The release of the half-year financial results from many of the larger multinational cement producers in Europe and North America gives us the usual opportunity to examine how well the year has gone so far. In summary, each of the companies highlighted here increased its sales and earnings on a like-for-like basis. However, in many cases, but not all, sales volumes of cement fell. Notably, both Holcim and Heidelberg Materials did not appear to release these figures. Heidelberg Materials did say though that its sales volumes declined in all business lines as “a result of the global economic down-turn.” In Holcim’s case, on top of whatever else has been going on over the last six months, the group has continued to divest cement assets as it realigns its portfolio. One more interesting point to note is that, instead, Holcim and Heidelberg Materials highlighted their reductions in CO₂ emissions at the start of their half-year reports.

Holcim continued to expand its light building materials business segment in North America as well as picking up some aggregate and ready-mix concrete assets in North America and Europe. Its sales grew fastest in North America, although Europe generated more sales overall. Elsewhere the other geographic business areas all held up. The group’s Solutions & Products division, the one responsible for the light building materials, lost sales and earnings year-on-year. This was blamed on the “normalisation of buying patterns” in the roofing market in North America in late 2022 and carrying into 2023, leading to destocking in various distribution channels. How this might effect the group’s ongoing diversification strategy remains to be seen.

Heidelberg Materials was more upfront about the specifics of its cement business in the first half of 2023. Sales volumes fell in all business lines. For cement, the largest falls were reported in the Western and Southern Europe Group area due to a ‘significant’ decline in residential construction followed by the Africa-Eastern Mediterranean Basin area although a slight increase was recorded in deliveries in Asia-Pacific. That last region benefited from the local subsidiary increasing its cement and clinker deliveries in Indonesia. This was reportedly due to the company leasing the Maros cement plant in September 2022. The plant serves markets in the east of the country. Overall, despite the falls in revenue in many regions, the group pushed up its prices sufficiently to keep net sales revenue and earnings growing well.

Cemex, meanwhile, was keen to shout about its improved earnings in all of its regions. It attributed this to its price strategy, lowering input cost inflation and the growing effects of its investments portfolio and its Urbanisation Solutions business. Each of the group’s main regions – Mexico, the US and Europe – performed well, with Mexico growing sales the fastest, the US driving up earnings the most and Europe, Middle East, Africa and Asia holding growth steady despite demand issues. Pricing was cited as a main issue for the success of each region.

Vicat’s sales and earnings rose due to increased sales volumes of cement and higher prices. At home in France, the company successfully fought off falling cement sales volumes with price rises, particularly due to energy price inflation. North America, the group’s other big market, grew strongly, boosted by the ramp-up of production and sales from the new kiln at the Ragland plant in Alabama. Finally, Titan experienced a similar situation to the other companies featured here, with increasing demand driving sales and further helped by prices. Earnings then grew in turn. Unlike the other companies, the US contributed a much larger share of sales for Titan than Europe or elsewhere. Back home in Greece the company’s sales and earnings benefited from increased sales volumes across all business lines. Both Vicat and Titan had mixed experiences in Egypt and Türkiye, with negative currency exchange effects causing problems in both countries, despite demand mounting in the latter.

On the basis of these financial results, it has been a positive first half for the larger cement companies based in Europe and North America. Cement sales volume growth has been mixed, where known, but price rises have compensated for this, leading to higher earnings. Whether these companies can continue to pull off this trick as or if global inflation starts to slow down is very much an ongoing question. As mentioned at the start, some of the companies also led their half-year reports with emission figures and many of them prominently highlighted forthcoming sustainability projects. These companies may be making most of their money in Europe and North America but there is clearly an awareness that these regions are also leading globally in implementing CO₂ emission legislation.

Canada/UK: Carbon Upcycling has raised US$26m in a Series A funding round. The clean tech company says that the funding will support its construction of planned carbon capture systems at CRH's Mississauga cement plant in Canada and Cemex UK's Rugby cement plant in the UK. Carbon Upcycling’s technology injects captured CO₂ into industrial byproducts and minerals to produce supplementary cementitious materials. BDC Capital and Climate Investment led the funding round, with strategic investments from Cemex Ventures, CRH and Oxy Low Carbon Ventures.

Carbon Upcycling chief executive officer Apoorv Sinha said "Closing this round is a major milestone on the road to becoming the most impactful carbon tech company of this decade.” He continued “Over the next year, our mission is to demonstrate our technology's versatility, scalability and operational elegance. Significant, cost-effective decarbonisation potential in the cement industry is possible without a green premium.”

