EU Targets NdFeB Magnet Data for Circular Economy

Why this is here: The NEO-CYCLE project exemplifies the importance of NdFeB magnets as a secondary source of elements for applications in the pharmaceutical, chemical, and ammonia industries.

Researchers defined data requirements for digital product passports (DPPs) of neodymium-iron-boron (NdFeB) magnets in the European Union. The study integrates literature, legal frameworks, and input from the NEO-CYCLE project. It focuses on improving recovery and recycling of these magnets, which are key to sourcing elements for industries like pharmaceuticals.

The research revealed limited prior work on data needs for sustainable end-of-life (EoL) processing of NdFeB magnets. Existing EU legal approaches cover most product data, but transferring data throughout the supply chain presents a challenge. Researchers propose batch-based digital material passports (DMPs) using automated scanning to track mixed magnet batches.

Establishing standardized data definitions and addressing uncertainty from mixing DPP-equipped and non-equipped products remain unsolved problems. Further research will focus on these issues to support scalable EoL processing of NdFeB magnets and meet EU circular economy objectives.
