Biogas Production Simulation of Domestic Organic Waste from Rosana, SP – Brazil:Abstract: The present work has the purpose of verifying the potential of electric energy generation by anaerobic digestion of domestic organic wastes collected in the city of Rosana, SP - Brasil, producing an average of about 1732 kg/day, contributing with a significant amount of greenhouse gases (CH4, CO2, N2, H2S, NH3) where methane (CH4) is 21 times more aggressive than carbon dioxide (CO2), despite this, is a gas with great energetic potential. Thus, anaerobic digestion becomes a viable alternative to reduce methane pollution. The methane production was calculated with a first order rate model and numerical simulation was performed with the open source package Scilab 6.0 ©. The amount of organic waste generated per day in Rosana, considering the total solids of 41% and 64% volatile solids, is capable of supplying 144.2 m³ of methane gas, equivalent to 206.2 kWh/day. This energy can supply the demand for approximately 24 rural residences in Rosana and the biodigestion surplus can be used as fertilizer.
