This grant gives us an excellent opportunity to further develop a new technology to help us all reach our goals.”

Colombia: LafargeHolcim subsidiary Holcim Colombia has launched Eco, a cement bag label detailing products’ CO₂ emissions reduction by comparison to Ordinary Portland Cement (OPC), on its Boyacá Súper Fuerte and Holcim Maestro cements. The La República newspaper has reported that the labels signal the company’s commitment to the Business Ambition for 1.5°C anti-climate change initiative.

Executive president Marco Maccarelli said that the launch is one more step on company’s path towards Net Zero and sustainable construction, engaging the entire value chain.

Germany: HeidelbergCement, Australia-based Calix and a European consortium have chosen the Hanover cement plant in Lower Saxony for the second phase of the LEILAC (Low Emissions Intensity Lime And Cement) carbon capture and storage (CCS) project. The installation will capture 20% of the plant’s capacity or 100,000t/yr of CO₂. The project will take place in three phases, with design completed by June 2021, a complete demonstration installation before the end of 2023 and project completion in 2025. The group previously installed a 25,000t/yr LEILAC CCS system at its Lixhe plant near Liege in Belgium, which completed its test phase in 2020.

Chair Dominik von Achten said, "The LEILAC technology has the potential to enable the cement and lime industries to efficiently capture their process emissions on an industrial scale. The pilot project in Hanover is one of several promising CO₂ capture technologies that we are currently testing at full speed within the HeidelbergCement Group."

Canada: Lehigh Cement and the International CCS Knowledge Centre are conducting a feasibility study looking at carbon capture and storage (CCS) at the Edmonton cement plant in Alberta. The project aims to find out whether capturing 90 – 95% of the CO₂ from the plant’s flue gas is viable. Completion of the study is scheduled for the autumn of 2021.

The Lehigh CCS Feasibility Study will consider an engineering design using carbon capture technology owned by Japan-based Mitsubishi Heavy Industries Engineering (MHIENG), part of MHI Group. The KM CDR process, which is being deployed at 13 commercial plants globally, will be examined for integration with Lehigh’s plant and output specifications, such as a flue gas pretreatment system and the carbon capture and compression process.

The aims of the study are to: deliver a Class 4 cost estimate; to work with a capture technology provider (MHI Group) to perform engineering design tailored to the Lehigh plant; to manage the process and engage third parties, as necessary; to complete a detailed business case; and to develop the budget for Front End Engineering Study (FEED). The project has received US$1.4m in funding from Emissions Reduction Alberta (ERA) through its Partnership Intake Program.

Canada: LafargeHolcim subsidiary Lafarge Canada, Svante and France-based Total have completed Phase 2 of the CO₂MENT carbon capture and storage (CCS) project at Lafarge Canada’s Richmond cement plant. The completed phase consisted of construction and installation of the CO₂MENT technology to capture and filter the flue gas. Lafarge Canada said that Phase 3, scheduled for construction over the next three years, will include the installation of a liquefaction unit, the development of an expansion project to further reduce emissions and a business case review for further expansion across the Lafarge network

Western Canada president and chief executive officer Brad Kohl said “This has been a turbulent year for business and people due to the Covid-19 pandemic with many large scale projects being put on hold, but the perseverance that the people working at the Richmond cement plant continue to show is evident in the success of Project CO₂MENT.” He added “To continue leading change in the building materials industry means we are always looking to partner with like-minded thought leaders such as Svante and Total. This partnership is showcasing our drive towards a net-zero future, and we are seeing this vision become a reality right now with the completion of this phase.”

France: Vicat started using a CO₂ntainer system supplied by UK-based Carbon8 Systems at its Montalieu-Vercieu cement plant in November 2020. It uses captured CO₂ from the unit’s flue gas emissions to carbonate cement-plant dust and produce aggregate, which can then be used to make products such as concrete. The system has particular relevance for a plant burning alternative fuels due to the additional chlorinated dust created compared to the use of conventional fossil fuels. The company says it is the first European cement producer to use the process at an industrial scale. Previously, Carbon8 Systems said that its CO₂ntainer would process and convert up to 12,000t of cement bypass dust in its first phase of operation.

Vicat Group scientific director Laury Barnes-Davin said, “We were drawn to Carbon8 Systems’ two-part technology: capturing the CO₂ that Montalieu emits, and using it to produce an aggregate that can be marketed in the construction industry. It opens up great potential for our operations not just in France but also in all the countries where we work across the globe.” The group hopes to reach a 100% alternative fuel substitution rate in France by 2024.

