Collaborative reverse logistics network for electric vehicle batteries management from sustainable perspective

With the proposal of carbon neutralization, countries pay much more attention to environmental protection. As waste electric vehicle battery (WEVB) has an important impact on the environment, its reverse logistics process has been a vital issue, in which an excellent reverse logistics network (RLN) becomes a prerequisite for waste recycling, cost reduction, profit increasement and efficiency improvement. However, reverse logistics network design (RLND) for WEVBs is still a significant challenge. In general, the amount and quality of the returned product in a RLN are highly uncertain, and the WEVB market in China is no exception to this. From a circular economic and environmental perspective, this paper is devoted to designing a multi-participants-based RLN for WEVBs, considering recycling and remanufacturing processes. Then, a fuzzy optimization model is proposed to determine the number and location of facilities in this RLN, promote sustainable development, reduce envi-ronmental pollution, and consider carbon emissions and two types of WEVBs. Finally, the results from a case study in Chongqing show good performance in cost reduction, profit increasement and efficiency improvement, which could significantly support the decision-making of WEVBs recycling.

Automated summary

This paper focuses on the reverse logistics issue of waste electric vehicle batteries (WEVBs). From the perspective of circular economy and environmental protection, a multi-participants-based reverse logistics network is designed, and a fuzzy optimization model is proposed to determine the number and location of facilities in the network, aiming to achieve cost reduction, profit increasement and efficiency improvement.
