Microbial CO₂ Mineralization: Converting Emissions to Calcium Carbonate

Project drescription

At Carbonive, we are developing a robust, nature-inspired way to capture carbon dioxide (CO₂) from heavy industry. Using specially engineered bacteria that thrive at high temperatures, our process captures CO₂ directly from hot exhaust gases and combines it with calcium found in waste products from industry. This turns harmful emissions into a stable, solid material called calcium carbonate, the same substance found in chalk and limestone. Because the process works at high temperatures, it avoids the need to cool down exhaust gases, saving energy and reducing costs. Instead of treating CO₂ and industrial waste as problems, we turn them into a useful product that can be reused in sectors like construction, cement, steel, and paper. The goal is to integrate this technology directly at industrial sites, offering a low-cost, scalable solution that both reduces emissions and creates economic value, helping industry move toward a more sustainable, circular future.
