A waste treatment technology, which includes the combustion of waste for recovering energy, is called
as “incineration”. Incineration coupled with high temperature waste treatments are recognized as
thermal treatments. During the process of incineration, the waste material that is treated is converted in
to IBM, gases, particles and heat. These products are later used for generation of electricity. The gases,
flue gases are first treated for eradication of pollutants before going in to atmosphere.
Among waste-to-energy technologies, incineration stands taller. Other technologies are gasification,
PDG, anaerobic digestion and Pyrolysis. Some times Incineration is conducted with out the reason for
recovering energy.
In past, incineration was conducted with out separating materials thus causing harm to environment.
This un-separated waste was not free from bulky and recyclable materials, even. This resulted in risk for
plant workers health and environment. Most of such plants and incinerations never generate electricity.
Incineration reduces the mass of the waste from 95 to 96 percent. This reduction depends upon the
recovery degree and composition of materials. This means that incineration however, does not replace
the need for landfilling but it reduced the amount to be thrown in it.
Incineration comes with a number of benefits in specific areas like medical wastes and other life risking
waste. In this process, toxins are destroyed when waste is treated with high temperature.
Incineration or thermal treatment of waste is much popular in countries like Japan where there is scarcity
of land. The energy generated by incineration is highly demanded in countries like Denmark and
Sweden. In year, 2005 it was estimated that 4.8 percent of the electricity as is consumed by Danish
nation was produced by incineration and the amount of heat was some 13.7 percent out of total. Other
then Denmark and Sweden many European countries are recovering heat and electricity from waste.
