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.”

Global: The Global Cement and Concrete Association (GCCA) and the United Nations Industrial Development Organization (UNIDO) have entered a partnership to accelerate the decarbonisation of the cement and concrete industry, focusing on the global south. This collaboration, formalised through a memorandum of understanding, commits both organisations to advancing sustainability and decarbonisation. Their joint efforts will include developing low-emission technologies, organising international events and promoting industry solutions globally.

GCCA CEO Thomas Guillot said "Through our net zero roadmap and the accelerator programme we have put in place, we are already working with policymakers, governments and industry to overcome procurement and resourcing challenges across the global south. Having this ground-breaking agreement with UNIDO is a natural progression which we hope will fast-track progress in a meaningful way."

Vietnam: Siam Cement Group (SCG) has announced the launch of a new 20% reduced CO₂ cement in Vietnam. Việt Nam News has reported that SCG achieved the reduction through technical upgrades to its cement production, alternative fuels co-processing and waste heat recovery. The producer said the move is a response to growing demand for lower-carbon alternatives in the country’s cement market.

Deputy country director for Vietnam Tanakorn Theeramankong said "For the first time, SCG has introduced a new low carbon cement to the Vietnamese market, marking a significant step forward in our journey to achieve net-zero emissions. By pursuing advanced technologies to develop low carbon cement, we not only reduce our environmental impact but also set a new standard for Vietnam’s construction industry."

Europe: A joint statement by Cefic, Cembureau, Eurofer, Eurometaux and WindEurope has called for accelerated wind deployment as part of a new industrial deal to further support the Green Deal in the European Union (EU).

The organisations say that Europe's energy-intensive industries, like cement and steel, are vital for the wind energy supply chain. However, they assert that current policies lack frameworks that effectively support these industries, which have faced production curtailments due to the energy crisis. Addressing these challenges is fundamental to a new Industrial Deal for Europe, aimed at boosting renewable energy deployment to reduce energy costs. According to the International Energy Agency, the growth in solar photovolatics and wind capacity from 2021 to 2023 helped keep electricity prices lower than they would have been otherwise. Coupling the EU Green Deal with an industrial deal is seen as a strategy to provide regulatory stability, encourage investments in decarbonisation, and enhance competitiveness.

Koen Coppenholle, CEO of Cembureau, said "Cement is a critical component in the construction of wind turbine foundations and their recycling, while the growth of renewable energy is indispensable to achieve the cement sector’s net zero ambition. We look forward to a good cooperation with the wind energy sector to support a strong EU industrial policy and help building the business case for decarbonisation investments," said Coppenholle.

Philippines: OceanaGold Philippines (OGPI) is collaborating with Holcim Philippines to assess the feasibility of using mine tailings in cement production. Holcim will begin by acquiring tailing samples from OGPI for initial testing, aligning with its ‘circular economy’ program that integrates waste materials into cement. Both companies are committed to advancing the study, pending formal partnership arrangements and necessary permits.

OGPI President Joan Adaci-Cattiling said “We’re just waiting for the permit. Right now, we’ve found a way to put plan tailings to good use.”
