Rare earth magnets based upon neodymium iron boron (NdFeB) are a key material in electric vehicles where they are used in drive motors,generators, power steering and in loudspeakers. In recent years the supply of rare earths has come under considerable constraint from the main producer, China. Recycling of rare earth magnets presents a significant opportunity and REAP aims to develop a recycling supply chain for the loudspeaker market. REAP (Rare-Earth Extraction from Audio Products) will investigate novel ways of liberating rare earth magnets from automotive and consumer audio modules. EMR will pre-process automotive and flat screen TV loudspeaker scrap to provide a feed of scrap components containing NdFeB magnets to HyProMag Ltd. HyProMag will evaluate a patented process in conjunction with the University of Birmingham to extract the magnets as a demagnetised alloy powder, which can be used in the remanufacture of magnets. The quality, quantity, availability and value of the scrap will be determined for speakers from various sources and a calculation of value added to the scrap will be made. The short loop recycling processes which are being developed by Hypromag Ltd will have a significant environmental benefit compared to primary production of magnets.

基于钕铁硼 (NdFeB) 的稀土磁体是电动汽车的关键材料，用于驱动电机、发电机、动力转向系统和扬声器。近年来，稀土供应受到主要生产国中国的严重限制。稀土磁体的回收提供了重大机遇，REAP 旨在为扬声器市场开发回收供应链。 REAP（从音频产品中提取稀土）将研究从汽车和消费音频模块中释放稀土磁体的新方法。 EMR 将预处理汽车和平板电视扬声器废料，向 HyProMag Ltd 提供含有 NdFeB 磁体的废料组件。HyProMag 将与伯明翰大学联合评估一项专利工艺，将磁体提取为退磁合金粉末，可用于磁体的再制造。将确定来自不同来源的发言者的废料的质量、数量、可用性和价值，并计算废料的附加值。与磁体的初级生产相比，Hypromag Ltd 正在开发的短循环回收工艺将具有显着的环境效益。
