The company plans to mineralize hundreds of tons of CO 2 a year once it reaches full capacity at its proof-of-concept plant in Pittsburg, Calif. “We make the limestone on land without heat,” says David Gottfried, Blue Planet’s chief commercialization officer. Two carbon-capture startups, Blue Planet and Fortera, are attempting a mineralization technology that uses a natural process that mimics coral reef limestone growth.īlue Planet claims a rate of 44% sequestered CO 2 in every 100 lb of its limestone aggregate. The mineralized CO 2 is permanent and can’t be unleashed into the environment, even if a building is demolished, says Gamble. The process turns the CO 2 into a mineral. Grand-Scale Concrete Sustainability for Buildings Is a Big Productionįounded in 2012, the Halifax, Nova Scotia-based company has 600 installations of its carbon capture-also know as carbon mineralization-systems in concrete producers’ facilities in North America, says Christie Gamble, CarbonCure’s senior director of sustainability.ĬarbonCure producer-partners acquire CO 2 from industrial gas supply companies-usually captured flue waste-and CarbonCure’s systems create a chemical reaction once it’s injected in liquid form into a concrete mix.
