摘 要：Availability of magnetic materials is most crucial for modern Europe,as they are integral to energy conversion across the renewable energy and electric mobility ***,there is still no circular economy to reuse and capture value for these types of *** the prediction that the need for NdFeB Rare Earth(RE)magnets will double in the next 10 years,this problem becomes even more *** the quality of the recollected materials varies significantly,the development of a classification system for recyclate grades of EOL NdFeB magnets in combination with an eco-labelling system for newly produced RE permanent magnets is proposed to clearly identify different magnet types and *** categorises the NdFeB magnets by technical pre-processing requirements,facilitating use of the highly effective HPMS process(Hydrogen Processing of Magnetic Scrap)for re-processing extracted materials directly from NdFeB *** proposed measures will have a great impact to overcome existing low recycling rates due to poor collection,high leakages of collected materials into non-suitable channels,and inappropriate interface management between logistics,mechanical pre-processing and metallurgical metals recovery.
