Spain: Çimsa has invested €4.2m in launching a solar photovoltaic power plant to power its white cement plant in Buñol, Valencia. The solar plant has a capacity of 7.2MW and will supply about 18% of the energy needs for the cement plant.
The facility features 11,000 solar panels spread over 100,000m2. This new solar power plant is expected to produce approximately 12GWh/yr of electricity, reducing CO₂ emissions by about 3000t/yr.
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."
Canada: Lafarge Canada and Geocycle Canada have successfully completed a pilot at the Lafarge Brookfield cement plant in Nova Scotia to produce clinker using recycled minerals from discarded material. This pilot can potentially cut CO₂ emissions by 60% of clinker. The new clinker product will be used to produce recycled cement in 2024.
CEO of Lafarge Canada David Redfern said "Our teams have been tirelessly working towards finding solutions to decarbonise our business in Canada. This new recycled-minerals clinker combines operational excellence with circular construction, building new and green from what is considered old and waste. This is a great example of how far we can go - the local team at Brookfield is certainly setting the tone for the industry in Canada."
Since May 2023, Lafarge Canada, Geocycle Canada and the Holcim Group Innovation Centre have been collaborating on a 100% circular production of clinker at the Brookfield plant. The new production method involves substitution of raw materials with lower carbon options from discarded materials, as well as alternative fuels produced from these materials. The trial was performed in February 2024 and cement from this clinker will be produced in 2024 for further testing and development of the technology.
Sweden: Peab has entered a product delivery agreement with Stockholm-based start-up CemVision, starting from 14 May 2024. CemVision has developed a cement that reportedly reduces CO₂ emissions by over 95% compared to traditional cement, by replacing limestone and fossil fuels with refined industrial waste and renewable energy. Over the next few years, Peab will use CemVision's ultra-low carbon cement for various projects, including infrastructure, water treatment, foundation work and prefabricated concrete.
Oscar Hållén, CEO of CemVision, said “We are thrilled to be able to deliver our product to Peab. We see that green cement has become crucial for entire industries to be able to meet their climate commitments. The demand is already enormous and all forecasts indicate that it will only increase.”
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.”
Spain: The Spanish cement manufacturers' association, Oficemen, and Siemens Energy have signed a two-year collaboration agreement to develop decarbonisation techniques and solutions for Spain's cement industry. The agreement was signed by Siemens Energy's Industrial Sales Director for Southwest Europe, Angel Cillerruelo, and Oficemen's General Director, Aniceto Zaragoza.
Zaragoza said "The Spanish cement industry's commitment to climate neutrality by 2050, outlined in our roadmap, includes exploring the most effective levers for emission reduction, such as the decarbonisation of energy sources or the comprehensive energy management of industrial processes."
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.
UK: Seratech has developed a process using olivine, a mineral abundant in Earth's mantle, to produce ‘carbon-negative’ cement. The company's method involves replacing some of the clinker with silica extracted from olivine. Magnesium sulphate derived from the olivine reacts with CO₂ to form nesquehonite, a mineral that sequesters CO₂. This method uses CO₂ captured from emissions sources or directly from the air.
Sam Draper, CEO, explained the process: “The researchers extracted these compounds by dissolving powdered olivine in sulphuric acid. After separating the silica and magnesium sulphate, they bubbled CO₂ through the magnesium slurry to form nesquehonite.”
According to Draper, replacing 35% of regular cement with this silica would yield carbon-neutral results, while a 40% substitution could achieve carbon negativity. Current building standards allow up to 55% of cement to be replaced by this material, although robust testing has yet to be conducted.
Malaysia: Heidelberg Materials has announced its acquisition of ACE Group, a supplier of pulverised fly ash, effective 1 May 2024. Reusing fly ash from energy generation contributes to reducing the CO₂ intensity of composite cement. When used as an additive, fly ash can replace part of the energy-intensive clinker and thus reduce the CO₂ intensity of the cement.
The acquisition includes ACE Greencemt Venture, ASAS Asia and AGP Logistics, with the leadership team from ACE Group continuing to manage the operations post-acquisition. Both parties have agreed not to disclose the financial terms of the transaction.
