Betting on a new way to make concrete that doesn't pollute


Solidia, a cement and concrete technology company, is changing the chemistry of how cement is created that could make the building material cheaper and reduce carbon dioxide emissions. Cement plants create more carbon dioxide than any other manufacturing process, so the American-based company is testing how to use the greenhouse gas to incorporate it into the mixture instead of releasing it into the atmosphere. So far, it can reduce as much as 70 percent of CO2 that is normally emitted from the process and it's faster to make than normal concrete.
