Sustainable transition towards biomass-based cement industry…
Policy intervention points to achieve a sustainable transition are proposed. Cement manufacturing is a hard-to-abate industrial sector that accounts for 5–8% of global anthropogenic emissions. Approximately 80–90% of these emissions occur during limestone calcination and fuel combustion processes. Decarbonising these two emission …

Cement Plants: Coke
Cement Plants: Coke. Coal-derived coke was the fuel used in most static kilns and so was the dominant fuel in the cement industry in the nineteenth century. Coal could not be used in static kilns in which the fuel is fed in with the raw material, mainly because, during the gradual heat-up of the charge, the fuel's volatiles are lost without ...

Cement
Cement emissions intensity has remained relatively stable since 2018, at just under 0.6 t CO 2 per tonne of cement produced, following several years of modest increase largely due to an increasing clinker-to-cement ratio in China. To get on track with the NZE Scenario, emissions must fall by an average of 3% annually through to 2030.
