Rare earths, electronic waste, recovery, circular economy.
Abstract
Current technologies depend on little-known but essential elements: rare earths. Although they are not scarce on Earth, their extraction is complex and polluting. These elements are used in screens, electric vehicles, medicine, and more. However, their demand is growing and resources are being depleted, which is why their recovery from electronic waste is being sought through different methods such as acid leaching, pyrometallurgy, or more environmentally friendly techniques. Recycling rare earths not only reduces environmental impact, it also boosts access to clean technologies and paves the way for a circular and sustainable economy.
