Based in California and founded in 2006, Blue Planet converts CO2 to carbonate and then turns it into limestone rock, which is then incorporated into concrete. This process allows Blue Planet to secure clients that can use the product in buildings, sidewalks and bridges. This way, the CO2 is permanently sequestered in infrastructure instead of being released into the atmosphere. In California, Blue Planet’s products have been used on projects at San Francisco International Airport, Levi’s Stadium, and the San Francisco-Oakland Bay Bridge. It is also working with cement manufacturers in Mexico and Canada, along with power plants in Wyoming.
