US: The US Department of Energy has awarded C-Crete Technologies US$2m in funding. C-Crete Technologies is developing a method for using CO₂ captured at industrial sources or from the air as an ingredient in its cement-free concrete. The binder will produce almost no CO₂ and continue to absorb more CO₂ from the air over time. It offers scalability and cost-parity with conventional cement for concrete producers, according to the developer.

C-Crete Technologies president Rouzbeh Savary said “We are committed to crafting a cement-free, carbon-negative ready-mix concrete that doesn’t just mitigate CO₂ emissions but actively contributes to reversing climate change. Our aim is nothing short of revolutionising this hard-to-abate, carbon-heavy sector.”
