UAE/UK: The Global Cement and Concrete Association (GCCA) has welcomed the launch of the Canada/UAE co-led Cement Breakthrough Initiative at the COP28 climate conference in Dubai on 6 December 2023. Prior to the launch of the initiative, the GCCA hosted a roundtable for representatives of the cement industry and governments.
GCCA chief executive officer Thomas Guillot said "We support and welcome the launch of the Cement Breakthrough Initiative. Cement and concrete are essential for so much of our modern world and will also be needed for meeting the challenges ahead. They will play a key role in providing resilient and sustainable infrastructure and safely housing communities around our planet. Our member companies are fully committed to a net zero future – and it will take the combined efforts of industry and government to deliver on this commitment. This is the decade to deliver, and we are delighted to work with the Cement Breakthrough Initiative and the government of Canada to accelerate the transition."
UAE: Emirates Steel Arkan (ESA) has appointed consultancy A³&Co. to help plan and implement decarbonisation initiatives at its 5.7Mt/yr Al Ain cement plant in Abu Dhabi. The collaboration will focus on reducing CO2 emissions and costs, in line with the Science-Based Targets Initiative (SBTi)’s 1.5° Pathway for Net Zero and in conformity to the EU’s Carbon Border Adjustment Mechanism (CBAM).
ESA is committed to reducing its CO2 emissions by 40% between 2018 and 2030, and to achieving carbon neutrality by 2050.
Paebbl trials 100t/yr carbon-storing cement reactor
30 November 2023Finland/Netherlands/Sweden: Paebbl has commenced production of its carbon-storing cement using its new 100t/yr Obelix reactor. The company says that the trial represents a 100x scale up of its capacity in under six months. The Obelix reactor produces cement in 500l batches. Paebbl’s cement has a CO2 storage capacity of 200kg/t. It expects to begin shipping samples to early adopter customers in the Benelux and Nordic regions from early 2024. The next scale-up for the company will come with the construction of a continuously operating pilot plant in late 2024, further increasing its cement capacity by a factor of 10.
Europe: Germany-based Heidelberg Materials has announced the launch of EvoZero carbon captured net zero cement. The company produces EvoZero cement at its Brevik cement plant in Norway. It says that this is the first cement to achieve net zero CO2 emissions through the use of carbon capture and storage (CCUS), without relying on other methods of compensation in its carbon accounting.
Heidelberg Materials chair Dominik von Achten said “The launch of our unique EvoZero products is a paradigm shift in the decarbonisation of our sector. Carbon capture and storage is a breakthrough technology for the building materials industry and we are frontrunners in deploying it at scale. With EvoZero, we are offering the industry’s most innovative, globally unique product for our customers, enabling them to drive cutting-edge, environmentally friendly construction projects. I am very proud of the dedication and passion of everyone involved in our pioneering project in Brevik.”
Canada: The Cement Association of Canada (CAC) says that provisions for investments and supportive measures in the government’s Fall Economic Statement 2023 will help to ensure the successful roll-out of carbon capture, utilisation and storage (CCUS) for industrial decarbonisation. The statement commits the government to advancing a CCUS Investment Tax Credits (ITC) scheme.
CAC president and CEO Adam Auer said “We commend the government’s recognition of the importance of CCUS in achieving our climate objectives. The cement industry is committed to reducing its carbon footprint, and these investments will facilitate the deployment of innovative technologies that are essential for achieving our Concrete Zero sustainability action plan objectives.”
UAE: The director of the World Cement Association (WCA), Ali Emir Adiguzel, told listeners at the association’s 6th Annual Conference in Dubai that the world has ‘enough cement for the next 25 years.’ Adiguzel addressed the issue of overcapacity by noting a ‘substantial’ drop in demand and pointing out that high input costs had led the sector to raise its prices, by as much as 15% in Europe. He also said that the primary challenge facing the cement industry was “meeting stringent emission targets and embracing carbon capture technologies.”
Adiguzel added "Despite our achievements, there is more work to be done in the years to come. To reach our net zero goal by 2050, we must significantly reduce carbon emissions. The technologies and mechanisms for this endeavour appear available, though currently minuscule and not economically fully feasible. Regulatory frameworks must evolve to minimise costs for end customers. Collaboration between the private and public sectors is imperative to facilitate carbon reduction."
US Department of Energy grants C-Crete Technologies US$2m
17 October 2023US: The US Department of Energy has awarded C-Crete Technologies US$2m in funding. C-Crete Technologies is developing a method for using CO2 captured at industrial sources or from the air as an ingredient in its cement-free concrete. The binder will produce almost no CO2 and continue to absorb more CO2 from the air over time. It offers scalability and cost-parity with conventional cement for concrete producers, according to the developer.
C-Crete Technologies president Rouzbeh Savary said “We are committed to crafting a cement-free, carbon-negative ready-mix concrete that doesn’t just mitigate CO2 emissions but actively contributes to reversing climate change. Our aim is nothing short of revolutionising this hard-to-abate, carbon-heavy sector.”
India: A report by the Council on Energy, Environment and Water (CEEW), funded by power provider BP, has estimated that India’s cement and steel sectors will require capital expenditure (CAPEX) investments of US$627bn in order to reach net zero CO2 emissions. The report stated that waste heat recovery (WHR) and other efficiency-enhancing upgrades to cement plants can immediately reduce the industry’s emissions by 32%.
United News of India has reported that CEEW CEO Arunabha Ghosh said "Incentivising renewable energy will play a pivotal role in decarbonisation, through lower or no transmission charges at central and state levels. The government of India should develop a policy for and expedite the establishment of a carbon capture, utilisation and storage ecosystem to abate more than half of the emissions from the existing steel and cement plants.” Ghosh added “Since hydrogen will play a key role in its implementation, the next phase of the National Green Hydrogen Mission should focus on this agenda."
Tarmac and Cambridge Electric Cement participate in trial melt of Cement 2 Zero carbon neutral cement project
03 October 2023UK: The Cement 2 Zero project has successfully concluded its first trial melt of recovered cement paste in an electric arc furnace at the Materials Processing Institute’s Teesside campus. The project uses the paste as flux for electric steel recycling. Cambridge Electric Cement (CEC) has demonstrated that the ‘slag’ from this process can be ground into fine clinker that, when mixed with gypsum and supplementary cementitious materials (SCMs), produces net zero CO2 cement. The Cement 2 Zero project to produce CEC’s cement at an industrial scale launched in March 2023, with US$7.85m in funding from UK Research and Innovation. Tarmac will grind the clinker from the project’s trial melts for testing in order to obtain certification and specification as a usable cement product.
Holcim invests in Neustark
20 September 2023Switzerland: Holcim has invested in CO2 mineralisation technology developer Neustark. Neustark aims to remove 1Mt of atmospheric CO2 by 2030 and sequester it in recycled construction and demolition waste. The company’s technology achieved Gold Standard certification as a method of CO2 removal in March 2022. Holcim says that its investment advances its group commitment to putting clean technologies to work towards achieving net zero.
Holcim’s Europe regional head Miljan Gutovic said "At Holcim, we are working to decarbonise building for a net zero future, and Neustark's technology helps us reach this goal. After the successful demonstration of Neustark's solution in Switzerland, we are ready to scale up this carbon removal technology globally."
