Northern-Ireland based cement producer Cemcor said this week that it has completed trials of a calcined clay cement product called CalcinX. The company started its trials in 2023 and it has been supported by Queen’s University Belfast and funding from Innovate UK. Work with commercial partners has involved precast concrete paving manufacturer Tobermore producing paviours made from 50% CalcinX as a CEM II replacement and Moore Concrete has also manufactured precast units using 50% CalcinX as a CEM I replacement. So far over 3000t of CalcinX has been produced in a number of industrial-scale trials.

David Millar, the managing director of Cemcor, mentioned his company’s plans for calcined clay in June 2022 when he was interviewed by Global Cement Magazine. The company that became Cemcor bought the Cookstown cement plant and a few other assets from Holcim at the start of 2022. It then changed its name to Cemcor in November 2022. At the time of the interview the company was looking to “...develop new value-added products, including low-CO₂ options. This will allow us to use the same amount of clinker to produce more cement.” Millar couldn’t give away too many details at the time, however calcined clay was cited specifically. It was also noted that the company had the right material in its quarry and that it was already working with partners on it.

Amongst all the other decarbonisation options available for cement plants, a slow trickle of calcined clay projects keep being announced. In January 2025, for example, thyssenkrupp Polysius said it had secured a front-end engineering design contract from Circlua for the construction of the world’s largest activated clay plant in Brazil. This project in Para state will have a capacity of 3000t/day, will use renewable energy sources and will “improve the CO₂ footprint in cement production.” CBMI Construction also officially launched a flash calcination clay project in Tangshan, Hebei province in China. In December 2024, Vicat signed an agreement with the US Department of Energy (DOE) Office of Clean Energy Demonstrations to develop the Lebec Net Zero (LNZ) project at its Lebec cement plant in California. This includes plans to produce calcined clay-based cement. Earlier in the autumn of 2024 Portugal-based Cimpor said it was preparing to convert a kiln at its Souselas plant to produce calcined clays, AVIC International Beijing and KHD said that they had secured a deal to build a 900t/day clay calcination plant for Ciments de l'Afrique (CIMAF) in Burkina Faso, and Holcim Česko said it was going to construct a calcined clay processing line at the Čížkovice cement plant in the Czech Republic.

One news story that stuck out in the autumn was the progress of a collaboration between Aumund and Holcim towards developing an electric linear calcination conveyor (eLCC). The two companies started work on the project in 2020 intending to look at the electrical calcination of clay using an Aumund pan conveyor. Initial tests of the eLCC reportedly demonstrated efficient thermal activation of clay through a combination of radiant heat and material circulation. The eLCC system is fully enclosed, insulated, has a compact design and can operate using electrical-powered renewable sources. The first industrial plant utilising this technology is scheduled for construction in 2025. Calcined clay technology and products by other industrial suppliers are available. The work by Aumund and its competitors show they are watching this market closely.

OneStone Consulting’s Joe Harder has found that only 14 clay calcination plants were operational worldwide in 2023 with a production capacity of just under 3.5Mt/yr. These are based in Latin America, Europe and Africa. In an article previewing a market report in the February 2025 issue of Global Cement Magazine, Harder predicts that by 2035 there will be 79 clay calcination plants with a capacity of just under 21Mt/yr. A steady growth of over 20 new plants annually is also expected subsequently from 2035 to 2050 as cement producers seek cost-effective ways to reduce their clinker factor. He identified installation costs, a lack of knowledge about clay-based cements, trouble obtaining mining rights and policy issues amongst other issues as holding back the use of clay calcination.

The current expectation is that calcined clay usage in the cement industry will be a minority option. Yet the size of global cement production can make a production share of, say, 3 - 8% a viable option for both cement manufacturers and equipment suppliers. The adoption of new cement products and standards can also take a long time and this clouds predictions of how far clay can go in the cement industry. At this point in the calcined clay story it is time to keep track of the new projects being set up.

Joe Harder will present a talk entitled ‘Calcined clay market trends by 2035’ at the Global FutureCem Conference taking place in Istanbul in early February 2025

Türkiye: Two members of the cement sector have reportedly died in a fire at the Bolu Kartalkaya Ski Center. Aysemin Elif Dogan, Mehmet Cem Dogan and their daughter perished in the incident, according to posts by their employers on LinkedIn. 76 people have so far reported to have been killed.

Aysemin Elif Dogan was the R&D and Quality Director for Baştaş Çimento, a subsidiary of France-based Vicat.

Mehmet Cem Dogan had been the plant manager of OYAK Çimento’s Bolu plant in Caydurt since 2023. Prior to this he was the manager of a plant in Ankara. Dogan previously worked for Vicat’s subsidiary Baştaş Çimento and Cimpor in process engineering and production management roles.

US: Vicat subsidiary National Cement Company of California has signed a cooperative agreement with the US Department of Energy (DOE) Office of Clean Energy Demonstrations to develop the Lebec Net Zero (LNZ) project at its Lebec cement plant in California.

The agreement commits up to US$500m, covering up to 50% of the Phase one cost. The project includes constructing a CO₂ sequestration facility with a 0.95Mt/yr capacity, enabling the plant to capture ‘almost all’ of the plant’s emissions. It will also increase alternative fuel use from locally sourced biomass and reduce the plant’s clinker factor by producing calcined clay-based cement. The plant will reportedly produce carbon-neutral cement.

The first step will be to conduct a preliminary engineering study and establish a community advisory body in charge of relations with local communities. Phase one will run through the first quarter of 2026.

