Technology for Recovering Valuable Metals from Urban Mines and Unutilized Resources

「As part of the effective use of unused resources, we are developing a process to recover precious metals such as gold and silver from geothermal water, while also focusing on recycling critical minerals, for which demand is expected to grow.」

「To enable the effective use of “urban mines” (recovering and reusing metal materials from used home appliances, mobile phones and other products) and unused resources, we are developing technologies to recover valuable metals using environmentally friendly adsorbents derived from microorganisms. In the urban mining field, we are working to further recover precious metals from spent automotive catalysts, which contain large amounts of high-value raw materials; developing methods to remove arsenic and other toxic metals from sludge and similar materials previously treated as waste and convert them into valuable products; and developing recycling methods for lithium-ion batteries (LIBs), which are expected to face waste-related challenges in the future.」
