Tungsten carbide and the environment

Environmental information from manufacturing and processing of tungsten carbide is available for the H. C. Starck plant in Germany (H. C. Starck, 2005).

The exhausts from manufacturing and processing are connected to exhaust filters. Thus, at H. C. StarcK during production virtually no tungsten carbide is emitted into the atmosphere, in 2003, according to the current Official Emission Declaration, virtually no tungsten carbide (< 25 kg/a) was emitted into the atmosphere (H. C. Starck, 2005).

The carburization of  tungsten or other precursors is virtually free of liquid water.
