UK: Cemvision has launched one of the UK’s first commercial applications of its low-carbon Re-ment cement technology at a STOREX self storage development in Sunbury, near London. The foundational slabs for the site employ Cemvision's Re-ment Massive product, which replaces traditional Portland cement. Recent laboratory tests have shown that the product achieves a 75% CO₂ reduction and a 28-day compressive strength, that reaches the C50/60 classification, compared to traditional Portland cement. STOREX and Cemvision have signed a Letter of Intent for further collaboration in the UK and other markets.

“This project is a landmark achievement for Cemvision as we bring the benefits of green cement to UK customers,” said Oscar Hållén, CEO of Cemvision.

Cemvision says that its Re-Ment Massive technology reaches different levels of CO₂ reduction depending on application and local conditions, with the product already having achieved more than a 95% reduction compared to Portland cement in demo production in the EU, according to the company.

Portugal: CBMI has signed an engineering, procurement and construction contract with SECIL Cement Group for the renovation of the 1800t/day clinker line at the Maceira plant.

The project includes the installation of a new firing system and a series of upgrades to improve energy and heat efficiency. The upgrade encompasses five decarbonisation measures, including a 100% alternative fuel design rate, with the aim to decrease CO₂ emissions by 30% compared to 2019 levels. This would reportedly reduce CO₂ emissions to 550kg/t of clinker.

US: The US Department of Energy's (DOE) Office of Fossil Energy and Carbon Management has selected Cemex's Knoxville cement plant in Tennessee as the site for a carbon capture, removal and conversion test centre. The project is part of a US$101m initiative shared among five projects that aim to decarbonise cement plants and power facilities.

Cemex, in collaboration with the University of Illinois Urbana-Champaign (UIUC) and a coalition of US cement producers, will develop the conceptual design, business, technical and managerial frameworks for the test centre under Phase 1. Phase 2 will involve constructing and operating the centre to evaluate advanced carbon management systems.

Jaime Muguiro, president of Cemex US, said “While we are making steady progress, the cement industry has the opportunity to accelerate the pace of our decarbonisation even more. I am excited that our Knoxville cement plant has been selected as the host site for the carbon capture test centre. Through collaboration and continuous innovation with the University of Illinois and industry peers, Cemex is committed to advancing decarbonisation solutions.”

Europe: Capsol Technologies has been awarded an engineering services agreement for a pre-FEED (front-end engineering design) study on its CapsolEoP carbon capture technology at a cement plant in Europe, aiming to capture 600,000t/yr of CO₂.

Johan Jungholm, chief of business development at Capsol Technologies, said "We are building on our commercial traction within cement, where Capsol has emerged as a preferred carbon capture technology provider. CapsolEoP can operate with up to 50% lower energy use than traditional post-combustion technologies such as amines. This, together with reduced complexity, has the potential of reducing levelised capture costs by 20-60% for cement plant owners looking to decarbonise their operations.”

Austria: RHI Magnesita and MCi Carbon, supported by €3.8m in funding under the Australia-Austria Industrial Decarbonisation Demonstration Partnership Program, are moving forward with plans to establish the world’s first carbon capture and utilisation (CCU) plant in the refractory industry at Hochfilzen, Tyrol.

The funding, provided by the Austrian Climate and Energy Fund and the Australian Department of Climate Change, Energy, Environment and Water, will support the CCUPScale project. This includes raw material analysis, pre-demonstration trials, low-carbon product development, process engineering and industrial integration.

The plant is expected to begin operations at RHI Magnesita’s facility in 2028 and aims to capture, convert and utilise 50,000t/yr of CO₂ to produce ‘CO₂-negative’ mineral products. The initiative uses MCi Carbon's mineral carbonation technology to reduce Scope 1 emissions and transform CO₂ into value-added materials.

Constantin Beelitz, regional president Europe, CIS & Türkiye at RHI Magnesita, said "This funding approval shows that we are on the right track with this project. For industries with unavoidable emissions like ours, CO₂ capture is currently the only viable path to achieve net-zero by 2050. However, we go one step further by not only capturing CO₂, but also converting it into products that provide solutions for us and other hard-to-decarbonise sectors, such as the cement industry."

