  1. Industrial Waste

    Christensen, Thomas Højlund

    2011-01-01

    generation rates and material composition as well as determining factors are discussed in this chapter. Characterizing industrial waste is faced with the problem that often only a part of the waste is handled in the municipal waste system, where information is easily accessible. In addition part...... of the industrial waste may in periods, depending on market opportunities and prices, be traded as secondary rawmaterials. Production-specificwaste from primary production, for example steel slag, is not included in the current presentation. In some countries industries must be approved or licensed and as part...... of the system industry has to inform at the planning stage and afterwards in yearly reports on their waste arising and how the waste is managed. If available such information is very helpful in obtaining information about that specific industry. However, in many countries there is very little information...

  3. Hazardous industrial waste management

    Quesada, Hilda; Salas, Juan Carlos; Romero, Luis Guillermo

    2007-01-01

    The appropriate managing of hazardous wastes is a problem little dealed in the wastes management in the country. A search of available information was made about the generation and handling to internal and external level of the hazardous wastes by national industries. It was worked with eleven companies of different types of industrial activities for, by means of a questionnaire, interviews and visits, to determine the degree of integral and suitable handling of the wastes that they generate. It was concluded that exist only some isolated reports on the generation of hazardous industrial wastes and handling. The total quantity of wastes generated in the country was impossible to establish. The companies consulted were deficient in all stages of the handling of their wastes: generation, accumulation and storage, transport, treatment and final disposition. The lack of knowledge of the legislation and of the appropriate managing of the wastes is showed as the principal cause of the poor management of the residues. The lack of state or private entities entrusted to give services of storage, transport, treatment and final disposition of hazardous wastes in the country was evident. (author) [es

  8. Energy from wastes and the private waste contracting industry

    Burnett, J.S.

    1993-01-01

    The focus of this ongoing work is the utilisation of general non hazardous industrial and commercial waste as an energy or fuel source. Whereas much of the existing experience in energy from waste (EFW) is related to municipal solid wastes (MSW), there is very little direct experience with these other waste streams and the shortage of reliable information in this field is notoriously lacking. It is important to have a good understanding of the private waste contracting industry (pwci) in order to establish the conditions under which energy from waste technologies may play an economically and technically feasible role within that industry's development. The Non Fossil Fuel Obligation (NFFO) has encouraged entrepreneurial interest through premium payments for electricity generated from renewable sources. (author)

  10. The problem of industrial wastes

    Hamdan, Fouad

    1998-01-01

    The paper is the result of a feasibility study conducted for the Green peace Office in Lebanon. The overall goal of the study was to work towards implementing a national waste management plan and to combat the import of hazardous wastes from developing countries.The author focuses on the illegal trade of industrial wastes from developed to under developed countries. The trade of toxic wastes causes on environmental pollution. As for Lebanese industries, the main problem is toxic industrial wastes. About 4000 tones/day of domestic wastes are produced in Lebanon. 326000 tones of industrial wastes contain toxic substances are annually produced and wastes growth rate is expected to increase to one million tone/year in 2010. A disaster is threatening Lebanon especially that no policy were taken to deal with the huge growth of wastes. This problem affect on population health especially in the region of Bourj Hammoud. Analysis of ground water in the region of Chekka, confirm the existence of water pollution caused by toxic materials In addition, analysis of Petro coke used in the National Lebanese Cement Industry, contain a high rate of Polycyclic Aromatic Hydrocarbons. Green peace is aware of the danger of wastes in air, water and land pollution and preventing environment of any source of pollution this will certainly lead to a sustainable development of the country

  12. EXOPOLYSACCHARIDES SYNTHESIS ON INDUSTRIAL WASTES

    T.P.

    2016-04-01

    Full Text Available Data from the literature and our own studies on the synthesis of microbial exopolysaccharides on various industrial waste (food industry, agricultural sector, biodiesel production, etc. are reviewed here. Utilization of industrial waste to obtain exopolysaccharides will solve not only the problem of secondary raw materials accumulation, but also will reduce the costs of the biosynthesis of practically valuable metabolites. In addition, some kinds of waste have a number of advantages compared to traditional carbohydrate substrates: aside from environmental health benefits, there are technological ones, like the presence of growth factors. There is also no need to use anti-foam substances and substrate sterilization in the latter case.

  14. Final waste classification and waste form technical position papers

    1983-05-01

    The waste classification technical position paper describes overall procedures acceptable to NRC staff which may be used by licensees to determine the presence and concentrations of the radionuclides listed in section 61.55, and thereby classifying waste for near-surface disposal. This technical position paper also provides guidance on the types of information which should be included in shipment manifests accompanying waste shipments to near-surface disposal facilities. The technical position paper on waste form provides guidance to waste generators on test methods and results acceptable to NRC staff for implementing the 10 CFR Part 61 waste form requirements. It can be used as an acceptable approach for demonstrating compliance with the 10 CFR Part 61 waste structural stability criteria. This technical position paper includes guidance on processing waste into an acceptable stable form, designing acceptable high-integrity containers, packaging cartridge filters, and minimizing radiation effects on organic ion-exchange resins. The guidance in the waste form technical position paper may be used by licensees as the basis for qualifying process control programs to meet the waste form stability requirements, including tests which can be used to demonstrate resistance to degradation arising from the effects of compression, moisture, microbial activity, radiation, and chemical changes. Generic test data (e.g., topical reports prepared by vendors who market solidification technology) may be used for process control program qualification where such generic data is applicable to the particular types of waste generated by a licensee

    NONE

    1994-12-01

    The objective of this report is to present the generic reference design of a centralized waste processing and storage facility (WPSF) intended for countries producing small but significant quantities of liquid and solid radioactive wastes. These wastes are generated through the use of radionuclides for research, medical, industrial and other institutional activities in IAEA Member States that have not yet developed the infrastructure for a complete nuclear fuel cycle. The WPSF comprises two separate buildings. The first, for receiving and processing waste from the producers, includes the necessary equipment and support services for treating and conditioning the waste. The second building acts as a simple but adequate warehouse for storing a ten year inventory of the conditioned waste. In developing the design, it was a requirement of the IAEA that options for waste management techniques for each of the waste streams should be evaluated, in order to demonstrate that the reference design is based on the most appropriate technology.

    1986-01-01

    The US Department of Energy manages wastes that are both chemically hazardous and radioactive. These mixed wastes are often unique and many have national security implications. Management practices have evolved over the more than forty years that the Department and its predecessor agencies have been managing these wastes, both in response to better understanding of the hazards involved and in response to external, regulatory influences. The Department has recently standarized its waste management practices and has initited an R and D program to address priority issues identified by its operating contractor organizations. The R and D program is guided by waste management strategy that emphasizes reduction of human exposure to hazardous wastes in the environment, reduction of the amount and toxicity of wastes generated, treatment of wastes that are generated to reduce volumes and toxicities, and identification of alternatives to land disposal of wastes that remain hazardous following maximum practicable treatment

  1. Industrial management of radioactive wastes

    Lavie, J.M.

    1984-01-01

    This article deals with the present situation in France concerning radioactive waste management. For the short and medium term, that is to say processing and disposal of low and medium level radioactive wastes, there are industrial processes giving all the guarantees for a safe containment, but improvements are possible. For the long term optimization of solution requires more studies of geologic formations. Realization emergency comes less from the waste production than the need to optimize the disposal techniques. An international cooperation exists. All this should convince the public opinion and should develop planning and realization [fr

  3. Waste Management in Industrial Construction: Investigating Contributions from Industrial Ecology

    Larissa A. R. U. Freitas

    2017-07-01

    Full Text Available The need for effective construction waste management is growing in importance, due to the increasing generation of construction waste and to its adverse impacts on the environment. However, despite the numerous studies on construction waste management, recovery of construction waste through Industrial Symbiosis and the adoption of other inter-firm practices, comprised within Industrial Ecology field of study, have not been fully explored. The present research aims to investigate Industrial Ecology contributions to waste management in industrial construction. The waste management strategies adopted in two industrial construction projects in Brazil are analyzed. The main waste streams generated are identified, recycling and landfilling diversion rates are presented and waste recovery through Industrial Symbiosis is discussed. A SWOT analysis was carried out. Results demonstrate that 9% of the waste produced in one of the projects was recovered through Industrial Symbiosis, while in the other project, waste recovery through Industrial Symbiosis achieved the rate of 30%. These data reveal Industrial Symbiosis’ potential to reduce landfilling of industrial construction wastes, contributing to waste recovery in construction. In addition, results show that industrial construction projects can benefit from the following synergies common in Industrial Ecology place-based approaches: centralized waste management service, shared waste management infrastructure and administrative simplification.

    Large areas of Latvia are contaminated with industrial waste: metallurgical slag, fly-ash, etching refuse, peat, and coal ash as well as glass waste which often contain dangerous substances. From the environmental point of view this waste should be neutralised. As this waste also contains valuable chemical compounds, it can be considered as a raw material for the generation of new materials. One method of utilisation is to produce recycled materials - street plates, decorative tiles, or floor tiles. Dense sintered glassceramics with a water uptake of 0.34-3.23 wt.%, a final density of 2.93-3.05 g/cm{sup 3}, and a bending strength of 80-96 MPa have been created from industrial waste. The mast chemically durable glassceramics contained clay additions. Thus, the material containing only waste had a durability (mass loss) of 3.02% in 0.1 N HCl, while the composition containing 30% clay addition had a durability of 0.2% in 0.1 N HCl.

    Bortoluzzi, D.; Oliveira Fillho, J.; Uggioni, E.; Bernardin, A.M.

    2009-01-01

    This paper deals with the study of the vitrification mechanism as an inertization method for industrial wastes contaminated with heavy metals. Ashes from coal (thermoelectric), wastes from mining (fluorite and feldspar) and plating residue were used to compose vitreous systems planed by mixture design. The chemical composition of the wastes was determined by XRF and the formulations were melted at 1450 deg C for 2h using 10%wt of CaCO 3 (fluxing agent). The glasses were poured into a mold and annealed (600 deg C). The characteristic temperatures were determined by thermal analysis (DTA, air, 20 deg C/min) and the mechanical behavior by Vickers microhardness. As a result, the melting temperature is strongly dependent on silica content of each glass, and the fluorite residue, being composed mainly by silica, strongly affects Tm. The microhardness of all glasses is mainly affected by the plating residue due to the high iron and zinc content of this waste. (author)

  7. Reduced waste generation technical work plan

    1987-05-01

    The United States Department of Energy has established policies for avoiding plutonium losses to the waste streams and minimizing the generation of wastes produced at its nuclear facilities. This policy is evidenced in DOE Order 5820.2, which states ''Technical and administrative controls shall be directed towards reducing the gross volume of TRU waste generated and the amount of radioactivity in such waste.'' To comply with the DOE directive, the Defense Transuranic Waste Program (DTWP) supports and provides funding for specific research and development tasks at the various DOE sites to reduce the generation of waste. This document has been prepared to give an overview of current and past Reduced Waste Generation task activities which are to be based on technical and cost/benefit factors. The document is updated annually, or as needed, to reflect the status of program direction. Reduced Waste Generation (RWG) tasks encompass a wide range of goals which are basically oriented toward (1) avoiding the generation of waste, (2) changing processes or operations to reduce waste, (3) converting TRU waste into LLW by sorting or decontamination, and (4) reducing volumes through operations such as incineration or compaction

  13. Technical evaluation of proposed Ukrainian Central Radioactive Waste Processing Facility

    Gates, R.; Glukhov, A.; Markowski, F.

    1996-06-01

    This technical report is a comprehensive evaluation of the proposal by the Ukrainian State Committee on Nuclear Power Utilization to create a central facility for radioactive waste (not spent fuel) processing. The central facility is intended to process liquid and solid radioactive wastes generated from all of the Ukrainian nuclear power plants and the waste generated as a result of Chernobyl 1, 2 and 3 decommissioning efforts. In addition, this report provides general information on the quantity and total activity of radioactive waste in the 30-km Zone and the Sarcophagus from the Chernobyl accident. Processing options are described that may ultimately be used in the long-term disposal of selected 30-km Zone and Sarcophagus wastes. A detailed report on the issues concerning the construction of a Ukrainian Central Radioactive Waste Processing Facility (CRWPF) from the Ukrainian Scientific Research and Design institute for Industrial Technology was obtained and incorporated into this report. This report outlines various processing options, their associated costs and construction schedules, which can be applied to solving the operating and decommissioning radioactive waste management problems in Ukraine. The costs and schedules are best estimates based upon the most current US industry practice and vendor information. This report focuses primarily on the handling and processing of what is defined in the US as low-level radioactive wastes

  14. Open absorption heat pump for waste heat utilization in the forest industry. A study of technical and economic potential; Oeppen absorptionsvaermepump foer uppgradering av spillvaerme fraan skogsindustrin. Studie av teknisk och ekonomisk potential

    Westermark, Mats; Vidlund, Anna

    2006-02-15

    Waste heat from the forest industry is mainly humid air or humid flue gases with somewhat too low dew point for direct use as district heating or for other qualified purposes. Upgrading of the temperature by heat pumps is thus often necessary for the full use of the waste heat. This study evaluates an open absorption heat, based on hygroscopic condensation. The hygroscopic condenser has the potential to replace mechanical heat pumps or conventional absorption heat pumps (based on lithium bromide) for the upgrading of heat from humid gases. The goal for the project is to evaluate technology and potential for an open absorption heat pump for heat recovery from humid gases in the forest industry. In an open heat pump the humid gas is brought in direct contact with the hygroscopic liquid (whereas a conventional heat pump uses an intermediate circuit with evaporation of water in the evaporator). The direct contact makes it possible to recover the heat at a higher temperature than the dew point of the humid gas without the use of evaporator. The target group for the study is the forest industry and its suppliers of technology and knowledge. The study has been carried out in cooperation with representatives from the forest industry and from suppliers of equipment. The study shows that the forest industry has good potential to upgrade waste heat from humid air to district heating. The waste heat can be extracted from various humid gases such as exit air from paper machines, wood driers, green liquid quenchers and flue gases from soda boilers, mesa kilns, bark-fired boilers and gas engines. Hygroscopic condensation is considered to give economic and environmental advantages compared to conventional absorption heat pumps due to much less consumption of driving heat. An interesting special case is the regeneration of the hygroscopic medium by direct contact with hot flue gases and for this application a patent application has been filed.

  15. The Auburn Engineering Technical Assistance Program investigation of polyvinyl alcohol film developments pertaining to radioactive particle decontamination and industrial waste minimization

    Mole, Tracey Lawrence

    In this work, an effective and systematic model is devised to synthesize the optimal formulation for an explicit engineering application in the nuclear industry, i.e. radioactive decontamination and waste reduction. Identification of an optimal formulation that is suitable for the desired system requires integration of all the interlacing behaviors of the product constituents. This work is unique not only in product design, but also in these design techniques. The common practice of new product development is to design the optimized product for a particular industrial niche and then subsequent research for the production process is conducted, developed and optimized separately from the product formulation. In this proposed optimization design technique, the development process, disposal technique and product formulation is optimized simultaneously to improve production profit, product behavior and disposal emissions. This "cradle to grave" optimization approach allowed a complex product formulation development process to be drastically simplified. The utilization of these modeling techniques took an industrial idea to full scale testing and production in under 18 months by reducing the number of subsequent laboratory trials required to optimize the formula, production and waste treatment aspects of the product simultaneously. This particular development material involves the use of a polymer matrix that is applied to surfaces as part of a decontamination system. The polymer coating serves to initially "fix" the contaminants in place for detection and ultimate elimination. Upon mechanical entrapment and removal, the polymer coating containing the radioactive isotopes can be dissolved in a solvent processor, where separation of the radioactive metallic particles can take place. Ultimately, only the collection of divided solids should be disposed of as nuclear waste. This creates an attractive alternative to direct land filling or incineration. This philosophy also

  1. Technical Safety Requirements for the Waste Storage Facilities

    Larson, H L

    2007-01-01

    This document contains Technical Safety Requirements (TSR) for the Radioactive and Hazardous Waste Management (RHWM) WASTE STORAGE FACILITIES, which include Area 612 (A612) and the Decontamination and Waste Treatment Facility (DWTF) Storage Area at Lawrence Livermore National Laboratory (LLNL). The TSRs constitute requirements regarding the safe operation of the WASTE STORAGE FACILITIES. These TSRs are derived from the Documented Safety Analysis for the Waste Storage Facilities (DSA) (LLNL 2006). The analysis presented therein determined that the WASTE STORAGE FACILITIES are low-chemical hazard, Hazard Category 2 non-reactor nuclear facilities. The TSRs consist primarily of inventory limits and controls to preserve the underlying assumptions in the hazard and accident analyses. Further, appropriate commitments to safety programs are presented in the administrative controls sections of the TSRs. The WASTE STORAGE FACILITIES are used by RHWM to handle and store hazardous waste, TRANSURANIC (TRU) WASTE, LOW-LEVEL WASTE (LLW), mixed waste, California combined waste, nonhazardous industrial waste, and conditionally accepted waste generated at LLNL as well as small amounts from other U.S. Department of Energy (DOE) facilities, as described in the DSA. In addition, several minor treatments (e.g., drum crushing, size reduction, and decontamination) are carried out in these facilities. The WASTE STORAGE FACILITIES are located in two portions of the LLNL main site. A612 is located in the southeast quadrant of LLNL. The A612 fenceline is approximately 220 m west of Greenville Road. The DWTF Storage Area, which includes Building 693 (B693), Building 696 Radioactive Waste Storage Area (B696R), and associated yard areas and storage areas within the yard, is located in the northeast quadrant of LLNL in the DWTF complex.

  4. Some technical writing skills industry needs

    Smith, F. R.

    1981-01-01

    It is suggested that engineers and other technical students be taught three classes of skills in technical writing. First, "Big Picture Things", which includes: the importance of clear writing, the wide scope of writing, the wide scope of writing tasks that will be faced in industry, and the principles of organization of technical materials such as; how to analyze, classify, partition, and interpret. Second, "Writing Procedures", which encompasses: how to get words on paper efficiently and team-write. Third, "Writing Details", in which two considerations are important: how to achieve precision in the use of language and the aspects of style. Three problems in style are cited: the problem of sentence transition, overuse of attributive adjectives, and verbosity in paragraph structure. The most important thing in technical writing is considered to be functionality, economy and clarity.

    In this paper, the treatment by irradiation of some surface active agents (SAA) contained in aqueous solutions and industrial wastes, has been shown. Studies were carried out on selected SAA, namely Rokafenol N-6 and Pretepon G-extra, representatives of nonionic and anionic SAA, respectively. The aqueous solutions of these compounds were irradiated in radiation chamber, at the Institute of Applied Radiation Chemistry, in Lodz Polytechnic. Co/sup 60/ was used as a source of radiation. The kinetics and degree of destruction of these compounds at the doses ranging from 2 kGy to 110 kGy were investigated. The study was extended to attempts to remove SAA from textile effluents. Reduction of other parameters of contamination, including measurements of toxicity, were also evaluated.

  8. Challenges of technical cooperation in the petroleum industry

    Al-Athel, S.A.

    1992-01-01

    The need and prospects for international technical cooperation in the petroleum industry are reviewed. Since it directly affects the survival of the inhabitants of the planet, environmental protection is a field that could enjoy maximum international cooperation; oil spills, product environmental hazards, waste minimization and disposal and oil field fires are the main areas identified. Technical cooperation in other areas of the industry, namely exploration, production, oil field development, refining and petrochemicals, may involve some controversy. Attention is drawn to the conflicting interests of multinational companies, who almost completely control the technology of these activities, and host developing countries. It is advocated that arrangements involving technology transfer should make provision for the growth of indigenous technology. (UK)

  11. Technical specifications for mechanical recycling of agricultural plastic waste

    Briassoulis, D.; Hiskakis, M.; Babou, E.

    2013-01-01

    Highlights: • Technical specifications for agricultural plastic wastes (APWs) recycling proposed. • Specifications are the base for best economical and environmental APW valorisation. • Analysis of APW reveals inherent characteristics and constraints of APW streams. • Thorough survey on mechanical recycling processes and industry as it applies to APW. • Specifications for APW recycling tested, adjusted and verified through pilot trials. - Abstract: Technical specifications appropriate for the recycling of agricultural plastic wastes (APWs), widely accepted by the recycling industry were developed. The specifications establish quality standards to be met by the agricultural plastics producers, users and the agricultural plastic waste management chain. They constitute the base for the best economical and environmental valorisation of the APW. The analysis of the APW streams conducted across Europe in the framework of the European project “LabelAgriWaste” revealed the inherent characteristics of the APW streams and the inherent constraints (technical or economical) of the APW. The APW stream properties related to its recycling potential and measured during pilot trials are presented and a subsequent universally accepted simplified and expanded list of APW recycling technical specifications is proposed and justified. The list includes two sets of specifications, applied to two different quality categories of recyclable APW: one for pellet production process (“Quality I”) and another one for plastic profile production process (“Quality II”). Parameters that are taken into consideration in the specifications include the APW physical characteristics, contamination, composition and degradation. The proposed specifications are focused on polyethylene based APW that represents the vast majority of the APW stream. However, the specifications can be adjusted to cover also APW of different materials (e.g. PP or PVC) that are found in very small quantities

  12. Industrial ecology: Environmental chemistry and hazardous waste

    Manahan, S.E. [Univ. of Missouri, Columbia, MO (United States). Dept. of Chemistry

    1999-01-01

    Industrial ecology may be a relatively new concept -- yet it`s already proven instrumental for solving a wide variety of problems involving pollution and hazardous waste, especially where available material resources have been limited. By treating industrial systems in a manner that parallels ecological systems in nature, industrial ecology provides a substantial addition to the technologies of environmental chemistry. Stanley E. Manahan, bestselling author of many environmental chemistry books for Lewis Publishers, now examines Industrial Ecology: Environmental Chemistry and Hazardous Waste. His study of this innovative technology uses an overall framework of industrial ecology to cover hazardous wastes from an environmental chemistry perspective. Chapters one to seven focus on how industrial ecology relates to environmental science and technology, with consideration of the anthrosphere as one of five major environmental spheres. Subsequent chapters deal specifically with hazardous substances and hazardous waste, as they relate to industrial ecology and environmental chemistry.

    A survey is given of the application of radioisotopes in technical diagnosis of industrial plants. Proceeding from the economic importance and the state of the art of radioisotope applications, the principles of tracer techniques are outlined including topical examples of application such as passage of coal through a steam generator, wear in impact crashing of coal, wear and corrosion in pipelines, testing the effective cross section of pipes, and investigations of microstructures. Limits and restrictions of applications are briefly discussed

  15. The management of industrial wastes in hydrology; La gestion des dechets industriels en hydrologie

    Elbaz-Seboun, V.

    1998-07-08

    The industrial wastes are made of different kind of wastes: the inert wastes, the banal wastes (municipal wastes), the special wastes containing noxious elements with respect to human health and environment, and the radioactive wastes. Each industry generates its own effluents (sludges from water treatment plants and leachates from rubbish dumps). The main water pollutions are due to the fermentescible organic matters, nitrates and heavy metals from the industrial waste waters. The aim of the public water agencies is to better protect the environment and to give help to the industrialists in the management of their wastes: reduction at the source, selective collection, valorization, transportation and processing. Non-valorizable wastes must be processed: physico-chemical and biological processing (bio-filtering, coagulation-flocculation, membranes and industrial gases), incineration (organic wastes), disposal in class 1 technical burial centres after stabilization (ultimate wastes). Since July 2002, only the ultimate wastes will be disposed off and all class 2 and 3 dumps must have been rehabilitated. This work is divided into 2 parts: part 1 gives a presentation of the different types of industrial wastes and of their management (origin of wastes, effluents, heavy metals, environmental impact, legal aspects, wastes management, valorization). The second part describes the different processes for the treatment of industrial wastes (conventional processes, physico-chemical and biological processes, incineration, tipping, processing of radioactive wastes).

  16. Solid waste management in Khartoum industrial area

    Elsidig, N. O. A.

    2004-05-01

    This study was conducted in Khartoum industrial area (KIA). The study discusses solid waste generation issues in KIA as well as solid waste collection, storage, transport and final disposal methods. A focus on environmental impact resulting from the accumulation of solid waste was presented by reviewing solid waste management in developed as well as developing countries starting from generation to final disposal. Environmental health legislation in Sudan was investigated. The study covers all the (eight) industrial sub-sectors presented in KIA. The main objective of the study is to assess the situation of solid waste in KIA. To fulfill the objectives of the study the researcher deemed it necessary to explore problems related to solid waste generation and solid waste arrangement with special emphasis on final disposal methods. Practically, 31 (thirty-one) factories representing the different industrial sub-sectors in KIA were studied. This represents 25% of the total number of factories located in KIA. Data were obtained by, questionnaires, interviews and observations mainly directed to concerned officials, solid waste workers, pickers and brokers. Obtained data were stored, coded, tabulated and analyzed using the computer systems (excel and SPSS programmes). The obtained results should clear deficiency in the management of solid waste which led to great environmental deterioration in KIA and neighboring residential areas. The environment in studied area is continuously polluted due to high pollution loads and unproved solid waste management. In order to maintain health environment operating factories have to pretreated their solid waste according to the recognized standards and waste minimization techniques such as recycling and re use should be widely applied, moreover, running crash programme for environmental sanitation in Khartoum state should be expanded and improved to include special characteristics of solid waste from industries. Finally, increase awareness

  17. Scientific and technical challenges of radioactive waste management

    Vira, J.

    1996-01-01

    In spite of considerable spending on research and technical development, the management of nuclear wastes continues to be a difficult issue in public decision making. The nuclear industry says that it has safe solutions for the ultimate disposal of nuclear wastes, but the message has not really got through to the public at large. Although communications problems reflect the general stigmatization of nuclear power, there are obvious issues in safety and performance assessment of nuclear waste disposal which evade scientific resolution. Any scientist is concerned for his personal credibility must respect the rules and limits of scientific practice, but the intriguing question is whether he would not do better to address the layman's worries about radioactive substances? The discussion in this paper points out the intricacies of the distinction between scientific proof and judgement, with emphasis on safety assessment for nuclear waste disposal. Who are the final arbitrators? In a democratic society it is probably those who vote.Building confidence in expert judgements is a challenge for waste managers and scientists. The media may create their own 'experts', whose only necessary credential is the trust of their audience, but scientific judgements must stand the test of time.'Confidence building' is currently a key word on the whole nuclear waste management scene, and confidence in science and scientists is certainly needed for any progress towards practical implementation of plans. The means for building confidence in the decision-making process are probably different from those applied for science and scientists. (author)

  18. Assessment of industrial liquid waste management in Omdurman Industrial Area

    Elnasri, R. A. A.

    2003-04-01

    This study was conducted mainly to investigate the effects of industrial liquid waste on the environment in the Omdurman area. Various types of industries are found around Omdurman. According to the ISC the major industries are divided into eight major sub-sectors, each sub-sector is divided into types of industries. Special consideration was given to the liquid waste because of its effects. In addition to the available data, personal observation supported by photographs, laboratory analyses were carried on the industrial effluents. The investigated parameters in the analysis were, BOD, COD, O and G, Cr, TDS, TSS, pH, temp and conductivity. Interviews were conducted with waste handling workers in the industries, in order to assess the effects of industrial pollution. The results obtained showed that pollutants produced by all the factories were found to exceed the accepted levels of the industrial pollution control. The effluents disposed of in the sites allotted by municipal authorities have adverse effects on the surrounding environment and public health and amenities. Accordingly the study recommends that the waste water must be pretreated before being disposed of in site allotted by municipal authorities. Develop an appropriate system for industrial waste proper management. The study established the need to construct a sewage system in the area in order to minimize the pollutants from effluents.

  4. Technical and economic evaluation of controlled disposal options for very low level radioactive wastes

    Robinson, P.J.; Vance, J.N.

    1990-08-01

    Over the past several years, there has been considerable interest by the nuclear industry in the Nuclear Regulatory Commission (NRC) explicitly defined an activity level in plant waste materials at which the radiological impacts would be so low as to be considered Below Regulatory Concern (BRC). In January 1989, Electric Power Research Institute (EPRI) completed an extensive industry research effort to develop the technical bases for establishing criteria for the disposal of very low activity wastes in ordinary disposal facilities. The Nuclear Management and Resources Council (NUMARC), with assistance from the Edison Electric Institute (EEI) and the Electric Power Research Institute (EPRI), drafted a petition titled: ''Petition for Rulemaking Regarding Disposal of Below Regulatory Concern Radioactive Wastes from Commercial Nuclear Power Plants.'' Subsequent to the industry making a final decision for submittal of the drafted BRC petition, EPRI was requested to evaluate the technical and economic impact of six BRC options. These options are: take no action in pursuing a BRC waste exemption, petition the NRC for authorization to disposal of any BRC waste in any ordinary disposal facility, limit disposal of BRC waste to the nuclear power plant site, limit disposal of BRC waste to the nuclear power plant site and other utility owned property, petition for a mixed waste exemption, and petition for single waste stream exemptions in sequence (i.e. soil, followed by sewage sludge, etc.). The petition and technical bases were written to support the disposal of any BRC waste type in any ordinary disposal facility. These documents do not provide all of the technical and economic information needed to completely assessment the BRC options. This report provides the technical and economic basis for a range of options concerning disposal of very low activity wastes. 3 figs., 20 tabs

    Physicochemical and technological basics for reprocessing of uranium industry wastes of Northern Tajikistan shows that the most perspective for reprocessing is Chkalovsk tailing's wastes. Engineer and geological condition and content of radionuclides in wastes are investigated. It is determined that considered wastes by radioactivity are low-active and they can be reprocessed with the purpose of U 3 O 8 production. Grinding, crumbling, thickening and etc. operations are decreased during the wastes reprocessing process. Uranium output is more than 90%. Optimal parameters of products extraction from uranium mining industry wastes are found. Characteristics of mine and technical waters of uranium industry wastes are studied. Characteristics of mine and technical waters of Kiik-Tal and Istiklol city (former Taboshar) showed the expediency of uranium oxide extraction from them. The reasons for non-additional recovery extraction from dumps of State Enterprise 'Vostokredmet' by classical methods of uranium leaching are studied. Kinetics of sulfuric leaching of residues from anthropogenic deposit of Map 1-9 (Chkalovsk city) is investigated. Carried out investigations are revealing the flow mechanism process of residues' sulfuric leaching and enable selection of radiation regime of U 3 O 8 production. Kinetics of sorption process of uranium extraction from mine and technical waters of uranium industry wastes is studied. High sorption properties of apricot's shell comparing to other sorbents are revealed. Basic process flow diagram for reprocessing of uranium tailing wastes is developed as well as diagram for uranium extraction from mine and technical waters from uranium industry wastes which consists of the following stages: acidification, sorption, burning, leaching, sedimentation, filtration, drying.

  7. Industrial Water Waste, Problems and the Solution

    Alif Noor Anna

    2004-01-01

    Full Text Available Recently, the long term development in Indonesia has changed agricultural sector to the industrial sector. This development can apparently harm our own people. This is due to the waste that is produced from factories. The waste from various factories seems to have different characteristics. This defference encourages us to be able to find out different of methods of managing waste so that cost can be reduced, especially in water treatment. In order that industrial development and environmental preservation can run together in balance, many institutions involved should be consider, especially in the industrial chain, the environment, and human resource, these three elements can be examined in terms of their tolerance to waste.

  8. Industrial aspects of radioactive waste management in Western Europe

    Marcus, F.R.; Seynaeve, F.

