Modelling the Metal Recycling Efficiency for Waste PCBs : A new approach with MEMRECS concept

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 PCBs. MEMRECS can provide the result that enhances the role of metal recycling as raising the sustainability of production by reducing the need for primary production, thus saving energy and extending the longevity of natural resources.
