Benin: France-based Chovet is reportedly preparing to support the construction of a 2Mt/yr integrated cement plant. Preparatory studies have been completed and construction is ready to start, according to 24 Heures au Bénin. The engineering company will be responsible for supervising all work, providing project management assistance and monitoring the quality of the installed infrastructure. The project was originally mandated at a meeting of the government’s Council of Ministers in late 2022.

Bangladesh: The Bangladesh Cement Manufacturers Association (BCMA) has requested that the National Board of Revenue (NBR) lower an import tax on clinker to US$1.7/t. The lobbying is taking place ahead of the upcoming budget for the 2025 – 2026 financial year, according to the Financial Express newspaper. The association also expressed concern that a 10% duty was levied on limestone imports, but it expects this to be relaxed in the upcoming budget. The BCMA has urged the NBR to simplify customs regulations and impose a tariff system on value-added tax (VAT) calculations.

Vietnam: The Ministry of Construction has reported a cement surplus to the Prime Minister, blaming a supply-demand imbalance. The country has 92 cement production lines with a capacity of over 122Mt/yr, according to the Việt Nam News newspaper. However, cement and clinker consumption was 95Mt in 2024, with 65Mt used domestically and 30Mt exported.

Planning regulations governing cement plants were relaxed in 2017. Subsequently, local authorities approved 13 new units that added 35Mt/yr in capacity. The Ministry of Construction proposed a national building materials strategy capping total cement production at 125Mt/yr by 2025 and 150Mt/yr by 2030. The ministry has also urged provincial governments to limit new cement projects to prevent excessive supply. It has proposed tightening the planning laws on building new cement plants.

The Vietnam National Cement Association (VNCA) has highlighted weak market demand and production constraints as major challenges to the sector. It has lobbied the government to promote housing, infrastructure and road projects to grow the cement market.

UBE Mitsubishi Cement recently released an update on its commercial scale demonstration using ammonia as a fuel at its Ube plant. It is currently testing the use of ammonia in both the cement kiln and calciner at the site. It has set the aim of reaching a 30% coal substitution rate with ammonia in the cement kiln by the end of March 2025. It has described the project as a world first. Planned future work includes running ammonia combustion tests alongside post-consumer plastics.

The company announced the three-year project in mid-2023. Utilities company Chubu Electric Power has been working on it and UBE Corporation has been supplying the ammonia for the test. The scheme dates back to before Mitsubishi Materials and Ube Industries merged their cement businesses in 2022. Ube Industries previously took part in a government research project looking at the topic, running combustion tests and numerical analysis in small industrial furnaces.

Another ammonia research project in the cement sector was revealed in 2024 by Heidelberg Materials in the UK. The company was awarded just under €0.40m in funding by Innovate UK through its UK Research and Innovation (UKRI) fund, together with engineering consultants Stopford and Cranfield University. The 12-month feasibility study aimed to assess the use of ammonia as a hydrogen carrier and evaluate the most economical method of on-site ammonia cracking to generate hydrogen for use by clinker kilns. It also intended to investigate the various tiers of the UK's existing ammonia supply chain network for the suitable transportation, offloading and storage of ammonia.

The UK project explained that it was looking at ammonia as a hydrogen carrier due to its high volumetric energy density. This, potentially, makes ammonia easier and cheaper to store and transport than hydrogen. It pointed out that storing and transporting hydrogen is difficult and the chemical is expensive. It also noted that the volumetric energy density of ammonia is 45% higher than that of liquid hydrogen. The benefit of switching to a zero-carbon fuel was that it could cut CO₂ emissions by the cement and concrete sector in the UK by 16%.

The attraction of ammonia to the cement industry is similar to that of hydrogen. Both are versatile chemicals that can be produced and used in a variety of ways. The production processes and supply chains of both chemicals are linked. The Haber–Bosch process, for example, uses hydrogen to manufacture ammonia. It can also be cracked to release the hydrogen. When used as fuels neither release CO₂ emissions directly. This comes down to the method of production. Like hydrogen, there is a similar informal colour scheme indicating carbon intensity (Grey, Blue, Green and Turquoise). Despite the advantages listed above, the disadvantages of using ammonia include toxicity and NO_x emissions, as well as the fact that there is little experience of using ammonia as a fuel. The worldwide ammonia market was bigger by volume in 2023 with production of just under 200Mt compared to hydrogen production of just under 100Mt.

