A week ago, there were two fully-financed cement plant carbon capture, utilisation and storage (CCUS) projects underway in the US.¹ Now, there aren’t.

Projects to decarbonise National Cement Company’s Lebec, California, plant and Heidelberg Materials North America’s Mitchell, Indiana, plant were each set to receive up to US$500m in US Department of Energy (DoE) funding on a one-for-one basis with private investments. The projects were to include eventual 950,000t/yr (Lebec) and 2Mt/yr (Mitchell) carbon capture installations. Additionally, the Lebec plant was to transition to limestone calcined clay cement (LC3) production and the use of alternative fuels (AF), including pistachio shells. Both were beneficiaries of the DoE’s US$6bn Industrial Demonstrations Program (IDP), touted by former US Secretary of Energy Jennifer Granholm as ‘Spurring on the next generation of decarbonisation technologies in key industries [to] keep America the most competitive nation on Earth.’ Disbursement of funding under the programme was frozen by executive order of President Trump in January 2025.^{2, 3}

On 30 May 2025, Trump’s Secretary of Energy announced that the government in which Granholm served had approved spending on industrial decarbonisation without a ‘thorough financial review.’ He cancelled remaining project funding in signature Trumpian style, in list form.⁴ Among 24 de-funded projects, Lebec and Mitchell accounted for US$1bn (27%) of a total US$3.73bn in allocated funds that have now been withdrawn.

It's hard not to feel sorry for the management of the Lebec and Mitchell plant and the teams that had been working to deliver these projects. Heidelberg Materials has yet to comment, though CEO Dominik von Achten was in North America in late May 2025. National Cement Company parent Vicat, meanwhile, conceded the setback with a strong statement of its commitment to CO₂ reduction, to 497kg/t of cementitious product globally.⁵ There was a diplomatic edge to the statement too, however. Echoing the Secretary of Energy, Vicat said that its target remains ‘solely based on existing proven technologies, including energy efficiency, AF substitution and clinker rate reduction’ – as opposed to ‘any technological breakthroughs’ like carbon capture. There are currently no public details of possible back-up financing arrangements for these projects; for now, the best guess at their status is ‘uncertain.’

Alongside these group’s local subsidiaries, another organisation that has to do business daily with the DoE is the American Cement Association (ACA). President and CEO Mike Ireland has continually acknowledged the complex needs of the government, while stating the association’s case for keeping support in place. With regard to these funding cuts, Ireland’s emphasis fell on the latter side: “Today’s announcement is candidly a missed opportunity for both America’s cement manufacturers and this administration, as CCS projects have long been supported by bipartisan members in Congress and bipartisan administrations.”⁶ He reasserted the ACA’s understanding that carbon capture aligns with the administration’s strategy to bolster domestic manufacturing and innovation.

The early 2020s heyday of US carbon capture was founded on gradual, consensus-based politics – unlike its demise. Table 1 (below) gives a non-exhaustive account of recent and on-going front-end engineering design (FEED) studies and the funding they received:

Additionally, MTR Carbon Capture, which is executing a carbon capture pilot at St Marys Cement’s Charlevoix plant in Michigan, previously received US$1.5m in Fossil Energy Research and Development funding towards a total US$3.7m for an unspecified cement plant carbon capture study.¹⁰

Market researcher Greenlight Insights valued industrial decarbonisation initiatives under the Office of Clean Energy Demonstrations (ODEC – the now defunct DoE office responsible, among other things, for the IDP) at US$65.9bn in cumulative returns in April 2025.¹¹ The government has yet to publish any account of how it might replace this growth, or the 291,000 anticipated new jobs that would have come with it. Given all this (along with the extensive financial and technical submissions that accompanied each project), the issues raised by the DoE are presumably budgetary, or else founded in a perception of CCUS as essentially uneconomical.

Carbon capture is very, very expensive. A fatuous reply is that so is climate change, just with a few more ‘verys.’ Hurricane Ian in September 2022 cost US$120bn, more than enough to fund carbon capture installations at all 91 US cement plants, along the lines of the former Lebac and Mitchell agreements.¹² Unlike climate change, however, carbon capture remains unproven. Advocates need to continually justify taxpayer involvement in such a high-risk venture.

