Engineers at Stanford University have created a process that converts atmospheric carbon dioxide into a durable construction material with strength comparable to concrete. The technique uses a modified calcium silicate that rapidly absorbs COâ‚‚ and transforms it into calcium carbonate crystals, creating a solid material. Unlike concrete production, which generates significant carbon emissions, this process is carbon-negative. “Each ton of our material removes approximately 1.7 tons of COâ‚‚ from the atmosphere,” notes Dr. Aisha Patel, who led the development. The team is now scaling up production for commercial applications.
