This article intend to discuss the electricity generation with 30 kW (ISO) microturbines, using biogas generated by sewage treatment process at 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), by CENBIO - Brazilian Reference Center on Biomass (executer), with patronage of FINEP / CT-ENERG (financial backer), by means of COVENAT No: 23.01.0653.00, regarding to ENERG-BIOG Project - "Installation and Tests of an Electric Energy Generation Demonstration Unit from Biogas Sewage Treatment". This plant operates with anaerobic digestion process, which has as mainly products biogas (composed mainly by methane) and sludge. Currently, part of the methane produced is burnt in a boiler used to increase digestors efficiency process. The rest of the methane is burnt in flare to reduce the impacts caused by gases emissions. An alternative to flare it is the biogas conversion into electricity through engines and microturbines. Thus, this article presents the project results, related with the exploitation of sewer biogas for power generation, as well as bigger details about purification, compression and electricity generation systems (biogas microturbine), used in the facility.
