A process for production of methane gas in higher yields and higher rates by thermophilic or mesophilic anaerobic digestion of plant material and/or organic waste in admixture with an extract of different plant material. Increases of methane yield of greater than about 25% and up to about 500% are obtained by addition of the extract of different plant material to a normally low biodegradable plant and/or organic waste material before anaerobic digestion thereof. The resulting methane yields and production rates are higher than those obtained by the sum from anaerobic digestion of the individual components when using the extract as taught by this invention.
