Water Pollution Prevention in 2006
The volume of BOD emission was 4.1tons in FY2005, a 10% decrease compared to FY2005.
Each facility has set voluntary standards for harmful substances (such as Hexavalent chromium compounds and lead), and living environment items such as BOD (biochemical oxygen demand), that are more stringent than required by regulations for discharged water from manufacturing processes. Discharge to public water areas or sewage was carried out after appropriate treatment, and upon clearance of these voluntary standards.
