 The conventional energy source used in cement industries is primarily coal, which has a high environmental footprint. On average, energy expenditures account for 40% of the overall production costs per ton of cement. Reducing both the environmental impact and economic expenditure involves incorporating alternative energy sources such as biomass, solid-derived fuel, SDF, refuse-derived fuel, RDF, etc. Additionally, incorporating additional fuel saving techniques is necessary to make these alternative fuels more efficient. Co-processing and pre-processing are two methods that can help reduce the environmental impact and economic expenditure associated with using alternative fuels. However, incorporating these techniques requires additional investment and effort. Furthermore, older cement plants may not be equipped with the technology needed to make them more efficient. Therefore, it is important to evaluate the performance of a cement plant incorporating AF and develop procedures and recommendations to optimize AF substitution in cement plants. A comparative performance study was conducted to assess the alternative fuel characteristics and equipment performance before and after the incorporation of the alternative fuel. The results showed that the cost to cover one ton of waste input is 10 euros and 90 cents for solid. This article was authored by Asasin Mbighedu, Satyan Riananara, Equa Africoma Armo, and others.
