Through a simple approach, using carbonated (rather than still) water during concrete manufacturing, researchers have found a new way to sequester CO in concrete. Given how much of this material the world is using, this could be a much-needed boon for sustainability. Concrete problemsConcrete is one of the most widely used building materials globally, yet its production is a major contributor to greenhouse gas emissions. Ordinary Portland Cement (OPC), the key ingredient in concrete, is responsible for about 8% of the world’s anthropogenic CO emissions. If the concrete industry were a country,…
