Abstract

Abstract

The proposal of “zero-waste city” construction pilot symbolizes the implementation of the “zero-waste society” strategy in China. In this study, material flow analysis was used to quantify urban material metabolism in Panjin from 2005 to 2018. The comprehensive evaluation of the analytic hierarchy process and entropy weight method was adopted to evaluate the development level of the urban economy, resources, and environmental subsystems. Using system dynamics, this paper explored the potential of “zero-waste city” comprehensive management to optimize urban metabolic systems compared with other development modes. The results showed that the material input-output of Panjin had the characteristics of high input, high emission, and high hidden flow. The limited development of resource efficiency affected the overall level of urban metabolism. Under the comprehensive management mode of “zero-waste city”, it was expected to increase resource productivity by 20.29% and environmental efficiency by four times by 2025, based on 2018, greatly promoting the optimization of resources, environment, and economy of the urban metabolic system.
