Tom Schuler: How we could make carbon

Concrete is all around us: we use it to build our roads, buildings, bridges and much more. Yet over the last 2,000 years, the art of mixing cement and using it to bind concrete hasn't changed very much -- and it remains one of the world's biggest emitters of carbon. Entrepreneur Tom Schuler previews an innovative way to create concrete, potentially turning it into a carbon sink that traps CO2

How Cement Is Made

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
