"New modeling reveals that low-carbon concrete developed at RMIT University can recycle double the amount of coal ash compared to current standards, halve the amount of cement required and perform exceptionally well over time. More than 1.2 billion metric tons of coal ash were produced by coal-fired power plants in 2022. In Australia, it accounts for nearly a fifth of all waste and will remain abundant for decades to come, even as we shift to renewables. Meanwhile, cement production makes up 8% of global carbon emissions and demand for concrete—which uses cement as a key ingredient—is growing rapidly." #sustainableconcrete #construction #co2 #materialscience

Concrete is the world's most used construction material, but the 4 billion tonnes of cement produced annually, contributes to 8% of global CO2 emissions. LMG’s patented process utilises fly ash to create, carbon-free Supplementary Cementitious Materials (SCM), an equivalent to Portland cement, and one of its main saleable by-products. By repurposing fly ash instead of allowing it to accumulate in landfills or near coal power plants, we not only reduce waste management at sites but also cut down CO2 emissions.

Switching to cleaner energy sources, using less energy, and adopting renewable electricity can certainly help reduce these emissions. However, here are some alternative ways to decarbonize the cement industry: ✅ Using materials like wood, clay, brick, and new types of cement (e.g., geopolymers) instead of traditional cement can lower emissions. ✅ Reducing the amount of cement in concrete and using materials that require less energy to produce can decrease emissions. ✅ Companies like CarbonCure Technologies and Ecocem Global are developing technologies to inject captured CO2 into concrete and replace part of the cement with other materials. ✅ Carbon Capture and Storage (CCS) involves capturing CO2 emissions from cement production and storing them to prevent release into the atmosphere. ✅ Traditional cement uses limestone, which releases CO2 when processed. Using different raw materials, like silicates that do not release CO2, can eliminate these emissions. #Sustainability #ESG #Cement #ClimateChange #Manufacturing #Carbon

Carbonaide welcomes the European Commission’s delegated regulation draft on recognizing products based on mineral carbonates and used for construction products as a permanent storage for carbon dioxide. 🎉 ✅ CO₂ shall be considered permanently chemically bound in a product through a controlled utilisation process, which allows for the measurement of the amount of CO₂ bound. The CO₂ remains permanently chemically under normal use of the product for a period of at least several centuries. 🚀 Removing the obligation to surrender allowances for greenhouse gas (GHG) emissions that are captured and utilized permanently in a product will provide an impactful alternative for geological storage and result in significant volumes of CO₂ made available for spurring growth in the nascent utilization industry. Carbonaide’s carbon curing technology helps precast concrete manufacturers decarbonize by reducing the cement consumption in daily production by 20-100%. Part of the cement in the process is replaced by CO₂, which is mineralised and permanently stored. In Carbonaide’s scope is generating high quality CDR credits (using biogenic CO₂) for the voluntary markets, as well as unlocking the potential of the compliance markets. #ccus #concrete #decarbonization #constructionindustry

Cambridge Innovation: First-of-its-Kind Zero-Emissions Cement Researchers from the University of Cambridge have developed a zero-emissions method for producing cement, aiming to revolutionize the construction industry's environmental impact. This innovative process recycles old cement from demolished buildings by heating and reactivating its compounds within electric arc furnaces (EAFs). By using recycled cement to replace lime flux in steel recycling, the method prevents waste slag production and creates new recycled cement for concrete, without increasing production costs for concrete or steel. It also reduces emissions in both industries by decreasing dependence on lime flux. Concrete, the second-most-used material globally, accounts for approximately 7.5% of human-caused CO₂ emissions, primarily due to limestone calcination and fossil fuel combustion. The patented 'Cambridge Electric Cement' process has the potential to significantly reduce these emissions, lessen the need for limestone mining, and avoid harmful additives in concrete. With further development and the use of renewable energy, this method could revolutionize cement production, contributing to a sustainable, zero-waste future.   https://lnkd.in/gtCWKPeZ #ZeroEmissions #CementInnovation #GreenConstruction #SustainableBuilding #CambridgeResearch   Image Credit: Pixabay

Innovation to reduce global CO2 emissions in Cement & Concrete Production…

How price competitive are these production technologies already? Is there experience from application? And how do we change procurement procedures in the construction sector to endorse these low-CO2 technologies?

The #FirstMoversCoalition (FMC) is about generating demand for decarbonization technologies - the technologies of the future that exist today and will enable huge swathes of our heavy industries to decarbonize, but which are not yet available at commercial scale / remain prohibitively expensive and in short supply. By making large-scale commitments to purchase products and services made with these emerging technologies, FMC members send a credible demand signal to producers to drive investment into these solutions - ultimately accelerating their deployment. Now we've moved to a new phase of this process - if FMC is about demand, where is the supply going to come from? So starting with the cement and concrete sector, we're taking a look at the suppliers of the future and their innovative solutions for low-carbon cement and concrete. Stay tuned for more innovations to follow. #netzero #concrete #cement Daniel Boero Vargas Jelena R.

How does CarbonCure work? CarbonCure pioneered the mineralization of captured carbon dioxide in ready mix concrete by injecting it during the mixing process. Once injected, the carbon dioxide (CO₂) chemically converts into a mineral and becomes permanently stored there. The mineralized CO₂ also protects the concrete’s strength. This enables concrete producers to adjust the amount of cement content in their mixes while still maintaining concrete strength and performance. This is a win-win solution as CarbonCure’s technologies permanently lock away the CO₂ that has been captured while also reducing the amount of cement needed in concrete production.

Important analysis from Willy Carlsen, Ankita Gangotra, PhD, and Kevin Kennedy at World Resources Institute focused on opportunities for decarbonized cement options to transform the way we produce and use the most common building material in the world. "New innovations are yielding promising technological solutions for cement production, which has historically been considered one of the most challenging of the heavy industrial sectors to #decarbonize. As a key ingredient in #concrete, the primary material in our roads, bridges, homes and offices — and the second-most consumed material on the planet — cement’s massive scale makes it responsible for 8% of global carbon dioxide (CO2) emissions and about 1.5% of U.S. emissions. Reducing, avoiding or eliminating #cement emissions is a difficult puzzle to piece together given the extremely high heat requirements and CO2-producing chemical reactions of its production process, coupled with the material’s low price and the industry’s small profit margins. Meeting the U.S.’s net-zero goals of eliminating climate-harming emissions by 2050 will require the cement sector to decarbonize a lot faster than the current rate, according to the U.S. Department of Energy (DOE)." #embodiedcarbon https://lnkd.in/etkdPWuF
