Netherlands: Sweden-based Paebbl's demonstration plant at its Rotterdam research and development centre has reached a cumulative 500 hours of production in the eight months since it entered operation in March 2025. The plant uses captured CO₂ as a feedstock to produce carbon-storing cementitious materials. Meanwhile, Paebbl has operated its pre-existing pilot plant for a cumulative 2000 hours. The producer is now designing its first commercial-scale plant.

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?

UK: N+P Group announced that investment has been approved for its new 5t/hr research and development pilot line at its Hartlepool site. The installation will separate biogenic fractions from hard-to-process waste, including municipal solid waste and material from materials recovery facilities and other processing sites. The output will be a cleaned, high-biogenic alternative fuel, with biogenic content expected to exceed 70%. N+P aims to deliver the first volumes from its facility in the first quarter of 2026.

Morocco: Ciments du Maroc has reached a milestone in its ALGACEM initiative with the first delivery of CO₂-derived products under the ALGACE brand from its Safi cement plant. The pilot project captures and recovers CO₂ using microalgae, transforming the carbon captured during the cement production process into bioproducts.

The company said the result confirms the technical and economic feasibility of the project and its compatibility with existing industrial infrastructure, laying the groundwork for a reproducible model for the wider cement sector.

France: Cement producer Eqiom has inaugurated a €2.5m pilot station for the continuous injection of alternative fuels at its Rochefort-sur-Nenon plant. The new facility enables the injection of wood fines - treated wood residues sourced from local sawmills - directly into the kiln at a rate of 5000t/yr.

The facility has reduced its coal use from 30,000t/yr to 8000t/yr. Currently, more than 70% of the plant’s kiln fuel comes from alternative sources, with the site now targeting 80%. Since the 1990s, the plant has successively used liquid chemical waste, animal meal and solid recovered fuels (SRF), which together accounted for 50,000t in 2024. Eqiom is also developing new cement types with lower clinker content by incorporating more pozzolans, as part of its broader decarbonisation efforts.

Pierre Bernard, Eqiom’s head of cement manufacturing, noted that national cement production fell from 20Mt/yr in 2022 to 15Mt/yr in 2024, equivalent to 1960 levels, due to a decline in construction activity.

Germany: Rohrdorfer has inaugurated a new pilot plant for tempered clays at its Rohrdorf cement facility in a ceremony attended by regional and state officials. They included Parliamentary State Secretary to the Federal Ministry of the Interior Daniela Ludwig, who cut the ribbon alongside Rohrdorfer managing director Mike Edelmann.

The pilot plant has been operational since July 2025 and activates up to 50t/day of raw clay through thermal treatment. Tempered clays can replace clinker in cement, reportedly helping to cut emissions by around 30%, according to the company. The project is funded by the Federal Ministry for Economic Affairs and Climate Protection and the EU, and will receive up to €8.65m in funding.

Daniela Ludwig said “With this new plant, the Rohrdorf cement plant is once again proving that it is one of the most innovative companies in our region. Decarbonising the cement industry is a key task if Germany is to achieve its climate goals as planned.”

By the end of 2026, Rohrdorfer’s Net Zero Emission team will determine the optimal composition of raw clays and refine the thermal treatment process, paving the way for a large-scale facility capable of achieving up to 60% CO₂ reductions.

Mike Edelmann said “We’ve achieved a lot within our plants, but our influence ends at the factory gates. The lack of planning security regarding CO₂ transport and storage, uncompetitive electricity prices and an uncertain mining landscape are holding us back. We urgently need more support from policymakers if climate targets are to be met.”

South Korea: The Ministry of Environment has announced a pilot project to recycle waste fabric scraps from sewing factories into alternative fuel for the cement industry. The agreement has been signed with: textile companies Pang Rim, Sewang, Sinhan Spinning & Textile; cement companies Ssangyong C&E and Asia Cement; and the Korea Recycling Service Agency (KORA). It expands on an earlier initiative launched in 2024 with four Seoul districts.

Under the project, fabric scraps that were previously incinerated or landfilled will be separated, sorted and processed into intermediate fuel, which cement plants will use in the production process. The Ministry said that KORA will support raw material supply and recycling logistics, while cement firms will adopt the fabric-derived fuel to reduce waste and fossil fuel use.

Kim Go-eung, Director General of the Resources Circulation Bureau, said “The separation, sorting and recycling of waste are essential elements for producing high-quality recycled raw materials. To establish a circular system, we will continue to identify and expand various measures so that the supply of excellent recycled raw materials and the securing of demand sources can be balanced.”

Latvia: Schwenk Cement Latvija has inaugurated a carbon capture test base at the Brocēni cement plant, according to a post on Linkedin by the producer. Throughout 2025, several technologies will be tested at the site to determine the best solution for Brocēni and Schwenk’s other plants. The Broceni carbon capture and storage (CCS) project aims to capture 800,000t/yr of CO₂. The event was attended by Latvian prime minister Evika Silina, German embassy representative Heike Janče and staff members from Schwenk Latvija.

The final investment decision is planned for 2027, with completion in 2030. Schwenk said the project will strengthen exports to Estonia, Finland and Sweden and establish a regional value chain for low-CO₂ cement.

US: Ash Grove Cement, part of CRH, has deployed Boston Dynamics’ autonomous robot ‘Spot’ at its cement plant in Washington in a year-long pilot to boost efficiency and safety. Operating more than 80 hours a week, the four-legged robot conducts routine inspections using a 4K camera and laser scanning, detecting anomalies and alerting teams before failures occur.

The company said that the robot can measure refractory bricks inside cement kilns, reducing risks by keeping employees out of hazardous environments. During the trial, Spot detected a failing bearing in rotating equipment, preventing unplanned downtime. Ash Grove said that the technology improves site safety, frees skilled teams for complex work and enables real-time monitoring in the hot and dusty conditions at the plant.

Plant manager Andy White said “Our aim for Spot is that, at the moment, we don’t have preventative or proactive maintenance routines on night shifts and the weekends. And, also, our labour force has to spend a lot of time recording data rather than analysing it… Spot can do this for us. When we come in the mornings, we already have reported generated, so we can proactively fix those issues thather than spending eight hours trying to find them.”

Norway: thyssenkrupp Polysius will supply the kiln system for SMA Mineral’s quicklime plant, designed to operate without CO₂ emissions using SaltX’s electric calcination technology. The pilot facility is scheduled for completion in 2027, and will produce 40,000t/yr of quicklime. The project has received €24m in funding from Norwegian state enterprise Enova.

thyssenkrupp Polysius CEO Christian Myland said “We are proud to contribute to this landmark project that sets a new standard for sustainable lime production. Our collaboration with SMA Mineral and SaltX Technology demonstrates how industrial partnerships can accelerate the transition to net-zero emissions. This project is a testament to our commitment to engineering solutions that drive decarbonisation.”

The partnership between SaltX Technology and thyssenkrupp Polysius follows the signing of a Letter of Intent in February 2025.
