Incineration Guide, Meaning , Facts, Information and Description
Incineration is the process of destroying something unwanted through fire. Incineration is carried out both on a small scale by individuals, and on a large scale by industry. Material can be simply burned while sitting on the ground or in a pit, although specialized devices and structures have been developed. Operation of incinerators for waste management is controversial for several reasons: both the gases and the ash residue may be toxic. Their use is frequently restricted by law due to the resulting air pollution.Incinerators (particularly large ones) can be used for generating electricity or provide energy in other ways such as generating steam for heat. Such a use is known as waste to energy. However, a significant amount of energy is lost due to "scrubbers", and other methods used to clean up the exhaust. The leftover ash is often sent to a landfill.
The use of incinerators has been on the decline in the United States. There were 98 such plants in 2002 and 89 in 2004. It is often cheaper to take waste directly to a landfill, so plants sometimes end up being subsidized in order to compete. A process that may end up supplanting incineration (if proved to be efficient) is thermal depolymerization.
Incinerated human corpses are said to be cremated.
The ancient Hebrews burned their waste in a pit called Gehenna.
