This paper summarizes the methanogenesis process, the environmental requirement, kinetics, energy requirements, and methane production cost of methane fermentation systems. Available data of biodegradability of the residue and kinetic equations can be used to predict the methane production under different operating conditions. The optimum condition for fermenting beef cattle residue is operating at a thermophilic temperature (55/sup 0/C) with an influent concentration of 80 g of VS/L. This produces yields of 3.96 L of CH4/L fermenter-day at 5 days retention time. It is apparent that the anaerobic fermentation process is technically feasible. However, only at plant sizes larger than 300 Mg TS/day will the anerobic fermentation system produce methane gas comparable to the current natural gas price. If the effluent can be used as a feed supplement for livestock, the anaerobic fermentation system for livestock residue will be economically feasible at a plant size between 3 and 6 Mg TS/day. This corresponds to beef cattle feedlots between 1000 and 2000 head.