    1977-01-01

    In 1980 there will be about 120 nuclear power reactors with 70,000 MWe in operation in Western Europe, and this number will be doubled by 1985, when the nuclear capacity in operation is expected to be 180,000 MWe. Predictions are made of the waste management requirements resulting from this nuclear expansion. Until a few years ago waste from nuclear research and from the use of isotopes in medicine has been the dominating source. Now there is a much larger proportion from the day to day operation of nuclear power reactors. Waste amounts from reprocessing of spent reactor fuel will rise more slowly. Waste production in other fuel cycle industries is relatively insignificant. There will be around 30 reactors and other nuclear plants to take out of operation in Western Europe around 1990. The large-scale handling of these wastes calls for overall management schemes, based on clear policies for storage and disposal. Questions are identified which have to be answered within the next few years in order to allow the orderly development of such large-scale waste management. These questions deal with: (i) rules and regulations, (ii) new technical evidence, (iii) administrative frameworks and responsibilities. Several areas of waste management are well suited to commercial waste operating firms, already established at present in a number of European countries. The scope for waste operators may include waste transportation, operating of own or government owned treatment and storage installations, and the carrying out of disposal operations. In the paper, development needs originally suggested by the Foratom waste study group will be discussed in the light of a late 1976 review to be carried through by European industry

  10. Industrial Hazardous Waste Management In Egypt-the baseline study: An Updated review

    Farida M, S.

    1999-01-01

    Increased industrialization over the past decades in Egypt has resulted in an increased and uncontrolled generation of industrial hazardous waste. This was not accompanied by any concerted efforts to control these wastes. Consequently, no system for handling or disposing of industrial wastes, in general, and industrial hazardous wastes, in specific, exists. In 1993, a baseline report was formulated to assess the overall problem of industrial hazardous waste management in Egypt. Consequently, recommendations for priority actions were identified and the main components of a national hazardous waste system under the provision of Law 4/ 1994 were presented. This paper provides an updated review of this report in light of the proposed technical, legal and institutional guidelines to help in the realization of such a needed waste management system in Egypt

  11. Renewable energy recovery through selected industrial wastes

    Zhang, Pengchong

    Typically, industrial waste treatment costs a large amount of capital, and creates environmental concerns as well. A sound alternative for treating these industrial wastes is anaerobic digestion. This technique reduces environmental pollution, and recovers renewable energy from the organic fraction of those selected industrial wastes, mostly in the form of biogas (methane). By applying anaerobic technique, selected industrial wastes could be converted from cash negative materials into economic energy feed stocks. In this study, three kinds of industrial wastes (paper mill wastes, brown grease, and corn-ethanol thin stillage) were selected, their performance in the anaerobic digestion system was studied and their applicability was investigated as well. A pilot-scale system, including anaerobic section (homogenization, pre-digestion, and anaerobic digestion) and aerobic section (activated sludge) was applied to the selected waste streams. The investigation of selected waste streams was in a gradually progressive order. For paper mill effluents, since those effluents contain a large amount of recalcitrant or toxic compounds, the anaerobic-aerobic system was used to check its treatability, including organic removal efficiency, substrate utilization rate, and methane yield. The results showed the selected effluents were anaerobically treatable. For brown grease, as it is already well known as a treatable substrate, a high rate anaerobic digester were applied to check the economic effect of this substrate, including methane yield and substrate utilization rate. These data from pilot-scale experiment have the potential to be applied to full-scale plant. For thin stillage, anaerobic digestion system has been incorporated to the traditional ethanol making process as a gate-to-gate process. The performance of anaerobic digester was applied to the gate-to-gate life-cycle analysis to estimate the energy saving and industrial cost saving in a typical ethanol plant.

  12. Waste energy recovery in the industry in the ECE region

    1985-01-01

    In the ECE region industry accounts for about 44 per cent of total final energy consumption, 50-55 per cent of which is ''lost''. Since the early 1970s the efficiency of energy use has improved by 5 or 6 percentage points. The potential for further cost-effective savings is estimated at 10 to 20 percentage points, depending on the type of industrial activity, kind of waste energy, availability of outlets, investment strategies, awareness of the significantly improved technical possibilities and degree of co-operation between energy specialists and production engineers, equipment manufacturers, and industrial sectors at the national and international levels. The present publication argues the case for secondary energy recovery (SER) by end-users and international co-operation in technical, economic, environmental and methodological fields. It is based on data compiled by the secretariat of the Economic Commission for Europe on 1 June 1984 and given general distribution. Refs, figs and tabs

  13. Industrial Waste Landfill IV upgrade package

    1994-01-01

    The Y-12 Plant, K-25 Site, and ORNL are managed by DOE's Operating Contractor (OC), Martin Marietta Energy Systems, Inc. (Energy Systems) for DOE. Operation associated with the facilities by the Operating Contractor and subcontractors, DOE contractors and the DOE Federal Building result in the generation of industrial solid wastes as well as construction/demolition wastes. Due to the waste streams mentioned, the Y-12 Industrial Waste Landfill IV (IWLF-IV) was developed for the disposal of solid industrial waste in accordance to Rule 1200-1-7, Regulations Governing Solid Waste Processing and Disposal in Tennessee. This revised operating document is a part of a request for modification to the existing Y-12 IWLF-IV to comply with revised regulation (Rule Chapters 1200-1-7-.01 through 1200-1-7-.08) in order to provide future disposal space for the ORR, Subcontractors, and the DOE Federal Building. This revised operating manual also reflects approved modifications that have been made over the years since the original landfill permit approval. The drawings referred to in this manual are included in Drawings section of the package. IWLF-IV is a Tennessee Department of Environmental and Conservation/Division of Solid Waste Management (TDEC/DSWM) Class 11 disposal unit

  14. Trends in U.S.A. on environmental assessment of the common industrial wastes

    Yamauchi, Kiyoshi

    1994-01-01

    In Japan, the waste materials are divided to two parts of radioactive wastes and common wastes according to the law on treatment and cleaning of the wastes, and the latter is divided further to two parts of life type wastes and business type wastes. Among them, a part of wastes called the industrial wastes in the business wastes causes some troubles. In Japan, maintenance of approval level of the wastes treatment was conducted by selection of treating method due to feature of the wastes, selection of treating matters due to the treating site and method, and environmental assessment of each treatment project program. However, in U.S.A., regulation on environmental impact due to various human actions has been executed since 1960, and environmental assessment is controlled by a law. And, regulations on the wastes, the treating facilities and the formed pollution were also determined by laws. Furthermore, technical field of the environmental assessment is already executed in U.S.A. but some parts are not in Japan. On the evaluation method, there are some differences between in U.S.A. and in Japan, but are some common points in technical informations, estimating methods and so on, where future technical cooperations and movements between them in environmental assessment on both common industrial wastes and high level radioactive wastes.

  16. MOX fuel fabrication: Technical and industrial developments

    Lebastard, G.; Bairiot, H.

    1990-01-01

    The plutonium available in the near future is generally estimated rather precisely on the basis of the reprocessing contracts and the performance of the reprocessing plants. A few years ago, decision makers were convinced that a significant share of this fissile material would be used as the feed material for fast breeder reactors (FBRs) or other advanced reactors. The facts today are that large reprocessing plants are coming into commercial operations: UP3 and soon UP2-800 and THORP, but that FBR deployment is delayed worldwide. As a consequence, large quantities of plutonium will be recycled in light water reactors as mixed oxide (MOX) fuels. MOX fuel technology has been properly demonstrated in the past 25 years. All specific problems have been addressed, efficient fabrication processes and engineering background have been implemented to a level of maturity which makes MOX fuel behaving as well as Uranium fuel. The paper concentrates on todays MOX fabrication expertise and presents the technical and industrial developments prepared by the MOX fuel fabrication industry for this last decade of the century

    Raphael, M.A.

    1995-01-01

    Industrial waste and industrial waste management are described, with economic considerations and recommendations for an industrial waste management program applicable in Lebanon. Different conceptual systems for industrial waste management are presented: - The O effluent industrial plant, an electric manufacturing plant with mass and energy balance. - The industrial complexing concept where environmentally balanced and compatible, industries are located in one area. Waste effluents from one plant can be used as raw material for another plant. - A standard petroleum waste recovery plant to cope with local requirements complementary to the proposed sanitary waste treatment plant in Lebanon. Major sources of industrial waste in Lebanon are analyzed:local process industries, hospitals, laboratories, petroleum industries and power generation, are the major sources cited. For each source the level of treatment is indicated. Tables and appendixes on waste treatment and management along with the ISO 9000 series are presented. 10 refs. 3 figs

  20. Clearance level and industrial waste management

    Asano, Toichi

    1999-01-01

    Defining the clearance level enables the radioactive waste with lower radioactivity than a certain level to be the general industrial waste and therefore consideration for public acceptance is essential. For this, it is necessary to understand laws concerning not only atomic power and radioactivity but also disposal and cleaning of general waste. It is also necessary that the waste below the clearance level should be as much as possible handled in the modern common concept of recycling of resources. In 1996, the weight of industrial waste was about 400 million tons, of which 40% was disposed by burning and dehydration, 39% was re-used and 21% was subjected to the final disposal like reclamation. Reduction, re-use and recycling of the generated waste are required for making the society with recycling of resources. Scrap concrete materials below the clearance level of 0.6 million tons are estimated to be generated by dismantling the light water reactor of 1 million kW output and profitable technology for recycling the scrap is under investigation.

    2008-07-01

    Acoustic pollution is an environmental problem that is becoming increasingly more important in our society. Likewise, the accumulation of generated waste and the need for waste management are also becoming more and more pressing. In this study we describe a new material--called PROUSO--obtained from industrial wastes. PROUSO has a variety of commercial and engineering, as well as building, applications. The main raw materials used for this environmentally friendly material come from slag from the aluminium recycling process, dust from the marble industry, foundry sands, and recycled expanded polystyrene from recycled packaging. Some natural materials, such as plastic clays, are also used. To obtain PROUSO we used a conventional ceramic process, forming new mineral phases and incorporating polluted elements into the structure. Its physical properties make PROUSO an excellent acoustic and thermal insulation material. It absorbs 95% of the sound in the frequency band of the 500 Hz. Its compressive strength makes it ideal for use in ceramic wall building.

    The French Planning Act of 28 June 2006 prescribed that a reversible repository in a deep geological formation be chosen as the reference solution for the long-term management of high-level and intermediate-level long-lived radioactive waste. It also entrusted the responsibility of further studies and design of the repository (named Cigeo) upon the French Radioactive Waste Management Agency (Andra), in order for the review of the creation-license application to start in 2015 and, subject to its approval, the commissioning of the repository to take place in 2025. Andra is responsible for siting, designing, implementing, operating the future geological repository, including operational and long term safety and waste acceptance. Nuclear operators (Electricite de France (EDF), AREVA NC, and the French Commission in charge of Atomic Energy and Alternative Energies (CEA) are technically and financially responsible for the waste they generate, with no limit in time. They provide Andra, on one hand, with waste packages related input data, and on the other hand with their long term industrial experiences of high and intermediate-level long-lived radwaste management and nuclear operation. Andra, EDF, AREVA and CEA established a cooperation agreement for strengthening their collaborations in these fields. Within this agreement Andra and the nuclear operators have defined an industrial program for waste management. This program includes the waste inventory to be taken into account for the design of the Cigeo project and the structural hypothesis underlying its phased development. It schedules the delivery of the different categories of waste and defines associated flows. (authors)

    Treatment of chemical industrial wastewater from building and construction chemicals factory and plastic shoes manufacturing factory was investigated. The two factories discharge their wastewater into the public sewerage network. The results showed the wastewater discharged from the building and construction chemicals factory was highly contaminated with organic compounds. The average values of COD and BOD were 2912 and 150 mg O 2 /l. Phenol concentration up to 0.3 mg/l was detected. Chemical treatment using lime aided with ferric chloride proved to be effective and produced an effluent characteristics in compliance with Egyptian permissible limits. With respect to the other factory, industrial wastewater was mixed with domestic wastewater in order to lower the organic load. The COD, BOD values after mixing reached 5239 and 2615 mg O 2 /l. The average concentration of phenol was 0.5 mg/l. Biological treatment using activated sludge or rotating biological contactor (RBe) proved to be an effective treatment system in terms of producing an effluent characteristic within the permissible limits set by the law

  18. Waste energy boosts tomato industry at distillery

    McColl, J

    1989-04-01

    A trial project aimed at using waste hot water from the cooling process at a Scottish whisky distillery to heat a glasshouse for tomato production is described. Later developments have involved the installation of a waste heat boiler to make use of the heat from the still burner flue gases. Steam from the boiler is used within the distillery and to supplement the glasshouse system. The payback within the distillery industry has been excellent, but tomato production, though continuing, was adversely affected by severe cutbacks in distillery production in the early eighties. Recently further significant savings have been made in the distillery industry by the installation of a regenerative burner in one of the stills and thermo-compressors in the cooling tower condensers to produce low pressure steam which can be fed back into the system.

  20. Technical area status report for waste destruction and stabilization

    Dalton, J.D.; Harris, T.L.; DeWitt, L.M.

    1993-08-01

    The Office of Environmental Restoration and Waste Management (EM) was established by the Department of Energy (DOE) to direct and coordinate waste management and site remediation programs/activities throughout the DOE complex. In order to successfully achieve the goal of properly managing waste and the cleanup of the DOE sites, the EM was divided into five organizations: the Office of Planning and Resource Management (EM-10); the Office of Environmental Quality Assurance and Resource Management (EM-20); the Office of Waste Operations (EM-30); the Office of Environmental Restoration (EM-40); and the Office of Technology and Development (EM-50). The mission of the Office of Technology Development (OTD) is to develop treatment technologies for DOE's operational and environmental restoration wastes where current treatment technologies are inadequate or not available. The Mixed Waste Integrated Program (MWIP) was created by OTD to assist in the development of treatment technologies for the DOE mixed low-level wastes (MLLW). The MWIP has established five Technical Support Groups (TSGs) whose purpose is to identify, evaluate, and develop treatment technologies within five general technical areas representing waste treatment functions from initial waste handling through generation of final waste forms. These TSGs are: (1) Front-End Waste Handling, (2) Physical/Chemical Treatment, (3) Waste Destruction and Stabilization, (4) Second-Stage Destruction and Offgas Treatment, and (5) Final Waste Forms. This report describes the functions of the Waste Destruction and Stabilization (WDS) group. Specifically, the following items are discussed: DOE waste stream identification; summary of previous efforts; summary of WDS treatment technologies; currently funded WDS activities; and recommendations for future activities

  1. Does industrial waste taxation contribute to reduction of landfilled waste? Dynamic panel analysis considering industrial waste category in Japan.

    Sasao, Toshiaki

    2014-11-01

    Waste taxes, such as landfill and incineration taxes, have emerged as a popular option in developed countries to promote the 3Rs (reduce, reuse, and recycle). However, few studies have examined the effectiveness of waste taxes. In addition, quite a few studies have considered both dynamic relationships among dependent variables and unobserved individual heterogeneity among the jurisdictions. If dependent variables are persistent, omitted variables cause a bias, or common characteristics exist across the jurisdictions that have introduced waste taxes, the standard fixed effects model may lead to biased estimation results and misunderstood causal relationships. In addition, most existing studies have examined waste in terms of total amounts rather than by categories. Even if significant reductions in total waste amounts are not observed, some reduction within each category may, nevertheless, become evident. Therefore, this study analyzes the effects of industrial waste taxation on quantities of waste in landfill in Japan by applying the bias-corrected least-squares dummy variable (LSDVC) estimators; the general method of moments (difference GMM); and the system GMM. In addition, the study investigates effect differences attributable to industrial waste categories and taxation types. This paper shows that industrial waste taxes in Japan have minimal, significant effects on the reduction of final disposal amounts thus far, considering dynamic relationships and waste categories.

  2. Technical appraisal of the current situation in the field of radioactive waste management

    1985-01-01

    Industrial activities are regarded as safe even though a small risk always exists. The philosophy of radiation protection accepts this and recognises that some level of risk will also be associated with safe radioactive waste management. Therefore the objective of radioactive waste management is to look for a strategy which, taken as a whole, is considered safe and provides an acceptable balance of all the radiological, technical, social, political and economic considerations. The RWMC's appraisal underlines the need for such a balance while concentrating on radiological and technical factors, particularly on the long term safety aspects of radioactive waste management. The fundamental conclusion is that detailed short and long term safety assessments can now be made which give confidence that radiation protection objectives can be met with currently available technology for most waste types, and at a cost which is only a small fraction of the overall cost of nuclear-generated power

  3. Technical report from Radioactive Waste Management Funding and Research Center

  6. Waste management '76 nuclear overview session industry viewpoint

    Carson, A.B.

    1976-01-01

    Lack of firm policy decisions and implementing regulations and program plans related to nuclear fuel cycle by-product wastes has become a major deterrent to progress in the constructive utilization of fission energy. In any event, the mismatch between waste management program accomplishments and perceived requirements has increased rather than decreased over recent years. Multi-agency programs and industry participation as well, at higher levels of effort than in the past, are required and are being initiated, but useful and lasting decisions still are some time off. From industry's viewpoint, all of the agency and industry programs related to waste management must be based on (a) a common view that no constructive activity is going to have zero personnel or environmental impact and that there generally will be a finite level of impact or risk to public health and safety that can be considered acceptable, and (b) consistent and rational consideration of what the levels of impact or risk are that can be considered acceptable in various circumstances. Regulatory requirements finally imposed must be related in some rational way to actual effects and their acceptable levels. Sound bases for timely decisions also require recognition of the fact that ''full and complete demonstration'' is not often really practical or necessary. Demonstration requirements for particular circumstances must be clearly defined and related to functional importance, extent of supporting technology and experience and other such rational factors. Finally, it is recognized that there are nontechnical issues the resolution of which are just as necessary to progress as the technical ones. However, such issues should not be allowed to lead to decisions or actions which are phenomenologically unsound or technically unsupported. After all, you might as well fall flat on your face as lean too far over backward

  7. Position paper on irradiated fuel and waste management. The Achille's heel of the nuclear industry?

    Bonin, Bernard

    2014-01-01

    The management and final disposal of irradiated fuel and nuclear waste is often presented by the media and perceived by the public as being an unsolved problem that restricts the future of nuclear energy. However, the nuclear industry focused on this problem very early on and has developed proven technical solutions. Nuclear energy will continue developing worldwide, in spite of the Fukushima accident. Even in those European countries that have decided to phase-out nuclear energy there is a legacy of nuclear waste that must be dealt with. The scientific and technical expertise needed for waste management already exists. Management decisions must be taken. Now is the time for political courage. (orig.)

  8. Preliminary technical data summary defense waste processing facility stage 2

    1980-12-01

    This Preliminary Technical Data Summary presents the technical basis for design of Stage 2 of the Staged Defense Waste Processing Facility (DWPF). Process changes incorporated in the staged DWPF relative to the Alternative DWPF described in PTDS No. 3 (DPSTD-77-13-3) are the result of ongoing research and development and are aimed at reducing initial capital investment and developing a process to efficiently immobilize the radionuclides in Savannah River Plant (SRP) high-level liquid waste. The radionuclides in SRP waste are present in sludge that has settled to the bottom of waste storage tanks and in crystallized salt and salt solution (supernate). Stage 1 of the DWPF receives washed, aluminum dissolved sludge from the waste tank farms and immobilizes it in a borosilicate glass matrix. The supernate is retained in the waste tank farms until completion of Stage 2 of the DWPF at which time it is filtered and decontaminated by ion exchange in the Stage 2 facility. The decontaminated supernate is concentrated by evaporation and mixed with cement for burial. The radioactivity removed from the supernate is fixed in borosilicate glass along with the sludge. This document gives flowsheets, material and curie balances, material and curie balance bases, and other technical data for design of Stage 2 of the DWPF. Stage 1 technical data are presented in DPSTD-80-38

  9. Conversion of food industrial wastes into bioplastics.

    Yu, P H; Chua, H; Huang, A L; Lo, W; Chen, G Q

    1998-01-01

    The usage of plastics in packaging and disposable products, and the generation of plastic waste, have been increasing drastically. Broader usage of biodegradable plastics in packaging and disposable products as a solution to environmental problems would heavily depend on further reduction of costs and the discovery of novel biodegradable plastics with improved properties. In the authors' laboratories, various carbohydrates in the growth media, including sucrose, lactic acid, butyric acid, valeric acid, and various combinations of butyric and valeric acids, were utilized as the carbon (c) sources for the production of bioplastics by Alcaligenes eutrophus. As the first step in pursuit of eventual usage of industrial food wastewater as nutrients for microorganisms to synthesize bioplastics, the authors investigated the usage of malt wastes from a beer brewery plant as the C sources for the production of bioplastics by microorganisms. Specific polymer production yield by A. Latus DSM 1124 increased to 70% polymer/cell (g/g) and 32 g/L cell dry wt, using malt wastes as the C source. The results of these experiments indicated that, with the use of different types of food wastes as the C source, different polyhydroxyalkanoate copolymers could be produced with distinct polymer properties.

  10. Palisades technical specification conversion from custom to new industry standard

    Foley, D.J.; Young, B.

    1990-01-01

    Consumers Power Company's (CPCo) Palisades plant is in the process of converting from custom technical specifications to the new industry standard, Restructured Standard Technical Specifications (RSTS). Custom technical specifications were the precursor to standard technical specifications, being issued to plants built prior to 1972. In May 1989, each of the four light water reactor owners' groups completed topical reports presenting their version of Restructured Standard Technical Specifications to the Nuclear Regulatory Commission (NRC). After approval of the owners' groups versions of the RSTs by the NRC, individual operating reactors will begin to make the conversion to the RSTS. Each owners' group has designated a lead plant, which will be the first of that vendor type to convert. All of the lead plants currently operate under standard technical specifications. The content of the RSTS was determined by comparing the standard technical specifications with selection criteria specified in the Commissions Interim Policy Statement

  11. Assessment of logistic outlays in industrial solid waste management

    Janusz Grabara

    2014-12-01

    Full Text Available Out of concern for environmental protection is an increasingly common practice. Companies thus have an additional task which is the correct organization of the industrial waste management. This is achieved through the use of logistics processes in industrial waste management, mainly such as warehousing, transport, storage and recovery. These processes involve the formation of logistics costs resulting from waste management. The paper presents a mathematical model for cost of logistics management of industrial waste resulting from the above-mentioned processes. It also shows the interpretation of these costs and the relations between them. The model can increase costefficiency in companies managing industrial waste, while increasing attention to the environment.

  14. The industrial waste landfill of Bonfol (Switzerland)

    Arnold, C.G.; Bentz, R. [Ciba Specialty Chemicals Inc., Basel (Switzerland); Fischer, M.; Huerzeler, R.A.; Matter, B.; Munz, C.D.

    2003-07-01

    The landfill for industrial waste in Bonfol (Switzerland) was installed in 1961 in an waterproof clay pit and was run until 1976 by the bci, the Basel chemical industry, to dispose off their industrial waste originating from chemical production. For the first time in Europe chemical wastes were deposited in a special area selected according to geological criteria. Groundwater and surface waters have been continuously supervised since the beginning of the activities in Bonfol in 1961. After the landfill was totally filled up, it was covered by a clay layer. In the years 1980/81 the monitoring program discovered that the cover of the landfill was leaking and that the pit was slowly filled up with water. Some exfiltrations resulted. It was important to overcome the critical situation by the implementation of immediate measures, e.g. pumping and removal of leachate. Different remediation options were studied at that time, among other the excavation and final disposal of the contents of the landfill. On October 17, 2000 a voluntary agreement between the authorities and bci ws signed. On May 15, 2001, bci presented the result of the study of remedial options. Excavation / incineration in European incinerators or in-situ vitrification, with a suboption excavation/on-site vitrification, were seen as the most promising ones. At the end of 2001 the option of the in-situ vitrification was dropped because of the resulting public and political resistance towards this technology. The remaining options are being evaluated thoroughly at the moment to prepare the basis for a decision on the clean-up project. (orig.)

  15. Characterisation of Radioactive Waste located at Shelter Industrial Site

    Brown, T.D.; Billon, F.; Rudko, V.M.; Batiy, V.G.; Panasyuk, N.I.

    2001-04-01

    As a result of the accident at the unit 4 reactor at the Chernobyl Nuclear Power Plant on the 26 April 1986 there was widespread radioactive contamination of the surrounding area. The area immediately surrounding Unit 4, referred to as the Industrial Site, was very heavily contaminated with fuel and core debris ejected from the reactor. Immediate action was undertaken to reduce the local radiation hazard and mitigate the potential of secondary contamination of the environment. This action involved (a) the removal and collection of fuel fragments (b) removal of the top layer of soil around unit 4 and (c) preparation of a new surface over the Industrial Site. This new surface is referred to colloquially as the Techno-genic Layer. This report provides an overview of a project undertaken for DG-Environment of European Commission by a Consortium consisting of SGN (France) and AEA Technology (UK) working in collaboration with the Organisation, National Academy of Sciences of Ukraine; the Interdisciplinary Scientific and Technical Centre Shelter''. The project consisted of 3 Phases and a total of 14 Tasks. The main purpose of Phase 1 was to review previous work and available information and data on the contamination of the Industrial Site, construction of the Techno-genic Layer, Buttress and Pioneer Walls. Phase 2 was directed at additional measurements being carried out on existing boreholes and core samples to improve and/or substantiate existing information and data. Estimation of likely radioactive waste arisings, recovery procedures and a generalised strategy with indicative costs for the management of the waste was also covered by Phase 2. In Phase 3 new boreholes (3 off) were drilled and subsequently investigated. The justification behind Phase 3 was the desire/need to obtain more reliable information on the so-called high-active waste buried in the Industrial Site. (author)

  18. Melt processing of radioactive waste: A technical overview

    Schlienger, M.E.; Buckentin, J.M.; Damkroger, B.K.

    1997-01-01

    Nuclear operations have resulted in the accumulation of large quantities of contaminated metallic waste which are stored at various DOE, DOD, and commercial sites under the control of DOE and the Nuclear Regulatory Commission (NRC). This waste will accumulate at an increasing rate as commercial nuclear reactors built in the 1950s reach the end of their projected lives, as existing nuclear powered ships become obsolete or unneeded, and as various weapons plants and fuel processing facilities, such as the gaseous diffusion plants, are dismantled, repaired, or modernized. For example, recent estimates of available Radioactive Scrap Metal (RSM) in the DOE Nuclear Weapons Complex have suggested that as much as 700,000 tons of contaminated 304L stainless steel exist in the gaseous diffusion plants alone. Other high-value metals available in the DOE complex include copper, nickel, and zirconium. Melt processing for the decontamination of radioactive scrap metal has been the subject of much research. A major driving force for this research has been the possibility of reapplication of RSM, which is often very high-grade material containing large quantities of strategic elements. To date, several different single and multi-step melting processes have been proposed and evaluated for use as decontamination or recycling strategies. Each process offers a unique combination of strengths and weaknesses, and ultimately, no single melt processing scheme is optimum for all applications since processes must be evaluated based on the characteristics of the input feed stream and the desired output. This paper describes various melt decontamination processes and briefly reviews their application in developmental studies, full scale technical demonstrations, and industrial operations

  2. Industrial waste utilization for foam concrete

    Krishnan, Gokul; Anand, K. B.

    2018-02-01

    Foam concrete is an emerging and useful construction material - basically a cement based slurry with at least 10% of mix volume as foam. The mix usually containing cement, filler (usually sand) and foam, have fresh densities ranging from 400kg/m3 to 1600kg/m3. One of the main drawbacks of foam concrete is the large consumption of fine sand as filler material. Usage of different solid industrial wastes as fillers in foam concrete can reduce the usage of fine river sand significantly and make the work economic and eco-friendly. This paper aims to investigate to what extent industrial wastes such as bottom ash and quarry dust can be utilized for making foam concrete. Foam generated using protein based agent was used for preparing and optimizing (fresh state properties). Investigation to find the influence of design density and air-void characteristics on the foam concrete strength shows higher strength for bottom ash mixes due to finer air void distribution. Setting characteristics of various mix compositions are also studied and adoption of Class C flyash as filler demonstrated capability of faster setting.

  6. Models for waste life cycle assessment: Review of technical assumptions

    Gentil, Emmanuel; Damgaard, Anders; Hauschild, Michael Zwicky

    2010-01-01

    A number of waste life cycle assessment (LCA) models have been gradually developed since the early 1990s, in a number of countries, usually independently from each other. Large discrepancies in results have been observed among different waste LCA models, although it has also been shown that results...... from different LCA studies can be consistent. This paper is an attempt to identify, review and analyse methodologies and technical assumptions used in various parts of selected waste LCA models. Several criteria were identified, which could have significant impacts on the results......, such as the functional unit, system boundaries, waste composition and energy modelling. The modelling assumptions of waste management processes, ranging from collection, transportation, intermediate facilities, recycling, thermal treatment, biological treatment, and landfilling, are obviously critical when comparing...

  7. Evaluating the technical aspects of mixed waste treatment technologies

    Bagaasen, L.M.; Scott, P.A.

    1992-10-01

    This report discusses treatment of mixed wastes which is thought to be more complicated than treatment of either hazardous or radioactive wastes. In fact, the treatment itself is no more complicated: however, the regulations that define acceptability of the final waste disposal system are significantly more entangled, and sometimes in apparent conflict. This session explores the factors that influence the choice of waste treatment technologies, and expands on some of the limitations to their application. The objective of the presentation is to describe the technical factors that influence potential treatment processes and the ramifications associated with particular selections (for example, the generation of secondary waste streams). These collectively provide a framework for making informed treatment process selections

    2008-02-15

    The recovery of solid waste is required by waste legislation, and also by the public. In some industries, however, waste is mostly disposed of in landfills despite of its high recoverability. Practical experiences show that the fast food industry is one example of these industries. A majority of the solid waste generated in the fast food industry is packaging waste, which is highly recoverable. The main research problem of this study was to find out the means of promoting the recovery of packaging waste generated in the fast food industry. Additionally, the goal of this article was to widen academic understanding on packaging waste management in the fast food industry, as the subject has not gained large academic interest previously. The study showed that the theoretical recovery rate of packaging waste in the fast food industry is high, 93% of the total annual amount, while the actual recovery rate is only 29% of the total annual amount. The total recovery potential of packaging waste is 64% of the total annual amount. The achievable recovery potential, 33% of the total annual amount, could be recovered, but is not mainly because of non-working waste management practices. The theoretical recovery potential of 31% of the total annual amount of packaging waste cannot be recovered by the existing solid waste infrastructure because of the obscure status of commercial waste, the improper operation of producer organisations, and the municipal autonomy. The research indicated that it is possible to reach the achievable recovery potential in the existing solid waste infrastructure through new waste management practices, which are designed and operated according to waste producers' needs and demands. The theoretical recovery potential can be reached by increasing the consistency of the solid waste infrastructure through governmental action. (author)

  9. Characteristics and management of infectious industrial waste in Taiwan

    Huang, M.-C.; Lin, Jim Juimin

    2008-01-01

    Infectious industrial waste management in Taiwan is based on the specific waste production unit. In other countries, management is based simply on whether the producer may lead to infectious disease. Thus, Taiwan has a more detailed classification of infectious waste. The advantage of this classification is that it is easy to identify the sources, while the disadvantage lies in the fact that it is not flexible and hence increases cost. This study presents an overview of current management practices for handling infectious industrial waste in Taiwan, and addresses the current waste disposal methods. The number of small clinics in Taiwan increased from 18,183 to 18,877 between 2003 and 2005. Analysis of the data between 2003 and 2005 showed that the majority of medical waste was general industrial waste, which accounted for 76.9%-79.4% of total medical waste. Infectious industrial waste accounted for 19.3%-21.9% of total medical waste. After the SARS event in Taiwan, the amount of infectious waste reached 19,350 tons in 2004, an increase over the previous year of 4000 tons. Waste minimization was a common consideration for all types of waste treatment. In this study, we summarize the percentage of plastic waste in flammable infectious industrial waste generated by medical units, which, in Taiwan was about 30%. The EPA and Taiwan Department of Health have actively promoted different recycling and waste reduction measures. However, the wide adoption of disposable materials made recycling and waste reduction difficult for some hospitals. It has been suggested that enhancing the education of and promoting communication between medical units and recycling industries must be implemented to prevent recyclable waste from entering the incinerator

  12. Industrial aspects of radioactive waste management in Western Europe

    Marcus, F.R.

