Denka accurately grasps the environmental burden substances emitted from the production facilities of group companies and is engaged in ongoing reduction efforts. The target substances include greenhouse gases such as CO2, SOx (sulfur oxides), NOx (nitrogen oxides), particulates, BOD (biochemical oxygen demand), COD (chemical oxygen demand), as well as substances designated by the PRTR system (Pollutant Release and Transfer Register). In addition, in response to the social issue of marine plastic waste, we are also focusing on the initiatives for reducing plastic waste emissions and recycling established by the Plastic Resource Circulation Promotion Law, which came into effect in April 2022.
We are actively introducing removal devices for environmental burden substances, and complying with self-imposed standards that are stricter than relevant laws and regulations, and will continue to strive to reduce the emission of environmental burden substances.
Consideration for the Global EnvironmentDenka is committed to global environmental preservation based on Responsible Care, an initiative promoted by the global chemical industry. As a responsible chemical manufacturer, Denka will continue to address the issues of global environmental preservation.
