France: Heidelberg Materials France plans to install a 1Mt/yr carbon capture system at its Airvault cement plant in the New Aquitaine. The Airvault cement plant is undergoing an upgrade, including the replacement of two pre-existing semi-dry lines with a new dry line and pre-calciner. This will reduce the plant’s CO₂ emissions by 30% per tonne, reduce its energy consumption by 10% per tonne, reduce its clinker factor and raise its alternative fuel substitution rate to 90%. CO₂ capture is set to commence in 2030. The project is one of several, under the GOCO₂ carbon capture, storage and utilisation (CCUS) cluster, which also includes installations at Holcim France’s Saint-Pierre-La-Cour plant and Lhoist France’s Réty lime plant.

Chair Dominik von Achten said “We started an ambitious modernisation programme for our sites in France several years ago, with a planned investment of more than €400m. With the integration of AirvaultGOCO₂, we are now adding a cutting-edge project in the field of carbon capture to our previous efforts, which will enable a further, massive reduction of Heidelberg Materials’ carbon footprint in France.”

Chief sustainability officer Nicola Kimm added “Our approach in Airvault is a perfect example of Heidelberg Materials’ strategy to implement dedicated carbon reduction roadmaps. We are taking every possible step to reduce CO₂ emissions: Phasing out fossil fuels, reducing the clinker content of our cements, and improving energy efficiency. To mitigate the remaining residual emissions, we rely on CCUS – as part of an integrated scheme and with our strong partners in GOCO₂.”

Switzerland/Sweden: ABB and Sweden-based Salt X have agreed to develop Electric Arc Calcination (EAC) technology, with ABB also becoming a Salt X minority shareholder. This partnership aims to decarbonise cement production and similar industries by replacing fossil fuel-based heating with renewable energy and CO₂ capture during calcination. ABB will enhance the EAC with control and electrical systems, contributing to the technology's commercialisation.

Salt X CEO Carl-Johan Linér said "This strengthens us as a company and enables us to progress with our growth plans. With ABB and our other partners, we can significantly improve our capability to take a leading role in the electrification wave sweeping through the industrial sector.”

ABB's Global Growth Industries Business Line Manager Michael Marti said, "Our collaboration with Salt X marks a significant milestone in this journey. The technology benefits are two-fold; replacing the use of fossil fuels through renewable electricity in the calcination process and enabling cost efficient capture of the carbon emissions at the same time. It will be a highly effective way of curbing lime production emissions.”

Global: The Green Cement Technology Tracker, launched by the Global Cement and Concrete Association (GCCA) and the Leadership Group for Industry Transition (LeadIT), has expanded its scope to include calcined clay production, a significant step in cement industry decarbonisation. This tool, vital for tracking progress towards net zero emissions, initially focused on various decarbonising technologies and has now broadened to cover calcined clay kilns, which have lower energy requirements and CO₂ reduction potential.

LeadIT Head Per Andersson said “In order to empower the industry and policymakers committed to emission reductions, our goal is to provide comprehensive tracking of public announcements of investments in low-carbon cement technologies.”

GCCA’s Cement, Innovation and ESG Director Claude Loréa said “Driving down emissions requires investment in new technologies and production methods and incorporating calcined clay can contribute significantly, making it a valuable strategy for sustainable construction.”

Canada: Holcim North America has introduced ECOAsh, a Type F fly ash reclaimed from landfills, within its Lafarge Western Canada operations. This innovation is part of Holcim's commitment to sustainable building materials and represents a significant stride in decarbonising the construction industry. As the shift away from coal-fired power plants continues, addressing challenges related to sourcing reliable fly ash supplies prompts the exploration of harvesting and beneficiating legacy landfilled ash as a viable replacement.

Toufic Tabbara, Regional Head of Holcim North America, said "As we continue to build to support growing population demands, the integration of circular building materials such as ECOAsh plays a crucial role in driving our portfolio towards a more sustainable future.”

Brad Kohl, President and CEO of Lafarge Western Canada, added "The transformation of landfill materials into high-value fly ash for sustainable building presents an exciting opportunity for our customers and us to build more with less and work towards a net-zero future.”

Holcim and Geocycle's new processing facility in Alberta will produce high-quality, specification-grade fly ash. The ECOAsh processing facility, commissioned in February 2024, will commence the production and distribution of products throughout Western Canada in the first quarter of 2024.

Denmark: A collaborative effort involving the Technological Institute, DTU, FLSmidth Cement, and Lhoist is underway in Denmark to test a new technology designed to significantly reduce CO₂ emissions in the cement industry. The initiative, known as the Newcement project, is part of the INNO-CCUS partnership which embraces projects focusing on carbon capture, utilisation and storage (CCUS) and is supported by an investment of US$1.12m from the Innovation Fund. Jens Christiansen, Section Manager at the Technological Institute and Project Manager of the collaboration, aims for the technology to move from laboratory tests to a full-scale demonstration in a real cement production plant.

France: Fives Group has partnered with Holcim to decarbonise its cement production processes. Fives conducted successful hydrogen tests at the La Malle site in France, achieving over 50% hydrogen substitution in cement production. This result also enabled a significant increase in the use of alternative fuels while still maintaining cement quality. The group has also developed a digital model to tailor this process to each cement plant's unique requirements.

India: UltraTech has installed floating solar photovoltaic panels at its Awarpur Cement Works plant on two water reservoirs, spanning 3600m². The reservoirs contain 7600 panels in total, which will generate 6173MWh/yr of solar energy. This initiative will reduce CO₂ emissions by 6000Mt/yr, equivalent to the sequestration benefits of 270,000 trees. The project enables UltraTech to use 100% of the generated power. Additionally, it will reduce water evaporation by up to 70% and has a minimal impact on local ecosystems.

France: Representatives from the global cement and concrete industry will meet in Paris on 7- 8 March 2024 for the Global Buildings and Climate Forum. Industry leaders will seek to set out a framework for sustainable, decarbonised buildings.

Global Cement & Concrete Association CEO Thomas Guillot said “Our industry has been leading the way on decarbonisation through the implementation of our 2050 Net Zero Concrete Roadmap, and as our Roadmap sets out we are committed to fully decarbonising this essential material.”

Bruno Pillon, Chair the French cement association France Ciment, said “France and the whole world will still need to rely on cement and concrete for future infrastructure. But it’s really important that the cement and construction sectors, governments and suppliers all work together to achieve our net zero goal.”

Germany: Australia-based Calix confirmed that its LEILAC-2 project will take place at Heidelberg Materials’ cement plant in Ennigerloh, Germany. This follows Heidelberg Materials' decision to cease clinker production at its Hanover cement plant. The project, which aims to capture CO₂ emissions from cement production, already has a system design ready for construction at Ennigerloh.

LEILAC CEO Daniel Rennie said "The LEILAC technology represents a scalable and economical solution to address the carbon dioxide emissions produced unavoidably by the cement and lime industries, and the rapid demonstration of such solutions is essential to achieving our industrial decarbonisation goals."

Belgium: Heidelberg Materials Benelux will invest €450m in its Anthemis project, involving the installation of an 800,000t/yr carbon capture system, at its Antoing cement plant. The project is scheduled for completion in 2029. Captured CO₂ will travel by pipeline to the North Sea for storage.
