Sustainable Recovery, Reprocessing and Reuse of Rare-Earth Magnets in a Circular Economy (SUSMAGPRO)

Descrizione del progetto

Nuove tecnologie per il riciclaggio dei magneti al neodimio

I magneti di terre rare (magneti al neodimio-ferro-boro), il tipo più forte di magneti permanenti disponibili, sono ampiamente utilizzati nella produzione dei moderni prodotti tecnologici. Sono applicati in elettronica, nelle turbine eoliche, nei motori per auto elettriche e in altri campi. Purtroppo, la maggior parte dei magneti al neodimio disponibili sul mercato dell’UE provengono da paesi terzi. Il progetto SUSMAGPRO, finanziato dall’UE, mira a sviluppare una catena di approvvigionamento pilota di magneti al neodimio riciclato in Europa. Il prodotto sarà testato con il supporto di un team multinazionale e delle nuove tecnologie sviluppate nell’ambito del progetto Remanence del 7° PQ. Queste nuove tecnologie dell’idrogeno saranno utilizzate nel processo di separazione e purificazione. Si procederà quindi alla rifabbricazione per ottenere diverse forme di magneti e si valuterà il potenziale del nuovo metodo.

Obiettivo

The aim of this project is to develop a recycling supply chain for rare earth magnets in the EU and to demonstrate these new materials on a pilot scale within a range of application sectors.

Rare earth magnets based upon neodymium-iron-boron (NdFeB, also containing dysprosium) are used in a wide range of products, including for example clean energy technologies (wind turbines and electric vehicles) and high tech sectors such as electronics. However in recent years the supply of these materials has come under considerable pressure and neodymium and dysprosium are now deemed to be of greatest supply risk for all elements.

The EU imports far more NdFeB magnets than it manufactures (>1,000 tonnes manufactured per annum). It has been estimated that ~ 2,000-3,000 tonnes/annum of NdFeB will be available by 2020 for recycling, which presents a significant opportunity. The aim of this project is to identify, separate, recycle and demonstrate recycled magnets at a pilot scale with a multidisciplinary team located across the EU. The project will target three of the main application sectors including automotive, electronics and wind turbines.

The project will develop new sensing and robotic sorting lines for the identified EoL products, building upon technologies developed in the FP7 project Remanence. New hydrogen based technologies will be demonstrated at scale for separating and purifying NdFeB powders from the robotically sorted parts and this technology will be duplicated at another partner in the project. The separated powders will be re-manufactured into sintered magnets, injection moulded magnets, metal injection moulded magnets and cast alloys, at 4 different companies across 3 countries, building upon work in the Repromag Horizon 2020 project. A techno economic assessment will be performed for each potential recycling route alongside a life cycle assessment to assess the environmental benefits over primary production.
