The objective of the present work was to quantify and determine the composition of biogas produced by anaerobic biodigestion of stillage in natura and concentraded by Moringa oleifera, using different volumes of industrial slush from a gelatin factory as a source of microorganisms. The experiment was carried out in batch reactors with approximate volume of 125 mL, and controlled temperature (30 ºC) and agitation for a period of 120 hours. Vinasse concentrated and in natura were used, and the treatments had different amounts of vinasse addition every 24 hours. The volume of produced biogas and concentration of gas components (CH4, N2, H2S and CO2) were determined. The objective of the work was to determine the ideal fractionation volume of vinasse for add on the sludge, when inoculating material for biodigestion. The best result was obtained with the most fractionated additions of vinasse, however, should be performed further studies on the use of Moringa oleifera associated with the waste being digested.Downloads
