Project description
Novel magnetic material recycling process
The threat of climate change has prompted companies to introduce green products and technologies to reduce emissions and pollution. Most important of these technologies are the electric/hybrid electric vehicles, which use permanent magnet-driven electric motors. Unfortunately, the manufacturing lines of these magnets and the sheer demand for them being machined to a tailored geometry, have led to a waste of around 30 % of the magnetic material. Despite many options for recycling, magnetic material remains cost-inefficient and leads to the waste of other important resources such as Rare-Earth Elements. The EU-funded GYROMAGS project aims to change this by developing a novel magnetic material recycling process utilising electro-deoxidation to consume less energy. Moreover, it requires few other acids and chemicals, reducing water and energy consumption and keeping costs low.
Objective
Permanent magnets (PM) have a wide range of applications and play an important role in the realization of a sustainable future. With the increasing demand for green and renewable energy production and sustainability, comes a rise in popularity and demand for electric vehicles (EV) and hybrid electric vehicles (HEV) which use permanent magnet-driven electric motors. However; the development of technology and shrinking dimensions of parts used for such technologies has made post-processing and machining of the bulk PMs inevitable. This, in turn, leads to a 30% waste of the magnetic material as swarf/rejects. PMs are made of a combination of Rare Earth Elements (REE), transition metals (TM) and, some other elements. The scarcity of the REEs and volatile and unstable price of the TM market (especially Cobalt) has pushed the EU to encourage scientists to come up with feasible methods to revive the mentioned waste and thus achieve a circular economy and guarantee sustainable energy production and by doing that help the EU to achieve it's Green Deal Initiative goal set for 2050. The recycling of Samarium-Cobalt (Sm-Co) permanent magnets has been the target of a number of scientific studies, however; the proposed methods are all very energy-intensive and require a lot of mineral acids, and generate a huge amount of wastewater during the process. In this proposal, we suggest a green and facile method based on electro-deoxidation of the oxidized magnet swarf which will require much less energy consumption and will require a negligible amount of acids and chemicals compared to the conventional methods.