Mexico-based Cemex first invested in Carbon Upcycling via its venture capital unit Cemex Ventures in February 2022. Its said “Cemex is committed to supporting decarbonisation for the built environment, and our follow-on investment in Carbon Upcycling demonstrates such ambition. Carbon Upcycling provides a scalable solution that effectively reduces the carbon footprint of cement. Increasing the supply and use of cementitious materials aligns with Cemex’s goals of reducing CO₂ emissions and becoming fully net-zero by 2050”

The collaboration between Carbon Upcycling and Cemex dates to early 2020, and work towards a commercial-scale plant at the Rugby cement plant commenced in June 2022. The project will target a capture capacity of 1600t/yr, and has secured US$2.96m in government funding from UK Research and Innovation. Cemex says that it will subsequently roll out further CO₂ mitigation projects in partnership with Carbon Upcycling at cement plants across Europe, the Middle East and Africa, Mexico and the US.

Mexico: Cemex recorded first-half 2023 revenues of US$8.6bn, up by 11% year-on-year from US$7.76bn for the first half of 2022. The group's operating earnings before interest, taxation, depreciation and amortisation (EBITDA) totalled US$1.69bn, up by 18% from US$1.4bn. The group said that the results bring it close to achieving its aim of restoring its 2021 EBITDA margins.

Chief executive officer Fernando A González said “The success of our pricing strategy, bolt-on investments and Urbanisation Solutions business, as well as decelerating cost inflation, are driving what is shaping up to be a very strong year for our company." He continued "Beyond our financial results, we continue progressing on the ambitious carbon reduction and circularity commitments of our Future in Action programme, remaining on the path to becoming a net zero CO2 company by 2050.”

US: Cemex USA has commissioned a new 225t cement unloader for handling dry bulk materials from ships at the Port of Palm Beach in Florida. The port says that the producer invested US$7m in the equipment. It is decorated with a mural of a manatee cow and calf, dedicated to local conservation charity Friends of Manatee Lagoon.

Cemex highlighted its Clyngas project at its Alicante cement plant in Spain this week. The project will produce synthesis gas (syngas) from different types of waste for direct injection into the burner at the plant during the combustion process. It is being run in conjunction with Waste to Energy Advanced Solutions (WTEnergy), a company that Cemex invested in at the end of 2022. It is also receiving Euro4.4m in funding from the European Commission (EC) as part of its innovation fund for small scale projects. The initiative estimates that it will save over 400,000t of equivalent CO₂ during the first 10 years of the project's life by replacing petroleum coke with syngas.

Clyngas is another example of Cemex’s innovation with alternative fuels for cement and lime. It follows on from the group’s work with hydrogen injection into cement kilns. As presented at the 15th Global CemFuels Conference 2022 it has been using hydrogen in low volumes as a combustion enhancer in more than 20 plants worldwide. However, it was also looking into using hydrogen more directly as a fuel and as a feedstock for other alternative fuels. WTEnergy’s gasification process could potentially link up to this as it converts waste streams such as wood chips, agricultural waste, refuse derived fuel (RDF), solid recovered fuel (SRF), dry sewage sludge, meat and bone meal, poultry litter and plastics into syngas. WTEnergy then proposes that its gasification process and/or the syngas can be used for power generation and thermal applications. In the case of the Clyngas project it will be the latter, as the gasification process will be used to boost the burnability characteristics of RDF with a high biomass content. One part of this to note is that the syngas can potentially be used to manufacture hydrogen. This would be a useful capability for a cement company, for example, that was already using alternative fuels and was now considering further decarbonisation by switching to using hydrogen.

A few other cement companies have been looking at synthetic fuels too, but this has generally been as a by-product of carbon capture and utilisation. This week Lafarge France, for example, said it had signed a memorandum of understanding with Axens, EDF and IFP Energies Nouvelles for a synthetic fuel production trial. Its plan is to build a unit that will produce synthetic kerosene using captured CO₂ from a carbon capture installation at Lafarge France's Saint-Pierre-La-Cour cement plant. The kerosene will then be sold to airlines. Other examples of cement companies looking at using captured CO₂ to manufacture synthetic fuels include Finnsementti’s pre-engineering study with Aker Carbon Capture to consider producing methanol as a fuel for transport, Holcim’s and TotalEnergies’ various plans of what to do with the CO₂ captured from the-to-be upgraded Obourg cement plant and Cemex Deutschland’s ambitions for its Rüdersdorf plant.

