This article reviews the potential of anaerobic digestion ( AD ) for biogas production from livestock manure wastes and compares the operating and performance data for various anaerobic process configurations. It examines different kinds of manure waste treatment techniques and the influence of several parameters on biogas and methane yield. The comparison indicates that a variety of different operational conditions, various reactor configurations such as batch reactors, continuously stirred tank reactor ( CSTR ), plug flow reactor ( PFR ), up‐flow anaerobic sludge blanket ( UASB ), anaerobic sequencing batch reactor ( ASBR ), temperature phased anaerobic digestion ( TPAD ), and continuous one‐ and two‐stage systems, present a suitable technology for the AD of livestock manure waste. Main performance indicators are biogas and methane yield, degradation of volatile solids ( VS ), higher loading, and process stability with a short retention time.
