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.”

Bahamas: Partanna Global has unveiled its first carbon negative, climate-resilient Home for the World in Nassau. The residence will remove 182.6t/yr of CO₂ from the atmosphere. It is the first of 30 planned units, as part of a project to eventually build 1000 Homes for the World in partnership with the Bahamian government.

UK: Heidelberg Materials UK commissioned its new Sutton Courtenay ready-mix concrete plant in Oxfordshire on 17 October 2023. Local press has reported that the plant is equipped with a waste management system for concrete washout and a rainwater harvesting system.

US: Cemex USA has poured 18,300m³ of Vertua reduced-CO₂ concrete in the construction of the Centennial Tower at Houston Methodist Hospital in Texas. Cemex USA says that it successfully completed the 20hr pour at the world’s largest medical complex without interrupting surrounding emergency services.

President Jaime Muguiro said “Cemex’s purpose of building a better future comes to life when we participate in projects that improve people’s quality of life, particularly in the area of health services, in the communities in which we serve. Not only are we providing expert logistics and resilient materials, but we are also providing an alternative to lower the carbon footprint of the project with our more sustainable solutions.”
