The benefits of using alternative fuels (AFs) in the cement industry include reduction of the use of non-renewable fossil fuels and lower emissions of greenhouse gases, since fossil fuels are replaced with materials that would otherwise be degraded or incinerated with corresponding emissions and final residues. Furthermore, the use of alternative fuels maximizes the recovery of energy. Seven different scenaria were developed for the production of 1 ton of clinker in a rotary cement kiln. Each of these scenaria includes the use of alternative fuels such as RDF (Refuse derived fuel), TDF (Tire derived fuel) and BS (Biological sludge) or a mixture of them, in partial replacement of conventional fuels such as coal and pet coke. The purpose of this study is to evaluate the environmental impacts of the use of alternative fuels in relation to conventional fuels in the kiln operation. The Life Cycle Assessment (LCA) methodology is used to quantify the potential environmental impacts in each scenario. The interpretation of the results provides the conclusion that the most environmentally friendly prospect is the scenario based on RDF while the less preferable scenario is the scenario based on BS.

在水泥行业中使用替代燃料（AFs）的好处包括减少不可再生的化石燃料的使用并降低温室气体的排放，因为化石燃料将被原本会降解或焚化的材料所替代，并相应地排放并最终焚化。残留物。此外，使用替代燃料可最大程度地回收能量。开发了七个不同的球藻，用于在回转水泥窑中生产1吨熟料。这些情景中的每一种都包括使用替代燃料，例如RDF（垃圾衍生燃料），TDF（轮胎衍生燃料）和BS（生物污泥）或它们的混合物，以部分替代常规燃料，例如煤和石油焦。这项研究的目的是评估窑运行中与传统燃料相比使用替代燃料对环境的影响。生命周期评估（LCA）方法用于量化每种情况下的潜在环境影响。结果的解释提供了这样的结论：最环保的前景是基于RDF的场景，而次优的场景是基于BS的场景。