Spain: The Spanish cement association Oficemen has targeted a 43% emissions drop by 2030 across its entire value chain compared to 1990 levels. The objective has been published as part of the association’s sustainability roadmap to 2050. It is a tightening of the previous target of 27% by 2030. Oficemen intends to meet the tougher reduction by using the so-called 5C approach - clinker, cement, concrete, construction and built environment, and (re)carbonation – as detailed by Cembureau, the European Cement Association. Oficemen also revealed that it is working with the Spanish Technological Platform for CO₂ (PTECO₂) on identifying potential locations for storing captured CO₂. Hugo Morán, Secretary of State for the Environment, participated remotely with the launch event.

Oficemen also reports that Spanish cement consumption fell by 12% year-on-year to 12.2Mt in the first 11 months of 2020. Exports declined by 5%.

Italy: Caltagirone Group subsidiary Cementir Holding has announced the upcoming launch of its FutureCem grey cement product on 1 January 2021. The company says that it has 30% lower CO₂ emissions than normal ordinary Portland cement (OPC). It developed the product in collaboration with its Denmark-based subsidiary Aalborg Portland using 35% limestone and calcined clay to replace clinker. This resulted in a much more sustainable, high grade cement according to the company. It added that the low carbon benefits of FutureCem have been achieved without compromising strength and quality.

Chief sales, marketing and commercial development officer Michele Di Marino said that FutureCem is a ‘giant step’ on the way towards more sustainable cement production. “This is immensely important if we are to achieve our sustainability goals at Cementir Group,” said Di Marino. “But it is also an important contribution to the green transition of the concrete and construction industries in general. Thanks to the efforts of our research and development department in Aalborg, we are ready to begin distributing the FutureCem technology in Denmark and soon other subsidiaries in Europe will follow.” He added, “We have reached an important milestone in our innovation and sustainability efforts, but we are not done. Currently, we are incorporating the technology into more cement types in our product range. This includes white cement, and we have already introduced two white ultra-high performance concrete (UHPC) premix types with FutureCem technology.”

Belgium: Carmeuse has signed a joint development agreement with France-based energy transition specialist ENGIE and John Cockerill for a carbon capture and utilisation (CCU) project in Wallonia. It will concentrate CO₂ from a new type of lime kiln and combine it with ‘green’ hydrogen to produce ‘e-methane.’ The hydrogen will be produced by a 75MW electrolyser plant powered by renewable electricity. The company said, “The produced e-methane will be suitable for injection into the national natural gas grid. This renewable e-methane can be used by industrial users or as an alternative fuel in the transport sector, thus allowing these sectors to decarbonise.”

Construction is due to begin in 2022 for commissioning of the installation in 2025. Its total investment cost is Euro150m. The partners have applied for funding from the EU Innovation Fund and Important Project of Common European Interest (IPCEI) fund. The project’s estimated CO₂ emissions reduction over 10 years is 900,000t

Chief executive officer (CEO) Rodolphe Collinet said, “We are delighted to join forces with John Cockerill and ENGIE for the development of this very exciting and strategic project. It is a major step forward in our ambition to become CO₂-neutral by 2050. This project is a very concrete and important example of Carmeuse’s strong commitment and contribution to sustainable development.”

Norway: The Norwegian Parliament has voted in favour of the government’s proposed grant of funding for industrial scale implementation of full-scale carbon capture and storage (CCS) at HeidelbergCement subsidiary Norcem’s Brevik cement plant. Work on the project is expected to start immediately, with the goal of starting CO₂ separation from the cement production process by 2024. The end result will be a 50% cut of emissions from the cement produced at the plant. The group said that the installation will contribute to its CO2 emissions reduction target of 30% between 1990 and 2025.

Norcem chair and HeidelbergCement Northern Europe regional general manager Giv Brantenberg said, “HeidelbergCement highly appreciates the successful cooperation with the Norwegian authorities. The Brevik CCS project clearly shows the importance of industry and public sector to find common solutions in the fight against climate change.”

HeidelbergCement chair Dominik von Achten said, “We are delighted about the final approval of the Norwegian parliament for our breakthrough CCS project in Norway.” He added, “To meet national and international climate targets, CO₂ separation is an important cornerstone. Our CCS project in Brevik will pave the way for our industry and other sectors.”
