Sustainability as a fundamental principle

H.C. Starck Tungsten Powders follows a holistic concept of sustainability that extends from raw material extraction and supply chains to production facilities and processes and occupational health and safety. As a company in the metallurgy industry, we attach particular importance to the origin of the primary raw materials we use to supplement the secondary materials obtained from recycling. We are founding members of the Tungsten Industries – Conflict Minerals Council (Tl – CMC) and members of the ITRI Tin Supply Chain Initiative (iTSCi) and the Responsible Minerals Initiative (RMI).

We take responsibility
