Methane Generator from Waste Materials

A new anaerobic digestion system that naturally converts biomass waste material into methane gas is proposed by the referenced technology. Manure is used as the main input which can also be used in combination with other forms of organic waste material. Managing manure has been a persisting challenge for dairy farmers. According to the U.S. Department of Agriculture a dairy cow produces approximately 80 lbs. of manure per day. Considering that an average dairy farm can have 150 cows farmers have to manage 6 tons of manure on a daily basis. Such high concentrations of manure not only pose waste management problems within the farms but also generate unpleasant odors and pathogens that can affect human and cattle health. Organic waste dumped in landfills decomposes and produces methane. If the methane emission is not contained it poses a threat of turning into an environmental pollutant. Methane is the second most prevalent greenhouse gas emitted in the United States and 20 times more potent than carbon dioxide in causing global warming. By capturing and utilizing the methane produced from organic waste anaerobic digesters the proposed technology helps in slowing down the rate of global warming due to gas emissions.


• Produces high quality methane that can be used as fuel or for generating electricity. • Byproduct biomasses generated from the digester can serve as high-quality compost.
