Análise crítica da aplicação da avaliação do ciclo de vida no contexto de remediação de áreas contaminadas

Abstract:

The remediation of contaminated areas is the application of technique (s) in a contaminated area, aiming at the removal, containment or reduction of contaminant concentrations. The remediation processes may result in environmental impacts associated with resource use, emissions and transformation of the area. In such contest since 1999 emerged studies to assess the environmental impacts associated with remediation processes. From a systematic literature review, this paper presents the application of the international review of life cycle in remediation technology and evaluates considering the method presented in the ISO 14040 series. The functional unit and temporal scope varied depending on the scenario of contamination and the technical criteria established for remediation. Most of the studies were prospective and attributional approach. For assessing the impact of the life cycle, the studies utilized methodologies midpoint of impact, and the impact category of the potential incidence of overall heating. Some authors consider impacts beyond the remediation process, the impacts related to the contamination, distinguishing them as primary and secondary, respectively. The main difficulty reported in the studies evaluated was the absence of specific data, such as cultures of microorganisms and iron nanoparticles
