MAGELLAN research was presented at JEMS 2025, the Joint European Magnetic Symposia, held in Frankfurt, Germany, from 24 to 29 August 2025. The event brought together the magnetism and magnetic materials research community, with a scientific programme including plenary lectures, contributed talks and poster sessions on cutting-edge developments in the field.
During Poster Session I, Aybike Paksoy from TU Darmstadt presented MAGELLAN’s research through a poster titled “Towards Sustainable Nd–Fe–B Magnets Using Advanced Recycling”. The poster focused on recycling strategies for end-of-life Nd-Fe-B permanent magnets.
The presented work addressed one of the key challenges tackled by MAGELLAN: reducing reliance on primary rare earth element supply by improving the recovery and reuse of permanent magnets. Nd-Fe-B magnets are essential for clean energy technologies, including permanent magnet motors and electric generators, but their dependence on rare earth elements creates environmental, economic and geopolitical concerns. In response, the poster highlighted advanced recycling approaches for scrap magnets recovered from electronic waste rotors, including hydrogen decrepitation, jet milling, sintering, hot pressing and spark plasma sintering.
The research showed that different recycling routes can be used to obtain competitive magnetic properties from recycled Nd-Fe-B feedstock. It also underlined that end-of-life magnets can vary significantly in composition, degradation level and magnetic performance, making it important to tailor the recycling route to the original magnet type and production route. This finding is directly relevant to MAGELLAN’s work on sustainable permanent magnet recycling, circular rare earth value chains and resilient supply chains for Europe.
Through this poster presentation, MAGELLAN contributed to scientific exchange on sustainable magnetic materials and demonstrated how advanced recycling can support the development of more circular and resource-efficient Nd-Fe-B magnets for clean energy and mobility applications.
