Kyocera Corporation will build a new refining facility at one of its Japanese plants to recover tungsten carbide, the primary raw material used in cemented carbide, from used cutting tools. The facility is scheduled to begin operations in the company’s 2030 financial year. Japan’s Ministry of Economy, Trade and Industry has certified the initiative under its ‘Plan for Securing a Stable Supply of Critical Minerals’ programme. Through this initiative, Kyocera aims to secure a stable supply of tungsten, strengthen supply chain resilience and contribute to a resource-circulating society.
