The guidance of circular economy principles also promotes the technological innovation and industrial upgrading of the magnetic component industry. In order to meet the requirements of circular economy, the industry has increased R&D investment in green magnetic materials, efficient recycling technology and remanufacturing technology, and a number of low-carbon, high-efficiency and recyclable new technologies and new processes have emerged, driving the industry to move towards high-end and green. On the other hand, circular economy promotes the optimization and reconstruction of the industrial chain, forming a collaborative model of "production enterprises - recycling enterprises - remanufacturing enterprises", realizing the full-cycle management of resources from production to recycling, and improving the overall competitiveness of the industry. With the global emphasis on circular economy and sustainable development, the magnetic component industry will further deepen the practice of circular economy principles, strengthen the research and development of key recycling technologies, improve the recycling system, and realize the transformation from resource-dependent to resource-recycling. Guided by circular economy, the magnetic component industry will not only solve the problems of resource shortage and environmental pressure, but also open up a new path of sustainable development, and provide a solid support for the green transformation of downstream manufacturing industries.
Resource utilization is the core support for realizing closed-loop recycling of magnetic component industry, focusing on efficient recycling and regeneration of waste magnetic materials and waste components. Waste magnetic components contain a large amount of recyclable rare earth metals, iron and other resources, and efficient recycling technology is the key to resource utilization. A new generation of green recycling technology breaks through the limitations of traditional acid leaching and pyrolysis processes, with low pollution and high recovery rate, and can efficiently separate and extract rare earth elements and metal resources from waste magnetic materials, with a resource recovery rate of more than 95%. The recycled magnetic materials can be reprocessed into high-performance magnetic materials through smelting, forming and performance optimization, and put into the production of new magnetic components again, realizing the closed-loop recycling of resources. At the same time, the industrial chain collaboration of resource recycling is strengthened, and a professional recycling and processing system is established to realize the standardized collection, classified processing and centralized regeneration of waste magnetic components, solving the problems of scattered waste sources and difficult recycling.
Reduction is the primary link of circular economy practice in the magnetic component industry, focusing on reducing resource consumption and carbon emissions from the production source. In terms of raw material optimization, the industry is accelerating the research and development and application of high-performance, low-resource magnetic materials, replacing high-resource-consuming rare earth magnetic materials with low-rare-earth or non-rare-earth magnetic materials, and reducing the dependence on scarce rare earth resources through grain boundary engineering, material doping optimization and other technologies. At the same time, through magnetic circuit simulation and structural optimization design, the magnetic performance of single component is improved, the amount of magnetic materials used is reduced under the premise of ensuring product performance, and the resource consumption per unit product is reduced. In the production process, the industry promotes green and low-carbon production processes, replaces high-energy-consuming smelting and forming processes with energy-saving and efficient preparation technologies, recycles production waste heat and waste water, reduces carbon emissions and pollutant emissions in the production process, and realizes clean production at the source.
Reuse is a key link to extend the service life of magnetic components and improve resource utilization efficiency. For magnetic components with normal magnetic performance and no structural damage in the process of use, through standardized testing, cleaning and performance calibration, they are reused in industrial scenarios with lower performance requirements, avoiding direct scrapping and shortening the service cycle. For magnetic components with partial performance attenuation, the magnetic performance is repaired and upgraded through magnetic field remagnetization technology and local structural modification, so that they can meet the use standards again and extend the service life of products. In addition, the modular design of magnetic components is promoted, so that damaged parts can be disassembled and replaced separately, instead of overall scrapping, reducing the generation of waste and improving the reuse rate of components. The reuse link not only reduces the demand for new raw materials, but also reduces the production cost of enterprises and improves the economic benefits of the industrial chain.
