Sustainable solid waste management has gained a great of interest at the present time, because it endows with the reduction of environmental impacts, the conservation of natural resources and the utilization of biogas generated from the decomposition of wastes as a source of potential energy. In order to achieve this sustainability, in Mexico there has been a substantive progress in the closure of the open dumps and the construction of landfills, whose operation, age and composition of wastes, determines a variation in the degradation of wastes and a differential production of biogas. This research was carried out in the closured dump and the landfill of Morelia, in order to analyze the composition of solid wastes and to determine if there are statistical differences between both sites and the time of confinement of solid wastes. To achieve this, waste samples were taken at different depths and characterized the components; an analysis of variance and Tukey test were applied to data from the analysis of composition. Results of composition and statistical tests show differences between strata and sites. These findings are relevant to take into account for the calculation of biogas in dumps and landfills.
