WEEE closed-loop supply chain network management considering the damage levels of returned products

Abstract

Due to economic, social, and environmental concerns, managing waste electrical and electronic equipment (WEEE) has become an important research area. The WEEE directive gives responsibility to producers for developing a system for recycling and disposal activities and handle all associated costs. This study proposes a mixed integer programming model for decision-makers to manage their activities on the WEEE closed-loop supply chain network. A decision-maker may be a single producer of any size or a managing body formed by a group of producers and/or third-party companies in the network. The model contributes to the research field by integrating product returns with different quality and damage levels. A set of scenarios was designed to evaluate the effects of the directive and the network design related issues (e.g., the minimum collection rates, the number of producers and stores in the network) on the objective function. The results indicate that the capacity balance among stores, producers, and recovery centers is vital to make the network profitable and sustainable. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.
