This startup is using microalgae to make carbon-neutral 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%.”

Algae-grown limestone provides route to carbon-negative concrete

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, concrete’s key, and most carbon-intensive ingredient.
