and CEENE (Cumulative Exergy Extraction from the Natural Environment) to assess the environmental footprint. Policy limits fertilisation levels in a soil-specific way. The resource consumption is lower for non-sandy soils than for sandy soils, but entails however more eutrophication. Farm management seems to have less influence on the environmental impact when considering the CEENE only. But farm management choices such as fertiliser type have a large effect on emission-related problems (e.g. eutrophication and acidification). In contrast, year-to-year weather variation results in large differences in the environmental footprint. The difference in impact results between favourable and poor environmental conditions amounts to 19% and 17% in terms of resources and emissions respectively, and irrigation clearly is an unfavourable environmental process. The best environmental performance is obtained by innovation as plant breeding results in a steadily increasing yield over 25 years. Finally, a comparison is made between grain maize production in Flanders and a generically applied dataset, based on Swiss practices. These very different results endorse the importance of using local data to conduct LCA of plant production systems. The results of this study show decision makers and farmers how they can improve the

    Full Text Available The purpose of these studies is to justify the feasibility of recycling different types of industrial waste instead of conventional expensive raw materials in production of environmentally friendly aerated concrete with required construction and operational properties. The impact of wastes from various industries on the environmental condition of affected areas, as well as the results of their environmental assessment were analyzed to determine whether these wastes could be used in production of high-performance building materials. The assessment of industrial wastes in aerated concrete production suggests that industrial wastes of hazard class IV can be recycled to produce aerated concrete. An environmentally friendly method for large-scale waste recycling, including a two-step environmentally sustainable mechanism, was developed. The basic quality indicators of the modified aerated concrete proved that the environmental safety could be enhanced by strengthening the structure, increasing its uniformity and improving thermal insulation properties. The modified non-autoclaved aerated concrete products with improved physical and operational properties were developed. They have the following properties: density – D700; class of concrete – B3.5; thermal transmittance coefficient – 0.143 W/(m·°C; frost resistance – F75.

    In the aftermath of the Cold War, the US has begun addressing the environmental consequences of five decades of nuclear weapons production. In support of this effort, the National Defense Authorization Act for Fiscal Year 1995 directed the Department of Energy (DOE) to describe the waste streams generated during each step in the production of nuclear weapons. Accordingly, this report responds to this mandate, and it is the Department`s first comprehensive analysis of the sources of waste and contamination generated by the production of nuclear weapons. The report also contains information on the missions and functions of nuclear weapons facilities, on the inventories of waste and materials remaining at these facilities, as well as on the extent and characteristics of contamination in and around these facilities. This analysis unites specific environmental impacts of nuclear weapons production with particular production processes. The Department used historical records to connect nuclear weapons production processes with emerging data on waste and contamination. In this way, two of the Department`s legacies--nuclear weapons manufacturing and environmental management--have become systematically linked. The goal of this report is to provide Congress, DOE program managers, non-governmental analysts, and the public with an explicit picture of the environmental results of each step in the nuclear weapons production and disposition cycle.

    Beef makes a substantial contribution to food security, providing protein, energy and also essential micro-nutrients to human populations. Rumination allows cattle - and other ruminant species - to digest fibrous feeds that cannot be directly consumed by humans and thus to make a net positive contribution to food balances. This contribution is of particular importance in marginal areas, where agro-ecological conditions and weak infrastructures do not offer much alternative. It is also valuable where cattle convert crop residues and by-products into edible products and where they contribute to soil fertility through their impact on nutrients and organic matter cycles. At the same time, environmental sustainability issues are acute. They chiefly relate to the low efficiency of beef cattle in converting natural resources into edible products. Water use, land use, biomass appropriation and greenhouse gas emissions are for example typically higher per unit of edible product in beef systems than in any other livestock systems, even when corrected for nutritional quality. This particularly causes environmental pressure when production systems are specialized towards the delivery of edible products, in large volumes. The paper discusses environmental challenges at global level, recognizing the large diversity of systems. Beef production is faced with a range of additional sustainability challenges, such as changing consumer perceptions, resilience to climate change, animal health and inequities in access to land and water resources. Entry-points for environmental sustainability improvement are discussed within this broader development context. Copyright © 2015. Published by Elsevier Ltd.

    Despite the potential of declared serving size to encourage appropriate portion size consumption, most countries including Australia have not developed clear reference guidelines for serving size. The present study evaluated variability in manufacturer-declared serving size of discretionary food and beverage products in Australia, and how declared serving size compared with the 2013 Australian Dietary Guideline (ADG) standard serve (600 kJ). Serving sizes were obtained from the Nutrition Information Panel for 4466 packaged, discretionary products in 2013 at four large supermarkets in Sydney, Australia, and categorised into fifteen categories in line with the 2013 ADG. For unique products that were sold in multiple package sizes, the percentage difference between the minimum and the maximum serving size across different package sizes was calculated. A high variation in serving size was found within the majority of food and beverage categories - for example, among 347 non-alcoholic beverages (e.g. soft drinks), the median for serving size was 250 (interquartile range (IQR) 250, 355) ml (range 100-750 ml). Declared serving size for unique products that are available in multiple package sizes also showed high variation, particularly for chocolate-based confectionery, with median percentage difference between minimum and maximum serving size of 183 (IQR 150) %. Categories with a high proportion of products that exceeded the 600 kJ ADG standard serve included cakes and muffins, pastries and desserts (≥74 % for each). High variability in declared serving size may confound interpretation and understanding of consumers interested in standardising and controlling their portion selection. Future research is needed to assess if and how standardising declared serving size might affect consumer behaviour.

    The issues of showing relations between environmental and economic indicators (further - environmental and economic interactions) of coke and by-product process are considered in the article. The purpose of the study is to reveal the regularities of the functioning of the local environmental and economic system on the basis of revealed spectrum of environmental and economic interactions. A simplified scheme of the environmental and economic system "coke and by-product process - the environment" was developed. The forms of the investigated environmental-economic interactions were visualized and the selective interpretation of the tightness of the established connection was made. The main result of the work is modeling system of environmental and economic interactions that allows increasing the efficiency of local ecological and economic system management and optimizing the "interests" of an industrial enterprise - the source of negative impact on the environment. The results of the survey can be recommended to government authorities and industrial enterprises with a wide range of negative impact forms to support the adoption of effective management decisions aimed at sustainable environmental and economic development of the region or individual municipalities.

    The production of electricity creates environmental insults whose costs are not fully reflected in the prices paid by consumers for electricity services. Failure to incorporate these external costs leads to economically inefficient production and consumption decisions. The present work reviews two related efforts to address this market distortion. The first concerns progress in estimating the uninternalized environmental costs of electricity production. The second concerns market-based approaches to internalizing these costs in electricity production and consumption decisions. 10 tabs.; 41 refs

    In Senegal, two stocks of white shrimp ( Penaeusnotialis) are intensively exploited, one in the north and another in the south. We used surplus production models including environmental effects to analyse their changes in abundance over the past 10 years and to estimate their Maximum Sustainable Yield (MSY) and the related fishing effort ( EMSY). First, yearly abundance indices were estimated from commercial statistics using GLM techniques. Then, two environmental indices were alternatively tested in the model: the coastal upwelling intensity from wind speeds provided by the SeaWifs database and the primary production derived from satellite infrared images of chlorophyll a. Models were fitted, with or without the environmental effect, to the 1996-2005 time series. They express stock abundance and catches as functions of the fishing effort and the environmental index (when considered). For the northern stock, fishing effort and abundance fluctuate over the period without any clear trends. The model based on the upwelling index explains 64.9% of the year-to-year variability. It shows that the stock was slightly overexploited in 2002-2003 and is now close to full exploitation. Stock abundance strongly depends on environmental conditions; consequently, the MSY estimate varies from 300 to 900 tons according to the upwelling intensity. For the southern stock, fishing effort has strongly increased over the past 10 years, while abundance has been reduced 4-fold. The environment has a significant effect on abundance but only explains a small part of the year-to-year variability. The best fit is obtained using the primary production index ( R2 = 0.75), and the stock is now significantly overfished regardless of environmental conditions. MSY varies from 1200 to 1800 tons according to environmental conditions. Finally, in northern Senegal, the upwelling is highly variable from year to year and constitutes the major factor determining productivity. In the south, hydrodynamic

    Controlling fugitive dust while protecting natural resources is a challenge faced by all managers of unpaved roads. Unfortunately, road managers choosing between dust control products often have little objective environmental information to aid their decisions. To address this information gap, the U.S. Geological Survey and the U.S. Fish and Wildlife Service collaborated on a field test of three dust control products with the objectives of (a) evaluating product performance under real-world conditions, (b) verifying the environmental safety of products identified as practically nontoxic in laboratory tests, and (c) testing the feasibility of several environmental monitoring techniques for use in dust control tests. In cooperation with refuge staff and product vendors, three products (one magnesium chloride plus binder, one cellulose, and one synthetic fluid plus binder) were applied in July 2012 to replicated road sections at the Hagerman National Wildlife Refuge in Texas. These sections were monitored periodically for 12 months after application. Product performance was assessed by mobile-mounted particulate-matter meters measuring production of fugitive dust and by observations of road conditions. Environmental safety was evaluated through on-site biological observations and leaching tests with samples of treated aggregate. All products reduced dust and improved surface condition during those 12 months. Planned environmental measurements were not always compatible with day-to-day refuge management actions; this incompatibility highlighted the need for flexible biological monitoring plans. As one of the first field tests of dust suppressants that explicitly incorporated biological endpoints, this effort provides valuable information for improving field tests and for developing laboratory or semifield alternatives.

