Um novo estilo de vida, com mudancas nos padroes de consumo e de geracao de residuos, se impoe para humanidade. No Brasil, o crescimento das cidades e, ao mesmo tempo, o aumento de consumo de produtos industrializados, sao fatores comuns a praticamente todos os municipios. Deste modo, graves problemas tem sido acarretados, no que diz respeito a gestao inadequada dos residuos solidos urbanos (RSU) gerados. Em funcao do seu grande numero, os municipios de pequeno porte contribuem com os problemas ambientais e sociais decorrentes. Assim, uma das principais medidas a serem tomadas para corrigir esta situacao e o estabelecimento de Planos da Gestao dos RSU (PGRSU) gerados em tais municipios. O presente trabalho levantou alguns conceitos e modelos de gestao e gerenciamento de RSU, visando fornecer orientacoes para elaboracao de PGRSU para municipios de pequeno porte, embasados nos conceitos de minimizacao. Os municipios de pequeno porte podem contar com algumas facilidades no que diz respeito a uma gestao mais integrada dos diferentes residuos, em especial a comunicacao com a populacao, a fiscalizacao das medidas propostas, a organizacao da sociedade no processo gestao dos RSU. Alem disto, a quantidade de residuos gerados e menor e os processos de segregacao, coleta e disposicao podem ser mais simplificados. Por outro lado, tais municipios enfrentam dificuldades para a implantacao de uma boa gestao dos RSU, entre elas a falta de recursos financeiros e humanos. Levando em conta tais caracteristicas, foram sistematizadas algumas diretrizes e estabelecidos alguns procedimentos que melhor se adaptem aos referidos municipios, contemplando solucoes simplificadas, de baixo custo, acessiveis a tecnicos e administradores sem especializacao no tema e que envolva a populacao. Tais orientacoes foram aplicadas a um caso especifico de municipio de pequeno porte (Itamogi-MG). Como produto final, foi elaborado um PGRSU, incorporando caracteristicas locais previamente identificadas, tanto de ordem geral como relativas aos RS. A metodologia empregada nesta elaboracao mostrou-se adequada para definir uma gestao dos RSU que atenda as necessidades e limitacoes desses municipios.

O objetivo principal do projeto e desenvolver e realizar um programa de capacitacao em saneamento ambiental, em carater piloto, com uma visao multidisciplinar e integrada dos sistemas de abastecimento de agua, sistemas de esgotamento sanitario, manejo integrado de residuos solidos e drenagem de agua pluviais urbanas com enfase na operacao destes sistemas.

This research was developed by considering that the solid waste produced in the process of pig iron production represents the loss of raw materials and the increase in environmental problem. The charcoal based mini blast-furnace off gases dust named CHARCOK was collected from SIDERPA - Siderurgica Paulino Ltda, located in Sete Lagoas, Minas Gerais. The Charcok was characterized and classified according to ABNT (Associa?

The Clean Water Act (CWA) was passed in response to increased pollution in the nation's navigable waters caused by industrial actors and others. Congress sought to achieve two goals with the CWA: eliminate pollution discharges into the nation's waters, and achieve national uniformity in a water pollution control scheme. However, Congress recognized that complete elimination of all pollution discharges was not immediately achievable. As a result, it created a dual-permitting scheme under the CWA, authorizing the Environmental Protection Agency (EPA) to issue permits for the discharge of pollutants into navigable waters, and the U.S. Army Corps of Engineers (Corps) to issue permits for the discharge of dredged or fill material into navigable waters. The 2009 Supreme Court decision in Coeur Alaska, Inc. v. Southeast Alaska Conservation Council reveals that the line separating the EPA's and the Corps' respective permitting authority has become blurred. In this case, the Court upheld the Corps' issuance of a fill permit to a gold mining project seeking to discharge mining waste into a nearby lake. The Court held that the Corps, and not the EPA, possesses the authority to issue permits for the discharge of fill material, regardless of whether the fill is also considered a pollutant under the CWA. Additionally, the Court held that the strict EPA-promulgated effluent discharge limitations for new sources of discharge do not apply to Corps permits. The Court's opinion threatens to undermine the two goals of the CWA because it opens the door for industrial actors to circumvent the stricter EPA permit requirements by simply ensuring their waste disposal contains a sufficient amount of fill.

