Cemex publishes 2021 Integrated Report
28 March 2022Mexico: Cemex has published its 2021 Integrated Report. Under the report’s Climate Action section, Cemex recorded a 4.7% year-on-year decrease in its CO2 emissions per tonne of cementitious material. Alternative fuel (AF) substitution rose to 29%, while its products’ average clinker factor fell to 75%. It was the first company to complete a global roll-out of its reduced-CO2 cement and concrete range (Vertua). It established Science-Based Targets Initiative (SBTi)-verified well below 2°C 2030 climate action goals and joined the UN’s Race to Zero and the Business Ambition for 1.5°C coalition. It also became a founding member of the World Economic Forum’s First Movers Coalition for zero-carbon economic development.
The year also brought major Sustainability and Circular Economy milestones, including managing 57 times the volume of waste it sent to landfill, positively impacting 25m lives through its Social Impact Strategy and processing 61% of global sales through its Cemex Go digital sales platform. For the second consecutive year, its Net Promotor Score was 68, ‘substantially above’ the construction and engineering industry average.
Poland: The Building Research Institute has issued environmental product declarations (EPDs) for all six cement types produced at its Chełm and Rudniki cement plants and Gdynia grinding plant. The products in question were two CEM I cements, two CEM II Portland fly ash cements, another CEM II cement and a CEM III slag cement. Cemex Poland additionally obtained EPD certification for its Vertua Classic and Vertua Plus concrete products.
Materials director Michał Grys said “For us, product certification is another important step towards sustainable construction and a sustainable future. EPD declarations provide our clients with additional confirmation of the properties of products offered by Cemex Poland. They also improve their chances of obtaining LEED or BREEAM certificates for their investments.”
From the Nordics to the Mediterranean, European countries lead the field in reduced-clinker cement production using supplementary cementitious materials (SCMs). While consumers, faced with ever-greater choice, continue to opt for sustainability, projects to improve existing SCMs and develop new ones have won government backing and have become a matter of serious investment for other heavy industries beside cement. European cement producers’ decisions are steering the course to a world beyond CEM I. Yet, even in Europe, great untapped potential remains.
Companies generated a good deal of marketing buzz around their latest reduced-CO2 cement ranges in 2021 and the first quarter of 2022: Buzzi Unicem’s CGreen in Germany and Italy, Holcim’s EcoPlanet in six markets from Romania to Spain, Cementir Holding’s Futurecem in Denmark and Benelux, and Cemex’s Vertua in Spain and several other countries. All boast reduced clinker factors through the use of alternative raw materials. This, however, is really a rebranding of a long-established norm in Europe.
Since 2010, cements other than CEM I have constituted over 75% of average annual cement deliveries across Cembureau member countries (all cement-producing EU member states, plus Norway, Serbia, Switzerland, Turkey, the UK and Ukraine). This statistic breaks down differently from country to country. CEM II is the norm in Austria, Finland, Portugal and Switzerland, with deliveries in the region of 90%. Portland limestone cement (PLC) makes up a majority of deliveries in all four. It has been central to Switzerland’s transition to 89% (3.72Mt) of CEM II deliveries out of a total 4.18Mt of cement despatched in 2021. There, the main types of cement were CEM II/B-M (T-LL) Portland composite cement, with 1.38Mt (33%), and two different classifications of PLC: CEM II/A-LL PLC, with 1.28Mt (31%), and CEM II/B-LL PLC, with 888,000t (21%).
A second approach is that of the Netherlands, where CEM III blast furnace slag cement with a clinker factor below 65% predominates, favoured for its sulphate resistance and the protection it offers against chloride-initiated corrosion of steel reinforcement in marine settings. By contrast, the UK has traditionally maintained a higher reliance on CEM I cement. This can be partly explained by the preference of builders there for adding fly ash or ground granulated blast furnace slag (GGBFS) at the mixing stage. Nonetheless, CEM II Portland fly ash cement held a 14% (1.43Mt) market share in the UK’s 10.2Mt of cement consumption in 2021.
