LIFE CYCLE ASSESSMENT AND WASTE MANAGEMENT –LESSONS FOR INDUSTRY AND POLICY MAKERS
Life-cycle assessment (LCA) is a method for evaluating the potential environmental impacts of a product or service from “cradle to grave, i.e. from extraction of raw material, production, use and waste handling. During the last decades, LCA has been applied to waste management in a number of studies. The aim of this paper is to analyse what industry and policymakers can learn from these studies on a general level. Among the findings of relevance here are: ·The waste hierarchy stating the environmental preference of recycling over incineration with energy recovery, over landfilling is valid as a rule of thumb. ·The environmental impacts of the recycling processes should be minimized. ·Secondary products, material and energy carriers produced from waste should replace environmentally polluting products, materials and energy carriers. ·Incineration of fossil fuels (including plastics) should be avoided. ·Collection and transportation systems should be efficient ·Recycling of materials containing hazardous substances should be carefully considered. ·Efficient recycling may require advanced preprocessing (disassembly) before shredding.
