Накратко на български

Постоянните магнити от неодим, желязо и бор се изследват за нов начин на рециклиране чрез разделяне на частиците им. Това помага за намаляване на зависимостта от добива на редки земни елементи и понижава разходите за производство на електромотори и вятърни турбини.

Novel recycling and reprocessing of permanent magnets

The rare-earth (RE) based Nd-Fe-B magnets make up the key components of electric motors and generators which operate at high energy efficiency standards. The RE elements like Neodymium (Nd), Praseodymium (Pr), Dysprosium (Dy), and Terbium (Tb) which are necessary constituents of these magnets are listed as critical raw materials. Since the End Of Life (EOL) Nd-Fe-B magnets consist of 31-32 wt.% of REs so their recycling becomes necessary to reduce the supply-chain risks of these critical elements. It can also lead to the reduction of environmental hazards from mining of REs. The current magnet recycling is energy-intensive and economically not viable. The low-cost and eco-friendly magnet recycling technique developed in this MSCA project will enable the self-sufficiency of the RE magnet manufacturing industries in terms of supply-chain. It will boost the efficient use of resources and will reduce the cost of magnet manufacturing and the overall cost of electric motors and wind turbine generators. by moving to a clean, circular economy. This will encourage the society for widespread use of e-mobility powered by clean electric and wind power and will to the transition to a clean and circular economy. The overall objective is to introduce a new recycling route for EOL magnets by producing individual grains of Nd2Fe14B phase from scrap magnets and re-engineering them from the inside out. This will also advance the theory of coercivity in Nd-Fe-B magnets and produce highly demagnetization-resistant grain boundaries with ideal interfaces between the Nd2Fe14B phase and the grain boundary.

Цел на проекта

The transition to a low carbon society and energy efficiency by 2050 (“The EUs Green Deal”) will require radical solutions, especially in order to reduce greenhouse gas emissions, which have to be reduced by 80%. The major contributing segments are the development of e-mobility and eco-power generation, which will need highly efficient electric motors to meet the target. This can only be achieved by using high-performance rare earths-transition metal permanent magnets (RE-TM PMs) like Nd-Fe-B in such motors and generators. From this perspective, RE-TM PMs are an important subject of further research with aiming at even improved properties and performances. However, REs are on the EU's list of most critical raw materials, which requires holistic measures encompassing their recycling that will in the future accompany their primal development. There is already a large pool of RE-TM PMs based applications that are already at their end of life (EOL) (hard disk drives for example), the new e-applications like electric vehicles and wind turbines that are about to come to their end of life in the near future. However, the current recycling is too expensive for the EUs to conduct so, that is why the proposed project “nOvel reCycling And ReprocessIng of permaNent mAgnets”- OCARINA proposes a new feasible recycling technology of EOL magnets that would reduce EU dependence of RE imports. With this we are killing two flies in one run, as the new recycling route offers to tailor and improve the magnetic properties inside out, that was up to now impossible. ER is to tackle the proposed thematic is hosted by the Jožef Stefan Institute (JSI), Department for Nanostructured (K7) materials, where the complementary and synergetic knowledge are used for the project success.
