Anaerobic decomposition

Anaerobic decomposition
EPA Glossary of Climate Change Terms
The breakdown of molecules into simpler molecules or atoms by microorganisms that can survive in the partial or complete absence of oxygen.

Anaerobic Decomposition - Reduction of the net energy level and change in chemical composition of organic matter caused by microorganisms in an oxygen-free environment. (EPA Glossary)

Anaerobic decomposition A process of breakdown of organic molecules to simpler inorganic constituents, that occurs in the absence of oxygen. Analogous structures Organs of different evolutionary origin which perform the same role in different organisms. Angiosperms Flowering plants.

The conversion of soluble and suspended materials into gas during anaerobic decomposition. In clarifiers the resulting gas bubbles can become attached to the settled sludge and cause large clumps of sludge to rise and float on the water surface.

The gas produced from the anaerobic decomposition of organic material in a landfill.
Biological Contaminants
Contamination caused by living organisms either microscopic or larger animals, which can cause health effects.

A colorless, nonpoisonous, flammable gas created by anaerobic decomposition of organic compounds. A major component of natural gas used in the home.

methane A colorless, nonpoisonous, flammable gas created by anaerobic decomposition of organic compounds.
Method 18 A test method which uses gas chromatographic techniques to measure the concentration of volatile organic compounds in a gas stream.

Methane: odorless, colorless, flammable and explosive gas produced by municipal solid waste undergoing anaerobic decomposition. Methane is emitted from municipal solid waste landfills.

Colorless, odorless, nonirritating but highly toxic gas produced by incomplete combustion of fuel, incineration of biomass or solid waste, or partially anaerobic decomposition of organic material.
carbon sink ...

The methane is a flammable gas, chemically identical to the main constituent of natural gas, and can be used as a fuel for heat and/or electricity generation. Biogas is effectively the same as landfill gas, which is produced by the anaerobic decomposition of organic material in landfill sites.
