Catalan Researchers Use Bacteria to Recover Smartphone Metals

Researchers at the Polytechnic University of Catalonia (UPC) have discovered a method for recovering copper, gold, aluminum, and platinum from discarded mobile phones by employing bacteria. The system is more efficient than melting PCBs and almost emissions free.

This idea entails using the metabolic activity of certain microorganisms (essentially bacteria) to regenerate the agents that are holding the metals in place and thereby unlocking them.
