The rampant generation of waste started to become a growing problem due to the difficulties associated with a correct disposal of waste. In this sense, the energetic use of waste is an alternative that, at the same times that provides a correct disposition, solving an environmental problem, contributes to the diversification of the energy matrix. Among the possibilities of energy conversion, the anaerobic biodigestion allows the conversion of the organic fraction of solid waste into biogas, a methane-rich fuel gas. However, the biomethane production potential is affected by the presence of inhibitory agents, which are compounds that impair the production of biomethane during anaerobic digestion. Knowing the elements that are part of the organic fraction of municipal solid wastes is extremely important for the designing of anaerobic biodigestion process. These elements are present in the inert fraction of the residues. The main objective of this paper was to evaluate the presence of inhibitors agents in the organic fraction of municipal solid waste in the city of Santo André, located at São Paulo state - Brazil. Samples were evaluated through Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM-EDS), after the analysis of fixed and volatile solids (EPA 2540G) of the composition of samples with the organic fraction from three different sources of the Municipal Solid Waste - household wet waste, free markets and Regional Company of Integrated Supply of Santo André (CRAISA), aiming to characterize this kind of organic waste.
