GREENE, short for SINGLE-GRAIN RE-ENGINEERED ND-FE-B PERMANENT MAGNETS, is an EU-funded project focused on pioneering advancements in high-performance permanent magnets, re-engineering their microstructure to make them more powerful while at the same time reducing Rare Earth (RE) content. Led by the Slovenian Jožef Stefan Institute, our consortium of 15 European partners is tackling the environmental and supply challenges associated with these crucial components of high-tech products that power a green energy future, such as e-vehicles and wind turbines.
Resource-efficient, high-performance Nd-Fe-B magnets with -20% RE content, +20% coercivity, and maximum energy product by 20%.
Independent, resilient and scalable supply of key materials, magnets and components within Europe.
Increased sustainability of magnet production with -5% scrap rates, -15% energy consumed and -30% toxicity.
Society and stakeholders better equipped for a sustainable green transition in Europe.
GREENE brings together 15 leading organisations from across Europe, each contributing unique expertise to create breakthrough solutions in material science.

However, magnetic materials research is
Ultra-high-grade neodymium‑iron‑boron (Nd-Fe-B) magnets are essential components of clean energy technologies, including electric vehicles and wind turbines. However, they often contain dysprosium (Dy), a heavy rare earth whose extraction poses environmental, social and supply risks. Dysprosium is often used in high-performance magnets because of its ability to maintain their magnetic
GREENE research partners have shown that the answer may be yes. By combining a recycling route that preserves the original microstructure with in-situ grain-boundary diffusion, they produced recycled Nd-Fe-B magnets with a coercivity 13% higher than that of the starting material.
