In cement production, a significant portion of the thermal energy is used to burn the cement clinker in the rotary kiln. Nowadays, alternative fuels (refuse derived fuels, RDF) are used in parallel with fossil fuels, replacing the former. From an economic point of view, cement manufacturers are striving to increase the share of alternative fuels in order to secure or improve their competitive situation. In addition to economic advantages, ecological advantages should also be mentioned. For example, the use of alternative fuels can contribute to reducing climate-relevant CO2 emissions.
