Sustainable Mining and Metallurgy

At present, with the public's attention to environmental protection and resource sustainability, the effective treatment of hazardous waste has become a global problem. This paper reviewed the current situation of China's hazardous waste treatment industry and the evolution of hazardous waste related policies, and proposed a circular economy model of ‘source reduction + process reuse + end treatment’ for hazardous waste treatment.Taking an industrial park in Quzhou as an example, the three major cycles of enterprise internal circulation, industrial internal circulation and park internal circulation formed by hazardous waste treatment were introduced, the process of material circulation flow of “resource product hazardous waste renewable resource” were analyzed, the feasibility of resource recycling was explored , and suggestions on hazardous waste treatment under circular economy mode from the perspectives of policy, technology, economic benefits and management supervision were put forward.
