To ensure the safety of national metal resources by recycling metal resources

Secondly, increase the development of metal cycle key technologies and environmental protection technologies to achieve product performance and environmental protection levels. First, break through the bottleneck of key core technologies in the industry. In view of the characteristics of secondary non-ferrous metal resources, such as high complexity of original components, high volatility of component content, high density and compound of materials, etc., which are different from mine resources, precise layout of key technical routes, especially increasing the comprehensive utilization of electronic products and the development of a full set of technologies. Breakthroughs have been made in the remanufacturing of high-end new energy materials, the preparation of high-purity metal and photoelectric materials, and the preparation of fine powder materials, improving product performance and added value. The second is to break through the bottleneck of environmental protection of secondary metallurgy, giving priority to the use of high recovery rate, low energy consumption, short process, and clean slag pollution-free technology. Promote the cascade utilization of solid waste, metal parts repair and recycling, additive manufacturing and other clean production processes, and increase the "three wastes" treatment, organic electrolyte harmless technology research and development and promotion. The third is to increase the development and use of automatic equipment. Breakthrough in intelligent label technology and equipment, portable automatic detection and sensor identification equipment, automatic sorting and recycling equipment for waste goods and other key technologies and equipment, greatly optimize the current sorting process. The fourth is to promote the digital transformation of the whole production line by upgrading technology and equipment. Using new technology to optimize the production line process and improve the quality of product control; The digital transformation of the whole production line is promoted by the digitization of process flow, unit equipment and control system.

Second, improve the overall plan and optimize the industrial layout. First, optimize the industrial spatial layout. Based on the analysis of national geography and big data of metal resources, with the market as the main body leading the allocation of resources, and comprehensive data of metal waste sources, industrial supporting, product markets, environmental bearing, transportation and other aspects, the spatial layout of national metal resource recycling industrial parks is planned. It is necessary to avoid duplicate investment and overcapacity caused by homogenization competition, improve the level of industrial intensification, and do a good job of circular industry macro planning for different metal product categories.

Secondly, optimize the industrial chain layout of the park. Centering on the core metal varieties of the park, the whole industry complete chain of "recycling - pre-treatment - primary processing - deep processing - sales" is formed inside the park, and a large-scale comprehensive circular economy park is built. Promote the construction of a third-party environmental management service system for the recycling of industrial solid waste, and encourage the development of a professional systematic solution model for the source management, recycling, comprehensive utilization and harmless disposal of industrial solid waste.

Finally, build the super-cycle industry network. Promote the symbiotic coupling among metal-related enterprises, industries and industries, form an industrial network of circular links, promote the sustainable development of the park and the cooperation of cross-provincial parks, and form a large-scale cross-regional cycle of multiple metals. Comprehensively analyze the big data of the geographical distribution of metal resources in China, the big data of regional resource supply and demand, and the big data of transportation, and simulate the recycling industry for different forms of metal distribution, form a multi-level circulation and supply model, and realize the multi-point circulation and regional supply of uniformly distributed minerals (copper, lead, zinc, iron, etc.) throughout the country. Distributed minerals (cobalt, magnesite, chromium, etc.) regional cooperation cycle, the whole region supply, concentrated distribution of minerals (aluminum, tungsten, tin, etc.) the whole region large-scale circulation, the whole country supply.

Third, strengthen policy support and expand the scale of industry. First, improve legal standards. It is suggested that legislation should be passed to promote the ecological transformation of the product end, and recycling should be regarded as the standard and requirement in the product development and production design stage, so as to improve the convenience of recycling, processing and dismantling. Establish a product labeling system to make it clear that manufacturers must label components using key strategic non-ferrous metals and products using harmful metal substances such as lead and mercury to improve the recycling rate of key minerals; Make it clear that manufacturers and sellers share the obligation of recycling waste products, and establish recycling channels for waste industrial products; It is clear that consumers sign an agreement when they buy products, and ensure that products are recycled through formal resource channels when they are discarded.
