US: The City of Syracuse, New York, is pilot-testing a new method of infrastructure construction by incorporating recycled glass as a cement substitute in concrete, reports CNY Central newspaper. A patented process by recycling company KLAW Industries crushes glass into fine powder, reportedly replacing 20% of the cement in concrete from recent projects, including upgrades to pavements. The approach follows successful implementations in the City of Binghamton and by the New York State Department of Transportation, with support from SUNY College of Environmental Science and Forestry and Clarkson University.

Department of Public Works Commissioner Jeremy Robinson said "We’re always looking for the most effective and sustainable approaches to constructing and maintaining city infrastructure. Based on the results of this testing, we can determine if the solution can be expanded to more sidewalks and, possibly, other applications.”

US: Cemex USA has supplied 42,800t of its Vertua reduced-CO₂ concrete to property developer Tishman Speyer for Phase 1 of the Mission Rock mixed-use development in San Francisco, California. Vertua concrete offers enhanced sustainability for construction projects compared to conventional concrete through its reduced emissions, energy efficiency, use of recycled materials, water conservation and design optimisation. Phase 1 of the project involved the construction of foundations for two blocks of apartments and an office block. Contractor Webcor first broke ground on the project in 2020.

Cemex USA West Regional President Francisco Rivera said "We are excited to contribute to a forward-thinking project such as Mission Rock by delivering our eco-conscious building materials, advancing sustainability efforts in San Francisco.

US: Icon Build has nearly completed the construction of the upcoming Wolf Ranch new neighbourhood in Georgetown, Texas, using its 14m-wide 5t Vulcan 3D printer. Denmark-based architecture firm Bjarke Ingels Group designed the award-winning development, which will be entirely 3D printed using Icon Build’s high-printability Lavacrete concrete. CNN has reported that that the method of construction addresses on-going local labour and materials shortages.

Icon Build CEO Jason Ballard said "The US faces a shortfall of approximately 5m new homes, so there is a profound need to rapidly increase supply without compromising quality, beauty or sustainability, and that is exactly the strength of our technology.”
