CONTENT What is biogas What is anaerobic digestion Biogas sources How anaerobic digestion works Biogas digester Biogas digester operation tips Biogas application

What is Biogas Gaseous by-product from anaerobic digestion of organic material Formed through bacterial metabolism Relatively efficient process -60-85% methane, 15-40% CO2, <1% hydrogen sulfide Nutrients are retained as an organic fertilizer

What is Anaerobic Digestion Anaerobic digestion definition The breakdown of biodegradable materials in the absence of oxygen

Biogas Sources

How Anaerobic Digestion Works

Biogas digester

Any equipment that is used to produce biogas Continuous system where waste is added continuously Batch system where waste is added and is completely digested and the slurry is removed and the process is repeated Single stage where the whole process is done in one tank Two stage where the process is done in two different tanks
