Evaluation of biogas potential from organic waste: wastewater and solid wastes

Abstract

Abstract The poor management of waste can lead to multiple environmental problems like in soil, water, and air pollution. Beside the current energy crisis occurs, need alternative energy sources that can replace, one of which is biogas. Biogas is a gas resulting from the fermentation anaerobic of organic materials. The aim of this work is to study to compare the biogas produced from organic waste, namely household waste, sago processing liquid waste and poultry manure. The research was conducted in a laboratory scale anaerobic reactor with a volume of 1,000 mL at room temperature. The results showed that the volume of biogas produced from anaerobic fermentation of sago processing wastewater was 17.481 mL (84 days fermentation). Biogas produced from household waste (7%) is 687 mL, for 35 days. Volume biogas from poultry manure (50%) 1,200 mL (60 days fermentation).