At its Redding cement plant in California, Lehigh Hanson successfully delivered a funding-free FEED study, with its partner Fortera raising US$85m in a Series C funding. This presents an alternative vision of innovation as fully-privatised, in which the government might still have the role of shaping demand. This is borne out in the IMPACT Act, a bill which ‘sailed through’ the lower legislature in March 2025.¹³ If enacted, it will empower state and municipal transport departments to pledge to buy future outputs of nascent reduced-CO₂ cements and concretes.

A separate aspect of the funding cancellation that appears decidedly cruel is the targeted removal of grants to start-ups. Two alternative building materials developers – Brimstone and Sublime Systems – were listed for a combined US$276m of now vapourised liquidity. Both are commercially viable without the funding, but the effect of this reversal – including on the next generation of US innovators who hoped to follow in their footsteps – can only be chilling. As non-governmental organisation Industrious Labs said of the anticipated closure of the ODEC in April 2025: “We may see companies based in other geographies start to pull ahead.”

Heidelberg Materials’s Brevik carbon capture plant came online in June 2025, 54 months after the producer secured approval for the project. The term of a presidency is 48 months. This probably means that producers in the US will no longer see CCUS as a viable investment, even under sympathetic administrations.

Even as government funding for CCS flickers from ‘dormant’ to ‘extinct,’ the sun is rising on other US projects. Monarch Cement Company commissioned a 20MW solar power plant at its Humboldt cement plant in Kansas on 27 May 2025. The global momentum is behind decarbonisation, even if economics determines that it will only take the form of smaller-scale mitigation measures at US cement plants into the medium-term future. We can hope that these, at least, might include the AF and LC3 aspects of National Cement Company’s plans at Lebec.

Spain: Holcim is exploring the use of char as an alternative fuel in cement production as part of the Plastics2Olefins project, in collaboration with Geocycle. The producer is evaluating char samples made from different types of plastic waste.

Geocycle plant manager Cristina Gómez said “Since char properties can vary depending on the feedstock, the company is conducting detailed evaluations – looking at calorific value, moisture content, heavy metals, halogens, and sulphur levels, among other parameters.”

These full-scale industrial tests aim to understand how char behaves during combustion, how it affects emissions of CO₂, NO_x, and SO_x, and whether it impacts the stability of the production process or the quality of the cement. Char samples produced at the Repsol pilot plant are being tested at two of Holcim’s facilities: the Quality Central Laboratory and Geocycle Albox. Gómez added “These comprehensive tests provide a solid understanding of char’s properties and help anticipate how it will perform in real-world industrial conditions.”

Holcim is also experimenting with blends of char and petcoke to optimise energy performance and environmental compliance.

Pakistan: Cherat Cement has submitted a proposal to Water and Sanitation Services Peshawar (WSSP) to use municipal solid waste from the city as refuse derived fuel (RDF) under a public-private partnership. The company said that approximately 500t/day of waste is collected from Peshawar and currently dumped at a 1.6Mt capacity landfill. The initiative would replace coal in cement production and generate revenue for WSSP while tackling the issue of solid waste management.

Uganda: Hima Cement has said that over 50% of its fuel for cement production now comes from renewable biomass instead of heavy fuel oil (HFO). Head of regulatory affairs David Mugagga said that the biomass used to fuel the kilns at Hima Cement’s plants is sourced from coffee husks, palm kernels, rice husks and sawdust. Mugagga also said that the company collects hazardous waste to use as fuel, reducing the amount that goes to landfill.

Brazil: Votorantim Cimentos has reported that it ended 2024 with global CO₂ emissions of 550kg/t of cementitious material produced, a reduction of 28% compared to 1990, the baseline year used by the cement industry. The level reflects a 1% year-on-year decrease from 556kg/t in 2023. Votorantim Cimentos’ 2030 decarbonisation target, approved by the Science Based Target initiative (SBTi), is 475kg/t of cementitious product.

