MagREEsource : the green Rare Earth Magnet company — •Sophie Rivoirard1,2 and Erick Petit2 — 1CNRS-UGA/Institut Neel, Grenoble, France — 2MagREEsource SAS, Grenoble, France
Nd-Fe-B is the most widely used hard magnetic material in applications including the electronic and automotive sectors, electromobility and wind powder (e.g. motors, turbines, magnetic valves, sensors). Current standard Nd-Fe-B magnets contain up to 30% of rare earth elements, such as Neodymium or Dysprosium, which are on the EU list of critical elements and which are, for more than 95%, mined in the People*s Republic of China. This sourcing raises both environmental and geopolitical issues while the present demand for rare earth magnets is increasing by a rate of nearly 9%/year due to an increasing production of green technologies items (electric vehicles, wind turbines*). Therefore, one incentive in the European Union is to develop recycling processes for Nd-Fe-B magnets. MagREEsource is a spin off company from CNRS founded in 2020, which benefits from more than 25 years of expertise within CNRS laboratories in Grenoble. MagREEsource has licensed the know-how and Intellectual Property developped in Neel Institute at CNRS Grenoble on the recycling of Rare Earth based magnets. MagREEsource is currently working on an industrial plant in the Rhone-Alpes region to start high scale production. As a player in the Circular Economy, MagREEsource's objective is therefore to promote magnets at the end of their life, by producing new magnets for European manufacturers of motors promoting a loop as short as possible between supply and customer.
