The Oji Group drains wastewater generated by business activities into various waterways after reducing environmentally hazardous substances in it to be below regulatory values by physical and chemical treatment.
When discharging wastewater, we measure the pollutant's quantity following the law and control them by continuous measurement. If the pollutant's quantity exceeds our voluntary control values, we take measures to prevent pollution by suspending operations.
We operate on voluntary management values that are stricter than the regulatory values to manage wastewater.
The COD emission reduction was approximately 48% compared to emissions of environmentally hazardous substances in line with the environmental regulatory values in FY2022.
