Denka strives to accurately gauge the volume of environmental load substances emitted from production facilities run by its Group companies while continuously working to reduce them. These substances include greenhouse gases, such as CO₂, SOx (sulfur oxides), NOx (nitrogen oxides), soot and dust, BOD (biochemical oxygen demand), COD (chemical oxygen demand), and other substances designated by the PRTR system (Pollutant Release and Transfer Register Law). With marine plastic waste becoming a social issue, we are also focusing our efforts on reducing and recycling plastic waste as stipulated in the Law for Promotion of Recycling of Plastic Resources, which came into force in April 2022.
We will actively introduce equipment to remove substances that have a negative environmental impact, comply with voluntary management standards that are stricter than those set by relevant laws and regulations, and continue to strive to reduce the amount of environmental load substances.
