An international team of the EU project Passenger has just published a LCA study on ferrite and MnAlC permanent magnets. The work of Amato et al. is titled “Life Cycle Assessment of Rare Earth Elements-Free Permanent Magnet Alternatives: Sintered Ferrite and Mn−Al−C” was published in ACS Sustainable Chem. Eng. 2023, 11, 13374−13386. https://doi.org/10.1021/acssuschemeng.3c02984
The possible substitution advantage of these compounds is widely discussed in literature considering both magnetic properties and economic aspects. To evaluate further sustainability aspects, the present paper gives a life cycle assessment quantifying the environmental gain resulting from the production of RE-free magnets based on traditional hexaferrite and Mn−Al−C.
