Learning from Coral to make Cement

Learning from Coral to make Cement

Biomineralization expert and Stanford scientist Brent Constantz has found a way to mimic the way coral builds reefs, by creating cement from carbon dioxide and water. Constantz was inspired to pursue this idea when he learned that for every ton of Portland cement produced a ton of carbon dioxide is emitted. The process in which Constantz is proposing actually removes carbon dioxide from the air. Constantz’s company, Calera, has a demonstration plant on California’s Monterrey Bay that uses 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.
