MAGNOLIA: An industrial tool for recycling and manufacturing high-performance permanent magnets to foster French sovereignty and the energy transition in France
Since they are used in electric vehicles and wind turbines, two markets undergoing strong growth, high-performance permanent magnets are strategic for the decarbonization of the economy. These permanent magnets systematically comprise rare earths, 80% of which are currently produced in China.
The MAGNOLIA project, launched in April 2022, brings together industrial and institutional partners in the high-performance permanent magnet sector: Orano, Valéo, Paprec, Daimantel France, and CEA. It aims to structure in France a sovereign, competitive, and cutting-edge sector for producing sintered permanent magnets.
Why focus on neodymium-iron-boron (NdFeB) sintered* magnets?
Among the various types of permanent magnets, NdFeB sintered magnets have the best magnetic energy density, making it possible to design electric motors that are more compact, lightweight, and efficient. In terms of their value, they represent 60% of the permanent magnet market, in which the volume of permanent magnets is expected to double over the course of this decade, generating high price tension.
*Sintering is a manufacturing process for parts that consists of heating a powder without causing fusion.
Objectives of MAGNOLIA by 2025:
- Develop innovative technologies for manufacturing sintered magnets in France and for deploying them on pilot and preindustrial manufacturing lines.
- Ensure security of permanent magnet supply and production outside of Asia.
- Lay the groundwork for a competitive sector in France for collecting, dismantling, and re-using electric motors.
- Reduce environmental impact through recycling magnets, reducing manufacturing waste, recovering rare earths, and ecodesigning electrical machinery to favor the dismantling of motors and the recovery of magnets.
MAGNOLIA is a project supported by France Relance as part of the drive to ensure the security of the energy transition and industrial relocalization in critical sectors.
