Tech Thursday: Carbon Neutral Cement

Engineers from the University of Colorado, University of North Carolina Wilmington, and the National Renewable Energy Laboratory are revolutionizing the production of cement. By replacing mined limestone with micro-algae, they have discovered a way to create carbon-neutral, and potentially carbon-negative, cement. This innovative approach involves growing calcium carbonate through photosynthesis, allowing the plant-made limestone to serve as a sustainable substitute for mined limestone. This groundbreaking research paves the way for a more sustainable and eco-friendly construction industry.
