Based on the National Solid Waste Policy, the Brazilian port sector was forced to manage the waste generated in ports and port terminals. From the inventory of waste, it was possible to analyze the efficiency in the generation of waste in port terminals that predominantly handle the general cargo, using the Data Envelopment Analysis (DEA) method. The output-oriented DEA BCC model was adopted. In addition, this work used three analyzes, one general and two peer-to-peer. The result of the general analysis, in which the three variables were considered, presented eight efficient terminals, having one false-efficient terminal. The DMU 18 was the most efficient because it obtained the highest value in the Normalized Compound. In the peer-to-peer analysis, the efficient border was formed by only two DMU's, where the presence of DMU 21 is observed in the three analyzes. Moreover, in one of the peer-to-peer analyzes it was observed that the model attributed the highest value in the Normalized Compound to the DMU 20 that was not efficient. In this case, the composite and normalized composite indicators were disregarded from the analysis, using standard and inverted efficiency indicators. This article includes the identification of the terminals with the best and worst management practices.
