Use of Alternative Fuels Industrial Efficiency

Conventional fuels like hard coal and lignite that are commonly used fuels in cement production have high specific CO2 emission values (Hard coal ~95 kg CO2/GJ; Lignite ~98 kg CO2/GJ). Consequently, substituting these with other fuels having lower specific emssion values (e.g. fuel oil or natural gas) or with other sources that can satisfy the thermal demand of the processes is an effective
