Ireland: In a move towards sustainability, the Irish government has mandated green procurement requirements for low carbon cement, effective from September 2024. This initiative is part of Ireland's goal to achieve a net-zero carbon society by 2050.

The new regulations require a 30% reduction in clinker use and the elimination of high clinker cement for all government and public works. Additional provisions include the necessity for Environmental Product Declarations and comprehensive life-cycle greenhouse gas emissions assessments for major new projects. This aims to significantly reduce CO₂ emissions from the construction sector.

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."

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

Europe: Cembureau has released an update to its net zero roadmap. The roadmap now aims for a 37% reduction in CO₂ emissions related to cement production by 2030, 78% by 2040 and net zero cement production by 2050, with potential to become carbon negative.

The roadmap also states the key policy measures needed to meet these updated goals, including: The implementation of a watertight carbon border adjustment mechanism (CBAM), the increase in funding for decarbonisation initiatives, the need for guaranteed access to affordable decarbonised energy, infrastructure and raw materials, as well as the creation of lead markets for low carbon, circular products.

President of Cembureau, Ken McKnight said "In the past four years, the European cement sector has clearly moved from ambition to deployment. We have the potential to scale up our climate ambition, but we need policymakers to match this ambition through decisive policies."

Jamaica: Caribbean Cement is allocating US$8m, 20% of its planned US$40m investment in 2024, to increase sustainability efforts at its Rockfort plant. The company is aiming to become net-zero by increasing its use of alternative fuels and repurposing materials like tyres, which will also help to save on operational expenses and fuel costs, according to the company.

The repurposing of tyres, which commenced following a Government of Jamaica partnership, will remove a ‘significant’ portion of the estimated 1.5m tyres at the country’s Riverton dump, along with other materials such as pallets, which Caribbean Cement now uses as alternative fuel sources in the cement manufacturing process. With the help of its XRC3000c shredder obtained from Austria-based company UNTHA, Caribbean Cement said it has shredded more than 9000 tyres to date.

Managing director Jorge Martínez said “At the moment our first goal for the end of 2024 is to at least reach 10% alternative fuels. We will remove some of those fuels that are not renewable, substituting it with ones that are. This is part of our future in action programme. Some of these actions are also related to the reuse of some materials in the plant as we take waste materials from other industries and beach clean-ups for repurposing. We try to reuse them in any way we can.”

US: Cemex, in collaboration with the Mission Possible Partnership (MPP) and supported by the Bezos Earth Fund, is undertaking an analysis of decarbonisation strategies at its Balcones cement plant in Texas, US. This initiative is part of Cemex's broader goal to achieve net-zero CO₂ emissions by 2050. The analysis will explore various technological pathways including the use of alternative fuels, incorporation of lower-carbon materials, carbon capture and storage and the utilisation of captured carbon for producing synthetic fuels, chemicals, or construction materials. The partnership focuses on innovations such as substituting traditional fossil fuels with waste, renewable gas, biomass, hydrogen and electrification in the cement production process.

CEO of Cemex, Fernando González said “Our collaboration with the Mission Possible Partnership represents a joint effort seeking to accelerate our sustainable commitments and comprehensively evaluate the extent to which we can utilise decarbonisation levers within a specific plant ecosystem. This involves leveraging scalable technologies that would contribute to achieving our ambitious decarbonisation goals on the path to becoming a net-zero company by 2050.”

UK: C-Capture has initiated a carbon capture trial at Heidelberg Materials’ Ketton cement works in Rutland, as part of its national 'XLR8 CCS' project aimed at accelerating low-cost carbon capture solutions in industries like cement and glass. The trial utilises C-Capture’s technology, which employs a solvent to selectively capture CO₂ from emissions. According to the company, this process does not rely on the use of amines, therefore requiring 40% less energy than conventional methods and reduces costs. The carbon capture solvent compatibility unit designed by C-Capture and partner Wood will test the effectiveness of this technology in removing CO₂ from flue gas emissions produced during the cement manufacturing process.

XLR8 CCS is funded with €2m from the Department of Energy Security and Net Zero’s €1.2bn Net Zero Innovation Portfolio. The funding is part of the €23m Carbon Capture, Usage and Storage (CCUS) Innovation 2.0 programme aimed at accelerating the deployment of next-generation CCUS technology in the UK. Additional private sector contributions support a €3.1m total.

