The residual oil proceeding from frituras is considered as one of the domestic residues villainous of the ambient pollution. Beyond generating serious problems of bad hygiene and I smell, the oil presence and fats in the sewer net, cause the clogging of the same one, making it difficult its functioning what consequently it comes to generate the negative ambient impacts, a time that stop being carried through the removal of the oil, are used chemical products, what it results in the comprometimento of the quality of the water exactly after to have been done a treatment of sewer. Another caused impact is of impermeability of the ground, since it is about a substance that possesss low interaction with water, hindering that the same one executes its cycle in the ground, affecting aquatic renewal of freticos sheets and sources that depend on this phenomenon. Another observed fact is that when entering in contact with aquatic sources the oil cause a serious which had problem, to be lighter than the water, the oil finishes being in surface and, with this, resulting in the creation of a barrier that makes it difficult the entrance of light and the oxygenation of the water, thus compromising, the base of the aquatic alimentary chain, ' ' fitoplnctons' ' (ALBERCINI & BRIDGES, 2004). Moreover, when played the opened sky, for if dealing with a organic composition, the same it comes to suffer decomposition for microorganisms, thus resulting in the methane emission in the atmosphere, and contributing consequentemente for the effect greenhouse, had its molecular geometry, since it is possible to hold back up to twenty times more energy that the carbon dioxide. Coarsely, many commercial establishments (restaurants, bars, snack bars, pastry shops, hotels, panificadoras) and residences of Rondon of Par play the used eatable oil in the ground or the net of sewer. The implantation of this project for the reaproveitamento of the used oil in frituras in the Panificadora Venice becomes thus necessary, in which according to LAW N.
