Update on France, April 2024
10 April 2024Heidelberg Materials announced this week that it is preparing to close its integrated cement plants at Beffes and Villiers-au-Bouin in France by October 2025. It framed the restructuring as a response to ‘a significant decline in cement sales in France’ and a plan to focus on low-carbon products. Unfortunately, local media reported that around 170 jobs will be lost at the two sites. The company says it is looking at ‘socially acceptable solutions’ including redeployment to other locations in the country.
Investment has been forthcoming from Heidelberg Materials France in recent years. It reminded everyone that it initiated a Euro400m scheme at its France-based subsidiary Ciments Calcia in late 2020. Most of this was earmarked towards a new production line at the Airvault plant, which is currently being built. Other schemes at the Beaucaire, Bussac-Forêt and Couvrot integrated plants followed. More recently, Heidelberg Materials launched a carbon capture, utilisation and storage (CCUS) project at Airvault, part of the GOCO2 initiative, with the aim of starting initial capture in 2030 with full 1Mt/yr capture planned later. What the company didn’t mention though was at the time of that 2020 investment it was also preparing to convert the integrated Gargenville plant into a grinding unit, stop white cement production at its Cruas plant with the intention of turning the site into a terminal and it wanted to reduce its workforce by around 140. To be fair to Heidelberg Materials though, it did have the same goal of reducing its specific net CO2 emissions. The added detail this week was that the group aims to generate half of its revenue from sustainable products that are either low-carbon or circular by 2030.
Heidelberg Materials France is not alone with its ambitions for low-carbon products. Holcim notably opened in early 2023 what it said was the first calcined clay unit in Europe at its Saint-Pierre-la-Cour cement plant. Heidelberg Materials then followed in May 2023 with the announcement of a calcined clay project at its Bussac-Forêt cement plant. Other clay projects from Vicat, NeoCem and Neo-Eco have been reported since then. The other prominent France-based blended cement producer that has steadily been building its business in recent years is Hoffmann Green Cement. More general plant upgrade projects that are also worth mentioning include Eqiom’s (CRH) upgrade to its Lumbres plant in February 2024 and the ignition of a new kiln at Lafarge France’s Martres-Tolosane plant in October 2023. Both of these projects have been framed as driving sustainability.

Heidelberg Materials’ assessment about the poor state of the cement market has been confirmed by local media. Sales reportedly started falling in 2022, were down by 6% year-on-year in 2023 and further downward pressure is expected in 2024. Production data shown in Graph 1 above released by France Ciment, the national cement association, doesn’t really show what has been happening with sales. Over the last 20 years production hit a high of around 22Mt in the mid-2000s before settling around 16 - 17Mt/yr from 2015 onwards. The more telling trend, perhaps, has been the increase in CEM II blended cements from 50% in 2012 to 64% in 2022. Cement production may have stayed roughly the same over the last decade but it is using less clinker than it used to. Hence the pressure on companies like Ciments Calcia to reduce clinker capacity.
A further cost pressure facing cement producers in France is the impending end to the price cap on electricity scheduled by the end of 2025. The government enacted the scheme in late 2021 at the end of the Covid-19 pandemic, but then carried on as energy prices spiked following the Russian invasion of Ukraine. France Ciment lobbied in August 2023 for further protection for the sector using the argument that decarbonisation was not possible without electricity available for a reasonable price. It added that decarbonising the cement sector in France with carbon capture would cost around Euro3.5bn. Electricity prices started rising in February 2024 as part of the government’s phase out of the scheme.
Finally, 17 people were arrested on 5 April 2024 in connection with a demonstration at Lafarge France’s Val-de-Reuil ready-mixed concrete plant in Eure. Environmental activists reportedly trespassed on the site, according to local press, causing an estimated Euro450,000 in damages with acts such as spraying foam into machinery, ripping up bags of cement, breaking windows and more. The activists presented their actions as a response to both the environmental impact of cement and concrete production and the ongoing legal allegations about Lafarge’s actions in Syria in the early 2010s. Lafarge France’s La Malle integrated plant was also similarly targeted in December 2022 when around 200 activists stormed the site and caused damage to machinery and property. Lafarge’s response at the time was to remark that there was a feeling of misunderstanding given that the La Malle plant was piloting various decarbonisation methods.
