Waste-to-energy (WTE) technologies for municipal solid waste (MSW) trace back to waste incineration, a practice used for centuries to sterilize and reduce the volume of unwanted material to be disposed of. Incineration basically consists in the combustion of waste in air, a physico-chemical process where most of the waste mass is oxidized and converted into flue gas. The heat generated by oxidation brings the waste to high temperature, so that waste is sterilized. The operation at relatively high temperatures justifies the term thermal treatment. Nonvolatile components remain as solid residues called ashes; they feature a volume 80%-90% lower than that of fresh waste, and are not subject to putrefaction.

Abstract
Waste-to-energy (WTE) technologies for municipal solid waste (MSW) trace back to waste incineration, a practice used for centuries to sterilize and reduce the volume of unwanted material to be disposed of. Incineration basically consists in the combustion of waste in air, a physico-chemical process where most of the waste mass is oxidized and converted into flue gas. The heat generated by oxidation brings the waste to high temperature, so that waste is sterilized. The operation at relatively high temperatures justifies the term thermal treatment. Nonvolatile components remain as solid residues called ashes; they feature a volume 80%-90% lower than that of fresh waste, and are not subject to putrefaction.| File | Dimensione | Formato | |
