Evaluation Method Of Automobile Recycling Systems For Asia Considering International Material Cycles: Application To Japan And Thailand

摘要

To examine an appropriate recycling system for end-of-life vehicles (ELVs) from Japan in the context of Asia, an Asian international automobile recycling input-output (AI-ARIO) analysis is presented. The AI-ARIO analysis spatially expands the existing ARIO analysis within the framework of the waste input-output (WIO) analysis developed by Nakamura et al., which considers the interdependence between the flow of goods and wastes in a country. This analysis focuses on the local and global cycles for ELVs in Asia and can evaluate the environmental and economic effects of alternative recycling systems. We estimated the AI-ARIO table for Japan and Thailand and applied it to scenario analyses covering the restriction of ELV trade between the two countries, the introduction of new recycling techniques in Thailand, and centralized treatment in Japan. We verified the applicability and effectiveness of the AI-ARIO analysis through the scenario analyses.
