    The exponential growth of the population brings with it several problems. Among them, a greater demand in the generation of energy of polluting sources and greater amount of residues generated. The objective of this work was to evaluate the energy potential of residues generated in two logging. Samples were collected at two logging sites located in the Metropolitan Region of Recife, in Pernambuco. The first sample obtained consisted of the mixture of dust residues of the species Maçaranduba (Manilkara sp.) And Jatobá (Hymenaea sp.). The second sample was a mixture of residues from two species, Maçaranduba and another unidentified The analyzes were carried out at the Forest Technology Laboratory, Department of Forestry Science, Federal Rural University of Pernambuco. The carbonisations were carried out in a digital muffle with temperature control of the brand MAGNU'S model 0910. The carbonization was performed at a rate of 1.4°C/min. Four carbonizations were performed, two for each sample. For the immediate analysis of the charcoal, the adaptation of the CETEC (1982) to ASTM (American Society for Testing and Materials) standards was used, thus it was possible to determine the contents of volatile material, ashes and by fixed carbon difference, dry basis. Charcoal produced by the mixed waste from two logging had an acceptable ash and ash content. The content of volatile materials is higher than desired and as a consequence has a lower fixed carbon content. The higher calorific value is above the average found in the study of Manilkara sp., Probably because the source material is not only maçaranduba. There was no significant difference between the results obtained by the samples, except for the moisture content.