    Animations generated by interactive 3D computer graphics applications are typically portrayed either from a particular character`s point of view or from a small set of strategically-placed viewpoints. By ignoring camera placement, such applications fail to realize important storytelling capabilities that have been explored by cinematographers for many years. In this paper, we describe several of the principles of cinematography and show how they can be formalized into a declarative language, called the Declarative Camera Control Language (DCCL). We describe the application of DCCL within the context of a simple interactive video game and argue that DCCL represents cinematic knowledge at the same level of abstraction as expert directors by encoding 16 idioms from a film textbook. These idioms produce compelling animations, as demonstrated on the accompanying videotape.

    The liberalisation of energy markets has increased the need to enlarge the information base of fuel chains, to evaluate the environmental quality of energy products transparently and to communicate results in a credible way. The preparedness of energy purchasers, producers and sellers to support energy choices of their customers and to meet the information requirements of various stake holders can be strengthened. The environmental impacts related to energy products are turning into a significant dimension of competitiveness. Possibilities to promote market-driven environmental protection mechanisms and to construct incentives, which cover the whole energy production system exist and can be supported. Knowledge of environmental impacts of various energy products can be increased by means of several supplementary instruments like eco-profiles, environmental labels and life cycle assessments of products. Life cycle assessment forms a systematic basis of information, which supports the environmental communications directed to various stake holders. In this study selected public LCA-studies concerning energy production have been compared, criteria of green energy have been charted and their outlook has been assessed. In addition the development of an LCA- based relative environmental performance indicator system, which supports various transparent comparisons, has been outlined. The mapping of methodological differences of published LCA-studies regarding various energy alternatives proves, that there is differences e.g. in allocation principles, system boundaries, and age of source information and in many other details. These discrepancies should be known, because they also affect the results. That is why the use of available LCA studies as a basis for comparative assertions may be problematic. The renewability of an energy source is a threshold requirement in eco-energy criteria formulated and introduced by Finnish, Swedish and Norwegian nature conservation

    The environmental impacts of strawberries have been assessed in several studies. However, these studies either present dissimilar results or only focus on single impact categories without offering a comprehensive overview of environmental impacts. We applied the product environmental footprint (PEF) methodology to broadly indicate the environmental impacts of various strawberry production systems in Germany and Estonia by 15 impact categories. Data for the 7 case studies were gathered from two farms with organic and two farms with conventional open field production systems in Estonia and from one farm with conventional open field and one farm with a polytunnel and greenhouse production system in Germany. The greenhouse production system had the highest environmental impact with a PEF of 0.0040. In the field organic production systems, the PEF was 0.0029 and 0.0028. The field conventional production systems resulted in a PEF of 0.0008, 0.0009 and 0.0002. Polytunnel PEF was 0.0006. Human toxicity cancer effects, particulate matter and human toxicity non-cancer effects resulted in the highest impact across all analysed production systems. The main contributors were electricity for cooling, heating the greenhouse and the use of agricultural machinery including fuel burning. While production stage contributed 85% of the total impact in the greenhouse, also other life cycle stages were important contributors: pre-chain resulted in 71% and 90% of impact in conventional and polytunnels, respectively, and cooling was 47% in one organic system. Environmental impact from strawberry cooling can be reduced by more efficient use of the cooling room, increasing the strawberry yield or switching from oil shale electricity to other energy sources. Greenhouse heating is the overall impact hotspot even if it based on renewable resources. A ranking of production systems based on the environmental impact is possible only if all relevant impacts are included. Future studies should aim

  6. 'Underutilised' agricultural land: its definitions, potential use for future biomass production and its environmental implications

    2017-04-01

    A growing bioeconomy and increased demand for biomass products on food, health, fibre, industrial products and energy require land resources for feedstock production. It has resulted in significant environmental and socio-economic challenges on a global scale. As a result, consideration of such effects of land use change (LUC) from biomass production (particularly for biofuel feedstock) has emerged as an important area of policy and research, and several potential solutions have been proposed to minimise such adverse LUC effects. One of these solutions is the use of lands that are not in production or not suitable for food crop production, such as 'marginal', 'degraded', 'abandoned' and 'surplus' agricultural lands for future biomass production. The terms referring to these lands are usually associated with the potential production of 'marginal crops', which can grow in marginal conditions (e.g. poor soil fertility, low rainfall, drought) without much water and agrochemical inputs. In our research, we referred to these lands as 'underutilised' agricultural land and attempted to define them for our case study areas located in Australia and Central and Eastern Europe (CEE). Our goal is to identify lands that can be used for future biomass production and to evaluate their environmental implications, particularly impacts related to biodiversity, water and soil at a landscape scale. The identification of these lands incorporates remote sensing and spatially explicit approaches. Our findings confirmed that there was no universal or single definition of the term 'underutilised' agricultural land as the definitions significantly vary by country and region depending not only on the biophysical environment but also political, institutional and socio-economic conditions. Moreover, our results highlighted that the environmental implications of production of biomass on 'underutilised' agricultural land for biomass production are highly controversial. Thus land use change

    Kordjamshidi, Parisa; Roth, Dan; Wu, Hao

    2015-07-01

    We present Saul , a new probabilistic programming language designed to address some of the shortcomings of programming languages that aim at advancing and simplifying the development of AI systems. Such languages need to interact with messy, naturally occurring data, to allow a programmer to specify what needs to be done at an appropriate level of abstraction rather than at the data level, to be developed on a solid theory that supports moving to and reasoning at this level of abstraction and, finally, to support flexible integration of these learning and inference models within an application program. Saul is an object-functional programming language written in Scala that facilitates these by (1) allowing a programmer to learn, name and manipulate named abstractions over relational data; (2) supporting seamless incorporation of trainable (probabilistic or discriminative) components into the program, and (3) providing a level of inference over trainable models to support composition and make decisions that respect domain and application constraints. Saul is developed over a declaratively defined relational data model, can use piecewise learned factor graphs with declaratively specified learning and inference objectives, and it supports inference over probabilistic models augmented with declarative knowledge-based constraints. We describe the key constructs of Saul and exemplify its use in developing applications that require relational feature engineering and structured output prediction.

    Microalgae have been currently recognized as a group of the most potential feedstocks for biodiesel production due to high productivity potential, efficient biosynthesis of lipids, and less competition with food production. Moreover, utilization of microalgae with environmental purposes (CO{sub 2} fixation, NO{sub x}, and wastewater treatment) and biorefinery has been reported. However, there are still challenges that need to be addressed to ensure stable large-scale production with positive net energy balance. This review gives an overview of the current status of the application of microalgae in biodiesel production and environmental protection. The practical problems not only facing the microalgae biodiesel production but also associated with microalgae application for environmental pollution control, in particular biological fixation of greenhouse gas (CO{sub 2} and NO{sub x}) and wastewater treatment are described in detail. Notably, the synergistic combination of various applications (e.g., food, medicine, wastewater treatment, and flue gas treatment) with biodiesel production could enhance the sustainability and economics of the algal biodiesel production system.

This review gives an overview of the current status of the application of microalgae in biodiesel production and environmental protection. The practical problems not only facing the microalgae biodiesel production but also associated with microalgae application for environmental pollution control, in particular biological fixation of greenhouse gas (CO2 and NOX and wastewater treatment are described in detail. Notably, the synergistic combination of various applications (e.g. food, medicine, wastewater treatment and flue gas treatment with biodiesel production could enhance the sustainability and economics of the algal biodiesel production system.

    The health and environmental effects of chemical processes can be assessed during the initial stage of their production. In this paper, the Chemical Screening Tool for Exposure and Environmental Release (ChemSTEER) software was used to compare the health and environmental risks of spray pyrolysis and wet chemical techniques for the fabrication of nanostructured metal oxide on a semi-industrial scale with a capacity of 300 kg/day in Iran. The pollution sources identified in each production process were pairwise compared in Expert Choice software using indicators including respiratory damage, skin damage, and environmental damages including air, water, and soil pollution. The synthesis of nanostructured zinc oxide using the wet chemical technique (with 0.523 wt%) leads to lower health and environmental risks compared to when spray pyrolysis is used (with 0.477 wt%). The health and environmental risk assessment of nanomaterial production processes can help select safer processes, modify the operation conditions, and select or modify raw materials that can help eliminate the risks.

    The environmental impacts of various hydrogen production processes are evaluated and compared, considering several energy sources and using life cycle analysis. The results indicate that hydrogen produced by thermochemical water decomposition cycles are more environmentally benign options compared to conventional steam reforming of natural gas. The nuclear based four-step Cu–Cl cycle has the lowest global warming potential (0.559 kg CO{sub 2}-eq per kg hydrogen production), mainly because it requires the lowest quantity of energy of the considered processes. The acidification potential results show that biomass gasification has the highest impact on environment, while wind based electrolysis has the lowest. The relation is also investigated between efficiency and environmental impacts. -- Highlights: • Environmental performance of nuclear-based hydrogen production is investigated. • The GWP and AP results are compared with various hydrogen production processes. • Nuclear based 4-step Cu–Cl cycle is found to be an environmentally benign process. • Wind-based electrolysis has the lowest AP value.

