This work was carried through with intention to present solutions techniques for a beer industry, giving a viable destination to its generated residues. The Project aims at to reaproveitar these residues for the production of biogs through biodigestores, and thus to make possible the use of the same as half of if converting this biogs into electric energy, brightening up the generated ambient impacts. 1. INTRODUCTION Currently diverse industries of innumerable branches, are if dedicating to the related questions the support. Ones of the forms to make with the same ones becomes each time more sustainable is to consider alternative solutions in set with better gerenciamentos of its rejeitos, similar to improve them economically, socially and ambiently. With the purpose to minimize the impacts caused for the generated liquid rejeitos with the manufacture of the beer, and to promote the development and the efficient use of the biomass generated I assist with it of biodigestores, and thus to apply technologies to convert gas generated in electric energy as sustainable source. The present project to interdisciplinar has as objective to carry through sustainable techniques, integrating knowledge acquired in and integral, Physical Differential calculus applied and Chemical Analytical, you discipline then given.
