Denka is properly managing the volume of environmental load substances emitted from production facilities and R&D bases run by its Group companies while continuously working to reduce the emission of such substances. In addition to managing its GHG emissions, the Group is striving to control emissions of sulfur oxide (Sox) and nitrogen oxide (NOx) from boilers and heating furnaces; substances emitted from production lines, including soot and dust; substances that affect biochemical oxygen demand (BOD) and chemical oxygen demand (COD); and substances regulated under the Pollutant Release and Transfer Register (PRTR) laws.
We strive to comply with relevant laws and national and municipal regulations as well as upholding pollution control agreements with local authorities. Having installed wastewater treatment facilities, bag filters and other equipment to remove harmful substances, we are enforcing voluntary emission standards that are even more stringent than those mentioned above in the course of facility operations and maintenance.
