Cement production releases a lot of CO2 to atmosphere
Maybe there is some twist to help the problem, but...
Carbon concentration in cement spans from 5% in cement structures to 8% in the case of roads in cement.[53] Cement manufacturing releases CO2 in the atmosphere both directly when calcium carbonate is heated, producing lime and carbon dioxide,[54][55] and also indirectly through the use of energy if its production involves the emission of CO2. The cement industry produces about 10% of global man-made CO2 emissions, of which 60% is from the chemical process, and 40% from burning fuel.[56] A Chatham House study from 2018 estimates that the 4 billion tonnes of cement produced annually account for 8% of worldwide CO2 emissions.[57]
Nearly 900 kg of CO2 are emitted for every 1000 kg of Portland cement produced. ...
