North America: A new coalition for the scaling and deployment of low-carbon building materials, the creation of new clean cement and concrete jobs and the promotion of environmental justice launched earlier in January 2024. Called the Decarbonized Cement and Concrete Alliance (DC2), it comprises alternative cement developers Biomason, Brimstone, Chement, Fortera and Terra CO₂, sequestration company Blue Planet Systems, circular concrete producer CarbonBuilt, biogenic limestone producer Minus Materials, hydrothermal processing technology developer Queens Carbon and electrified cement production technology developer Sublime Systems. DC2’s areas of engagement in policy will include tax credits, standards, ecolabeling and subsidisation, in line with the US Department of Energy’s Pathways to Commercial Liftoff: Low-Carbon Cement strategy.

CarbonBuilt’s government and community affairs manager Sal Brzozowski said “DC2’s platform of robust policy, standards and incentives to scale innovative solutions will not only accelerate deep decarbonisation, but also transform the concrete industry from one of the world’s largest CO₂ emitters to one of the world’s largest carbon sinks.”

Switzerland: McKinsey & Company and the World Economic Forum have recognised Holcim’s ECOCycle recycling technology for construction-demolition material (CDM) as a "Circularity Lighthouse in the Built Environment." ECOCycle technology can process 100% of CDM input into new building materials with 75% lower CO₂ emissions than traditional alternatives.

Chief sustainability officer Nollaig Forrest said “Circularity is a game changer to decarbonise buildings at scale. At Holcim we are operating over 100 ECOCycle recycling centres globally to drive circular construction. With our advanced recycling of CDM, we can already reduce the CO₂ footprint of cement by up to 40%. This is just the beginning; as we innovate and partner across the value chain to evolve building norms, we aim to accelerate the shift to circular construction in all metropolitan areas where we operate.”

Brazil: Votorantim Cimentos and Atlas Renewable Energy have launched a joint venture to build a 470MW solar power plant in Paracatu, Minas Gerais. Additionally, the parties signed a power purchase agreement (PPA) for the supply of 100GWh/yr of solar energy for Votorantim Cimentos' cement plants between 2026 and 2041. The moves align with the producer’s aim to achieve 75% renewable energy reliance in its operations.

Iraq: Al-Riyadh Investment Companies Group subsidiary Al-Douh Iraqi Company for Cement Industries plans to expand its Al Douh cement plant’s capacity by 58% to 3Mt/yr. The expansion is part of an upgrade involving the installation of a new kiln, a gas-fired captive power plant and a new waste heat recovery (WHR) plant. The WHR plant will provide 30% of the plant’s energy. The US-based International Finance Corporation (IFC) has loaned Al-Douh Iraqi Company for Cement Industries US$130m on a long-term basis for the project.

The IFC says that it expects the Al Douh cement plant expansion to help boost economic diversification, spur sustainable growth in Iraq and generate 2700 new jobs in Muthanna Governorate.

Latvia: Schwenk Latvija plans to build a 750,000t/yr carbon capture system at its 2Mt/yr Brocēni cement plant. The producer has hired Norway-based Capsol Technologies to conduct a CapsolEoP carbon capture feasibility study at the plant. Schwenk Latvija is a member of the CCS Baltic Consortium, which achieved provisional inclusion on the European Commission’s list of Projects of Common Interest in November 2023.

Schwenk Northern Europe CEO Reinhold Schneider said “Checking the best carbon capture methods and how they can be integrated with our production process is a crucial task for us on the way to carbon neutrality, and likely the major investment direction for the coming decade. To that end, we are excited to investigate the energy consumption and the scale of equipment required for carbon capture at the Brocēni plant, if potentially partnering with Capsol for this challenge.”

Capsol Technologies CEO Jan Kielland said “We are excited to work with Schwenk, one of the most innovative building materials producers in Europe, which has constantly improved its processes to reduce emissions since operations started at the Brocēni plant’s new kiln line in 2010” He added “With this feasibility study, we are taking another step towards building a position as the preferred carbon capture technology provider for cement.”

Capsol’s project pipeline includes 10 large-scale cement projects in the sales engineering and engineering studies phase. The total CO₂ capture capacity of these projects is 11Mt/yr.

