The purpose of this project was promoting the recycling efficiency of waste treatment organizations for waste electrical and electronic appliances in Taiwan. In order to effectively achieve the objective of this project and assist policy-making for government, this study mainly contains the following aspects: (1) investigation on the quantity and information of derived waste and regenerated materials for the waste electrical and electronic appliances that circulate in Taiwan; (2) searching for new foreign recycling technology and establishing a management system of hazardous substances including recycling rate; (3) establishing refinery technology system for the derived waste and the regenerated materials and establishing two integraed improving schemes, through the integration of current recycling and reuse agents; (4) establishing a materials supply system “Cradle to Cradle,” and providing guidance and assistance for waste treatment agents to promote their recycling performance. According to the survey results, that reuse ratio of the waste electrical and electronic appliances is 80% at the present situation. The market prices of reused appliances are not clear as a result of information enclosure by private agents. Waste plastics, wires, compressors, motors and printed circuit boards have large generation with high values therefore they can be integrated into the two improving schemes for further recycling promotion. China is the major receiving countries for waste electrical and electronic appliances, mostly metallic printed circuit board scraps and fenxie. Manual dismantling is the major processing method in China. The United States and Belgium have more advanced mechanical processing equipment for the complex waste composition. Currently the second-hand goods by law have no prduct standards therefore they still circulate outside of the EPA’s recycling system. Considering increasing resource recycling rate by the registered waste treatment agents, this project has two integration schemes: (1) addition of processing equipment and (2) establishment of new refineary agent based on mutual cooperation and alliances among currently registered recycling agents. The waste treatment agents should adopt a strategy of engaging in research and development towards an integrated resource recycling system development, and agressively develop for a breakthourgh in order to obtain higher profits and stability of growth. The short-term goal is to upgrade resource recycling of waste treatment agents; the medium-term goal is to improve resource recycling technology aggressively. In the long run, it is expected to expand the market of resource recovery as the ultimate goal.