    Full Text Available Industrial hydrogen production via alkaline water electrolysis (AEL is a mature hydrogen production method. One argument in favor of AEL when supplied with renewable energy is its environmental superiority against conventional fossil-based hydrogen production. However, today electricity from the national grid is widely utilized for industrial applications of AEL. Also, the ban on asbestos membranes led to a change in performance patterns, making a detailed assessment necessary. This study presents a comparative Life Cycle Assessment (LCA using the GaBi software (version 6.115, thinkstep, Leinfelden-Echterdingen, Germany, revealing inventory data and environmental impacts for industrial hydrogen production by latest AELs (6 MW, Zirfon membranes in three different countries (Austria, Germany and Spain with corresponding grid mixes. The results confirm the dependence of most environmental effects from the operation phase and specifically the site-dependent electricity mix. Construction of system components and the replacement of cell stacks make a minor contribution. At present, considering the three countries, AEL can be operated in the most environmentally friendly fashion in Austria. Concerning the construction of AEL plants the materials nickel and polytetrafluoroethylene in particular, used for cell manufacturing, revealed significant contributions to the environmental burden.

    Although there are numerous studies suggesting hydrothermal carbonization is an environmentally advantageous process for transformation of wastes to value-added products, a systems level evaluation of the environmental impacts associated with hydrothermal carbonization and subsequent hydrochar combustion has not been conducted. The specific objectives of this work are to use a life cycle assessment approach to evaluate the environmental impacts associated with the HTC of food wastes and the subsequent combustion of the generated solid product (hydrochar) for energy production, and to understand how parameters and/or components associated with food waste carbonization and subsequent hydrochar combustion influence system environmental impact. Results from this analysis indicate that HTC process water emissions and hydrochar combustion most significantly influence system environmental impact, with a net negative GWP impact resulting for all evaluated substituted energy-sources except biomass. These results illustrate the importance of electricity production from hydrochar particularly when it is used to offset coal-based energy sources. HTC process water emissions result in a net impact to the environment, indicating a need for developing appropriate management strategies. Results from this analysis also highlight a need for additional exploration of liquid and gas-phase composition, a better understanding of how changes in carbonization conditions (e.g., reaction time and temperature) influence metal and nutrient fate, and the exploration of liquid-phase treatment.

    This study addressed the issue of using biological systems for hydrogen production as an environmentally sound alternative to conventional thermochemical and electrochemical processes. In particular, it examined the potential for anaerobic fermentation for biological hydrogen production and the possibility of coupling gaseous energy generation with simultaneous treatment of biodegradable waste materials. The study focused on hydrogen production by anaerobic fermentation using Enterobacter cloacae DM11, a Gram-negative, motile facultative anaerobe. Although hydrogen production by these bacteria depends on many environmental parameters, there is very little information on the effects of these factors in the hydrogen production potential of this organism. For that reason, this study examined the effect of initial medium pH, reaction temperature, initial glucose concentration, and iron (Fe2+) concentration on the fermentative production of hydrogen. Fermentative hydrogen production was carried out by Enterobacter cloacae DM11, using glucose as the substrate. Batch cultivations were performed in a 500 ml custom-designed vertical tubular bioreactor. The maximum molar yield of hydrogen was 3.31 mol (mol glucose){sub 1}. The rate and cumulative volume of hydrogen production decreased at higher initial glucose concentration. The pH of 6.5 at a temperature of 37 degrees C was most suitable for maximum rate of production of hydrogen in batch fermentation. The addition of Fe2+ on hydrogen production had a marginal enhancing effect on total hydrogen production. A simple model developed from the modified Gompertz equation was used to fit the cumulative hydrogen production curve and to estimate the hydrogen production potential, maximum production rate, and lag time. It was concluded that these study results could be used in the development of a high rate continuous hydrogen production process. 30 refs., 4 tabs., 3 figs.

  4. Catalyst-Free Biodiesel Production Methods: A Comparative Technical and Environmental Evaluation

    Directory of Open Access Journals (Sweden)

    Oseweuba Valentine Okoro

    2018-01-01

    Full Text Available In response to existing global focus on improved biodiesel production methods via highly efficient catalyst-free high temperature and high pressure technologies, this study considered the comparative study of catalyst-free technologies for biodiesel production as an important research area. In this study, therefore, catalyst-free integrated subcritical lipid hydrolysis and supercritical esterification and catalyst-free one step supercritical transesterification processes for biodiesel production have been evaluated via undertaking straight forward comparative energetic and environmental assessments. Energetic comparisons were undertaken after heat integration was performed since energy reduction has favourable effects on the environmental performance of chemical processes. The study confirmed that both processes are capable of producing biodiesel of high purity with catalyst-free integrated subcritical lipid hydrolysis and supercritical esterification characterised by a greater energy cost than catalyst-free one step supercritical transesterification processes for an equivalent biodiesel productivity potential. It was demonstrated that a one-step supercritical transesterification for biodiesel production presents an energetically more favourable catalyst-free biodiesel production pathway compared to the integrated subcritical lipid hydrolysis and supercritical esterification biodiesel production process. The one-step supercritical transesterification for biodiesel production was also shown to present an improved environmental performance compared to the integrated subcritical lipid hydrolysis and supercritical esterification biodiesel production process. This is because of the higher potential environment impact calculated for the integrated subcritical lipid hydrolysis and supercritical esterification compared to the potential environment impact calculated for the supercritical transesterification process, when all material and energy flows are

  5. Implications of environmental regulations on refinery product specification, operation and investment

    Amin, M.M.

    1992-01-01

    During the 1980s, refiners mainly in OECD countries were occupied with improving their refinery configurations for producing high-value light products which would not only satisfy the product demand slate but also meet the increasingly restrictive environmental regulations. In the 1990s refiners will continue to be challenged to improve the world's air quality not only by producing products that minimize emissions of toxic and hazardous hydrocarbons, but also through the refinery operation itself by investment in upgrading the industry and products to cope with the constant flow of new regulations. These investments will not only be limited to consuming centres but will also be extended to cover exporting refineries as well due to competition of acquiring market shares for product exports. The additional cost will be directly related to product quality and site regulations and will vary from one country to the other. This paper deals mainly with the air pollution and the impact of related environmental issues on the refining industry. Environmental regulations for refinery products in the USA and Europe are examined and international regulations for the tanker industry are noted. (author)

    2013-01-01

    We analyse optimal environmental policies in a market that is vertically differentiated in terms of the energy efficiency of products. Considering energy taxes, subsidies to firms for investment in more eco-friendly products, and product standards, we are particularly interested in how distributional goals in addition to environmental goals shape the choice of policy instruments. We find that an industry-friendly government levies an energy tax to supplement a lax product standard, but shies away from subsidies to firms. By contrast, a consumer-friendly government relies heavily on a strict product standard and additionally implements a moderate subsidy to firms, but avoids energy taxes. - Highlights: ► We analyse how distributional goals shape environmental policy. ► Firms invest in the energy efficiency of their products and compete in prices. ► An industry-friendly government implements an energy tax and a lax product standard. ► A consumer-friendly government chooses a subsidy to firms instead of an energy tax. ► A consumer-friendly government implements a strict energy efficiency standard

    Minimizing production cost in a manufacturing company will increase the profit of the company. The cutting parameters will affect total processing time which then will affect the production cost of machining process. Besides affecting the production cost and processing time, the cutting parameters will also affect the environment. An optimization model is needed to determine the optimum cutting parameters. In this paper, we develop an optimization model to minimize the production cost and the environmental impact in CNC turning process. The model is used a multi objective optimization. Cutting speed and feed rate are served as the decision variables. Constraints considered are cutting speed, feed rate, cutting force, output power, and surface roughness. The environmental impact is converted from the environmental burden by using eco-indicator 99. Numerical example is given to show the implementation of the model and solved using OptQuest of Oracle Crystal Ball software. The results of optimization indicate that the model can be used to optimize the cutting parameters to minimize the production cost and the environmental impact.

    Lemaire, Gilles; Gastal, François; Franzluebbers, Alan; Chabbi, Abad

    2015-11-01

    A need to increase agricultural production across the world to ensure continued food security appears to be at odds with the urgency to reduce the negative environmental impacts of intensive agriculture. Around the world, intensification has been associated with massive simplification and uniformity at all levels of organization, i.e., field, farm, landscape, and region. Therefore, we postulate that negative environmental impacts of modern agriculture are due more to production simplification than to inherent characteristics of agricultural productivity. Thus by enhancing diversity within agricultural systems, it should be possible to reconcile high quantity and quality of food production with environmental quality. Intensification of livestock and cropping systems separately within different specialized regions inevitably leads to unacceptable environmental impacts because of the overly uniform land use system in intensive cereal areas and excessive N-P loads in intensive animal areas. The capacity of grassland ecosystems to couple C and N cycles through microbial-soil-plant interactions as a way for mitigating the environmental impacts of intensive arable cropping system was analyzed in different management options: grazing, cutting, and ley duration, in order to minimize trade-offs between production and the environment. We suggest that integrated crop-livestock systems are an appropriate strategy to enhance diversity. Sod-based rotations can temporally and spatially capture the benefits of leys for minimizing environmental impacts, while still maintaining periods and areas of intensive cropping. Long-term experimental results illustrate the potential of such systems to sequester C in soil and to reduce and control N emissions to the atmosphere and hydrosphere.