Germany: Rohrdorfer Zement has fired up a pilot clay tempering unit at its Rohrdorf cement plant in Bavaria. The project has received Euro8.65m in funding from the German Federal Ministry for Economic Affairs and Climate Action and the EU. It is one of a number of industrial projects under the EU’s Euro800bn NextGenerationEU post-Covid-19 economic recovery instrument. Sources of heat for the pilot unit at the Rohrdorf cement plant include waste heat from the plant’s clinker line. If the pilot succeeds, the introduction of tempered clay into cement production at the site will follow. This will entail the construction of an on-site full-scale clay tempering plant. Rohrdorfer Zement says that this would reduce the plant’s CO₂ emissions by 16 – 18%, or by 30% if it achieves carbon neutral clay tempering through the use of green hydrogen.

Rohrdorfer’s dedicated Net Zero Emissions Labs team is working to turn the Rohrdorf cement plant carbon neutral by 2038. Other initiatives include the installation of carbon capture systems at the Rohrdorf plant and another in Austria, and participation in the H2-Reallabor Burghausen hydrogen partnership.

Regarding the latest pilot, Rohrdorf Net Zero Emissions Labs project leader Helmut Leibinger said “As a cement component, tempered clays make a significant contribution to CO₂ mitigation. With the pilot project of process-integrated tempered clay, we are taking not just a step in our decarbonisation roadmap, but a leap.”

Oman: Middle East Calcined Clay and Netherlands-based Kaolin Group International plan to build a limestone calcined clay cement plant in Oman. The partners have hired Spain-based turnkey plant engineer IPIAC to supply equipment including its Plug and Clay clay calcination unit. The new plant will produce limestone calcined clay cement with 40% lower CO₂ emissions than ordinary Portland cement (OPC), according to the supplier.

IPIAC previously introduced the technology in Cuba and Ivory Coast, and is currently retrofitting it to a clinker line in Angola.

India: JSW Cement has appointed Finland-based Coolbrook to install its RotoDynamic Heater electric kiln technology at the Vijayagar steel works and slag and cement grinding plant in Karnataka. Press Trust of India News has reported that the partners expect the technology to reduce the CO₂ emissions of the plant’s slag cement.

US: Sublime Systems has acquired a site in Holyoke, Massachusetts, to build its first commercial-scale cement plant. The planned unit is expected to be commissioned in 2026, create 70 jobs, and will eventually have a capacity of 30,000t/yr. The selected site previously housed paper mills and is powered by local hydroelectric resources. The project is also being supported by a state tax credit from the Economic Development Incentive Program and local Tax Increment Financing from the City of Holyoke to offset property taxes. The commercial-scale plant is being developed as a stepping-stone before building a larger 1Mt/yr plant in the future.

Sublime Systems chief executive officer and co-founder Leah Ellis said “The same qualities that made Holyoke a world-class industrial hub in the past perfectly position it to now be the home for clean tech manufacturing of the future.” She continued, “The Water Street site exemplifies that in its ample space, industrial zoning, access to renewable hydroelectricity, utilities and even rail.”

Sublime Systems is commercialising an electrolysis cement production process that will manufacture cement at ambient temperature from a variety of calcium sources. Its Sublime Cement product received an ASTM C1157 designation in September 2023. The company has raised over US$50m from a consortium of climate technology investors, Advanced Research Projects Agency-Energy (ARPA-E) funding and strategic investor Siam Cement Group.

EU: Cembureau has published its manifesto for industrial transformation for the European Parliament’s 2024-2029 legislative term. The manifesto calls for an ambitious EU agenda focused on the implementation of the European Green Deal along five key lines: 1 - turbo-charging EU and national funding and developing national industrial decarbonisation plans; 2 – Rolling out the EU Carbon Border Adjustment Mechanism (CBAM) to create a level playing field for EU industries; 3 – Building a pan-European CO₂ capture network and moving towards circular carbon feedstocks; 4 – Placing circular economy at the heart of industrial decarbonisation; 5 – Enhancing the EU buildings’ agenda to significantly cut emissions.

Cembureau said “The European cement industry was one of the first sectors to present a 2050 Carbon Neutrality Roadmap following the publication of the European Green Deal. The past five years were marked by the development of a comprehensive EU legislative framework and the launch of significant decarbonisation investments in our industry. Now, with the deployment of carbon-neutral cements within our grasp, we need to implement transformative measures on innovation, infrastructure, public acceptance, digitalisation and skills development.”
