France: Lafarge France has signed a memorandum of understanding with green hydrocarbons specialist Axens, utilities provider EDF and research firm IFP Energies Nouvelles for a synthetic fuel production trial. The partners will build a plant to produce kerosene using captured CO₂ from a carbon capture installation at Lafarge France's Saint-Pierre-La-Cour cement plant. The project, called Take Kair, aims to produce fuel for use by aviation companies, including Air France-KLM Group.

Holcim France president François Petry said "The decarbonisation of our processes and products is at the heart of our strategic commitment to reach Net Zero by 2050. Beyond the modernisation of our production tools, we work on all industrial and technological levers to reduce our emissions, and thus decarbonise our industry. With the Take Kair project, we are taking a decisive step in the capture and management of our residual CO₂ emissions and participate with our partners in the emergence of an innovative and sustainable sector serving the country's mobility needs."

Lafarge France, a subsidiary of Switzerland-based Holcim, announced a Euro40m investment in the 1.6Mt/yr Saint-Pierre-La-Cour cement plant to achieve carbon neutral cement production there in March 2022.

US: The Portland Cement Association (PCA) hosted a one-day session in mid-June 2023 aimed at establishing guidelines for the definition of 'low carbon' cement and concrete. The association called the session a 'Critical first step' towards ensuring clarity for stakeholders.

The PCA said "Low carbon is increasingly defined in the eye of the beholder, with little or no regard to either upstream and downstream impacts or short-term and long-term strength, durability and resilience concerns."

France: Ireland-based Ecocem has partnered with CB Green to launch a joint venture to scale up production of 70% reduced-CO₂ cement based on Ecocem's ACT technology. The technology combines widely available alternative raw materials into a product with enhanced strength and durability compared with ordinary Portland cement (OPC). The new joint venture will build a grinding plant in Dunkirk, Nord Department. The plant will produce 600,000t/yr of limestone filler for use in alternative cement production with ACT technology. The partners expect to invest Euro60m in the plant's construction, with commissioning scheduled for mid-2025.

Ecocem managing director Donal O’Riain said “This long-term cooperation agreement with CB Green marks a major milestone in our work to scale ACT, our low carbon cement technology, and deliver on our commitment to help the cement industry cost-effectively decarbonise by 50% by 2030. It secures production of fillers and access to high quality limestone, and is an important next step to ensuring that our ACT technology can be distributed at scale and start delivering on its potential to reduce CO₂ emissions by up to 70%. Technology is no longer the issue, scale and speed are what matters now."

UK: Mineral Products Association Lime (MPA Lime), the body representing the UK lime sector, has launched the Net Negative 2040 Roadmap. The association said that the roadmap sets out the strategy for its to 'go beyond net zero' by 2040. The industry will rely on the deployment of fuel switching, carbon capture, renewable energy sources and green transport technologies, among other approaches. It called on the government to support its aims through the implementation of carbon accounting, subsidisation of renewables and decarbonisation technologies, the development of green hydrogen infrastructure, ensuring that UK lime can remain competitive in the UK and overseas markets.

MPA Lime director Mike Haynes said “Each lever will contribute to decarbonisation – many initiatives are happening already or will come on stream this decade." He added "The combination of using biomass fuels with carbon capture and lime product carbonation will result in removal of 250,000t/yr of atmospheric CO₂, making the sector net negative overall. Other levers, especially indirect emissions and transportation, require broader collaboration and enabling action by government and other industries.”

Through their actions to date, MPA Lime members reduced their absolute CO₂ emissions by 25% between 2005 and 2022.

Saudi Arabia: Hoffmann Green Cement Technologies (HGCT) and property developer Shurfah Holding have signed a letter of intent to conclude a licensing agreement for use of HGCT’s technology by the state-owned construction firm. BusinessWire News has reported that HGCT plans to build four new units to produce its clinker-free alternative cement in Saudi Arabia. Construction will begin in 2024. Shurfah Holding said that the partnership signals progress towards the development of smart cities under the state’s Vision 2030 economic plan.