Votorantim Cimentos’ global thermal substitution rate (TSR) was 32% in 2024, an increase over 2023’s TSR of 31%. Its 2030 target is 53%. The company’s clinker factor was 72.5%, a slight fall compared to 73% in 2023. Its 2030 goal is 68%. 34% of the electricity consumed by Votorantim Cimentos in 2024 came from renewable sources, the same as in 2023. The company’s goal is to have 45% of the energy consumed globally come from renewable sources by 2030.

Álvaro Lorenz, Global Director of Sustainability, Institutional Relations, Product Development, Engineering and Energy, said “Globally, we have made progress in pilot projects for CO₂ capture, installed new co-processing and renewable energy sites and systems, and launched low-carbon products. All these efforts will contribute toward our decarbonisation journey and help us achieve our goal of producing carbon-neutral concrete by 2050.”

Boral announced this week that it had secured around US$15m from the Australian government towards decarbonisation upgrades at its Berrima cement plant in New South Wales. The funding will go towards the company’s own investment in a kiln feed optimisation project. A new specialised grinding circuit and supporting infrastructure at the site is intended to increase the proportion of alternative raw materials (ARM) from 9% to 23% to decrease the amount of limestone the kiln uses. The use of more ARMs should also enable the unit to reduce its energy intensity. Boral plans to use ARMs including granulated blast furnace slag, steel slag, cement fibre board, fly ash and fine aggregates from recycled concrete. Commissioning and full operation of the changes are scheduled for 2028.

The Berrima plant officially opened its last set of changes, including a chlorine bypass unit, in December 2024. This was done to allow the plant to reach a thermal substitution rate (TSR) of 60% by the end of 2027. At the end of 2024 the company said it had a TSR of 30% having risen by 20% from 2023. Another similar decarbonisation project at the plant is a carbon capture and storage demonstration pilot trial involving the recarbonation of construction and demolition waste.

Parent company SGH said in its annual report for 2024 that Boral was continuing to advocate for a carbon border adjustment mechanism (CBAM) to prevent carbon leakage and that it had taken part in the ongoing government review on the issue. This lobbying was visible earlier in March 2025 when the Cement Industry Federation (CIF) publicly addressed the government on the issue ahead of its next budget. It asked that carbon leakage be addressed in the form of an import tax to protect the local cement and lime sector. Cement and lime imports from Thailand, Malaysia, Indonesia, Vietnam and Japan are particularly seen as an issue. The government review into carbon leakage started in 2023 and is due to report back at some point in 2025, most likely after the parliamentary election in May 2025.

Another big sector news story to note is the ongoing acquisition of the cementitious division of the Buckeridge Group of Companies (BGC) by Cement Australia that was revealed in December 2024. Unsurprisingly, the European Commission (EC) approved the deal in late March 2025. Cement Australia’s parent companies Holcim and Heidelberg Materials are headquartered in Europe, but the EC concluded that the planned transaction was unlikely to dampen competition in Europe. The verdict of the Australian Competition and Consumer Commission (ACCC) is likely to be far more telling. It closed taking submissions on the proposed deal in late February 2025 and plans to release an update in May 2025.

The ACCC’s market inquiries letter reported that Cement Australia wants to run BCG Cement. However, under the acquisition proposal, BGC Quarries and BGC Asphalt will be acquired and operated by a new 50:50 joint venture between Holcim and Heidelberg Materials, which will operate as a production joint venture in respect of aggregates. Holcim and Heidelberg Materials have suggested taking four ready-mixed concrete (RMC) plants each in the greater Perth area. Finally, one RMC plant at Wangara could be divested due to the close proximity of existing plants run by Holcim and Heidelberg Materials. Whether this is what actually happens remains to be seen.

