Estudos preliminares da produção de biogás a partir da digestão anaeróbia de resíduos do restaurante universitário do câmpus Medianeira

Abstract

The quest for renewable energy is growing up and large electricity consumption was the factor that pushed this search. There are numerous success cases with the use of organic matter to produce biogas. The anaerobic treatment of residues from restaurants can be an alternative for the production of biogas. In this work it was used the residue of a restaurant with bovine manure in anaerobic conditions. Bioreactor system was built on a laboratory scale for organic waste treatment with bovine inoculum. The experiment was conducted in batch with daily monitoring to detect any change and evolution of the experiment. The results were not positive because there was no production of biogas. After volatile total solids analyzes it was noted that there was degradation of organic matter by bacteria. It was not detected methane in the biogas analysis by gas chromatography. It was concluded that bovine inoculum was not effective in anaerobic digestion of restaurant waste.
