Abstract: With the deepening global development of a circular economy, the use of recycled materials as an important component of the circular economy has been adopted and implemented by an increasing number of manufacturing industries both domestically and internationally. However, the cost increase and lack of consumer acceptance associated with the proper use of recycled materials have made Chinese home appliance manufacturers struggle. This paper uses the Analytic Hierarchy Process (AHP) to identify key stages in the home appliance product value chain where the standardized use of recycled plastics is crucial. Then, it employs Data Envelopment Analysis (DEA) to evaluate the economic performance of different practices of standardized use of recycled materials in typical home appliance manufacturing enterprises. Finally, it proposes suggestions for a value closed-loop mechanism in the home appliance industry.
