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."

France: Bouygues Construction and Ecocem have signed a partnership to facilitate the use of Ecocem’s low-carbon ACT cement technology in Bouygues Construction’s projects.

The collaboration involves three stages of testing and validation. First, Bouygues Construction will conduct independent laboratory tests to evaluate ACT’s performance. Next, structural concrete walls will be built at Bouygues Construction’s facilities in Chilly-Mazarin, France starting in early 2025, and monitored to ensure thorough testing. Finally, a full-scale mock-up, including all structural elements, will be constructed to assess the in-situ application of ACT technology.  The testing programme aims to integrate ACT technology into Bouygues Construction projects following successful validation.

Spain: Votorantim Cimentos Spain will invest €3.2m in a new clinker cooler at its Málaga plant, according to Alimarket. The upgrade will reportedly reduce thermal and electrical energy consumption and avoid approximately 11,000t/yr of CO₂ emissions. The project will receive a €725,960 subsidy from the regional government of Andalusia.

US: Oakland, California-based cleantech startup Brimstone has received a US Department of Energy grant worth up to US$189m to establish a plant with a capacity of 80,000t/yr of ‘green’ cement and 20,000t/yr of smelter-grade alumina, according to the San Francisco Business Times. The grant will be paid out in instalments and requires matching funds from new investments, loans and other sources.

The US$378m facility, which is still in the site selection phase, will be located near an existing quarry in order to mine calcium silicate rocks.

CEO Cody Finke said “We’re exclusively looking at brownfield sites. The goal is to build our own plant while utilising existing quarries to ensure a sustainable and economically viable operation.”

Brimstone plans to begin pilot operations in 2025 and aims to have the plant fully operational by the end of the decade. The company is currently testing its decarbonised cement with potential customers from its Oakland research and development facility.
