At　present,　the　research　on　the　recycling　of　bonded　Nd-Fe-B　magnet　wastes　is　primarily　conducted　at　the　laboratory　level.　This　study　presents　the　kilogram-scale　recycling　of　waste　bonded　Nd-Fe-B　magnets　using　a　NaOH-ethylene　glycol　solution.　The　impact　of　reaction　temperature　and　catalyst　concentration　on　the　recycling　process　at　this　scale　was　investigated,　and　regenerated　bonded　Nd-Fe-B　magnets　were　prepared　from　recycled　magnetic　powders.　The　magnetic　properties　of　the　recycled　powders　and　regenerated　magnets　closely　resembled　those　of　the　original　products.　Additionally,　a　life　cycle　assessment　was　conducted　to　analyze　the　production　and　recycling　process　of　bonded　Nd-Fe-B　magnetic　powders,　revealing　lower　environmental　impacts　for　the　recycling　process　compared　to　production.　Therefore,　successful　scale-up　recycling　through　a　NaOH-ethylene　glycol　solution　demonstrates　potential　commercial　and　environmental　opportunities　for　bonded　Nd-Fe-B　magnet　waste.
