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.

稀土磁铁基于新近硼铁（NDFEB）是电动汽车中的关键材料，它们用于驱动机，发电机，动力转向和扬声器中。近年来，稀土的供应受到了主要生产国中国的巨大限制。稀土磁铁的回收带来了一个巨大的机会，并旨在为扬声器市场开发回收供应链。收获（从音频产品中提取稀土）将研究从汽车和消费者音频模块中解放稀土磁铁的新型方式。 EMR将预先处理汽车和平板电视扬声器废料，以提供含有NDFEB磁铁的废料组件的供稿。Harpromag将评估伯明翰大学将磁铁作为emagagneting Alloy Powder提取的磁铁，该过程与伯明翰大学一起评估专利的过程，该过程可用于磁铁再制造。将对来自各种来源的扬声器确定废料的质量，数量，可用性和价值，并将计算添加到废料中的值。与磁铁的一级生产相比，Hypromag Ltd开发的短循环回收过程将具有显着的环境益处。
