使用済自動車の静脈系LCAを通じた環境影響低減プロセスの抽出

Abstract

End-of-Life Vehicle (ELV) Recycling Law has been ensured since January 2005 and Automobile company and importer have been required to manage fluorocarbons, air-bags and Automobile Shredder Residue (ASR). These companies are changing an ASR treatment method from landfill to incineration with thermal recovery because the law also requires them to increase recycling rate more than 70% of ASR by 2015. This study is to assess these ELV treatment methods to find the effects of the law and important processes to reduce environmental impacts. The assessed ELV treatment methods of this study are a) a shredding and landfill type, b) a shredding and heat recovery type, c) a pressed ELV recycling on electric furnace type and d) pressed ELV recycling on converter type.As a result, fluorocarbons collecting rate and re-use rate of main parts are specified as more important processes for reducing environmental impacts than others. It is found that ELV and ASR transport process are less important. There is no clear difference of environmental impacts among lawful types, though, these types are about 3000 kg-CO2 equiv. less than the traditional type, a) a shredding and landfill type.
