Decomposition: The break down of organic matter by bacteria and fungi, to change the chemical structure and physical appearance of matter.
Decomposition: The breakdown of matter by bacteria and fungi, changing the chemical makeup and physical appearance of materials.
Decomposition: breaking down into component parts or basic elements.
Decomposition Gases: produced in the breakdown of garbage or other material. Some, such as methane, are flammable.
decomposition The conversion of chemically unstable materials to more stable forms by chemical or biological action. If organic matters decays when there is no oxygen present (anaerobic conditions), undesirable tastes and odors are produced.
decomposition
The breakdown of complex organic substances into more simple organic substances.

The decomposition of organic matter by heating without oxygen or other agents, except for steam-which is sometimes used. Pyrolysis is involved when biomass or waste is converted into synthetic gas.
Decomposition The breakdown of complex, energy-rich organic molecules to simple inorganic constituents. Degradative succession A temporal succession of species that occurs on a degradable resource.
Anaerobic Decomposition- Reduction of the net energy level and change in chemical composition of organic matter caused by microorganisms in an oxygen-free environment.
Animal Dander- Tiny scales of animal skin, a common indoor air pollutant.
Anaerobic Decomposition - Decomposition of cellulose and proteins occurring in the absence of oxygen, such as in landfill waste, producing methane and carbon dioxide.

Biodegradation
Decomposition or breakdown of a substance through the action of microorganisms (such as bacteria or fungi) or other natural physical processes (such as sunlight).
Hydrolysis: The decomposition of organic compounds by interaction with water.
Hydronic: A ventilation system using heated or cooled water pumped through a building.
Hydrophilic: Having a strong affinity for water.
Fossil Fuel A fuel, such as coal, crude oil and natural gas, produced by the decomposition of ancient (fossilized) plants and animals. Fuel cell A technology utilizing an electrochemical process to convert energy into electrical power.
They help natural decomposition of organic matter in water.

Fertility - the quality that enables a soil to provide plant nutrients, in adequate amounts and in proper balance, for the growth ...
Diatom frustules, pollen grains, insects, and other animal remains are preserved in these areas of poor decomposition. These remains are used by paleolimnologists to reconstruct a picture of past plant and animal life and environmental conditions.
Organic matter decomposition generally serves as the most readily available source of nitrogen, phosphorus, and sulfur. Organic matter also serves as an importance source of charge for the retention of cation nutrients.
The controlled biological decomposition of organic material in the presence of air to form a humus-like material.
Methylmercury is released into the water system as part of the decomposition process when large quantities of vegetation are submerged and begin to rot; an unintended consequence of the construction of dams for hydroelectric power.
The substances removed are classified into four basic areas: [1] greases and fats; [2] solids from human waste and other sources; [3] dissolved pollutants from human waste and decomposition products; and [4] dangerous microorganisms.
Methane is produced through anaerobic (without oxygen) decomposition of waste in landfills, animal digestion, decomposition of animal wastes, production and distribution of natural gas and petroleum, coal production, ...
A mineral resulting from the decomposition of a primary mineral or from the precipitation of the products of decomposition of a primary mineral. See also primary mineral.

Fossil fuel - coal, oil and natural gas. A fuel that's been made by the decomposition of fossilised plants and animals.
Along with bacteria, fungi are the principal organisms responsible for the decomposition of carbon in the biosphere.
However, even biodegradable materials will not break down once they are buried in a landfill because they are deprived of oxygen, which is necessary for decomposition. Composting provides optimal conditions for biodegradation.
An intrinsic ecosystem characteristic related to the set of conditions and processes whereby an ecosystem maintains its integrity. Ecosystem functions include such processes as decomposition, production, nutrient cycling, ...
Methane is produced naturally, including from volcanoes, wetlands, termites and the ocean, and by human activity, including from flatulent livestock and the decomposition of organic matter buried in landfill.
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 ...