    2017-02-08

    Animal production in China has achieved considerable progress and contributes to 46% of the total agriculture output value of the country. However, this fast expansion of animal production has led to environmental pollution. In this article, we review the status of soil, water, and air pollution associated with animal production in China and analyze the main sources of the pollutants. The government has promulgated regulations and standards, and effective models and technologies have been developed to control pollution during the last 10 years. Because nutrition and feed strategies represent the most effective method of controlling environmental pollution at the source, this review focuses on nutritional technologies, including accurate feed formulation, rational use of additives, and proper processing of feeds. The advances of modern biotechnology and big data systems also provide more modern approaches to decreasing wastage release. These nutritional strategies are expected to promote sustainable development of animal production.

    2013-03-01

    This report covers the third part of a larger U.S. Department of Energy (DOE) project to assess the life-cycle environmental and resource impacts in the manufacturing, transport, use, and disposal of light-emitting diode (LED) lighting products in relation to incumbent lighting technologies. All three reports are available on the DOE website (www.ssl.energy.gov/tech_reports.html). • Part 1: Review of the Life-Cycle Energy Consumption of Incandescent, Compact Fluorescent and LED Lamps; • Part 2: LED Manufacturing and Performance; • Part 3: LED Environmental Testing. Parts 1 and 2 were published in February and June 2012, respectively. The Part 1 report included a summary of the life-cycle assessment (LCA) process and methodology, provided a literature review of more than 25 existing LCA studies of various lamp types, and performed a meta-analysis comparing LED lamps with incandescent and compact fluorescent lamps (CFLs). Drawing from the Part 1 findings, Part 2 performed a more detailed assessment of the LED manufacturing process and used these findings to provide a comparative LCA taking into consideration a wider range of environmental impacts. Both reports concluded that the life-cycle environmental impact of a given lamp is dominated by the energy used during lamp operation—the upstream generation of electricity drives the total environmental footprint of the product. However, a more detailed understanding of end-of-life disposal considerations for LED products has become increasingly important as their installation base has grown. The Part 3 study (reported herein) was undertaken to augment the LCA findings with chemical analysis of a variety of LED, CFL, and incandescent lamps using standard testing procedures. A total of 22 samples, representing 11 different models, were tested to determine whether any of 17 elements were present at levels exceeding California or Federal regulatory thresholds for hazardous waste. Key findings include: • The selected

    Full Text Available Accelerating demand to reduce the environmental impact of fossil fuels has been driving widespread attention to renewable fuels, such as biogas. In fact, in the last decade numerous policy guidelines and laws regarding energy, the environment and agriculture have been issued to encourage the use of animal sewage as a raw material for the production of biogas. The production of energy from biogas in a dairy farm can provide a good opportunity for sustainable rural development, augmenting the farm’s income from traditional sources and helping to reduce the overall environmental impact of the energy sector. This paper investigates the trade-off between the environmental and economic benefits of an agro-energy farm in the Umbria region of Italy that employs livestock sewage and manure, dedicated energy crops (corn and triticale silage and olive waste. The environmental analysis was performed using the LCA methodology, while the economic investigation was carried out by reconstructing the economic balance of the agro-energetic supply chain based on the budgets of each activity performed. The LCA results show, on the one hand, the predominant weight of producing dedicated crops compared to all other processes in the supply chain and, on the other hand, a significant reduction in environmental impact compared to that caused by energy production from fossil fuels. Economic analysis revealed that the results depend significantly on what rate per kWh the government incentives guarantee to agricultural producers of renewable energy.

    Over the last years, increasing attention has been paid to environmental concerns related to food production and potential solutions to this issue. Among the different strategies being considered to reduce the impact food production has on the environment, only moderate has been paid to the extension of shelf life; a longer shelf life can reduce food losses as well as the economic and environmental impacts of the distribution logistics. The aim of this study is to assess the environmental performance of whole-wheat breadsticks with extended shelf lives and to evaluate whether the shelf-life extension is an effective mitigation solution from an environmental point of view. To this purpose, the life cycle assessment (LCA) approach was applied from a "cradle-to-grave" perspective. Rosmarinic acid was used as an antioxidant to extend the shelf life. To test the robustness of the results and to investigate the influence of the choices made in the modelling phase, a sensitivity and uncertainty analysis were carried out. The achieved results highlighted how, for 10 of the 12 evaluated impact categories, the shelf-life extension is a proper mitigation solution, and its effectiveness depends on the magnitude of product loss reduction that is achieved. The shelf-life extension doesn't allow for the reduction of environmental impact in the categories of human toxicity, cancer effects and freshwater eutrophication. Copyright © 2018 Elsevier B.V.

  4. Making sense of site declarations: Canadian declarations under article 2.a. (iii) of the Additional Protocol

    Full text: While this paper will provide an overview of Additional Protocol implementation activities in Canada, this paper will also deal with a specific, albeit important, component of Canada's initial declaration under the Additional Protocol: site definitions and declarations. A clear description of the problems, solutions and compromises in making site declarations across a variety of sites in Canada would provide a useful insight into the process as other States prepare to do the same. Through the Model Protocol Additional to Safeguards Agreements Between Member States and the International Atomic Energy Agency, provisions exist to fulfil a longstanding gap in the coverage of international safeguards. The success of these new provisions are dependent on the extent to which declarations balance the intent of expanded declarations and the practical difficulties in making such declarations. The prerogative to delineate site boundaries lies with the Member State. In doing so, four factors merit careful consideration. First, Article 18.b of the Additional Protocol draws connections between facility definition and site delineation. Under comprehensive safeguards, information on facilities has already been submitted to the IAEA specifying site layouts in the design information questionnaire. Consistency between the site layouts specifications of the design information and site definition under the Additional Protocol is important, as differences will lead to inconsistencies, which will have to be resolved during implementation. Second, while Article 18.b specified that specific essential services, co-located in close geographic proximity, should be considered as part of the same site, there are instances where site definition is complicated by close proximity of other, but separate, safeguarded facilities and the existence of services related, but not essentials according to the definitions of the Additional Protocol, to the site. Third, practical limitations come

  5. Perception of the environmental impacts of current and alternative modes of pig production by stakeholder groups.

    Petit, Jean; van der Werf, Hayo M G

    2003-08-01

    The current industrial pig production model is in crisis, due to its association with environmental pollution, doubtful product quality and lack of animal well-being. In Bretagne (France), a region of intensive pig production, a survey of seven stakeholder groups concerned with pig production was conducted, as part of a research programme dedicated to the assessment of the environmental impact of different modes of pig production. A very large majority of pig producers (93%) and their suppliers (100%) considers pig farms as an asset for the region, whereas a majority of scientists (58%), activists (78%) and consumers (54%) sees it as a handicap. Differences among stakeholder groups are minor with respect to the perceived importance of environmental and social issues. Stakeholders agree on the relative level of responsibility of pig farms with respect to specific problems. For all groups unpleasant odours and water quality come first with respect to responsibility, for most groups soil quality comes second, followed by product safety and air quality. For a future improved mode of pig production, 76% of pig producers and their suppliers prefer to adapt the current model, for all other groups the majority prefers an alternative model. While pig producers and their suppliers prefer a slurry-based housing system, all other groups prefer a straw-based system. Pig producers see the slurry-based system as technically superior and associate the straw-based system with poor working conditions, whereas consumers associate the slurry-based system in the first place with poor water quality and associate the straw-based system with less pollution. These results will be of use in the research programme on the environmental impact of modes of pig production, as they indicate the environmental impacts to be considered and their relative importance. The results will also help in deciding which options should be assessed. It is concluded that the poor image of the current pig

It is proven that the photovoltaic conversion or the use of heat of Sun radiation, the water energy, the utilization of the wind, the biomass production, the use of geothermal energy can all produce big amounts of energy for human use. In addition, the nuclear energy from fission is a technology, which has already long history and is widely used. However, these all, like the fossil energy sources, have great impacts on the environment. Nevertheless, the comparison of the environmental effects of these alternative energy sources is not easy. The effects are of considerable different natures and their spatial and the time distributions vary on large scales. The present work overviews the principles and the methodological prerequisites of performing a comparative analysis of the environmental effects for the non-fossil energy production methods. After establishing the basic principles for comparison, we shall go through all the non-fossil energy sources and analyze the most important environmental impacts of each energy production method. In conclusion, the comparison of the environmental effects will be discussed.

