Global CO2 emissions from the cement sector exceed 2.5 gigatonnes annually. These emissions mainly stem from two sources: about 60% are direct emissions from the chemical reaction of heated limestone (calcination), and around 40% come from the combustion of fuels used in the kiln and plant operations. Additionally, the electricity consumed in cement production contributes to the sector's overall carbon footprint. Efforts to reduce emissions involve multiple strategies applied across the entire lifecycle of cement and concrete. The roadmap identifies specific interventions that will be crucial in achieving net-zero emissions, with the global average performance presented in the graph below. With my background in construction and my experience working with start-ups in sustainable cement and carbon capture sectors, I'm eager to collaborate with more companies in these industries and make a direct contribution toward achieving these targets. #GreenCement #GreenConcrete #SustainableConstruction #CarbonCapture #CCUS #CleanTechnology

Carbon Footprint Assessment of Cement Plant- Carbon Emissions from a Cement plant are divided into two source category: 1) Combustion (40% of emissions) 2) Calcination (60% of emissions) The Combustion- generated CO2 emissions are related to fuel use. The CO2 emissions due to calcination are formed when raw materials (Mostly lime stone and clay) are heated to more than 2500 fernehite and CO2 is liberated from the decomposed minerals. Mitcon Consultancy and Engineering Services Limited provides complete Consultancy for accouting of GHG emissions and prepare road map for GHG reduction to achieve net zero target.

Cement might seem like the least exciting material in the world, but it’s one of the most critical in our fight against climate change. Seriously. It takes burning limestone at nearly 2700°F to make cement, and every step of the process releases CO2. We can’t just stop using cement. So what do we do? We’ve got some ideas. Interested in exploring strategic investments in low-carbon cement solutions? Let’s discuss the details that matter most to you. Reach out to learn more about the opportunities for serious impact and growth. https://bit.ly/4fl66Fi

Revolutionizing the construction industry! 🌱 This algae-based cement is a game-changer, being the world’s first carbon-neutral cement. Unlike traditional cement production, it utilizes biogenic limestone derived from microalgae called Coccolithophores, absorbing CO2 from the atmosphere during its growth. A sustainable solution to combat greenhouse gas emissions from conventional cement production. 🏡 Would you choose this carbon-neutral cement for your home? #GreenConstruction #CarbonNeutralCement #SustainableLiving #InnovationInConstruction #EcoFriendlyHome #AlgaeCement #ClimateAction #BuildingWithPurpose #SustainableMaterials #GreenFuture #EnvironmentallyFriendly

GUEST SUBMISSION: Unless you’re intimately familiar with cement production, odds are the cement industry’s nowhere near your carbon footprint radar, but it’s a top contributor. The production of Portland cement (the concrete industry standard) creates roughly seven per cent of global carbon dioxide (CO2) emissions, which is unsurprising when you realize for each pound of cement produced, nearly a pound of CO2 is emitted. Replacing current cement practices isn’t easy – but it’s also not impossible. Low carbon cement companies have raised hundreds of millions in funding over the last few years as they clamour to be the first to market with a product that checks all the boxes. Some are replacing ingredients; some are introducing carbon capture or “sequestering” technology. When you understand the problem, it’s easier to navigate the potential solutions.

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.

🌍 Decarbonizing Cement: A Major Step for Climate Action 🌍 Manufacturing is one of the top contributors to global greenhouse gas emissions, with cement production alone accounting for about 8% of CO2 emissions each year. As part of Breakthrough Energy’s Five Grand Challenges, addressing cement emissions is crucial. Where do cement emissions come from? 95% of concrete CO2 emissions come from cement production. 2/3 of these emissions are from the chemical process of calcination, where limestone releases CO2. The remaining 1/3 comes from the energy needed to heat the kiln to over 1,400°C. Why is cement hard to decarbonize? It’s cheap and widely used. Its properties are hard to replicate. Strict building codes favor traditional practices. Pathways to reduce GHG emissions in cement: Alternative materials: Use timber, clay, bricks, and non-OPC cement chemistries. Cement use extension: Technologies like CarbonCure and TerraCO2 reduce the need for clinker. Decarbonized energy: Switch to lower emissions fuels and electrification. Carbon Capture and Sequestration (CCS): Capture CO2 emissions at the source. New feedstocks for OPC: Use silicates instead of limestone for carbon-negative cement. With the right innovation and support, we can bring cement manufacturing to net-zero or even net-negative emissions.

Cement is a fundamental BUILDING block of the modern economy (sorry) — it is also responsible for 8% of global emissions. Finding ways to decarbonize cement production is vital to securing a safe and stable net-zero economy. A new ClearPath report, with support from C2ES and Clean Air Task Force, summarizes some simple steps to help accelerate cement decarbonization. The focus of the report? Flexibility and substitutions. Standard-setting orgs and states can offer cement manufacturers greater flexibility to substitute materials with cement-like binding qualities, without the associated emissions. This simple solution could reduce emissions by as much as 70%! In this blog, C2ES Industrial Policy Analyst Tess Moran summarizes the paper: https://lnkd.in/eHvhfS3W You can find the full report here: https://lnkd.in/eeK3wYNn