    1976-01-01

    Various aspects of waste management are discussed from the viewpoint of the nuclear industry. Future amounts of waste generated in the 15 Foratom countries in Western Europe are estimated. Industrial waste questions--as seen by electricity producers, reprocessors, and waste operators--are discussed; questions concerning decommissioning are also dealt with. A number of recommendations for further action, primarily on the part of national authorities and international organizations, are put forward. One conclusion of the study is that there is no reason for waste-management problems to impede the timely development of nuclear energy as a large-scale industrial activity in Western Europe

  13. Development of a master plan for industrial solid waste management

    Karamouz, M.; Zahraie, B.; Kerachian, R.; Mahjouri, N.; Moridi, A.

    2006-01-01

    Rapid industrial growth in the province of Khuzestan in the south west of Iran has resulted in disposal of about 1750 tons of solid waste per day. Most of these industrial solid wastes including hazardous wastes are disposed without considering environmental issues. This has contributed considerably to the pollution of the environment. This paper introduces a framework in which to develop a master plan for industrial solid waste management. There are usually different criteria for evaluating the existing solid waste pollution loads and how effective the management schemes are. A multiple criteria decision making technique, namely Analytical Hierarchy Process, is used for ranking the industrial units based on their share in solid waste related environmental pollution and determining the share of each unit in total solid waste pollution load. In this framework, a comprehensive set of direct, indirect, and supporting projects are proposed for solid waste pollution control. The proposed framework is applied for industrial solid waste management in the province of Khuzestan in Iran and a databank including GIS based maps of the study area is also developed. The results have shown that the industries located near the capital city of the province, Ahwaz, produce more than 32 percent of the total solid waste pollution load of the province. Application of the methodology also has shown that it can be effectively used for development of the master plan and management of industrial solid wastes

  15. Independent technical review of Savannah River Site Defense Waste Processing Facility technical issues

    1992-07-01

    The Savannah River Site (SRS) Defense Waste Processing Facility (DWPF) will vitrify high-level radioactive waste that is presently stored as liquid, salt-cake, and sludge in 51 waste-storage tanks. Construction of the DWPF began in 1984, and the Westinghouse Savannah Company (WSRC) considers the plant to be 100% turned over from construction and 91% complete. Cold-chemical runs are scheduled to begin in November 1992, and hot start up is projected for June 1994. It is estimated that the plant lifetime must exceed 15 years to complete the vitrification of the current, high-level tank waste. In a memo to the Assistant Secretary for Defense Programs (DP-1), the Assistant Secretary for Environmental Restoration and Waste management (EM-1) established the need for an Independent Technical Review (ITR), or the Red Team, to ''review process technology issues preventing start up of the DWPF.'' This report documents the findings of an Independent Technical Review (ITR) conducted by the Department of Energy (DOE), Office of Environmental Restoration and Waste Management (EM), at the request of the Assistant Secretary for Environmental Restoration and Waste Management, of specified aspects of Defense Waste Process Facility (DWPF) process technology. Information for the assessment was drawn from documents provided to the ITR Team by the Westinghouse Savannah River Company (WSRC), and presentations, discussions, interviews, and tours held at the Savannah River Site (SRS) during the weeks of February and March 9, 1992

  16. Federal legislative and regulatory incentives and disincentives for industrial waste reduction

    Cordes, R.; Nixon, J.

    1991-10-01

    The Office of Industrial Technologies (OIT) within the US DOE has recently initiated the Industrial Waste Reduction Program, which is designed to reduce industrial energy use and pollution by reducing the amount of waste materials generated. The Program's primary focus is to develop and commercialize waste reduction technologies and practices in conjunction with industrial partners. OIT recognizes that adoption of these technologies is often inhibited by an assortment of institutional barriers that are unrelated to technical or economic performance. Therefore, OIT is examining selected barriers to industrial waste reduction to help identify and remove impediments to wider technology implementation. This report examines the incentives and disincentives to industrial waste reduction that are provided in an assortment of legislation and regulations. The intent is to shed light on how our environmental laws affect industry's implementation of waste reduction, what particular problems exist with current legislation/regulations, and what general options are available for correcting any deficiencies. Our study was confined strictly to federal legislation and regulations. During the course of the study, (March and May 1991), we examined 16 pieces of existing legislation and their attendant regulations plus 22 pieces of proposed legislation. In addition, the authors consulted representatives from industry and from the government agencies administering or sponsoring the legislation. The Resource Conservation and Recovery Act (RCRA) is by far the most comprehensive and dominant piece of legislation affecting solid waste disposal. This is because RCRA, which governs, the management of both nonhazardous and hazardous waste, places the most restrictive requirements on industry. Other important pieces of legislation that exert a direct influence on waste reduction per se include the Clean Air Act and the Pollution Prevention Act. 90 refs., 12 tabs

  18. Hazardous and Industrial Wastes Management: a Case Study of Khazra Industrial Park, Kerman

    Hossein Jafari Mansoorian

    2013-08-01

    Full Text Available Background & Aims of the Study: Increasing hazardous industrial wastes and lack of necessary regulations for management of them have led to serious problems in some parts of Iran. The aim of this study was to evaluate the situation of collection, transportation, recycling, and disposal of hazardous industrial wastes in the Khazra Industrial Park of Kerman, Iran. Materials & Methods: This study was a descriptive cross-sectional study that was done using questionnaires and local visits during year 2009. In this questionnaire, some information about the industrial wastes, production, storage on site , collection, transformation, sorting, recycling, and disposal were recorded. Results:   In the Khazra Industrial Park, 71,600 kg/day of different industrial waste is produced. The biggest proportion of waste includes metals, and construction and demolition waste which are about 16,500 tons a year. The smallest proportion is non-iron metal waste, which is produced at a rate of 8 tons per year. 88.7 percent of the active industries at the Khazra Industrial Park produce solid industrial waste. Most of the industrial units do not use a united and coordinated system for storing waste and have no specific place for temporary storage inside the industrial park. The majority of industrial waste collection, which is about 59.8%, is done by private contractors. The industrial units transfer their waste separately, and just 9 industrial units recycle their waste. Disposal of these wastes is mainly done by selling to trading agencies. Each day, 3 tons of hazardous industrial waste is produced in this park. The highest production belongs to the oil factory (Keyhan Motor. Conclusions: According to the results, the Khazra Industrial Park needs a unified system for storing, transporting and collecting the sorted waste, and it also needs to have a transportation station with basic facilities. The wastes of most industrial units at the Khazra Industrial Park have the

    Full Text Available Aim. Disposal of industrial waste to improve the environmental safety by means of recycling and reusing in the manufacture of building materials.Materials and methods. We made a selection of new optimum compositions of fiber-concretes using industrial carbon black from heat generating productions, glass fibers, plasticizers, activated mixing water produced using an ultrasonic unit.Results. New fiber-reinforced concrete compositions were developed using carbon black as an additive. As a result of the processing of the experimental data, it has been revealed that introduction of carbon black as an additive contributed to the increase of the strength characteristics of nearly all fiber-reinforced concrete compositions. It has been found that microparticles of carbon black accumulate the products of hydration of portlandcement-hydrosilicate calcium on the surface and contribute to the formation of a solid microarming concrete structure.Conclusions. The use of industrial carbon black in fibrous concrete mixture using restructured water improves its rheological properties, reduces its segregation and improves the homogeneity of the concrete. Recycling and re-using carbon black in the production of building materials will improve the environmental ecology.

  1. Structure of technical systems: interpersonal networks and performance in nuclear waste and photovoltaic research

    Shrum, W.M. Jr.

    1982-01-01

    The organization of scientific technology in modern, industrialized societies is examined by comparing two large-scale, multi-organizational, mission-oriented research networks. Using national data from personal interviews with 297 scientists, engineers, research managers, and policy makers from 97 organizations involved in nuclear waste management and solar-photovoltaic development, this study develops and tests hypotheses on the relationships among governmental, academic, private, and public interest sectors and the kinds of social linkages which are associated with technical performance. The principal finding is that in photovoltaic research, contacts with the research community are associated with high levels of performance, while for nuclear waste researchers, they are not. Instead, linkages to the governmental sector predict performance in nuclear waste research. This difference is explained by the governmental domination of the nuclear-waste system and the lack of private-sector involvement

  3. Schlumberger demonstrates technical leadership to industry

    Anon

    2001-12-01

    The PowerDrive 900 system with a Reed Hycalog drill bit is described. The system is used by Schlumberger in offshore Newfoundland exploration drilling, and is said to have radically reduced the amount of time it takes to drill wells. It is heralded as having allowed Schlumberger to revolutionize the drilling of extended reach wells during 2001. The nine-inch diameter PowerDrive tool is new on the market. It was used on Canada's east coast for the first time in January 2001 on the Hibernia B16-23 wells. Although the original expectation was that the system would improve the removal of drill cuttings from the well, engineers found an even more significant benefit, i. e. well sections are drilled up to 47 per cent faster than with a conventional drilling tool. The new tool is said to be uniquely suited to work above the hard, abrasive Catalina sandstones on Newfoundland's offshore, hence it is very likely to become an important tool for Canada's east coast oil and gas industry. Schlumberger has invested over half a million dollars in developing a service and maintenance centre at its oilfield facility in Mount Pearl, Newfoundland. The PowerDrive 900 is also being used in exploration drilling offshore Nova Scotia. Another Schlumberger innovation, the Modular Formation Dynamic Tester (MDT) is also highlighted as a tool for effectively evaluating reservoirs and acquiring early formation fluids. MDT has been widely utilized in Atlantic Canada's offshore environment recently to map reservoir block pressures. collect representative fluids, and to study well productivity. By using the MDT's optical fluid analyzer Schlumberger was also able to provide a solution for distinguishing formation oil from oil based mud filtrate by measuring the oil-based mud contamination after a few minutes of pumping. 2 photos.

  4. Microbiological and technical aspects of anaerobic waste water purification

    Aivasidis, A.

    1994-01-01

    Anaerobic waste water purification is likely to be another example of how innovations can result from the joint use of biological and technical concepts. No matter how far the optimization of oxygen input with aerobic waste water purification advances it will still be the less a real competitor for anaerobic techniques the more polluted the waste water is. The principle of carrier fixation to avoid their washing out, too, has often been observed in nature with sessile microorganisms. With highly polluted water, anaerobic purification does not only work at no expenditure of energy but it can also make excess energy available for use in other processes. Another important argument for anaerobic methods of waste water purification is probably the clearly reduced production of excess sludge. (orig.) [de

    Streffer, Christian; Kamp, Georg; Kröger, Wolfgang; Rehbinder, Eckard; Renn, Ortwin; Röhlig, Klaus-Jürgen

    2012-01-01

    Waste caused by the use of radioactive material in research, medicine and technologies, above all high level waste from nuclear power plants, must be disposed of safely. However, the strategies discussed for the disposal of radioactive waste as well as proposals for choosing a proper site for final waste disposal are strongly debated. An appropriate disposal must satisfy complex technical requirements and must meet stringent conditions to appropriately protect man and nature from risks of radioactivity over very long periods. Ethical, legal and social conditions must be considered as well. An interdisciplinary team of experts from relevant fields compiled the current status and developed criteria as well as strategies which meet the requirements of safety and security for present and future generations. The study also provides specific recommendations that will improve and optimize the chances for the selection of a repository site implementing the participation of stakeholders including the general public an...

  6. Influence of industrial solid waste addition on properties of soil-cement bricks

    F. B. Siqueira

    Full Text Available Abstract The reuse of pollutant solid wastes produced in distinct industrial activities (avian eggshell waste and welding flux slag waste as a source of alternative raw material for producing soil-cement bricks for civil construction was investigated. Soil-cement bricks containing up to 30 wt% of industrial solid waste were uniaxially pressed and cured for 28 days. Special emphasis is given on the influence of solid waste addition on the technical properties (as such volumetric shrinkage, water absorption, bulk density, durability, and compressive strength, microstructure and mineral phases of soil-cement bricks. Microstructural evolution was evaluated via confocal microscopy. The experimental results showed that the solid wastes behave as charge material and influenced both technical properties and microstructure of the soil-cement bricks. It was found that up to 15 wt% of welding flux slag waste and up to 30 wt% of avian eggshell waste could be added into the soil-cement bricks for use as building material.

  8. Nordic study on reactor waste. Technical part 1 and 2

    1981-08-01

    An important part of the Nordic studies on system- and safety analysis of the management of low and medium level radioactive waste from nuclear power plants, is the safety analysis of a Reference System. This reference system was established within the study and is described in this Technical Part 1. The reference system covers waste management Schemes that are potential possibilities in either one of the four participating Nordic countries. The reference system is based on: a power reactor system consisting of 6 BWR's of 500 MWe each, operated simultaneously over the same 30 year period, and deep bed granular ion exchange resin wastes from the Reactor Water Clean-Up System (RWCS and powdered ion exchange resin from the Spent Fuel Pool Cleanup System (SFPCS)). Both waste types are supposed to be solidified by mixing with cement and bitumen. Two basic types of containers are considered. Standard 200 liter steel drums and specially made cubicreinforced concrete moulds with a net volume of 1 m 3 . The Nordic study assumes temporary storage of the solidified waste for a maximum of 50 years before the waste is transferred to the disposal site. Transportation of the waste from the storage facilitiy to the disposal site will be by road or sea. Three different disposal facilities are considered: Shallow land burial, near surface concrete bunker, and rock cavern with about 30 m granite cover. (EG)

  9. Technical responsibilities in low-level waste disposal

    Murray, R.L.; Walker, C.K.

    1989-01-01

    North Carolina will be the host state for a low-level radioactive waste (LLRW) disposal facility serving the Southeast Compact for 20 yr beginning in 1993. Primary responsibility for the project rests with the North Carolina Low-Level Radioactive Waste Management Authority, a citizen board. The North Carolina project embodies a unique combination of factors that places the authority in a position to exercise technical leadership in the LLRW disposal field. First, the Southeast Compact is the largest in the United States in terms of area, population, and waste generation. second, it is in a humid rather than an arid region. Third, the citizens of the state are intensely interested in preserving life style, environment, and attractiveness of the region to tourists and are especially sensitive to the presence of waste facilities of any kind. Finally, disposal rules set by the Radiation Protection Commission and enforced by the Radiation Protection Section are stricter than the U.S. Nuclear Regulatory Commission's 10CFR61. These four factors support the authority's belief that development of the facility cannot be based solely on engineering and economics, but that social factors, including perceptions of human risk, concerns for the environment, and opinions about the desirability of hosting a facility, should be integral to the project. This philosophy guides the project's many technical aspects, including site selection, site characterization, technology selection and facility design, performance assessment modeling, and waste reduction policies. Each aspect presents its own unique problems

  14. Geologic disposal of radioactive waste: Ethical and technical issues

    Pigford, T.H.

    1999-01-01

    Ethical goals that future people should be protected and should not have to protect themselves from our radioactive waste are claimed by geologic repository projects. The best test of sufficient protection is to show that the calculated individual doses to future farming families are well below a regulatory limit. That limit should be no greater than what is now adopted to protect the public from operating licensed facilities. Present US calculations show doses, at times well beyond 10,000 years, that exceed current accepted limits by at least three orders of magnitude. Notwithstanding, there is a good chance that the goals can still be achieved by careful technical design of the geologic confinement system. But many in the US now propose ways that would allow greater individual exposures from radionuclides that eventually leak from a geologic repository. Examples include: (a) the 10,000-year cutoff proposed by industry, the US Congress, EPA, and DOE, thus obscuring the later times when higher doses are certain to result; (b) the vicinity-average dose proposed by industry and the US Congress; (c) the probabilistic critical groups proposed by EPRI and by the National Research Council's TYMS committee; (d) proposals to rely on future humans to detect and cleanup excessive amounts of radioactivity that may escape from a repository, and (e) the move to base compliance on calculated doses from well water drawn at considerable distance from Yucca Mountain. Each of these proposals would lead to a far more lenient radiation protection standard than current standards. Each of these proposals is without sufficient scientific basis for its use as a protector of public health. Each of these proposals would violate one or more of the ethical goals. Each is made without adequate discussion and explanation and without explaining how and why it would violate one or more of the ethical goals. What if serious work on alternatives fails to produce conservatively calculated and

  16. Long term industrial management of radioactive wastes in France

    Lavie, J.

    1981-01-01

    All human activities including energy generation entail the wastes. This definitely applies also to nuclear power generation. Currently the nuclear power program is very extensive, and the plans of fuel reprocessing proceed along this line. In consequence, the Government has decided on tackling the problem of industrial radioactive waste management in earnest. For the purpose, the National Radioactive Waste Management Agency (ANDRA) was created in November, 1979, within the French Atomic Energy Commission (CEA). Its main functions are the design, siting and construction of waste disposal centers and their management, the establishment of waste treatment and disposal standards, and the research and development. The following matters are described: the need for comprehensive industrial approach, the concept of industrial management, ANDRA business program, the industrial policy on waste disposal, and ANDRA financing.

    The life cycle assessment (LCA) of a waste management system relies on many internal characteristics such as pollution control systems and recovery efficiencies. It also relies on technical externalities supporting the waste management system in terms of capital goods and energy and material...... for the primary and secondary production of materials, 366 datasets were gathered. The materials in focus were: paper, newsprint, cardboard, corrugated board, glass, aluminium, steel and plastics (HDPE, LDPE, LLDPE, PET, PS, PVC). Only one quarter of these data concerned secondary production, thus underlining...

  18. Management of ''short-lifetime'' radioactive wastes, an industrial reality to safeguard the environment

    Faussat, A.

    1992-01-01

    On the occasion of the inauguration of the Aube waste storage center by A.Billardon, Vice Minister for Energy, the author reviews the management situation in France for short life radioactive wastes. The wastes are first defined and their characteristics explained, and then are discussed the general principles underlying the management of these wastes, which involves finding ways to avoid the dispersal of radioactive products into the environment. The author explains why the French have chosen surface storage, and then goes into the integrated management system developed to optimize the long-term management of short-term wastes on the technical and economic levels. The two storage centers existing in France (the Manche and Aube centers) are then described. The article winds up with a presentation of the system as it has been adapted abroad, and another possible adaptation for use in storing toxic industrial wastes. 2 figs., 3 photos

  1. Radon effective dose from TENORM waste associated with petroleum industries

    Abo-Elmagd, M.; Soliman, H. A.; Daif, M. M.

    2009-01-01

    Technically enhanced naturally occurring radioactive material (TENORM) associated with petroleum industries can be accumulated with elevated quantities and therefore can threat the workers through external and internal exposure. Measurements of radon-related parameters give information about the radioactivity levels in the TENORM waste using the well-established correlation. Also, it is useful to calculate the internal exposure due to radon inhalation in terms of effective radon dose. Among radon-related parameters, areal exhalation rate is the most suitable for characterising land and objects with only upper surface contamination in the case of petroleum waste. The TENORM in this study is collected from waste storage areas located near oil fields at south Sinai governorate (Egypt). The average values of exhalation rates as measured by Lucas cell based on delay count method are 273 ± 144 and 38 ± 8 Bq m -2 h -1 for scale and sludge, respectively. Whereas, two count method gives results with 18 and 20 % lower values for scale and sludge, respectively with good correlation coefficient of 0.999 and 0.852, respectively. Sealed cup fitted with CR-39 gives results compatible with Lucas cell with minor deviation in case of scale due to its thoron content. The results of CR-39 are qualified by taking into consideration the correction for back diffusion effect. The effective radon dose was calculated for different simulated radioactive waste storage areas with different contaminated areas and air ventilation rate. Minimising the contaminated areas and building up efficient ventilation systems can reduce the internal exposure even in the case of RWSA-containing TENORM with elevated radioactivity. (authors)

  5. Physico-chemical basics for production of uranium concentrate from wastes of hydrometallurgical plants and technical waters

    Mirsaidov, I.; Nazarov, K.

    2014-01-01

    Physico-chemical and technological basics for reprocessing of uranium industry wastes of Northern Tajikistan shows that the most perspective site for reprocessing is Chkalovkst tailings wastes. The engineering and geological conditions and content of radionuclides in wastes were investigated. It was determined that considered by radioactivity the wastes are low activity and they can be reprocessed for the purpose of U_3O_8 production. Characteristics of mine and technical waters of uranium industry wastes were studied. Characteristics of mine and technical waters of Kiik-Tal and Istiklol city (former Taboshar) showed the expediency of uranium oxide extraction from them. The reasons for non-additional recovery extraction from dumps of SE “Vostokredmet” by classical methods of uranium leaching are studied. The kinetics of sulfuric leaching of residues from anthropogenic deposit of Map 1-9 (Chkalovsk City) were also investigated. Further investigations are to reveal the flow mechanism process of sulfuric leaching of residues and to enable the selection of a radiation regime for U_3O_8 production. The kinetics of sorption process of uranium extraction from mine and technical waters of uranium industry wastes were studied. High sorption properties of apricot shell compared to other sorbents were revealed. A basic process flow diagram for reprocessing of uranium tailing wastes was developed as well as diagrams for uranium extraction from mine and technical waters from uranium industry wastes. The process consists of the following stages: acidification, sorption, burning, leaching, sedimentation, filtration and drying. The possibility of uranium extraction from natural uranic waters of a complicated salt composition was considered. Investigations revealed that uranium extraction from brines containing chloride ion is possible. A developed uranium extraction scheme from Sasik-Kul lake’s brine consists of the following main stages: evaporation, leaching, chloride

    Fang, Hao; Xia, Jianjun; Zhu, Kan; Su, Yingbo; Jiang, Yi

    2013-01-01

    Large quantities of low grade waste heat are discharged into the environment, mostly via water evaporation, during industrial processes. Putting this industrial waste heat to productive use can reduce fossil fuel usage as well as CO 2 emissions and water dissipation. The purpose of this paper is to propose a holistic approach to the integrated and efficient utilization of low-grade industrial waste heat. Recovering industrial waste heat for use in district heating (DH) can increase the efficiency of the industrial sector and the DH system, in a cost-efficient way defined by the index of investment vs. carbon reduction (ICR). Furthermore, low temperature DH network greatly benefits the recovery rate of industrial waste heat. Based on data analysis and in-situ investigations, this paper discusses the potential for the implementation of such an approach in northern China, where conventional heat sources for DH are insufficient. The universal design approach to industrial-waste-heat based DH is proposed. Through a demonstration project, this approach is introduced in detail. This study finds three advantages to this approach: (1) improvement of the thermal energy efficiency of industrial factories; (2) more cost-efficient than the traditional heating mode; and (3) CO 2 and pollutant emission reduction as well as water conservation. -- Highlights: •We review situation of industrial waste heat recovery with a global perspective. •We present a way to analyze the potential to utilize industrial waste heat for DH. •Northern China has huge potential for using low-grade industrial waste heat for DH. •A demonstration project is introduced using the universal approach we propose. •It proves huge benefits for factories, heat-supply companies and the society

  7. RELEASE OF DRIED RADIOACTIVE WASTE MATERIALS TECHNICAL BASIS DOCUMENT

    KOZLOWSKI, S.D.

    2007-01-01

    This technical basis document was developed to support RPP-23429, Preliminary Documented Safety Analysis for the Demonstration Bulk Vitrification System (PDSA) and RPP-23479, Preliminary Documented Safety Analysis for the Contact-Handled Transuranic Mixed (CH-TRUM) Waste Facility. The main document describes the risk binning process and the technical basis for assigning risk bins to the representative accidents involving the release of dried radioactive waste materials from the Demonstration Bulk Vitrification System (DBVS) and to the associated represented hazardous conditions. Appendices D through F provide the technical basis for assigning risk bins to the representative dried waste release accident and associated represented hazardous conditions for the Contact-Handled Transuranic Mixed (CH-TRUM) Waste Packaging Unit (WPU). The risk binning process uses an evaluation of the frequency and consequence of a given representative accident or represented hazardous condition to determine the need for safety structures, systems, and components (SSC) and technical safety requirement (TSR)-level controls. A representative accident or a represented hazardous condition is assigned to a risk bin based on the potential radiological and toxicological consequences to the public and the collocated worker. Note that the risk binning process is not applied to facility workers because credible hazardous conditions with the potential for significant facility worker consequences are considered for safety-significant SSCs and/or TSR-level controls regardless of their estimated frequency. The controls for protection of the facility workers are described in RPP-23429 and RPP-23479. Determination of the need for safety-class SSCs was performed in accordance with DOE-STD-3009-94, Preparation Guide for US.

  8. Hospital waste sterilization: a technical and economic comparison between radiation and microwave treatments

    Tata, A.; Beone, F.

    1995-01-01

    Hospital waste (HW) disposal is becoming a problem of increasing importance in almost all industrially advanced countries. In Italy the yearly hospital waste production is about 250,000 tons and only 60,000 are treated by incineration at present time. As by a recent Italian law a meaningful percentage of HW (50 to 60%), corresponding to food residuals, plastic, paper, various organic materials, etc., could be landfilled as municipal refuses if preliminarily submitted to a suitable sterilization treatment. Under this perspective, sterilization/sanitation techniques represent now a technically and commercially viable alternative to HW thermal destruction that, besides more and more socially and politically less accepted. Electron Beam (EB) and Microwave (MW) treatments are two of the most interesting and emerging HW sterilization techniques, and, based on engineering real data, a technical and economic comparison is carried out, focusing vantages and limits of each process.

  9. Technical issues in the geologic disposal of radioactive wastes

    Weart, W.D.

    1980-01-01

    The status of technical understanding regarding radioactive waste repositories in geologic media is improving at a rapid rate. Within a few years the knowledge regarding non-salt repositories will be on a par with that which now exists for salt. To date there is no technical reason to doubt that geologic repositories in several different geologic media can be safely implemented to provide long-term isolation of radioactive wastes. Indeed, for bedded salt, there is now sufficient knowledge to allow all the identified phenomena to be bounded with satisfactory resultant consequences. It is possible to now proceed with technical confidence in an orderly development of a bedded-salt repository at a satisfactory site. This development would call for in-situ experiments, at the earliest possible stage, to confirm or validate the predictions made for the site. These in-situ experiments will be necessary for each repository in a different rock type. If, for non-technical reasons, repository development is delayed, field test facilities should be located as soon as possible in geologic settings typical of proposed repositories. Extensive testing to resolve generic issues will allow subsequent development of repositories to proceed more rapidly with only minimal in-situ testing required to resolve site-specific concerns

    Full Text Available Waste heat recovery in Croatian industry is of the highest significance regarding the national efforts towards energy efficiency improvements and climate protection. By recuperation of heat which would otherwise be wasted, the quantity of fossil fuels used for production of useful energy could be lowered thereby reducing the fuel costs and increasing the competitiveness of examined Croatian industries. Another effect of increased energy efficiency of industrial processes and plants is reduction of greenhouse gases i.e. the second important national goal required by the European Union (EU and United Nations Framework Convention on Climate Change (UNFCCC. Paper investigates and analyses the waste heat potential in Croatian industrial sector. Firstly, relevant industrial sectors with significant amount of waste heat are determined. Furthermore, significant companies in these sectors are selected with respect to main process characteristics, operation mode and estimated waste heat potential. Data collection of waste heat parameters (temperature, mass flow and composition is conducted. Current technologies used for waste heat utilization from different waste heat sources are pointed out. Considered facilities are compared with regard to amount of flue gas heat. Mechanisms for more efficient and more economic utilization of waste heat are proposed. [Acknoledgment.

    Thiriet, L.; Sauteron, J.; Oger, C.

    1968-01-01

    The paper briefly reviews the various techniques used in processing the radioactive wastes which unavoidably result from the generation of electric power from nuclear sources. The paper goes on to define the relative importance, in nuclear fuel cycles, of the problem raised by these wastes. Emphasis is placed on the economic influence of management policies on the cost of power generation, and hence on the relative position of nuclear energy. A substantial percentage of these wastes can be economically utilized. Attention is drawn to the major technical and economic features of the industry which will come into being as a result of this utilization. The major uses anticipated are discussed: radiation sources, heat sources, auxiliary power generation. The paper concludes that satisfactory solutions have already been found to these problems, and describes possible improvements. (author) [fr

    1993-07-01

    The radioactive waste storage remains, in most of the industrialized concerned countries, one extremely debated question. This problem may, if an acceptable socially answer is not found, to create obstacles to the whole nuclear path. This study aim was to analyze the controversy in an historical outlook. The large technological plans have always economical, political, sociological, , psychological and so on aspects, that the experts may be inclined to neglect. ''Escape of radioactivity is unlikely, as long as surveillance of the waste is maintained, that is, as long as someone is present to check for leaks or corrosion or malfunctioning of and to take action, if any of these occur. 444 refs., 32 figs

    The Final Waste Forms (FWF) Technical Area Status Report (TASR) Working Group, the Vitrification Working Group (WG), and the Performance Standards Working Group were established as subgroups to the FWF Technical Support Group (TSG). The FWF TASR WG is comprised of technical representatives from most of the major DOE sites, the Nuclear Regulatory Commission (NRC), the EPA Office of Solid Waste, and the EPA's Risk Reduction Engineering Laboratory (RREL). The primary activity of the FWF TASR Working Group was to investigate and report on the current status of FWFs for LLNM in this TASR. The FWF TASR Working Group determined the current status of the development of various waste forms described above by reviewing selected articles and technical reports, summarizing data, and establishing an initial set of FWF characteristics to be used in evaluating candidate FWFS; these characteristics are summarized in Section 2. After an initial review of available information, the FWF TASR Working Group chose to study the following groups of final waste forms: hydraulic cement, sulfur polymer cement, glass, ceramic, and organic binders. The organic binders included polyethylene, bitumen, vinyl ester styrene, epoxy, and urea formaldehyde. Section 3 provides a description of each final waste form. Based on the literature review, the gaps and deficiencies in information were summarized, and conclusions and recommendations were established. The information and data presented in this TASR are intended to assist the FWF Production and Assessment TSG in evaluating the Technical Task Plans (TTPs) submitted to DOE EM-50, and thus provide DOE with the necessary information for their FWF decision-making process. This FWF TASR will also assist the DOE and the MWIP in establishing the most acceptable final waste forms for the various LLMW streams stored at DOE facilities

  2. Technical and economical feasibility of the hybrid adsorption compression heat pump concept for industrial applications

    Pal, Michel van der; Wemmers, Anton; Smeding, Simon; Boer, Robert de

    2013-01-01

    Heat pump technologies offer a significant potential for primary energy savings in industrial processes. Thermally driven heat pumps can use waste heat as driving energy source to provide either heating or cooling. A chemi-sorption heat transformer can upgrade a waste heat source to temperatures of 150–200 °C. The specific heat transformer process however requires waste heat temperatures in the range of 120 °C, whereas waste heat sources of lower temperatures are more abundant. Using this lower temperature waste heat, and still reach the desired higher output temperatures can be achieved by the integration of a chemisorption and mechanical compression step in a single hybrid heat pump concept. This concept can offer an increased flexibility in temperatures, both for the waste heat source as for the heat delivery. The technical and economical feasibility of the proposed hybrid heat pump concept is evaluated. The range of operating temperatures of different chemi-sorption working pairs for as heat driven and as hybrid systems are defined, as well as their energy efficiencies. Investment costs for the hybrid systems are derived and payback times are calculated. The range of payback times is from 2 to 9 years and are strongly influenced by the number of operating hours, the electrical COP of the compression stage, and the energy prices

    Manaktala, H.K.; Interrante, C.G.

