Delegates at the Global CemCCUS Conference last week applauded when Anders Petersen, the Senior Project Manager Brevik CCS, Heidelberg Materials said that the Brevik cement plant will be capturing CO₂ and permanently storing it within the year. Rightly so. This moment will mark a historic milestone for the sector when it arrives. Net zero cement production is coming.

Last week’s event in Oslo delivered an overview of the current state of carbon capture in the cement and lime industries. It explored the practical challenges these industries face in capturing CO₂ emissions and - crucially – then working out what to do with them afterwards. Incredibly, delegates were able to view the construction site of Heidelberg Materials’ forthcoming full-scale carbon capture unit at its Brevik plant in Norway. On the same day as the tour, Holcim broke ground on the Go4Zero carbon capture project at its Obourg plant in Belgium.

The key takeaway at the conference was that a (dusty) bulk solids sector is starting to work with handling (clean) gases in a way it hasn’t before. This recurred repeatedly throughout the conference. Petersen summarised it well when he described Brevik as a meeting pointing between the cement industry and the petrochemical one. It looks likely at present that there will not be a single predominant carbon capture technology that the majority of cement plants will deploy in the future. Similarly, CO₂ storage infrastructure and sequestration sites differ. Utilisation plans are less developed but also offer various options. Yet, if carbon capture becomes common at cement and lime plants, then these companies will need to learn how to filter and handle gases regardless of the capture method and destination for the CO₂. So presentations on filtration and compressors were a revelation at CemCCUS.

The key obstacle remains how to pay for it all. By necessity, most of the big early projects have received external funding, mostly from governments. Although, to be fair, the private companies involved are often investing considerable amounts of their own money and taking risks in the process too. In the European Union (EU) CO₂ is being priced via the Emissions Trading Scheme and investments are being made via the EU Innovation Fund and other schemes. In the US the approach lies in tax breaks, on-shoring and investment in new sustainable technologies.

However, other countries have different priorities. Or as a South Asian contact told Global Cement Weekly at a different conference, “How can our government think about sustainability when it can’t feed everyone?” The world’s biggest cement producing countries are China and India, and then the EU and the US follow. Brazil, Türkiye and Vietnam are at similar levels or not far behind. The EU and the US represent about 9% of global cement production based on Cembureau figures for 2022. China and India cover 61% of production. Neither of these countries has announced a plan to encourage the widespread construction of carbon capture units. Once China ‘gets’ cement carbon capture though, it seems plausible that it will dominate it as it has in many other sectors such as solar panel production. Exporters such as Türkiye and Vietnam will have to adapt to the rules of their target markets.

The march by the cement and lime sectors towards carbon capture has been long, difficult and expensive. It also has a long, long way to go. Yet, the next decade promises to be exciting as new technologies are developed and tested, full-scale projects are commissioned and CO₂ pipelines, sequestration sites and usage hubs come online. The next key milestones to look out for include the first full-scale installations using other capture methods (such as oxy-fuel kilns), the first CO₂ pipeline network that hooks up to a cement plant, the first land-based sequestration site, the first industrial hub that uses CO₂ at scale to manufacture a product, new government policies in China and India, and the first large unit that is funded entirely from private finance. To end on a positive note, a Cembureau representative at the Global CemCCUS Conference reckoned that Europe will be able to capture 12Mt/yr of CO₂ by 2030. If it happens, this will be a major achievement and a serious statement of intent towards net zero for the sector.

This short recap of the event barely touches the surface of what happened so be sure to read the full review of the 1st Global CemCCUS Conference.

The 2nd Global CemCCUS Conference will take place in Hamburg in May 2025

Indonesia: The Jakarta administration has commenced the construction of the Rorotan refuse derived fuel (RDF) plant on a 7.8-hectare site in North Jakarta, aiming to process 2,500t/day of waste. The US$75m project is funded from the 2024 regional budget and is expected to be completed by December 2024 and start operations in early 2025. The city of Jakarta produces nearly 8,000t/day of waste, the majority of which goes to the Bantar Gebang landfill in West Java. The facility will convert 35-40% of the waste processed into about 875t/day of alternative fuels.

