The manufacture of cement has significantly progressed in recent decades. Commonly employed in conventional kilns are traditional fuel sources such as coal, oil, petroleum coke, and natural gas. The replacement of fossil fuels with alternative fuels (AF) in the manufacturing of cement clinker is highly significant for both cement producers and society. This practice helps to preserve fossil fuel reserves and, in the case of biogenic wastes, decreases greenhouse gas emissions. Moreover, the utilization of alternative fuels can effectively decrease the expenses associated with cement manufacturing. Cement businesses globally are assessing the feasibility of substituting traditional fuels with waste materials, including waste oils, non-recycled plastics and paper mixes, used tyres, biomass wastes, and wastewater sludge, due to rising energy expenses and environmental considerations. The clinker burning process is very compatible with a range of other fuels. The objective is to enhance process control and minimize the use of alternative fuels, all while ensuring the quality of the clinker product remains unaffected. The potential is immense as the worldwide cement industry generates over 3.5 billion tones, which consumes nearly 350 million tones of coal-equivalent fossil and alternative fuels. This study has demonstrated that multiple cement plants have substituted a portion of their fossil fuel consumption with alternative fuels, such as waste recovered fuels. Extensive industrial experience has demonstrated that the utilization of waste materials as substitute fuels by cement plants is both environmentally and economically justified.
