Improving recycling markets Markets for many classes of potentially recyclable materials are growing. However market failures and barriers are constraining some markets. Factors such as information failures technological externalities and market power can affect the prices quantity and quality of materials traded. This report presents the case for the use of industrial policies which address such market failures and barriers and these policies are seen as complements to more traditional environmental policies. Indeed encouraging ever higher recycling rates in the absence of such complementary measures may impose very high social welfare costs. This publication covers in particular the markets for waste oils waste plastics and used rubber tyres.
