Artisanal biogas generation of domestic organic waste using waste cooking oil as co-substrate

Abstract

The objective of this study was to measure the methane generation potential of the combination of domestic so lid organic waste and waste cooking oil, through the construction of artisanal biodigesters and an experimentation methodology developed for the project by the author. Both samples of solid a nd liquid wastes were obtained from previous quantification and characterization studies. Five different dosages were administered to each biodigester going from 0% to 8% of waste cooking oil. Samp le 5 was the one with the highest generation (50.48 mg), followed by samples 1 (41.80 mg) and 4 (34.80 mg). The lowest value was presented by sample 2 with only 27,83 mg of methane generatio n.This research shows that the generation of methane in homes in the city of Guayaquil is feasible.
