Sustainable transition towards biomass-based cement …
The energy efficiency of cement plants strongly depends on the type of kiln used for clinkerisation [49]. Cement kilns have evolved from long wet kilns to state-of-the-art dry kilns with a calciner, a 6-stage preheater and a high-efficiency cooler. Biomass can be utilised as a fuel in both old wet kilns and modern dry kilns.
