Biogas Production from Human Faece and Community Waste Food

Abstract:

This research had an aim to study the biogas production from human faece and community waste food using batch fermentation process. In this experiment, there were 5 types of ratio between human faece and community waste food which were 1:0, 2:1, 1:1, 1:2 and 0:1 and the raw material is dilute with water in the ratio 1:4. The biogas digester was clear plastic cylindrical tank of 20 liters, base area of 300 square centimeters and height of 30 centimeters. This experiment was performed to analyze the rate of gas generation before and after the biogas composition fermentation and heating value of biogas. It was found that, in the ratio 2:1 of human faece and community waste food, the rate of biogas generation was the highest. In the ratio of 1:0, the methane gas generation was the highest which the gas methane composition is 67.6% higher than the of other animals manure, the rate of biogas generation was 0.59 m³/kg-VS and the heating value was 24,336 MJ/Nm³.