    1990-12-01

    This report deals with technical information that is considered essential for demonstrating the ability of the high-level radioactive waste package to provide ''substantially complete containment'' of its contents (vitrified waste form or spent light-water reactor fuel) for a period of 300 to 1000 years in a geological repository environment. The discussion is centered around technical considerations of the repository environment, materials and fabrication processes for the waste package components, various degradation modes of the materials of construction of the waste packages, and inspection and monitoring of the waste package during the preclosure and retrievability period, which could begin up to 50 years after initiation of waste emplacement. The emphasis in this report is on metallic materials. However, brief references have been made to other materials such as ceramics, graphite, bonded ceramic-metal systems, and other types of composites. The content of this report was presented to an external peer review panel of nine members at a workshop held at the Center for Nuclear Waste Regulatory Analyses (CNWRA), Southwest Research Institute, San Antonio, Texas, April 2--4, 1990. The recommendations of the peer review panel have been incorporated in this report. There are two companion reports; the second report in the series provides state-of-the-art techniques for uncertainty evaluations. 97 refs., 1 fig

  5. Radioactive waste disposal programme 2008 of the waste-management-compelled bodies. Technical report 08-01

    2008-10-01

    Important steps in the management of radioactive waste have already been implemented in Switzerland and there is now wide experience in carrying out the associated activities. In terms of preparing for deep geological disposal, the necessary scientific and technical work is well advanced and the feasibility of implementing geological repositories that provide the required long-term safety has been successfully demonstrated for all wastes arising in Switzerland. Test feasibility demonstrations have also been approved by the Federal Council. Sufficient knowledge is available to allow the next steps in the selection of repository sites to be performed. The legal framework and organisational measures are also in place. The conceptual part of the Sectoral Plan for deep geological repositories regulates the details of the site selection process to be conducted over the next years. The origin, types and volumes of radioactive waste to be disposed of in Switzerland are known. The reference case assumes operation of the existing nuclear power plants for a period of 50 years and a collection period up to around 2050 for radioactive waste from medicine, industry and research. The types and volumes of radioactive waste that would arise in the case of extension of the operating lifetime of the existing power plants and the collection period for waste from medicine, industry and research by 10 years are included for planning purposes. Also considered are the wastes to be expected in the case of an additional production of 5 GW e for a period of 60 years. The resulting wastes are conditioned, characterised and inventoried on an ongoing basis. Before conditioning of a waste stream begins, the proposed conditioning procedure is evaluated by Nagra in terms of the suitability for disposal of the resulting waste packages. A model inventory of waste that will arise in the future has also been compiled. This provides a reliable basis for planning and implementing geological repositories

    Stijepovic, Mirko Z.; Linke, Patrick

    2011-01-01

    Significant energy efficiency gains in zones with concentrated activity from energy intensive industries can often be achieved by recovering and reusing waste heat between processing plants. We present a systematic approach to target waste heat recovery potentials and design optimal reuse options across plants in industrial zones. The approach first establishes available waste heat qualities and reuse feasibilities considering distances between individual plants. A targeting optimization problem is solved to establish the maximum possible waste heat recovery for the industrial zone. Then, a design optimization problem is solved to identify concrete waste heat recovery options considering economic objectives. The paper describes the approach and illustrates its application with a case study. -- Highlights: → Developed a systematic approach to target waste heat recovery potentials and to design optimal recovery and reuse options across plants in industrial zones. → Five stage approach involving data acquisition, analysis, assessment, targeting and design. → Targeting optimization problem establishes the maximum possible waste heat recovery and reuse limit for the industrial zone. → Design optimization problem provides concrete waste heat recovery and reuse network design options considering economic objectives.

  10. Arsenic in industrial waste water from copper production technological process

    Biljana Jovanović

    2013-12-01

    Full Text Available Investigation of arsenic in industrial waste water is of a great importance for environment. Discharge of untreated waste water from a copper production process results in serious pollution of surface water, which directly affects flora and fauna, as well as humans. There is a need for efficient and environmentally acceptable treament of waste waters containing heavy metals and arsenic. The paper presents an analyisis of the waste water from The Copper Smelter which is discharged into the Bor river. The expected arsenic content in treated waste water after using HDS procedure is also presented.

    Proteases are ubiquitous enzymes that occur in various biological systems ranging from microorganisms to higher organisms. Microbial proteases are largely utilized in various established industrial processes. Despite their numerous industrial applications, they are not efficient in hydrolysis of recalcitrant, protein-rich keratinous wastes which result in environmental pollution and health hazards. This paved the way for the search of keratinolytic microorganisms having the ability to hydrolyze "hard to degrade" keratinous wastes. This new class of proteases is known as "keratinases". Due to their specificity, keratinases have an advantage over normal proteases and have replaced them in many industrial applications, such as nematicidal agents, nitrogenous fertilizer production from keratinous waste, animal feed and biofuel production. Keratinases have also replaced the normal proteases in the leather industry and detergent additive application due to their better performance. They have also been proved efficient in prion protein degradation. Above all, one of the major hurdles of enzyme industrial applications (cost effective production) can be achieved by using keratinous waste biomass, such as chicken feathers and hairs as fermentation substrate. Use of these low cost waste materials serves dual purposes: to reduce the fermentation cost for enzyme production as well as reducing the environmental waste load. The advent of keratinases has given new direction for waste management with industrial applications giving rise to green technology for sustainable development.

    1993-10-01

    In January of 1992 a team was put together to begin the process of assessing the industrial waste needs of the Tennessee Valley. The team consisted of representatives from the various TVA Resource Group organizations. This initial team recommended as a starting point in the process a two-phase market research effort. A second team was then commissioned to conduct the first phase of this market research effort. The first phase of that marketing effort is now complete. This report contains an analysis of the data obtained through interviews of more than 168 individuals representing a similar number of organizations. A total of 37 TVA Resource Group employees were involved in the contact process from various organizations. In addition, the appendices provide summaries of the data used in designing the process and the reports of the Contact Coordinators (who were responsible for a series of visits). As a result of the data analysis, the Review Team makes the following recommendations: 1. Publish this report and distribute to the new management within TVA Resource Group as well as to all those participating as contacts, visitors, and contact coordinators. 2. The Resource Group management team, or management teams within each of the respective organizations within Resource Group, appoint Phase 2 assessement teams for as many of the problem areas listed in Table III as seem appropriate. We further recommend that, where possible, cross-organizational teams be used to examine individual problem areas. 3. Make this report available within Generating and Customer Groups, especially to the Customer Service Centers. 4. Establish a process to continue follow up with each of the contacts made in this assessment.

  14. Methodology for quantitative assessment of technical condition in industrial systems

    Steinbach, C. [Marintek AS (Norway); Soerli, A. [Statoil (Norway)

    1998-12-31

    As part of the Eureka project Ageing Management a methodology has been developed to assess the technical condition of industrial systems. The first part of the presentation argues for the use of technical condition parameters in the context of maintenance strategies. Thereafter the term `technical condition` is defined more thoroughly as it is used within the project. It is claimed that the technical condition of a system - such as a feed water system of a nuclear power plant, or a water injection system on an oil platform - may be determined by aggregating the condition of its smaller components using a hierarchic approach. The hierarchy has to be defined in co-operation with experienced personnel and reflects the impact of degradation of elements on a lower level to nodes higher in the hierarchy. The impact is divided into five categories with respect to safety, environment, availability, costs and man-hours. To determine the technical condition of the bottom elements of the hierarchy, available data is used from both an on-line condition monitoring system and maintenance history. The second part of the presentation introduces the prototype software tool TeCoMan which utilises the theory and applies it to installations of the participating companies. First results and gained experiences with the method and tool are discussed. (orig.)

  16. Optimised anaerobic treatment of house-sorted biodegradable waste and slaughterhouse waste in a high loaded half technical scale digester.

    Resch, C; Grasmug, M; Smeets, W; Braun, R; Kirchmayr, R

    2006-01-01

    Anaerobic co-digestion of organic wastes from households, slaughterhouses and meat processing industries was optimised in a half technical scale plant. The plant was operated for 130 days using two different substrates under organic loading rates of 10 and 12 kgCOD.m(-3).d(-1). Since the substrates were rich in fat and protein components (TKN: 12 g.kg(-1) the treatment was challenging. The process was monitored on-line and in the laboratory. It was demonstrated that an intensive and stable co-digestion of partly hydrolysed organic waste and protein rich slaughterhouse waste can be achieved in the balance of inconsistent pH and buffering NH4-N. In the first experimental period the reduction of the substrate COD was almost complete in an overall stable process (COD reduction >82%). In the second period methane productivity increased, but certain intermediate products accumulated constantly. Process design options for a second digestion phase for advanced degradation were investigated. Potential causes for slow and reduced propionic and valeric acid degradation were assessed. Recommendations for full-scale process implementation can be made from the experimental results reported. The highly loaded and stable codigestion of these substrates may be a good technical and economic treatment alternative.

  17. Solid recovered fuels in the cement industry with special respect to hazardous waste.

    Thomanetz, Erwin

    2012-04-01

    Cements with good technical properties have been produced in Europe since the nineteenth century and are now worldwide standardized high-quality mass products with enormous production numbers. The basic component for cement is the so-called clinker which is produced mainly from raw meal (limestone plus clay plus sands) in a rotary kiln with preheater and progressively with integrated calciner, at temperatures up to 1450 °C. This process requires large amounts of fossil fuels and is CO₂-intensive. But most CO₂ is released by lime decomposition during the burning process. In the 1980s the use of alternative fuels began--firstly in the form of used oil and waste tyres and then increasingly by pre-conditioned materials from commercial waste and from high calorific industrial waste (i.e. solid recovered fuel (SRF))--as well as organic hazardous waste materials such as solvents, pre-conditioned with sawdust. Therefore the cement industry is more and more a competitor in the waste-to-energy market--be it for municipal waste or for hazardous waste, especially concerning waste incineration, but also for other co-incineration plants. There are still no binding EU rules identifying which types of SRF or hazardous waste could be incinerated in cement kilns, but there are some well-made country-specific 'positive lists', for example in Switzerland and Austria. Thus, for proper planning in the cement industry as well as in the waste management field, waste disposal routes should be considered properly, in order to avoid surplus capacities on one side and shortage on the other.

  18. Toxicological evaluation of complex industrial wastes: Implications for exposure assessment

    DeMarini, D.M.; Gallagher, J.E.; Houk, V.S.; Simmons, J.E.

    1989-01-01

    A variety of short-term bioassays to construct a battery of tests that could be used for assessing the biological effects of potentially hazardous complex industrial wastes were evaluated. Ten samples were studied for hepatotoxicity: These samples and an additional five were studied for mutagenicity. Although the data are limited to these samples, the results suggest that the Salmonella assay (either TA98 or TA100) or a prophage-induction assay (both in the presence of S9) in combination with determination of relative liver weight and levels of a set of serum enzymes in rats would provide a battery of tests suitable to characterize complex industrial wastes for mutagenic and hepatotoxic potential. The biological activities exhibited by the wastes were not readily predicted by the chemical profiles of the wastes, emphasizing the importance of characterizing potentially hazardous complex industrial wastes by both chemical and biological means.

  19. Technical resource documents and technical handbooks for hazardous-wastes management

    Schomaker, N.B.; Bliss, T.M.

    1986-07-01

    The Environmental Protection Agency is preparing a series of Technical Resource Documents (TRD's) and Technical Handbooks to provide best engineering control technology to meet the needs of the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response Compensation and Liability Act (CERCLA) respectively. These documents and handbooks are basically compilation of research efforts of the Land Pollution Control Division (LPCD) to date. The specific areas of research being conducted under the RCRA land disposal program relate to laboratory, pilot and field validation studies in cover systems, waste leaching and solidification, liner systems and disposal facility evaluation. The technical handbooks provide the EPA Program Offices and Regions, as well as the states and other interested parties, with the latest information relevant to remedial actions.

  20. Analytical methods for waste minimisation in the convenience food industry.

    Darlington, R; Staikos, T; Rahimifard, S

    2009-04-01

    Waste creation in some sectors of the food industry is substantial, and while much of the used material is non-hazardous and biodegradable, it is often poorly dealt with and simply sent to landfill mixed with other types of waste. In this context, overproduction wastes were found in a number of cases to account for 20-40% of the material wastes generated by convenience food manufacturers (such as ready-meals and sandwiches), often simply just to meet the challenging demands placed on the manufacturer due to the short order reaction time provided by the supermarkets. Identifying specific classes of waste helps to minimise their creation, through consideration of what the materials constitute and why they were generated. This paper aims to provide means by which food industry wastes can be identified, and demonstrate these mechanisms through a practical example. The research reported in this paper investigated the various categories of waste and generated three analytical methods for the support of waste minimisation activities by food manufacturers. The waste classifications and analyses are intended to complement existing waste minimisation approaches and are described through consideration of a case study convenience food manufacturer that realised significant financial savings through waste measurement, analysis and reduction.

  5. Solid industrial wastes and their management in Asegra (Granada, Spain)

    Casares, M.L.; Ulierte, N.; Mataran, A.; Ramos, A.; Zamorano, M.

    2005-01-01

    ASEGRA is an industrial area in Granada (Spain) with important waste management problems. In order to properly manage and control waste production in industry, one must know the quantity, type, and composition of industrial wastes, as well as the management practices of the companies involved. In our study, questionnaires were used to collect data regarding methods of waste management used in 170 of the 230 businesses in the area of study. The majority of these companies in ASEGRA are small or medium-size, and belong to the service sector, transport, and distribution. This was naturally a conditioning factor in both the type and management of the wastes generated. It was observed that paper and cardboard, plastic, wood, and metals were the most common types of waste, mainly generated from packaging (49% of the total volume), as well as material used in containers and for wrapping products. Serious problems were observed in the management of these wastes. In most cases they were disposed of by dumping, and very rarely did businesses resort to reuse, recycling or valorization. Smaller companies encountered greater difficulties when it came to effective waste management. The most frequent solution for the disposal of wastes in the area was dumping

  6. Position paper on irradiated fuel and waste management. The Achille's heel of the nuclear industry?

    2014-07-15

    The management and final disposal of irradiated fuel and nuclear waste is often presented by the media and perceived by the public as being an unsolved problem that restricts the future of nuclear energy. However, the nuclear industry focused on this problem very early on and has developed proven technical solutions. Nuclear energy will continue developing worldwide, in spite of the Fukushima accident. Even in those European countries that have decided to phase-out nuclear energy there is a legacy of nuclear waste that must be dealt with. The scientific and technical expertise needed for waste management already exists. Management decisions must be taken. Now is the time for political courage. (orig.)

    1996-01-01

    In conjunction with the affected States as part of their interactions required by the Federal Facilities Compliance Act, the Department of Energy has been developing a process for a disposal configuration for its mixed low-level waste (MLLW). This effort, spanning more than two years, has reduced the potential disposal sites from 49 to 15. The remaining 15 sites have been subjected to a performance evaluation to determine their strengths and weaknesses for disposal of MLLW. The process has included institutional and policy factors as well as strictly technical analyses, and technical analyses must be supported by technical analyses, and technical analyses must be performed within a framework which includes some institutional considerations, with the institutional considerations selected for inclusion largely a matter of policy. While the disposal configuration process is yet to be completed, the experience to date offers a viable approach for solving some of these issues. Additionally, several factors remain to be addressed before an MLLW disposal configuration can be developed

  10. Exploitation of Food Industry Waste for High-Value Products.

    Ravindran, Rajeev; Jaiswal, Amit K

    2016-01-01

    A growing global population leads to an increasing demand for food production and the processing industry associated with it and consequently the generation of large amounts of food waste. This problem is intensified due to slow progress in the development of effective waste management strategies and measures for the proper treatment and disposal of waste. Food waste is a reservoir of complex carbohydrates, proteins, lipids, and nutraceuticals and can form the raw materials for commercially important metabolites. The current legislation on food waste treatment prioritises the prevention of waste generation and least emphasises disposal. Recent valorisation studies for food supply chain waste opens avenues to the production of biofuels, enzymes, bioactive compounds, biodegradable plastics, and nanoparticles among many other molecules.

  11. Determination of Heavy Metal Levels in Various Industrial Waste Waters

    Mustafa Şahin Dündar

    2012-06-01

    Full Text Available Important part of the environmetal pollution consists of waste water and water pollution. The water polluted by anthropogenical, industrial, and agricultural originated sources are defined as waste waters which are the main pollution sources for reservoirs, rivers, lakes, and seas. In this work, waste waters of leather, textile, automotive side, and metal plating industries were used to determine the levels of Cu, Zn, Cr, Pb and Ni by using Flame Atomic Absorption Spectrometer. As a result, highest mean levels of copper in supernatants of plating and textile industries were observed as 377,18 ng ml-1, respectively 103 ng ml-1 lead and 963,6 ng ml-1 nickel in plating industry, 1068,2 ng ml-1 zinc and 14557,1 ng ml-1 chromium in plating and leather industries were determined.

  13. Separate collection of plastic waste, better than technical sorting from municipal solid waste?

    Feil, Alexander; Pretz, Thomas; Jansen, Michael; Thoden van Velzen, Eggo U

    2017-02-01

    The politically preferred solution to fulfil legal recycling demands is often implementing separate collection systems. However, experience shows their limitations, particularly in urban centres with a high population density. In response to the European Union landfill directive, mechanical biological waste treatment plants have been installed all over Europe. This technology makes it possible to retrieve plastic waste from municipal solid waste. Operators of mechanical biological waste treatment plants, both in Germany and the Netherlands, have started to change their mechanical separation processes to additionally produce plastic pre-concentrates. Results from mechanical biological waste treatment and separate collection of post-consumer packaging waste will be presented and compared. They prove that both the yield and the quality of plastic waste provided as feedstock for the production of secondary plastic raw material are largely comparable. An economic assessment shows which conditions for a technical sorting plant are economically attractive in comparison to separate collection systems. It is, however, unlikely that plastic recycling will ever reach cost neutrality.

  14. Technological Proposals for Recycling Industrial Wastes for Environmental Applications

    Isabel Romero-Hermida

    2014-08-01

    Full Text Available A two-fold objective is proposed for this research: removing hazardous and unpleasant wastes and mitigating the emissions of green house gasses in the atmosphere. Thus, the first aim of this work is to identify, characterize and recycle industrial wastes with high contents of calcium or sodium. This involves synthesizing materials with the ability for CO2 sequestration as preliminary work for designing industrial processes, which involve a reduction of CO2 emissions. In this regard, phosphogypsum from the fertilizer industry and liquid wastes from the green olive and bauxite industries have been considered as precursors. Following a very simple procedure, Ca-bearing phosphogypsum wastes are mixed with Na-bearing liquid wastes in order to obtain a harmless liquid phase and an active solid phase, which may act as a carbon sequestration agent. In this way, wastes, which are unable to fix CO2 by themselves, can be successfully turned into effective CO2 sinks. The CO2 sequestration efficiency and the CO2 fixation power of the procedure based on these wastes are assessed.

DNA from liver, lung, and bladder of rats exposed to some of the wastes was analyzed by the 32P-postlabeling technique for the presence of DNA adducts. A waste that produced mutagenic urine produced a DNA adduct in bladder DNA. The implications of this approach for assessment of exposure to complex hazardous waste mixtures are discussed.

    Available for the time being in the Russian Federation, a system of management of institutional and industrial radioactive waste (e.g. radioactive waste from industry, medicine, scientific organizations and other, which are not related to the nuclear fuel cycle or defense) provides for its collection, transportation, storage, treatment, immobilization and disposal by a network of special enterprises. Russia has 16 such enterprises. Moscow Scientific and Industrial Association Radon deals with the problems of radioactive waste from Central European part of Russia, which includes Moscow, Moscow Region and also Tverskaya, Yaroslavskaya, Vladimirskaya, Kostromskaya, Kaluzhskaya, Bryanskaya, Smolenskaya, Tulskaya, Ryazanskaya regions. The population of the central part of Russia constitutes about 40 million people. At the same time about 80% of the radioactive waste, which is collected for treatment and disposal from the territory of Russia, is included in this region. The average volume of the waste to be treated at SIA Radon is 3,000 m 3 per year for solid waste and 350 m 3 per year for liquid waste. Total radioactivity of processed waste is up to 4 PBq per year

    Overwhelming waste-recycling should be considered more as a psychological than as a technological method to deal with wastes. The best waste disposal systems should actually grant mass or energy recovery from technical, economic and ecological point-of-views. Highest results seem to be granted by waste-to-energy technologies since energy content is the best preserved property after using materials

  20. Technical support for the Ukrainian State Committee for Nuclear Radiation Safety on specific waste issues

    Little, C.A.

    1995-01-01

    The government of Ukraine, a now-independent former member of the Soviet Union, has asked the United States to assist its State Committee for Nuclear and Radiation Safety (SCNRS) in improving its regulatory control in technical fields for which it has responsibility. The US Nuclear Regulatory Commission (NRC) is providing this assistance in several areas, including management of radioactive waste and spent fuel. Radioactive wastes resulting from nuclear power plant operation, maintenance, and decommissioning must be stored and ultimately disposed of appropriately. In addition, radioactive residue from radioisotopes used in various industrial and medical applications must be managed. The objective of this program is to provide the Ukrainian SCNRS with the information it needs to establish regulatory control over uranium mining and milling activities in the Zheltye Vody (Yellow Waters) area and radioactive waste disposal in the Pripyat (Chernobyl) area among others. The author of this report, head of the Environmental Technology Section, Health Sciences Research Division of Oak Ridge National Laboratory, accompanied NRC staff to Ukraine to meet with SCNRS staff and visit sites in question. The report highlights problems at the sites visited and recommends license conditions that SCNRS can require to enhance safety of handling mining and milling wastes. The author's responsibility was specifically for the visit to Zheltye Vody and the mining and milling waste sites associated with that facility. An itinerary for the Zheltye Vody portion of the trip is included as Appendix A

  1. Analyzing solid waste management practices for the hotel industry

    S.T. Pham Phu

    2018-01-01

    Full Text Available The current study aims to analyze waste characteristics and management practices of the hotel industry in Hoi An, a tourism city in the center of Vietnam. Solid wastes from 120 hotels were sampled, the face-to-face interviews were conducted, and statistical methods were carried out to analyze the data. The results showed that the mean of waste generation rate of the hotels was 2.28 kg/guest/day and strongly correlated to internal influencing factors such as the capacity, the price of the room, garden, and level of restaurant. The differences in waste generation rate of the hotels were proved to be statistically significant. The higher the scale of hotels, the higher the waste generation rate. Moreover, the waste composition of the hotels was identified by 58.5% for biodegradable waste, 25.8% for recyclables and 15.7% for others. The relative differences in the waste composition of the hotels by climate, the features of hotels, and the types of the guest were explained. Whereby, the higher size of the hotels, the higher percentage of biodegradable and less proportion of recyclable waste. Also, this study revealed that the implementation status of waste management practices of the hoteliers initially reaped quite positive achievements with 76% for sorting, 39% for recycling, 29% for reduction, and 0.8% for composting. The rate of waste management practices was proportional to the scale of the hotel. This study provided information on waste management practice of hotel industry and contributed to the overall assessment of municipal solid waste management practices of Hoi An city.

  2. An industrial ecology approach to municipal solid waste ...

    Municipal solid waste (MSW) can be viewed as a feedstock for industrial ecology inspired conversions of wastes to valuable products and energy. The industrial ecology principle of symbiotic processes using waste streams for creating value-added products is applied to MSW, with examples suggested for various residual streams. A methodology is presented to consider individual waste-to-energy or waste-to-product system synergies, evaluating the economic and environmental issues associated with each system.

  4. Nordic study on reactor waste. Technical part 3

    1981-08-01

    The ground disposal alternatives examined in the Nordic study are based on establishment of relevant product specifications which can be adapted to the safety analysis of the entire waste handling sequence. Such product specifications would in turn influence the choice of incorporation techniques and may enable an optimization of the process. In order to interprete the small-scale laboratory tests with respect to long-term performance of full-scale products there were accomplished: - qualitative evaluations of the relevance of product properties for normal and abnormal events during storage, transport and disposal; - attempts to quantify the relevance of different properties, i.e. their influence on radiation doses from different stages of well specified waste management system; - assessments of available laboratory tests and of correlations between results from such tests and the long-term performance of full-scale technical products; - studies of reaction mechanisms and parameters that can affect the long-term performance of disposed products; - laboratory incorporation experiments to study impacts of process variables on the fixation of ion exchange wastes in cement and bitumen; - full-scale tests to study product performance under simulated accident conditions.

    Plecas, I.; Pavlovic, R.; Pavlovic, S.

    2002-01-01

    Yugoslavia is a country without any Nuclear Power Plant on its territory. In the last forty years, in Nuclear Sciences Institute 'Vinca', as a result of the two reactors operation, named RA and RB, and as a result of the radionuclides application in medicine, industry and agriculture, radioactive waste materials of different levels of specific activity were generated. As a temporary solution, radioactive waste materials are stored in two interim storage facilities. Radwaste that were immobilized in the inactive matrices are to be placed into the concrete containers, for the further manipulation and disposal. The present paper reports the results on preliminary removal of sludge from the bottom of the spent fuel storage pool in RA reactor, mechanical filtration of the pool water and sludge conditioning and storage.

  6. Technical conservatism in the design and analysis of a nuclear-waste repository in basalt

    Jones, K.A.

    1982-01-01

    The US Department of Energy's National Waste Terminal Storage Program has adopted a policy of technical conservatism to guide the design and analysis of geologic disposal systems for commercial high-level radioactive waste. Technical conservatism serves as the programmatic philosophy for managing uncertainty in the performance of the disposal system. The implementation of technical conservatism as applied to a nuclear waste repository in basalt is discussed. Preliminary assessments of the performance of the waste package, repository, and site subsystems are compared to key proposed regulatory criteria. The comparison shows that there are substantial safety margins in the predicted performance of the nuclear waste repository in basalt

  7. Technical aspects of coal use in the Japanese steel industry

    Iguchi, T.

    1991-01-01

    Japan's crude steel production exceeded 100 million tons for the first time in fiscal 1972 and reached a peak of 120 million tons in fiscal 1973, as shown in this paper. The Japanese steel industry then switched from quantity to quality in line with production and market trends in the world. In fiscal 1987, all steelmakers announced future plans for reductions in steel production facilities on the assumption that Japan's crude steel production would hover around 90 million tons in response to the change in the country's production structure. Although steel production has held strong with the expansion in domestic steel demand triggered by the government's economic policy and the production plans that have eventually put their original production plans into practice. In its energy-saving activities prompted by 2 oil rises, the Japanese steel industry has dramatically improved its energy costs through energy conservation, waste heat recovery and process step consolidation, as represented by the reductions in blast furnace fuel rate and coke-oven heat consumption. During this period, the Japanese steel industry has won independence from oil and increased dependence on coal. This paper describes coal utilization technologies in coke ovens and blast furnaces, 2 major coal consuming processes in the steel industry. The environmental problems associated with the use of coal are discussed as well

  8. Technical development of graphite waste treatment in NUPEC

    Saishu, S.; Inoue, T.

    2001-01-01

    In Japan, Tokai Power Station, which is a Gas Cooled Reactor and uses graphite as moderator, ceased operation at the end of March in 1998 and it is planned to transfer to decommissioning stage. In this decommissioning stage it is very important to be able to treat and dispose the graphite waste in order to carry out the decommissioning safely and economically. NUPEC has been developing the graphite treatment and disposal technology since 1997 and we introduce the outline of the technical development. For the technology on high density packing into disposal container, the high density packing method and the assessment method on nuclide leaching characteristics were developed, and the cementing test for graphite powder by using Tokai spare graphite was performed and the hydrophobic characteristics between graphite and cement was grasped and the accelerator candidature for affinity was selected. From the view point of economical treatment, the incinerating technology was selected as candidature, and the methods for incinerating graphite and treating off gas are developed. The method of collecting C-14 in off gas was selected for reducing the off gas radiation level. The applicability of actual graphite treatment technology was considered from the view point of safety, economics and preparation of technical standard; the technical theme appeared, the developing planning items were established, and the detailed and actual scale tests will be carried out according to the planning.

  14. Sustainable network of independent technical expertise for radioactive waste disposal

    Serres, Christophe; Rocher, Muriel; Lemy, Frank; Havlova, Vaclava; Mrskova, Adela; Heriard Dubreuil, Gilles

    2014-01-01

    Full text of publication follows: SITEX is a 24-month FP7 project led by IRSN and bringing together 15 organisations representing technical safety organisations (TSO) and safety authorities, as well as civil society outreach specialists involved in the 'regulatory' review process of geological disposal of radioactive waste. SITEX aims at establishing the conditions required for developing a sustainable network of experts from various horizons (authorities, TSO, academic organisations, civil society,...) capable of developing and coordinating the technical expertise that is required from the stakeholders in charge of delivering opinion, independently from the waste management organisations (WMO), on the safety of geological disposals. The SITEX programme of work is split into a set of six work packages that address technical and organisational issues allowing to propose a structure of the missions and operating mode of the future network. These issues relate on the one hand to the study of the potential for sharing and developing technical expertise practices amongst stakeholders, on the other hand on the ability to implement co-ordinated R and D programmes run by TSO in order to develop the scientific knowledge necessary to perform independent technical assessments. Two major perspectives are identified for the future of the SITEX network: its ability to foster co-operation between regulatory bodies, TSO, implementers and civil society with a view to enhancing common understanding of key safety issues and challenges and to identifying possible harmonisation of practices; the constitution of a scientific task force (mainly driven by TSO) for research definition and implementation at the European level allowing to improve the co-ordination of scientific programmes between TSO and developing its own skills and analytical tools, independently of the WMO. A comprehensive list of safety issues relevant to the development and implementation of a geological repository has

  15. Food waste generation and industrial uses: A review.

    Girotto, Francesca; Alibardi, Luca; Cossu, Raffaello

    2015-11-01

    Food waste is made up of materials intended for human consumption that are subsequently discharged, lost, degraded or contaminated. The problem of food waste is currently on an increase, involving all sectors of waste management from collection to disposal; the identifying of sustainable solutions extends to all contributors to the food supply chains, agricultural and industrial sectors, as well as retailers and final consumers. A series of solutions may be implemented in the appropriate management of food waste, and prioritised in a similar way to waste management hierarchy. The most sought-after solutions are represented by avoidance and donation of edible fractions to social services. Food waste is also employed in industrial processes for the production of biofuels or biopolymers. Further steps foresee the recovery of nutrients and fixation of carbon by composting. Final and less desirable options are incineration and landfilling. A considerable amount of research has been carried out on food waste with a view to the recovery of energy or related products. The present review aims to provide an overview of current debate on food waste definitions, generation and reduction strategies, and conversion technologies emerging from the biorefinery concept.

  16. Animal and industrial waste anaerobic digestion: USA status report

    Lusk, P.D. [Resource Development Associates, Washington, DC (United States)

    1996-01-01

    Pollutants from unmanaged animal and bio-based industrial wastes can degrade the environment, and methane emitted from decomposing wastes may contribute to global climate change. One waste management system prevents pollution and converts a disposal problem into a new profit center. Case studies of operating systems indicate that the anaerobic digestion of animal and industrial wastes is a commercially available bioconversion technology with considerable potential for providing profitable coproducts, including a cost-effective renewable fuel. Growth and concentration of the livestock industry create opportunities to properly dispose of the large quantities of manures generated at dairy, swine, and poultry farms. Beyond the farm, extension of the anaerobic digestion process to recover methane has considerable potential for certain classified industries - with a waste stream characterization similar to livestock manures. More than 35 example industries have been identified, and include processors of chemicals, fiber, food, meat, milk, and pharmaceuticals. Some of these industries already recover methane for energy. This status report examines some current opportunities for recovering methane from the anaerobic digestion of animal and industrial wastes in the US. Case studies of operating digesters, including project and maintenance histories, and the operator`s {open_quotes}lessons learned,{close_quotes} are included as a reality check. Factors necessary for successful projects, as well as a list of reasons explaining why some anaerobic digestion projects fail, are provided. The role of management is key; not only must digesters be well engineered and built with high-quality components, they must also be sited at facilities willing to incorporate the uncertainties of a new technology. Anaerobic digestion can provide monetary benefits and mitigate possible pollution problems, thereby sustaining development while maintaining environmental quality.

