US: Terra CO2 (Terra) has raised US$124.5m in series B equity funding, with co-leads Breakthrough Energy Ventures, Eagle Materials, GenZero and Just Climate, the round included investment from Barclays Climate Ventures. Additional strategic investors to join the round include Cemex and Siemens subsidiary Siemens Financial Services.

The capital will support the construction of Terra’s first 240,000t/yr advanced-processing facility in Dallas Fort Worth, expansion of its team and sites, and development of further commercial-scale cementitious projects.

CEO Bill Yearsley said “Terra's mandate is to deliver cementitious material solutions that the market would purchase solely based on cost and performance, even if there was no carbon benefit. The fact that Terra's cementitious materials also offer significant carbon mitigation is an additional advantage for the built environment.”

Terra produces supplementary cementitious materials as an alternative to traditional Portland cement, from resources like fly ash. Its second product, Opus Zero, is currently in the testing phase and would serve as a complete replacement for Portland cement.

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.”

US: Ozinga has broken ground on a 1Mt/yr alternative cement grinding plant in East Chicago, Indiana. The plant is equipped with a Gebr. Pfeiffer MVR5300-C6 vertical roller mill. It will produce ASTM C989-compliant slag cement and other blended cements. When operational in 2026, it will be the largest of its kind in North America, and avoid 700,000t/yr of CO₂ emissions from conventional cement production. Its location offers strategic rail, road and shipping access to large markets in the US and Canada.

East Chicago Mayor Anthony Copeland welcomed an anticipated 150 new jobs resulting from construction and subsequent operations at the plant.

US: Researchers at the Massachusetts Institute of Technology (MIT) have developed an AI tool to compare studies of alternative raw materials for cement production. A collaborative team from the MIT Concrete Sustainability Hub and MIT’s recycling research programme, Olivetti Group, published its findings in the Nature journal. The team mined 5.7m academic publications to identify 14,434 alternative raw materials. These belonged to 19 ‘types,’ including bottom ashes, fly ashes, calcined clays and slags, as well as less homogenous types such as biomass ashes, glasses and mine tailings. The study more than doubles the number of fly ashes and slags recorded on a database of this kind. The tool then provides a unified assessment of cementitious reactivity and pozzolanicity, also accounting for variables in particle size and amorphous content.

Canada/Greece: Titan Group and Carbon Upcycling Technologies have entered into a memorandum of agreement to explore the commercial deployment of Carbon Upcycling’s technology for producing local, low-carbon building materials. Carbon Upcycling will conduct feasibility studies at two Titan cement plants, with the aim of producing supplementary cementitious materials using captured CO₂ and local materials.

Carbon Upcycling’s demonstration plant is currently operating in western Canada, and the company is now developing its flagship commercial-scale project in eastern Canada.

Philippines: The Department of Trade and Industry (DTI) has announced that Taiheiyo Cement’s US$67m Luzon Distribution Terminal, which will supply up to 0.7Mt/yr of cement to Luzon, will begin operations in early 2026. The plant will use a high proportion of supplementary cementitious materials (SCM), including fly ash, slags and natural pozzolans.

Taiheiyo Cement has said that the terminal represents the Japan-based company’s long-term commitment to the Philippine cement market and that it is aware of recent DTI rules that aim to safeguard domestic cement producers.

UK: Medcem, a subsidiary of Turkish conglomerate Eren Holding, and UK-based Peel Ports Group will begin construction of a new deep-water cement terminal at the former P&O site at Gladstone Dock, Liverpool. Construction is scheduled to start at the end of May 2025, according to Construction Management magazine.

The €41m project’s first phase will include four silos with a combined capacity of 45,000t for cement and supplementary cementitious materials. The 2.3-hectare site allows for future expansion and increased capacity in subsequent phases. Completion is expected by mid-2026.

Medcem business development and investments director Enver Celikbas said “This new terminal significantly strengthens our presence in the UK market, consolidating our position as the leading provider of low-carbon cement and cementitious materials in Europe. The logistical advantages of Liverpool allow us to enhance our ability to accommodate large vessels and product handling.”

Ghana: CBI Ghana and joint venture partner Heidelberg Materials have commissioned the ‘world’s largest’ calcined clay plant in Ghana, according to an announcement by the German producer. The plant has a capacity of 400,000t/yr of calcined clay and uses local raw materials to reduce reliance on imported clinker.

Hakan Gurdal, member of the managing board of Heidelberg Materials, said “Based on calcined clay technology, we can now extend our offering of innovative, high-quality cement products, while reducing CO₂ emissions and utilising the rich local resources. The project has created over 300 local jobs."

France: Hoffmann Green Cement Technologies has formed a strategic partnership with paper mill Norske Skog Golbey to integrate ash from paper residue incineration into its clinker-free cement. The partners have been collaborating since January 2024 and the first shipment of paper ash for large-scale use was sent in May 2025, after successful testing.

US: France-based Fives Group has launched new subsidiary Fives FCB USA in Alabama to supply the North American market with low clinker blended cement and supplementary cementitious material production equipment and services. Products being promoted include the FCB Horomill, the FCB TSV Classifier and the FCB Rhodax. The unit will share premises with Fives’ North American Construction Services company.

Deputy general manager Alain Cordonnier said “The opening of our subsidiary in the US marks a significant milestone for Fives FCB. We are excited to bring our innovative technologies and expertise to the US market, and we look forward to building strong partnerships with local industry leaders.”