The Rorotan facility is the second RDF plant initiated by the Jakarta administration, following the Bantar Gebang facility, which began operations in 2023. This new facility marks a shift from the planned waste-to-energy incinerator in Sunter, which was cancelled due to high costs and bureaucratic delays.

Acting Jakarta governor Heru Budi Hartono said "This technology is still a very small part of our larger efforts to address the city's waste problem."

Head of the Jakarta Environment Agency Asep Kuswanto said "The RDF can become another source of revenue for the city, as we can sell the alternative fuel from the facility to industry."

Zambia: Grizzly Mining has announced an investment of US$200m to establish a cement plant in Solwezi, Northwestern Province. The announcement was made by the company’s vice chairperson Abdoul Ba during an interview, according to the Times of Zambia.

Belgium: Holcim kicked-off its Go4Zero project at its Obourg plant on 16 May 2024 in an event attended by the Belgian Prime Minister Alexander De Croo and the European Commissioner for Climate Action Wopke Hoekstra. The €500m Go4Zero project, supported with €230m of funding from the European Union, will enable the integrated plant to reduce its CO₂ emissions by 30% by 2027 and to produce 2Mt/yr of CO2-free cement by 2029. When fully operational, the Obourg plant will capture 1.2Mt/yr of CO₂.

The Go4Zero project incorporates a number of approaches to achieve net-zero CO₂ cement. The centrepiece is an oxy-fuel combustion process to generate an easy-to-handle exhaust gas with up to 80% CO₂. This will be coupled to a cryogenic purification unit to generate a >99%-pure CO₂ stream .The project will also make use of waste heat recovery (WHR), new exhaust filtration equipment and Europe’s largest floating solar panel farm.

Tunisia: Les Ciments de Bizerte has announced that it experienced financial difficulties during the first quarter of 2024. The company was unable to import petcoke due to a lack of cash and looming loan repayments, leading to the total suspension of clinker production. This left the company only able to grind existing clinker and operate its quay. As a result, the company’s total sales in the first quarter of 2024 fell by 53% year-on-year compared to the same period in 2023, falling from US$8.3m to US$3.9m.

Before Russia invaded mainland Ukraine on 24 February 2023, many predicted that full-scale conflict would be averted. When the attack began, Russian President Vladimir Putin himself expected a 10-day war, according to think tank RUSI. 15 May 2024 marks two years, two months and three weeks of fighting, with no end in sight.

Ukrcement, the Ukrainian cement association, recently published its cement market data for 2023, the first full year of the war. The data showed domestic cement consumption of 5.4Mt, up by 17% year-on-year from 4.6Mt in 2022, but down by 49% from pre-war levels of 10.6Mt in 2021. In 2023, Ukraine’s 14.8Mt/yr production capacity was 2.7 times greater than its consumption, compared to 1.4 times in 2021. Of Ukraine’s nine cement plants, one (the 1.8Mt/yr Amwrossijiwka plant in Donetsk Oblast) now lies behind Russian lines. Four others sit within 300km of the front line in Eastern and Southern Ukraine. Among these, the 4.4Mt/yr Balakliia plant in Kharkiv Oblast, the largest in the country, first fell to the Russians, but was subsequently liberated in September 2022.

Before the war, Ukrcement’s members held a 95% share in the local cement market. Their only competitors were Turkish cement exporters across the Black Sea, after the Ukrainian Interdepartmental Commission on International Trade successfully implemented anti-dumping duties against cement from Moldova and now-sanctioned Belarus and Russia in 2019. Since then, Turkish cement has also become subject to tariffs of 33 – 51% upon entry into Ukraine, until September 2026. The relative shortfall in consumption has led Ukraine’s cement producers to lean on their own export markets. They increased their exports by 33% year-on-year to 1.24Mt in 2023, 330,000t (27%) of it to neighbouring Poland.

Russia’s invasion has made 3.5m Ukrainians homeless and put the homes of 2.4m more in need of repair. In a report published in Ukrainian, the US Agency for International Development (USAID) set out its three-year rebuilding plan for the country. USAID projects an investment cost of €451bn, with the ‘main task’ besides homebuilding being to increase the share of industrial production in the economy. Ukraine is 90% equipped to produce all building materials required under the plan. Their production, in turn, will create or maintain 100,000 jobs and US$6.5bn in tax revenues. Reconstruction will also involve the Ukrainian cement industry returning to close to full capacity utilisation, producing 15 – 16Mt/yr of cement.