The UK Mineral Products Association (MPA) has identified limestone as an underutilised resource in the country’s cement production. Together with HeidelbergCement subsidiary Hanson Cement, it has applied for a change to National Application standards to allow the production of Portland composite cement from fly ash and limestone or GGBFS and limestone. The association has forecast that Portland composite cement could easily rise to 30 – 40% of UK cement consumption, and that this has the potential to eliminate 8% of the sector’s 7.8Mt/yr-worth of CO2 emissions.
Metallurgical waste streams have long flowed into European cement production, primarily as GGBFS, but also as bauxite residue. In 2021, alumina production in the EU alone generated 7Mt of bauxite residue, of which the bloc recycled just 100,000t (1.4%) that year. Two projects – the Holcim Innovation Center-led ReActiv project and Titan Cement and others’ REDMUD project – aim to produce new alternative cementitious materials from bauxite residue.
By collaborating with other industries, cement producers’ investments can most effectively reduce the overall cost of using these materials in cement production. In Germany, HeidelbergCement and ThyssenKrupp’s Save CO2 project aims to develop new improved latent hydraulic binders or alternative pozzolan from GGBFS by producing slag from directly reduced iron (DRI). The Save CO2 team believes that GGBFS substitution for clinker has the capacity to eliminite 200Mt/yr of CO2 emissions from global cement production.
Meanwhile in the world of mining, ThyssenKrupp and others’ NEMO project is investigating the recovery of a useable mineral fraction for cement production from the extractive waste of the Luikonlahti and Sotkamo mines in Finland and the Tara mine in Ireland, through bioleaching and cleaned mineral residue upcycling. This may give cement producers full access to Europe’s 28Bnt stockpiles of sulphidic mining waste, of which mines generate an additional 600Mt each year.
Denmark-based CemGreen, which produces the calcined clay supplementary cementitious material CemShale, is developing a shale granule heat-treating technology called CemTower. This consists of three pieces of equipment vertically integrated into cement plants’ preheaters, kilns and coolers, and brings the processing of waste materials – here oil shale – to the cement plant.
Lastly, cement producers are exploring the possible uses of waste made of cement itself. In Wallonia, HeidelbergCement subsidiary CBR’s CosmoCem project is investigating the production of alternative cement additives from large available flows of local demolition, soil remediation and industrial waste. Similarly, the Greece-based C2inCO2 project seeks to mineralise fines from concrete recycling for HeidelbergCement to use in the production of novel cements in its Greek operations.
In Switzerland, ZND Portland composite cement (produced using fine mixed granulate from building demolitions) is the third largest cement type, with 178,000t (4.3%) of total deliveries – narrowly behind CEM I with 239,000t (5.7%).Holcim Schweiz developed its Susteno 4 ZND Portland composite cement with Switzerland’s lack of any ash or slag supply in mind, demonstrating the potential flexibility of a circular economic approach to cement production.
On 21 March 2022, the University of Trier reported that it is in the process of mapping mineral resources, waste deposits and usable residues ‘on a cross-border scale,’ in an effort to produce new materials for use in cement production. Industry participants include France-based Vicat, CBR, Buzzi Unicem subsidiary Cimalux and CRH subsidiary Eqiom. Vicat is preparing a kiln at its 1Mt/yr Xeuilley cement plant in Meurthe-et-Moselle to use in testing new alternative raw materials developed under the project.
For Cembureau and its members, work continues, with the goal of Net Zero by 2050 constantly in sight. This goal includes a reduction in members’ clinker-to-cement ratios to well below 65%. In this, the association and its members are working towards a world not just beyond CEM I, but beyond CEM II, too. What exactly this will mean remains to be seen.

