US: Holcim has invested in Travertine, utilising the startup's technology to bind CO₂ from direct air capture into advanced mineral components for permanent carbon sequestration. This investment, made through Holcim MAQER Ventures, will scale Travertine’s technology for cement decarbonisation.

Chief Sustainability Officer at Holcim, Nollaig Forrest, said, "We're excited to work with innovative startups like Travertine to advance our goal of making decarbonised cement and concrete a reality at scale this decade. Driving circularity, Travertine reduces carbon emissions by capturing and binding CO₂ into advanced mineral solutions."

Spain: Mondi has launched the 'SolmixBag', a sustainable packaging solution, in collaboration with Cemex in the Balearic Islands of Ibiza, Mallorca and Menorca. The single-layer paper bag is designed to store and transport dry mortar, dissolving in the mixing process and integrating with the cement to reduce waste. The Balearic Islands have strict legal requirements on landfilling, waste incineration and extended producer responsibility, which have reportedly initiated the partnership.

Commercial Director at Mondi, Fabio Barbieri, said "This is an exciting step in the trajectory of SolmixBag, which offers an easy and convenient solution to use on construction sites. The product launch brings our MAP2030 goals to life by effectively reducing waste, and also illustrates our collaborative approach.”

US: Queens Carbon has secured a US$14.5m grant from the US Department of Energy under its SCALEUP program. The funding will support the pilot of Queens Carbon's low temperature, ‘zero CO₂’ emission technology at an existing cement production site. Queens Carbon's supplementary cementitious materials, which replace 20-50% of the high-CO₂ binder in cement, will be produced at a pilot plant with a capacity of 10t/day.

CEO Daniel Kopp said “This SCALEUP grant is a tremendous step forward on our path to commercialisation. Partnering with the Department of Energy and a major cement industry player to deploy, operate, and optimise our 10t/day pilot plant will put us on an accelerated path to gigatonne-scale CO₂ reductions.”

India: Shree Cement says that it has reached 1GW captive power capacity across its plants, after commissioning a new 19.5MW solar power plant at a facility in Andhra Pradesh. Renewables account for 499MW (50%) of the total. Shree Cement says that its investments in renewables to date total US$479m. NBM & CW News has reported that the company has current planned new investments worth US$120m in renewables. This will cover 132MW-worth of solar, 36MW of wind and 34MW of waste heat recovery power capacity.

Switzerland: Holcim has acquired recycling, ready-mix concrete and aggregates company Cand-Landi Group. The company employs 250 people across its operations in Western Switzerland. Holcim plans for Cand-Landi Group to supply alternative raw materials and fuels for use at its Eclépens plant. It says that the acquisition will increase its recycling capacity of construction and demolition materials by 100,000t/yr.

Holcim CEO Miljan Gutovic said "The acquisition of the Cand-Landi Group will advance decarbonisation and circularity in Switzerland, a lighthouse market for innovation at Holcim. I look forward to welcoming all 250 employees of the Cand-Landi Group and investing in our next chapter of growth together."

Switzerland: Neustark has raised US$69m in a growth equity round to scale up its carbon dioxide removal technology. The funding, led by Decarbonisation Partners—a collaboration between BlackRock and Temasek—will support Neustark's aim to permanently remove 1Mt of CO₂ by 2030. Climate tech growth investor Blume Equity also joined the round, alongside existing backers Holcim, Siemens Financial Services, Verve Ventures and ACE Ventures.

Neustark has developed a technology that captures biogenic CO₂ at its source and utilises it in building materials through an accelerated mineralisation process. This method is currently applied at 19 carbon capture and storage plants in Switzerland, Austria, Liechtenstein and Germany, with 40 more under construction across Europe.

Johannes Tiefenthaler, co-CEO and founder at Neustark, said “We turn the world’s largest waste stream, demolition concrete, into a carbon sink. In the past year, we have already deployed our unique solution at 19 sites. This growth investment will take us into the next exciting phase of our mission, helping us to further scale our impact across Europe, enter new markets in North America and Asia Pacific, and develop new solutions to store even more CO₂ in mineral waste streams.”

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.”

Global: Heidelberg Materials has launched the sixth edition of the Quarry Life Award, encouraging global participation to develop sustainable quarry management solutions. Open to researchers, students, communities, non-government organisations (NGO) and nature enthusiasts, the competition offers a prize fund of around €300,000 and aligns with the company's commitment to the Global Goal for Nature. Partnering with organisations like BirdLife International, the initiative aims to enhance biodiversity at extraction sites. Since its inception in 2011, the Quarry Life Award has spurred over 450 projects aimed at biodiversity protection. The 2025 edition will see Heidelberg Materials open its quarries for selected projects, with Türkiye, Egypt, Kazakhstan and Indonesia joining as new participants.

Chief sustainability officer Nicola Kimm said "The Quarry Life Award is a key element of our biodiversity strategy, which relies on strong partnerships with stakeholders to engage across science, industry, and local communities. To truly move from biodiversity loss to gain, a concerted effort is needed by everyone, working together in the recovery of nature at a landscape scale."

Germany: Berlin-based AI startup Alcemy, in partnership with German cement producer Spenner, has produced a commercially viable low-carbon cement alternative named ‘CEM X’. This product reportedly reduces carbon emissions by 65% and has less than 30% clinker content, according to the company. The composition incorporates a blend of 33% granulated blast furnace slag and 37% limestone.

Alcemy CEO Leopold Spenner said "With 'CEM X,' we have reached a significant milestone on our journey to decarbonising the cement industry.”

Germany: Heidelberg Materials, in partnership with Linde, is constructing a large-scale carbon capture and utilisation (CCU) facility at its Lengfurt cement plant, set to start operating in 2025. According to the company, it will be the first of its kind. The project is named Capture-to-Use (CAP2U) and will capture 70,000t/yr of CO₂.

Christian Knell, general manager of Heidelberg Materials Germany, said "With the amine scrubbing technology applied here in Lengfurt, we are demonstrating the capture and utilisation of CO₂ on an industrial scale for the first time in the cement industry in Germany.”
