Malaysia: YTL Cement has received environmental product declarations (EPDs) covering products across its cement, concrete and precast ranges. An EPD is a third-party-verified document that discloses a product’s environmental impact throughout its full life cycle in line with international standards. The newly certified products include the Castle Cement brand, as well as ECOConcrete Grade 40 and Grade 35.

Cementir Group launched two of its lower carbon cement products in the Middle East and Africa markets this week. We’ll take a look at this in more detail and cover other recent products news from cement producers.

Egypt-based Sinai White Cement will manufacture the products under Cementir’s D-Carb umbrella. One will be a Limestone Portland cement, to the CEM II/A-LL 52.5N specification EN197-1, with around a 10% clinker reduction. The other will be CEM II/B-LL 42.5N with around a 20% clinker reduction. Both of these reductions are in comparison to Aalborg White CEM I 52.5R. D-Carb is the name of Cementir’s product range for white low-carbon cements. It was launched in European markets in 2024, with II/ALL 52.5R cement, and then expanded to Asia Pacific regions, including Australia, in early 2025. Cementir says that its customers can switch to D-Carb from CEM I as it “integrates well with their production processes without requiring major formulation changes.”

In late October 2025 Dyckerhoff revealed that it was the first cement manufacturer in Germany to receive general building authority approval (abZ) for the use of CEM VI (SLL) cement in accordance with DIN EN 197-5. The German Institute for Building Technology (DIBt) granted approval for Dyckerhoff’s Lengerich cement plant. CEM VI is a newer type of composite cement similar to CEM II but with a lower clinker content. The SLL type that Dyckerhoff wants to make has a clinker content of 35 – 49 %, granulated blast furnace slag of 31 – 59% and limestone of 6 – 20%. The company says that this cement can be used in more than 60% of all concrete types produced in ready-mixed concrete plants. Its composition is also useful for low-carbon concretes when no fillers, such as fly ash, are available. Dyckerhoff added that the low hydration heat of the cement has a particularly positive effect in massive cast components.

Earlier in October 2025 Rohrdorfer held an inauguration ceremony for a new pilot unit for calcined (they say tempered) clays at its Rohrdorf cement plant. The pilot project started in July 2025 and has been processing up to 50t/day of raw clay. When Rohrdorfer launched the project in early 2024 it said that it was going to use waste heat from the main production line and was also considering the use of hydrogen to provide the remaining amount of heat required. Waste gases produced during calcination were also going to be fed back into the existing waste gas cleaning system of the clinker production line after leaving the pilot plant to further reduce emissions. Rohrdorfer said that its approach was going to be the first time waste heat recovery was going to be used in conjunction with calcining clay.

Meanwhile, in West Africa, Dangote Cement inaugurated its new 3Mt/yr cement plant near Abidjan in the Ivory Coast in mid-October 2024. Around the same time the company launched various products in the country, including its CEM I and CEM II brands 32.5R, 3X42.5N, 3X42.5R and 52.5N. This is a more traditional range of cement products compared to the ones above but note the highlighting of strength. This has been a key selling point for products in this part of the world previously, hence its focus. CEM II is a blended cement that uses lower levels of clinker. One clinker substitute in CEM II products is calcined clay. Gebr. Pfeiffer, for example, said in August 2025 that it was to supply a vertical roller mill to Ciments de Côte d'Ivoire (CIMCI) for clay grinding at its cement plant. There are also a number of other calcined clay projects in the Ivory Coast and other countries in West Africa. Further afield, JK Cement in India also started to market its LC3 clay calcined cement product line in October 2025.

Finally, US-based Amrize launched its ‘Made in America’ label for its cement range this week, “offering builders the guarantee of American manufacturing and quality, supporting American jobs and local communities.” Readers may recall that Amrize was recently owned by Switzerland-based Holcim. However, the company is currently keen to point out that its cement products are “made in the US from its raw materials and processing to manufacturing, meeting rigorous US performance standards.” Amrize does sell blended cements including FortiCem Portland-Pozzolan Blended Cement, ECOPlanet Cements and OneCem Portland Limestone Cement.

