Rare earth elementRare earth elements bearing permanent magnetsPermanent magnets are crucial components for several key industries contributing to the green transition such as wind turbines and electrical vehicles as well as consumer electronics such as computers, smartphones, and household appliances. The lifetime of these magnetsMagnets depends on the application, ranging from 2–3 years in consumer electronics to 20–30 years in wind turbines. These magnetsMagnets must be recycled for a sustainable and secure supply chain for the current and future applications due to raw material availability issues and the volatile market. Thus, the end-of-life (EoL) magnetsMagnets can be classified as a valuable secondary resource. Moreover, the recyclingRecycling of NdFeB magnetsNdFeB magnets includes not only from EoL products but also from the waste generated during their production, providing a comprehensive approach to the circular economy. Various techniques have been investigated for the recyclingRecycling of EoL permanent magnetsPermanent magnets. These methods include not only direct reuse of the magnetMagnets, or reprocessing after hydrogen decrepitation, but also pyrometallurgical and hydrometallurgical processes to recover the raw materials. This multifaceted approach to recyclingRecycling operations reflects the complex nature of NdFeB magnetsNdFeB magnets and points out that the processing challengesChallenges have not yet been overcome, since there is still no industrial level recyclingRecycling of these valuable secondary sources. Each of the techniques described has distinct advantages and disadvantages that require a thorough evaluation of the potential challengesChallenges of their industrial application.
