SIM² KU Leuven designs, researches and exploits selective and efficient processes for the exploration, extraction, recovery, recycling and refining of (base and critical) metals and minerals, as well as for the upcycling of primary and secondary resources.
SIM² KU Leuven targets both primary ores, extractive waste, industrial process residues and urban solid waste. Key focus areas are (1) metal extraction from increasingly complex, polymetallic, low-grade ores; (2) metal recovery from stocks of extractive waste (incl. tailings) and landfilled industrial process residues (e.g. sludges, dusts, slags…); (3) metal recovery from flows of industrial process residues from primary and secondary metal production; (4) direct (preconsumer) recycling of metal scrap and swarf generated during the production of metal-based (intermediate) products; (5) (postconsumer) recycling and/or urban mining of, respectively, flows and stocks of complex, multi-material, metal-containing products (e.g. End-of-Life Hybrid Electric Vehicles) as well as construction and demolition waste); and finally (6) landfill mining of historic urban solid waste. SIM² KU Leuven targets a near-zero-waste vision, which implies that any kind of residual mineral matrices are upcycled into added-value materials such as inorganic polymer binders and derived engineered products. Hazardous components are concentrated into specific phases that can be safely stored. As such SIM² KU Leuven’s research and education programme directly contributes to the circular economy vision and supports the transition to a low-carbon economy.