  18. Container for processing and disposing radioactive wastes and industrial wastes

    Araki, Kunio; Kasahara, Yuko; Kasai, Noboru; Sudo, Giichi; Ishizaki, Kanjiro.

    1978-01-01

    Purpose: To improve the performance of containers for radioactive wastes for ocean disposal and on-land disposal such as impact strength, chemical resistance, fire resistance, corrosion resistance, water impermeability and the like. Constitution: Steel fiber-reinforced concrete previously molded in a shape of a container is impregnated with polymerizable impregnating agent selected from the group consisting of a polymerizable monomer, liquid mixture of a polymerizable monomer and an oligomer, a polymer solution, a copolymer solution and the liquid mixture thereof. Then, the polymerizable impregnating agent is polymerized to solidify in the concrete by way of heat-polymerization or radiation-induced polymerization to form a waste container. The container thus obtained can be improved with the impact resistance and wear resistance and further improved with salt water resistance, acid resistance, corrosion resistance and solidity by the impregnation of the polymer, as well as can effectively be prevented from leaching out of radioactive substances.

  19. Bioprocessing of concentrated mixed hazardous industrial waste

    Wolfram, J.H.; Rogers, R.D.; Silver, G.; Attalla, A.; Prisc, M.

    1994-01-01

    The use of selected microorganisms for the degradation and/or the detoxification of hazardous organic compounds is gaining wide acceptance as an alternative waste treatment technology. This work describes the unique capabilities of an isolated strain of Pseudomonas for metabolizing methylated aromatic compounds. This strain of Pseudomonas putida Idaho is unique in that it can tolerate and grow under a layer of neat p-xylene. A bioprocess has been developed to degrade LLW and mixed wastes containing methylated aromatic compounds, i.e., pseudocumene, toluene and p-xylene. The process is now in the demonstration phase at a DOE facility and has been running for one year. Feed concentrations of 21200 ppm of the toxic organic substrate have been fed to the bioreactor. This report describes the results obtained thus far

  20. Radioactive waste: the poisoned legacy of the nuclear industry

    Rousselet, Y.

    2011-01-01

    The nuclear industry produces a huge amount of radioactive waste from one end to the other of the nuclear cycle: i.e. from mining uranium to uranium enrichment through reactor operating, waste reprocessing and dismantling nuclear power plants. Nuclear power is now being 'sold' to political leaders and citizens as an effective way to deal with climate change and ensure security of energy supplies. Nonetheless, nuclear energy is not a viable solution and is thus a major obstacle to the development of clean energy for the future. In addition to safety and security issues, the nuclear industry is, above all, faced with the huge problem of how to deal with the waste it produces and for which it has no solution. This ought to put a brake on the nuclear industry, but instead, against all expectations, its development continues to gather pace. (author)

  1. Solid waste management in the hospitality industry: a review.

    Pirani, Sanaa I; Arafat, Hassan A

    2014-12-15

    Solid waste management is a key aspect of the environmental management of establishments belonging to the hospitality sector. In this study, we reviewed literature in this area, examining the current status of waste management for the hospitality sector, in general, with a focus on food waste management in particular. We specifically examined the for-profit subdivision of the hospitality sector, comprising primarily of hotels and restaurants. An account is given of the causes of the different types of waste encountered in this sector and what strategies may be used to reduce them. These strategies are further highlighted in terms of initiatives and practices which are already being implemented around the world to facilitate sustainable waste management. We also recommended a general waste management procedure to be followed by properties of the hospitality sector and described how waste mapping, an innovative yet simple strategy, can significantly reduce the waste generation of a hotel. Generally, we found that not many scholarly publications are available in this area of research. More studies need to be carried out on the implementation of sustainable waste management for the hospitality industry in different parts of the world and the challenges and opportunities involved.

  2. Classification of radioactive wastes produced by the nuclear industry

    2013-01-01

    This document first indicates the origins of radioactive wastes (mainly electronuclear industry), and the composition of spent fuel, and that only fission products and minor actinides are considered as radioactive wastes whereas uranium and plutonium can be used as new fuel after recycling. The classification of radioactive wastes is indicated in terms of radioactivity level and radionuclide half-life: high level (0.2 per cent of the total waste volume but 96 per cent of total waste radioactivity), medium level long life (3 per cent of volume, 4 per cent of radioactivity), low level long life (7 per cent of volume, 0.1 per cent of radioactivity), low and medium level and short life (63 per cent of volume and 0.02 per cent of radioactivity), very low level (27 per cent of volume and less than 0.01 per cent of radioactivity). An overview of radioactive waste processing and storage in France is presented for each category. Current and predicted volumes are indicated for each category. The main challenges are briefly addressed: spent fuel recycling, waste valorisation by fourth-generation reactors. Processing locations in France and in the World are indicated. Some key figures are provided: 2 kg of radioactive waste are produced per inhabitant and per year, and waste management costs represent 5 per cent of the total cost of produced electricity

  3. Direction of CRT waste glass processing: electronics recycling industry communication.

    Mueller, Julia R; Boehm, Michael W; Drummond, Charles

    2012-08-01

    Cathode Ray Tube, CRT, waste glass recycling has plagued glass manufacturers, electronics recyclers and electronics waste policy makers for decades because the total supply of waste glass exceeds demand, and the formulations of CRT glass are ill suited for most reuse options. The solutions are to separate the undesirable components (e.g. lead oxide) in the waste and create demand for new products. Achieving this is no simple feat, however, as there are many obstacles: limited knowledge of waste glass composition; limited automation in the recycling process; transportation of recycled material; and a weak and underdeveloped market. Thus one of the main goals of this paper is to advise electronic glass recyclers on how to best manage a diverse supply of glass waste and successfully market to end users. Further, this paper offers future directions for academic and industry research. To develop the recommendations offered here, a combination of approaches were used: (1) a thorough study of historic trends in CRT glass chemistry; (2) bulk glass collection and analysis of cullet from a large-scale glass recycler; (3) conversations with industry members and a review of potential applications; and (4) evaluation of the economic viability of specific uses for recycled CRT glass. If academia and industry can solve these problems (for example by creating a database of composition organized by manufacturer and glass source) then the reuse of CRT glass can be increased.

  4. Chemical analysis for waste management in paint industries

    Nawaz, Z.; Naveed, S.; Shiekh, N.A.; Sagheer, K.

    2005-01-01

    The chemical analysis of paint industries waste has been carried out; the main emission sources are the heating of raw materials and lacquer. Also the waste from other applications and production contains high concentration of heavy metals, VOC's, COD, TDS with notable acidity and alkalinity. Based on the analysis it was observed that the major losses of production could be minimized. Further toxic effects of the waste material can be minimized. In this reference measures to minimize production losses should be adopted along with the proper management. These laboratory results also lead to the areas of emissions and waste production during manufacturing process. Solutions have been proposed for process development and integrated waste minimization.

  5. Industrial-Scale Processes For Stabilizing Radioactively Contaminated Mercury Wastes

    Broderick, T. E.; Grondin, R.

    2003-01-01

    This paper describes two industrial-scaled processes now being used to treat two problematic mercury waste categories: elemental mercury contaminated with radionuclides and radioactive solid wastes containing greater than 260-ppm mercury. The stabilization processes were developed by ADA Technologies, Inc., an environmental control and process development company in Littleton, Colorado. Perma-Fix Environmental Services has licensed the liquid elemental mercury stabilization process to treat radioactive mercury from Los Alamos National Laboratory and other DOE sites. ADA and Perma-Fix also cooperated to apply the >260-ppm mercury treatment technology to a storm sewer sediment waste collected from the Y-12 complex in Oak Ridge, TN

    Sixt, H

    1985-06-01

    Organically high polluted waste water sets special claims for an economical purification and the process treatment. Up to now these waste waters are being purified by anaerobic processes with simultaneous biogas generation. The fourstep anaerobic degradation is influenced by a lot of important parameters. Extensive researchers in the field of anaerobic microbiology has improved the knowledge of the fundamental principles. Parallel the reactor technology is developed worldwide. In general it seems that the fixed-film-reactor with immobilized bacteria has the best future to purify organically high polluted industrial waste water with short retention times under stable operation conditions.

  8. Disposal of by-products in olive oil industry: waste-to-energy solutions

    Caputo, Antonio C.; Scacchia, Federica; Pelagagge, Pacifico M.

    2003-01-01

    Olive oil production industry is characterized by relevant amounts of liquid and solid by-products [olive mill wastewater (OMW) and olive husk (OH)], and by economical, technical and organizational constraints that make difficult the adoption of environmentally sustainable waste disposal approaches. In this context, waste treatment technologies aimed at energy recovery represent an interesting alternative. In the paper, a technical and economical analysis of thermal disposal plant solutions with energy recovery has been carried out. The considered plants enable the combined treatment of OMW and OH which, although penalizes the energy recovery, proves to be feasible and profitable in a future legislative scenario when stricter limitation on OMW disposal will force oil producers to bear high disposal costs. Results are compared by using economic performance measures, including revenues from produced energy and avoided disposal costs. A sensitivity and risk analysis is also performed in order to assess the economic profitability of the proposed solutions

  9. Technical issues in licensing low-level radioactive waste facilities

    Junkert, R. [California Dept. of Health Services, CA (United States)

    1993-03-01

    The California Department of Health Service spent two years in the review of an application for a low-level radioactive waste disposal facility in California. During this review period a variety of technical issues had to be evaluated and resolved. One of the first issues was the applicability and use of NRC guidance documents for the development of LLW disposal facilities. Other technical issues that required intensive evaluations included surface water hydrology, seismic investigation, field and numerical analysis of the unsaturated zone, including a water infiltration test. Source term verification became an issue because of one specific isotope that comprised more than 90% of the curies projected for disposal during the operational period. The use of trench liners and the proposed monitoring of the unsaturated zone were reviewed by a highly select panel of experts to provide guidance on the need for liners and to ensure that the monitoring system was capable of monitoring sufficient representative areas for radionuclides in the soil, soil gas, and soil moisture. Finally, concerns about the quality of the preoperational environmental monitoring program, including data, sample collection procedures, laboratory analysis, data review and interpretation and duration of monitoring caused a significant delay in completing the licensing review.

  10. ``Recycling'' Nuclear Power Plant Waste: Technical Difficulties and Proliferation Concerns

    Lyman, Edwin

    2007-04-01

    One of the most vexing problems associated with nuclear energy is the inability to find a technically and politically viable solution for the disposal of long-lived radioactive waste. The U.S. plan to develop a geologic repository for spent nuclear fuel at Yucca Mountain in Nevada is in jeopardy, as a result of managerial incompetence, political opposition and regulatory standards that may be impossible to meet. As a result, there is growing interest in technologies that are claimed to have the potential to drastically reduce the amount of waste that would require geologic burial and the length of time that the waste would require containment. A scenario for such a vision was presented in the December 2005 Scientific American. While details differ, these technologies share a common approach: they require chemical processing of spent fuel to extract plutonium and other long-lived actinide elements, which would then be ``recycled'' into fresh fuel for advanced reactors and ``transmuted'' into shorter-lived fission products. Such a scheme is the basis for the ``Global Nuclear Energy Partnership,'' a major program unveiled by the Department of Energy (DOE) in early 2006. This concept is not new, but has been studied for decades. Major obstacles include fundamental safety issues, engineering feasibility and cost. Perhaps the most important consideration in the post-9/11 era is that these technologies involve the separation of plutonium and other nuclear weapon-usable materials from highly radioactive fission products, providing opportunities for terrorists seeking to obtain nuclear weapons. While DOE claims that it will only utilize processes that do not produce ``separated plutonium,'' it has offered no evidence that such technologies would effectively deter theft. It is doubtful that DOE's scheme can be implemented without an unacceptable increase in the risk of nuclear terrorism.

  11. Branch technical position for performance assessment of low-level radioactive waste disposal facilities

    Campbell, A.C.; Abramson, L.; Byrne, R.M.

    1994-01-01

    The U.S. Nuclear Regulatory Commission has developed a Draft Branch Technical Position on Performance Assessment of Low-Level Radioactive Waste Disposal Facilities. The draft technical position addresses important issues in performance assessment modeling and provides a framework and technical basis for conducting and evaluating performance assessments in a disposal facility license application. The technical position also addresses specific technical policy issues and augments existing NRC guidance pertaining to LLW performance assessment

  12. Hazardous waste management in Chilean main industry: An overview

    Navia, Rodrigo; Bezama, Alberto

    2008-01-01

    The new 'Hazardous Waste Management Regulation' was published in the Official Newspaper of the Chilean Republic on 12 June 2003, being in force 365 days after its publication (i.e., 12 June 2004). During the next 180 days after its publication (i.e., until 12 December 2004), each industrial facility was obligated to present a 'Hazardous Waste Management Plan' if the facility generates more than 12 ton/year hazardous wastes or more than 12 kg/year acute toxic wastes. Based on the Chilean industrial figures and this new regulation, hazardous waste management plans were carried out in three facilities of the most important sectors of Chilean industrial activity: a paper production plant, a Zn and Pb mine and a sawmill and wood remanufacturing facility. Hazardous wastes were identified, classified and quantified in all facilities. Used oil and oil-contaminated materials were determined to be the most important hazardous wastes generated. Minimization measures were implemented and re-use and recycling options were analyzed. The use of used oil as alternative fuel in high energy demanding facilities (i.e., cement facilities) and the re-refining of the used oil were found to be the most suitable options. In the Zn and Pb mine facility, the most important measure was the beginning of the study for using spent oils as raw material for the production of the explosives used for metals recovery from the rock. In Chile, there are three facilities producing alternative fuels from used oil, while two plants are nowadays re-refining oil to recycle it as hydraulic fluid in industry. In this sense, a proper and sustainable management of the used oil appears to be promissory

    1999-04-15

    Previous studies have shown that an effective general treatment for hazardous wastes is sorption of the waste onto a specially prepared, macroporous coal char followed by gasification of the mixture in reverse mode. In the present study, an industrial waste comprised of styrene manufacturing and petroleum byproducts was gasified, and the waste, coal, virgin char, and char/waste mixture (before and after gasification) were examined by various instrumental methods, infrared, nuclear magnetic resonance, gas chromatography, gas chromatography/mass spectroscopy, scanning electron microscopy, and ultimate and proximate analyses, to determine which methods give useful information. The composition of the waste was found to be 38% water, 27% inorganic, and 35% organic. NMR showed that the organic components are a mixture of aliphatic and olefinic/aromatics. About 8% of the sludge is chromatographable and GC/MS revealed the presence of aromatics and polyaromatic hydrocarbons. Solid-state NMR showed that the sludge components are strongly immobilized on the char up to a 1:1 (wt:wt) ratio. SEM results showed changes in the char macroporous surface as waste is incorporated by the char and as the mixture is subsequently gasified. In addition, a portion of the elemental content of the char surface was revealed by energy dispersive (EDAX) measurements. IR photoaccoustic spectroscopy showed that peaks attributable to aqueous and organic fractions of the waste disappear upon gasification. 19 refs., 7 figs., 5 tabs.

    Cassitto, L.; Gallarini, V.; Magnani, P.; Rizzi, A. (Politecnico di Milano, Milan (Italy). Impianti Condizionamento e Fisica Tecnica Artea, Milan (Italy))

    A survey of European Communities proposed air pollution standards is coupled with an examination of the technical feasibility of building and operating municipal solid waste incineration plants that can successfully meet those standards. The results of the analysis indicate that modern incineration plants equipped with cogeneration and current-technology materials and energy recovery systems offer a significant contribution to meeting Italian national energy requirements and contemporaneously provide a decisive answer to the pressing need for safe and effective urban area waste disposal. The paper cautions however any final decision making must be based on extensive cost benefit analyses to determine the optimum combination of incinerator plant energy production and pollution control systems.

  20. The 1996 meeting of the national technical workgroup on mixed waste thermal treatment

    1996-01-01

    The National Technical Workgroup on Mixed Waste Thermal Treatment held its annual meeting in Atlanta Georgia on March 12-14, 1996. The National Technical Workgroup (NTW) and this meeting were sponsored under an interagency agreement between EPA and DOE. The 1996 Annual Meeting was hosted by US DOE Oak Ridge Operations in conjunction with Lockheed Martin Energy Systems - Center for Waste Management. A new feature of the annual meeting was the Permit Writer Panel Session which provided an opportunity for the state and federal permit writers to discuss issues and potential solutions to permitting mixed waste treatment systems. In addition, there was substantial discussion on the impacts of the Waste Combustion Performance Standards on mixed waste thermal treatment which are expected to proposed very soon. The 1996 meeting also focussed on two draft technical resource documents produced by NTW on Waste Analysis Plans and Compliance Test Procedures. Issues discussed included public involvement, waste characterization, and emission issues

    1997-12-31

    Recycling problem for various kind of waste is solved by processing the waste to ecological depositable products with multibarrier structure. In order to form a multibarrier structure the ecologically incompatible substances may be diluted and chemically bound until their recycling products gain a structure like natural mineral or glass (I. barrier). After that, remineralized materials are converted into a new product by melting or powder technology using an ecological compatible type of waste as a matrix phase (II. barrier). Waste which are treated this way could be applied to produce ceramic building materials and goods such as floor tiles, stone pavement and casting products. Industrial waste from the metallurgical factory in Latvia ``Liepajas metalurgs`` are metallurgical slag, filter dust, etching waste and sewage used in technologies. The main constituents of chemical compositions of these waste are: Fe, Ca, Si, Mg, Al, Mn etc. In some types of waste a small amount of ecologically risky elements such as Cr, Ni, Zr, Sn and Pb can occur. The combination of metallurgical waste with peat ashes from Riga thermal power station, oil shale ashes or glass waste under controlled sintering procedure gives bulk materials with surface or/and bulkcrystallization. The structure of glass-ceramics built this way may prevent the migration of ecologically risky elements into environment due to corrosion or friction. Physical-chemical properties and thermal behaviour (DTA, dilatometry, melting) of waste define the range of sintering for production of glass-ceramics (powder technology) and decorative glass-ceramic materials (melting and powder technology).

    The global interest in renewable energy is attributed to the decline in fossil fuel sources and the need for technical, economic, social and environmental sustainability. This study focused on the new techniques that have been developed for the use of biomass for energy from wood wastes from the forest-based industry. As an energy source, wood waste contributes positively to the environment by reducing environmental problems related to contamination of soil, air and water through improper disposal of waste. Biomass gasification has the advantage of converting biomass into a combustible gas that can be used for heat generation, electricity and synthesis of chemicals. Syngas produced from gasification of eucalyptus residues has significant potential, with an average High Heating Value of 6.60 MJ/m{sup 3}, and regular composition during the process, with predominance of carbon monoxide, followed by hydrogen, carbon dioxide and methane.

  5. Biotreatment of industrial and hazardous waste

    Levin, M.A.; Gealt, M.A.

    1993-01-01

    This book attempts to approach the topic of biodegradation of hazardous wastes in a holistic fashion. The issues of science, engineering and regulation are all addressed. As much as possible, both theoretical and practical considerations have been dealt with. Selection of bacteria for the specific purpose of degrading compounds is discussed at the bench-scale to the field level. Engineering theory as applied to growth on toxic substances is discussed. The legal issues are covered. There are also several examples of field studies indicating the current usage of biodegradation, both within reactors and in situ. The use of biodegradation is compared with other mechanisms of disposal, in terms of time limitations, degradation limitations and, perhaps most important, cost. Individual papers have been processed separately for inclusion in the appropriate data bases

  9. Exergetic comparison of food waste valorization in industrial bread production

    Zisopoulos, Filippos K.; Moejes, Sanne N.; Rossier-Miranda, Francisco J.; Goot, Atze Jan van der; Boom, Remko M.

    2015-01-01

    This study compares the thermodynamic performance of three industrial bread production chains: one that generates food waste, one that avoids food waste generation, and one that reworks food waste to produce new bread. The chemical exergy flows were found to be much larger than the physical exergy consumed in all the industrial bread chains studied. The par-baked brown bun production chain had the best thermodynamic performance because of the highest rational exergetic efficiency (71.2%), the lowest specific exergy losses (5.4 MJ/kg brown bun), and the almost lowest cumulative exergy losses (4768 MJ/1000 kg of dough processed). However, recycling of bread waste is also exergetically efficient when the total fermented surplus is utilizable. Clearly, preventing material losses (i.e. utilizing raw materials maximally) improves the exergetic efficiency of industrial bread chains. In addition, most of the physical (non-material related) exergy losses occurred at the baking, cooling and freezing steps. Consequently, any additional improvement in industrial bread production should focus on the design of thermodynamically efficient baking and cooling processes, and on the use of technologies throughout the chain that consume the lowest possible physical exergy. - Highlights: • Preventing material losses is the best way to enhance the exergetic efficiency. • Most of the physical exergy losses occur at the baking, cooling and freezing steps. • Par-baking “saves” chemical exergy but consumes an equal amount of physical exergy

  10. Thermoexoemission detectors for monitoring radioactive contamination of industrial waste waters

    Obukhov, V.T.; Sobolev, I.A.; Khomchik, L.M.

    1987-01-01

    Detectors on base of BeO(Na) monocrystals with thermoemission to be used for monitoring radioactive contamination of industrial waste waters are suggested. The detectors advantages are sensitivity to α and low-ehergy β radiations, high mechanical strength and wide range of measurements. The main disadvantage is the necessity of working in red light

  12. Direction of CRT waste glass processing: Electronics recycling industry communication

    Mueller, Julia R.; Boehm, Michael W.; Drummond, Charles

    2012-01-01

    Highlights: ► Given a large flow rate of CRT glass ∼10% of the panel glass stream will be leaded. ► The supply of CRT waste glass exceeded demand in 2009. ► Recyclers should use UV-light to detect lead oxide during the separation process. ► Recycling market analysis techniques and results are given for CRT glass. ► Academic initiatives and the necessary expansion of novel product markets are discussed. - Abstract: Cathode Ray Tube, CRT, waste glass recycling has plagued glass manufacturers, electronics recyclers and electronics waste policy makers for decades because the total supply of waste glass exceeds demand, and the formulations of CRT glass are ill suited for most reuse options. The solutions are to separate the undesirable components (e.g. lead oxide) in the waste and create demand for new products. Achieving this is no simple feat, however, as there are many obstacles: limited knowledge of waste glass composition; limited automation in the recycling process; transportation of recycled material; and a weak and underdeveloped market. Thus one of the main goals of this paper is to advise electronic glass recyclers on how to best manage a diverse supply of glass waste and successfully market to end users. Further, this paper offers future directions for academic and industry research. To develop the recommendations offered here, a combination of approaches were used: (1) a thorough study of historic trends in CRT glass chemistry; (2) bulk glass collection and analysis of cullet from a large-scale glass recycler; (3) conversations with industry members and a review of potential applications; and (4) evaluation of the economic viability of specific uses for recycled CRT glass. If academia and industry can solve these problems (for example by creating a database of composition organized by manufacturer and glass source) then the reuse of CRT glass can be increased.

    2017-01-01

    Highlights: • Animal fats in blend with diesel fuel for energy valorification through combustion. • Animal waste from tanneries as fuel and for biogas production. • Experimental tests using animal fats as fuel for diesel engines. • Experimental tests modifying the characteristic parameters. - Abstract: Secondary products from food and leather industries are regarded as animal wastes. Conversion of these animal wastes into fuels represents an energy recovery solution not only because of their good combustion properties, but also from the viewpoint of supply stability. A tannery factory usually processes 60–70 t/month of crude leathers, resulting in 12–15 t/month of waste. Fats, which can be used as the input fuel for diesel engines (in crude state or as biodiesel), represent 10% of this animal waste, while the rest are proteins that can be used to generate biogas through anaerobic digestion. Herein, we analyse two approaches to the use of animal waste from tanneries: as fuel for diesel engines and for biogas generation for heat production. Diesel fuelling and fuelling by animal wastes are compared in terms of the engine performance and pollutant emissions. The effects of animal waste usage on the pollutant emissions level, exhaust gas temperature, indicated mean effective pressure, maximum pressure, and engine efficiency are analysed. The energy recovery technologies for animal waste, which are analysed in this work, can be easily implemented and can simultaneously solve the problem posed by animal wastes by using them as an alternative to fossil fuels. Animal fats can be considered an excellent alternative fuel for diesel engines without major constructive modifications.

    Industrial districts show characteristics that can be exploited by developing plant solutions studied for their special configuration and not simply extended from single unit models. In the paper a waste-to-energy plant for the chair industrial district in Friuli Venezia Giulia (North Eastern Italy) is described. It has been designed directly involving the University of Udine and can be considered an example of how technology innovation can be promoted by universities, especially in the case of small firms which have limited R and D resources. It is shown how industrial refuse becomes a chance of competitive advantage for the whole district due to its energy recovery in a plant unique for the type of waste processed. Input, combustion, energy recovery and cleaning sections are described in details, underlining innovative approaches and solutions [it

    Mohammad Amin Karami

    2015-01-01

    Full Text Available Aims: In this study, management of industrial waste in industries located between Tehran and Karaj in 2009-2010 was examined. Materials and Methods: This is a cross-sectional study which was done by site survey (Iranian environmental protection organization questionnaire usage and results analysis. This questionnaire was consisted of 45 questions about industrial waste, quantity, quality, and management. A total number of industries with over 50 employees was 283, and Stratified sampling method was used. Sample of size 50 was selected from 283cases. Results: The major hazardous waste-generating industries include chemical and plastic. Private sectors disposed 45% of generated waste. Majority of wastes were buried (62%, and only 17% of industrial waste was recycled. Conclusion: For hazardous waste reduction in this zone and health and economic attractions, the opportunity for reuse and recovery for these wastes must maximize in short-term and burial of industrial waste must be minimized. Industries such as chemical-plastic and electronics which have higher hazardous waste, in long-term, must be replaced with other industries such as wood cellulose and paper that have lower hazardous waste production rate.

  1. Valorization of mine rejects and industrial wastes for the recovery of some strategic and critical metals

    Sreenivas, T.; Dey, G K.; Anand Rao, K.

    2017-01-01

    Strategic and critical metals (SCM) resources form important components in safety and security design of any country. Uneven distribution of SCM resources as well as lack of technical expertise in manufacture of end-products makes many nations vulnerable to external pulls and pressures. India is making determined bid to surmount these difficulties by constantly upgrading its scientific and engineering expertise to address issues related to resources and materials manufacturing technologies. It is a well known fact that India is a resource starved country with respect to many of the strategic and critical metals (SCM). The demand for the SCM is met mostly by import of finished products and to a lesser extent by recycle of used products. In these days of growing inclination towards 'sustainable development' valorization of industrial waste for securing valuable metals including those of SCM category is worth pursuing, more so for a country like India. With this premise, we present in this paper representative case studies which depict technical feasibility of using industrial waste as a source for some important SCM, namely Nd, Y, Co and W. The wastes used for valorization are the mine tailings or rejects of different ores like copper, gold, uranium and fly ash generated from a coal-fired thermal power plant. (author)

  2. Technical and economic optimization study for HLW waste management

    Deffes, A.

    1989-01-01

    This study was conducted to assess the technical and economic aspects of high level waste (HLW) management with the objective of optimizing the interim storage duration and the dimensions of the underground repository site. The procedure consisted in optimizing the economic criterion under specified constraints. The results are intended to identify trends and guide the choice from among available options; simple and highly flexible models were therefore used in this study, and only nearfield thermal constraints were taken into consideration. Because of the present uncertainty on the physicochemical properties of the repository environment and on the unit cost figures, this study focused on developing a suitable method rather than on obtaining definitive results. With the physical and economic data bases used for the two media investigated (granite and salt) the optimum values found show that it is advisable to minimize the interim storage time, and that the geological repository should feature a high degree of spatial dilution. These results depend to a considerable extent on the assumption of high interim storage costs

  3. Balancing the technical, administrative, and institutional forces in defense waste management

    Hindman, T.B.

    1988-01-01

    Defense radioactive waste results from the Department of Energy's (DOE) national defense and nuclear weapons production activities. In 1983, the President submitted to Congress the Defense Waste Management Plan (DWMP) for defense high-level and transuranic wastes. The Plan proposed a workable approach for the final disposition of these wastes. The Department is still following the path laid out in this Plan. The proper management of this waste requires that technical, administrative, and institutional forces which are often neither well understood nor well documented be properly balanced. This paper clarifies the role these three forces play in the Defense waste management programs and provides examples of their impacts on specific programs

  4. The Recovery of Zinc Heavy Metal from Industrial Liquid Waste

    Panggabean, Sahat M.

    2000-01-01

    It had been studied the recovery of zinc heavy metal from liquid waste of electroplating industry located at East Jakarta. The aim of this study was to minimize the waste arisen from industrial activities by taking out zinc metal in order to reused on-site. The method of recovery was two steps precipitation using NaOH reagent and pH variation. The first step of precipitation at pH optimum around 6 yielded iron metal. The second step at pH optimum around 10 yielded zinc metal. The zinc metal was taken out assessed to the possibility of reused at that fabric. By applying its, it will yield the volume reduction of sludge waste about 36.1% or 53.2% of zinc metal containing in the waste. It means the cost of waste treatment will be lower. Beside its, the effluent arisen from the method had fulfill the maximum limit and it allowed to release to the environment. (author)

  5. Methods for recovering precious metals from industrial waste

    Canda, L.; Heput, T.; Ardelean, E.

    2016-02-01

    The accelerated rate of industrialization increases the demand for precious metals, while high quality natural resources are diminished quantitatively, with significant operating costs. Precious metals recovery can be successfully made from waste, considered to be secondary sources of raw material. In recent years, concerns and interest of researchers for more increasing efficient methods to recover these metals, taking into account the more severe environmental protection legislation. Precious metals are used in a wide range of applications, both in electronic and communications equipment, spacecraft and jet aircraft engines and for mobile phones or catalytic converters. The most commonly recovered precious metals are: gold from jewellery and electronics, silver from X- ray films and photographic emulsions, industrial applications (catalysts, batteries, glass/mirrors), jewellery; platinum group metals from catalytic converters, catalysts for the refining of crude oil, industrial catalysts, nitric acid manufacturing plant, the carbon-based catalyst, e-waste. An important aspect is the economic viability of recycling processes related to complex waste flows. Hydrometallurgical and pyrometallurgical routes are the most important ways of processing electrical and electronic equipment waste. The necessity of recovering precious metals has opened new opportunities for future research.

    English, T.; Miller, C.; Bullard, E.; Campbell, R.; Chockie, A.; Divita, E.; Douthitt, C.; Edelson, E.; Lees, L.

    1977-01-01

    The technical status of the old U.S. mailine program for high level radioactive nuclear waste management, and the newly-developing program for disposal of unreprocessed spent fuel was assessed. The method of long term containment for both of these waste forms is considered to be deep geologic isolation in bedded salt. Each major component of both waste management systems is analyzed in terms of its scientific feasibility, technical achievability and engineering achievability. The resulting matrix leads to a systematic identification of major unresolved technical or scientific questions and/or gaps in these programs.

  10. Conversion of transuranic waste to low level waste by decontamination: a technical and economic evaluation

    Allen, R.P.; Hazelton, R.F.

