Cement kilns could become carbon negative if run on clean energy because limestone absorbs CO2

Isn't it fascinating that cement production, a major source of CO2 emissions, could actually help remove greenhouse gases? Researchers at ETH Zurich found that by using Direct Air Capture technology, cement kilns could significantly reduce their carbon footprint. If powered by clean energy, these kilns could cancel out up to 78% of their emissions! This innovative approach not only captures CO2 but also allows it to be reused in cement production, paving the way for a greener future.