Most of the news stories highlighted above demonstrate a trend for blended cements with lower clinker factors. There’s no real change here. This has been happening for a long time and it is being driven by both profit and sustainability motives, although the current bunch of stories may also be turning up to coincide with the COP30 conference in Brazil. Note the inclusion of places outside of Europe and the drive for new blends. Another factor to consider here is protectionism in certain markets, as Amrize’s marketing drive suggests. New blends will also require new certifications, standards and approvals as is the case with Dyckerhoff’s work on CEM VI (SLL). The next trend to watch for will be the market reaction to carbon captured cements, such as Heidelberg Materials’ evoZero product. Will end users pay a premium for zero-carbon cements?

Sri Lanka: Siam City Cement subsidiary INSEE Cement has secured EcoLabel certification for its products, in recognition of their environmental performance. Key initiatives included energy efficiency upgrades, raw materials optimisation, increased alternative fuels substitution, clinker factor reduction and emissions monitoring and control. Daily FT News has reported that EcoLabel Sri Lanka and the National Cleaner Production Centre awarded the label, the first of its kind for any cement producer in Sri Lanka.

Asia: Three national sustainability certification providers have signed a tripartite mutual recognition agreement for harmonised green label criteria for cement products. Ecolabel Sri Lanka, the Singapore Green Labelling Scheme and Thai Green Label agreed to the mutual recognition of each other’s certification of cement. Through the collaboration, the bodies aim to enhance market access to environmentally preferable products across South and South East Asia, Daily FT News has reported.

Europe: Germany-based Heidelberg Materials has begun deliveries of EvoZero carbon-captured cement to customers across Europe. Subsidiary Heidelberg Materials Northern Europe produces EvoZero cement at its net-zero Brevik cement plant in Norway. Early adopters to purchase the product include Sweden-based Skanska for its construction of the Skøyen metro station in Oslo, Norway.

Heidelberg Materials launched a 400,000t/yr, 50% carbon capture and storage (CCS) plant at the Brevik plant on 18 June 2025. The plant’s capture and storage data are verified by certification organisation DNV Business Assurance Germany and digitally recorded in Heidelberg Materials' proprietary Carbon Bank.

CEO Dr Dominik von Achten said "I am proud and pleased that the entire process chain is now in place and that our CCS plant in Brevik is now directly contributing to the reduction of CO₂ emissions in construction. EvoZero is proof of our commitment to driving real measurable decarbonisation and leading the transformation of the construction industry."

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.

US: Hoffmann Green Cement Technologies has obtained ASTM C1157 certification for its H-UKR 0% clinker cement after several months of testing and trials at the University of Miami.

The benchmark standard evaluates cements on their performance, regardless of their composition. H-UKR cement is now officially recognised as a hydraulic cement that can be used in all general construction applications, whether structural or non-structural. Hoffmann Green said that this is the first time that a 0% clinker cement has obtained this certification.

Co-founders Julien Blanchard and David Hoffmann said “This international technical recognition marks a decisive step forward in our certification process, which is part of a broader ambition to expand the applications of our 0% clinker cement through continuous innovation. It validates the reliability and sustainability of our technology on a global scale, in accordance with the most demanding standards. With this certification, H-UKR has confirmed itself as a game changer technology capable of profoundly transforming an industry that has remained unchanged for more than two centuries.”

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.

US: Fortera has achieved ISO 9001:2015 certification for its ReCarb Plant in Redding, California, which produces 15,000t/yr of ReAct low-carbon cement. The international certification establishes protocols for quality management systems and ensures delivery of products and services that meet regulatory requirements. Fortera said that the certification process involved months of internal audits, documentation of operating procedures and responding to third party feedback.

Bahrain: New rules have placed strict demands on local producers and importers. A regulation signed by Industry and Commerce Minister Abdulla bin Adel Fakhro requires all cement sold in Bahrain to meet BS EN 197-1 and GSO ASTM C150 standards and be circulated with a conformity certificate from the Bahrain Standards and Metrology Directorate. News of Bahrain has reported that there will be regular laboratory testing, specific storage and transport conditions, and penalties for non-compliance. The move reportedly marks a push to raise the standard of construction materials.
