2020-6-5partly carbon neutral. In modern cement kilns most of the calcination CaCO 3 s CaOs 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

Cement production has advanced greatly in the last few decades. The traditional fuels used in traditional kilns include coal oil petroleum coke and natural gas. Energy costs and environmental concerns have encouraged cement companies worldwide to evaluate to what extent conventional fuels can be replaced by waste materials such as waste oils mixtures of non-recycled plastics and paper
