Pricing and coordination of waste electrical and electronic equipment under third-party recycling in a closed-loop supply chain

Waste electrical and electronic equipment have the potential environmental risks and resource value simultaneously. So the product recycling is very important. This paper studies on recycling problems of WEEE under the third-party recycling in a closed-loop supply chain. We take the following measures. Firstly, based on classifying the WEEE, we consider a revenue sharing and cost sharing contract as the coordination mechanism. Secondly, under centralized and decentralized decisions, we use the game analysis technology to determine the optimal pricing and profits, respectively. Finally, we conduct the number simulation to illustrate and validate the proposed models and provide managerial insights. The results show that when retailers sell new and second-hand products simultaneously, consumers become more sensitive to recycling prices, the profits of manufacturers, recyclers and CLSC increase. However, the retailers' profits decline.
