Evaluation of Recycling System for End-of-Life Vehicle based upon Environmental Accounting for Multiple Economic Sectors

Abstract

This study aims to evaluate ELV (: End-of-Life Vehicle) recycling system based upon environmental accounting for multiple economic sectors for a case study toward loop-closing society. These days ELV recycling system draws attention in two aspects; improving the rate of recycling of ASR (: Automobile Shredder Residue) and deterioration of Fe-scraps and Automobile-press. As the most important problem, Cu which is contained in electronic and electrical systems of vehicle, has had large influence on quality of Fe-scraps. For the method of cutting down ASR more efficiently and effectively without mixing Cu into Fe-scraps, 10 ELV recycling scenarios are developed by existing technology and weighed up. Consequently a new ELV recycling scenario, the exhaustive removal of Cu by the disassembly sector and the gasification of ASR by the shredder sector, is proposed as most effective alternative.
