A NEW WAY TO USE CO2

Building CO2 emissions represent 60-90% of in total emissions in global cities. On cold mornings in New York City, boilers in the basements of thousands of buildings kick on, burning natural gas or oil to provide heat. Carbon dioxide from these boilers wafts up chimneys and into the air. At the Grand Tier, a 30-story apartment tower in Manhattan, the CO2 from its two giant gas boilers is captured, cooled to a liquid, and then trucked to a Brooklyn concrete factory. There, the carbon is mixed with cement and sealed into concrete blocks. It could also be used to displace petroleum with CO2 in jet fuel and chemical processes. This process provides building owners and operators with a new revenue stream, while ensuring compliance with emissions guidelines.