    Numerous indicators are currently available for environmental impact assessments, especially in the field of Life Cycle Impact Assessment (LCIA). Because decision-making on the basis of hundreds of indicators simultaneously is unfeasible, a nonredundant key set of indicators representative of the overall environmental impact is needed. We aimed to find such a nonredundant set of indicators based on their mutual correlations. We have used Principal Component Analysis (PCA) in combination with an optimization algorithm to find an optimal set of indicators out of 135 impact indicators calculated for 976 products from the ecoinvent database. The first four principal components covered 92% of the variance in product rankings, showing the potential for indicator reduction. The same amount of variance (92%) could be covered by a minimal set of six indicators, related to climate change, ozone depletion, the combined effects of acidification and eutrophication, terrestrial ecotoxicity, marine ecotoxicity, and land use. In comparison, four commonly used resource footprints (energy, water, land, materials) together accounted for 84% of the variance in product rankings. We conclude that the plethora of environmental indicators can be reduced to a small key set, representing the major part of the variation in environmental impacts between product life cycles.

  1. Alternative Silver Production by Environmental Sound Processing of a Sulfo Salt Silver Mineral Found in Bolivia

    2018-02-01

    Full Text Available Very often, the production of silver causes devastating environmental issues, because of the use of toxic reagents like cyanide and mercury. Due to severe environmental damage caused by humans in the last decades, the social awareness regarding the sustainable production processes is on the rise. Terms like “sustainable” and “green” in product descriptions are becoming more and more popular and producers are forced to satisfy the rising environmental awareness of their customers. Within this work, an alternative environmental sound silver recovery process was developed for a vein type silver ore from Mina Porka, Bolivia. A foregoing characterization of the input material reveals its mineral composition. In the following mineral processing, around 92.9% silver was concentrated by separating 59.5 wt. % of non-silver minerals. Nitric acid leaching of the generated concentrate enabled a silver recovery of up to 98%. The dissolved silver was then separated via copper cementation to generate a metallic silver product of >99% purity. Summarizing all process steps, a silver yield of 87% was achieved in lab scale. A final upscaling trial was conducted to prove the process’ robustness. Within this trial, almost 4 kg of metallic silver with a purity of higher than 99.5 wt. % was produced.

    Although the term sustainable development is commonly used today, there is not yet a commonly accepted definition. Various ways of measuring sustainability have been proposed. To show how these issues are being effectively addressed in modern uranium developments, we will review some methods of defining the environmental component of sustainable development in the mining and mineral-processing sector. Environmental impacts associated with uranium extraction and processing in modern facilities are modest. Air and water emissions are well controlled. Waste materials are subject to comprehensive management programmes. The size of the impacted area is smaller than in other energy sectors, providing good opportunity to minimize land impact. Experience over the past three decades facilitated gradual, persistent, but cumulatively significant environmental improvements in the uranium production sector. Cameco's uranium mining and processing facilities exemplify these improvements. These improvements can be expected to continue, supporting our argument of Cameco's environmental sustainability.

    Although sheep milk production is a significant sector for the European Mediterranean countries, it shows serious competitiveness gaps. Minimizing the ecological impacts of dairy sheep farming systems could represent a key factor for farmers to bridging the gaps in competitiveness of such systems and also obtaining public incentives. However, scarce is the knowledge about the environmental performance of Mediterranean dairy sheep farms. The main objectives of this paper were (i) to compare the environmental impacts of sheep milk production from three dairy farms in Sardinia (Italy), characterized by different input levels, and (ii) to identify the hotspots for improving the environmental performances of each farm, by using a Life Cycle Assessment (LCA) approach. The LCA was conducted using two different assessment methods: Carbon Footprint-IPCC and ReCiPe end-point. The analysis, conducted "from cradle to gate", was based on the functional unit 1 kg of Fat and Protein Corrected Milk (FPCM). The observed trends of the environmental performances of the studied farming systems were similar for both evaluation methods. The GHG emissions revealed a little range of variation (from 2.0 to 2.3 kg CO2-eq per kg of FPCM) with differences between farming systems being not significant. The ReCiPe end-point analysis showed a larger range of values and environmental performances of the low-input farm were significantly different compared to the medium- and high-input farms. In general, enteric methane emissions, field operations, electricity and production of agricultural machineries were the most relevant processes in determining the overall environmental performances of farms. Future research will be dedicated to (i) explore and better define the environmental implications of the land use impact category in the Mediterranean sheep farming systems, and (ii) contribute to revising and improving the existing LCA dataset for Mediterranean farming systems.

    Retrieval of negative emotional memories is often accompanied by the experience of stress. Upon retrieval, a memory trace can temporarily return into a labile state, where it is vulnerable to change. An unresolved question is whether post-retrieval stress may affect the strength of declarative memory in humans by modulating the reconsolidation process. Here, we tested in two experiments whether post-reactivation stress may affect the strength of declarative memory in humans. In both experiments, participants were instructed to learn neutral, positive and negative words. Approximately 24h later, participants received a reminder of the word list followed by exposure to the social evaluative cold pressor task (reactivation/stress group, nexp1=20; nexp2=18) or control task (reactivation/no-stress group, nexp1=23; nexp2=18). An additional control group was solely exposed to the stress task, without memory reactivation (no-reactivation/stress group, nexp1=23; nexp2=21). The next day, memory performance was tested using a free recall and a recognition task. In the first experiment we showed that participants in the reactivation/stress group recalled more words than participants in the reactivation/no-stress and no-reactivation/stress group, irrespective of valence of the word stimuli. Furthermore, participants in the reactivation/stress group made more false recognition errors. In the second experiment we replicated our observations on the free recall task for a new set of word stimuli, but we did not find any differences in false recognition. The current findings indicate that post-reactivation stress can improve declarative memory performance by modulating the process of reconsolidation. This finding contributes to our understanding why some memories are more persistent than others. Copyright © 2014. Published by Elsevier Ltd.

    Full Text Available Panela (jaggery or non-centrifuged sugar is a natural food product characterized by its high nutritional value and sweetening power. In the department of Santander, Colombia, the transfor-mation of sugarcane juice into jaggery is carried out mainly in handcrafted sugar mills, which generate a permanent source of employment for rural families. However, according to the results obtained in this study, it should be mentioned that under the current conditions of artisanal production, this agricultural activity involves great physical effort and considerable risk to the workers` health. In addition, it causes significant negative environmental impacts during the production process, standing out changes in the atmospheric composition, microclimatic changes, and pollution of water resources. In order to contribute to the sustainability of the jaggery- production sector in the department of Santander, a qualitative diagnosis of biotic, abiotic and anthropological impacts generated by the production of artisanal jaggery are presented. The current situation of the national jaggery industry and the production process, from cutting sugarcane to the packaging of the final product are described. Identified impacts are characterized and some recommendations to achieve environmentally sustainable production process are provided.

    Organic agriculture has developed rapidly in China since the 1990s, driven by the increasing domestic and international demand for organic products. Quantification of the environmental benefits and production performances of organic agriculture on a national scale helps to develop sustainable high yielding agricultural production systems with minimum impacts on the environment. Data of organic production for 2013 were obtained from a national survey organized by the Certification and Accreditation Administration of China. Farming performance and environmental impact indicators were screened and indicator values were defined based on an intensive literature review and were validated by national statistics. The economic (monetary) values of farming inputs, crop production and individual environmental benefits were then quantified and integrated to compare the overall performances of organic vs. conventional agriculture. In 2013, organically managed farmland accounted for approximately 0.97% of national arable land, covering 1.158 million ha. If organic crop yields were assumed to be 10%-15% lower than conventional yields, the environmental benefits of organic agriculture (i.e., a decrease in nitrate leaching, an increase in farmland biodiversity, an increase in carbon sequestration and a decrease in greenhouse gas emissions) were valued at 1921 million RMB (320.2 million USD), or 1659 RMB (276.5 USD) per ha. By reducing the farming inputs, the costs saved was 3110 million RMB (518.3 million USD), or 2686 RMB (447.7 USD) per ha. The economic loss associated with the decrease in crop yields from organic agriculture was valued at 6115 million RMB (1019.2 million USD), or 5280 RMB (880 USD) per ha. Although they were likely underestimated because of the complex relationships among farming operations, ecosystems and humans, the production costs saved and environmental benefits of organic agriculture that were quantified in our study compensated substantially for the

    Global agricultural feeds over 7 billion people, but is also a leading cause of environmental degradation. Understanding how alternative agricultural production systems, agricultural input efficiency, and food choice drive environmental degradation is necessary for reducing agriculture’s environmental impacts. A meta-analysis of life cycle assessments that includes 742 agricultural systems and over 90 unique foods produced primarily in high-input systems shows that, per unit of food, organic systems require more land, cause more eutrophication, use less energy, but emit similar greenhouse gas emissions (GHGs) as conventional systems; that grass-fed beef requires more land and emits similar GHG emissions as grain-feed beef; and that low-input aquaculture and non-trawling fisheries have much lower GHG emissions than trawling fisheries. In addition, our analyses show that increasing agricultural input efficiency (the amount of food produced per input of fertilizer or feed) would have environmental benefits for both crop and livestock systems. Further, for all environmental indicators and nutritional units examined, plant-based foods have the lowest environmental impacts; eggs, dairy, pork, poultry, non-trawling fisheries, and non-recirculating aquaculture have intermediate impacts; and ruminant meat has impacts ∼100 times those of plant-based foods. Our analyses show that dietary shifts towards low-impact foods and increases in agricultural input use efficiency would offer larger environmental benefits than would switches from conventional agricultural systems to alternatives such as organic agriculture or grass-fed beef.