    1984-12-01

    A study was conducted to evaluate the technical and economic feasibility of using in-situ decontamination techniques to convert glove boxes and other large TRU-contaminated components directly into LLW. The results of the technical evaluation indicate that in-situ decontamination of these types of components to non-TRU levels is technically feasible. Applicable decontamination techniques include electropolishing, hand scrubbing, chemical washes/sprays, strippable coatings and Freon spray-cleaning. The removal of contamination from crevices and other holdup areas remains a problem, but may be solved through further advances in decontamination technology. Also, the increase in the allowable maximum TRU level from 10 nCi/g to 100 nCi/g as defined in DOE Order 5820.2 reduces the removal requirement and facilitates measurement of the remaining quantities. The major emphasis of the study was on a cost/benefit evaluation that included a review and update of previous analyses and evaluations of TRU-waste volume reduction and conversion options. The results of the economic evaluation show, for the assumptions used, that there is a definite cost incentive to size reduce large components, and that decontamination of sectioned material has become cost competitive with the size reduction options. In-situ decontamination appears to be the lowest cost option when based on routine-type operations conducted by well-trained and properly equipped personnel. 16 references, 1 figure, 7 tables

  11. Harmonization of industrial and oilfield waste management issues in Alberta

    Halla, S.

    1999-01-01

    There has been an ongoing discussion concerning the harmonization of waste management requirements within Alberta between the Alberta Energy and Utilities Board (EUB) and Alberta Environment (AENV), with the ultimate goal of publishing a memorandum of understanding (MOU) that will lay out the division of responsibilities between the two authorities on this matter. An overview is included of waste management in Alberta and of the harmonization agreements attained to date, with a stress on oil field waste issues. The EUB and AENV developed a MOE on the harmonization of waste management in Alberta, and a discussion is made of the concept of equivalency, which is used in the development of 'EUB guide 58: oilfield waste management requirements for the upstream petroleum industry' and will be a guiding principle for the MOU. Although the EUB's processes for waste management will not be exactly the same as AENV's, the EUB has made the commitment that, as a minimum, the requirements will provide the same level of environmental protection and public safety equivalent to that provided by AENV

  12. Conversion of industrial food wastes by Alcaligenes latus into polyhydroxyalkanoates.

    Yu, P H; Chua, H; Huang, A L; Ho, K P

    1999-01-01

    Broader usage of biodegradable plastics in packaging and disposable products as a solution to environmental problems would heavily depend on further reduction of costs and the discovery of novel biodegradable plastics with improved properties. As the first step in our pursuit of eventual usage of industrial food wastewater as nutrients for microorganisms to synthesise environmental-friendly bioplastics, we investigated the usage of soya wastes from a soya milk dairy, and malt wastes from a beer brewery plant as the carbon sources for the production of polyhydroxyalkanoates (PHA) by selected strain of microorganism. Bench experiments showed that Alcaligenes latus DSM 1124 used the nutrients from malt and soya wastes to biosynthesise PHAs. The final dried cell mass and specific polymer production of A. latus DSM 1124 were 32g/L and 70% polymer/cells (g/g), 18.42 g/L and 32.57% polymer/cell (g/g), and 28 g/L and 36% polymer/cells (g/g), from malt waste, soya waste, and from sucrose, respectively. These results suggest that many types of food wastes might be used as the carbon source for the production of PHA.

  14. Biopower Technical Assessment: State of the Industry and the Technology

    Bain, R. L.; Amos, W. P.; Downing, M.; Perlack, R. L.

    2003-01-01

    This report provides an assessment of the state of the biopower industry and the technology for producing electricity and heat from biomass. Biopower (biomass-to-electricity generation), a proven electricity generating option in the United States and with about 11 GW of installed capacity, is the single largest source of non-hydro renewable electricity. This 11 GW of capacity encompasses about 7.5 GW of forest product industry and agricultural industry residues, about 3.0 GW of municipal solid waste-based generating capacity and 0.5 GW of other capacity such as landfill gas based production. The electricity production from biomass is being used and is expected to continue to be used as base load power in the existing electrical distribution system. An overview of sector barriers to biopower technology development is examined in Chapter 2. The discussion begins with an analysis of technology barriers that must be overcome to achieve successful technology pathways leading to the commercialization of biomass conversion and feedstock technologies. Next, an examination of institutional barriers is presented which encompasses the underlying policies, regulations, market development, and education needed to ensure the success of biopower. Chapter 3 summarizes biomass feedstock resources, characteristics, availability, delivered prices, requirements for processing, and the impediments and barriers to procurement. A discussion of lessons learned includes information on the California biomass energy industry, lessons from commercial biopower plants, lessons from selected DOE demonstration projects, and a short summary of the issues considered most critical for commercial success is presented in Chapter 4. A series of case studies, Chapter 5, have been performed on the three conversion routes for Combined Heat and Power (CHP) applications of biomass--direct combustion, gasification, and cofiring. The studies are based on technology characterizations developed by NREL and EPRI

  15. Physical and thermal waste utilisation in the nonferrous metal industry; Stoffliche und thermische Abfallverwertung in der Nichteisenmetallindustrie

    Sowa, F. [DMT-Gesellschaft fuer Forschung und Pruefung mbH, Essen (Germany)

    1998-09-01

    In its amended form the German Household Waste Technical Code favours physical and thermal utilisation of wastes against dumping. Industrial processes offer various ways of utilising wastes with a high calorific value, e.g. in nonferrous metal production. Besides portraying this branch of industry in Germany the present paper investigates to what extent this topic has already found coverage and what potential it holds for the utilisation of wastes. By way of example it describes a successful demonstration of the physical utilisation of sewage sludge in lead production. [Deutsch] Die Neugestaltung der TA Siedlungsabfall favorisiert die thermische und stoffliche Verwertung von Abfallstoffen gegenueber der Deponierung. Moeglichkeiten fuer die Verwertung heizwertreicher Abfaelle bieten auch industrielle Produktionsprozesse, z.B. auch in der Nichteisenmetallerzeugung. Neben einer Charakterisierung der Branche wird untersucht, inwieweit dieses Thema bereits aufgegriffen worden ist und welches Verwertungspotential zur Verfuegung steht. An einem Beispiel wird die erfolgreiche Demonstration der stofflichen Verwertung von Klaerschlamm in der Bleierzeugung dargestellt. (orig.)

  16. US Department of Energy mixed waste characterization, treatment, and disposal focus area technical baseline development process

    Roach, J.A.; Gombert, D.

    1996-01-01

    The US Department of Energy (DOE) created the Mixed Waste Characterization, Treatment, and Disposal Focus Area (MWFA) to develop and facilitate implementation of technologies required to meet its commitments for treatment of mixed wastes under the Federal Facility Compliance Act (FFCA), and in accordance with the Land Disposal Restrictions (LDR) of the Resource Conservation and Recovery Act (RCRA). Mixed wastes include both mixed low-level waste (MLLW) and mixed transuranic (MTRU) waste. The goal of the MWFA is to develop mixed waste treatment systems to the point of implementation by the Environmental Management (EM) customer. To accomplish this goal, the MWFA is utilizing a three step process. First, the treatment system technology deficiencies were identified and categorized. Second, these identified needs were prioritized. This resulted in a list of technical deficiencies that will be used to develop a technical baseline. The third step, the Technical Baseline Development Process, is currently ongoing. When finalized, the technical baseline will integrate the requirements associated with the identified needs into the planned and ongoing environmental research and technology development activities supported by the MWFA. Completion of this three-step process will result in a comprehensive technology development program that addresses customer identified and prioritized needs. The MWFA technical baseline will be a cost-effective, technically-defensible tool for addressing and resolving DOE's mixed waste problems

  20. Savannah River Site sample and analysis plan for Clemson Technical Center waste

    Hagstrom, T.

    1998-04-01

    The purpose of this sampling and analysis plan is to determine the chemical, physical and radiological properties of the SRS radioactive Polychlorinated Biphenyl (PCB) liquid waste stream, to verify that it conforms to Waste Acceptance Criteria of the Department of Energy (DOE) East Tennessee Technology Park (ETTP) Toxic Substance Control Act (TSCA) Incineration Facility. Waste being sent to the ETTP TSCA Incinerator for treatment must be sufficiently characterized to ensure that the waste stream meets the waste acceptance criteria to ensure proper handling, classification, and processing of incoming waste to meet the Waste Storage and Treatment Facility's Operating Permits. This sampling and analysis plan is limited to WSRC container(s) of homogeneous or multiphasic radioactive PCB contaminated liquids generated in association with a treatability study at Clemson Technical Center (CTC) and currently stored at the WSRC Solid Waste Division Mixed Waste Storage Facility (MWSF)

  1. Alpha waste incineration prototype incinerator and industrial project

    Caramelle, D.; Meyere, A.

    1988-01-01

    To meet our requirements with respect to the processing of solid alpha wastes, a pilot cold incinerator has been used for R and D. This unit has a capacity of 5 kg/hr. The main objectives assigned to this incineration process are: a good reduction factor, controlled combustion, ash composition compatible with plutonium recovery, limited secondary solid and fluid wastes, releases within the nuclear and chemical standards, and in strict observance of the confinement and criticality safety rules. After describing the process we will discuss the major results of the incineration test campaigns with representative solid wastes (50 % PVC). We will then give a description of an industrial project with a capacity of 7 kg/hr, followed by a cost estimate

  2. The role of risk perception and technical information in scientific debates over nuclear waste storage

    Jenkins-Smith, Hank C.; Silva, Carol L.

    1998-01-01

    This article examines how members of the lay public factor risk perceptions, trust and technical information from differing scientific sources into policy judgements about potentially hazardous facilities. Focusing on radwaste storage repositories, we examine how members of the public filter new information about potential hazards through risk perceptions, and adjust their own beliefs about risks in light of that information. Scientists play a large (and increasing) role in public policy debates concerning nuclear waste issues, in which public perceptions of human health and environmental risks often differ substantially from scientific consensus about those risks. Public concerns and uncertainties are compounded when scientists from competing groups (government agencies, scientific institutions, industries, and interest groups) make different claims about the likely health and environmental consequences of different policy options. We show the processes by which the public receive and process scientific information about nuclear waste management risks using data taken from interviews with 1800 randomly selected individuals (1200 in New Mexico, and 600 nationwide). Among the more important findings are: (1) members of the public are able to make quite reasonable estimates about what kinds of positions on the risks of nuclear waste disposal will be taken by scientists from differing organizations (e.g. scientists from environmental groups, government agencies, or the nuclear industry); (2) in assessing the credibility of scientific claims, members of the public place great emphasis on the independence of the scientists from those who fund the research; and (3) prior expectations about the positions (or expected biases) of scientists from different organizations substantially affects the ways in which members of the public weigh (and utilize) information that comes from these scientists

  5. Thermal energy storage for industrial waste heat recovery

    Hoffman, H. W.; Kedl, R. J.; Duscha, R. A.

    1978-01-01

    The potential is examined for waste heat recovery and reuse through thermal energy storage in five specific industrial categories: (1) primary aluminum, (2) cement, (3) food processing, (4) paper and pulp, and (5) iron and steel. Preliminary results from Phase 1 feasibility studies suggest energy savings through fossil fuel displacement approaching 0.1 quad/yr in the 1985 period. Early implementation of recovery technologies with minimal development appears likely in the food processing and paper and pulp industries; development of the other three categories, though equally desirable, will probably require a greater investment in time and dollars.

  9. Market forces in municipal and industrial waste-to-energy

    Makansi, J.

    1991-01-01

    The market for municipal and industrial waste-to-energy can be characterized simply as currently soft with continued excellent long-term prospects. But as in all markets large and small, niche opportunities exist now which can be profitable with proper definition and strategy. Economics of several projects have proven marginal, cost overruns are common, and revenue projections are sometimes overstates. Also contributing to poorer economics of late are lower prices for the electric power produced from these plants. New environmental restrictions are adding 10-15% to the capital costs of a given project. On the industrial front, the strength of waste-fuel firing continues to be evident for independent power production. Important fuel-niche markets have sprung up over the last decade including petroleum coke, coal-mining wastes, hospital or redbag wastes, biomass, used tires, and so on. Another fuel niche is hazardous waste incineration. In the municipal arena, realism has not yet hit the recycling and source reduction enthusiasts. Only 25-35% recycling is considered practical by experts. There are also limits to how often material can be recycled. Finally, in spite of the best efforts of the population to control the amount of refuse generated and to recycle that which is, population and economic growth may overtake any new sense of environmental responsibility. And, yes, the additional refuse still has to go somewhere exclamation point The best somewhere option continues to be a waste-to-energy plant. Current market opportunities and two other market forces (international activities and the role of US utilities) are discussed

  10. Selection of melter systems for the DOE/Industrial Center for Waste Vitrification Research

    Bickford, D.F.

    1993-01-01

    The EPA has designated vitrification as the best developed available technology for immobilization of High-Level Nuclear Waste. In a recent federal facilities compliance agreement between the EPA, the State of Washington, and the DOE, the DOE agreed to vitrify all of the Low Level Radioactive Waste resulting from processing of High Level Radioactive Waste stored at the Hanford Site. This is expected to result in the requirement of 100 ton per day Low Level Radioactive Waste melters. Thus, there is increased need for the rapid adaptation of commercial melter equipment to DOE's needs. DOE has needed a facility where commercial pilot scale equipment could be operated on surrogate (non-radioactive) simulations of typical DOE waste streams. The DOE/Industry Center for Vitrification Research (Center) was established in 1992 at the Clemson University Department of Environmental Systems Engineering, Clemson, SC, to address that need. This report discusses some of the characteristics of the melter types selected for installation of the Center. An overall objective of the Center has been to provide the broadest possible treatment capability with the minimum number of melter units. Thus, units have been sought which have broad potential application, and which had construction characteristics which would allow their adaptation to various waste compositions, and various operating conditions, including extreme variations in throughput, and widely differing radiological control requirements. The report discusses waste types suitable for vitrification; technical requirements for the application of vitrification to low level mixed wastes; available melters and systems; and selection of melter systems. An annotated bibliography is included

  12. Cogeneration from poultry industry wastes: Indirectly fired gas turbine application

    Bianchi, M.; Cherubini, F.; De Pascale, A.; Peretto, A.; Elmegaard, B.

    2006-01-01

    The availability of wet biomass as waste from a lot of industrial processes, from agriculture and farms and the need to meet the environmental standards force to investigate all options in order to dispose this waste. The possible treatments usually strongly depend on biomass characteristics, namely water content, density, organic content, heating value, etc. In particular, some of these wastes can be burnt in special plants, using them as energy supply for different processes. The study carried out with this paper is concerned with the promising utilization of the organic wastes from an existing poultry industry as fuel. Different plant configurations have been considered in order to make use of the oil and of the meat and bone meal, which are the by-products of the chicken cooking process. In particular, the process plant can be integrated with an energy supply plant, which can consist of an indirectly fired gas turbine. Moreover, a steam turbine plant or a simplified system for the supply of the only technological steam are investigated and compared. Thermodynamic and economic analysis have been carried out for the examined configurations in order to outline the basic differences in terms of energy savings/production and of return of the investments

    Selchau-Hansen, K; Freyer, K; Treutler, C; Enge, W

    1999-01-01

    Industrial waste was studied concerning its radioactive pollution. Using known properties of the solid state nuclear track detector CR-39 we found among a high concentration of more or less homogeneously distributed single alpha-tracks discrete spots of very high enrichments of alpha-particles created by so called hot particles. We will report about the alpha-activity, the concentration of hot particles and about their ability to be air borne.

  16. Technical and Regulatory Considerations in Using Freight Containers as Industrial Packages

    Hawk, Mark B [ORNL; Opperman, Erich [Washington Savannah River Company; Natali, Ronald [R. B. Natali Consulting, Inc.

    2008-01-01

    The US Department of Energy (DOE), Office of Environmental Management (EM), is actively pursuing activities to reduce the radiological risk and clean up the environmental legacy of the nation's nuclear weapons programmes. The EM has made significant progress in recent years in the clean-up and closure of sites and is also focusing on longer term activities necessary for the completion of the clean-up programme. The packaging and transportation of contaminated demolition debris and low level waste materials in a safe and cost effective manner are essential in completing this mission. Toward this end, the US Department of Transportation's Final Rule on Hazardous Materials Regulation issued on 26 January 2004, included a new provision authorising the use of freight containers (e.g. 20 and 40 ft ISO containers) as industrial packages type 2 or 3. This paper will discuss the technical and regulatory considerations in using these newly authorised and large packages for the packaging and transportation of low level waste materials.

  17. Mixed waste focus area technical baseline report. Volume 2

    1997-04-01

    As part of its overall program, the MWFA uses a national mixed waste data set to develop approaches for treating mixed waste that cannot be treated using existing capabilities at DOE or commercial facilities. The current data set was originally compiled under the auspices of the 1995 Mixed Waste Inventory Report. The data set has been updated over the past two years based on Site Treatment Plan revisions and clarifications provided by individual sites. The current data set is maintained by the MWFA staff and is known as MWFA97. In 1996, the MWFA developed waste groupings, process flow diagrams, and treatment train diagrams to systematically model the treatment of all mixed waste in the DOE complex. The purpose of the modeling process was to identify treatment gaps and corresponding technology development needs for the DOE complex. Each diagram provides the general steps needed to treat a specific type of waste. The NWFA categorized each MWFA97 waste stream by waste group, treatment train, and process flow. Appendices B through F provide the complete listing of waste streams by waste group, treatment train, and process flow. The MWFA97 waste strewn information provided in the appendices is defined in Table A-1

  19. Protein recovery from dairy industry wastes with aerobic biofiltration

    Wheatley, A D; Mitra, R I; Hawkes, H A

    1982-01-01

    Experiments were carried out to improve the economics of effluent treatment by the recovery of single cell protein. Field observations showed that acidic strong wastes, such as those from the dairy industry, produced a predominantly fungal biomass. Mixtures of dairy waste and domestic sewage did not produce fungal films. The most common fungi isolated were Fusarium and Geotrichum, but the species was affected by local conditions, i.e. creamery, yoghurt, milk or cheese wastes and the load to the plant. Batch culture was used to determine the growth requirements of Fusarium and Geotrichum and continuous culture, on vertical and horizontal fixed films, to determine growth and sloughing at different organic loads. The fungi grew well on acidic strong wastes which would discourage other organisms. A 1 cubic metre/hour pilot plant was built to treat the wastes from cheese, butter and cream production. The plant was run at pH 4-5 and at between 5 and 10 kg of BOD/day/cubic metres. BOD removal was between 30 and 50% and biomass production between 0.1 and 0.5 kg of dry solids/day. The filamentous fungal growth was separated from the tower effluent by an inclined screen. The amino acid content of the product was similar to other single-cell protein. Feeding trials are being carried out. (Refs. 14).

  20. High rate composting of herbal pharmaceutical industry solid waste.

    Ali, M; Duba, K S; Kalamdhad, A S; Bhatia, A; Khursheed, A; Kazmi, A A; Ahmed, N

    2012-01-01

    High rate composting studies of hard to degrade herbal wastes were conducted in a 3.5 m(3) capacity rotary drum composter. Studies were spread out in four trials: In trial 1 and 2, one and two turns per day rotation was observed, respectively, by mixing of herbal industry waste with cattle (buffalo) manure at a ratio of 3:1 on wet weight basis. In trial 3 inocula was added in raw waste to enhance the degradation and in trial 4 composting of a mixture of vegetable market waste and herbal waste was conducted at one turn per day. Results demonstrated that the operation of the rotary drum at one turn a day (trial 1) could provide the most conducive composting conditions and co-composting (trial 4) gave better quality compost in terms of temperature, moisture, nitrogen, and Solvita maturity index. In addition a FT-IR study also revealed that trial 1 and trial 4 gave quality compost in terms of stability and maturity due to the presence of more intense peaks in the aromatic region and less intense peaks were found in the aliphatic region compared with trial 2 and trial 3.

  1. Technical issues and solutions on ITER first wall beryllium application. Industrial viewpoint

    Iwadachi, T.; Uda, M.; Ito, M.; Miyakawa, M.; Ibuki, M.

    2004-01-01

    Beryllium is selected as reference armor material of ITER primary first wall and is joined to the copper alloy heat sink such as CuCrZr or Dispersion Strengthened Copper (DSCu) Various joining technologies have been successfully developed and the manufacturing possibilities of large size first wall panels with beryllium armor has been demonstrated. Based on such results, further technical improvement is needed to reduce manufacturing cost and ensure the reliability of joining in actual size first wall. The technical issues to optimize the fabrication process of beryllium attachment were shown in this paper from an industrial point of view. Determination of the optimum size and the surface qualities of beryllium tiles are important issues in term of the material specification to ensure joining reliability and to reduce cost. The consolidation method and the finish machining methods of beryllium tiles are also critical in terms of material cost. These items should be determined by paying concern to the accommodation of the joining methods. The selections of slitting methods for attached beryllium have a great influence on fabrication cost. In the actual fabrication of beryllium attachment, safety provisions for exposure to beryllium in working environment and the recycling of the waste from the fabrication processes will be concerned sufficiently.

    The overall objective of this report is to provide a technical basis to support a U.S. Nuclear Regulatory Commission determination to classify the low-activity waste from the Hanford Site single-shell and double-shell tanks as `incidental` wastes after removal of additional radionuclides and immobilization.The proposed processing method, in addition to the previous radionuclide removal efforts, will remove the largest practical amount of total site radioactivity, attributable to high-level wastes, for disposal in a deep geologic repository. The remainder of the waste would be considered `incidental` waste and could be disposed onsite.

  4. Problems of placement of industrial wastes in landfills in the industrial city

    STEPANOV Evgeniy Georgievich,

    2017-04-01

    Full Text Available The article shows that the anthropogenic transformation of the environment increases when production wastes and consumption are placed in landfills. Hygienic condition of the areas with high population density and developed industry is determined by the increased amount of household and industrial waste, mainly deposited in the numerous landfills. This situation is studied on the example of landfills used for industrial wastes produced by the enterprises JSC «Gazprom Neftekhim Salavat», JSC «Salavatsteklo», located in the city of Salavat of the Republic of Bashkortostan. The sources of industrial pollution in Salavat have been analyzed. One should note that the city-forming enterprise is the JSC «Gazprom Neftekhim Salavat» which share of the total amount of wastes generated in the city per year is 80%. Another company which contributes significantly to this process is the JSC «Salavatsteklo». To study the possible migration of contaminants to the aquifer an observation well has been made at the landfill site. The research of the water obtained from the observation well at the polygon identified maximum allowable concentrations for chemical oxygen demand (COD, phenol and oil products. The groundwater occurrence modes have been studied. The migration of the chemicals contained in the body of the landfill, to groundwater, has been revealed. That leads to contamination of surface water. Laboratory studies of water objects in the zone of influence of industrial waste landfill in Romodanovskomu career have been performed. It was determined that excess of maximum permissible concentration of benzene, and the presence of toluene, lead, phenol indicates the pollution of groundwater by substances stored in landfills Romanovskogo career, both by infiltration and subsequent migration to groundwater of adjacent aquifers and through surface runoff and infiltration from snowmelt and rainwater.

  7. Building world-wide nuclear industry success stories - Safe management of nuclear waste and used nuclear fuel

    Saint-Pierre, S.

    2005-01-01

    Full text: This WNA Position Statement summarizes the worldwide nuclear industry's record, progress and plans in safely managing nuclear waste and used nuclear fuel. The global industry's safe waste management practices cover the entire nuclear fuel-cycle, from the mining of uranium to the long-term disposal of end products from nuclear power reactors. The Statement's aim is to provide, in clear and accurate terms, the nuclear industry's 'story' on a crucially important subject often clouded by misinformation. Inevitably, each country and each company employs a management strategy appropriate to a specific national and technical context. This Position Statement reflects a confident industry consensus that a common dedication to sound practices throughout the nuclear industry worldwide is continuing to enhance an already robust global record of safe management of nuclear waste and used nuclear fuel. This text focuses solely on modern civil programmes of nuclear-electricity generation. It does not deal with the substantial quantities of waste from military or early civil nuclear programmes. These wastes fall into the category of 'legacy activities' and are generally accepted as a responsibility of national governments. The clean-up of wastes resulting from 'legacy activities' should not be confused with the limited volume of end products that are routinely produced and safely managed by today's nuclear energy industry. On the significant subject of 'Decommissioning of Nuclear Facilities', which is integral to modern civil nuclear power programmes, the WNA will offer a separate Position Statement covering the industry's safe management of nuclear waste in this context. The safe management of nuclear waste and used nuclear fuel is a widespread, well-demonstrated reality. This strong safety record reflects a high degree of nuclear industry expertise and of industry responsibility toward the well-being of current and future generations. Accumulating experience and

  9. Norm waste in oil and gas industry: The Syrian experience

    Al-Masri, M.S.; Suman, H.

    2001-01-01

    This paper describes the Syrian experience in respect to Naturally Occurring Radioactive Materials (NORM) waste in Syrian oil and gas industry. NORM can be concentrated and accumulated in tubing and surface equipment of oil and gas production lines in the form of scale and sludge. NORM waste (scale, sludge, production water) is therefore generated during cleaning, physical or chemical treatment of streams. Uncontrolled disposal of this type of waste could lead to environmental pollution, and thus eventually to exposure of members of the public. The presence of NORM in Syrian oil fields has been recognized since 1987 and AECS has initiated several studies, in cooperation with oil companies, to manage such type of waste. Three categories of NORM waste in Syrian oil fields were identified. Firstly, hard scales from either decontamination of contaminated equipment and tubular using high-pressure water systems or mechanical cleaning at site are considered to contain the highest levels of radium isotopes ( 226 Ra, 228 Ra, 224 Ra). Secondly, sludge wastes are generated with large amount but low levels of radium isotopes were found. Thirdly, contaminated soil with 226 Ra as a result of uncontrolled disposal of production water was also considered as NORM waste. The first waste type (scale) is stored in Standard storage barrels in a controlled area; the number of barrels is increasing with time. High levels of radium isotopes were found in these scales. The options for disposal of these wastes are still under investigations; one of the most predominant thinking is the re-injection into abundant wells. For sludge waste, plastic lined disposal pits were constructed in each area for temporary storage. Moreover, big gas power stations have been built and operated since the last ten years. Maintenance operations for these stations produce tens of tones of scales containing radon daughters, 210 Pb and 210 Po with relatively high concentrations. The common practice used to dispose

  11. ASSESSMENT OF TOXICITY OF INDUSTRIAL WASTES USING CROP PLANT ASSAYS

    Carmen Alice Teacă

    2008-11-01

    Full Text Available Environmental pollution has a harmful action on bioresources, including agricultural crops. It is generated through many industrial activities such as mining, coal burning, chemical technology, cement production, pulp and paper industry, etc. The toxicity of different industrial wastes and heavy metals excess was evaluated using crop plant assays (germination and hydroponics seedlings growth tests. Experimental data regarding the germination process of wheat (from two cultivars and rye seeds in the presence of industrial wastes (thermal power station ash, effluents from a pre-bleaching stage performed on a Kraft cellulose – chlorinated lignin products or chlorolignin, along with use of an excess of some heavy metals (Zn and Cu are presented here. Relative seed germination, relative root elongation, and germination index (a factor of relative seed germination and relative root elongation were determined. Relative root elongation and germination index were more sensitive indicators of toxicity than seed germination. The toxic effects were also evaluated in hydroponics experiments, the sensitivity of three crop plant species, namely Triticum aestivum L. (wheat, Secale cereale (rye, and Zea mays (corn being compared. Physiological aspects, evidenced both by visual observation and biometric measurements (mean root, aerial part and plant length, as well as the cellulose and lignin content were examined.

  12. Use of food waste, fish waste and food processing waste for China's aquaculture industry: Needs and challenge.

    Mo, Wing Yin; Man, Yu Bon; Wong, Ming Hung

    2018-02-01

    China's aquaculture industry is growing dramatically in recent years and now accounts for 60.5% of global aquaculture production. Fish protein is expected to play an important role in China's food security. Formulated feed has become the main diet of farmed fish. The species farmed have been diversified, and a large amount of 'trash fish' is directly used as feed or is processed into fishmeal for fish feed. The use of locally available food waste as an alternative protein source for producing fish feed has been suggested as a means of tackling the problem of sourcing safe and sustainable feed. This paper reviews the feasibility of using locally available waste materials, including fish waste, okara and food waste. Although the fishmeal derived from fish waste, okara or food waste is less nutritious than fishmeal from whole fish or soybean meal, most fish species farmed in China, such as tilapia and various Chinese carp, grow well on diets with minimal amounts of fishmeal and 40% digestible carbohydrate. It can be concluded that food waste is suitable as a component of the diet of farmed fish. However, it will be necessary to revise regulations on feed and feed ingredients to facilitate the use of food waste in the manufacture of fish feed. Copyright © 2017 Elsevier B.V.

    As shown at several case studies, waste waters from extinguishing of industrial fires involving hazardous chemicals could be serious threat primary for surrounding environmental compartments (e.g. surface water, underground water, soil) and secondary for human beings, animals and plants. The negative impacts of the fire waters on the environment attracted public attention since the chemical accident in the Sandoz (Schweizerhalle) in November 1986 and this process continues. Last October, special Seminary on this topic has been organized by UNECE in Bonn. Mode of interaction of fire waters with the environment and potential transport mechanisms are still discussed. However, in many cases waste water polluted by extinguishing foam (always with high COD values), flammable or toxic dangerous substances as heavy metals, pesticides or POPs, are released to surface water or soil without proper decontamination, which can lead to environmental accident. For better understanding of this type of hazard and better coordination of firemen brigades and other responders, the ecotoxicity of such type of waste water should be evaluated in both laboratory tests and in water samples collected during real cases of industrial fires. Case studies, theoretical analysis of problem and toxicity tests on laboratory model samples (e.g. on bacteria, mustard seeds, daphnia and fishes) will provide additional necessary information. Preliminary analysis of waters from industrial fires (polymer material storage and galvanic plating facility) in the Czech Republic has already confirmed high toxicity. In first case the toxicity may be attributed to decomposition of burned material and extinguishing foams, in the latter case it can be related to cyanides in original electroplating baths. On the beginning of the year 2012, two years R&D project focused on reduction of extinguish waste water risk for the environment, was approved by Technology Agency of the Czech Republic.

    1996-01-01

    The anaerobic biogasification of organic wastes generates two useful products: a medium-Btu fuel gas and a compost-quality organic residue. Although commercial-scale digestion systems are used to treat municipal sewage wastes, the disposal of solid organic wastes, including municipal solid wastes (MSW), requires a more cost-efficient process. Modern biogasification systems employ high-rate, high-solids fermentation methods to improve process efficiency and reduce capital costs. The design criteria and development stages are discussed. These systems are also compared with conventional low-solids fermentation technology.

    2005-01-01

    China's manufacturing industry is now the 4th largest manufacturing power in the world, second only to the US, Japan, and Germany. Large but not strong, it is still way behind developed countries. In the technical standard field, the gap between China's manufacturing industry and industrially developed countries is showing that there is a low level of technological standards and lack of professional talent versed in technical standards. A technical standards strategy is of importance to the development of China's manufacturing industry has been as one of the major strategies in the 10th Five-Year Plan period. The overall objective of the strategy for China's technical standards should be capable of supporting Chinese enterprises and products in entering the international market and ensuring the superiority of China's key industries in international competition. The implementing tactics of the strategy are all-round tracking, effective adoption, crucial participation, and strong dominance

  4. THE IMPACT OF INDUSTRIAL WASTE LANDFILL ON THE ENVIRONMENT

    Monika Janas

    2017-06-01

    Full Text Available The aim of the study is to assess the environmental impact of a shut down industrial waste landfill. A detailed analysis of the quality of groundwater around the landfill in the years 1995-2016 was conducted. Assessment of the status of groundwater in the landfill area was made based on the results of monitoring tests. It includes the measurement of pH, specific electrical conductivity (SEC and the content of chlorides, sulfates, phosphates, heavy metals: copper (Cu, lead (Pb, chromium (Cr and a number of other pollution indicators. The analysis confirms that the landfill during the operation did not constitute a threat because of a number of employed security measures and sealing layers. Only in recent years, the industrial waste landfill which is already out of operation has become an extremely serious environmental threat. The results of water analyses from the piezometers clearly indicate that there is a problem of groundwater contamination. There was a significant increase in the value of some of the analyzed indicators (such as chlorides and sulfates, mainly in the piezometers located on the flow line of groundwater in the landfill area. The observed situation is probably a result of damage to the sealing layers and leaching of pollutants from waste deposited in the landfill by rain water.