Cemex to restart CPN cement plant’s Line 2
08 March 2022Mexico: Cemex says that it plans to restart Line 2 at its CPN cement plant in Sonora State. The line has a capacity of 0.8Mt/yr. Cemex will invest US$29m in restarting it, bringing its total recent investments in the CPN plant to US$44m. It previously invested US$15m in a restart of the plant’s 1Mt/yr Line 1 in 2021. When operational in mid-late 2022, Line 2 will join the existing line in supplying cement to Arizona, California and Nevada in the US.
Cemex USA president Jaime Muguiro said “Many cement customers in the western US have been impacted by tight supply constraints for several months, and at Cemex, we are proactively looking for opportunities to further alleviate those conditions and enrich customer experiences by enhancing how we operate while utilising our global reach.” He continued “Customers require more cement to keep pace with the region’s growth, and we want to ensure they have stable and steady access to the high-quality materials that are essential to meet their needs.”
Cemex commissions Line 2 at Tapeaca cement plant
08 March 2022Mexico: Cemex has successfully commissioned its new Line 2 at its Tapeaca, Puebla, cement plant.
Cemex’s Mexico regional vice president operations and technology Ernesto Felix said that the work ‘brought together a great team’ of Cemex colleagues.
Cemex Ventures invests in PartRunner

The startup operates a fleet of trucks which provide flexible service to warehouses, retailers and job sites across the US. Under Cemex Ventures’ guidance, it plans to expand its services to also cover Mexico.
Cemex Ventures director Gonzalo Galindo said "This solution fits perfectly with Cemex's commitment to offer our customers greater control over their businesses by improving efficiency and transparency in the delivery of construction products and materials.”
2021 roundup for the cement multinationals
02 March 2022Cement markets have mostly recovered following the shock emergence of coronavirus in 2020. Most of the producers that have released their results so far for 2021 have reported strong boosts to sales revenue and racing earnings as something more like normality resumed. The following roundup covers a selective group of cement companies around the world.
The recovery in 2021 has made the outliers in the companies covered here noteworthy. UltraTech Cement, Semen Indonesia and Dangote Cement are all large regional companies with dominant positions domestically and varying degrees of international spread. As can be seen in Graph 1, UltraTech Cement and Dangote Cement both reported very large increases in sales, over 20% year-on-year. By contrast, Semen Indonesia sales fell very slightly.

One reason for UltraTech Cement and Dangote Cement’s success can be seen in Graph 2 (below). Both companies managed to sell more cement in 2021. Semen Indonesia did not due to Indonesia’s production overcapacity and new competitors. It also blamed a significant rises in coal prices for a 9% drop in its earnings before interest, taxation, depreciation and amortisation (EBITDA).
UltraTech Cement has been wary of successive waves of coronavirus throughout its 2022 financial year, but generally the Indian regional markets have recovered and government-backed rural housing and infrastructure spending have supported growth. It did note rising coal prices earlier in the year, but these were reported to have somewhat softened during the quarter to 31 December 2021. It is worth noting that the ongoing war in Ukraine is affecting energy markets but more on this at the end of this article. Dangote Cement’s performance was slowed somewhat by the start of coronavirus but it has since resumed its turbo-charged trajectory with volumes, revenue and earnings growth all above 10% in 2021. Mostly this performance is supported by the Nigerian market but the company is doing well internationally too.

Holcim and HeidelbergCement’s increase in sales revenue in 2021 are actually fairly similar on a like-for-like basis, both with around 10%. The former’s sales volumes were up across cement, ready-mixed concrete and aggregates in each of its regions around the world, as were sales revenue. Holcim’s big move in 2021 has been the expansion of its Solutions & Products segment with the acquisition of Firestone in April 2021. Now this has continued with the completion of the Malarkey Roofing Products purchase on 1 March 2022, a few days after it released its 2021 results. Chief executive officer Jan Jenisch described the move towards lightweight building materials as generating, “further double-digit growth engines for the company.” As an aside, it was fascinating to see CRH leave the building envelope business this week, mostly based in the US, with an agreement to sell up its division for US$3.8bn to private equity. The business CRH is divesting sells architectural glass, storefront systems, architectural glazing systems and related hardware to customers primarily in North America. CRH is clearly pursuing a different business strategy to Holcim.