  10. Philosophiam profiteri or on Derrida's "declarative engagement"

    Directory of Open Access Journals (Sweden)

    Savić Mile V.

    2003-01-01

    Full Text Available In this paper the author reconstructs the meaning of Derrida's concept of "declarative engagement". He shows that Derrida revives the modern idea of the "engaged intellectual" and even develops it in a radical, prophetic/messianic form. The final consequence of such a position, in the opinion of the author, is a paradoxical coupling of political decisionism with social escapism, which renews in a specific way the nostalgia for the "heroic role" of the Marxist intellectual vanguard. This is a major reason for Derrida's popularity in Serbia, it is argued, but can also be taken as the starting point for an analysis of the problem of responsibility of engaged intellectuals.

  11. Productivity and environmental regulations. A long run analysis of the Swedish industry

    Energy Technology Data Exchange (ETDEWEB)

    Braennlund, Runar

    2008-01-15

    The aim with this study is to evaluate the potential effects on productivity development in the Swedish manufacturing industry due to changes in environmental regulations over a long time period. The issue is closely related to the so called Porter hypothesis, i.e. whether environmental regulations (of the right kind) that usually is associated with costs triggers mechanisms that enhances efficiency and productivity that finally outweighs the initial cost increase. To test our hypothesis we use historical data spanning over the period 1913-1999 for the Swedish manufacturing sector. The model used is a two stage model were the total factor productivity is calculated in the first stage, and is then used in a second stage as the dependent variable in a regression analysis where one of the independent variables is a measure of regulatory intensity. The results show that the productivity growth has varied considerably over time. The least productive period was the second world war period, whereas the period with the highest productivity growth was the period after the second world war until 1970. Development of emissions follows essentially the same path as productivity growth until 1970. After 1970, however, there is a decoupling in the sense that emissions are decreasing, both in absolute level and as emissions per unit of value added. A rather robust conclusion is that there is no evident relationship between environmental regulations and productivity growth. One explanation is that regulations and productivity actually is unrelated. Another potential explanation is that the regulatory measure used does not capture perceived regulations in a correct way

    2009-04-01

    Full Text Available Sustainability assessments were carried out in small-holders’ farms in four territories where productive arrangements have been organized for production of minor oleaginous crops under the Brazilian biodiesel program. The study aimed at checking local impacts of the biodiesel productive chains at the rural establishment scale, and promoting the environmental performance of the selected farms, henceforth proposed as sustainable management demonstration units. Assessments were carried out with the APOIA-NovoRural system, which integrates 62 objective and quantitative indicators related to five sustainability dimensions: i Landscape Ecology, ii Environmental Quality (Atmosphere, Water and Soil, iii Socio-cultural Values, iv Economic Values and v Management and Administration. The main results point out that, in general, the ecological dimensions of sustainability, that is, the Landscape Ecology and Atmosphere, Water, and Soil quality indicators, show adequate field conditions, seemingly not yet negatively affected by increases in chemical inputs and natural resources use predicted as important potential impacts of the agro-energy sector. The Economic Values indicators have been favorably influenced in the studied farms, due to a steadier demand and improved prices for the oleaginous crops. On the other hand, valuable positive consequences expected for favoring farmers’ market insertion, such as improved Socio-cultural Values and Management & Administration indicators, are still opportunities to be materialized. The Environmental Management Reports issued to the farmers, based on the presented sustainability assessment procedures, offer valuable documentation and communication means for consolidating the organizational influence of the local productive arrangements studied. These productive arrangements were shown to be determinant for the selection of crop associations and diversification, as well as for the provision of technical assistance

Furthermore, including in the analysis an economic evaluation, from the perspective of an integrated life cycle approach, appears nowadays as a fundamental improvement. In particular, Life Cycle Costing (LCC, is a method that could integrate financial data and cost information with metrics of life cycle approaches. In this study, LCA in conjunction with LCC methods were used, with the aim to evaluate the main cost drivers—environmental and economic—of five widely diffused and market-valued agricultural productions (organic tomato and pear, integrated wheat, apple and chicory and to combine the results in order to understand the long-term externalities impacts of agricultural productions. Data obtained in local assessment show a wide margin of improvement of resources management at farms level in the short-term, but also allow for the investigation of future effects of environmental impacts not expressed in product price on the market. Reaching a real sustainable model for agriculture could be a value added approach firstly for farmers, but also for all the people who live in rural areas or use agricultural products.

    This paper assumes that consumers are willing to pay an extra premium for a good if it has a low impact on the environment. We examine if a little dose of such idealistic behavior has a large impact on the market equilibrium, and to what extent it can replace the environmental regulation. The analysis is carried out in a model with product differentiation, where consumers differ in their preferences for product quality. Consumers' willingness to pay the environmental premium may be uniformly or non-uniformly distributed. Green consumerism will only be modestly influential in both cases, despite the fact that product differentiation leads to relaxed competition and increased profits, and thereby creates leverage.

    Full Text Available This study presents a practical impact assessment method for the adoption of technology innovations at Pectens In vitro Fertilization Laboratory in Rio de Janeiro State, Brazil. To fulfill the system framework requirements, focused on reproductive and productive enterprises, field visits and interview with the laboratory executive director were carried out. Considering the pectens production activities, 24 socio-environmental indicators were developed and the impact indices were automatically calculated by the system’s spreadsheets. General performance index for the pectens reproduction activities indicated an important contribution of technological innovations for the sustainable production of the In vitro Fertilization Laboratory. The employed method was considered as appropriate for evaluations of sustainability at this agribusiness activity, dealing with indicators as tools in order to identify possible risks for negative impacts. Those indicators include aspects beyond those commonly presented by environmental impact assessments, and were capable to provide adequate management and sustainable development for the studied Organization.

  16. Socio-Environmental Impact Assessment of Oleaginous Crops for Biodiesel Production in Brazil

    2007-06-01

    Full Text Available Socio-environmental impact assessments were carried out on oleaginous crops for biodiesel production under the context of expanding demand in five regions of Brazil. The study brought together representatives of the main interest groups in Delphi-type workshops. Major impacts are related with increases in demand for inputs, resources, and energy, with potential risks on water quality and habitat conservation. In some instances, management practices may improve soil quality, favoring habitats recovery. Crop intensification is expected to bring important contributions for farmer capacitation, income generation and sources diversity, as well as improved management and administration. Institutional especially designed local productive arrangements offer the best options for fostering sustainable development and avoiding environmental degradation risks, under the scenario of expanding demand on oleaginous crops for biodiesel production.

    The environment during seed production has major impacts on the behaviour of progeny seeds. It can be shown that for annual plants temperature perception over the whole life history of the mother can affect the germination rate of progeny, and instances have been documented where these affects cross whole generations. Here we discuss the current state of knowledge of signal transduction pathways controlling environmental responses during seed production, focusing both on events that take place in the mother plant and those that occur directly as a result of environmental responses in the developing zygote. We show that seed production environment effects are complex, involving overlapping gene networks active independently in fruit, seed coat, and zygotic tissues that can be deconstructed using careful physiology alongside molecular and genetic experiments. © The Author 2016.

    2013-05-01

    Full Text Available The industry of construction products plays an important role in Europe in promoting the sustainability of the built environment in a life cycle perspective. Within the framework of the European initiatives for a sustainable competitiveness, manufacturers are interested in promoting a life cycle approach along the building chain. However both, institutions and building operators, in general still have to go a long way on designing and applying a sustainable and competitive industrial policy. This paper aims to describe the European background, the regulatory framework, identifying gaps and the actions to be undertaken to promote a market for sustainable products and sustainable buildings. In particular this paper deals with the assessment and communication of the environmental performance of construction products between the operators in the building chain, as a prerequisite for the sustainability of the built environment, and outlines the strategies to implement a proper evaluation and communication process.

    Reuse and valorisation of fish by-products is a key process for marine resources conservation. Usually, fishmeal and oil processing factories collect the by-products generated by fishing port and industry processing activities, producing an economical benefit to both parts. In the same way, different added-value products can be recovered by the valorisation industries whereas fishing companies save the costs associated with the management of those wastes. However, it is important to estimate the advantages of valorisation processes not only in terms of economic income, but also considering the environmental impacts. This would help to know if the valorisation of a residue provokes higher impact than other waste management options, which means that its advantages are probably not enough for guarantying a sustainable waste reuse. To that purpose, there are several methodologies to evaluate the environmental impacts of processes, including those of waste management, providing different indicators which give information on relevant environmental aspects. In the current study, a comparative environmental assessment between a valorisation process (fishmeal and oil production) and different waste management scenarios (composting, incineration and landfilling) was developed. This comparison is a necessary step for the development and industrial implementation of these processes as the best alternative treatment for fish by-products. The obtained results showed that both valorisation process and waste management treatments presented similar impacts. However, a significant benefit can be achieved through valorisation of fish by-products. Additionally, the implications of the possible presence of pollutants were discussed.

