  • Biogas is a biologically generated renewable energy that can be produced from organic wastes by simple systems and used for cooking, lighting, heating, absorption refrigeration, etc.
  • Biogas consists mostly of methane (CH4), carbon dioxide (CO2) and a mix of trace gases including nitrogen, hydrogen sulfide (H2S), hydrogen and others.[1]
  • Biogas is produced when biomass decomposes in an oxygen-free environment in a process called anaerobic digestion.
  • It can be burned in its natural form in a variety of applications, and if cleaned can be put directly into the natural gas grid.[2]

  • Hoping for a Green Renewal, Mich. City Will Turn Sewage to Fuel, 2 November 2009 by the Washington Post: Flint, Michigan, "and local Kettering University have teamed up with a Swedish company to turn Flint's municipal sewage into fuel for its bus fleet while reducing or ending the need to incinerate sewage sludge."
    • "The company, Swedish Biogas International, received a $4 million grant from Michigan's Centers of Energy Excellence program to develop the biogas system, which officials hope will begin powering buses by next summer. Producing methane from sewage, landfills and manure is common in the United States, but the gas is more often burned onsite to produce electricity rather than compressed and purified for use by vehicles."[5]
  • Thailand encourages biogas production from cassava and palm oil waste 5 February 2007 from Biopact. In order to encourage tapioca and palm oil processors to utilize liquid effluent waste for energy production, Thailand's National Energy Policy Council has now increased its purchase price of electricity generated from biogas made from Palm oil mill effluent (POME) and cassava processing effluents, from 2 baht per kilowatt/hour to 2.30 baht. This will encourage very small power producers (VSPP) projects and help improve the environmental balance of biofuels made from those feedstocks.
  • Wastewater Plant Turns Kitchen Grease Into Biogas 21 Nov 2006 from WaterandWasteWater.com. Chevron Energy Solutions and the City of Millbrae, California have completed new facilities at Millbrae's Water Pollution Control Plant that uses inedible kitchen grease from restaurants to naturally produce biogas for generating renewable power and heat to treat the city's wastewater. The grease and other organic matter will produce enough biogas at the plant to generate about 1.7 million kilowatt hours annually, which will meet 80 percent of the plant's power needs and reduce carbon dioxide emissions by 1.2 million pounds annually.
