Development and Growth of the Environment and Energy Business

「Since January 2024, we have installed gas boiler equipment at our Kumagaya Plant, our main plant, and have also completed installations at the Amagasaki and Mie plants. Previously, we used energy generated by heavy-oil-fired boilers in the curing process that accelerates concrete hardening. By switching to gas boiler equipment, we can manufacture products while reducing CO2 emissions from the equipment by approximately 33%.」

「・ To promote the adoption of low-carbon, high-performance concrete "e-CON," the e-CON Association was established, with 28 companies nationwide participating.」

「e-CON® not only significantly reduces CO2 emissions during manufacturing, but also offers excellent durability, reducing the environmental impact over its entire life cycle by extending product life. In January 2025, we established the e-CON Association to promote its adoption and facilitate technological collaboration.」

「e-CON® is a long-life concrete material that contributes to reducing CO2 emissions and offers excellent resistance to salt damage and acids. Going forward, the entire company will work together to commercialize and expand sales of the product and contribute to achieving a decarbonized society.」

「③ Solar Power Generation and Real Estate Business Net sales were ¥1,150 million, up 3.4% year on year, and operating profit was ¥613 million, up 1.1%. The solar power generation business secured revenue at approximately the same level as in the previous year’s corresponding period.」

「With regard to ESG management, as a measure to reduce CO2 emissions, we began upgrading the boiler equipment at our main plant, the Kumagaya Plant, to reduce greenhouse gas emissions. The upgrade is scheduled for completion in January 2024 and is expected to contribute to a 30% reduction in CO2 emissions at the Kumagaya Plant.」

「The group regards the 100th anniversary of its founding in 2025 as a milestone and is advancing the medium-term management plan, the “23-27 Plan R,” positioning the 5-year period from fiscal 2023 through fiscal 2027 as a “period of reform” in order to create a growth trajectory toward becoming a 200-year company. Through investment in human resources, R&D investment, and capital investment for the carbon-neutral era,」

「As initiatives toward a decarbonized society, we advanced research on CO2 sequestration for carbon-neutral concrete products and basic research toward applying special concrete to wind-power-generation facilities.」

「Function enhancement and demonstration testing of the low-carbon concrete “e-CON®” toward achieving carbon neutrality」

「The company completed development of the vertical storage tank “Wellman Storage Tank” for urban flood control, introduced the next-generation DX construction-management system “Pile-ViMSys® (パイルヴィムシス)” at actual construction sites, and added functions. It also advanced research to enhance the functionality of “e-CON®,” a CO2-reducing material for the carbon-neutral era.」

「In addition to advancing R&D on products that contribute to environmental sustainability and the realization of a decarbonized, carbon-neutral society, the company expanded its lineup of high-value-added products for rainwater management in response to climate change.」

「We are advancing research and development of environmental materials for a decarbonized society and products addressing stormwater management. We will continue to advance our medium- to long-term growth strategy based on “green and digital.”」