This paper quantitatively assesses the influence of a new accounting system for liability provisions. According to the analysis results, the new accounting system was able to estimate more accurate amounts of the radwaste's costs than that of previous accounting systems. Removing a steep increase of liability provisions over time recognized acquisition costs of the related assets. For example, it was identified that the transferred decommissioning costs were able to decrease 52% in 2040 because the new accounting system recognized great costs earlier in time when compared to the outdated version of the accounting system. Additionally, in order to secure a radwaste's fund for NPPs, the Korean Radwaste Management Act was legislated in 2007 thanks to government efforts. This Act has been a cornerstone in the levy and operation of the radwaste fund with cash liquidity. © 2010 Elsevier Ltd. All rights reserved.

Electronic waste legislation is non-uniform, at both the national and global level, and a variety of financial and collection schemes exist [1, 2]. In some locations, e-waste stakeholders have preempted mandatory take-back by creating heir own e-waste programs. Whether involved by mandate or voluntarily, stakeholders would like to develop strategies that minimize their financial burden. However, the economic performance of an e-waste recovery system is affected by collection and market uncertainties. Thus, to ensure system success, stakeholders must first understand the impact of uncertainty on economic performance.

Electronic waste, or e-waste, is defined as discarded or obsolete electronic devices such as computers. E-waste presents a challenge to domestic and global waste infrastructure because of its large quantities, short product life, and decreasing product size [1]-[3]. These changes are due to constantly changing product characteristics and rapid technological innovation. E-waste is known to contain valuable materials such as gold and copper, which can generate revenue from recycling e-waste and recovering materials. State of the art recycling technologies available to recover materials from e-waste

Municipal solid waste management is a complex and multidisciplinary problem, involving a number of impact factors associated with various uncertainties. In this study, a hybrid interval-parameter possibilistic programming (IPP) approach was developed and applied for planning municipal solid waste management under dual uncertainties. The IPP improves upon the existing management approaches by allowing possibility distributions of the lower and upper bounds of some interval parameters in the objective function and interval information in the modelling coefficients to be effectively incorporated within its optimization. By introducing the concept of possibilistic interval numbers, the dual uncertainties can be communicated into the optimization process and the resulting solutions, such that the generated decision schemes can effectively reflect the highly complex system features under uncertainty. The results of the case study indicate that useful information can be obtained for providing feasible decision schemes for waste flow allocation. Different decision schemes can be generated by adjusting waste flow allocation patterns within the solution intervals. Lower decision variable values should be used to obtain lower system cost of waste treatment and disposal under advantageous conditions, and higher decision variable values should be used under demanding conditions (worst case conditions). A strong desire to acquire the lower system cost will lead to the decreased probability of meeting the treatment and disposal requirements (i.e. the increased risk of unforeseen conditions)

The Environmental Protection Agency (EPA) published its 'Proposed Rule for Disposal of Coal Combustion Residuals (CCRs) from Electric Utilities' in the June 21, 2010, Federal Register (FR). The proposed rule is driven by several failures of surface impoundments for fly ash, increasing petitions from citizen and environmental groups requesting that EPA develop rules related to CCR management, and new information on human and ecological risks and health effects related to CCRs. The EPA is proposing to specifically regulate CCRs under the Resource Conservation and Recovery Act (RCRA) for the first time. EPA also determined that beneficial uses of these CCRs posed no significant risk. The proposed rule calls for public comment on two approaches available under RCRA for addressing the perceived risks of CCRs. Under this proposal, CCRs from electric utilities and destined for disposal would be managed as a special waste and would be subject to existing Subtitle C regulations under 40 CFR 260-268, 270-272.

The current state of RLIS (Reverse Logistics Information System) for e-waste (Electronic Waste) reverse logistics is no integrated and effective reverse logistics information system for disposing e-waste information of management. When Social needs, the time is a system to produce. We draw up an information system model for e-waste reverse logistics based on internet to solve the lack of RLIS. Next, it introduces the main technique in detail and puts forward design scheme of e-waste reverse logistics RLIS based on internet. Especially it used the GIS technique. It is a multifactor model to analyze e-waste material flow. It has great significance for the visualization of e-waste logistics, management dynamically real time and assistance decision analysis. © 2010 IEEE.

