In modern cement kilns, most of the calcination (CaCO 3 (s) CaO(s) + CO 2 ) is carried out in the precalciner, and the process conditions there make it a good reactor for combustion of alternative fuels like RDF. However, most waste-derived fuels have a poorer quality than coal, and this could negatively affect the process.
