In fact, one ton of cement releases 0.85 tons of carbon dioxide (CO 2), and the concrete industry produces 4-8% of the world’s carbon emissions (3). Currently, no other building material can match concrete’s versatility, low cost, and ease of production, but is there any way to decrease concrete’s carbon footprint while also potentially cutting costs for the industry? Mineral carbonation targets binder compounds; normally, cement is simply mixed with water to form the hydration products which bind concrete’s aggregates together. However, if CO2 is first dissolved in water to form carbonic acid, the hydronium ions from the acid can react with those hydration products to form stable carbonates – in other words, carbon is sequestered through a chemical reaction that stores carbon in concrete’s binding compounds. This process, where CO2 gas is injected into early-age concrete (i.e., at most a few days after mixing) is known as carbonation curing.
# Carbon Capture, Utilization and Storage (CCUS). We've adopted carbon capture storage, a game-changing technology that captures and stores carbon dioxide (CO2) emissions produced during cement production. See the latest news about Heidelberg Materials' carbon capture initiatives. Our investment in Carbon Capture, Utilization and Storage (CCUS) technology at our cement plants in Mitchell and Edmonton positions Heidelberg Materials as an industry leader in sustainability across North America. Carbon capture technology in the cement industry is a method used to reduce the amount of carbon dioxide (CO2) emissions released into the atmosphere during the process of making cement. By implementing carbon capture technology, the cement industry can significantly reduce its greenhouse gas emissions, helping to mitigate climate change. By capturing and storing vast amounts of CO2, we're making significant strides in reducing greenhouse gas emissions and paving the way for a greener future. Our CCUS projects in Edmonton and Mitchell will contribute to Heidelberg Materials’ vision to lead the decarbonization of the cement industry.
How can the steel and cement industry reach net-zero by 2050? By most estimates, steel and cement production account for just over 50 per cent of all industrial emissions (see figure below). GtCO2 emissions from steel and cement production in emerging market and developing economies, 2020–2050. Deep decarbonization of the steel and cement industries will require several parallel strategies: demand management using market creation and circular economy principles, improvements in energy efficiency through technical advancements, and major shifts in production methods and technology.Although some of these technological and process innovations are commercially viable or already in pilot stages, there are currently no commercial-scale sites producing (near) zero-emission steel or cement. Either way, any capital investments in cement and steel are likely to “lock in” the industry’s emissions profile for several decades to come. Although substantial investment is required, it is important to put this into perspective: the Energy Transitions Commission (ETC) has shown that net-zero carbon emissions from heavy industry could cost less than 0.5 per cent of global GDP7.
Unlike other sectors, where the largest share of emissions is energy-related, in cement and concrete production, more than half are process emissions, outlines a newly launched insight report from the World Economic Forum’s First Movers Coalition, in collaboration with Deloitte. However, there are a number of proven ways to significantly reduce the amount of clinker needed to make cement and concrete, and one of the most promising solutions is called LC3 – Limestone Calcined Clay Cement – which can reduce CO2 emissions by around 40% compared with conventional cement. Projections by the Global Cement and Concrete Association show that carbon capture, utilization, and storage (CCUS) could reduce carbon emissions by 36%, making it the largest lever to reduce the cement industry’s emissions. At last year’s COP28 in Dubai, countries agreed to launch the Cement and Concrete Breakthrough initiative, which strives to make near-zero-emission cement production established and growing in every region of the world by 2030.
