    The cement kiln is the most significant of these combustion units and typically is fueled with coal. Other fossil fuels are generally too expensive to be used for kiln fuel; however carbon-based waste materials (e.g., solvents, oils, and waste tires) are commonly combusted in the kilns to dispose of the waste, and make use of their energy content
