Reaproveitamento de óleo de cozinha para produção de sabão e biodiesel

Abstract

This academic work intend to identify and make people aware about the disposal of vegetable oil on the academic community and it’s neighborhood, recycling and producing soap and biofuel. Therefore, results obtained from field research were explained, applying the tool (questionnaire), at 7 restaurants and snack bars nears to Universidade Federal de Alagoas (UFAL), to identify the viability of recycling oil, through it’s characterization, to evaluate it’s components and analyze it’s physicochemical properties and organoleptics.The frying oil first passed treatment to remove impurities. Thereafter, it was characterizated, analyzing it’s densidity, humidity, freezing point, acidity and saponification levels and viscosity. Then, biofuel was produced, using the same evaluation parameters previously mentionated to verify it’s quality and also produced soap, attesting it’s organoleptics characteristics, pH, foaming, water resistance and weight loss. Therefore, this study indicated that it is possible not only to give a proper destination a pollutant substance, but to turn it into a high value product, very useful and much less prejudicial to the environment.
