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.

Sweden: Cemvision has appointed Michael Niska as its chief financial officer (CFO).

Niska holds over 15 years of experience of senior financial roles in the transport and climate technology sectors. He worked as the Head of Business Control at heat pump manufacturer Aria from 2023 to mid-2025. Notable roles before this include the Group CFO of transport company LOTS Group from 2019 to early 2023. He also worked for Scania from 2010 to 2017. Niska holds a master’s degree in Industrial Engineering and Management from Linköping University.

Sweden: Cemvision has developed a patent-pending beneficiation process to upcycle electric arc furnace (EAF) and basic oxygen furnace (BOF) slags into high-performance supplementary cementitious material (SCM), while recovering valuable metals.

Third-party testing found the material performs as well as or better than ground granulated blast-furnace slag (GGBS). Cemvision recovers 99% of the iron oxide content from EAF slag for reuse in steelmaking, as well as other metals like chromium.

The output will support Cemvision’s Re-Ment Massive and Rapid products as clinker-replacing SCMs. The process was piloted with metallurgical research institute Swerim.

Cemvision CEO Oscar Hållén said “This is a game-changer not only for the cement industry but for steel producers as well. Our process enables high-performing cement products from materials that would otherwise be treated as waste. With this innovation, we're proving that decarbonisation and circularity can go hand in hand, and at scale.”

Sweden: Cemvision and S:t Eriks have entered into a partnership agreement as a result of several pilot projects using Cemvision’s cement in S:t Eriks’ production. The partners have signed a letter of intent to develop and implement sustainable concrete solutions within water and sewage infrastructure. Having already tested Cemvision’s cement in its own production, S:t Eriks will then implement the cement in commercial projects. The product reportedly offers high resistance to sulphate and acid attacks, which contribute to longer service life.

In the coming months, Cemvision and S:t Eriks will continue testing to explore the potential for broader implementation of the cement in water and sewage systems.

Sweden: Skanska and Cemvision will enter into a partnership, which will combine Skanska’s experience in low-carbon construction solutions and Cemvision’s circular cement technologies. The collaboration will begin in spring 2025 and will see Skanska scale up a new generation of cement with up to 95% lower climate impact compared to traditional Portland cement.

The signed letter of intent marks the first step towards a future off-take agreement, in which Skanska will secure access to Cemvision’s cement for implementation across its projects. The company is planning its first pilot projects for the near future.

Sweden: Swedish cement manufacturer Cemvision has entered a strategic partnership with Norway-based residential developer JM to develop ‘climate-friendly’ cement and concrete. As part of the agreement, JM has also acquired a minority stake in Cemvision.

Cemvision’s cement reportedly reduces CO₂ emissions by up to 95% compared to traditional cement, through the use of recycled industrial waste from mining and steel industries, combined with renewable energy in its kiln operations.

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.

Global: Vattenfall and Cemvision have agreed to develop and supply low carbon cement, aiming to cut CO₂ emissions by 95% from traditional levels, according to Vattenfall. This agreement is underpinned by a letter of intent. The partnership utilises Cemvision’s technology, producing cement from recycled industrial materials and powered by renewable energy.

Cemvision CEO Oscar Hållén said "We are delighted to deepen our partnership with Vattenfall and to welcome them to our growing customer base. Already today in our demo production, we are reducing carbon emissions by 80%, and as we optimise processes and supply chain, we will reduce by up to 95% by 2030. Near-zero emission cement is the most efficient way to achieve significant climate benefits without increasing the overall cost of a construction project.”

Sweden: Peab has entered a product delivery agreement with Stockholm-based start-up CemVision, starting from 14 May 2024. CemVision has developed a cement that reportedly reduces CO₂ emissions by over 95% compared to traditional cement, by replacing limestone and fossil fuels with refined industrial waste and renewable energy. Over the next few years, Peab will use CemVision's ultra-low carbon cement for various projects, including infrastructure, water treatment, foundation work and prefabricated concrete.

Oscar Hållén, CEO of CemVision, said “We are thrilled to be able to deliver our product to Peab. We see that green cement has become crucial for entire industries to be able to meet their climate commitments. The demand is already enormous and all forecasts indicate that it will only increase.”
