C-Crete Technologies US Department of Energy (DOE) to develop a cement-free, ready-mix, carbon-negative concrete.
Currently, the company is developing a technique to incorporate carbon dioxide (CO鈧�) sourced from industrial emissions or the atmosphere as a component in the concrete product.
The CO鈧�-incorporated product is expected to become the industry’s first pourable concrete to achieve this milestone.
The effort comes after C-Crete debuted its cement-free concrete in a commercial building project in Seattle, US.
C-Crete founder and president Rouzbeh Savary said: 鈥淲e are committed to crafting a cement-free, ready-mix, carbon-negative concrete that doesn’t just mitigate carbon emissions but actively contributes to reversing climate change.
鈥淥ur aim is nothing short of revolutionising this hard-to-abate, carbon-heavy sector of the construction industry.鈥�

By GlobalDataThe company aims to employ CO鈧� in its diluted state to remove the expensive process of separating it from other gases.
The diluted CO鈧� will strengthen the new material when mineralised, enhancing its overall durability and toughness.
C-Crete’s innovation centres on its patented, eco-friendly binder technology, which uses local materials as feedstocks.
This binder emits minimal CO鈧� during production and also absorbs it over time.
Heatherwick Studio technical design lead Stuart Macalister said: 鈥淐-Crete鈥檚 sequestration of CO鈧� into cast-in-place concrete is another aspect with huge potential.
“The consensus amongst climate scientists is that even if we do everything else right to reduce emissions, the world still needs to remove gigantic amounts of CO鈧� from the atmosphere.
鈥淒irect-air capture of CO鈧� is very expensive currently, so other methods, such as those being developed by C-Crete, are vitally important.鈥�
