What is incineration waste disposal?
Incineration is the high-temperature burning (rapid oxidation) of a waste. It is also known as controlled–flame combustion or calcination and is a technology that destroys organic constituents in waste materials. New techniques are developed for this burning process, used as energy-generating methods.
What garbage is burned in the incinerator?
Incineration converts trash like paper, plastics, metals, and food scraps into bottom ash (the heavier ash residue), fly ash (the lighter, more toxic ash, that is more likely to escape the incinerator’s stack), combustion gases, air pollutants, wastewater, wastewater treatment sludge, and heat.
