Abstract: The recycling problem for electronic products under a closed-loop supply chain environment is addressed in this paper. The cycling efficiency is analyzed by using material flow analysis (MFA). Then, a mathematical model is developed to optimize the recycling efficiency for such a supply chain. By this model, the circulation index and path length are measured by the amount of the substance at each node in the system, which reflects the material utilization and recycling efficiency of the whole system. Thus, it reveals how one can increase the resource recycling efficiency. It shows that the circulation index can be improved by green manufacturing and green design. This is a significant finding in this field. Finally, the model is tested and analyzed through an e-waste recycling numerical example.
