Ecocem announced this week that it has achieved certification in the US for its ACT low-carbon cement technology. This follows CRH’s agreement to buy US-based Eco Material Technologies, a supplier of supplementary cementitious materials (SCM), which was revealed in late July 2025. These moves and others mark a flurry of activity by various companies in the US SCM sector in recent months.

Donal O’Riain, the founder and managing director of Ireland-based Ecocem, underlined the importance of certification in North America when he said that “The US is one of the largest cement markets in the world, and this certification will support integration into existing supply chains and offers a pathway for the sector to rapidly decarbonise.” The country imported just under a fifth, 19Mt, of its Portland and blended cement in 2024 according to the United States Geological Survey (USGS).

Ecocem started out as a manufacturer of cements made using ground granulated blast furnace slag (GGBS), a SCM, in the early 2000s. Its ACT technology was formally announced in 2022. It is described as a process that can make cements using “available fillers like limestone and local SCMs.” It is currently scheduled for a commercial launch in 2026, starting in France. In the US it is planning to build a terminal and mill at the Port of Los Angeles in California. This follows a previous attempt to build a slag grinding plant, also in California, in the 2010s.

CRH, another cement company with strong links to Ireland incidentally, said on 29 July 2025 that it had agreed to acquire Eco Material for US$2.1bn. The latter operates a network of fly ash, pozzolan, synthetic gypsum and green cement operations. It partners with electricity generators to process about 7Mt/yr of fly ash and 3Mt/yr of synthetic gypsum and other materials. As CRH’s CEO Jim Mintern put it, “this transaction secures the long-term supply of critical materials for future growth and puts CRH at the forefront of the transition to next generation cement and concrete.” The deal is expected to close by the end of 2025. In separate comments to analysts Mintern added that he expects the market for SCMs to double in the US by 2050.

Other players have also been busy in recent months. Amrize, for example, noted in its financial results for the second quarter of 2025 that it had broken ground on a new fly ash beneficiation facility in Virginia in the reporting period. Last week, Graymont and Fortera signed an agreement to produce Fortera’s ReAct low-carbon cement product by using Graymont’s existing lime production operations. Fortera runs a plant in Redding, California that takes captured CO₂ from the adjacent CalPortland cement plant and uses it to manufacture its own proprietary SCM. Back in April 2025 Buzzi Unicem said that it had partnered with Queens Carbon to produce a novel cement and SCM. The start-up was intending to build a 2000t/yr demonstration plant at Buzzi Unicem’s cement plant in Stockertown, Pennsylvania.

The backdrop to all of this attention on SCMs in the US are the cost of cement and sustainability. Using more SCMs reduces clinker usage in cement and it can reduce the cost. At the same time reducing the amount of clinker used decreases the amount of CO₂ emissions. So, for example, Ecocem says that its ACT technology can reduce CO₂ emissions by up to 70% compared to conventional cement.

A report by Mckinsey on SCMs in the autumn of 2024 reckoned that growth in the cement market in North America was expected to be ‘robust’ in the next 15 years to 2050. However, the sector faces material, particularly clinker, and labour shortages. Enter SCMs! It went on to assert that much of the available stocks of GGBS and fly ash in the country are effectively used. Yet, traditional industrial SCMs such as GGBS, fly ash and limestone are anticipated to be available for longer than in Europe as industries such as steel manufacture and electricity generation will take longer to decarbonise. Hence companies such as Ecocem are preparing to import them, ones like CRH are cornering existing stocks and others such as Fortera and Queens Carbon are working on creating their own ‘virgin’ sources. At the same time the American Cement Association has been promoting the use of Portland Limestone Cement in the country.

All this helps to explain the interest in SCMs in the US right now. It’s a busy moment.

US: Ecocem has obtained ASTM C1157 certification for its ACT low-CO₂ cement technology, confirming it meets or exceeds strength and durability benchmarks while reducing emissions and energy use. Unlike traditional cement specifications, the standard is performance-based, allowing for innovative formulations.

Founder and group managing director Donal O’Riain said “This is a significant moment for Ecocem and for low-carbon cement globally. Over the past 10 years our solutions have seen significant traction across Europe. The US is one of the largest cement markets in the world, and this certification will support integration into existing supply chains and offers a pathway for the sector to rapidly decarbonise through improved efficiency and without increasing costs or complexity.”

Ecocem is advancing its first North American project, a proposed terminal and milling operation at the Port of Los Angeles, aimed at establishing a reliable low-CO₂ cement supply chain in California. The company says that its low-carbon cement technology, ACT, cuts clinker content by up to 70% by using limestone and locally-sourced supplementary cementitious materials. The announcement follows recent regulatory approvals in France, new investment in production lines in Dunkirk, and partnerships with Bouygues, Vinci and Titan Group.

France: Ireland-based Ecocem has obtained a Technical Evaluation of Products and Materials (ETPM) from the Centre Scientifique et Technique du Bâtiment (CSTB) for ACT1, the first iteration of its low-carbon cement technology. The ETPM certifies the mechanical performance and durability of concrete made with ACT1, confirming its compliance with European structural design codes.

The ETPM will support Ecocem’s planned submission for an Appréciation Technique d’Expérimentation (ATEx) in the second half of 2025, which will assess the use of ACT1 in structural applications such as walls, beams and foundations.

