Greece: Ecocem has signed a partnership agreement with Titan Group to co-develop and deliver low-carbon cements using Ecocem’s ACT technology. The collaboration will initially target the Greek market, replacing a portion of clinker with locally sourced supplementary cementitious materials (SCMs) to reduce cement CO₂ emissions by up to 70%.

Group managing director Donal O’Riain said “Signing this co-development and technology transfer agreement with a partner of Titan Group’s size and calibre is a real demonstration of confidence in our ACT technology. This partnership has the potential to accelerate the use of a range of SCMs with ACT technology and deliver rapid and low-cost decarbonisation of the cement industry globally.”

France: CBMI has completed installation of a new rotary kiln at Eqiom’s Lumbres plant for the ‘K6 Project’. The plant is now reportedly carbon-neutral and is equipped with an oxyfuel kiln to reduce CO₂ emissions. The supplier said via social media that its team ‘delivered precise execution despite tight space and complex challenges’.

Eqiom announced back in 2024 that it would upgrade the Lumbres plant to expand its capacity and reduce emissions by 20% by 2026.

Australia: Boral will receive US$15.4m in government funding for a kiln feed optimisation project at its Berrima Cement Works, with CO₂ emissions expected to reduce by up to 100,000t/yr, based on predicted production rates. The Powering the Regions grant will support the producer’s installation of a new specialised grinding circuit and supporting infrastructure, which will raise the use of alternative raw materials in kiln feed to 23% from 9%, lowering the amount of limestone used.

Boral will use steel manufacturing by-products and industrial waste, including granulated blast furnace slag, steel slag, cement fibre board, fly ash and recycled fine concrete aggregates. The project will be operational in 2028.

The head of innovation and sustainability at Boral, Ali Nezhad, said “In terms of the resulting emissions intensity of the manufactured clinker, the project will result in up to 11% reduction in clinker emission intensity, 9% attributable to a reduction in calcination emissions and 2% attributable to thermal efficiency gains.”

China: NovaAlgoma Cement Carriers has confirmed an order for a 38,000t methanol dual-fuel pneumatic cement carrier by Zhejiang Xinle Shipbuilding, for delivery in 2027.

The vessel will be chartered under a long-term contract by Holcim. Other features include an air lubricating system and a waste heat recovery system, which will recycle exhaust gases to generate electricity.

“By increasing the quantity intake and burning green methanol, the CO₂ emissions on these shipments will be reduced by more than 60% per year in comparison to current freight flows, ie 0.18Mt of CO₂ reduction over a period of 10 years,” NovaAlgoma said.

Europe: 77 decarbonisation projects (including 14 for the cement sector) have signed grant agreements under the Innovation Fund 2023 Call (IF23), following the announcement of results in October 2024. The cement projects, spanning nine European countries, will begin operations between 2025 and 2029.

The funding, sourced from the EU Emissions Trading System, provides grants ranging from €4.4m to €234m, supporting projects expected to avoid 118Mt of CO₂. The total 77 projects funded have the potential to reduce emissions by around 398Mt of CO₂ equivalent over their first 10 years of operation. The projects funded in the cement industry mostly involve carbon capture and storage (CCS). Among the selected CCS projects are Carbon2Business in Germany, Olympus in Greece, Go4Zero in Belgium and Cementir’s Accsion project in Denmark.

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.

US: California Resources Corporation and its carbon management subsidiary, Carbon TerraVault (CTV), have signed a memorandum of understanding (MoU) with National Cement Company of California to develop the ‘Lebec Net Zero’ project, which will produce carbon-neutral cement at National Cement’s Lebec facility in Kern County, California.

CTV will provide transportation and sequestration solutions for up to 1Mt/yr of CO₂ emissions captured from the Lebec plant. The captured CO₂ will be transported and stored in CTV’s underground storage reservoirs. The project will integrate carbon capture technology, use locally sourced biomass fuel from agricultural byproducts and produce limestone calcined clay cement (LC3).

Pending customary approvals, operations are expected to commence in 2031.

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.

Global: Global Cement and Concrete Association (GCCA) has launched the Innovandi Open Challenge 2025, inviting start-ups to wok together with cement manufacturers around the world in developing low carbon concrete technologies.

The Open Challenge is looking for start-ups working on next generation materials for net zero concrete, including low-carbon admixtures, supplementary cementitious materials, activators or binders. The challenge aims to find ways to reduce clinker use and incorporate new materials to lower CO₂ emissions.

The programme follows three previous Open Challenges.

Chief executive Thomas Guillot said "Advanced production methods which are decarbonising our sector are already being used in cement and concrete production in many parts of the world. Through the Innovandi Open Challenge, start-ups can bring in even newer ideas and further accelerate our industry's push."

“If you are a start-up from anywhere in the world with an innovative idea or technology, then we want to hear from you."

Start-ups can find more information and apply to take part in the Innovandi Open Challenge by going to the GCCA Open Challenge 4 webpage: Innovandi Open Challenge 4 : GCCA

Europe: Sweden-based SaltX has signed a letter of intent with German engineering firm thyssenkrupp Polysius to collaborate on establishing 100% electric cement production facilities in Europe. The facilities will combine SaltX’s electric arc calciner (EAC) technology with thyssenkrupp Polysius’ material handling solutions.

CEO of SaltX Lina Jorheden said "Strong partnerships are essential for us to effectively implement our technology and reduce millions of tonnes of CO₂ emissions from the industrial sector. Our collaboration with thyssenkrupp Polysius is crucial for developing complementary systems to the EAC technology and building electrified facilities for our customers."