    Full Text Available Concrete is a major material used in the construction industry that emits a large amount of substances with environmental impacts during its life cycle. Accordingly, technologies for the reduction in and assessment of the environmental impact of concrete from the perspective of a life cycle assessment (LCA must be developed. At present, the studies on LCA in relation to greenhouse gas emission from concrete are being carried out globally as a countermeasure against climate change. However, the studies on the impact of the substances emitted in the concrete production process on acidification and eutrophication are insufficient. As such, assessing only a single category of environmental impact may cause a misunderstanding about the environmental friendliness of concrete. The substances emitted in the concrete production process have an impact not only on global warming but also on acidification and eutrophication. Acidification and eutrophication are the main causes of air pollution, forest destruction, red tide phenomena, and deterioration of reinforced concrete structures. For this reason, the main substances among those emitted in the concrete production process that have an impact on acidification and eutrophication were deduced. In addition, an LCA technique through which to determine the major emissions from concrete was proposed and a case analysis was carried out. The substances among those emitted in the concrete production process that are related to eutrophication were deduced to be NOx, NH3, NH4+, COD, NO3−, and PO43−. The substances among those emitted in the concrete production process that are related to acidification, were found to be NOx, SO2, H2S, and H2SO4. The materials and energy sources among those input into the concrete production process, which have the biggest impact on acidification and eutrophication, were found to be coarse aggregate and fine aggregate.

    The objective of this Memorandum is to provide a background document for the Danish Environmental Protection Agency (EPA) for use in assessing the impact of the EuP Directive 2005/32/EC of 6 July 2005. Firstly, it aims to highlight the areas of general environmental impact affected by the directive and shall assist the EPA in prioritising the focus, efforts and instruments to be applied in relation to the implementation of the EuP directive in Denmark. Secondly, it aims at extracting and highlighting horizontal themes from the product oriented policy adopted by the European Commission. The conclusions have been derived by the authors and do not necessarily represent the views of the EPA. However, it is the intention that the conclusions can be used as guidance for selecting the strategic focus points. Many aspects of energy-using products (EuPs) have a negative impact on the environment (emissions to air including greenhouse gases, to soil, water, and energy consumption, etc.). The Council and the European Parliament adopted a Commission proposal for a Directive on establishing a framework for setting Eco-design requirements (e.g. energy efficiency) for all energy using products in the residential, tertiary, and industrial sectors. The Commission launched an invitation to tender for 20 preparatory studies corresponding to the major categories of Energy using Products. The studies provide the Commission with the necessary information background to prepare for the next phases, the impact assessment, the consultation with the Eco-design Forum and a draft implementing measures. References to all the Preparatory Studies are found in section 20. The background papers produced in the preparatory studies describes relevant environmental impact issues, but the conclusions are often focused on energy aspects only. Hence, the Danish EPA is interested in a wider assessment and medium to long-term perspectives of the product groups in terms of total environmental impact

    2001-06-01

    We have developed a 'microscopy channel' to advertise a unique set of on-line scientific instruments and to let users join a particular session, perform an experiment, collaborate with other users, and collect data for further analysis. The channel is a collaborative problem solving environment (CPSE) that allows for both synchronous and asynchronous collaboration, as well as flow control for enhanced scalability. The flow control is a declarative feature that enhances software functionality at the experimental scale. Our testbed includes several unique electron and optical microscopes with applications ranging from material science to cell biology. We have built a system that leverages current commercial CORBA services, Web Servers, and flow control specifications to meet diverse requirements for microscopy and experimental protocols. In this context, we have defined and enhanced Instrument Services (IS), Exchange Services (ES), Computational Services (CS), and Declarative Services (DS) that sit on top of CORBA and its enabling services (naming, trading, security, and notification) IS provides a layer of abstraction for controlling any type of microscope. ES provides a common set of utilities for information management and transaction. CS provides the analytical capabilities needed for online microscopy. DS provides mechanisms for flow control for improving the dynamic behavior of the system.

    The purpose of this work was to investigate incentives and barriers to fuel ethanol production from biomass in the U.S. during the past decade (2000-2010). In particular, we examine the results of policies and economic conditions during this period by way of cellulosic ethanol activity in four selected states with the potential to produce different types of feedstocks (i.e., sugar, starch, and cellulosic crops) for ethanol production (Florida, California, Hawaii, and Iowa). Two of the four states, Iowa and California, currently have commercial ethanol production facilities in operation using corn feedstocks. While several companies have proposed commercial scale facilities in Florida and Hawaii, none are operating to date. Federal and state policies and incentives, potential for feedstock production and conversion to ethanol and associated potential environmental impacts, and environmental regulatory conditions among the states were investigated. Additionally, an analysis of proposed and operational ethanol production facilities provided evidence that a combination of these policies and incentives along with the ability to address environmental issues and regulatory environment and positive economic conditions all impact ethanol production. The 2000-2010 decade saw the rise of the promise of cellulosic ethanol. Federal and state policies were enacted to increase ethanol production. Since the initial push for development, expansion of cellulosic ethanol production has not happened as quickly as predicted. Government and private funding supported the development of ethanol production facilities, which peaked and then declined by the end of the decade. Although there are technical issues that remain to be solved to more efficiently convert cellulosic material to ethanol while reducing environmental impacts, the largest barriers to increasing ethanol production appear to be related to government policies, economics, and logistical issues. The numerous federal and state

    To summarize, all children interacted with the experimenter and actively participated in the imitation task. There was evidence of improvement in performance from baseline to recall as would be expected with attention to, and memory for, the actions that were modeled by the experimenter. All participants evidenced a decrease in performance as the difficulty of the task increased, as would be expected. When the maltreated children were compared to the nonmaltreated children in a 2-group design, there was no statistically significant difference in performance. However, when the maltreated group was divided into two subtypes of either neglected or abused, and performance was compared in a 3-group design, it was revealed that the neglected children experienced deficits in performance relative to abused children. For production of target actions, the neglected children's performance trended toward significance when compared to the nonmaltreated children's performance. However, there was no significant difference between the performance of the abused children and the nonmaltreated children for either production of target actions or productions of ordered pairs. The children in this longitudinal study were assessed previously at 12 months of age in a mother-child play situation (Valentino et al., 2006). Interactions during structured play between mother and child were evaluated for maternal directives and child responses. Interestingly, the difference in social interactions that was most reliable was the finding that the abused children imitated their mothers more often than did the nonmaltreated children. There was no difference between the imitative behaviors of the neglected children and the abused or nonmaltreated children. The researchers note that by imitating their mothers, the abused children might be attempting to prevent further abusive incidents. Limit setting behaviors of the mothers in response to child initiations were positively related to the children

  7. Implementation plan for the new production reactor capacity environmental impact statement

    International Nuclear Information System (INIS)

    1989-12-01

    The US Department of Energy (DOE) proposed to site, construct, and operate new production reactor (NPR) capacity intended primarily to produce tritium and secondarily to produce plutonium for the US nuclear weapons program. DOE studies show that this new capacity is needed to ensure reliable maintenance of the nation's nuclear weapons stockpile. It also is essential that these necessary nuclear materials be produced in a safe and environmentally sound manner. The DOE has determined that this proposed action constitutes a major federal action that may significantly affect the quality of the human environment; therefore, the DOE will prepare an environmental impact statement (EIS) to assess the potential impacts of the proposed action and reasonable alternatives on the human and natural environment. The EIS will be prepared in accordance with the National Environmental Policy Act of 1969, as implemented in regulations promulgated by the Council on Environmental Quality (CEQ). This EIS implementation plan (IP) includes a description of the proposed action, descriptions of alternatives, a summary of EIS assumptions, a list of environmental issues to be considered in the EIS (including those identified during public scoping activities), a list of proposed agency consultations, a schedule for EIS preparation and related activities, and an annotated outline for the EIS. It is the Department's intent that the EIS on the NPR capacity will serve as the programmatic National Environmental Policy Act (NEPA) review of modernization of DOE defense nuclear materials production of tritium and plutonium. The Department is currently developing a NEPA compliance strategy for modernization of the remainder of the nuclear weapons production complex, which will reference the EIS on NPR capacity. 7 refs., 8 tabs

    Highlights: ► Study of 12 bioenergy generation pathways as to environmental and economic aspects. ► LCA focused on the GWP, acidification, eutrophication, cumulative energy demand. ► Economic analysis determined electricity production costs based on annuity method. ► Wood-based plants have the best characteristics from environmental point of view. ► Wood-based plants have lowest electricity production costs, biogas plants make gain. - Abstract: This study analyses the use of liquid, solid and gaseous biomass for power generation in Germany with respect to the Renewable Energy Sources Act (EEG), a significant policy instrument for promoting electricity generation based on renewable energy sources. The aim is the identification of bioenergy conversion pathways that have a low environmental impact and are cost-effective. To achieve this objective several research steps were undertaken, including a life-cycle analysis (LCA), economic analysis and the determination of the CO 2 abatement costs. Besides, the authors show and discuss how a simplification of the environmental assessment by considering only the impact category greenhouse gases or the application of different calculation methodologies (i.e. allocation rules between electricity and heat produced) can affect the results. Overall the results show that the use of solid (wood) and gaseous biomass pathways causes both the lowest environmental impacts and electricity production costs when used for electricity generation. The choice of the modelling and calculation methodology may significantly influence the outcome (i.e. application of an exergetic allocation increases the environmental burden related to electricity generation). The lowest CO 2 -abatement costs were determined for the biodegradable waste pathway.