All of this presents a febrile picture of the cement sector in France. Sales are down, electricity costs are set to go up and producers are switching to low-carbon cement products. Alongside this they are also closing clinker production plants but are also investing in new decarbonisation projects. At the same time environmental protestors have also been targeting cement and concrete plants and Lafarge’s association with its former actions in Syria appear to have made it more of a target than the other manufacturers. It is unsurprising then that Holcim, the parent company of Lafarge France, has raised the risk of damage to the group’s reputation, with both the general public and investors, should it fail to meet its targets. Reaching net zero was never going to be easy but setting unrealistic targets is increasingly not an option.
Decarbonising the cement sector in the US, March 2024
27 March 2024The US Department of Energy (DOE) announced a US$1.6bn investment in the cement sector this week. The funding was part of a total of US$6bn for 33 projects in over 20 states to decarbonise energy-intensive industries also including chemicals and refining, iron and steel, aluminium and metals, food and beverages, glass, process heat applications and pulp and paper. The DOE was keen to link the money to “the President’s Bipartisan Infrastructure Law and Inflation Reduction Act.” Politics is never far away it seems! The projects are part of the Industrial Demonstrations Program, managed by DOE’s Office of Clean Energy Demonstrations (OCED).
Company | State | Funding | Scale | Method |
Heidelberg Materials US | Indiana | US$500m | Full | CCS |
National Cement | California | US$500m | Full | Alternative fuels, calcined clay, CCS |
Summit Materials | Georgia, Maryland, Texas | US$216m | Demonstration | Calcined clay |
Brimstone Energy | TBD | US$189m | Commercial | Raw material substitution |
Sublime Systems | Massachusetts | US$87m | Commercial | Raw material substitution |
Roanoke Cement | Virginia | US$62m | Demonstration | Calcined clay |
Table 1: Summary of US Department of Energy funding announced on March 2024 to decarbonise cement and concrete production
Table 1 above shows the main approaches each of the projects aim to use. The two most expensive ones involve carbon capture and sequestration (CCS) at Heidelberg Materials US’ Mitchell cement plant in Indiana and National Cement’s Lebec plant in California respectively. In a complimentary press release Chris Ward, the CEO of Heidelberg Materials North America, said “This substantial federal funding investment will help create the first full-scale deployment of carbon capture and storage on a cement plant in the US.” The proposed CCS unit at the plant will capture around 2Mt/yr of CO2 from 2030. If Ward’s forecast is accurate (and no one beats them to it), then Heidelberg Materials will likely have set up the first full-scale CCS units at cement plants in both North America and Europe. This will be a significant achievement. The National Cement project, by contrast, is a mixed bag of approaches to decarbonising cement production that follows the multi-lever approach advocated for in many of the industry net-zero roadmaps. It intends to use agricultural by-products such as pistachio shells, as alternatives fuels to lower the fuel-based emissions, calcined clay to lower the clinker factor and CCS to capture the remaining 950,000t/yr of CO2 emissions.
The other projects either involve using calcined clay or substituting limestone with calcium silicate. The Summit Materials proposal is noteworthy because it aims to build four clay calcination units in locations in Maryland, Georgia and Texas. None of these appear to be near Summit’s (or Cementos Argos’) cement plants. This suggests that the company may be intending to use calcined clay in ready-mixed concrete production. The Roanoke Cement Company calcined clay project will be baseEuropead at its cement plant in Troutville, Virginia.
The remaining two grant recipients, Brimstone and Sublime Systems, will both test the companies’ different methods of manufacturing cement by using calcium silicate instead of limestone. Brimstone’s method produces ordinary Portland cement (OPC) and supplementary cementitious materials (SCM). The company said in July 2023 that its OPC met the ASTM C150 standards. However, the company has released less information about its actual process. Sublime Systems’ uses an electrolysis approach to create its ASTM C1157-compliant cement. It calls this ‘ambient temperature electrochemical calcination.’