CRH, an established local player of 25 years, looks best set to claim a share of the proceeds. Stepping down an order of magnitude from billions to millions, Global Cement recently reported CRH’s total investments in Ukraine to date as €465m. Since war broke out, the company has more than tripled its rate of investment, to €74.5m. The Ireland-based group is in the protracted administrative process of acquiring the Ukrainian business of Italy-based Buzzi. If successful, the deal will raise its Ukrainian capacity by 56%, to 8.4Mt/yr – 57% of national capacity. This unusual clumping of ownership may be made possible by the participation of European Bank for Reconstruction and Development in partly acquiring the assets, as per a mandate letter signed with CRH in 2023.

Leading Ukrainian cement buyer Kovalska Industrial-Construction Group bemoaned the anticipated increase in market concentration. On the one hand, this sounds like a classic tiff between cement producers and users with shallow pockets. On the other hand, an antebellum allegation of cement industry cartelisation should give us pause for thought. Non-governmental organisation The Antitrust League previously reported Ukraine’s four cement producers to the government’s Anti-Monopoly Committee for alleged anticompetitive behavior. This was in September 2021, when Ukraine was barely out of lockdown, let alone up in arms. With all that has happened since, it may seem almost ancient history, yet the players are the same, CRH and Buzzi among them.

Ukrcement and its members have secured favourable protections from the Trade Commission, and, for whatever reasons, evaded the inconvenience of investigation by the Anti-Monopoly Committee – a state of affairs over which the Antitrust League called the committee ‘very weak.’ The league says that producers previously raised prices by 35 – 50% in the three years up to 2021. In planning a fair and equitable reconstruction, Ukrainians might reasonably seek assurance that this will not happen again.

All these discussions are subject to a time-based uncertainty: the end of the war in Ukraine. A second question is where the finances might come from. The EU approved funding for €17bn in grants and €33bn in loans for Ukraine on 14 May 2024. Meanwhile, countries including the UK have enacted legislation to ensure Russia settles the cost of the conflict at war’s end. If Ukraine achieves its military aims, then the finances may flow from the same direction as did the armaments that demolished Ukrainian infrastructure in the first place.

The first piece of Ukraine annexed by Russia was Crimea in February 2014, making the invasion over a decade old. Against such a weight of tragedy, the country cannot lose sight of the coming restoration work, and of the need to ensure that it best serve Ukrainians.

India: JSW Cement will establish its first cement plant in the north of the country at Nagaur, Rajasthan. The new site will begin with a capacity of 3.3Mt/yr, eventually expanding to a capacity of 15Mt/yr by 2026.

Managing director Parth Jindal posted on X "Extremely proud that JSW Cement is entering North India, today we have broken ground at our site in Nagaur, Rajasthan. A new beginning for JSW, one that will see us becoming a pan-Indian cement player by 2026.”

Kenya-based East African Portland Cement (EAPCC) made the news this week with the reopening of the company’s Athi River cement plant after a month-long shutdown. The closure was conspicuous because the company is gradually working towards increasing the integrated plant’s production capacity. The first phase of the maintenance and upgrade project saw the replacement of the production line’s kiln shell in September 2022. The current aim is to increase the unit’s cement production capacity to 1Mt/yr by mid-2026. The recent shutdown appears to have been a more normal annual renewal and repair job but EAPCC has used it as a promotional opportunity. Notably, a spokesperson for EAPCC described clinker as the “new gold” in a recent video explaining what was going on.

It’s an improvement on the financial trouble EAPC found itself stuck within in the late 2010s before the government ended up taking a controlling share in the cement producer. On this front local media reported in July 2023 that the government had found a 'strategic investor' to buy a 30% stake in the company. Nothing more has been said on this topic since then though.