HGCT co-founders Julien Blanchard and David Hoffmann thanked Shurfah Holding and said that the partnership represents an acceleration in the producer’s international development.

Europe: Heidelberg Materials Northern Europe has signed a collaboration agreement with Volvo Group for an investigation into the use of electric vehicles in loading and hauling. Under the agreement, Heidelberg Materials Northern Europe will implement a mix of its electric trucks and construction equipment machines in its operations. Land-based transport accounts for 6% of the producer's CO₂ emissions. Through electrification, Heidelberg Materials Northern Europe expects to eliminate 200,000t/yr of CO₂ emissions.

Heidelberg Materials CEO Dominik von Achten said “The partnership with Volvo is a lighthouse project in our industry and has the potential to significantly push the decarbonisation of our entire value chain in northern Europe. We look forward to working together to identify and implement state-of-the-art solutions for a fast climate transition in the construction sector."

US: The government has awarded a US$3.24m grant to Washington State University (WSU) for its research towards the development of reduced-CO₂ cements. The research is investigating new formulations, in combination with novel technologies aimed at eliminating CO₂ emissions. WSU is one of 40 recipients of a funding pot worth US$135m.

Energy Secretary Jennifer Granholm said "America’s industrial sector serves as the engine of the US economy, producing many of the products we rely on every day, but it also produces a significant amount of the nation’s carbon emissions. These projects funded by President Biden’s Investing in American agenda will slash industrial emissions and accelerate next-generation technologies for a clean energy future that’s made in America.”

US: Heidelberg Materials North America inaugurated its 2.4Mt/yr Mitchell cement plant in Indiana on 14 July 2023. The plant is equipped with a 3600 bag/hr rotary packer, and also boasts a 154,000t-capacity clinker storage dome. It will produce Heidelberg Materials North America's EcoCem Portland limestone cement (PLC), alongside other products. The producer said that the new plant will help to address US cement supply chain constraints amid a planned US$110bn infrastructure overhaul.

Heidelberg Materials North America president and chief executive officer Chris Ward said "The plant will reduce CO₂ emissions per tonne of clinker by almost 30%, mainly through operating on natural gas. Our investment in the Mitchell facility helps us lower our carbon footprint, while serving the growing demand for more sustainable products in this key market.”

US: Holcim US has announced plans for a 25MW solar power plant to serve 75% of the electricity needs of its Alpena cement plant in Michigan. The company says that the installation at the Alpena plant will be the largest in the US Midwest Region. Holcim US chose NorthStar Clean Energy to build the array, which it says will eliminate 25,000t/yr of CO₂ emissions.

Other planned projects at the Alpena cement plant include an upgrade to the plant's dock in order to accommodate larger vessels and reduce the number of trips in its Great Lakes transport operations.

Holcim US' senior vice president, manufacturing, Michael Nixon said “As Holcim is showing in Alpena, the path to net-zero carbon emissions requires a blend of proactive solutions. Whether it’s using alternative fuels or implementing renewable energy from solar power, we are committed to reducing our reliance on fossil fuels — a goal that will benefit the environment as a whole and the Alpena community we have called home for more than 115 years.”

Europe: The European cement industry association, Cembureau, has welcomed the enactment of the Nature Restoration Law, which aims to restore ecosystems through binding targets in line with the EU Biodiversity Strategy. The European Commission says that the law provides a framework to 'secure the things nature does for free, like cleaning our water and air, pollinating crops and protecting us from floods,' as well as to help limit climate change to +1.5°C.

In a joint statement with other extractive industry bodies, Cembureau told the EU that member states' national restoration plans should take into account industry efforts to plan and implement nature restoration, that member states should protect pioneer species in line with the Nature Directives Species Protection Guidelines' definition of temporary nature and that restoration efforts outside of designated Natura 2000 areas should be addressed on a case-by-case basis in recognition of sectoral specificities.
