Clinker production is the most energy-intensive step in the cement production. Temperatures over 900°C transform the limestone (CaCO3) into lime (CaO), thus releasing CO2. This is called the calcination process. The calcinated raw meal reaches temperatures of up to 1450°C which allow its sintering to form clinker.
