Abstract

Rare earth elements (REE) are currently essential enablers of the digital and decarbonization transition. However, their supply chain is highly concentrated and their extraction has a high environmental impact. Circular economy solutions could provide a double benefit, reducing supply risk for import-dependent countries and mitigating the impacts of REE mining.
