Curtailing Emissions of Chemical Substances in Exhaust

Management of Compliance with Regulatory Values

The Oji Group owns a number of thermal-fired electric power generating plants. The electric power and thermal energy obtained through direct combustion of fossil fuels, waste fuels, and renewable fuels is used internally and provided to local communities.
The Group has set voluntary management values that are stricter than the regulatory values with regard to the atmospheric release of the chemical substances produced through direct combustion. In cases where voluntary standards are over, suspension of operations and other measures are taken for the prevention of pollution.

Status of Reductions in Chemical Substances in Exhaust

We are working to reduce emissions of VOC (volatile organic compounds) to maintain them at or below their levels in FY2010, which is a guideline presented by the Japan Paper Association. In addition, we are also operating according to voluntary control values for SOx (sulfur oxides).