Germany: Heidelberg Materials has appointed Gün Burak Günbey as Senior Project Manager at its Competence Center Cement global research and development hub.

Günbey has worked for the cement sector since the late 2000s. He has held engineering, project management and investment roles at OYAK Bolu Çimento, Limak Cement and Vicat. He became the Group Investment Manager for Vicat Group Türkiye in 2021 and subsequently worked as Project Expert for VICAT Senegal Sococim from 2023.

Germany: The European Cement Research Academy (ECRA) has elected Eric Bourdon as the chair of its Technical Advisory Committee. Hendrik Möller, Schwenk Deutschland and Samir Cairae, Titan Cement have also joined the organisation’s board of directors

Bourdon is the Deputy CEO, the Head of Industry and the Chief Climate Officer of Vicat. He joined the group in 2002 after working for thyssenkrupp Polysius. He is a graduate in engineering from the Ecole Nationale Supérieure d’Arts et Métiers in Paris.

ECRA was founded in 2003. It supports and shares research by the cement sector in Europe. It is steered by its technical committee. Bourdon will work with ECRA managing director Martin Schneider on strengthening its work in strategic areas, including CO₂ capture and related technologies, as well as grinding and kiln technologies.

Energy has been the theme for a couple of cement news stories of note from Egypt this week. The first concerns the government’s impending plan to centralise distribution of mazut (heavy fuel oil) to cement plants to help them cope with ongoing power shortages. Earlier in the week Cemex signed a deal with the Assiut Governorate to operate a second municipal solid refuse processing unit in the country. The company’s first Regenera facility, in Mahala, started operations in May 2024. Another story from mid-September 2024, along the same theme, covered the inauguration of an 18MW waste heat recovery (WHR) unit at Heidelberg Materials Egypt's Helwan Cement plant.

The wider story is that the country has faced so-called load shedding, or power rationing, since mid-2023 due to falling gas production, rising energy demand and negative currency exchange effects making it harder to buy fuel imports. The power cuts were extended in duration in July 2024 due to a heat wave. The government then said in late September 2024 that it is making investments to prevent domestic power cuts in 2025.

The cement stories mentioned above show some of the ways cement companies cut their energy costs. Two potential ways of doing this are to increase the use of alternative fuels (AF), such as municipal solid waste, or to install a WHR unit. Titan Cement, for example, reported AF thermal substitution rates of above 40% in Alexandria and above 30% in Beni Suef in the first half of 2024. The local press hasn’t reported power shortages amongst the country’s cement producers, but the plans to control the distribution of mazut suggest that either ‘something’ has happened or the government is trying to avoid ‘something.’ Readers may recall that producers have periodically faced step changes in power supplies over the years. In the mid-2010s, for example, lots of plants switched from heavy fuel oil and gas to coal. The energy price fluctuations following the start of the Russia - Ukraine war in 2022 then saw the price of coal rise.

However, what the foreign-owned producers have complained about in the first half of 2024 is the declining exchange rate of the Egyptian Pound. Cementir, Cemex and Titan Cement all noted this. However, Titan reckoned that International Monetary Fund and European Union investment had actually eased the economic situation in the first half of the year leading to an increase in the number of large construction projects.

One effect of the currency problems upon the cement market has been a focus on exports. At the start of September 2024 the Federation of Egyptian Industries said that national cement consumption in 2024 was expected to drop by 4% year-on-year to 45Mt. However, exports were projected to rise to 15Mt. The first and second most popular destinations so far in 2024 have been the Ivory Coast and Ghana. Yet, exports to Libya, the third biggest external market, may have had the biggest effect. These have been blamed for creating a shortage of trucks that was causing delays to the local construction sector. The round-journey from Egypt to Libya can take up to 12 days. This has left building sites bereft of raw material deliveries because all the trucks are elsewhere! Vicat acknowledged the growing importance of imports for its business in Egypt in its half-year report for 2024. It said that ‘sluggish’ domestic market conditions “were more than offset by growth in cement and clinker volumes for export to the Mediterranean and Africa regions.”

The wider picture of the cement sector in Egypt remains one of overcapacity with integrated capacity estimated above 70Mt/yr. The government introduced cement production quotas in mid-2021 and this stabilised prices (and profits). The recent state of the local economy may have strained this, but the latest round of external investment appears to have buoyed things for now. Although the effects of the Israeli military action in Lebanon may have unforeseen consequences upon neighbouring markets. In the meantime, cutting energy costs and growing exports offer two ways for producers to raise their profits.

France: Vicat’s results for the first half of 2024 showed a turnover of €1.94bn, up by 1.3% compared to the same period in 2023. Earnings before interest, taxation, depreciation and amortisation (EBITDA) for the period increased by 12% year-on-year. The group expects 3 – 8% growth in full-year EBITDA in 2024. Despite an unfavourable exchange rate effect, mainly due to the depreciation of the Turkish and Egyptian Pounds against the Euro, consolidated net income rose by 5% year-on-year to €115m.

Heidelberg 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.

The 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).

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.

France: Vicat recorded consolidated sales of Euro3.94bn in 2023, up by 8% year-on-year from Euro3.64bn in 2022. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) were Euro740m, up by 30% from Euro570m. The producer's energy costs declined by 10% to Euro596m. Vicat noted ‘strong’ growth in sales across all regions except Kazakhstan and India, and in earnings in the US. Its cement volumes rose by 6.3% overall, but contracted in Egypt, France, Senegal and Switzerland.
