Japan: Taiheiyo Cement reported net sales of US$2.84bn for the six months ending 30 September 2025, a 1% decline year-on-year. Operating profit fell by 10% to US$213m, while ordinary profit dropped by 7% to US$213m. For the full financial year ending 31 March 2026, the company forecasts net sales of US$5.87bn and an operating profit of US$453m.

There have been a few sustainability-related news stories to note recently in Japan. Firstly, the Renewable Energy Institute (REI) released a report on decarbonisation pathways for the cement industry. Then, this week, the Japan Cement Association (JCA) held a press briefing on the sector’s work towards net zero and it released production and sales data. Finally, on a connected note, a speaker from Sumitomo Osaka Cement gave a presentation on recycling gypsum wallboard for cement production at last week’s Global Gypsum Conference.

The REI’s report is similar to other roadmaps published by cement associations around the world. The differences with the Global Cement and Concrete Association (GCCA) targets are worth pointing out though. The JCA is more conservative on the use of blended cements. It only specifies an aggregate CO₂ reduction target for 2030, limited to a greater use of alternative fuels (AF) and improved energy efficiency. Similarly, it forecasts clinker factors of 0.825 in 2030 and 0.80 in 2050, compared to the GCCA targets of 0.58 in 2030 and 0.52 in 2050. The report goes on to show that JCA members have higher Scope 1 and 2 emissions and a higher clinker factor than comparable multinationals, including Holcim, Heidelberg Materials and SCG. In summary the REI concludes that the local sector has been delayed in adopting blended cements, slow on using more renewable energy and continues to be reliant on coal.

The JCA’s update is more practical and outlines what can be expected. A benchmarking system for the sector was established in the 2025 financial year. The country’s emissions trading scheme will then start in the 2026 financial year. Companies that emit a three-year average of over 100,000t/yr of CO₂ will be subject to the scheme. The JCA is currently emphasising the sector’s role at the heart of the circular economy. It pointed out that it used just under 22Mt (5%) of the country’s total waste in 2024. It had an AF substitution rate of 27% in that year also. Other waste streams used included over 5Mt of blast furnace slag, over 6Mt of coal ash and around 1.7Mt of flue-gas desulphurisation (FGD) gypsum.

That last one ties into a presentation that Yuki Mihashi, Sumitomo Osaka Cement, gave at the recent Global Gypsum Conference, held last week in the Netherlands. He gave an overview of his company’s pilot testing of a carbon capture and utilisation process that uses waste gypsum wallboard and mineralises it to make an artificial limestone from cement plant CO₂ emissions. The current pilot plant is based in Osaka and was completed in June 2025. It consumes 10kg/hr of gypsum and can produce around 5.8kg/hr of calcium carbonate. Gypsum wallboard professionals at the event had previously expressed concerns about competition for raw materials from cement producers. If developments like this one progress to full scale deployment there could potential be repercussions in other industrial sectors.

Finally, the latest data from the JCA shows that cement production fell by 3% year-on-year to 32.99Mt in the first nine months of 2025 from 34Mt in the same period in 2024 . Overall sales followed a similar trend, although exports rose by 9% from 5.91Mt to 6.43Mt. This follows a general decline in cement production in Japan since the mid-1990s.

In summary, work on sustainability in the cement sector continues in Japan as it does elsewhere. The conservative approach to clinker factor forecasts is interesting to note compared to more optimistic projections elsewhere. A slower update of blended cements may explain some of this. Interestingly, Taiheiyo Cement said in June 2025 that it was expanding a hub in Saiki to export blended cements rather than using them domestically. On other issues, a current lower AF substitution rate compared to Europe offers one pathway for emissions reduction. The impending ETS may also galvanise action and investment. Expect plenty more sustainability news in the coming weeks ahead of the 30th Conference of the Parties (COP), which is set to take place in mid-November 2025 in Belém, Brazil.

Indonesia: PT Solusi Bangun Indonesia (SBI) is developing a pier and cement production facility at its Tuban plant, East Java, to export up to 1Mt/yr to the US in collaboration with Taiheiyo Cement, according to national news agency Antara.

Corporate communications manager Novi Maryanti said that the project was a priority amidst the contraction of the domestic cement market. Maryanti said “With our large export capacity, we are optimistic that we can maintain the company's profitability and expand our contribution to the national economy.”

SBI, 83.5% owned by SIG, operates four plants in Narogong, Cilacap, Tuban and Lhoknga with a combined capacity of 14.8Mt/yr and more than 2000 staff.