Background and purpose: European Community claims for end-of-vehicles (ELVs) targets of at least 85% recycling and 95% recovery rate by 2015. At present, only about 80% of ELV total weight is being recycled, whereas the remaining fraction of 20%, which is called automotive shredder residue (ASR), is disposed by landfilling in most of the EU countries. In this study a comparison has been carried out among five ASR management strategies, chosen after a screening of the most common technologies suitable and available nowadays, aiming at proposing alternatives to the current disposal in terms of benefits resulting from the conservation of nonrenewable resources and reduction of wastes disposal. These scenarios are ASR landfill disposal, the current status quo for a further nonferrous metals recovery, ASR incineration with energy recovery, an advanced material recovery followed by thermal treatment of ASR residue and a feedstock recycling by means of gasification. Methods: Life Cycle Assessment (LCA) methodology was applied in order to characterise and quantify the environmental impacts related to each scenario analysed, using the SimaPro 7.1 software and the Eco-indicator'99 method, according to a hierarchic approach. Results and discussion: The analysis shows that recovering nonferrous metals ensures a reduction of the environmental loads related to resources depletion due to landfill disposal, but no significant benefit for human health end point can be observed. The ASR thermal treatment in incinerators allows both the decrease of impacts due to plastic fraction disposal and benefits from energy recovery, but a decrease of ecosystem quality occurs because of stack emissions. A net environmental performance upgrading seems to be ensured by those scenarios which include the application of post-shredder technologies. Conclusions: Industrial processes aimed to matter recovery, after shredding, resulted not only in a necessary solution to fit the European recovery and recycling targets for ELVs but also to the options that can obtain greater environmental benefits compared to present practises. However, further improvement can be achieved only by integrating end-of-life treatments into Eco-design strategies aiming at a more efficient separation of high value-added materials such as plastics and metals. © 2010 Springer-Verlag.

Cleaner production plays an important role in minimizing the consumption of water, raw materials, energy, and the generation of waste during industrial processes. Tax breaks, equipment subsidies and penalties are often considered the main policy tools for promoting enterprises to adopt cleaner production technologies, especially in Chinese electroplating industry. However, the results of these policies implementation are confronting with some uncertainty because of the conflicts of the interest between players involved. This paper presents a framework for analyzing the conflicts between a local government and a potentially polluting firm by using game theory. We enriched the model by adding policy variables, such as psychological costs (m), environmental benefit evaluation (E), and reward local government for its implementation (R), to change the payoffs, which can improve the current policies. Using theoretical and numerical analysis, the effects of subsidies, penalties and other policy variables on implementation of cleaner production were obtained. © 2010 Elsevier B.V.

Medical waste is potentially dangerous since it may contain pathogenic agents. As a result, medical waste management requires that institutions take decisions, and implement a wide range of measures in order to reduce health risks. In this respect, many European countries have enacted legislation and good practice guidelines to define, classify, and treat medical waste. In reference to Spain, even though no specific national law has as yet been passed to regulate medical waste management, 13 of its regional governments have adopted regulations concerning medical waste management to guarantee health and environment protection. This paper presents the results of a study of the regional legislation in Spain. In our research, certain differences were detected regarding the criteria used for sorting, collection, storage, transport, treatment, and disposal practices. It was found that these differences in waste management criteria could have health implications as well as environmental and economic consequences, both inside and outside healthcare installations. The paper also proposes a set of general criteria upon which medical waste management should be based. Effective medical waste management should include the following: (i) a clear definition of medical waste and of the scope of legislation concerning it

The first reports of NORM associated with mineral oil & natural gases appeared in 1904. The occurrence of helium in natural gas and its radiogenic origins was observed and exploited during the 1920's. Later reports describe the occurrence of radium in reservoir water from oil & gas fields since the 1930's. In the 1970's & 1980's several observations prompted renewed interest. Radioactive Scale Formation was presented to the RSC in Manchester and the OTC in 1985. Published in JPT June 1987, it has taken 20 years for these papers to be fully recognized as seminal Artigos by the international oil & gas industry. The lessons learned by the international oil & gas industry, health & safety professionals and health physicists over the last 20 years from these seminal papers must be clearly understood and applied today. The original multi-disciplinary applied research work has facilitated a practical and knowledgeable way forward for the oil & gas industry, the regulators, academia and the public (SRS 34, Radiation Protection and Management of Radioactive Waste in the Oil & Gas Industry, IAEA, 2003) An October 2008 Louisiana Court highlighted that the JPT June 1987 paper contributed to the body of scientific literature by demonstrating the first correlation between gamma ray well logging units in API and conventional health physics radiological dose units. Prior to this health & safety professionals in the oil & gas industry had not recognized any potential topside health concerns due to radioactive scale in tubulars based upon API units in well logging Artigos etc. This paper will show that the new challenges arising during decommissioning and with radioactive waste may be addressed through a combination of current best practice and innovative thinking provided we remember the lessons to be learnt and progress over the last century (IAEA 2008).
