The hard magnetic materials play an important role in modern technology, e.g. automotive, electronics and many daily use equipment. The overview of statistics indicates that over the next few years the continuous increase of their consumption will be observed. Currently, China is the largest importer of rare earth elements, from which RE-M (rare earth elements, transition metal) magnets are produced. This situation is inconvenient for European countries because of their dependence on the largest producer. That aspect combined with high material and production costs makes the investigation into possibilities of effective recycling methods of hard magnets a research area of significant importance.In the paper the characteristic of magnetic composite material based of RE-M-B (rare earth elements, transition metal, boron) powder has been presented. For the research, the new magnetic material had been prepared from recycled hard magnetic elements (from electric motors) and the plastic as a binding material. The magnetic material characteristic includes, a brief outline of the recovery technology (treatment and processing of recycled permanent magnets) as well as a package of materials research analysis. The paper brings the opportunities to introduce the hard magnets recycling technology on an industrial scale.Keywords: NdFeB magnets, recycling, rare earth elements
