Burning waste also pollutes people and the environment. Mercury, dioxins, lead, and other pollutants come from burning waste. In terms of climate impacts, incinerators emit more carbon dioxide
answer:-
Incineration
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.
