Carbon-Neutral Concrete: How does Low-Carbon Cement Production work? |
|
Cement production is responsible for about 8 - 10% of global emissions per year. Roughly 60% comes from the fundamental chemistry of the calcination process and 40% comes from energy to drive the process. The only resource we use more than concrete is water. Like steel, concrete is massively important for modern lifestyle, but we rarely ever think about it.

We'll have a look at technology and players in the low-carbon cement market. Ecocem produces low-carbon Cements based on ground-granulated blast furnace slag. CarbonBuilt injects CO2 during the concrete mixing process, which spurs a chemical reaction that permanently mineralizes CO2 within the concrete. 00:00 - Intro 00:26 - Cement Facts: Climate impact, production volumes, Importance for Civilisation 01:22 - Cement Production Process - How it works 02:14 - Green Premiums - What it takes to reduce emissions and produce carbon-neutral cement 03:47 - Low-carbon Cement Market - Technology and Players 04:16 - Ecocem: Ground-granulated blast furnace slag 05:50 - CarbonBuilt: 06:12 - CarbonCure: Mineralized CO2 sourced from flue gas 07:13 - Solidia Techologies: Portlandite addition (produced at lower temperature) and carbon capture during curing π Your free subscription goes a long way: https://www.youtube.com/@NetZeroTech?sub_confirmation=1 β See you on Patreon: https://www.patreon.com/NetZeroTech π§ Reach out to Katha: kathasepoint@gmail.com βοΈ Buy Katha a coffee: paypal.me/kathasepoint π Thank you for watching! π Let me know your thoughts in the comments! |
