A biological process in which biodegradable organic matters are broken down by bacteria into biogas, which consists of methane (CH4), carbon dioxide (CO2), and other trace amount of gases. The biogas [..]

a collection of processes by which microorganisms break down biodegradable material in the absence of oxygen. It is used to produce renewable energy in the form of a biogas.

A biological process that produces a gas principally composed of methane (CH4) and carbon dioxide (CO2) otherwise known as biogas. These gases are produced from organic wastes such as livestock manure [..]

Organic matter broken down by bacteria in the absence of air, producing a gas (methane) and solid (digestate). The by-products can be useful, for example biogas can be used in a furnace, gas engine, turbine or gas-powered vehicles, and digestates can be re-used on farms as a fertiliser.

The system for dealing with organic wastes is a complex biochemical process, which takes place in the absence of oxygen, producing a mixture of carbon dioxide and methane gas and a reasonably stable g [..]

AD is a biological process that happens naturally when bacteria breaks down organic matter in environments with little or no oxygen. Almost any organic material can be processed with AD, including waste paper and cardboard (which is of too low a grade to recycle, e.g. because of food contamination), grass clippings, food, agricultural waste, indust [..]

  Digestion of materials in the absence of oxygen. See

Electricity production primarily from farm and food waste.

Degradation of organic matter by microbes in the absence of oxygen to produce methane and carbon dioxide.

The conversion of non-woody biomass by micro-organisms in the absence of oxygen into biogas and digestate.

The use of anaerobic bacteria in a biodegrable process to breakdown waste, with biogas as a valuable byproduct

 – The decomposition of the organic matter in sewage sludge by micro-organisms into methane, carbon dioxide and water, in the absence of oxygen.

A treatment process in which wastewater solids and water (about 5 percent solids, 95 percent water) are placed in a large tank (the digester) where bacteria decompose the solids in the absence of diss [..]

A biochemical process in which bacteria break down biodegradable organic material, such as manure, in an oxygen-free environment. Temperature, moisture, nutrient content and pH, can be controlled thro [..]

A biochemical process by which organic matter is decomposed by bacteria in the absence of oxygen, producing methane and other byproducts. (05 Dec 1998)

A process in which organic matter is degraded by a microbial population of bacteria in the absence of oxygen.

the biological degradation of organic materials in the absence of oxygen to yield methane gas (that may be combusted to produce energy) and stabilised organic residues (that may be used as a soil addi [..]

Organic matter broken down by bacteria in the absence of air, producing a gas (methane) and solid (digestate). Aerobic digestion
