Abstract
Recoverable amounts of rare earth magnets (neodymium magnets) were estimated based on data collected from models of appliances using compressors and motors similar to those found in air conditioners and washing machines collected through current home appliance recycling systems, specifications, and contents. The composition and characteristics were analyzed, and the deposits and environmental load reduction effects were estimated based on the grade of rare earth contained. Additionally, the efficiency of the rare earth magnet recovery process, which has been added to the current compressor disassembly process, was examined technically. Results show that not only is the recycling of rare earth magnets from used home appliances feasible, but also necessary from a resource security point of view.
