Rapidly sintered re-engineered Nd-Fe-B permanent magnets based on recycled content

Purpose and goal:

The objective of the SIREN project is to develop a resource-efficient, environmentally-friendly procedure to reprocess and redesign end-of-life (EOL) Nd-Fe-B magnets and production waste. IVL will lead WP7 for the sustainability assessment that includes life cycle assessment, costing and health and safety.

Consortium is headed by Josef Stefan Institute. Expected results and effects:

Through its novel, environmentally friendly recycling process, SIREN will offer 100% recycled, advanced, Nd-Fe-B magnets, for use in wind-turbine generators and traction motors. This will strengthen the circular economy for rare-earth magnets and lift the reservations regarding the still relatively new green technologies to

change the public perception towards green transition initiatives. Approach and implementation: WPs will be split between four partners and an associated partner (PM manufacturer Magneti Ljubljana). WP1: Project Management (JSI, all partners) WP2: Recovery of hard-magnetic phase from feedstock material (JSI, MLJ, KU)

WP3: Novel grain-boundary phases (KU, JSI, KUL) WP4: Rapidly-sintered magnets produced via RAS process (JSI, KUL) WP5: Thermal-electrical-mechanical sintering model (KUL, JSI, KU) WP6: Thermodynamic and kinetic database construction (KUL, JSI) WP7: Environmental and circular economy impacts (IVL, all partners)

WP8: Dissemination and Exploitation
