![]() ![]() Recent geopolitical REE supply risks have triggered an interest in their recycling, among other strategies followed to alleviate potential supply risks. ![]() Rare earth elements (REEs) play a key role for the advancement of green technologies, with permanent NdFeB magnets for efficient motors accounting for one of the most important applications in terms of REE market value. ![]() The study also highlights that perfluorocarbon emissions, which occur during primary rare earth production, warrant further investigation. The comparison of this recycling route with primary production shows that the recycling process has the potential for much lower process-specific impacts when compared against the current rare earth primary production route. We conducted a life cycle assessment study to provide a quantitative estimate of the impacts associated with the process being developed and to compare the prospective impacts against those of the current state-of-the-art technology. Conducting life cycle assessment at R&D stage can provide valuable information to help steer process development into an environmentally favorable direction. It is expected to be environmentally beneficial when compared to longer processing routes. The process is being developed on a laboratory scale and has been proven to work in principle. Rare earths are required in their metallic form for the production of new NdFeB magnets, and the suggested process achieves this through a single step. A new recycling process for the extraction of rare earths from neodymium–iron–boron (NdFeB) magnet scrap is being developed, based on the direct extraction of rare earths from end-of-life magnet material in a molten fluoride electrolysis bath. ![]()
