This final article in the series outlines potential pathways and strategies for overcoming industrial, economic, technological, and environmental barriers to NdFeB magnet recycling.
Having reviewed the industrial, economic, technological, and environmental challenges, it is crucial to identify viable pathways for advancing NdFeB magnet recycling. The goal is to secure resource efficiency while maintaining high coercivity and strong stability in recycled products.
One key strategy involves improving processes to ensure high-temperature resistance. Innovations in alloy design and controlled cooling techniques can help preserve thermal durability, making recycled magnets more competitive with new materials.
Developing advanced coatings is equally important to enhance corrosion resistance. Eco-friendly surface treatments can extend the lifespan of recycled magnets while minimizing environmental impact.
Another priority is boosting adsorption force. Precision material refinement and optimized sintering methods can restore the strong magnetic pull necessary for high-demand applications.
Moreover, recycling initiatives must align with modern industry demands for products that support customized magnet solutions. By tailoring recycled magnets to specific applications—such as automotive motors, wind turbines, and medical devices—the industry can strengthen adoption and market confidence.
Finally, collaboration between governments, research institutions, and private companies will be essential. Policy incentives, investment in R&D, and circular economy models are all necessary to transform NdFeB magnet recycling from a challenge into a sustainable opportunity.
