Get A QuoteCement Manufacturing Process: Environmental Issues. Incement manufacturing, there are two major sources of CO2 emissions. The primary source (60% of total emissions) is the calcination of limestone (CaCO3). Limestone, when heated to above 900 ºC, converts to quick lime (CaO), releasing CO2. The secondary source (40% of total emissions) is the ...
