The environmental protection concept of"no waste city"is gradually accepted by people,and people are increasingly pursuing green and environmental protection.However,in this process,urban waste disposal and resource recycling are often neglected,so it is necessary to study the resource recycling path based on the construction of"waste free city".The results show that promoting the construction of"waste free city"can reduce the source pollution of waste and improve the reuse rate of resources.Among them,waste classification and recycling,the extension and expansion of industrial chain and government supervision are the three main paths for the construction of"waste free city".In addition,community participation and technological innovation are equally important for the construction of"waste-free cities".This study not only provides a concrete implementation path for the construction of"waste free city",but also provides guidance for the formulation and implementation of environmental protection policies.