As can be seen above there are different types of synthetic fuels and cement companies are at the research and pilot stages. Although there isn’t a commonly accepted definition of what a synthetic fuel is, the general meaning is that of a fuel made from feedstock using a chemical reaction as opposed to, say, a refining process. The wide variety of potential synthetic fuels puts the confusion over the different types of hydrogen into perspective. However, this may be a problem for a later date if usage by cement companies becomes more serious.

What is a problem, though, has been the EC’s planned legislation to phase out the use of industrial CO₂ in synthetic fuels by 2041. Cembureau, the European cement industry association, warned in late 2022 of the issues this would pose for industries trying to find a way to utilise their CO₂ emissions where storage was too difficult or expensive. Its view was that while synthetic fuels using industrial CO₂ are not fully net-zero, as the captured CO₂ is later released into the atmosphere, it is a necessary short to medium term step for sectors trying to make the transition. Companies trying to build industrial-scale chemical plants for synthetic fuels need running periods of 20 to 30 years to achieve payback. As of March 2023 Cembureau was still concerned about the implication of proposed regulations, specifically with regards to the proposed criteria for which synthetic fuels could be used, based on their greenhouse gas emissions savings (at least 70% compared to the regular fuels being replaced). It directly linked this to synthetic fuels projects being launched by the cement sector that might be adversely affected by the new rules. The EC published the legislation in late June 2023 and it is set to become legal in mid-July 2023.

Using synthetic fuels either as a fuel or a by-product from cement production is an area of interest currently with the projects detailed above and others in progress. One vision for their use in Europe, at least, is that they might offer a route for carbon capture for cement plants without access to the logistic networks necessary for sequestration. Whether they find a place in cement manufacture either on a transitional basis or over a longer term should become clearer over the coming decade. Yet the EC’s new rules are likely to slow this process down as at least some of the planned pilots may become unviable in Europe. Other jurisdictions around the world take note.

Spain: Cemex España has secured Euro4.4m in EU funding for an upgrade to its Alicante cement plant in Valencia. The project will launch the use of Clyngas synthetic gas as alternative fuel (AF) at the plant. Thermochemical conversion specialist WtEnergy, a subsidiary of Cemex Ventures, will supply the syngas. The partners say that this upgrade will reduce CO₂ emissions by 400,000t per decade.

Parent company Cemex said "This project is part of Cemex’s Future in Action programme, which seeks to achieve sustainable excellence through climate action, circularity and natural resource management, with the primary objective of becoming a net-zero CO₂ company."

Colombia: Cemex says that its Santa Rosa cement grinding plant is the first unit in its South, Central America and the Caribbean (SCAC) region to attain water self-sufficiency. The plant independently meets its water requirements using a 9000m³ reservoir, constantly replenished thanks to rainwater, runoff, and water circulation devices. The move aligns with the company's Water Management Roadmap, part of its Future in Action program. The achievement takes Cemex closer to its 2030 target of reducing freshwater consumption in its cement operations by 20%.

UK: Cemex UK has completed upgrades of its Dove Holes, Selby and Bletchley depots in partnership with MLP Railway Maintenance. As a result of the upgrade, the Selby depot in North Yorkshire can now receive an increased number of wagons per train, and complete turnarounds more quickly. Meanwhile, the producer relayed two reception lines at the Dove Holes depot in Derbyshire and installed new walkways, CCTV and a waterproof display screen for offloading at the Bletchley depot in Buckinghamshire.

Cemex UK’s rail and sea manager Mark Grimshaw-Smith said “It’s important that we continue to invest in our railheads across the UK. This not only ensures that the safety and wellbeing of those who work on our sites is enhanced on an ongoing basis, but it also provides further resilience in the operation, transporting more materials by train and thus taking more trucks off the road.”

Peru: Invercem has successfully commissioned its new 220,000t/yr Pisco grinding plant in Ica Department. Management News has reported that the plant cost US$30m to build. Cemex Peru will supply clinker for use in cement production at the plant. Invercem plans to supply cement produced at the plant to the Cusco market under the Patrón brand. The company says that the facility has the potential to further expand up to a capacity of 330,000t/yr. In the longer term, Invercem aims to establish an integrated cement plant and limestone mine.

Spain: Cemex España and ecology company Cinclus have extended their quarry rehabilitation partnership to a national level. Under the extended collaboration, the partners will implement restoration plans for all of Cemex España’s quarries, in line with the cement producer’s Biodiversity Action Plans.
