Water Use and Prevention of Water Pollution

Our main production base, the Iwaki Factory, also accounts for the majority of our water use. At the Iwaki Factory, we comply with the emission standards set by the Water Pollution Prevention Act and local ordinances. We have reduced our chemical oxygen demand (COD) by over 50% and our biochemical oxygen demand (BOD) by over 80% since fiscal 1995. At each of our manufacturing plants, we are working to reduce our environmental footprint by making a daily effort to maintain stable operation of wastewater treatment equipment. We are also working to ensure thorough wastewater management by making improvements to our machines and updating our water quality monitoring equipment.
At our Plastics Processing Factory (Ibaraki) located in Ibaraki Prefecture, we conduct monthly water quality inspections along with daily patrols and continuous pH monitoring of wastewater, in accordance with the emission standards ordained in the Water Pollution Prevention Act and local ordinances. At our Plastics Processing Factory (Hyogo), too, we carry out voluntary water quality analysis and continually conduct proper waste management. Since groundwater is pumped and used in industry in both districts, we also keep the amount of water collected within the limits set by the Industrial Water Act and local ordinances related to pumping groundwater.
