Institute for Global Environmental Strategies Institute for Global Environmental Strategies (IGES) Photo: Yasuhiko HOTTA � Founded in 1998 supported by the Government of Japan, � Policy research institute working to promote SD in the Asia-Pacific region, � 7 research areas: Climate Policy, Biofuels, Forest Conservation, Fresh Water, Waste and Resources, Capacity Development and Education, Business and Environment � Headquarters in Hayama (south of Tokyo), 3 other domestic offices (Tokyo, Kobe, and Kitakyusyu), and 2 international offices (Bangkok and Beijing) � Visit our website for details (www.iges.or.jp) IGES | http://www.iges.or.jp 3 Institute for Global Environmental Strategies Research objective and components Objective of the study • To propose an information exchange system for hazardous chemicals contained in electronic products, aimed at reducing environmental risks in end-of-life treatment. • Focused on Japan in the first stage, will expand to East Asia later Research components � Identify environmental risks (incl. environmental pollutions and occupational health issues) at the recycling and waste treatment stages � Analyze information needs and potential benefits of different kinds of information � Investigate what information can be generated at what stages � Analyze what kind of information system would be feasible and how it can be established IGES | http://www.iges.or.jp 4

Institute for Global Environmental Strategies Hypothesis - Potential Benefits � Information disclosure: from Producers to Recyclers � Safer recycling process Regulatory framework also needed � Higher recycling rate Economic benefits for recyclers � Less contaminated materials � Feedback: from Recyclers to Producers � Improve Design for Environment (DfE) Info. Disclosure Rationale: With improved knowledge on how Producers Recyclers Producers Recyclers products are recycled and how waste is treated, and on hazards related with those operations, Feedback producers can improve their product design .
