Achieving 20% Energy and Electricity Savings

「We continued steady improvements in yield and energy intensity centered on shop-floor activities and carried out planned capital investments at each site, including starting operations at the energy-saving, low-CO2 electric furnace at the Sakai Plant in February this year.」

「For the installation of the energy-saving, low-CO2 electric furnace at the Sakai Plant, we reviewed the construction period in light of adjustments to the construction schedule and other factors and are working toward starting operations within the current fiscal year. We are also carrying out planned replacement investments for aging equipment, including crane replacement at the Kumamoto Plant.」

「We continued steady improvements in yield and energy intensity centered on shop-floor activities and carried out planned capital investments at each site, including starting the main construction work for the energy-saving, low-CO2 electric furnace at the Sakai Plant, scheduled for completion in 2025, and completing the new product warehouse at the West Japan Kumamoto Plant.」

「Regarding capital investment, foundation work has begun on the energy-saving, low-CO2 electric furnace at the Sakai Plant, for which a decision was made last fiscal year and completion is scheduled for fiscal 2025. The product warehouse at the West Japan Kumamoto Plant was completed in July this year, and we are improving truck drivers' working conditions by shortening loading times. Investment plans are progressing as scheduled.」

「We continued steady improvements in yield and energy intensity centered on shop-floor activities, while benefiting from improvements generated by capital investments such as the rolling-line extension work at the Kishiwada Plant and the installation of flue-gas analysis equipment at 東京鋼鐵, thereby working to contain the impact of rising energy and commodity prices. During the period, we also worked to strengthen our business platform for the future, including deciding to install an energy-saving, low-CO2 electric furnace at the Sakai Plant, build a new product warehouse and expand solar power generation facilities at the Kumamoto Plant, and transfer rail-processing equipment at the Onが島 Plant.」

「During the first half of the fiscal year, we improved yield and energy intensity through the effects of the rolling-line extension work at our Kishiwada Plant carried out last fiscal year and the investment in flue-gas analysis equipment at Group company 東京鋼鐵. We also continued to develop the systems infrastructure needed to further strengthen quality control. With regard to establishing our business platform, following the consolidation of plants and optimization of fixed costs through the rolling-line reinforcement project at the Osaka Operations Office completed last fiscal year, we decided in August this year to install an energy-saving, low-CO2 electric furnace at the Sakai Plant of the Osaka Operations Office. We are working toward starting operations in 2025 while significantly improving variable costs, particularly energy costs, and reducing CO2 emissions.」

「In addition to strengthening the cost competitiveness of each site through initiatives such as starting investments at the Kishiwada Plant that will improve costs and energy efficiency and transferring production of certain products from our Sakai Plant to 東京鋼鐵, we are also working to establish an optimal production structure across the Group.」

「Construction work to strengthen the rolling line at the Osaka Operations Office was completed in fiscal 2020, and certification and approval for major product types were completed in fiscal 2021. As commercial production began, we worked to improve the direct-delivery rate of hot billets from steelmaking to rolling as a result of production consolidation, and energy-saving effects have also begun to emerge.」

「On 28 April this year, we formulated and announced the OSAKA STEEL CO.,LTD. Group Medium-Term Management Plan, whose primary objective is to contribute to society by contributing to a circular and decarbonized society through steel recycling using electric furnaces and, as a top supplier, further strengthening our manufacturing capabilities and cost and quality competitiveness so that we can supply products that meet customer needs.」

「In addition to further strengthening quality and product competitiveness and pursuing energy and power conservation, we have actively promoted measures to ensure thorough compliance, recruit and train personnel capable of supporting sustainable business development, pass on skills, and strengthen the foundations for safety, health, environmental and disaster-prevention measures. We have also actively pursued thorough cost reductions through operational efforts rooted in the shop floor and actual conditions.」

「To further pursue energy and power conservation, we installed equipment at the Sakai Plant of the Osaka Operations Office to improve the stirring capacity of molten steel in the electric furnace, as well as multifunctional burners and other equipment at the West Japan Kumamoto Plant.」

「We have also worked to further pursue energy-efficient and resource-saving operations and to achieve thorough cost reductions through operational efforts rooted in the shop floor and actual conditions.」

「We have also worked to further pursue energy-efficient and resource-saving operations and to achieve thorough cost reductions through operational efforts rooted in the shop floor and actual conditions.」

「Amid this business environment, the Group has strengthened safety, health, environmental and disaster-prevention risk management while enhancing and reinforcing compliance, and has further strengthened quality and product competitiveness. We have also pursued greater energy and power conservation and thorough cost reductions through operational efforts rooted in the shop floor and actual conditions.」

「We will continue to pursue thorough energy-saving and productivity improvement measures and work to further strengthen our cost competitiveness, which is among the highest in the industry.」

「We have also worked to reduce costs in response to changes in the external environment, including the pursuit of more energy-efficient and resource-saving operations.」
