Cement Plants CoalCO2 Emissions Profile of the US Cement Industry
London coal gas production began in and by was producing 300 000 tons of coke a year so coke was also readily available and being essentially a waste product was cheaper than coal Early cement plants used coal for drying slurry and for power generation and coke for kiln burning Per tonne of clinker produced consumption was Cement production also is a key source of CO2 emissions due in part to the significant reliance on coal and petroleum coke to fuel the kilns for clinker production Globally CO2 emissions from cement production were estimated at 829 MMTCO2 in 7 approximately 34 of global CO 2 emissions from fossil fuel combustion and cement production