US: The Department of Energy’s (DOE) Office of Fossil Energy and Carbon Management has announced US$101m in funding for five projects to establish carbon capture, removal, and conversion test centres for cement plants and power facilities. The test centres aim to cost-effectively research and evaluate technologies to capture and convert CO₂ into products from utility and industrial sources, or by removing CO₂ from the atmosphere. The initiative aims to reduce CO₂ emissions, promote sustainable technologies and create job opportunities.

Notable projects include the University of Illinois in Urbana, which plans to design a test centre to evaluate carbon management technologies for the cement industry, and Holcim US, which intends to establish a Cement Carbon Management Innovation Centre at its Hagerstown facility in Maryland.

Brad Crabtree, assistant secretary for Fossil Energy and Carbon Management, said “Carbon management technologies such as carbon capture can significantly reduce emissions from fossil energy use and key industrial processes, like cement production. By investing in test centres, we are helping reduce barriers to commercial-scale deployment of carbon capture, conversion and removal technologies that will ultimately help reduce pollution and create jobs.”

Lithuania: Capsol Technologies has commenced its first CapsolGo demonstration campaign at the Akmenės Cementas plant in Lithuania, owned by Schwenk, to evaluate its carbon capture technology.

Schwenk plans to test Capsol’s technology at two cement plants, with a combined CO₂ capture potential of 1.5Mt/yr. Following the demonstration campaign at the Akmenės plant in Lithuania, the CapsolGo unit will be transferred to Schwenk’s Brocēni cement plant in Latvia, where a feasibility study was conducted in 2024.

US: The US Department of Energy (DOE) has awarded funding for two Leilac projects to conduct preliminary front-end engineering design (pre-FEED) studies, subject to final negotiations.

A project at Roanoke Cement Company in Virginia, led by Titan Group in partnership with Leilac, Amazon and Virginia Tech, received US$1.49m. It aims to capture over 500,000t/yr of CO₂ from cement Scope 1 emissions using Leilac’s technology.

A project at Mississippi Lime Company in St Louis, Missouri, in partnership with Leilac, Industrial Ally and Nuada, received US$1.5m. It seeks to achieve net-zero lime manufacturing by integrating Leilac’s CO₂ capture technology with Nuada’s carbon capture system for combustion emissions.

Calix CEO Phil Hodgson said “We look forward to concluding the grant agreements and developing these exciting projects that have the potential to demonstrate industry-leading solutions to produce both low-carbon cement and lime at commercial scale.”

Greece: Heracles, part of the Holcim Group, has signed a front-end engineering design contract (FEED) with Air Liquide for CO₂ capture, liquefaction, storage and dispatch facilities at the Heracles plant in Milaki, as part of the Olympus carbon capture and storage (CCS) project. The project will enable the plant to capture and store 1Mt/yr of CO₂ and is scheduled for full operation in 2029. The captured CO₂ will be liquefied and transported by sea to the offshore sequestration facility in Prinos in the northern part of the Aegean Sea.

Japan: Fortera is collaborating with Sumitomo Corporation to introduce its ReCarb technology in Asia, starting with Japan. The two companies have signed a memorandum of understanding to deploy Fortera’s bolt-on ‘low-to-zero-carbon’ cement plants across the region, focusing on the largest cement manufacturers.

Fortera’s ReCarb process converts industrial CO₂ directly from cement production into cement that is reportedly third-party verified as having 70% less embodied carbon tonne-for-tonne than ordinary Portland cement. When paired with renewable energy, Fortera can achieve zero-CO₂ cement production.

Ryan Gilliam, CEO of Fortera, said "This partnership is a pivotal moment for the future of sustainable cement production, because you can’t make a meaningful impact on the industry’s carbon emissions without partnering with major industry players in Asia, which is home to the largest cement market in the world."
