Water quality survey: "COD emissions", "total nitrogen emissions in drainage", and "total phosphorus emissions" are not disclosed because the values are minimal. Since the Nippon Sanso group mainly uses these materials for indirect cooling, the burden on water quality is minor.
In Nippon Sanso and its subsidiaries in Japan, there are five establishments where wastewater is subject to COD, total nitrogen, and total phosphorus concentration regulations. The total COD, total nitrogen, and total phosphorus emissions from those five establishments are fewer than 1 ton each.
