Europe: Vattenfall has signed a commercial agreement with Cemvision to supply near-zero-CO₂ cement for its onshore wind infrastructure projects across Europe from 2028. Cemvision’s Re-ment Massive product will be prioritised by subcontractors and has the potential to cut emissions by up to 95%, according to the company. Deliveries will come from Cemvision’s first industrial-scale plant and follow a 2024 letter of intent signed by the two companies.

Cemvision CEO Oscar Hallen said “This long-term agreement for the supply of our near-zero cement is a foundational step in transforming the cement market, and we are proud to take the partnership with Vattenfall to the next level. Our cement is one of the most cost-efficient ways to decarbonise construction. Moving from pilot to commercial action is how the transition becomes real.”

Vattenfall aims for 10% of its cement and concrete purchases to be near-zero by 2030, with the deal making it possible to reach 20% by 2028 and supporting a 50% supply chain emissions reduction by 2030.

Sweden/India: Cemvision has received a grant from the Swedish Energy Agency to conduct a joint feasibility study with Tata Steel to convert basic oxygen furnace (BOF) and electric arc furnace (EAF) slags into feedstock for near-zero-CO₂ cement. The 10-12-month study will assess the technical and economic viability of a scalable slag valorisation model, ahead of a planned demonstration facility at Tata Steel’s site.

Cemvision CEO Oscar Hållén said “Being able to, at scale, turn environmental liabilities into valuable resources is exactly the kind of climate innovation heavy industry needs. In partnership with Tata Steel, we hope to show how steel slag can become a cornerstone in near-zero CO₂ cement, while metals are recovered and returned to steel production.”

The project is part of the India-Sweden Industry Transition Partnership (ITP), announced during Cop30 in Belém, Brazil. Tata Steel also received a grant from India’s Department of Science and Technology, with additional partners including IIT ISM Dhanbad and JK Cement.

The Indonesian Cement Association (ASI) has warned that cuts to the Nusantara Capital City project had reduced cement sales so far in 2025. Yet also this week the ASEAN Federation of Cement Manufacturers (AFCM) launched its 2035 AFCM Decarbonisation Roadmap. Here is a round-up of recent news from the cement sector in Indonesia.

ASI data shows that local cement sales volumes fell by 2.5% year-on-year to 51.9Mt in the first 10 months of 2025 from 53.2Mt in the same period in 2024. Cement production decreased by 5.6% to 52.9Mt. Lower demand was reported in Kalimantan and Java. However, it rose in Sumatra and Nusa, in part, due to road construction. Sadly, Sumatra has been badly affected by floods this week. National cement exports grew by over 20% to 1.1Mt. The ASI is currently hopeful that a government-backed home renovation programme might stimulate demand.

The general picture can be seen above in Graph 1. The local cement sector has generally had a capacity utilisation issue since the mid-2010s. Domestic sales started to catch up but the Covid-19 pandemic disrupted the market. Meanwhile, exports of cement and clinker have been steadily rising since 2014. These are dominated by clinker exports, with the single largest destination being Bangladesh. Other major targets include Taiwan and Australia. The country’s relatively low consumption of cement per capita suggests that the utilisation rate will grow over time.

The local production market is dominated by state-owned Semen Indonesia (SIG) (with a 48.5% share), followed by Indocement (29.1%), Conch Cement Indonesia (7.1%) and Cemindo Gemilang (6.6%). SIG’s sales volumes in the first nine months of 2025 roughly follow the general trend reported by the ASI with local sales down by 1.8% year-on-year to 27.5Mt and exports up by 25.3% to 5.1Mt. The group’s sales revenue and earnings before interest, taxation, depreciation and amortisation (EBITDA) dropped by 3.8% to US$1.52bn and 23.8% to US$198m respectively. Indocement’s revenue fell by a similar rate. Both companies anticipate a modest recovery in 2026.

Something to note from SIG’s financial results and related discussions in 2025 (and earlier) has been its approach to marketing and selling its cement brands in a highly competitive environment. It says it changes its brand mix in different regional locations with varying combinations of market leaders with premium pricing and so-called ‘fighting brands’ with competitive pricing. Yet, eco-brands received a mention in addition to the other two groups in the third quarter report analysts’ discussions suggesting an appetite for potentially lower-clinker cements in a developing market such as Indonesia.

This leads to the second Indonesia-related news story of the week: the 2035 AFCM Decarbonisation Roadmap. The plan intends to reduce net CO₂ emissions from the cement sector in the region by 16% to 190Mt/yr from 228Mt/yr in 2020. 58% of this reduction will be achieved through the use of alternative fuels, 33% via the use of low-carbon cements and 9% through the use of renewable energy sources. Work towards carbon capture, utilisation and/or storage (CCUS) is starting with the aim of supporting capture pilots in the region and planning towards CO₂ transport and storage networks. Similarly, the roadmap urges producers to identify and prepare to use new secondary cementitious materials such as calcined clay and construction and demolition waste.

