Heraeus Remloy

Neodymium-iron-boron materials from sustainable sources

Purchasing rare earth magnets from sustainably produced sources in Europe has been impossible up to now. As a full service provider along the supply chain, Heraeus Remloy closes this gap. Heraeus Remloy purchases end-of-life magnets, recycles these rare-earth magnets and produces neodymium-iron-boron materials, which are essential for future technologies. So we offer our customers a reliable long-term source of rare-earth magnets in Europe. Until now, neodymium-iron-boron materials have either been extracted from mines in Asia, which is associated with high environmental impact, or from energy-intensive wet-chemical reprocessing processes.

New process for the recycling of neodymium-iron-boron magnets

Neodym-Eisen-Bor Recycling Process

Rare earth-based permanent magnets such as neodymium-iron-boron (Nd2Fe14B1) have become an indispensible material in many everyday products and technologies. They are used for loud speakers, are essential for energy conversion in wind turbines, and are needed for electric motors. Up to now, only a small percentage of used magnets have been reprocessed. However, these reprocessing methods are energy-intensive with intensive use of chemicals and are mainly used in Asia.

Heraeus Remloy, in cooperation with the Fraunhofer Institute IWKS, developed a new method to recycle neodymium-iron-boron materials. This technical innovation not only makes reuse easier, but also enables companies to purchase permanent magnet material from controlled, environmentally friendly production.

Neodymium-iron-boron magnets: key technology with a problematic origin

Neodymium-iron-boron magnets: key technology with a problematic origin

There are severe ecological burdens in the mining of rare earths, which includes neodymium. Environmentally harmful chemicals have to be used and the process releases radioactive substances such as thorium. In addition, the reduction of rare earth oxides is very energy-intensive. The reprocessing of permanent magnets therefore offers high potential savings in terms of materials, energy and CO2 compared with conventional extraction from mines. Especially with regard to climate change, the savings in CO2 are significant.
