Popis: Permanent magnets (PM) are critical constituents of many technological applications, especially in the context of modern environmental policies to improve energy efficiency and develop digital economy. Modern PMs rely heavily on rare earth elements (REE), raw materials of geopolitical and strategic importance which are used in a wide range of products. In this work, we present a study of the current state of availability of REE and its future trends. For the period 2017–2030, our analysis suggests that with the existing PM technology, gradual replacement of conventional passenger cars’ production by hybrid (HV), plug-in hybrid (PHV) or electric (EV) along with electric bikes, wind turbines and robotics will require a total increase of 191% in Nd and 168% in Dy supplies, respectively. These quantities may not be economically feasible to be available. A future prospect of recycling from end-of-life (EOL) products should be considered.
