Recycling

For many years, we have conducted research and development on the separation and refining technologies required for metal recycling, as well as on battery materials. By combining these proprietary technologies to generate synergies, we have enabled the separation and refinement of nickel, cobalt, lithium, and other useful metals from used electric vehicle (EV) secondary batteries and used etching liquids (etchants) released during the printed circuit board manufacturing process.

This enables used secondary batteries and waste liquid that were previously treated as industrial waste to be reused as industrial resources. In addition, we are using this technological development as the basis to collaborate with various partners, aiming to reduce environmental impact and effectively utilize resources not only at Nihon Kagaku Sangyo itself, but also throughout our entire supply chain.
