Emission Data of Production Facilities
The following is the data on exhaust gas and wastewater emissions as well as major chemical substance emissions or transfers from all works and plants of Kobe Steel and major group companies. The tables show numerical targets and actual emissions of exhaust gases (NOx, dust and dioxins) and major elements of wastewater from facilities such as chemical oxygen demand (COD) or biochemical oxygen demand (BOD), suspended solids (SS), oil and dioxins.

The emission data includes data from group companies, which are administered by Kobe Steel, operating on the premises of Kobe Steel's facilities.



Air Quality Data
* Numerical targets are based on the Air Pollution Control Law, prefectural government ordinances, and the Law Concerning Special Measures against Dioxins.
* Unit: ppm for NOx, mg/Nm3 for dust, and ng-TEQ/ Nm3 for dioxins
* Numerical targets are set separately for each facility.
* The following substances can be excluded from the tables because their emissions do not reach the quantitation limit or are less than the numerical targets:
SOx, cadmium, chlorine, hydrogen chloride, fluorine, hydrogen fluoride and silicon fluoride, lead, benzene, trichloroethylene, dioxin.


Water Quality Data
* Numerical targets are based on the Water Pollution Control Law, prefectural government ordinances, the Law Concerning Special Measures against Dioxins, the Sewage Water Law, and municipal government ordinances concerning sewage water.
* Unit: mg/l (pg-TEQ/l for dioxins)
* ND (Not detected): Below the quantitation limits
* The following substances are excluded from the tables because their emissions do not reach the quantitation limit or are less than the numerical targets:
pH, BOD, total nitrogen, total phosphorous, phenols, total chromium, soluble iron, soluble manganese, fluorine, copper, zinc, cadmium, total cyanide, organophosphorus compounds, lead, hexavalent chromium, arsenic, total mercury, alkyl mercury, PCB, trichloroethylene, tetrachloroethylene, dichloromethane, carbon tetrachloride, 1,2-dichloroethane, 1,1-dichloroethylene, cis-1,2-dichloroethylene, 1,1,1-trichloroethane, 1,1,2-trichloroethane, 1,3-dichloropropene, thiram, simazine, thiobencarb, benzene, selenium


Chemical substance
* unit: kg
