The PUREFA (Program of Rational Energy Use and Alternative Sources), developed by USP - University of São Paulo and supported by FINEP - Financial of Studies and Projects, consists of 14 purposes and has three main objectives: to introduce measures of management and energy efficiency proceedings; to increase the distributed generation at USP, employing renewable and not conventional energy resources and to introduce permanent incentive polices of efficient and rational energy use. In this project, the CENBIO - Brazilian Reference Center on Biomass is responsible for purposes 11 and 12 that are related to the biogas use for electricity generation. The first one, the 11th has as main objectives to implant the generation system, to capture and to stock the biogas produced by the biodigestor located at the Technological Hydraulically Center (CTH - USP). The biodigestor's type is a UASB (Upflow Anaerobic Sludge Blanket), whose outflow of the biogas produced is near to 4m³/day and operates 24 hours per day, utilizing sewer from the residential buildings located at Sao Paulo University, inside the campus. Nowadays, this equipment is used for biogas treatment researches, the biogas emitted to the atmosphere. In order to use the biogas, it is necessary to identify its outflow, chemical composition and heat value, parameters that will determinate its real potential for generation and will show the necessity of a previous treatment, as H₂S removal. Finished this stage will be started the purpose 12, purpose that regards the biogas use as fuel for electricity generation.
