For this, the SIAD v3 tool was used to determine the efficiency of the processes of these companies from three inputs and three outputs, as relevant criteria for analysis. The CCR and BCC models were applied to compare the results obtained in four groups: standard efficiency, boundary efficiency, composite efficiency and normalized composite efficiency. The results showed that only one of the companies presented efficiency in all four groups. The companies located in the municipality of Marabá present average efficiency above the companies located in Eldorado of Carajás
