Decarbonization of remanufacturing processes in circular supply chains: case study on rubber recycling industry

Purpose At present, relevant studies on circular supply chains are gradually increasing. However, the majority only focus on precautions or obstacles in the implementation of supply chains, rather than delving deeper into the decarbonization of processes within circular supply chains. Therefore, this study took the rubber recycling industry as an example, highlighting the decarbonization of the manufacturing process for remanufactured products in this industry. Subsequently, a feasible framework for future practice was established, serving as a valuable reference for companies in the industry. Design/methodology/approach This study first selected key factors from the initial aspects and criteria using the fuzzy Delphi method (FDM), followed by ranking the importance of the selected aspects and criteria using fuzzy decision-making trail and evaluating laboratory (FDEMATEL). Findings This study has confirmed which directions the manufacturing processes of remanufactured products need to move toward so as to achieve the goal of decarbonization when implementing circular supply chains. The main aspects include environmental, social and economic benefits as well as value recovery. In addition, the main directions for implementing circular supply chains in the industry are cooperating with different supply chain partners, having effective reverse logistics systems, collaborating with multiple companies, optimizing technology and developing the industrial symbiosis network. Research limitations/implications Research results vary due to industry differences. Although the results of this study can be used for reference in other high-pollution industries, they are unable to be perfectly in line with their current states. Therefore, more in-depth research is needed in the aspect of decarbonization for other industries. Originality/value The rubber recycling industry chosen by this study is different from general industries since its raw materials consist predominantly of waste. Therefore, it is an imperative trend to perform decarbonization in circular supply chains. This study establishes a novel framework to provide industry players and their stakeholders with clearer and more targeted implementation objectives for reference.
