Optimizing a Closed-Loop Supply Chain for Electronic Waste Management

This study explores the integration of reverse and forward supply chains into a Closed-Loop Supply Chain (CLSC) in the context of electronic waste network design and optimization in business and governance. It emphasizes the economic advantages and efficient management of Electronic Waste (E-waste), particularly in the context of End-Of-Life (EOL) products, as a response to the global E-waste crisis. This research introduces a novel mixed-integer linear programming model for an E-waste CLSC network, featuring hybrid manufacturing facilities and an objective function that maximizes the total profit to reduce disposal in landfills. The application of this model to a computer manufacturing network in Ontario, Canada is discussed. To this aim, the distances are calculated using Google Maps. The proposed model provides insights into the design and optimization implications of an electronic CLSC network. The proposed approach seeks to decrease E-waste by incorporating new and recycled components, with some recycled items sold in a secondary market. The findings offer a comprehensive understanding of product and part flows. The open facilities and the number of parts and products dispatched within each segment of the network are determined. This study concludes with a summary and recommendations.