  9. Warheads and Fissile Materials:Declarations and Counting

    Sutcliffe, W.G.

    1991-01-01

    This paper reviews some of the issues about verifying the dismantlement of nuclear warheads and controlling nuclear materials in the context of arms control objectives. It is asserted that information about the stockpiles of nuclear warheads and materials is necessary to analyze the impacts and verification requirements of arms control measures including warhead dismantlement and fissile material controls. It is proposed that the US and the Soviets engage in a series of declarations about their stockpiles of nuclear weapons and materials. It is also asserted that currently it is more important to verify that warheads are retired to safe, secure facilities than to verify their dismantlement. It is proposed that production of new or rebuilt warheads be limited to less than the number retired each year. Verifying the number of new and rebuilt warheads deployed and the number retired avoids many of the difficulties in verifying dismantlement and material controls

    2009-04-01

    Food production and consumption cause significant environmental burdens during the product life cycles. As a result of intensive development and the changing social attitudes and behaviors in the last century, the agrofood sector is the highest resource consumer after housing in the EU. This paper is part of an effort to estimate environmental impacts associated with life cycles of the agrofood chain, such as primary energy consumption, water exploitation, and global warming. Life cycle assessment is used to investigate the production of the following citrus-based products in Italy: essential oil, natural juice, and concentrated juice from oranges and lemons. The related process flowcharts, the relevant mass and energy flows, and the key environmental issues are identified for each product. This paper represents one of the first studies on the environmental impacts from cradle to gate for citrus products in order to suggest feasible strategies and actions to improve their environmental performance.

    Contemporary research into socio-cognitive foundations of organizational learning tends to disregard the distinction between declarative and non-declarative knowledge. By reviewing the literature from organizational learning research and cognitive psychology we explain that this distinction is crucial. We describe the foundations of organizational learning by referring to models that consider the interplay between individual and collective knowledge-related processes in organizations. We highlight the existence of a research gap resulting from the finding that these approaches have widely neglected the existence of different types of knowledge. We then elaborate on characteristics of declarative and non-declarative knowledge in general, consider organizations as structures of distributed cognition, and discuss the relationship between organizational knowledge and practice. Subsequently, we examine the role of declarative and non-declarative knowledge in the context of organizational learning. Here, we analyze (1) the cognitive and social mechanisms underlying the development of declarative and non-declarative knowledge within structures of distributed cognition; and (2) the relationship between alterations in declarative and non-declarative types of knowledge on the one hand and changes in organizational practice on the other. Concluding, we discuss implications of our analysis for organizational learning research. We explain how our integrative perspective may offer starting points for a refined understanding of the sub-processes involved in organizational learning and unlearning and may support a better understanding of practical problems related to organizational learning and change.

    2007-07-01

    Previous research suggests separate neural networks for implicit (non-declarative) and explicit (declarative) memory processes. A core cognitive impairment in mild to moderate Alzheimer's disease (AD) is a pronounced declarative memory and learning deficit with relative preservation of non-declarative memory. Cholinesterase inhibitors has been purported to enhance cognitive function, and previous clinical trials consistently showed that donepezil, a reversible inhibitor of acetylcholinesterase (AChE), led to statistically significant improvements in cognition and patient function. This prospective pilot study is a randomized, double blind, placebo-controlled clinical trial investigating 10 patients with AD. Our purpose was to examine the relationship between declarative and non-declarative capability with particular emphasis on implicit sequence learning. Patients were assessed at baseline and again at 4-weeks. After participants' baseline data were obtained, each was double-blindly randomized to one of two groups: donepezil or placebo. At baseline participants were tested with two outcome measures (Serial Reaction Time Task, Alzheimer's Disease Assessment Scale-Cognitive Subscale). Participants were given either 5 mg donepezil or an identically appearing placebo to be taken nightly for 4 weeks (28 tablets), and then retested. The donepezil group demonstrated a greater likelihood of increases in both non-declarative and declarative processes. The placebo group was mixed without clearly definable trends or patterns. When the data were examined for coincidental changes in the two outcome measures together they are suggestive of a benefit from donepezil treatment for non-declarative and declarative processes.

  15. Environmental degradation, global food production, and risk for large-scale migrations

    1994-01-01

    This paper attempts to estimate to what extent global food production is affected by the ongoing environmental degradation through processes, such as soil erosion, salinization, chemical contamination, ultraviolet radiation, and biotic stress. Estimates have also been made of available opportunities to improve food production efficiency by, e.g., increased use of fertilizers, irrigation, and biotechnology, as well as improved management. Expected losses and gains of agricultural land in competition with urbanization, industrial development, and forests have been taken into account. Although estimated gains in food production deliberately have been overestimated and losses underestimated, calculations indicate that during the next 30-35 years the annual net gain in food production will be significantly lower than the rate of world population growth. An attempt has also been made to identify possible scenarios for large-scale migrations, caused mainly by rapid population growth in combination with insufficient local food production and poverty. 18 refs, 7 figs, 6 tabs

However, we identify steam turbines and combustion engines for combined heat and power production as potential high performers, while combustion engines that only produce...

  17. Integrated production of sugarcane ethanol and soybean biodiesel: Environmental and economic implications of fossil diesel displacement

    International Nuclear Information System (INIS)

    Souza, Simone P.; Seabra, Joaquim E.A.

    2014-01-01

    Highlights: • Sugarcane sector is responsible for around 4% of the diesel consumption in Brazil. • Soybean biodiesel can reduce the fossil diesel demand in the sugarcane sector. • The local use of biodiesel could reduce logistic problems and environmental burdens. • The sugarcane–soybean integration is likely to improve ethanol life cycle performance. • Fiscal incentives could reduce the economic uncertainties of the integration. - Abstract: The sugarcane industry in Brazil has been considered promising for the production of advanced fuels and bio-based products. However, the sugarcane crop requires high volumes of fossil fuel for cultivation and transport. The use of biodiesel as a diesel substitute could reduce the environmental burdens associated with this high consumption. This work performed a stochastic evaluation of the environmental and economic implications of the integrated production of sugarcane bioethanol and soybean biodiesel, in comparison with the traditional sugarcane-to-ethanol process. The analysis was focused on the states of Goiás, Mato Grosso and São Paulo, where this integration would be particularly attractive. The environmental aspects addressed were the fossil energy use and the GHG emissions in a cradle-to-gate approach. The economic analysis comprised the evaluation of the net present value of an incremental cash flow generated by the soybean production and by the adjacent plants of oil extraction and biodiesel. Results indicate that the integrated system is likely to improve the ethanol environmental performance, especially with regard to the fossil energy use. The integration is economically feasible but highly uncertain; however, it could be significantly improved through fiscal incentives to biodiesel producers, founded on the reduction of fossil energy use and on improvements in logistics. In addition, the proposed model may also assist in the design of other integrated systems applied to the sugarcane sector in Brazil

    Full Text Available Switchgrass displays an excellent potential to serve as a non-food bioenergy feedstock for bioethanol production in China due to its high potential yield on marginal lands. However, few studies have been conducted on the spatial distribution of switchgrass-based bioethanol production potential in China. This study created a land surface process model (Environmental Policy Integrated Climate GIS (Geographic Information System-based (GEPIC model coupled with a life cycle analysis (LCA to explore the spatial distribution of potential bioethanol production and present a comprehensive analysis of energy efficiency and environmental impacts throughout its whole life cycle. It provides a new approach to study the bioethanol productivity and potential environmental impact from marginal lands based on the high spatial resolution GIS data, and this applies not only to China, but also to other regions and to other types of energy plant. The results indicate that approximately 59 million ha of marginal land in China are suitable for planting switchgrass, and 22 million tons of ethanol can be produced from this land. Additionally, a potential net energy gain (NEG of 1.75 x 106 million MJ will be achieved if all of the marginal land can be used in China, and Yunnan Province offers the most significant one that accounts for 35% of the total. Finally, this study obtained that the total environmental effect index of switchgrass-based bioethanol is the equivalent of a population of approximately 20,300, and a reduction in the global warming potential (GWP is the most significant environmental impact.

    Some of the environmental challenges which the uranium production industry faces in the 21st century have been discussed in the paper. They are: the use of the linear non-threshold (LNT) model for radiation protection, the concept of 'controllable dose' as an alternative to the current International Commission on Radiological Protection (ICRP) system of dose limitation, the future of collective dose and the ALARA (As low As Reasonably Achievable) principle and the application of a risk-based framework for managing hazards. The author proposes that, the risk assessment/risk management framework could be used for managing the environmental, safety and decommissioning issues associated with the uranium fuel cycle.

    Obtaining capital is a critical element in the production expansion plans of OPEC member countries. Another issue that may impact the plans is the environmental taxes that may reduce the call on OPEC oil by 5 million b/d in 2000 and about 16 million b/d in the year 2010. This concluding part of a two-part series discusses the expansion possibilities of non-Middle East OPEC members, OPEC's capital requirements, and environmental concerns. Non-Middle East OPEC includes Algeria, Gabon, Indonesia, Libya, Nigeria, and Venezuela