Investment on the same scale of the DOE has also been happening in Europe. In July 2023, for example, the European Commission announced an investment of Euro3.6bn in clean tech projects to be funded from the proceeds of the European Union emissions trading scheme (ETS). This was the third call for large-scale projects following previous announcements of recipients in 2021 and 2022. Euro1.6bn of the third call funding went towards cement and refining projects including five cement and lime projects in Belgium, Croatia, Germany and Greece. The money granted for each of these schemes was in the region of Euro115 - 235m.
Both the US and Europe are throwing serious finance at the cement industry to try and kickstart the various pathways towards net zero. They are also doing it in different ways, with the US aiming to boost its economy by onshoring sustainable industry, and Europe hoping to fund its approach via carbon taxation. Government-driven decarbonisation investment for cement in other large countries and regions around the world appears to be lagging behind the US and Europe but these may spring up as net zero targets are set, roadmaps drawn up and government policy formulated. These places could also benefit from watching what works and does not work elsewhere first. Back in the US and Europe the next tricky part of this process will be bridging the gap between government subsidy and commercial viability.
US: The US Department of Energy has selected four cement producers to receive funding under the Bipartisan Infrastructure Law and the Inflation Reduction Act.
Heidelberg Materials US secured up to US$500m for its planned 2Mt/yr carbon capture project at the Mitchell cement plant in Indiana. National Cement also received up to US$500m, for its Lebec Net Zero limestone calcined clay cement (LC3) project in California. Summit Materials received up to US$216m for a series of clay calcination projects in Georgia, Maryland and Texas. Lastly, Roanoke Cement will receive up to US$61.7m for an LC3 project at its Troutville cement plant in Virginia. These projects also involve developing a training, education and certification consortium in the cement sector.
Portland Cement Association (PCA) president and CEO Mike Ireland said "This funding is a welcome acknowledgement from the government that America's cement manufacturers are taking ambitious and significant steps toward reaching carbon neutrality. This will move the needle closer to achieving what industry considers the 'heavyweight' of carbon solutions: carbon capture utilisation and storage (CCUS). Once established nationwide, CCUS will greatly accelerate cement manufacturers' charge toward net zero."
Senior vice president of government affairs Sean O'Neill added “From passage of the Bipartisan Energy Act of 2020 to securing funding through the Inflation Reduction Act and the Infrastructure Investment and Jobs Act, today's announcement is another major milestone in the cement industry's decarbonisation efforts. The PCA is committed to continuing to work with policymakers to ensure the regulatory environment facilitates rather than impedes these and future investments.
Switzerland: ABB and Captimise have enhanced their collaboration, focusing on advancing cost-effective carbon capture, utilisation, and storage (CCUS) technologies in the cement industry. Under a new Memorandum of Understanding, the partnership will develop various studies, including screening, feasibility, and FEED, aiding cement producers to identify efficient carbon capture solutions across their operations. The joint effort is expected to bolster the cement industry's efforts to meet its climate and net-zero targets.
CEO of Captimise, Mattias Jones, said “We draw on a track-record of more than 25 live case studies with CO₂ emitters across Europe and the US and know we’ll be able to support operations of all sizes in cement through combined CCUS, automation and electrification technologies.”
Global Business Unit Manager at ABB Process Industries, Max Tschurtschenthaler, said “Reducing the CO₂ emissions from cement manufacturing is a major challenge and a top priority for this industry. We are on a mission to make it more cost-effective. By combining our world-class automation, electrification and digital technologies with the know-how of partners like Captimise, we can further support the cement industry in achieving their climate and net zero targets.”
Cemsuisse urges CBAM adjustment for cement industry
25 March 2024Switzerland: The decision of the Swiss government in June 2023 against the implementation of a Carbon Border Adjustment Mechanism (CBAM) has been strongly criticised by the Swiss cement association, Cemsuisse. The association warns of a potential relocation of the Swiss cement industry without such a mechanism, referencing a report by Polynomics. This report concludes that a Swiss CBAM is necessary to level the playing field with EU and non-EU cement suppliers. The EU initiated a CBAM test phase in October 2023, aiming to mitigate production relocation risks to countries with less stringent environmental regulations.
