gas produced from fermentation of organic material, e.g. sewage sludge, organic waste, etc., in rather small units often connected to waste water treatment plants, composed of 65% methane, and carbon dioxide and water; biogas is treated to increase the methane content to about 97%, which is the same as in natural gas; use of biogas for cars or heating gives rise to very small emissions
Gas generated by the anaerobic fermentation of organic matter (dung, plant residues, and so on). It consists of some 60–70% methane. As a renewable energy source, it can be used for heating, lighting and, with suitable adaptation, as fuel for internal combustion engines.
primarily composed of methane, biogas is a principal byproduct of anaerobic treatment that can be used as a fuel.
Biogas is generated when bacteria degrades biological material in the absence of oxygen, in a process known as anaerobic digestion. Since biogas is a mixture of methane (also known as marsh gas or natural gas) and carbon dioxide it is a renewable fuel produced from waste treatment.
Biogas is a mixture of methane and carbon dioxide resulting from the anaerobic decomposition of such waste materials as domestic, industrial, and agricultural sewage. Methanogenic bacteria carry out the decomposition; these obligate anaerobes produce methane, the main component of biogas, which can be collected and used as an energy source for domestic processes, such as heating, cooking, and lighting.
(Methane) A colourless flammable gas consisting of hydrocarbon (CH4) resulting from decay due to the action of anaerobic bacteria.
energy produced from the anaerobic digestion of sewage and industrial waste
Biogas is a mixture of methane and carbon dioxide that is generated when bacteria degrade biological material in the absence of oxygen, in a process known as anaerobic digestion. Biogas can be burned in boilers to produce hot water and steam and to generate electricity. It can also be used as a vehicle fuel.
Gas, rich in methane, which is produced by the fermentation of animal dung, human sewage or crop residues in an airtight container. It is used as a fuel to for stoves and lamps, to run small machines and to generate electricity. Biogas fuels do not usually cause pollution to the atmosphere, and because they come from renewable energy resources they have great potential for future use.
A mixture of carbon dioxide and methane produced through bacterial action.
methane obtained from decomposing organic matter.
Biogas is generated from concentrations of sewage or manure. These are usually in the form of slurry comprising mostly water (almost 95 per cent). The slurry is fed into a digester, either continuously or in batches. Digestion takes from about 10 days up to several weeks, at a temperature of 35°C.
Gas formed by digestion or decomposition of organic materials.
Gas resulting from the fermentation of waste in the absence of air (comprising mainly methane/carbon dioxide)
A combustible gas created by anaerobic decomposition of organic material, composed primarily of methane, carbon dioxide, and hydrogen sulfide.
A gas produced from biomass, usually combustible.
Fuel/gas composed of a mixture of methane and carbon dioxide formed by the decay of organic waste matter.
Gas derived from the anaerobic decomposition of organic matter.
A product of decomposing organic matter such as manure or food processing wastes using anaerobic bacteria. Biogas is primarily composed of methane, carbon dioxide, and hydrogen sulfide. Optimum Utility Systems can design useful applications for biogas such as heating, absorption cooling, and generating electricity using an engine or microturbine.
A by-product of the sewage treatment process that includes carbon dioxide and methane. Melbourne Water uses biogas as a source of renewable energy.
a gas composed principally of a mixture of methane and carbon dioxide produced by anaerobic digestion of biomass
A mixture of methane and carbon dioxide resulting from the anaerobic decomposition of waste such as domestic, industrial and agricultural sewage. a.k.a. gobar.
Combustible gas produced from decomposing biological wastes. Biogas consists of 50 per cent to 60 per cent methane.
A combustible gas derived from decomposing biological waste. Biogas normally consists of 50 to 60 percent methane.
A mixture of methane and carbon dioxide gases produced when anaerobic bacteria break down organic waste.
Natural gas produced from organic matter. Can be purified to produce bio-methane.
The gas produced from the anaerobic decomposition of organic material in a landfill.
a mixture of methane (CH4) and carbon dioxide (CO2), produced by the anaerobic digestion of sludges or organic material in landfill sites; can be used to generate heat or power
the gas produced from decomposition of livestock manure in an anaerobic digester consisting of 60-80 percent methane, 30-40 percent carbon dioxide, and other trace gases such as hydrogen sulfide, ammonia and hydrogen
Biogas typically refers to a (biofuel) gas produced by the anaerobic digestion or fermentation of organic matter including manure, sewage sludge, municipal solid waste, biodegradable waste or any other biodegradable feedstock, under anaerobic conditions. Biogas is comprised primarily of methane and carbon dioxide.
