Canada: Progressive Planet has secured up to US$3.2m in funding from Sustainable Development Technology Canada (SDTC) to support the construction of a pilot plant for PozGlass, its low-carbon supplementary cementitious material (SCM) made from post-consumer glass. The funding will be distributed over four years, with the first tranche of US$1m received on 31 January 2025.

"PozGlass is our solution to reducing the carbon footprint of cement production. This funding allows us to innovate, reduce emissions and create value from post-consumer glass, a material that has been historically misallocated and considered waste," said Progressive Planet CEO Steve Harpur.

Progressive Planet signed a purchase agreement with Lafarge Canada in June 2023 for all PozGlass produced at the pilot plant, up to a maximum of 3500t/yr. Under the agreement, Lafarge Canada will provide technical guidance and support for the plant’s design, construction and operation.

Sweden: Swedish cement manufacturer Cemvision has entered a strategic partnership with Norway-based residential developer JM to develop ‘climate-friendly’ cement and concrete. As part of the agreement, JM has also acquired a minority stake in Cemvision.

Cemvision’s cement reportedly reduces CO₂ emissions by up to 95% compared to traditional cement, through the use of recycled industrial waste from mining and steel industries, combined with renewable energy in its kiln operations.

Mexico: Holcim México has mitigated 1.7Mt of CO₂ emissions in housing and infrastructure projects throughout the country in 2024, according to a press release, through its ECOPact, ECOPlanet and ECOCycle sustainable products.

Holcim’s ECOPact low-carbon concrete reduces CO₂ emissions by at least 30% and represents 15% of its concrete sales, with a target of 27% by 2027. Its ECOPlanet cement range reduces CO₂ emissions by 35-65% relative to traditional blends and accounts for 56% of cement sales, with a target of 77% by 2027. ECOCycle technology incorporates recycled construction and demolition materials into concrete for non-structural applications like pavements.

India: Titan Cement Group has entered the South Asian market through a joint venture with India-based supplementary cementitious materials producer JAYCEE. The producer will hold a majority stake in the new company Atlas EcoSolutions. The venture will source, process, market and distribute supplementary cementitious materials globally in order to help its customers build sustainable construction projects using alternatives to clinker-based cement.

Head of supply chain and energy development Jean-Philippe Benard said "This joint venture aligns perfectly with our strategy to remain at the forefront of low-carbon building materials and highlights our unwavering commitment to sustainability and innovation. Entering the South Asian market positions us in a region with vast potential, both in market demand and sustainability impact. Securing long-term access to SCMs provides Titan Group a key alternative for strategically diversifying its portfolio with new low-carbon cements."

Japan: Sumitomo Corporation has signed a memorandum of understanding (MOU) with US-based Fortera to conduct a feasibility study to build a low-carbon cement plant. The project will be run with subsidiary Sumitomo Osaka Cement. The aim is to then build a pilot plant in Japan by the 2026 financial year. Sumitomo Corporation is also considering expanding the business model developed in Japan to other parts of Asia.

UK: The Materials Processing Institute (MPI) is preparing to open its Sustainable Cement and Concrete Centre (SCCC) later in February 2025. The centre will focus on research and material development, including novel formulations for low-carbon cement and concrete and the use of electric arc furnace (EAF) slags in aggregates and clinker production. It will also provide consultancy services to further support clients to accelerate innovation, offering expertise and project management from concept through to pilot stage production.

The SCCC is a part of the EconoMISER programme, led by the Foundation Industries Sustainability Consortium (FISC), which aims to accelerate the decarbonisation of the UK’s so-called foundation industries. These include the cement, metal, glass, ceramic, paper, polymer and chemical sectors. The MPI is based in Middlesborough.

UK: Material Evolution has announced a partnership with ARC Marine for the use of its low-carbon cement in ARC Marine’s products. The companies intend to use Material Evolution’s MevoCem product across ARC Marine’s aquaculture, coastal defence and offshore energy portfolio. ARC Marine have accepted delivery of the first shipment of product to undergo testing in a marine environment. The partners will develop and test bespoke products tailored for subtidal and intertidal construction with the aim of scaling up production to include a wide-scale collaboration throughout in 2025 and beyond.

ARC Marine builds products that support artificial reefs and protect infrastructure like submerged cables and breakwaters. It has deployed over 2000 reef cubes into seven different countries. It says its reef cubes have provided a habitat for over 190 unique species.

France: Ecocem will build its first production facility dedicated to ACT, its low-carbon cement technology, at its Dunkirk site. The new site will be operational by 2026 with an initial capacity of 300,000t/yr of ACT.

The expansion will increase the plant's total production capacity to beyond 1Mt/yr and strengthen Ecocem’s operations in northern France, Paris and export markets. The first half of 2025 will see the installation of the key component of the facility, the mill, which will produce the required fillers, as well as expansion of blending and storage facilities. ACT is expected to be delivered to the market in the second half of 2026.

The total investment for the expansion is €50m, funded through a ‘green loan’ from the EthiFinance agency and supported by the French government and local authorities. France 2030's ‘Première Usine’ initiative also awarded a €3.6m grant, with additional grants from the Hauts-de-France Region and Dunkirk Urban Community.

Ecocem will partner with limestone supplier CB Green for the commercial production and delivery of ACT at the Dunkirk site.

UK: Cemvision has launched one of the UK’s first commercial applications of its low-carbon Re-ment cement technology at a STOREX self storage development in Sunbury, near London. The foundational slabs for the site employ Cemvision's Re-ment Massive product, which replaces traditional Portland cement. Recent laboratory tests have shown that the product achieves a 75% CO₂ reduction and a 28-day compressive strength, that reaches the C50/60 classification, compared to traditional Portland cement. STOREX and Cemvision have signed a Letter of Intent for further collaboration in the UK and other markets.

“This project is a landmark achievement for Cemvision as we bring the benefits of green cement to UK customers,” said Oscar Hållén, CEO of Cemvision.

Cemvision says that its Re-Ment Massive technology reaches different levels of CO₂ reduction depending on application and local conditions, with the product already having achieved more than a 95% reduction compared to Portland cement in demo production in the EU, according to the company.

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.
