The main frame of this study is the analysis of the metal recyclability from waste PCBs with three material recycling quoting approaches: Material Recycling Efficiency (MRE) which is based on solely weight basis, Resource Recovery Efficiency (RRE) which is based on natural resource conservation aspect, and Quotes for Environmentally Weighted Recyclability (QWERTY) which is based on environmental impact aspect. Furthermore, this study proposes the Model for Evaluating Metal Recycling Efficiency from Complex Scraps (MEMRECS) as a new approach to quotes the metal recycling performance for waste...