  5. Integration of Cleaner Production and Waste Water Treatment on Tofu Small Industry for Biogas Production using AnSBR Reactor

    Rahayu, Suparni Setyowati; Budiyono; Purwanto

    2018-02-01

    A research on developing a system that integrates clean production and waste water treatment for biogas production in tofu small industry has been conducted. In this research, tofu waste water was turned into biogas using an AnSBR reactor. Mud from the sewage system serves as the inoculums. This research involved: (1) workshop; (2) supervising; (3) technical meeting; (4) network meeting, and (5) technical application. Implementation of clean production integrated with waste water treatment reduced the amount of waste water to be treated in a treatment plant. This means less cost for construction and operation of waste water treatment plants, as inherent limitations associated with such plants like lack of fund, limited area, and technological issues are inevitable. Implementation of clean production prior to waste water treatment reduces pollution figures down to certain levels that limitations in waste water treatment plants can be covered. Results show that biogas in 16 days HRT in an AnSBR reactor contains CH4(78.26 %) and CO2 (20.16 %). Meanwhile, treatments using a conventional bio-digester result in biogas with 72.16 % CH4 and 18.12 % CO2. Hence, biogas efficiency for the AnSBR system is 2.14 times greater than that of a conventional bio-digester.

  6. Biodiesel production using oil from fish canning industry wastes

    Costa, J.F.; Almeida, M.F.; Alvim-Ferraz, M.C.M.; Dias, J.M.

    2013-01-01

    Highlights: • A process was established to produce biodiesel from fish canning industry wastes. • Biodiesel production was enabled by an acid esterification pre-treatment. • Optimization studies showed that the best catalyst concentration was 1 wt.% H 2 SO 4 . • There was no advantage when a two-step alkali transesterification was employed. • Waste oil from olive oil bagasse could be used to improve fuel quality. - Abstract: The present study evaluated biodiesel production using oil extracted from fish canning industry wastes, focusing on pre-treatment and reaction conditions. Experimental planning was conducted to evaluate the influence of acid catalyst concentration (1–3 wt.% H 2 SO 4 ) in the esterification pre-treatment and the amount of methanolic solution (60–90 vol.%) used at the beginning of the further two-step alkali transesterification reaction. The use of a raw-material mixture, including waste oil obtained from olive oil bagasse, was also studied. The results from experimental planning showed that catalyst concentration mostly influenced product yield and quality, the best conditions being 1 wt.% catalyst and 60 vol.% of methanolic solution, to obtain a product yield of 73.9 wt.% and a product purity of 75.5 wt.%. Results from a one-step reaction under the selected conditions showed no advantage of performing a two-step alkali process. Although under the best conditions several of the biodiesel quality parameters were in agreement with standard specifications, a great variation was found in the biodiesel acid value, and oxidation stability and methyl ester content did not comply with biodiesel quality standards. Aiming to improve fuel quality, a mixture containing 80% waste olive oil and 20% of waste fish oil was evaluated. Using such mixture, biodiesel purity increased around 15%, being close to the standard requirements (96.5 wt.%), and the oxidation stability was in agreement with the biodiesel quality standard values (⩾6 h), which

  7. Greater-than-Class C low-level radioactive waste characterization. Appendix E-5: Impact of the 1993 NRC draft Branch Technical Position on concentration averaging of greater-than-Class C low-level radioactive waste

    Tuite, P.; Tuite, K.; Harris, G.

    1994-09-01

    This report evaluates the effects of concentration averaging practices on the disposal of greater-than-Class C low-level radioactive waste (GTCC LLW) generated by the nuclear utility industry and sealed sources. Using estimates of the number of waste components that individually exceed Class C limits, this report calculates the proportion that would be classified as GTCC LLW after applying concentration averaging; this proportion is called the concentration averaging factor. The report uses the guidance outlined in the 1993 Nuclear Regulatory Commission (NRC) draft Branch Technical Position on concentration averaging, as well as waste disposal experience at nuclear utilities, to calculate the concentration averaging factors for nuclear utility wastes. The report uses the 1993 NRC draft Branch Technical Position and the criteria from the Barnwell, South Carolina, LLW disposal site to calculate concentration averaging factors for sealed sources. The report addresses three waste groups: activated metals from light water reactors, process wastes from light-water reactors, and sealed sources. For each waste group, three concentration averaging cases are considered: high, base, and low. The base case, which is the most likely case to occur, assumes using the specific guidance given in the 1993 NRC draft Branch Technical Position on concentration averaging. To project future GTCC LLW generation, each waste category is assigned a concentration averaging factor for the high, base, and low cases

    In the ideal case the liquid waste can safely be disposed of in a properly designed and integrated network of pipes, which collect and transmit the liquid waste into a treatment plant. However, such a system is costly and needs a substantial amount of initial investment to start operating and subsequently to maintain.

  10. Recycled lightweight concrete made from footwear industry waste and CDW.

    Lima, Paulo Roberto Lopes; Leite, Mônica Batista; Santiago, Ediela Quinteiro Ribeiro

    2010-06-01

    In this paper two types of recycled aggregate, originated from construction and demolition waste (CDW) and ethylene vinyl acetate (EVA) waste, were used in the production of concrete. The EVA waste results from cutting off the EVA expanded sheets used to produce insoles and innersoles of shoes in the footwear industry. The goal of this study was to evaluate the influence of the use of these recycled aggregates as replacements of the natural coarse aggregate, upon density, compressive strength, tensile splitting strength and flexural behavior of recycled concrete. The experimental program was developed with three w/c ratios: 0.49, 0.63 and 0.82. Fifteen mixtures were produced with different aggregate substitution rates (0%, 50% EVA, 50% CDW, 25% CDW-25% EVA and 50% CDW-50% EVA), by volume. The results showed that it is possible to use the EVA waste and CDW to produce lightweight concrete having semi-structural properties. Copyright 2010 Elsevier Ltd. All rights reserved.

  11. Influence of non-technical policies on choices of waste solidification technologies

    Trubatch, S.L.

    1987-01-01

    This paper describes and discusses non-technical policy considerations which may improperly influence decisions on the solidification of low-level radioactive wastes (''LLW''). These policy considerations are contained principally in several State and Federal statutes which regulate various aspects of LLW disposal. One policy consideration in particular, the unqualified bias in favor of volume reduction, is shown to present a substantial potential for leading to technically suboptimal decisions on the appropriate processes for solidifying LLW. To avoid the unintended skewing of technical decisions by non-technical policy considerations, certain current policies may need to be revised to ensure that the choices of waste treatment, including decisions on solidification, are based primarily on reasonable assurance of adequate protection of public health and safety. This goal may be realized in part by basing any disposal fee structure on more than just LLW volume to include consideration of the waste's activity and its difficulty of confinement

  6. Socio-technical systems analysis of waste to energy from municipal solid waste in developing economies: a case for Nigeria

    Iyamu Hope O.

    2017-01-01

    Full Text Available Waste generation is an inevitable by-product of human activity, and it is on the rise due to rapid urbanisation, industrialisation, increased wealth and population. The composition of municipal solid waste (MSW in developed and developing economies differ, especially with the organic fraction. Research shows that the food waste stream of MSW in developing countries is over 50%. The case study for this investigation, Nigeria, has minimal formal recycling or resource recovery programs. The average composition of waste from previous research in the country is between 50–70% putrescible and 30–50% non-putrescible, presenting significant resource recovery potential in composting and biogas production. Waste-to-energy (WtE is an important waste management solution that has been successfully implemented and operated in most developed economies. This contribution reports the conditions that would be of interest before WtE potentials of MSW is harnessed, in an efficient waste management process in a developing economy like Nigeria. The investigation presents a set of socio-technical parameters and transition strategy model that would inform a productive MSW management and resource recovery, in which WtE can be part of the solution. This model will find application in the understanding of the interactions between the socio-economic, technical and environmental system, to promote sustainable resource recovery programs in developing economies, among which is WtE.

  14. Evaluation of Technical Efficiency in Indian Sugar Industry: An Application of Full Cumulative Data Envelopment Analysis

    Sunil KUMAR

    2012-05-01

    Full Text Available This study focuses on the inter-temporal and inter-state variations in technical and scale efficiency levels of Indian sugar industry. In the first stage, full cumulative data envelopment analysis (FCDEA is used to derive efficiency scores for 12 major sugar producing states. The panel data truncated regression is employed in the second stage to assess the key factors explaining the observed variations in the efficiency levels. The results suggest that the extent of technical inefficiency in Indian sugar industry is about 35.5 percent per annum, and the observed technical inefficiency stems primarily due to managerial inefficiency rather scale inefficiency. Also, a precipitous decline in the level of technical efficiency has been noticed in the postreforms period relative to the level observed in the pre-reforms period. The availability of skilled labour and profitability have been found to be most significant determinants of technical efficiency in Indian sugar industry.

  17. Risk perception of various technical options in the field of radioactive waste management

    Cameron, F.X.

    1996-01-01

    The author's group had a wide ranging discussion of risk and, at the very end of the discussion got to the question that was posed to them, which is that of risk perception of various technical options in the field of radioactive waste management. Some of the points that were made in this discussion is a reality that the group, as decision-makers, have to deal with, and it has to be treated as a reality. Secondly, the scientist looks at risk from the classic definition of ''probability times consequences'', but the public only looks at the consequences side of the equation, and too often the probability of something happening is treated as a probability of one that it will actually happen. A third problem that was identified in this area is that often the efforts to make the disposal of waste safer may contribute, in the public mind, to the fact that the risk is even more hazardous. And the last problem is that people do not trust what a decision maker is saying when he talks about the fact that there is little probability of something happening. The group then went on to a discussion of how he should try to treat risk perception. One point that was made is that voluntary acceptance of a risk is important. A second point that was made on how to deal with risk perception problems is that the group could try to put the risk of radioactive waste disposal in the perspective of other risks to society, from the chemical industry for instance. The group also talked about the possibility of putting the benefits in perspective for people. Another point was that the group should have different communications strategies for different audiences. But, the more the public is involved in the decision making process, the more comfortable they are going to be with the risk, and the more consistent the perception of risk may be with the scientific definition thereof. In terms of new technologies, new innovations on the generation and management of waste, although these may actually

  19. Disintegration-wave method of recovery of industrial waste iron and steel industry enterprises

    M. A. Vasechkin

    2016-01-01

    Full Text Available Rational use of raw materials and waste is one of the most important factors determining the effectiveness of any processing enterprise. Industrial wastes of mining and metallurgical industries are a valuable source of many elements. However, little activity of the mineral and inconsistent chemical and phase composition of the waste reduce their attractiveness for use as a secondary raw material, and the presence of heavy metals and water-soluble compounds is a serious environmental threat. Fractional excretion of elements that make up the slag can be carried out with the help of their recovery by disintegration-wave method. The paper presents a machine-hardware circuits for the implementation of recovery process of slag and disintegrator design. In conducting research on the example of slag samples of the enterprises in Stavropol and Krasnoyarsk territories, it was found out that the observed enrichment of slags on the composition of iron takes place, its physical and chemical activity increases and persists for a long period of time. These facts were noted in the study of the microstructure and the results of spectral analysis of the initial slags and subjected to recovery by disintegration-wave method. The results analysis led to the conclusion about the possibility of waste recovery of mining and metallurgical industries with by disintegration-wave method. Resulting in the processing materials with enhanced activity of the mineral part and certain chemical and phase composition, can be used as raw material for the production of metallurgical, cement and other industries.

    2008-01-01

    This study aimed to investigate a risk perception about landfill sits for industrial waste or radioactive waste through the questionnaire survey. As a result, it was shown that most of people worried about health and environmental impact of radioactive waste; and moreover, high ratios of the peoples felt dangerous and scary sensuously. Public trust to the central government was very low. Over 60 percent of people do not trust that countermeasures will be taken at the times of accident' and nearly 70 percent of people do not trust that 'the information about the accident is disclosed'. Answers to questions concerning about public trust regarding countermeasures at the accident, information disclosure at the accident, environmental standard, and environmental technology show significant correlation with risk perception of landfill sites.

Producers in every step of this industry, from uranium to reprocessing are working to adapt their products and services both to the more and more competitive conditions of the market and to the utilities evoluting specific needs. For the next decade, the main trend is uranium economy and reduction of industrial costs. For the longer term, the difficult prevision of nuclear energy developments, in particular with new types of reactors necessitates a true capacity of adaptation both from the utilities and from the fuel cycle industry. Cogema has already demonstrated the ability to adapt its industrial capabilities and therefore can prepare confidently for the future challenges [fr

    Mandal, A. K.; Sinha, O. P.

    2018-06-01

    Industrial waste bottom ash (BA) from a pulverized coal combustion boiler containing hard wear-resistant particles was utilized in this study to form an aluminum composite through a liquid metallurgy route. Composites comprising 5 wt.% and 10 wt.% bottom ash were characterized for their physiochemical, microstructural, mechanical, as well as tribological properties, along with pure aluminum. Scanning electron microscopy (SEM) microstructure revealed uniform distribution of BA particles throughout the matrix of the composite, whereas x-ray diffraction (XRD) analysis confirmed presence of aluminosilicate phase. Addition of 10 wt.% BA improved the Brinell hardness number (BHN) from 13 to 19 and ultimate tensile strength (UTS) from 71 MPa to 87 MPa, whereas ductility was adversely reduced after 5% BA addition. Incorporation of BA particles resulted in reduced dry sliding wear rates examined up to 80 N load compared with aluminum. Hence, such composites having lower cost could be applied as significantly hard, wear-resistant materials in applications in the automotive industry.

    2003-05-01

    Chromium being one of the major toxic pollutants is discharged from electroplating and chrome tanning processes and is also found in the effluents of dyes, paint pigments, manufacturing units etc. Chromium exists in aqueous systems in both trivalent (Cr(3+)) and hexavalent (Cr(6+)) forms. The hexavalent form is carcinogenic and toxic to aquatic life, whereas Cr(3+) is however comparatively less toxic. This study was undertaken to investigate the total chromium removal from industrial effluents by chemical means in order to achieve the Pakistan NEQS level of 1 mg/L by the methods of reduction and precipitation. The study was conducted in four phases. In phase I, the optimum pH and cost effective reducing agent among the four popular commercial chemicals was selected. As a result, pH of 2 was found to be most suitable and sodium meta bisulfate was found to be the most cost effective reducing agent respectively. Phase II showed that lower dose of sodium meta bisulfate was sufficient to obtain 100% efficiency in reducing Cr(6+) to Cr(3+), and it was noted that reaction time had no significance in the whole process. A design curve for reduction process was established which can act as a tool for treatment of industrial effluents. Phase III studies indicated the best pH was 8.5 for precipitation of Cr(3+) to chromium hydroxide by using lime. An efficiency of 100% was achievable and a settling time of 30 minutes produced clear effluent. Finally in Phase IV actual waste samples from chrome tanning and electroplating industries, when precipitated at pH of 12 gave 100% efficiency at a settling time of 30 minutes and confined that chemical means of reduction and precipitation is a feasible and viable solution for treating chromium wastes from industries.

  20. Industrial and urban wastes in relation to Cadmium pollution

    Varavipour, M.; Akhondi, M.

    2002-01-01

    Disposal of urban, agricultural and industrial wastes is becoming a major problem in recent times. Ocean dumping, land fill applications and incineration are being considered as unsuitable. so application to agricultural lands is being increasingly used for this purpose. Application of wastes to soils can be beneficial in providing plant nutrients and organic matter. But, it also leads to harmful effects like introduction of heavy metals, toxic organics, danger of ground water pollution, etc. Cadmium buildup in soil and absorption into plants and then entering into food chain due to these wastes is of concern because of its higher mobility than most other heavy metals. Although discontinuation of sewage sludge disposal on crop land would stop further soil contamination, potential danger from metal accumulation by crops grown after termination of the practice is still a concern. Trace metals are relatively immobile in soil. Therefore, depending on biological and chemical equilibria established following terminal sludge application, sludge-borne Cd might change in plant availability with time

  1. Treatment of Municipal and Industrial Waste by Radiation Processing

    Abdelaziz, M.E.

    1999-01-01

    In recent years the effort in science and technology is shifting from conventional technologies preventing the pollution of air, water and soil, towards processing by gamma or by electron beam (EB) irradiation in order to prevent pollution, rather than curing the problems caused by production processes, which are not optimized with regard to pollution control. Radiation processing may help to improve the environmental situation in two aspects : It provides alternatives to conventional technologies for the cleaning of air, flue gases and water,...etc, and it also helps to realize clean processes for preventing pollution in the first place. This paper will outline the basic principles of radiation processing for waste streams of environmental relevance, will summarize the state-of -the-art in environmental applications of radiation processing to show both the advantages and the limitations of the radiation processing of waste streams, and to highlight the environmental and economic benefits of clean processes made possible by radiation processing applied to municipal and industrial waste. Reference is made to gamma and EB radiation sources, and description of new technologies is presented

  2. An Industrial Ecology Approach to Municipal Solid Waste ...

    The organic fraction of municipal solid waste provides abundant opportunities for industrial ecology-based symbiotic use. Energy production, economics, and environmental aspects are analyzed for four alternatives based on different technologies: incineration with energy recovery, gasification, anaerobic digestion, and fermentation. In these cases electricity and ethanol are the products considered, but other products and attempts at symbiosis can be made. The four technologies are in various states of commercial development. To highlight their relative complexities some adjustable parameters which are important for the operability of each process are discussed. While these technologies need to be considered for specific locations and circumstances, generalized economic and environmental information suggests relative comparisons for newly conceptualized processes. The results of industrial ecology-based analysis suggest that anaerobic digestion may improve seven emission categories, while fermentation, gasification, and incineration successively improve fewer emissions. A conceptual level analysis indicates that gasification, anaerobic digestion, and fermentation alternatives lead to positive economic results. In each case the alternatives and their assumptions need further analysis for any particular community. Presents information useful for analyzing the sustainability of alternatives for the management of municipal solid waste.

  11. TECHNICAL AND REGULATORY CONSIDERATIONS IN USING FREIGHT CONTAINERS AS INDUSTRIAL PACKAGES

    Opperman, E; Mark Hawk, M; Ron Natali, R

    2007-10-16

    The United States (US) Department of Energy (DOE), Office of Environmental Management (EM), is actively pursuing activities to reduce the radiological risk and clean up the environmental legacy of the nation's nuclear weapons programs. EM has made significant progress in recent years in the clean-up and closure of sites and is also focusing on longer-term activities necessary for the completion of the clean-up program. The packaging and transportation of contaminated demolition debris and low-level waste (LLW) materials in a safe and cost-effective manner are essential in completing this mission. Toward this end, the US Department of Transportation's (DOT) Final Rule on Hazardous Materials Regulation Final Rule issued January 26, 2004, included a new provision authorizing the use of Freight Containers (e.g., 20 and 40-foot ISO Containers) as Industrial Packages Type 1, 2, or 3 (IP-1, IP-2, and IP-3). This paper will discuss the technical and regulatory considerations in using these newly authorized and large packages for the packaging and transportation of LLW materials.

    2018-01-01

    Waste biomass from agro-food industries are a reliable and readily exploitable resource. From the circular economy point of view, direct residues from these industries exploited for production of fuel/chemicals is a winning issue, because it reduces the environmental/cost impact and improves the eco-sustainability of productions. The present paper reports recent results of deep eutectic solvent (DES) pretreatment on a selected group of the agro-industrial food wastes (AFWs) produced in Europe. In particular, apple residues, potato peels, coffee silverskin, and brewer's spent grains were pretreated with two DESs, (choline chloride-glycerol and choline chloride-ethylene glycol) for fermentable sugar production. Pretreated biomass was enzymatic digested by commercial enzymes to produce fermentable sugars. Operating conditions of the DES pretreatment were changed in wide intervals. The solid to solvent ratio ranged between 1:8 and 1:32, and the temperature between 60 and 150 °C. The DES reaction time was set at 3 h. Optimal operating conditions were: 3 h pretreatment with choline chloride-glycerol at 1:16 biomass to solvent ratio and 115 °C. Moreover, to assess the expected European amount of fermentable sugars from the investigated AFWs, a market analysis was carried out. The overall sugar production was about 217 kt yr -1 , whose main fraction was from the hydrolysis of BSGs pretreated with choline chloride-glycerol DES at the optimal conditions. The reported results boost deep investigation on lignocellulosic biomass using DES. This investigated new class of solvents is easy to prepare, biodegradable and cheaper than ionic liquid. Moreover, they reported good results in terms of sugars' release at mild operating conditions (time, temperature and pressure).

    Highlights: ► We model magnetic energy conversion machine for the use of industrial waste heat. ► Efficiencies and masses of the system are evaluated by a numerical model. ► Excellent potential of profitability is expected with large low-exergy heat sources. -- Abstract: The main objective of this theoretical study was to investigate under which conditions a magnetic energy conversion device (MECD) – utilizing industrial waste heat – is economically feasible. Furthermore, it was evaluated if magnetic energy conversion (MCE) has the potential of being a serious concurrent to already existing conventional energy conversion technologies. Up-today the availability of magnetocaloric materials with a high Curie temperature and a high magnetocaloric effect is rather limited. Therefore, this study was mainly focused on applications with heat sources of low to medium temperature levels. Magnetic energy conversion machines, containing permanent magnets, are numerically investigated for operation conditions with different temperature levels, defined by industrial waste heat sources and environmental heat sinks, different magnetic field intensities and different frequencies of operation (number of thermodynamic cycles per unit of time). Theoretical modeling and numerical simulations were performed in order to determine thermodynamic efficiencies and the exergy efficiencies as function of different operation conditions. From extracted data of our numerical results, approximate values of the total mass and total volume of magnetic energy conversion machines could be determined.

  4. Preliminary technical data summary for the Defense Waste Processing Facility, Stage 1

    1980-09-01

    This Preliminary Technical Data Summary presents the technical basis for design of Stage 1 of the Staged Defense Waste Processing Facility (DWPF), a process to efficiently immobilize the radionuclides in Savannah River Plant (SRP) high-level liquid waste. The radionuclides in SRP waste are present in sludge that has settled to the bottom of waste storage tanks and in crystallized salt and salt solution (supernate). Stage 1 of the DWPF receives washed, aluminum dissolved sludge from the waste tank farms and immobilizes it in a borosilicate glass matrix. The supernate is retained in the waste tank farms until completion of Stage 2 of the DWPF at which time it filtered and decontaminated by ion exchange in the Stage 2 facility. The decontaminated supernate is concentrated by evaporation and mixed with cement for burial. The radioactivity removed from the supernate is fixed in borosilicate glass along with the sludge. This document gives flowsheets, material, and curie balances, material and curie balance bases, and other technical data for design of the Stage 1 DWPF

  5. Content of nitrogen in waste petroleum carbon for steel industries

    Rios, R.O; Jimenez, A.F; Szieber, C.W; Banchik, A.D

    2004-01-01

    Steel industries use refined carbon as an alloy for steel production. This alloy is produced from waste carbon from the distillation of the petroleum. The refined carbon, called recarburizer, is obtained by calcination at high temperature. Under these thermal conditions the organic molecules decompose and a fraction of the N 2 , S and H 2 , volatile material and moisture are released; while the carbon tends to develop a crystalline structure similar to graphite's. The right combination of calcinations temperature and time in the furnace can optimize the quality of the resulting product. The content of S and N 2 has to be minimized for the use of calcined carbon in the steel industry. Nitrogen content should be reduced by two orders of magnitude, from 1% - 2% down to hundreds of ppm by weight. This work describes the activities undertaken to obtain calcined coke from petroleum from crude oil carbon that satisfies the requirements of the Mercosur standard 02:00-169 (Pending) for use as a carborizer in steels industries. To satisfy the requirements of the Mercosur standards NM 236:00 IRAM-IAS-NM so that graphite is used as a carburizer a content of 300 ppm maximum weight of nitrogen has to be obtained. So the first stage in this development is to define a production process for supplying calcined coke in the range of nitrogen concentrations required by the Mercosur standards (CW)

    Full Text Available The main purpose of the study is to depict the evolution of technical museums across Romania, high-lighting a new trend - visible in the past few years - towards preservation of industrial heritage assets in areas that have undergone functional reorganization. This trend is the result of the country's adaptation to the new socio-economic conditions, but also an accession into the stage of cultural and touristic capitalization on industrial heritage assets, acting as a support-activity in boosting the economy of dis advantaged industrial areas. The second purpose of the study consists of elaborating a critical analysis of technical museums from Romania in order to identify the characteristics to use to increase their cultural role. Also, the analysis is focused on the premise to make technical museums stand out as tourist attraction hubs and to preview their role in the redevelopment of industrial areas in decline, banking on a positive economic and socio-cultural impact.

  8. Brick industry: Technical and economic assessment of energy saving measures

    Florio, G.; Romeo, G. (Calabria Univ., Arcavacata di Rende (Italy). Dipt. di Meccanica)

    Starting from a detailed energy analysis of the production cycle of bricks, the authors make a technical and economic assessment of any possible measure aimed at rationalizing energy. They take energy conservation into consideration not only through the use of exhausted oil residues, but also through the employment of a turboalternator or an internal combustion engine for cogeneration. Both applications of cogeneration prove to be highly interesting from an economic viewpoint even though the turboalternator is put at a disadvantage in competing with internal combustion engines since it increases the overall cogeneration plant costs with respect to the latter.

  10. Bio-electrochemical system (BES) as an innovative approach for sustainable waste management in petroleum industry.

    Srikanth, Sandipam; Kumar, Manoj; Puri, S K

    2018-02-15

    Petroleum industry is one of the largest and fast growing industries due to the ever increasing global energy demands. Petroleum refinery produces huge quantities of wastes like oily sludge, wastewater, volatile organic compounds, waste catalyst, heavy metals, etc., because of its high capacity and continuous operation of many units. Major challenge to this industry is to manage the huge quantities of waste generated from different processes due to the complexity of waste as well as changing stringent environmental regulations. To decrease the energy loss for treatment and also to conserve the energy stored in the chemical bonds of these waste organics, bio-electrochemical system (BES) may be an efficient tool that reduce the economics of waste disposal by transforming the waste into energy pool. The present review discusses about the feasibility of using BES as a potential option for harnessing energy from different waste generated from petroleum refineries. Copyright © 2018.

  11. The technical challenge of mechanized excavation for nuclear waste repositories

    Smith, A.I.

    1991-01-01

    This paper presents the historical background of the tunnel boring machine and discusses its integration into the design of a nuclear waste repository. It is essential that the designers of a project utilize the productivity of the system to their advantage. An example would be the construction of a pair of small tunnels instead of a single large diameter access ramp. The pair of tunnels would be more effective in use and less expensive to bore than the single all-purpose tunnel. The designers of an underground nuclear waste repository must recognize the capabilities of the Tunnel Boring Machine system and tailor their design to employ the technological advantages which have been made in recent years

  13. Playing on strengths : technical innovations keep Canadian industry on top

    Harvie, W.

    1997-01-01

    The Western Canada Sedimentary Basin is one of Canada's major petroleum regions. Some fields in the region have been in production for 80 years. Since most of the major discoveries have been made, the challenge today is to use new technologies to find smaller reservoirs and to extract as much oil as possible from the depleting reserves. The following technical innovations were developed by Canadian companies for enhanced oil recovery: (1) steam assisted gravity drainage for heavy oil, (2) horizontal drilling, (3) coiled tube drilling, (4) single well steam assisted gravity drainage, (5) hydrocyclone technology in which briny water is sent down the borehole for reinjection and in which centrifugal force sends the lighter oil to the middle of the hydrocyclone where it is collected, and (6) portable top drives aimed at newer versions of large land drilling rigs and offshore operations. Multi-lateral techniques have also been used to increase production on heavy oil properties. These and other technical innovations are recognized as the single best advantage that Canadians have to offer the global marketplace. 4 figs

  14. Analysis of waste treatment requirements for DOE mixed wastes: Technical basis

    1995-02-01

    The risks and costs of managing DOE wastes are a direct function of the total quantities of 3wastes that are handled at each step of the management process. As part of the analysis of the management of DOE low-level mixed wastes (LLMW), a reference scheme has been developed for the treatment of these wastes to meet EPA criteria. The treatment analysis in a limited form was also applied to one option for treatment of transuranic wastes. The treatment requirements in all cases analyzed are based on a reference flowsheet which provides high level treatment trains for all LLMW. This report explains the background and basis for that treatment scheme. Reference waste stream chemical compositions and physical properties including densities were established for each stream in the data base. These compositions are used to define the expected behavior for wastes as they pass through the treatment train. Each EPA RCRA waste code was reviewed, the properties, chemical composition, or characteristics which are of importance to waste behavior in treatment were designated. Properties that dictate treatment requirements were then used to develop the treatment trains and identify the unit operations that would be included in these trains. A table was prepared showing a correlation of the waste physical matrix and the waste treatment requirements as a guide to the treatment analysis. The analysis of waste treatment loads is done by assigning wastes to treatment steps which would achieve RCRA compliant treatment. These correlation's allow one to examine the treatment requirements in a condensed manner and to see that all wastes and contaminant sets are fully considered

  15. Use of some industrial waste as energy storage media

    Tayeb, A.M.

    1996-01-01

    Solar energy is stored using different solid storage materials, both chemical and metallic industrial wastes. The materials tested in the present study are paraffin wax, copper slag, aluminium slag, iron slag, cast iron slag and copper chips. Solar energy is stored in these materials and energy ia then recovered with water stream at different flow rates and the storage capacity and period for different materials were compared. The same set of experiments is run on solid metallic materials mixed with wax. The results indicated that iron slag has the highest storage capacity followed by cast iron slag then aluminium slag and copper chips and copper slag. It is also noted that addition of paraffin wax to the solid metallic material improves its storage capacity and duration greatly. The storage efficiency of different units is calculated and compared. 5 figs

  16. Radiation Protection and the Management of Radioactive Waste in the Oil and Gas Industry

    2010-01-01

    The oil and gas industry, a global industry operating in many Member States, makes extensive use of radiation generators and sealed and unsealed radioactive sources, some of which are potentially dangerous to human health and the environment if not properly controlled. In addition, significant quantities of naturally occurring radioactive material (NORM) originating from the reservoir rock are encountered during production, maintenance and decommissioning. The oil and gas industry operates in all climates and environments, including the most arduous conditions, and is continuously challenged to achieve high efficiency of operation while maintaining a high standard of safety and control - this includes the need to maintain control over occupational exposures to radiation, as well as to protect the public and the environment through proper management of wastes that may be radiologically and chemically hazardous. The oil and gas industry is organizationally and technically complex, and relies heavily on specialized service and supply companies to provide the necessary equipment and expertise, including expertise in radiation safety. This training manual is used by the IAEA as the basis for delivering its training course on radiation protection and the management of radioactive waste in the oil and gas industry. Enclosed with this manual is a CD-ROM that contains the presentational material used in the training course, the course syllabus and additional notes for course presenters.

