Cement has been the most common material used in all construction projects for decades. The availability of raw materials required to produce cement increases its popularity compared with other construction materials such as steel. It represents the basic ingredient to produce mortar, plaster, grout, and reinforced concrete. Mainly there are four methods for cement manufacturing: dry, semi dry, semi wet, and wet. Although the selection of the manufacturing method depends mainly on the nature of the raw materials and available resources, each method has its advantages and disadvantages. This study aims to evaluate the methods of cement manufacturing in terms of material homogeneity, dust emission, production cost, capital cost, fuel consumption, quality, and Co2 emission using Multi Criteria Decision Making (MCDM). Fuzzy Preference Ranking Organization Method for Enrichment Evaluation (F-PROMETHEE) was used as it is one of the best tools for Multi-Criteria Decision Analysis. The analysis results indicate that the dry method is ranked as the best method for cement manufacturing due to its very low carbon dioxide emission, very low fuel consumption, very low production cost, and very low processing time. The semi-dry method is ranked as the second preferred method for cement manufacturing while the third rank was for the semi-wet method, and the least preferred choice is the wet method due to very high fuel consumption, very high processing time, very high production cost, and very high carbon dioxide emissions.
