Metal recycling needs to become more cost-efficient because it is a crucial contributor to the global circular economy and the transition to renewable energy. Typically, only 1% of the most important metals — notably rare metals — are recycled (see, for example, Y. Geng et al. Nature 619, 248–251; 2023). Better and more effective systems are needed to identify, sort, trade and transport these end-of-life materials. Artificial intelligence (AI) could help.
