Abstract

The advanced loop-closing challenges to promote industrial ecology especially emphasize the utilization of the recovered materials/parts/products in original and principal production system while keeping their original function at the highest level possible. In this study, first the advanced loop-closing systems in recycling end-of-life vehicles and electric household appliances are designed in “Hyogo Eco-town”. Second the methodology to evaluate the eco-efficiency for advanced loop-closing systems is developed. Finally the eco-efficiency based on results of Material Flow Analysis and Life Cycle Assessment is evaluated for the advanced loop-closing strategies in the recycling of two end-of-life products.
