Evaluating and Prioritizing of cement plant pollutant gases based on FDH and CRA models

Control and reduction in environmental pollutants are of a great importance in all countries. In this paper, pollutant gases in the cement industry are analyzed and then prioritized for purposes of control and filtration based on DEA models. Two new radial and non-radial DEA models are proposed to prioritize reduction in total costs and in the effects of pollutant gases. Then, another non-radial model is provided for prioritizing reduction in costs and in the effects of pollutant gases. This prioritization is carried out using free disposal hull (FDH) and central resource allocation (CRA) models considering the types of disease caused by the pollutant gases and the medical treatment costs incurred. Finally, the results of the prioritization of Fars cement industry pollutant gases by all three proposed models are compared with those given by Technique for Order of Preference by Similarity to an Ideal Solution (TOPSIS) method and by FDH models.
