The Increasing population expansions as well as technological advances bring numerous benefits to society, however, such factors can also cause intense impacts to the environment, especially in the generation of solid waste and the problem of its final disposal. The organic residues produced in the residences represent approximately half of all the volume generated per inhabitant / day, not to mention that they present a great amount of nutrients and, therefore, they need techniques that aim at their use. Anaerobic biodigestion is a process of degradation of the organic matter carried out mainly by certain types of bacteria, and being indicated as a sustainable solution for the mitigation of this environmental liability, which is the disposal of solid waste. Therefore, the objective of the present work was to characterize the biomass resulting from this anaerobic process in a biodigester formed from recycled materials, in the focus of sustainable practices, not to mention the verification of the feasibility of organic fertilizer production. Through the results obtained, as indicated by the volatile solids content and the moisture content, the biodigestion process was still in an intermediate state, with indications for a decrease in the consumption of organic matter and its almost stabilization, however, due to the result of ammonia obtained, it is perceived that there is still organic matter to be consumed. In comparison with other bibliographies analyzed there is the possibility of using the material as fertilizer since there are innumerable nutritional benefits to the micro biotic community of the soil and the plants as well.
