In places where energy is scarce or not available enough for the development of many activities, the use of briquettes based on animal or plant biomass can very well help to meet that need. The residues of the coffee, cocoa and wheat production called husks and at the same time agglutinated with residues of potato and molasses, were used for the preparation of briquettes that presented good calorific value with an average of 9909.59 Kcal / Kg (cocoa), 9912.81 Kcal / Kg (coffee) and 9928.11 Kcal / Kg wheat), respectively.
