Methane recovery from chicken manure digestion

Due to the serious environment problems associated with the large concentrations of manure produced by poultry raised in confinement, the idea of being able to use chicken manure to produce methane and use it as a source of fuel is attractive. This paper discusses the design of an anaerobic chicken manure digestor and the experimental method used to produce methane from chicken manure. The result indicates that 130 liters of gas, 69% of which was methane, was produced per kg of wet manure. The authors conclude that due to strict pollution controls on poultry farms, it is economically feasible for a poultry farm to invest in an anaerobic digestor to produce methane to provide energy for the farm and to control pollution.
