As part of the GENESIS joint project funded by the BMWK, the direct recycling of scrapped NdFeB permanent magnets was investigated. The study "Direct Recycling of Hot-Deformed Nd–Fe–B Magnet Scrap by Field-Assisted Sintering Technology" shows ways of reducing critical raw materials.

NdFeB magnets are extremely powerful and an indispensable component of efficient electric motors and generators. However, large quantities of neodymium are required for the conventional production of NdFeB magnets. This element, like some of the other components it contains, belongs to the group of rare earths, which are classified as critical raw materials in the EU. By applying a combination of innovative field and pressure assisted sintering and forming processes, it has again been possible to produce anisotropic NdFeB permanent magnets from up to 100% mechanically crushed NdFeB scrap. Thus, the now published study can contribute to a future reduction of the environmentally harmful extraction of rare earths.