Finally, Holcim flagged-up Australia this week as one of the regions it intends to derive ‘profitable growth’ from after the planned spin-off of the US business. This approach is in line with the hunt by the big building materials companies for new growth markets as the cost of merger and acquisition activity in the US has risen. CRH, for example, bought a majority stake in AdBri in mid-2024. Further merger and acquisition activity in the cement sector in Australia seems less likely given its relative small size. Yet the higher economic growth forecast for the country compared to Europe is likely to keep multinationals interested.

Brazil: Votorantim Cimentos grew its revenue and earnings in 2024 but its net income dropped significantly due to interest rate volatility. It noted ‘positive performance’ in its Europe and Asia region and a stable market in Brazil. It attributed its mounting earnings to its balanced portfolio, revenue in Europe and Asia, operational efficiency, reduced costs and new business.

The group’s net revenue grew by 3% year-on-year to US$4.69bn in 2024 from US$4.53bn in 2023. However, revenue fell slightly in local currencies due to negative exchange effects, particularly in North America. Cement sales volumes rose by 1% to 35.4Mt from 34.9Mt. Adjusted earnings before interest, taxation, depreciation and amortisation (EBITDA) increased by 16% to US$1.14bn from US$0.99bn. Earnings rose in all regions except for Latin America due to a ‘challenging’ market in Uruguay and lower prices in Bolivia. Despite this, its adjusted net income dropped by 17% to US$383m from US$461m.

“We ended the year with record-high operating results, supported by our geographic, product and business diversification, in line with our strategic mandate,” said Osvaldo Ayres, the group’s global CEO. The company invested over US$550m in 2024 towards decarbonisation, competitiveness and new businesses. A further US$880m investment plan in Brazil to 2028 was announced in early 2024. Ongoing projects include upgrades supporting higher thermal substitution rates at the Xambioá plant in Tocantins state and the Salto de Pirapora plant in São Paulo. A new 1Mt/yr cement grinding unit is being built at the Salto de Pirapora site. Construction of this project is scheduled for completion in the second-half of 2025. A new 1Mt/yr cement grinding unit was also announced at the Edealina plant in Goiás. This project is expected to be completed in the first half of 2026.

Votorantim also revealed that it paid around US$190m to the Administrative Council for Economic Defense (CADE) at the end of 2024 in connection with an agreement to end all administrative and judicial litigation. It said “We definitively resolved all pending disputes with CADE. We did not acknowledge, at any time, having committed any unlawful act or engaged in any anticompetitive behaviour.”

Finland: Tana Oy has appointed Jari Mennala as its CEO with effect from 5 May 2025. He succeeds Kalle Saarimaa who became the Chief Operating Officer and Executive Vice President of NG Group in February 2025.

Mennala was appointed as the Director of Worldwide Forestry Sales & Marketing and Managing Director of John Deere Forestry Oy in 2024. He has worked for John Deere since 2008 for its forestry division in Finland, the US and the UK. He holds a master’s degree in industrial management from Tampere University of Technology and an executive master’s of business administration from Aalto University in Helsinki.

India: Swachha Andhra Co. chair K Pattabhiram and Andhra Pradesh Pollution Control Board chair P Krishnaiah said cement manufacturers must use refuse-derived fuel (RDF) in kilns as per the Solid Waste Management rules issued by the Ministry of Housing and Urban Affairs in 2018. The regulation requires a minimum RDF usage of 15% to reduce coal consumption in cement production.

Pattabhiram said 7000t of waste is generated daily from 123 urban local bodies, and stressed the need for daily processing to eliminate dumping yards. He urged cement plants within 400km of municipalities to comply. Krishnaiah added that a joint technical committee would be formed to assist cement producers in implementing the rule.

Slovakia: Slovak cement plants recovered 374,000t of alternative fuels made from waste in 2024, replacing 75% of heat from fossil fuels, according to the Cement Manufacturers Association (ZVC) of the Slovak Republic. This has reportedly saved almost 230,000t of coal and reduced the cement plants’ carbon footprint.

Director of ZVC Rudolf Mackovic said “Instead of waste, such as non-recyclable plastics, being deposited in landfills without being used, it is processed into fuel in processing plants. Such an alternative fuel meets strict quality and ecological parameters.”
