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

8. 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