Back in Japan, the national government has been promoting the use of ammonia technology for the power generation sector. It added ammonia to the country’s national energy plan in the early 2020s following research on running power plants with a mixture of ammonia and coal. The ambition is to build up levels of ammonia co-firing at power plants, develop the necessary technology and grow supply chains. This, it is hoped, will broaden, diversify and decarbonise the domestic energy mix and pull together a new international market too. Unfortunately, this strategy has had criticism. One study by BloombergNEF in 2022 estimated, for example, that the electricity cost of Japan-based power stations switching to firing ammonia by 2050 would be more expensive than generation from renewables such as solar or wind.

This explains why the ammonia project by UBE Mitsubishi Cement is leading the way. The interest by a European cement company shows that others are thinking the same way too. Yet again, the potential decarbonisation solution for cement is likely to lead towards more complex industrial supply chains. The next steps to watch will be whether a cement plant in Japan actually starts to co-fire ammonia on a regular basis and if any more ammonia projects pop up elsewhere around the world.

Oman: Raysut Cement has appointed Jamal Shamis Saud Al Hooti as its chair. Khalid Masoud Ansari has been appointed as the vice chair and Liyutha Mohamed Sulaiman Al Ismaili has been appointed as the secretary of the board.

Finland: Tana Oy has appointed Jari Mennala as its CEO with effect from 5 May 2025. He succeeds Kalle Saarimaa who became the Chief Operating Officer and Executive Vice President of NG Group in February 2025.

Mennala was appointed as the Director of Worldwide Forestry Sales & Marketing and Managing Director of John Deere Forestry Oy in 2024. He has worked for John Deere since 2008 for its forestry division in Finland, the US and the UK. He holds a master’s degree in industrial management from Tampere University of Technology and an executive master’s of business administration from Aalto University in Helsinki.

Cameroon: Cameroon will increase its cement production capacity by 4.3Mt to 12.7Mt/yr by the end of 2025 with the addition of three new plants in Édéa, according to Business in Cameroon. The new facilities will help meet local demand and support exports.

The first plant, Sino Africaine (Sinafcim) is under construction and will have a 1Mt/yr capacity. It is set to begin production in April 2025. It will employ 200 workers and 90% will be Cameroonian. The second, Central Africa Cement (CAC), has been operational for several months with a 1.5Mt/yr capacity. It currently employs 100 people and aims to reach 200. The third, Yousheng Cement, is being built near Douala and will have a 1.8Mt/yr capacity. National demand in Cameroon is reportedly around 8Mt.

India: The Competition Commission of India has approved Ambuja Cements’ acquisition of Orient Cement, months after the Adani Group company announced the US$451m deal, according to The Economic Times.

Ambuja Cements first revealed plans to acquire Orient Cement in October 2024, intensifying its competition with rival UltraTech Cement.

The Indian cement sector has seen increased competition recently, with both UltraTech and Adani Group companies acquiring smaller firms to expand market share. Analysts had questioned whether the acquisition would secure regulatory approval due to industry oversupply concerns.

India: UltraTech Cement has increased its production capacity by 1.2Mt/yr through debottlenecking efforts. The producer said that it had identified multiple efficiency enhancement opportunities across various locations as part of its capacity expansion programmes. The additional capacity includes 0.8Mt/yr at the integrated Hirmi plant in Chhattisgarh and 0.4Mt/yr at the Roorkee grinding unit in Uttarakhand. Ultratech’s domestic cement capacity now reportedly stands at 179Mt/yr.

Spain: Cement consumption rose by 9% year-in-year in February 2025 to 1.27Mt, around 100,000t more than in February 2024, according to the latest statistics from Oficemen. Consumption for the first two months of 2025 reached 2.40Mt, up by 9%. In the 12 months to February 2025, total consumption rose by 4% to 15.1Mt.

“Although it is still early to make assessments, it is significant to note that last month was the February with the highest cement consumption since 2011, which confirms a certain continuity in the positive trend we experienced at the end of 2024 and which we expected to continue in 2025. Furthermore, our data is in line with other relevant indicators in the construction sector, whose performance is also positive, such as public tenders, which grew by 33.5% in January, and permits for new housing, which ultimately closed 2024 with 127,721 approved units,” said Oficemen general director Aniceto Zaragoza.

Exports fell by 15% to 0.3Mt in February 2025, a loss of 55,600t. In the 12 months to February 2025, exports fell by 5% to 4.80Mt.