Japan: Taiheiyo Cement says it started using an artificial intelligence-based (AI) ship allocation optimisation system in May 2025. Software company Grid provided the technology for the project. The companies say that this is the first such application in the domestic cement industry.

The new ship allocation system analyses large volumess of transportation data and generates optimal ship allocation plans while considering various constraints. It is intended to: reduce transportation costs such as fuel; optimise courses and loading efficiency, with an expected 10% reduction of fuel consumption at the planning stage; enhance inventory management; and reduce planning time by more than 50% compared to manual planning methods.

Sri Lanka: KPN Cement Lanka has launched a fly ash cement product in conjunction with Japan-based Taiheiyo Cement. The product, called Taishi Cement, will be available for large-scale infrastructure projects, real estate developments and government initiatives, according to the Daily Financial Times newspaper. KPN Cement Lanka and Taiheiyo Cement are also intending to promote an awareness programme for sustainable construction practices in the country.

Taiheiyo Cement launched an export hub for blended cements in June 2025 called the Saiki Ash Center in Saiki City, Oita Prefecture. The site is intended to export fly ash-based blended cement products to Southeast Asia. It has an export capacity 0.8Mt/yr.

Japan: Taiheiyo Cement has announced that it will expand the export of blended cement through the establishment of a new facility at its Saiki Ash Centre in Saiki City, Oita Prefecture. Taiheiyo Cement says that the facility, which will meet growing demand for blended cement in South East Asia, is part of its sustainability strategy. The blended cement will use fly ash from domestic coal-fired power plants.

The new facility will expand Taiheiyo Cement’s blended cement export capacity from 0.8Mt/yr to 1.3Mt/yr.

Philippines: The Department of Trade and Industry (DTI) has announced that Taiheiyo Cement’s US$67m Luzon Distribution Terminal, which will supply up to 0.7Mt/yr of cement to Luzon, will begin operations in early 2026. The plant will use a high proportion of supplementary cementitious materials (SCM), including fly ash, slags and natural pozzolans.

Taiheiyo Cement has said that the terminal represents the Japan-based company’s long-term commitment to the Philippine cement market and that it is aware of recent DTI rules that aim to safeguard domestic cement producers.

Japan: Taiheiyo Cement recorded net sales of US$4.4bn, up by 3% year-on-year, from 1 April 2024 to December 2024. Sales were US$4.3bn in the corresponding period of 2023.

The company’s financial report stated “During the nine months ended 31 December 2024, the Japanese economy showed a moderate recovery trend, partly due to the effect of various government policies under an improving employment and income situation. However, the outlook remained uncertain due to factors such as the protracted situation in Ukraine and continued yen depreciation.”

It also stated that domestic cement demand was affected by multiple factors, such as a labour shortage, the adoption of a five-day week for the construction industry and a shortage of lightweight aggregates. It reported that demand decreased 6% year-on-year to 25.15Mt, of which imported cement increased 26% year-on-year to 10,000t. Total exports increased by 25% year-on-year to 6.24Mt. The group’s domestic cement sales volume decreased by 5% year-on-year to 9.52Mt, with exports increasing by 22% to 2.4Mt. Its cement businesses in US, Vietnam and the Philippines all also saw a decrease in sales volumes.

Japan: Taiheiyo Cement has reported net sales of US$2.86bn for the six months that ended on 30 September 2024, a 5.5% increase compared to US$2.71bn a year earlier. However, the company’s operating profit for the six-month period was US$115m, a decrease of more than 50% compared to US$325m in the first six months of the prior financial year.

Japan: Taiheiyo Cement, ITOCHU, Nippon Steel, Mitsubishi Heavy Industries, INPEX, Taisei, and ITOCHU Oil Exploration have been chosen by the Japan Organisation for Metals and Energy Security (JOGMEC) to lead the engineering design work for key carbon capture and storage (CCS) initiatives. This selection marks a step towards Japan's ambitious goals to achieve carbon neutrality by 2050 and a 46% reduction in greenhouse gas emissions from financial year 2013 (FY13) levels by FY30.

The project encompasses front end engineering design (FEED) and appraisal drilling as critical next steps following a comprehensive feasibility study conducted in FY23. This prior study involved detailed assessments of CO₂ separation, capture, transportation and storage processes. The CCS initiative involves shipping CO₂ captured at Nippon Steel’s Kyushu Works in the Oita area and Daiichi Cement's Kawasaki plant, part of the Taiheiyo Cement Group, to designated storage sites.
