Belgium: The Alliance for Low-Carbon Cement & Concrete (ALCCC) has marked its first anniversary with a new policy roadmap aimed at achieving net zero emissions by 2040. Initiated in May 2023, the alliance brings together environmental NGOs and industry stakeholders to transform the cement and concrete sectors. The ALCCC has grown significantly, now comprising 25 members.
Senior programme manager Joren Verschaeve from ECOS, the coordinator of ALCCC, said "Our members show that the technologies needed to make low-carbon cement and concrete the norm already exist. This uniquely positions our Alliance to raise the alarm when policies and standards lead to unfair competition instead of a greener future – and the latter is perfectly achievable if policymakers implement our roadmap."
US: Sublime Systems has announced the first-ever commercial application of its low-carbon Sublime Cement product at WS Development’s One Boston Wharf building in Massachusetts. The concrete placement is located in the Paseo indoor public space at the office building. The floor will be marked with educational materials explaining the significance of decarbonised cement in combating global climate change.
Leah Ellis, the CEO and Co-Founder of Sublime Systems, said “Buildings are monuments to the values of the people who build them, and the One Boston Wharf project represents WS Development’s leadership in ushering in our post-carbon future.” She continued “They are creating not only the building but the world where people want to be. We are honoured to have Sublime Cement featured so prominently here and are confident this pioneering place will inspire infrastructure owners everywhere to embrace low-embodied-carbon materials as a powerful tool for achieving our global net-zero goals.”
Global: The Global Cement and Concrete Association (GCCA) has announced new collaborations between global cement manufacturers and technology start-ups, focusing on the development of low carbon concrete. Four start-ups—EnviCore in Canada, Queens Carbon and Chement, both in the US and NeoCrete in New Zealand—were part of the 2023 GCCA Innovandi Open Challenge and have now partnered with cement manufacturers. These partnerships aim to reduce the carbon footprint of concrete.
The startups will receive access to industry plants, labs and networks to fast-track their technologies. They will also demonstrate their progress on 6th June 2024 in Bangkok, Thailand, during the GCCA's CEO and Leaders Conference. The association continues its efforts under the 2050 Net Zero Concrete Roadmap, with 29 new start-ups shortlisted this year to work on carbon capture, utilisation and storage (CCUS) technology.
Poor cement market slows CNBM financial results in 2023
03 April 2024China: Poor performance by CNBM’s Basic Building Materials division dragged down the group’s sales in 2023 despite positive performance by the group’s Engineering Technical Services and New Materials segments. Its revenue fell by 10% year-on-year to US$29.1bn in 2023 from US$32.3bn in 2022. Its profit after tax dropped by 33% to US$1.44bn from US$2.13bn. Sales volumes of cement and clinker decreased by 3% to 309Mt from 317Mt. Sales volumes of commercial concrete fell by 5% to 80.8Mm3 from 84.7Mm3.
Revenue for the Basic Building Materials division fell by 19% to US$16.4bn. The company blamed this on a fall in the price of cement, concrete and aggregates although an increase in sales volume of aggregates was noted. The group said that in 2023, the cement industry was characterised by ‘insufficient demand, weakening expectations and weakening off-peak season characteristics,’ coupled with and aggravating surplus and high costs.
Huaxin Cement fights off decline in cement market
03 April 2024China: Huaxin Cement grew its revenue and profit in 2023 by growing its concrete market domestically and increasing its international business. Its revenue rose by 11% year-on-year to US$4.67bn in 2023 from US$4.21bn in 2022. However its operating revenue from cement and clinker declined. The group’s net profit increased by 2% to US$382m from US$373m. Its cement sales volumes grew by 2% to 76.8Mt from 75.3Mt. Concrete sales volumes mounted by 66% to 27.3Mm3.
The share of its international business grew by 16% in 2023 from 13% in 2022. Notable acquisitions in 2023 included the purchases of Oman Cement and InterCement’s assets in Sub-Saharan Africa.
Decarbonising the cement sector in the US, March 2024
27 March 2024The 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).
Company | State | Funding | Scale | Method |
Heidelberg Materials US | Indiana | US$500m | Full | CCS |
National Cement | California | US$500m | Full | Alternative fuels, calcined clay, CCS |
Summit Materials | Georgia, Maryland, Texas | US$216m | Demonstration | Calcined clay |
Brimstone Energy | TBD | US$189m | Commercial | Raw material substitution |
Sublime Systems | Massachusetts | US$87m | Commercial | Raw material substitution |
Roanoke Cement | Virginia | US$62m | Demonstration | Calcined clay |
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.