The federal government concluded that a CBAM in Switzerland would benefit few emission-intensive industries at the expense of the wider economy, while also facing regulatory and trade policy risks. It plans to reassess the need for a CBAM in mid-2026, in line with the EU's interim CBAM report.
Cemsuisse, referencing the Polynomics report, states that waiting to potentially introduce a CBAM in Switzerland is not an option. Investments in carbon capture and storage (CCS) are deemed essential for Switzerland's net-zero climate goal and without a CBAM, there is a risk of these investments being unviable due to uncertainty over cost recovery.
The report also points to the risk of increased clinker imports from third countries into the EU, which would be processed and then exported to Switzerland without CBAM levies. As an example, Cemsuisse mentions a planned milling station in Ottmarsheim, Alsace. It says that without a CBAM, the production site in Switzerland faces serious threats.
Cemsuisse said “Without CBAM, this certainty is lacking. And without CCUS, long-term production in Switzerland won't be viable. The population has accepted the climate protection law last summer, where the net-zero goal is legally anchored."
UK: Capsol Technologies has been selected to conduct a study on its carbon capture technology at Aggregate Industries Cauldon cement plant in Staffordshire. Owned by the Holcim Group, the company’s plant will undergo a feasibility study by Capsol Technologies for its CapsolEoP® carbon capture system. The potential for carbon capture at this plant is 600,000t/yr of CO₂. The CO₂ captured will be stored geologically through the nearby MNZ Cluster or HyNet North West.
CCO Johan Jungholm said “CapsolEoP® provides a cost-efficient carbon capture solution for cement, and our solution can be run on electricity alone without expensive heat integration or external steam supply. It offers flexibility in the optimisation of the designs, allowing for high capture rates, high reliability and low energy consumption."
The contract includes supplier input for the feasibility study, and further pre-FEED engineering if Capsol's technology is selected. The UK Government's Industrial Energy Transformation Fund (IETF) is funding the study, with Petrofac as Aggregate Industries engineer. This study is part of Peak Cluster's objective to reduce over 3Mt/yr of CO₂ from cement, lime, and refuse facilities by 2030. Capsol Technologies is focusing on the cement industry, which accounts for about 8% of global CO₂ emissions.
Sustainable concrete project launched in Rome
21 March 2024Italy: Scientists Gregory Chass and Kun Tian have developed a sustainable concrete from wet waste materials through their company Mesoscale Engineering Halcyon. This 'green concrete' concept was conceived in Garbatella and will first be tested on the district's pavements. The concrete, made by combining and recycling industrial CO₂ emissions with brine from saltworks, is part of the Clean Energy Transition Partnership. It is also central to the BUCK$$$ project, led by Kun, focusing on carbon capture and utilisation. This project, with €2.54m in funding, involves 13 partners from seven countries.
This innovative concrete arises from 'mineralised CO₂', which is similar to mollusc shells made of calcium carbonate, as well as materials derived from saltwork brine, desalination, and industrial wastewater. Both currently underused products are expected to become crucial in the cement and concrete industries, particularly in Italy.
Germany: According to a new study backed by the German Cement Works Association (VDZ), the country's cement and lime industries require carbon capture and storage (CCS) for decarbonisation. The study outlines the need for a 4800km CO2 transport pipeline in Germany by 2035.
The VDZ warns that any delay could jeopardise Germany's 2045 climate neutrality target and estimates the investment for the new CO2 grid at €14bn. The network is expected to transport 6.5Mt/yr of CO₂ by 2030, increasing to 46Mt by 2045. Additionally, CCS transit from Switzerland, Austria and France is expected to contribute 15 - 20Mt.
VDZ president Christian Knell said "Cement manufacturers and other industries in the EU emissions trading system must produce largely climate-neutrally by 2040."
Heidelberg Materials France to trial carbon capture installation at Airvault cement plant
13 March 2024France: 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.”
