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.
