Method of the Waste Electrical Reverse Logistics Environmental Impact Assessment Based on Rough Set Theory

Abstract

Based on the principle of the ISO14042 standard on life cycle impact assessment, the paper uses the environmental eco-indicators to evaluate the environmental impact of waste electrical in reverse logistics. Firstly, build environmental impact indicator system based on the method of eco-indicator99, and use rough set theory to calculate the weight of all the indicators. Then combine the weight with eco-indicator99 database to calculate the environmental eco-indicators. Finally, take waste refrigerator for example to illustrate the process of environmental impact assessment of general waste electrical.
