Global cement production accounts for 7% of annual greenhouse gas emissions in large part through the burning of quarried limestone. Now, a CU Boulder-led research team has figured out a way to make cement production carbon neutral—and even carbon negative—by pulling...
The U.S. Department of Energy’s (DOE) Advanced Research Projects Agency-Energy (ARPA-E) has awarded the CU Boulder engineers and their colleagues at the National Renewable Energy Laboratory (NREL) and the Algal Resources Collection at the University of North Carolina...
Researchers at the University of Colorado Boulder have developed a way of using algae to create carbon-neutral or even carbon-negative concrete. The researchers use biogenic lime limestone grown by algae instead of quarried limestone to make Portland cement,...
“We don’t have to change anything about Portland cement production,” he says. No new equipment is required, and the product already meets existing standards. This could cut emissions by 60%, or, if combined with other changes, exceed 100%.”
The startup spun out of the University of Colorado Boulder’s Living Materials Laboratory, has received seed investment from SOSV and has already supplied samples of its “biogenic” limestone to partners in the cement industry, such as Microsoft.
