Discussion on the Impact Assessment of Hazardous Waste Municipal Environmental Risks under the Concept of “Waste-Free City”

Urban environmental management of hazardous waste is an important aspect of ecological civilization construction and ecological environmental protection, and an important part of winning the battle against pollution. The policy-driven characteristics of hazardous waste environmental management and utilization and disposal determine that institutional innovation should be emphasized in the construction of a “waste-free city.” This paper focuses on the environmental risk evaluation of hazardous waste cities, and uses the hierarchical analysis method to carry out empirical analysis using City A as an example. The results show that City A has a “high risk” due to the concentration of chemical and electronic industries, and high hazardous waste disposal volume and release rate. The study proposes to strengthen informationization supervision, implement regional joint prevention and control, improve disposal capacity, and other differentiated control countermeasures, in order to provide scientific support for the fine management of municipal hazardous waste and the construction of “waste-free city,” and help to improve the efficiency of hazardous waste treatment and reduce environmental hazards.