HeidelbergCement has also reported a strong year in 2021 albeit without the Holcim razzle-dazzle of barging into new market areas. It noted significant increases in energy prices and pandemic‐related lockdowns in some key markets in Asia. It described a very slight cement sales volume decline in Africa and the Middle East and a drop in earnings in Asia. Its trump cards are its carbon capture projects coming down the pipeline. It’s keen to remind investors about this with the unspoken implication that it might save the company money in the future when carbon taxes bite further.
Both Cemex and Buzzi Unicem followed the growth pattern seen in sales and earnings by the other larger multinational producers covered above. Central and South American markets really took off for Cemex in 2021, starting with its home market in Mexico. However, growth was present, although slower, in both its largest markets in the US and its Europe, Middle East, Africa and Asia region. Notably cement volumes in the Philippines grew by 7% and that’s even with the devastation caused by typhoons at the end of the year taken into account. Similarly, Buzzi Unicem performed well in 2021 due to growth in Italy, the US and Eastern Europe compensating for a small sales decline in Germany. As mentioned in Update on Ukraine, February 2022 Buzzi Unicem has particular exposure to the war in Ukraine as it operates two cement plants in Ukraine and two units in Russia but this is a problem for the 2022 financial year.
To finish on Ukraine, first and foremost, a human tragedy is unfolding. Yet the war also presents many economic challenges to financial markets through sanctions and counter-actions. A recession in Russia looks likely as do energy price surges in the US and Europe leading to further inflation and, perhaps, recessions too. All this potentially lies ahead. For now, the dilemma for US and European-based cement companies and suppliers with operations in Russia is reputational. Should they continue to do business in Russia as public opinion hardens and companies like BP, Shell, Equinor, HSBC and AerCap head for the exit? The Russian government has blocked foreign companies and individuals from selling shares locally but pressure looks set to intensify for such companies to do something.
Belgium: Cemex has joined the Cambridge Institute for Sustainability Leadership (CISL)’s Corporate Leaders Group Europe in order to lead the corporate transition to a climate neutral economy. The company joins a cross-sectoral body of members from across the EU.
Cemex’s Europe, Middle East and Africa regional president Sergio Menendez said “With its Future in Action programme, Cemex is committed to leading on the road to carbon neutrality. We are proud to join forces with the CISL’s Corporate Leaders Group Europe and other global companies to accelerate the decarbonisation of the built environment. We look forward to working together with the Corporate Leaders Group Europe to help us all achieve our shared climate action goals in Europe.”
Cemex USA commences sale of Portland limestone cement from Brooksville and Demopolis cement plants
28 February 2022US: Cemex USA has begun selling Portland limestone cement produced at its Brooksville, Florida, and Demopolis, Alabama, plants across the Southeastern US. The producer says that the cement retains the durability of ordinary Portland cement or is more durable while reducing CO2 emissions by 10%. Cemex USA aims to increase its PLC production at the plants, and possibly to begin producing it at other US cement plants, in early 2022.
President Jaime Muguiro said "At Cemex, we acknowledge that climate action is one of the most important issues facing our world, and we are committed to being part of the solution. Our company has ambitious emission-reduction targets, and by offering lower carbon products that deliver brilliant performance like PLC, we can continue to work toward those goals while encouraging customers to join us in the journey."
Cemex’s production costs rise due to new mining tax in Nuevo León
23 February 2022Mexico: The Mexican Chamber of the Construction Industry (CMIC) has voiced cement price concerns following the introduction of a new environmental tax on mining activity in the state of Nuevo León. Cemex operates a quarry in the state, and has resultingly experienced a rise in the cost of its cement production. The El Norte newspaper has reported that the producer’s Monterrey, Nuevo León, cement plant supplies cement across northeastern Mexico.
CMIC also lobbied the government to begin awarding public works contracts to private investors instead of the Mexican armed forces. It argued that this would help to generate jobs.
