Urban mineral development and utilization: prospects, influencing factors and management policies

Urban mineral development and utilization is a management method based on the circular economy that converts waste into renewable resources, which helps to improve resource consumption and sustainability in the circular economy. Through comprehensive and in-depth combing of the relevant research, it is helpful to deepen the systematic understanding of urban mineral development and utilization. Firstly, analyzes the prospects of urban mineral development and utilization from the social stock, development value and development and utilization mode of urban minerals. Secondly, the influencing factors of urban mineral development and utilization are discussed around technical conditions, cost-effectiveness and policy environment. Finally, the management policies of urban mineral development and utilization are analyzed from three aspects: the status quo of the policy system, the effect of policy tools and the top-level design of policies. The results show that typical urban minerals are not only rich in reserves, but also have great development value, but there are still many problems and challenges, such as the actual recovery rate is not high at this stage. Therefore, it is necessary to vigorously develop new technologies and increase the proportion of formal recycling channels to improve the efficiency of urban mineral development and utilization. In addition, the national level should organically integrate the circular business model and extended producer responsibility (EPR) model into the management policy system of urban mineral development and utilization, and build an industrial ecological chain for the development and utilization of renewable resources. Finally, the future research direction of urban mineral development and utilization is envisioned.
