US: Ecocem has obtained ASTM C1157 certification for its ACT low-CO₂ cement technology, confirming it meets or exceeds strength and durability benchmarks while reducing emissions and energy use. Unlike traditional cement specifications, the standard is performance-based, allowing for innovative formulations.

Founder and group managing director Donal O’Riain said “This is a significant moment for Ecocem and for low-carbon cement globally. Over the past 10 years our solutions have seen significant traction across Europe. The US is one of the largest cement markets in the world, and this certification will support integration into existing supply chains and offers a pathway for the sector to rapidly decarbonise through improved efficiency and without increasing costs or complexity.”

Ecocem is advancing its first North American project, a proposed terminal and milling operation at the Port of Los Angeles, aimed at establishing a reliable low-CO₂ cement supply chain in California. The company says that its low-carbon cement technology, ACT, cuts clinker content by up to 70% by using limestone and locally-sourced supplementary cementitious materials. The announcement follows recent regulatory approvals in France, new investment in production lines in Dunkirk, and partnerships with Bouygues, Vinci and Titan Group.

Algeria: The Minister of Industry Sifi Ghrieb has announced a project to build two new low-carbon cement plants in Djelfa and Relizane in central Algeria with a capacity of 1.5Mt/yr and 2Mt/yr respectively, according to Zawya news. An existing cement plant in Djelfa will also see its capacity expanded by 1.5Mt/yr.

The new projects will boost Algeria’s cement capacity to 42Mt/yr. It currently has a cement demand of 30Mt/yr and exports a surplus of 12Mt/yr of cement. Ghrief reportedly discussed plans to expand the Djelfa plant in March 2025 with a delegation from the China State Construction Engineering Corporation. A separate 2Mt/yr low-carbon cement plant, a partnership between local, UAE-based and India-based companies, is also under construction in El Milia, utilising slag and fly ash from a nearby power station and steel complex.

UK: Material Evolution has partnered with CRH subsidiary Tarmac to launch a pilot project to test applications of its heat-free, 85% reduced-CO₂ cement, MevoCem. The partners aim to demonstrate the suitability of MevoCem cement for use in concrete production in line with the prospective BSI Flex 350 performance-based standard.

Material Evolution’s CEO Liz Gilligan welcomed Tarmac as an ‘early adopter’ of MevoCem cement. In a post to LinkedIn, she said “We have been quietly building something game-changing with CRH and their team at Tarmac. It is bold, it is industrial scale and it is all about cutting carbon where it counts. We are only just getting started.”

Material Evolution currently operates a 120,000t/yr Mevocem plant in Wrexham, Wales.

Mexico: Holcim has placed Mexico at the centre of its NextGen Growth 2030 strategy to ‘drive profitable expansion’ in Europe, Australia, North Africa and Latin America following the spin-off of its North American business. Mexico now plays a strategic role in scaling sustainable construction solutions across the region and will allow Holcim to respond to key global trends such as urbanisation, housing shortages, resilient infrastructure and environmental sustainability.

Holcim Mexico CEO Christian Dedeu said “Mexico is now a strategic market where we will scale innovative solutions for circular and low-carbon construction. Our goal is to triple the recycling of demolition materials, double the Disensa store network and expand our sustainable offering through ECOPact and ECOPlanet.”

Dedeu added “In a region facing major social and environmental challenges, Mexico and Latin America have the potential to lead a new era of sustainable construction. At Holcim, we are committed to scaling solutions that address the climate emergency while building progress for people and the planet.”

US: Hoffmann Green Cement Technologies has obtained ASTM C1157 certification for its H-UKR 0% clinker cement after several months of testing and trials at the University of Miami.

The benchmark standard evaluates cements on their performance, regardless of their composition. H-UKR cement is now officially recognised as a hydraulic cement that can be used in all general construction applications, whether structural or non-structural. Hoffmann Green said that this is the first time that a 0% clinker cement has obtained this certification.

Co-founders Julien Blanchard and David Hoffmann said “This international technical recognition marks a decisive step forward in our certification process, which is part of a broader ambition to expand the applications of our 0% clinker cement through continuous innovation. It validates the reliability and sustainability of our technology on a global scale, in accordance with the most demanding standards. With this certification, H-UKR has confirmed itself as a game changer technology capable of profoundly transforming an industry that has remained unchanged for more than two centuries.”

Australia: Green360 Technologies has launched a 457t bulk calcining run of high-purity kaolin from its Pittong operation in Victoria to produce high-reactivity metakaolin as a substitute for Portland cement.

The calcined product, made from raw ore and reclaimed tailings, will be despatched for testing by industry and government partners. Assessments will focus on compressive strength, durability and resistance to environmental stressors.

Executive chair Aaron Banks said “We have rapidly moved from laboratory-scale testing to now producing commercial quantities of our innovative, high-quality metakaolin product.”

He added “Our low-carbon cement formulations and high-quality, advanced metakaolin can help potential customers, from government to private industry, reduce their usage of Portland cement without compromising on performance or cost.”

UK: Titan Group will build and operate a processing and beneficiating facility for ponded fly ash at the former Fiddler’s Ferry power station in Warrington, following a long-term agreement with site owner Peel NRE. The plant will process 300,000t/yr of wet fly ash from 2027, with scope to double the capacity at a later date. Titan will use the material in low-carbon cement, while Peel NRE will receive help to advance restoration of the site. The ash will reportedly meet BS EN 450 quality standards.

Peel NRE director Kieran Tames said “We are very pleased to have reached this agreement with Titan, which follows years of hard work fully evaluating the potential to transform the waste ash material from the power station directly into a low-carbon construction product. This agreement has the potential to accelerate the recovery of waste ash from the lagoons, enabling their restoration and enhancement as envisaged by the development framework that was approved by the local authority last year. Through our partnership, existing customers will continue to source ash from the site, ensuring continuity of supply for their applications.”
