Nehoire

Neohire: the main objective is to reduce the use of rare earth elements (REE), as well as Co and Ga (CRM), in the permanent magnets used in wind turbine generators (WTG). This objective is mainly achieved through the development of: 

a) a new concept of bonded NdFeB magnet able to substitute the present state-of-the-art sintered magnets for WT, and

b) new techniques for recycling the CRM from future and current permanent magnets (PM) wastes.
