Making Cement The Way Coral Does It: Out Of Thin Air | Fast Company
Biomineralization expert Brent Constantz of Stanford University got  inspiration from the way corals build reefs to make a new type of cement  for buildings. The process of making this cement actually removes  carbon dioxide – a greenhouse gas, thought to cause global warming—from  the air. The company Constantz founded, called Calera,  has a demonstration plant on California’s Monterrey Bay that takes  waste CO2 gas from a local power plant and dissolves it into seawater to  form carbonate, which mixes with calcium in the seawater and creates a  solid. It’s how corals form their skeletons, and how Constantz creates  cement.
