Environmental Considerations ECO-PROCESS (The way we manufacture is “eco-friendly”) ■Recycling and Reuse of Resource: about 99% (of total by-products generated in steelworks is recycled) Recycling steel slag and dust Nearly all the steel slag, that makes up the majority of steel by-products is used as raw materials for cement, ground improvement material, road bed material, and so forth. This also helps natural resource conservation and energy conservation.Dust generated in the process of iron manufacture is processed by the “RHF” (rotary hearth furnace) equipment and to recover usable resources, thus establishing zero emission system for steel dust. Recycling of resources from plastics of containers and packaging waste Nippon Steel recovers 100% of resources (oil, coke, coke oven gas) from the container and packaging plastics collected by individual local governments from ordinary homes. At present, Nippon Steel has established the world's largest, waste-plastics reception network by which its seven areas of five steelworks in nationwide locations are servicing the entire country. Nippon Steel recycles about 30% (200,000 tons) of the container and packaging plastic collected from municipalities throughout Japan, and has processed a total of 3.27 million tons (between 2000 and 2019). This is equivalent to a total CO2 reduction of approximately 10.5 million tons. In addition, the company also recycles fiber products including discarded uniforms and food trays from store front collection in cooperation with tray producing companies into petrochemical products, using our above-mentioned technology. Recycling of resources from waste tire Setouchi Works Hirohata area recycles waste tires gathered from all over the country. In resource recovery, waste tires are used as raw materials and fuel by the Scrap Melting Process (SMP) for iron manufacture and thermal cracking by the gasification recycling equipment. (This operation was stopped at the end of March 2020.) ■Energy Recycling: about 81% (of the total power generation in steelworks is generated from recovered waste heat and by-product gas) Electric power generation through recovered waste heat and by-product gases Nippon Steel Group recovers high-temperature waste heat and 100% of by-product gas generated in coke ovens, blast furnaces, converters, and so on, and efficiently uses them as electric power. 81% of the total electric generation in steelworks is generated from the recovered waste heat and by-product gases. CDQ (Coke Dry Quenching) By introducing CDQ (a power generation system using recovered waste heat), a major-scale CO2 reduction has been realized. ■Water Circulation: about 90% achieved About 90% of the water used for cooling and cleaning products and manufacturing equipment is being re-circulated. ■Bio-mass from residual wood from the thinning of mountain forest, bio-mass from coffee grounds East Nippon Works Kashima area and Kyushu Works Oita area are using such wood chips and non-commercial-grade timber for a coal-fired thermal power station. Mixing woody bio-mass with coal for combustion can serve the purpose of using less coal, which is a fossil fuel Japan imports, and thus reduce CO2 emissions, while also helping to forest management. East Nippon Works Kashima area is making the similar effort by using coffee grounds. --> Prev Next Page top Lang : JP EN 中文 Products Use application Six strengths --> News and events Downloads Contact Us Research & Development Overview of R&D Laboratories Technical Papers and Technical Reports About Nippon Steel Who we are Offices Manufacturing Bases Investors IR News Management Plan Financial Information IR Library Stock & Corporate Bonds To Our Shareholders Investor FAQs IR Calendar Terms & Conditions Sustainability Environment Social Governance Copyright NIPPON STEEL CORPORATION.