C-Capture CEO Tom White said "Decarbonising industry is one of the most pressing global issues. C-Capture’s XLR8 CCS project is a critical step in the race to net zero as we work with our innovative technology and leading industry partners to demonstrate that an affordable carbon capture solution is a reality – even for industries that are difficult to decarbonise. We are incredibly proud to be working with our project partners which have strong commitments to decarbonisation and are early adopters of novel carbon capture technology."

Simon Willis, CEO of Heidelberg Materials UK said “Carbon capture is a critical part of our strategy to decarbonise cement production and essential if we are to reach net zero and help our customers achieve their own decarbonisation goals. Our venture with C-Capture is another example of our commitment to developing new technologies and, if successful, has the potential to be rolled out at other sites across the Heidelberg Materials Group.”

Thailand: Chair of the Thai Cement Manufacturers Association (TCMA), Dr Chana Poomee, announced the company’s new strategy, called 'TCMA Synergising the Actions toward Net Zero 2050'. This strategy aims to drive the cement industry towards clean energy transition, connect with global green funds and address climate change.

The vision involves four key missions for 2024-2026, including developing low-carbon cement, enhancing resource-efficient mining practices, building an integrated waste-to-value ecosystem, and transitioning to clean energy.

The TCMA also aims to reduce its CO₂ emissions by 6.9Mt/yr by 2030. Collaborations with various partners, including the Thailand Fellowship Cement Manufacturers and the Thai Bankers Association, are planned to leverage innovation and government policy support.

Switzerland: ABB and Captimise have enhanced their collaboration, focusing on advancing cost-effective carbon capture, utilisation, and storage (CCUS) technologies in the cement industry. Under a new Memorandum of Understanding, the partnership will develop various studies, including screening, feasibility, and FEED, aiding cement producers to identify efficient carbon capture solutions across their operations. The joint effort is expected to bolster the cement industry's efforts to meet its climate and net-zero targets.

CEO of Captimise, Mattias Jones, said “We draw on a track-record of more than 25 live case studies with CO₂ emitters across Europe and the US and know we’ll be able to support operations of all sizes in cement through combined CCUS, automation and electrification technologies.”

Global Business Unit Manager at ABB Process Industries, Max Tschurtschenthaler, said “Reducing the CO₂ emissions from cement manufacturing is a major challenge and a top priority for this industry. We are on a mission to make it more cost-effective. By combining our world-class automation, electrification and digital technologies with the know-how of partners like Captimise, we can further support the cement industry in achieving their climate and net zero targets.”

Switzerland: The decision of the Swiss government in June 2023 against the implementation of a Carbon Border Adjustment Mechanism (CBAM) has been strongly criticised by the Swiss cement association, Cemsuisse. The association warns of a potential relocation of the Swiss cement industry without such a mechanism, referencing a report by Polynomics. This report concludes that a Swiss CBAM is necessary to level the playing field with EU and non-EU cement suppliers. The EU initiated a CBAM test phase in October 2023, aiming to mitigate production relocation risks to countries with less stringent environmental regulations.

The federal government concluded that a CBAM in Switzerland would benefit few emission-intensive industries at the expense of the wider economy, while also facing regulatory and trade policy risks. It plans to reassess the need for a CBAM in mid-2026, in line with the EU's interim CBAM report.

Cemsuisse, referencing the Polynomics report, states that waiting to potentially introduce a CBAM in Switzerland is not an option. Investments in carbon capture and storage (CCS) are deemed essential for Switzerland's net-zero climate goal and without a CBAM, there is a risk of these investments being unviable due to uncertainty over cost recovery.

The report also points to the risk of increased clinker imports from third countries into the EU, which would be processed and then exported to Switzerland without CBAM levies. As an example, Cemsuisse mentions a planned milling station in Ottmarsheim, Alsace. It says that without a CBAM, the production site in Switzerland faces serious threats.

Cemsuisse said “Without CBAM, this certainty is lacking. And without CCUS, long-term production in Switzerland won't be viable. The population has accepted the climate protection law last summer, where the net-zero goal is legally anchored."
