Life cycle assessment as a tool for controlling the development of technical activities: application to the remediation of a site contaminated by sulfur

摘要: Abstract The objective of this study is to show how a life cycle assessment approach can be used direct the development technical activities according environmental considerations. case deals with remediation soil contaminated by sulfur in an industrial context. merits four treatment techniques are compared taking into account raw materials and energy consumption, air water emissions waste production. First results discussed criterion criterion. It shown that bio-leaching most energy-consuming technique, whereas liming requires highest quantity materials. Furthermore, related atmospheric highlight importance transportation operations balance especially offsite landfilling. As regards production, may divided two groups: on one hand, onsite containment which lead great quantities stored onsite, other landfilling for transported out site. Then, multicriteria analysis enables aggregate inventory results, avoiding compensation phenomena. Based analysis, appears environmentally-friendly result important burdens.
