Most cement emissions do not come only from burning fuel. Much of the CO₂ is chemically locked inside limestone.Dr. Erin R. Bobicki, co-founder and CEO of CURA, joins Lydia Chen to explain how the company aims to separate that CO₂ before the limestone enters the cement kiln.Using the familiar reaction between vinegar and chalk, Erin breaks down CURA’s electrochemical pre-calcination process: electricity produces acid and base, the acid releases a concentrated stream of CO₂ from limestone, and the remaining calcium can still be used to make cement.They explore:• Why cleaner kiln fuel cannot solve cement’s full emissions problem• How CURA captures CO₂ before the kiln• The volcano experiment that makes the chemistry understandable• CURA’s pathway from laboratory work to commercial deployment• How carbon pricing is changing the economics of cement• Why climate technology must also be the best business decision• The experience in northern Labrador that changed Erin’s directionCURA says its process could reduce cement-production emissions by up to 85% and manage the carbon at cost parity with conventional cement manufacturing.Since this conversation was recorded, CURA has announced that its 5 kg/day mini-pilot is operational:https://curaclimate.com/press/curas-mini-pilot-is-operationalLearn more about CURA:https://curaclimate.com/Explore Bite-Size Climate Tech:https://www.dayzeroproduction.com/bite-size-climate-techSupport Season 5:https://www.dayzeroproduction.com/bite-size-climate-tech/supportFigures, commercial claims, and deployment plans discussed reflect CURA’s statements at the time of recording.