The highlighting of the recent shutdown is likely to be a public relations exercise intended to project stability, but that focus on clinker is telling given that the government introduced its Export and Investment Promotion Levy in July 2023. This legislation imposed a 17.5% fee on imported clinker in order to encourage the local industry. Cement producers that rely on imported clinker - including Rai Cement, Bamburi Cement, Savannah Cement, Ndovu Cement and Riftcot - attempted to lobby against the levy but it remains in place. This business environment helps to explain EAPCC’s renewed focus on clinker production.

One company that stands to benefit from the levy is National Cement, producer of the Simba Cement brand and a subsidiary of Devki Group. It made the news at the start of April 2024 when its subsidiary Cemtech commissioned a 6000t/day clinker plant at Sebit in West Pokot. National Cement already operates an integrated plant near Athi River, south of Nairobi. However, hot on the heels of the West Pokot plant, it is already considering building another integrated plant in the north of Kitui County, to the east of Nairobi. As reported in the local press this week, Cemtech has submitted an environmental impact assessment for the project to the local authorities.

The country has two other clinker producers: Holcim subsidiary Bamburi Cement and Mombasa Cement. The former company announced at the end of 2023 that it had signed a contract to build solar plants at its integrated plant in Mombasa and its grinding plant in Nairobi. The deal was framed as a money saver but additionally it may have been in response to a less than reliable local grid. It also said that it was removing Ordinary Portland Cement (OPC) from its product line from the start of 2024. This move challenged expectations about sustainability initiatives outside of richer countries. Yet, considering how Bamburi Cement argued against the clinker levy, there might have been some commercial thinking here too in order to sell products that use less clinker. Finally, despite completing its divestment of Uganda-based subsidiary Hima Cement for US$84m in March 2024, Bamburi Cement reported a loss of US$2.99m in 2023 compared to a profit of US$1.36m in 2022. Although it reported a rise in turnover and operating profit, it appears that taxes and legal costs related to the sale of Hima dragged the company into a loss.

It’s been a difficult business environment in Kenya over the last decade given the number of companies that have faced serious financial difficulties. This list includes ARM Cement, EAPCC and Savannah Cement. The last of these companies, Savannah Cement, is currently in administration and is trying to sell its integrated plant. Yet, rolling annual cement production in Kenya has remained above 9.5Mt/yr since early 2022. The government is sticking to promoting local clinker production, and companies like Bamburi Cement, EAPCC and National Cement are making investments of varying scales. The focus, for now at least, is on clinker production in Kenya.

Germany: Buzzi subsidiary Deuna Zement plans to invest €350m to install a carbon capture system at its cement plant in Deuna, having completed two feasibility studies. The Thüringer Allgemeine newspaper has reported that, when operational in 2029, the system will capture 620,000t/yr of CO₂. This will make the Deuna cement plant carbon neutral. The company has applied for government funding for the project.

Buzzi Unicem said that its subsidiary is ‘Doing pioneering work on the path to decarbonising the cement industry.’ It added “The system will be efficient and take all relevant environmental considerations into account.”

Nigeria: Finland-based Wärtsilä has signed a 10-year operations and maintenance (O&M) agreement for a captive power plant that provides the energy for Mangal Industries’ cement plant located in Kogi State. The cement plant has limited access to the local electricity grid and its power plant operates with five Wärtsilä 34DF dual-fuel engines delivering an output of 50MW. The O&M agreement is designed to ensure that the facility can reliably maintain its cement production target of 3Mt/yr.

The 10-year agreement starts immediately as the unit commences operations in the second quarter of 2024. It will run on liquid fuel initially but then switch to gas operation when a natural gas pipeline is commissioned. The power plant’s dual-fuel engines can be operated both on liquid fuel and natural gas. They could also be potentially converted to operate with low- or zero-carbon fuels in the future subject to availability.

Patrick Borstner, Director, Operations Africa at Wärtsilä Energy said, “Wärtsilä now has more than 400MW of installed capacity for the cement industry in Nigeria, and we are operating three captive power plants in three different states. This successful track record clearly indicates our capabilities and highlights the added value we can deliver to our customers through our experience and expertise in supporting their operations.”

Mangal Industries signed a contract with China-based Sinoma International Engineering in 2021 for the construction of a 3Mt/yr new integrated cement plant. Construction at the site commenced in mid-2022.
