  1. 21. End-Of-Life Wind Turbines in the EU : An Estimation of the NdFeB-Magnets and Containing Rare Earth Elements in the Anthropogenic Stock of Germany and Denmark

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Lisa Welzel; [2019]
    Keywords : rare earth elements; neodymium; dysprosium; wind turbines; permanent magnets; recycling; recovery; closing the loop; urban mining; sustainability; sällsynta jordartsmetaller; neodymium; dysprosium; vindturbiner; permanenta magneter; återvinning; cirkulärt system; hållbarhet;

    Abstract : Securing rare earth elements (REE) for a stable supply require sustainable management strategies in Europe due to a missing local primary production and a dependence on China as the main producer of REE. These elements, like neodymium (Nd) and dysprosium (Dy), are contained in permanent magnets (PM) (mostly NdFeB-magnets) in wind turbines. READ MORE
