- 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 gasses including nitrogen, hydrogen sulfide (H2S), hydrogen and others.[1]
- It 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]

Companies
- Biogas Nord - "Biogas Nord is an engineering firm that has specialised in the development, planning, construction and operation of biogas plants since the mid-90s."
- Organic Waste Systems - Produces anaerobic digesters that convert waste and biomass into biogas, including glycerin, a biodiesel co-product.
- Glycerin as biogas feedstock from biopact, 27 December 2006.
- Prometheus Energy - Prometheus Energy captures biogas from waste or low-quality sources such as landfills, stranded gas wells, wastewater treatment facilities, agricultural operations and coalbed methane . They then liquify the gas so it can be used as transportation fuel.
- FirmGreen Energy, Inc. Converts landfill gas into clean fuels such as biogas (CNG), biodiesel, and hydrogen for fleet fueling operations.
- EnviTec Biogas - EnviTec Biogas is a company in the biogas industry in Germany. They finance and manufacture biogas block heat power plants, which use organic wastes to produce heat and electricity.

News
- Tanzanian coffee farmers convert waste water into biogas, 23 April 2007, from the BBC. A bio-gas converter is being tested in Tanzania. The machine that washes and prepares the green beans produces streams of highly acidic wastewater. This water can be fed into an anaerobic digester and converted into biogas. which is used instead of diesel to power the machines.
- Environmental Power announces first delivery of pipeline-quality biogas, 27 March 2007 from Biopact.com. Environmental Power Corporation has announced the first delivery in the USof biogas, produced from manure and other agricultural waste streams, into the natural gas pipeline.
- Jenbacher Biogas Engines Power Methane-to-Energy Plant in India, 28 February 2007 from Renewable Energy Access. "A GE Energy Jenbacher biogas engine is powering a demonstration cattle manure-methane cogeneration plant at a dairy complex in Punjab, India, helping to address the region's mounting energy and environmental needs."
- 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.
- NGO brings biogas to the poor in India and becomes member of the Chicago Climate Exchange 24 January 2007 from Biopact. "Andhyodaya, an NGO based in Kerala, India, which promotes biogas production among poor farmers, has become the first Indian member of a United States-based private climate exchange... Andhyodaya's 20,000 small-scale biogas projects have led to cuts equivalent to 40,000 tonnes of carbon dioxide -- or the annual emissions from about 8,000 cars."
- Prometheus Produces World's First Commercial LNG from Landfill Gas; Targeted for Public Transit Fuel 26 January 2007 from Green Car Congress. Prometheus Energy Company has begun producing liquefied natural gas (LNG) from the world's first landfill gas-to-LNG plant in California. The liquified biogas will be used as an alternative fuel in public transport vehicles.
- 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.
