This article intend to present some considerations directed to electricity generation with small systems (microturbine and conventional engines ), using biogas generated by sewage treatment process in SABESP (Basic Sanitation Company of São Paulo State), located at Barueri, Brazil. This project, pioneer in Latin America, is being accomplished together with BUN - Biomass Users Network of Brazil (proponent), in association with CENBIO - Biomass Reference National Center (executer), with patronage of FINEP / CT-ENERG (financial backer), by means of CONVENTION No: 23.01.0653.00, regarding to ENERG-BIOG Project - "Instalation and Tests of an Eletric Energy Generation Demonstration Unit from Biogas Sewage Treatment". The study is being done at Barueri Sewage Treatment Plant.This plant operate with anaerobic digestion process, which has as mainly products biogas (composed mainly by methane) and sludge. Part of the methane produced at the anaerobic process is burnt in a boiler being used to increase digestors temperature. The rest of the methane is burnt in flare to reduce the impacts caused by gases emissions. This article presents some technical, financial and environmental project results, related to the exploitation of sewer biogas for power generation, as well as bigger details about generation systems (biogas microturbine), used in the facility.
