“…The present study makes an innovative contribution by classifying a large number of sustainability considerations and establishing structural relationships among stakeholder influence, institutional forces, and sustainable practices [21]. Decision support tools (DST) such as multi-criteria decision analysis (MCDA) have been recognized to play a vital and challenging role in the remediation of contaminated sites [22][23][24][25]. MCDA is an activity that helps making decisions mainly in terms of choosing, ranking or sorting the actions, and the primary goal of research in MCDA is to develop tools to help people to make more reasonable decisions [26].…”

Abstract:Under the circumstances of limited government funds, the future pollution remediation policies and practical implementation may need contemplation from the perspective of maximized efficacy, in order to pursue the most effective resource allocation. In fact, different pollution sources and types affect the value of surrounding properties differently in significance and scope. Therefore, benefits from the remediation may vary depending on the polluted locations. Currently, however, decision-making on the location-based priority of pollution remediation still seems to be in need of a clear index system to evaluate the post-remediation benefits. Therefore, this article discusses the use of the fuzzy Delphi method to determine factors of the location-based priority of soil and groundwater pollution remediation and an analytic network process to determine the weights of each factor. The empirical results show that the top 3 priority indicators are resident population, land value and natural resources. Hopefully, this finding can be used in future decision-making on the priority of pollution remediation to maximize the effect of limited funds.

“…De uma abordagem centrada em custo em meados da década de 1970, tornou-se uma abordagem de estudos de viabilidade tecnológica em meados da década de 1980, seguida de uma abordagem baseada em risco em meados da década de 1990. Por sua vez, a partir de 2000 observa-se que as decisões ambientais devem ser socialmente robustas, em um contexto de desenvolvimento sustentável (Pollard et al, 2004).…”

RESUMOA remediação de áreas contaminadas é a aplicação de técnica(s) visando à remoção, redução ou contenção de contaminantes. Os processos de remediação podem acarretar impactos ambientais associados ao uso de recursos, emissões e transformação da área. Este artigo apresenta o levantamento do estado da arte referente ao uso da ACV aplicada a tecnologias de remediação, bem como o contexto de remediação de áreas contaminadas no Brasil. Esta pesquisa foi conduzida com base em uma revisão bibliográfica sistemática. Os critérios envolveram o estabelecimento de palavras-chave para a busca de informações, a definição dos meios e plataformas de busca (bases de dados), bem como classificação e sistematização. O levantamento de dados procedeu-se até o mês de dezembro de 2011. Trinta e sete estudos foram localizados, entre 1997 e 2011. Destes, trinta artigos indexados em periódicos científicos internacionais e sete de outros fontes. A unidade funcional e o escopo temporal variaram, dependendo do cenário da contaminação e dos critérios técnicos estabelecidos para a remediação. Para a avaliação do impacto do ciclo de vida, a maior parte dos estudos utilizou metodologias de impacto de ponto médio, sendo que a categoria de impacto de maior incidência foi o potencial de aquecimento global. A aplicação da ACV nos estudos de casos pesquisados foi considerada um método que permitiu mapear os impactos ambientais associados às tecnologias de remediação, apesar de limitações quanto aos inventários e a complexidade dos processos.

LIFE CYCLE ASSESSMENT (LCA) APPLIED TO REMEDIATION TECHNOLOGIES ABSTRACTThe remediation of contaminated areas requires the application of techniques to remove, reduce, or contain contaminants. The processes of remediation can result in environmental impacts associated with resource use, emissions, and transformation of the area. This article presents a survey of the technique of using LCA to map remediation technologies, as well as the context of remediation of contaminated areas in Brazil. The research was carried out based on a systematic literature review. The criteria involved the establishment of keywords to search for information, definition of media, and search platforms (databases), as well as classification and systematization. Data were collected until December 2011. Thirty-seven published studies were located, mainly in journals, between 1997 and 2011. The functional units of time and scope varied depending on the scenario of contamination and the technical criteria established for the remediation. To evaluate the impact of the life cycle, most of the studies used midpoint impact methodologies. The global warming potential was the impact category with the highest incidence of midpoints. The application of LCA in the case studies surveyed was considered a method that allowed mapping of the environmental impacts associated with remediation technologies, even considering the existing limitations of th...

When evaluating remediation technologies for contaminated soil and groundwater, the beneficial effect of the remediation, namely cleaner soil and groundwater, are mostly emphasized without consideration of the environmental impact of the remediation activities themselves. Nevertheless, practitioners and decision makers can rely on a broad range of decision tools that can help them to achieve a better balance between economic, social and environmental health aspects of contaminated land remediation. A holistic approach for the management of contaminated land should ideally include an assessment of the environmental risk of the contamination, an assessment of the environmental, social and health impact of the remediation process and a cost-benefit analysis of the remediation project.A life cycle framework, including a life cycle management (LCM) approach structuring environmental activities and life cycle analysis (LCA) for a quantitative examination, can be helpful for the selection of site remediation options with minimum impact on the ecosystem and human health. During the last 10 years, several instances have emerged in which a life cycle approach has been applied to the remediation of contaminated sites. Besides addressing the environmental impact of the remediation activities for a specific site, attention should also be paid to the consequence of reintroducing a remediate site into the economy. From a legal point of view, there should be ways to encourage the use of sustainable remediation technologies, together with a disconnection of treated soils from the definition of waste. Finally, the focus should move from remediation, whether sustainable or not, to the prevention of soil contamination..