Director of product development and standardisation Christian Clergue said “To guarantee the swift deployment of our ACT technology in the French market, it was essential that Ecocem opted for the most relevant national technical assessments. This assessment provides clear evidence of ACT1’s workability, durability, safety and strength, demonstrating it is safe to use across the construction ecosystem.”

Ecocem received a European Technical Evaluation (ETE) for ACT in early 2024. Further iterations of ACT will be subject to similar assessments in France and the EU.

France: Ecocem will invest €170m to build four new production lines for its ACT low-carbon cement technology in Fos-sur-Mer and Dunkirk. This follows a €50m investment at Ecocem’s Dunkirk facility to deliver its first production line. The additional manufacturing capacity will come online between 2028 and 2030. At full capacity, ACT production in France will reach 1.9Mt/yr, reducing CO₂ emissions by 800,000t/yr and creating 60 jobs. The French government has reportedly committed to working closely with Ecocem to identify operational and financial solutions to accelerate and deliver the expansion.

Ireland: Ecocem has secured €4m in research funding as part of the European Innovation Council’s Pathfinder Challenges 2024 in order to optimise electric arc furnace (EAF) slag for low-carbon cement production. The four-year programme is funded by Horizon Europe and will explore ways to enhance EAF slag reactivity and its suitability as a supplementary cementitious material without compromising cement durability. The project was submitted to the Pathfinder Challenge 2 call: “Towards Cement and Concrete as a Carbon Sink.”

Corporate development executive director Eoin Condren said “For many years, we have been pioneering the use of a range of slags and cementitious materials to create scalable and durable low-carbon cement. Thanks to this grant, we will continue our groundbreaking work as the steel industry transitions to new manufacturing processes, delivering a viable solution for a new generation of waste from steel.”

Greece: Ecocem has signed a partnership agreement with Titan Group to co-develop and deliver low-carbon cements using Ecocem’s ACT technology. The collaboration will initially target the Greek market, replacing a portion of clinker with locally sourced supplementary cementitious materials (SCMs) to reduce cement CO₂ emissions by up to 70%.

Group managing director Donal O’Riain said “Signing this co-development and technology transfer agreement with a partner of Titan Group’s size and calibre is a real demonstration of confidence in our ACT technology. This partnership has the potential to accelerate the use of a range of SCMs with ACT technology and deliver rapid and low-cost decarbonisation of the cement industry globally.”

France: Ecocem will build its first production facility dedicated to ACT, its low-carbon cement technology, at its Dunkirk site. The new site will be operational by 2026 with an initial capacity of 300,000t/yr of ACT.

The expansion will increase the plant's total production capacity to beyond 1Mt/yr and strengthen Ecocem’s operations in northern France, Paris and export markets. The first half of 2025 will see the installation of the key component of the facility, the mill, which will produce the required fillers, as well as expansion of blending and storage facilities. ACT is expected to be delivered to the market in the second half of 2026.

The total investment for the expansion is €50m, funded through a ‘green loan’ from the EthiFinance agency and supported by the French government and local authorities. France 2030's ‘Première Usine’ initiative also awarded a €3.6m grant, with additional grants from the Hauts-de-France Region and Dunkirk Urban Community.

Ecocem will partner with limestone supplier CB Green for the commercial production and delivery of ACT at the Dunkirk site.

France: Bouygues Construction and Ecocem have signed a partnership to facilitate the use of Ecocem’s low-carbon ACT cement technology in Bouygues Construction’s projects.

The collaboration involves three stages of testing and validation. First, Bouygues Construction will conduct independent laboratory tests to evaluate ACT’s performance. Next, structural concrete walls will be built at Bouygues Construction’s facilities in Chilly-Mazarin, France starting in early 2025, and monitored to ensure thorough testing. Finally, a full-scale mock-up, including all structural elements, will be constructed to assess the in-situ application of ACT technology.  The testing programme aims to integrate ACT technology into Bouygues Construction projects following successful validation.

Europe: Titan Group and Ecocem will partner for the development of Ecocem's low-carbon cement technology, ACT, in Europe. This partnership will produce a new low-carbon cement by substituting a ‘substantial portion’ of clinker with supplementary cementitious materials, reportedly reducing cement's carbon footprint by up to 70%.

Iraq: Eggersmann Anlagenbau has expanded its refuse-derived fuel (RDF) production facility in Sulaymaniyah, operated by Ecocem Environmental Solution, part of the Faruk Investment Group. The expansion includes a new Eggersmann TEUTON ZS 55 single shaft shredder and four additional lanes for biological drying using the CONVAERO system. This system is integral to the Eggersmann RDF process, which converts municipal solid ‘waste’ into high calorific value RDF used by the regional cement producers Gasin Cement Company and Bazian Cement Company. The facility, which has a capacity of 1100t/day of RDF, will see an increase with the expansion. The Eggersmann FUEL process utilises biowaste in RDF production, improving both the quantity and quality of the fuel through biological drying in the CONVAERO system, relying on the natural warmth of the composting process. This method reduces methane emissions at landfill sites by integrating biomass into the fuel, according to the company.

Business development manager at Eggersmann, Eugen Becker, said "A particularly high quality substitute fuel is being produced with the Eggersmann FUEL process in Sulaymaniyah, whose net calorific value can be precisely tailored to the customer’s needs over the adjusting of the drying period. This quality makes a noticeable economic difference."