    2012-01-01

    One of the main basic fields of economy in Tajikistan is mining industry. Its development in the past lead to accumulation of huge amount of wastes basically from uranium reprocessing enterprises, containing radionuclides in anthropogenic highly concentrations (basically uranium-thorium chain) and other harmful substances. They are located in zones very close to residential as well as in upper course of water inflow of such main rivers of the region as Amudarya and Syrdarya. Sulphates, heavy metals, cyanides and others (basically with water flow) released to the environment besides uranium reprocessing wastes and other mining enterprises. This makes it necessary to restore in the region the complex coordinated monitoring programs with the purpose of their actual assessment and potential impact on environment as well as priority justification of possible remediation measures. One of the important are balance assessment and trans-boundary radionuclide re-deposition of uranium-thorium chain and other toxic elements in Syrdarya and Amudarya rivers with the purpose of regional formation character revealing of radiation and other ecological risks for saving the normal vital activity in the region.

  7. EMISSION AND TRENDS IN RECLAIMING WASTE HEAT IN INDUSTRIAL INSTALATIONS

    Lech Hys

    2013-04-01

    Full Text Available The article presents the analysis of waste heat emission in a typical industrial installation. On the basis of the process monitoring system, periodic analyses of fumes composition, installation process manual and the conducted measurements of the heat fluxes from individual sources emitting heat on the way of natural convection from the devices’ coats and forced convection in the fumes flux were calculated. According to the authors the heat of temperature 140–155 °C and surface power density 860–970 W/m2 emitted by devices’ covers can be reclaimed in ORC techniques, Peltier’s modules and the systems realising Stirling cycle. Part of the waste heat included in fumes, which makes c.a. 76% of the total emission from the installation, should be returned to the process of fuel oxidation, what will reduce the emission by c.a. 18% and the volume of consumed fuel by c.a. 25 m3 CH4/h, according to the presented calculations.

  8. Waste to Wealth: Hidden Treasures in the Oil Palm Industry

    Loh Soh Kheang; Astimar Abdul Aziz; Ravigadevi Sambathamurthi; Mohd Basri Wahid

    2010-01-01

    The palm oil industry plays an important role in the creation of waste to wealth using the abundant oil palm biomass resources generated from palm oil supply chain i.e. upstream to downstream activities. The oil palm biomass and other palm-derived waste streams available are oil palm trunks (felled), fronds (felled and pruned), shell, mesocarp fibers, empty fruit bunches (EFB), palm oil mill effluent (POME), palm kernel expelled (PKE), palm fatty acid distillates (PFAD), used frying oil (UFO), residual oil from spent bleaching earth (SBE) and glycerol. For 88.5 million tonnes of fresh fruit bunches (FFB) processed in 2008, the amount of oil palm biomass generated was more than 25 million tones (dry weight basis) with the generation of 59 million tonnes of POME from 410 palm oil mills. Oil palm biomass consists of mainly lignocellulose materials that can be potentially and fully utilized for renewable energy, wood-based products and high value-added products such as pytonutrients, phenolics, carotenes and vitamin E. Oil palm biomass can be converted to bio energy with high combustible characteristics such as briquettes, bio-oils, bio-producer gas, boiler fuel, biogas and bio ethanol. Oil palm biomass can also be made into wood-based products such as composite and furniture, pulp and paper and planting medium. The recovery of phenolics from POME as valuable antioxidants has potential drug application. Other possible applications for oil palm biomass include fine chemicals, dietary fibers, animal feed and polymers. There must be a strategic and sustainable resource management to distribute palm oil and palm biomass to maximize the use of the resources so that it can generate revenues, bring benefits to the palm oil industry and meet stringent sustainability requirements in the future.

  9. Regional analysis of potential energy production from agricultural wastes: technical and economic study. Final report

    Have, H

    1981-01-01

    The possibilities for utilization of agricultural wastes for energy production are analyzed in two Danish counties, Ringkoebing and Vestsjaelland, which have different agricultural production patterns. The quantitative analysis shows that the major waste products, surplus straw, waste wood and animal waste, in total with present technique can cover about 28% of the demand for heat energy (mostly space heating) in both counties. The potential coverage from straw, wood and animal waste is about 3, 3 and 22% in Ringkoebing and 18, 2 and 8% in Vestsjaelland respectively. A technical analysis indicates that direct combustion is the most favorable conversion method for straw and wood while biological conversion at present is best suited for animal waste. An economic analysis based on costs of collection, storage, transport and conversion of wastes and costs of corresponding oil and oil conversion were made. From a community point of view only straw and wood are found to be competitive to the expensive gas fuel oil when burned in automatically stoked furnaces. From a heating station point of view waste utilization is more attractive because of the sales tax on oil products. Here straw and wood are competitive fuels to both gas and heavy fuel oil in all the analyzed systems except from the small manually stoked furnaces. Animal waste seems to be competitive only when replacing gas fuel oil in medium size (500 kW) well utilized aerobic fermenters.

    Serres, Christophe; Rocher, Muriel [Institut de Radioprotection et de Surete Nucleaire (IRSN), Fontenay-aux-Roses (France); Bernier, Frederic [FANC, Brussels (Belgium); Havlova, Vaclava [UJV Rez, a.s., Rez (Czech Republic); Mrskova, Adela [DECOM A.S., Trnava (Slovakia); Dubreuil, Gilles Heriard [MUTADIS, Paris (France)

    2013-07-01

    SITEX is a 24 months FP7 Euratom project (from January 2012 to December 2013) led by IRSN and bringing together organisations representing technical safety organisations and nuclear safety authorities performing technical and scientific assessment of geological disposals for radioactive waste in the framework of their respective national regulatory review process of the safety case. Civil society outreach specialists of interaction with civil society are also involved in the project. SITEX aims at establishing the conditions required for developing sustainable interactions among experts from various horizons (nuclear safety authorities, technical safety organisations, civil society organisations..) capable of developing and coordinating joint and harmonized activities in relation with the safety assessment of the safety case. Among foreseen activities, partnership with the civil society experts is considered as a key function of the future network in order to contribute in enhancing trust in the decision making process. The SITEX program of work is split into a set of six workpackages that address technical and organizational issues allowing in fine to propose a structure of the activities and operating modes of the future network. These issues relate on the one hand to the study of the potential for sharing and developing technical expertise practices independently from the expertise developed by waste management organisations, on the other hand on the ability to implement coordinated R and D programs run by technical safety organisations in order to develop the scientific knowledge necessary to perform technical assessments.

  12. Management of NORM/TENORM Waste from Non Nuclear Industries

    Djarot S Wisnubroto

    2003-01-01

    Management of NORM/TENORM waste is now to be an issue and discussed in many international conferences and seminars. This paper describes the status of the management of NORM/TENORM waste including the origin of the waste, regulations and assessment of waste disposal. Several countries have established the regulation for NORM/TENORM waste; however the IAEA has not yet published guideline for management of NORM/TENORM. There are many options for disposal of NORM/TENORM waste based on standard of the radioactive waste disposal. The decision and policy on management of NORM/TENORM waste must be conducted carefully due to the social and economical impacts. (author)

  13. Treatment methods for radioactive mixed wastes in commercial low-level wastes - technical considerations

    MacKenzie, D.R.; Kempf, C.R.

    1986-01-01

    Treatment options for the management of three generic categories of radioactive mixed waste in commercial low-level wastes (LLW) have been identified and evaluated. These wastes were characterized as part of a BNL study in which LLW generators were surveyed for information on potential chemical hazards in their wastes. The general treatment options available for mixed wastes are destruction, immobilization, and reclamation. Solidification, absorption, incineration, acid digestion, wet-air oxidation, distillation, liquid-liquid solvent extraction, and specific chemical destruction techniques have been considered for organic liquid wastes. Containment, segregation, decontamination, and solidification or containment of residues, have been considered for lead metal wastes which have themselves been contaminated and are not used for purposes of waste disposal shielding, packaging, or containment. For chromium-containing wastes, solidification, incineration, wet-air oxidation, acid digestion, and containment have been considered. Fore each of these wastes, the management option evaluation has included an assessment of testing appropriate to determine the effect of the option on both the radiological and potential chemical hazards present

  16. Mixed Waste Focus Area integrated technical baseline report, Phase 1: Volume 1

    1996-01-01

    The Department of Energy (DOE) established the Mixed Waste Characterization, Treatment, and Disposal Focus Area (MWFA) to develop and facilitate implementation of technologies required to meet the Department's commitments for treatment of mixed low-level and transuranic wastes. The mission of the MWFA is to provide acceptable treatment systems, developed in partnership with users and with participation of stakeholders, tribal governments, and regulators, that are capable of treating DOE's mixed waste. These treatment systems include all necessary steps such as characterization, pretreatment, and disposal. To accomplish this mission, a technical baseline is being established that forms the basis for determining which technology development activities will be supported by the MWFA. The technical baseline is the prioritized list of deficiencies, and the resulting technology development activities needed to overcome these deficiencies. This document presents Phase I of the technical baseline development process, which resulted in the prioritized list of deficiencies that the MWFA will address. A summary of the data and the assumptions upon which this work was based is included, as well as information concerning the DOE Office of Environmental Management (EM) mixed waste technology development needs. The next phase in the technical baseline development process, Phase II, will result in the identification of technology development activities that will be conducted through the MWFA to resolve the identified deficiencies

  20. Strategy of Construction and Demolition Waste Management after Chemical Industry Facilities Removal

    Tashkinova, I. N.; Batrakova, G. M.; Vaisman, Ya I.

    2017-06-01

    Mixed waste products are generated in the process of irrelevant industrial projects’ removal if conventional techniques of their demolition and dismantling are applied. In Russia the number of unused chemical industry facilities including structures with high rate of wear is growing. In removing industrial buildings and production shops it is used conventional techniques of demolition and dismantling in the process of which mixed waste products are generated. The presence of hazardous chemicals in these wastes makes difficulties for their use and leads to the increasing volume of unutilized residues. In the process of chemical industry facilities’ removal this fact takes on special significance as a high level of hazardous chemicals in the waste composition demands for the realization of unprofitable measures aimed at ensuring environmental and industrial safety. The proposed strategy of managing waste originated from the demolition and dismantling of chemical industry facilities is based on the methodology of industrial metabolism which allows identifying separate material flows of recycled, harmful and ballast components, performing separate collection of components during removal and taking necessary preventive measures. This strategy has been tested on the aniline synthesis plant being in the process of removal. As a result, a flow of 10 wt. %, subjected to decontamination, was isolated from the total volume of construction and demolition waste (C&D waste). The considered approach allowed using the resource potential of more than 80wt. % of waste and minimizing the disposed waste volume.

  5. A technical basis for meeting waste form stability requirements of 10 CFR 61

    Chang, W.Y.; Skoski, L.; Eng, R.; Tuite, P.T.

    1988-01-01

    To assure that solidified low level waste forms meet the stability requirements of 10 CFR 61 regulations, the US Nuclear Regulatory Commission (NRC) has published Branch Technical Positions (BTPs) and draft Regulatory Guide on waste form stability. These guidance documents describe the test procedures and acceptance criteria for six stability parameters: leachability, compressive strength, immersion effect, radiation effect, thermal stability and biodegradability. The most recent set of recommended tests and acceptance criteria are presented in the November 1986 Preliminary Draft Regulatory Guide Low Level Waste Form Stability. The objective of this study was to: (1) investigate the regulatory and technical bases for the required stability tests, (2) evaluate the relevance of these tests and acceptance criteria based on actual test results, and (3) recommended alternatives to the testing and acceptance criteria. The latter two objectives are discussed in this paper

  6. The conceptual design of waste repository for radioactive waste from medical, industrial and research facilities containing comparatively high radioactivity

    Yamamoto, Masayuki; Hashimoto, Naro

    2002-02-01

    Advisory Committee on Nuclear Fuel Cycle Backend Policy reported the basic approach to the RI and Institute etc. wastes on March 2002. According to it, radioactive waste form medical, industrial and research facilities should be classified by their radioactivity properties and physical and chemical properties, and should be disposed in the appropriate types of repository with that classification. For the radioactive waste containing comparatively high radioactivity generated from reactors, NSC has established the Concentration limit for disposal. NSC is now discussing about the limit for the radioactive waste from medical, industrial and research facilities containing comparatively high radioactivity. Japan Nuclear Cycle Development Institute (JNC) preliminary studied about the repository for radioactive waste from medical, industrial and research facilities and discussed about the problems for design on H12. This study was started to consider those problems, and to develop the conceptual design of the repository for radioactive waste from medical, industrial and research facilities. Safety assessment for that repository is also performed. The result of this study showed that radioactive waste from medical, industrial and research facilities of high activity should be disposed in the repository that has higher performance of barrier system comparing with the vault type near surface facility. If the conditions of the natural barrier and the engineering barrier are clearer, optimization of the design will be possible. (author)

Issues addressed in the study include the factors that trigger waste diversion activities by ICI establishments, barriers to the initiation of waste diversion practices, and the social aspects of waste reduction/recycling/reuse practices.

  10. Technical training of indigenous people for resource industry jobs

    Millbank, G. [Praxis Technical Group, Vancouver, BC (Canada)

    2001-07-01

    The economic, moral and legal arguments for employing local indigenous people for resource extraction jobs are discussed. In addition to explaining the 'why' for training, similar arguments are developed for the 'when' , 'where', and 'how' aspects of training, stressing the superior qualities of DeepLearning(TM), a method developed by the Praxis Technical Group, which embodies many aspects of teaching and learning technologies utilized in indigenous communities around the world. In this training technology the most intense teaching is said to occur during the performance of rites and ceremonies, common to indigenous cultures. While the emphasis in all rituals may appear to be focused entirely upon deities or ancestors, careful observation reveals that there is also a hidden emphasis on creating an appropriate, receptive state of mind among the participants in the ritual. DeepLearning(TM) makes use of this technique by making the learner relaxed, focused and receptive before presenting examples of optimal behaviour. The style of learning is individual, unstressed, free of distractions, and claimed to be many times more effective than typical classroom sessions.

  11. Radiation and applications: Technical innovation made by industrial irradiation procedures

    Wiesner, L.

    1986-01-01

    The innovation represented by irradiation as a means of industrial process technology lies in the very special way in which energy is introduced into some object in which it initiates reactions. This is based on the penetrating capability of ionizing radiation, which can produce reactive species, especially radicals, inside an object without requiring the whole object to be subjected to such conditions as, e.g., high temperatures or pressures, which would otherwise be needed to initiate the corresponding reactions. This unique advantage of triggering off reactions by means of ionizing radiation results in possibilities of process technology no other procedure can offer. An aspect becoming more and more important is the possibility to replace expensive materials hard to process by cheaper materials brought into a specific form more easily. Irradiation processes can assign to these materials at least some of the properties and combinations of properties, respectively, of higher-grade materials. (orig.) [de

  17. Final environmental assessment: TRU waste drum staging building, Technical Area 55, Los Alamos National Laboratory

    1996-01-01

    Much of the US Department of Energy's (DOE's) research on plutonium metallurgy and plutonium processing is performed at Los Alamos National Laboratory (LANL), in Los Alamos, New Mexico. LANL's main facility for plutonium research is the Plutonium Facility, also referred to as Technical Area 55 (TA-55). The main laboratory building for plutonium work within the Plutonium Facility (TA-55) is the Plutonium Facility Building 4, or PF-4. This Environmental Assessment (EA) analyzes the potential environmental effects that would be expected to occur if DOE were to stage sealed containers of transuranic (TRU) and TRU mixed waste in a support building at the Plutonium Facility (TA-55) that is adjacent to PF-4. At present, the waste containers are staged in the basement of PF-4. The proposed project is to convert an existing support structure (Building 185), a prefabricated metal building on a concrete foundation, and operate it as a temporary staging facility for sealed containers of solid TRU and TRU mixed waste. The TRU and TRU mixed wastes would be contained in sealed 55-gallon drums and standard waste boxes as they await approval to be transported to TA-54. The containers would then be transported to a longer term TRU waste storage area at TA-54. The TRU wastes are generated from plutonium operations carried out in PF-4. The drum staging building would also be used to store and prepare for use new, empty TRU waste containers

  1. Technical performance characterization of fourier transform profilometry for quantitative waste volume determination under Hanford waste tank conditions - 16281

    Monts, David L.; Jang, Ping-Rey; Long, Zhiling; Norton, Olin P.; Gresham, Lawrence L.; Su, Yi; Lindner, Jeffrey S.

    2009-01-01

    The Hanford Site in western Washington state is currently in the process of an extensive effort to empty and close its radioactive single-shell and double-shell waste storage tanks. Before this can be accomplished, it is necessary to know how much residual material is left in a given waste tank and the chemical makeup of the residue. The Institute for Clean Energy Technology (ICET) at Mississippi State University is currently developing an quantitative in-tank inspection system based on Fourier Transform Profilometry, FTP. FTP is a non-contact, 3-D shape measurement technique. By projecting a fringe pattern onto a target surface and observing its deformation due to surface irregularities from a different view angle, FTP is capable of determining the height (depth) distribution (and hence volume distribution) of the target surface, thus reproducing the profile of the target accurately under a wide variety of conditions. Hence FTP has the potential to be utilized for quantitative determination of residual wastes within Hanford waste tanks. We report the results of a technical feasibility study to document the accuracy and precision of quantitative volume determination using the Fourier transform profilometry technique under simulated Hanford waste tank conditions. We have initiated a technical feasibility assessment of the Fourier transform profilometry (FTP) technique for determining the volume of residual waste in Hanford radioactive waste tanks; preliminary results to date are presented in this paper. We find that we achieve FTP volume determinations with relatively small errors under conditions corresponding to the most challenging within a Hanford waste tank-viewing non-descript targets at a distance of 16.1 m (53 ft) and an angle of 62 deg.. We have determined that we can minimize measurement uncertainty by maximizing the camera-to-projector distance d, using an optical zoom of at least 5x, and ensuring that FTP images are only recorded after instrumental warm

    This project addresses both the technical and economic feasibility of replacing industrial gas in lime kilns with synthesis gas from the gasification of hog fuel. The technical assessment includes a materials evaluation, processing equipment needs, and suitability of the heat content of the synthesis gas as a replacement for industrial gas. The economic assessment includes estimations for capital, construction, operating, maintenance, and management costs for the reference plant. To perform these assessments, detailed models of the gasification and lime kiln processes were developed using Aspen Plus. The material and energy balance outputs from the Aspen Plus model were used as inputs to both the material and economic evaluations.

    El-Sebaie, O; Ahmed, M; Ramadan, M

    2000-01-01

    The aim of this study is to stabilize and solidify two different treated industrial hazardous waste sludges, which were selected from factories situated close to Alexandria. They were selected to ensure their safe transportation and landfill disposal by reducing their potential leaching of hazardous elements, which represent significant threat to the environment, especially the quality of underground water. The selected waste sludges have been characterized. Ordinary Portland Cement (OPC), Cement Kiln Dust (CKD) from Alexandria Portland Cement Company, and Calcium Sulphate as a by-product from the dye industry were used as potential solidification additives to treat the selected treated waste sludges from tanning and dyes industry. Waste sludges as well as the solidified wastes have been leach-tested, using the General Acid Neutralization Capacity (GANC) procedure. Concentration of concerning metals in the leachates was determined to assess changes in the mobility of major contaminants. The treated tannery waste sludge has an acid neutralization capacity much higher than that of the treated dyes waste sludge. Experiment results demonstrated the industrial waste sludge solidification mix designs, and presented the reduction of contaminant leaching from two types of waste sludges. The main advantages of solidification are that it is simple and low cost processing which includes readily available low cost solidification additives that will convert industrial hazardous waste sludges into inert materials.

  6. Identifying industrial best practices for the waste minimization of low-level radioactive materials

    Levin, V.

    1996-04-01

    In US DOE, changing circumstances are affecting the management and disposal of solid, low-level radioactive waste (LLW). From 1977 to 1991, the nuclear power industry achieved major reductions in solid waste disposal, and DOE is interested in applying those practices to reduce solid waste at DOE facilities. Project focus was to identify and document commercial nuclear industry best practices for radiological control programs supporting routine operations, outages, and decontamination and decommissioning activities. The project team (DOE facility and nuclear power industry representatives) defined a Work Control Process Model, collected nuclear power industry Best Practices, and made recommendations to minimize LLW at DOE facilities.

    The Pars Special Economic Energy Zone (PSEEZ) is located in the south of Iran, on the northern coastline of the Persian Gulf. This area was established in 1998 for the utilization of south Pars field oil and gas resources. This field is one of the largest gas resources in the world and contains about 6% of the total fossil fuels known. Petrochemical industries, gas refineries and downstream industries are being constructed in this area. At present there are three gas refineries in operation and five more gas refineries are under construction. In this study, different types of solid waste including municipal solid waste (MSW) and industrial wastes were investigated separately. The aim of the study was to focus on the management of the industrial wastes in order to minimize the environmental impact. In the first stage, the types and amounts of industrial waste in PSEEZ were evaluated by an inventory. The main types of industrial waste are oil products (fuel oil, light oil, lubricating oil), spent catalysts, adsorbents, resins, coke, wax and packaging materials. The waste management of PSEEZ is quite complex because of the different types of industry and the diversity of industrial residues. In some cases recycling/reuse of waste is the best option, but treatment and disposal are also necessary tools. Recently a design has been prepared for a disposal site in PSEEZ for the industrial waste that cannot be reused or recycled. The total surface area of this disposal site where the industrial waste should be tipped for the next 20 years was estimated to be about 42 000 m2.

    Currently, there is increasing competition for waste as feedstock for the growing number of biogas plants. This has led to fluctuation in feedstock supply and biogas plants being operated below maximum capacity. The feasibility of supplementing a protein/lipid-rich industrial waste (pig manure, slaughterhouse waste, food processing and poultry waste) mesophilic anaerobic digester with carbohydrate-rich energy crops (hemp, maize and triticale) was therefore studied in laboratory scale batch and continuous stirred tank reactors (CSTR) with a view to scale-up to a commercial biogas process. Co-digesting industrial waste and crops led to significant improvement in methane yield per ton of feedstock and carbon-to-nitrogen ratio as compared to digestion of the industrial waste alone. Biogas production from crops in combination with industrial waste also avoids the need for micronutrients normally required in crop digestion. The batch co-digestion methane yields were used to predict co-digestion methane yield in full scale operation. This was done based on the ratio of methane yields observed for laboratory batch and CSTR experiments compared to full scale CSTR digestion of industrial waste. The economy of crop-based biogas production is limited under Swedish conditions; therefore, adding crops to existing industrial waste digestion could be a viable alternative to ensure a constant/reliable supply of feedstock to the anaerobic digester.

  9. Construction and operation of an industrial solid waste landfill at Portsmouth Gaseous Diffusion Plant, Piketon, Ohio

    NONE

    1995-10-01

    The US Department of Energy (DOE), Office of Waste Management, proposes to construct and operate a solid waste landfill within the boundary of the Portsmouth Gaseous Diffusion Plant (PORTS), Piketon, Ohio. The purpose of the proposed action is to provide PORTS with additional landfill capacity for non-hazardous and asbestos wastes. The proposed action is needed to support continued operation of PORTS, which generates non-hazardous wastes on a daily basis and asbestos wastes intermittently. Three alternatives are evaluated in this environmental assessment (EA): the proposed action (construction and operation of the X-737 landfill), no-action, and offsite shipment of industrial solid wastes for disposal.

    Andreola, F.

    2005-12-01

    Full Text Available The ongoing accumulation of industrial waste speaks to the need to seek cost-effective disposal methods. Brick manufacture would appear to be particularly promising in this regard. The present study analyzes the possibility of recycling the sludge generated in porcelain tile polishing, as well as coal, steel and municipal incinerator ash to make a special type of facing brick whose properties readily accommodate a full analysis of all the problems deriving from the incorporation of residue in its manufacture. Physical-chemical, mechanical and structural analyses were performed on bricks made with varying percentages of the different types of waste considered. This first paper reports the results of the physical arid technological characterization of the products; the second part of the research will address their chemical, mechanical and structural properties.

  12. Legal and technical problems in the management of radioactive waste from the nuclear power cycle

    Charlesworth, F.R.; Driscoll, J.A.

    1977-01-01

    Nuclear power generation like all other industrial activities results in the production of wastes, the principal difference between radioactive wastes and other wastes being that it is at present impossible to dispose of significant quantities of the former in the environment. However, the possibility of their disposal without having to control them remains a long-term objective and numerous countries are pursuing detailed scientific research on the subject. In the meantime storage and control in a manner appropriate to their nature and aimed at preventing all accidental dispersal to the environment is the only solution. (NEA) [fr

    The Hanford Site is currently in the process of an extensive effort to empty and close its radioactive single-shell and double-shell waste storage tanks. Before this can be accomplished, it is necessary to know how much residual material is left in a given waste tank and the chemical makeup of the residue. The Institute for Clean Energy Technology (ICET) at Mississippi State University is currently developing a quantitative in-tank inspection system based on Fourier Transform Profilometry (FTP). FTP is a non-contact, 3-D shape measurement technique. By projecting a fringe pattern onto a target surface and observing its deformation due to surface irregularities from a different view angle, FTP is capable of determining the height (depth) distribution (and hence volume distribution) of the target surface, thus reproducing the profile of the target accurately under a wide variety of conditions. Hence FTP has the potential to be utilized for quantitative determination of residual wastes within Hanford waste tanks. We report the results of a technical feasibility study to document the accuracy and precision of quantitative volume determination using the Fourier transform profilometry technique under simulated Hanford waste tank conditions.

    Ulsido, Mihret D; Li, Meng

    2016-07-01

    The financial and social contributions of coffee processing industries within most coffee export-based national economies like Ethiopia are generally high. The type and amount of waste produced and the waste management options adopted by these industries can have negative effects on the environment. This study investigated the solid waste management options adopted in wet coffee processing industries in the Gidabo watershed of Ethiopia. A field observation and assessment were made to identify whether the operational characteristics of the industries have any effect on the waste management options that were practiced. The investigation was conducted on 125 wet coffee processing industries about their solid waste handling techniques. Focus group discussion, structured questionnaires, key informant interview and transect walks are some of the tools employed during the investigation. Two major types of wastes, namely hull-bean-pulp blended solid waste and wastewater rich in dissolved and suspended solids were generated in the industries. Wet mills, on average, released 20.69% green coffee bean, 18.58% water and 60.74% pulp by weight. Even though these wastes are rich in organic matter and recyclables; the most favoured solid waste management options in the watershed were disposal (50.4%) and industrial or household composting (49.6%). Laxity and impulsive decision are the driving motives behind solid waste management in Gidabo watershed. Therefore, to reduce possible contamination of the environment, wastes generated during the processing of red coffee cherries, such as coffee wet mill solid wastes, should be handled properly and effectively through maximisation of their benefits with minimised losses. © The Author(s) 2016.

    Claes, J.; Menon, S.

    2001-01-01

    The OECD Nuclear Energy Agency's Co-operative Programme on Decommissioning was established in 1985 to share the experience and information emerging from on-going decommissioning projects within member countries. The main aim of the programme is to gather and collate such data, which can then provide the basis for planning the future industrial phase of decommissioning of commercial nuclear plants. Starting with 10 decommissioning projects in 1985, today the programme has 35 participating projects from 12 countries. Apart from exchanging valuable information, task groups have been set up for in-depth analysis and studies of areas of common interest, among which are the recycling of material from decommissioning projects and decommissioning costs. This paper will describe the structure and mode of operation of the programme. Some of the results of the work in the task groups will be presented, with particular emphasis on the management of materials from decommissioning and on decommissioning costs. (author)

    Japan Atomic Energy Agency (JAEA) is supposed to draw up the plan for the disposal program of the very low-level radioactive waste and low-level radioactive waste generated from medical, industrial and research facilities. For instance, there are these facilities in JAEA, universities, private companies, and so on. JAEA has to get to know about the waste and its acceptance of other institutions described above because it is important for us to hold the licenses for the disposal program regarding safety assessment. This report presents the basic data concerning radioactive waste of research institutes etc. except RI waste, domestic and foreign information related to acceptance criteria for disposal of the low-level radioactive waste, the current status of foreign medical waste management, waste acceptance, and such. In this report, Japan's acceptance criteria were summarized on the basis of present regulation. And, the criteria of foreign countries, United States, France, United Kingdom and Spain, were investigated by survey of each reference. In addition, it was reported that the amount of waste from laboratories etc. for near-surface disposal and their characterization in our country. The Subjects of future work: the treatment of hazardous waste, the problem of the double-regulation (the Nuclear Reactor Regulation Law and the Law Concerning Prevention from Radiation Hazards due to Radioisotopes and Others) and the possession of waste were discussed here.

    Resmi, N G; Fasila, K A

    2017-10-01

    This paper proposes a novel algorithm for establishing a standard methodology to manage and refurbish e-waste called E-waste Management And Refurbishment Prediction (EMARP), which can be adapted by refurbishing industries in order to improve their performance. Waste management, particularly, e-waste management is a serious issue nowadays. Computerization has been into waste management in different ways. Much of the computerization has happened in planning the waste collection, recycling and disposal process and also managing documents and reports related to waste management. This paper proposes a computerized model to make predictions for e-waste refurbishment. All possibilities for reusing the common components among the collected e-waste samples are predicted, thus minimizing the wastage. Simulation of the model has been done to analyse the accuracy in the predictions made by the system. The model can be scaled to accommodate the real-world scenario. Copyright © 2017 Elsevier Ltd.

    Hydrothermal liquefaction (HTL) is a viable thermochemical process for converting wet solid wastes into biocrude which can be hydroprocessed to liquid transportation fuel blendstocks and specialty chemicals. The aqueous byproduct from HTL contains significant amounts (20 to 50%) of the feed carbon, which must be used to enhance economic sustainability of the process on an industrial scale. In this study, aqueous fractions produced from HTL of industrial and municipal waste were characterized using a wide variety of analytical approaches. Organic chemical compounds present in these aqueous fractions were identified using two-dimensional gas chromatography equipped with time-of-flight mass spectrometry. Identified compounds include organic acids, nitrogen compounds, alcohols, aldehydes, and ketones. Conventional gas chromatography and liquid chromatography methods were employed to quantify the identified compounds. Inorganic species, in the aqueous stream of hydrothermal liquefaction of these aqueous byproducts, also were quantified using ion chromatography and inductively coupled plasma optical emission spectroscopy. The concentrations of organic chemical compounds and inorganic species are reported, and the significance of these results is discussed in detail.

  19. Production of Enzymes From Agricultural Wastes and Their Potential Industrial Applications.

    Bharathiraja, S; Suriya, J; Krishnan, M; Manivasagan, P; Kim, S-K

    Enzymatic hydrolysis is the significant technique for the conversion of agricultural wastes into valuable products. Agroindustrial wastes such as rice bran, wheat bran, wheat straw, sugarcane bagasse, and corncob are cheapest and plentifully available natural carbon sources for the production of industrially important enzymes. Innumerable enzymes that have numerous applications in industrial processes for food, drug, textile, and dye use have been produced from different types of microorganisms from agricultural wastes. Utilization of agricultural wastes offers great potential for reducing the production cost and increasing the use of enzymes for industrial purposes. This chapter focuses on economic production of actinobacterial enzymes from agricultural wastes to make a better alternative for utilization of biomass generated in million tons as waste annually. © 2017 Elsevier Inc.

  20. Optimisation of industrial wastes reuse as construction materials.

    Collivignarelli, C; Sorlini, S

    2001-12-01

    This study concerns the reuse of two inorganic wastes, foundry residues and fly ashes from municipal solid waste incineration, as "recycled aggregate" in concrete production. This kind of reuse was optimised by waste treatment with the following steps: waste washing with water; waste stabilisation-solidification treatment with inorganic reagents; final grinding of the stabilised waste after curing for about 10-20 days. Both the treated wastes were reused in concrete production with different mix-designs. Concrete specimens were characterised by means of conventional physical-mechanical tests (compression, elasticity modulus, shrinkage) and different leaching tests. Experimental results showed that a good structural and environmental quality of "recycled concrete" is due both to a correct waste treatment and to a correct mix-design for concrete mixture.
