Aug 31, 2019 Also, the use of fossil fuel in cement production is responsible for the high cost associated with its finished products. As the demand for cement is expected to increase exponentially in the coming years, it is paramount to find alternative ways to reduce the embodied energy and carbon of cement by the use of alternative green fuels.
Producing one ton of cement represents approximately 0.5 ton of CO2 and 100 kg of fossil fuel pet coke. The solid waste is used as an alternative fuel for kilns in the cement production plants. CEMEXs initiative consists of replacing the use of fossil fuels to co-processing of solid waste to energize the cement manufacturing process.
