Researchers have developed a novel solution for trapping carbon in concrete by blending a sustainable, easy-to-grow green ...

Concrete has helped build civilizations for thousands of years, from ancient pyramids to modern skyscrapers. But today, it’s ...

“That algae is actually taking CO2 out of the atmosphere. So if it all works, they’re actually creating a carbon sink in their cement, instead of emissions, which just changes the game.” ...

The researchers use biogenic limestone that is grown by algae in place of quarried limestone to make portland cement, concrete's key and most carbon-intensive ingredient.

Concrete is a huge contributor to worldwide CO2 emissions, ... (SOM), in collaboration with Prometheus Materials, showcases an alternative algae-based block that's far better for the environment.

Bell explained the algae continues to sequester carbon even after it's made into these concrete blocks. The algae also help to make the blocks super-strong using the same process you find in nature.
