In this study was developed a fermentative process to produce ethanol from green banana non optimal for exportation through one induced endogenous hydrolysis. The potential of the stillage to produce biogas was also evaluated. It was compared the induced endogenous hydrolysis, with the exogenous hydrolysis that uses commercial enzymes and the traditional acid hydrolysis done all of them in a final volume of 1 liter, the reference point was the ethanol produced in the fermentation process. The maximum performance was obtained with the endogenous hydrolysis and with these methodology fermentations at 15 liter as done. The average of ethanol produced was 0.065 liters from one kilogram of green banana and the biogas production was 2.24 liter per liter of stillage. The proposed process shows performance comparable with that obtained by sugar cane fermentation. Also the methodology demonstrated several advantages, such as low cost, simple to operate, and because it constitutes a good alternative, which is environmentally compatible in the area of management of crop residues.
