Examples of Activities

Reduction of Environmental Impact

  • NIPPON STEEL ENGINEERING Group perform periodical environmental audits at all of our work sites and plants / offices to confirm the status of compliance with environmental laws and regulations, and to make any necessary rectifications.
  • We ascertain the level of energy consumption at all of our plants and offices in Japan, and monitor our greenhouse gas emissions.
Energy usage※1
(Crude oil equivalent)
Greenhouse gas emissions※1 Water usage※2 Ratio of direct final disposal consisting of industrial waste※3
2017 1,736kl 3,724t 22,339m2 4.5%
2018 1,691kl 3,473t 22,496m2 16.5%

※1:The relevant sites are the Osaki Head Office, Kitakyushu Technology Center (KTC), branch offices, and other continuing business sites.
※2:Combined total value for the Osaki Head Office and KTC (Increase in FY2019 due to relocation of the institutes to KTC)
※3: Varies according to the contents of ordered work (Increase in FY2019 due to inclusion of removal/disposal of existing equipment)


※1:Environmental contribution products/coke dry-quenching (CDQ), waste-to-energy plants, geothermal power generation equipment, cogeneration equipment, sewage sludge fuelization system (J-Combi®), and wind-power equipment in the steel manufacturing process.

※2:The figures in the graph indicate the CO2 reduction effect values obtained by using the emissions coefficient, etc., of domestic power to estimate the amount of electric power produced by environmental contribution products built by Nippon Steel Engineering in Japan and overseas up to FY2019, based on the assumption of an operating rate that takes into consideration the traits of each facility, etc.
