Comparison of Waste Lithium-ion Batteries Recycling Methods by Different Decision Making Techniques

Today, in order to reduce fossil fuel consumption and to prevent gas emissions that are increasing day by day, vehicles working with electrical energy have started to be produced and developed. The environmental impact of the batteries of an increasing number of electric vehicles is an undeniable fact and is predicted to pose a huge problem. In this study, alternative recycling processes have been determined by examining the literature and the applications for waste lithium-ion batteries, and these processes have been compared with the different decision making techniques (Analytic Network Process (ANP) and TOPSIS) with technical, economic and environmental dimensions. In addition, sensitivity analysis has been applied for robustness of the results. For the wastes, the most appropriate recycling method in the context of circular economy has been determined as “Direct Recycling”in all of the studies.