The race between capacity building and market share has been a familiar one in coverage of the cement market in Indonesia in recent decades. Provided the main companies can endure the competition, it looks set to continue, while demographic trends indicate the need for continued investment. Otherwise more market consolidation is to be expected when the utilisation rate dips too low. What is new though are the higher levels of blended cements and the changes this brings to the market. This can be seen above in the marketing strategy of SIG and the regional decarbonisation strategy. Similar trends are happening everywhere but the effects on a highly competitive market could be pronounced. Particularly if those government-backed schemes that the sector anticipates promote it.

The Global CemFuels Asia Conference will take place on 2 - 3 February 2026 in Bangkok

Austria: Alpacem Cement Austria will invest in new infrastructure at its Wietersdorf site in Carinthia to process and utilise low-CO₂ alternative raw materials in cement production. The project aims to cut process-related CO₂ emissions by 51,000t/yr. The company will construct a new plant, expand conveying and storage facilities and modernise dosing systems to raise the share of alternative raw materials to 35%. The project is supported by a €21.6m grant under Austria’s ‘Transformation of Industry’ programme.

Southeast Asia: The ASEAN Federation of Cement Manufacturers (AFCM) has launched the 2035 AFCM Decarbonisation Roadmap, which it says is the world’s first regional decarbonisation strategy for the cement sector. The roadmap was announced during the 46th AFCM Council Meeting in Brunei Darussalam, chaired by Dr Chana Poomee and attended by cement association leaders from all eight AFCM member countries.

The roadmap sets a shared framework for systematic CO₂ reduction aligned with national climate policies and global environmental goals. Supported by the Global Cement and Concrete Association (GCCA), it is built upon four pillars: expansion of low carbon cement, transition to renewable energy across production processes and enhancing efficiency to reduce energy consumption, deployment of decarbonisation technologies such as carbon capture, utilisation and storage (CCUS), and development of new supplementary cementitious materials.

Member associations from Brunei Darussalam, Cambodia, Indonesia, Malaysia, the Philippines, Singapore, Thailand and Vietnam said that national implementation will vary depending on local energy mix, policies, industrial maturity and material availability. The strategy could reportedly cut regional CO₂ emissions by up to 38Mt by 2035.

US: Heidelberg Materials has announced that it will acquire Walan Specialty Construction Products in Delaware under a binding purchase agreement. The transaction includes a 150,000t/yr capacity slag grinding plant with a vertical mill built in 2022 near the Port of Wilmington. The producer says that this acquisition will further strengthen its low-carbon cementitious portfolio and extend its market reach in the Northeast Region.

India: The Global Cement and Concrete Association (GCCA) India said that the cement industry has installed 1.8GW of renewable energy capacity and aims to add 5GW more by 2030, according to Platts. Around 3% of electricity used comes from renewables and 11% from waste heat recovery. GCCA India said that the average alternative fuel thermal substitution rate (TSR) in the sector is approximately 6%, although some plants have successfully achieved TSRs of more than 20%. It also said that there are developments in the installations of hybrid energy systems, which provide 24/7 electricity for the sector.

Blended cement accounts for 73% of production, and India has reportedly begun producing limestone calcined clay cement. Research is also underway into other low-clinker alternatives. According to a March 2025 report by GCCA India and The Energy and Resources Institute, the industry aims to achieve net-zero emissions by 2070. CRISIL forecasts that the sector will add 160-170Mt/yr of grinding capacity between the financial years 2026-2028, which run from April to March, driven by a healthy demand outlook and high capacity utilisation.

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?

Germany: Dyckerhoff has received general building authority approval for the use of CEM VI (S-LL) cement produced at its Lengerich plant. The German Institute for Building Technology granted the approval for the plant in October 2025 for almost all exposure classes. It combines clinker, granulated blast furnace slag and limestone to produce cement with a lower CO₂ footprint, low heat of hydration and low effective alkali content.

Egypt: Cementir Group has launched two reduced-CO₂ white cement products produced at its Egyptian subsidiary Sinai White Cement across the Middle East and Africa. The D-Carb® range comprises a limestone Portland cement (matching CEM II/A-LL 52.5N requirements according to EN197-1) with around 10% less clinker than the company’s well-known Aalborg White® CEM I 52.5R product, and a CEM II/B-LL 42.5N product that has 20% less clinker than Aalborg White.

“In 2024 and early 2025, we progressively introduced D-Carb products across Europe and the Asia Pacific region, including Australia, where we have received positive feedback from diverse industry segments,” said Michele Di Marino, Chief Sales, Marketing and Commercial Development Officer of Cementir Group. “Today, extending this portfolio to the Middle East and Africa with two tailored variants represents an important milestone in Cementir’s journey toward net-zero emissions by 2050.”
