Incinerator Waste

Incinerator waste is a broad term for residues that result primarily from controlled incineration activities in large-scale facilities. Incineration is considered one of the most effective waste treatment operations because of high reduction and decontamination rates of physical and chemical composition of wastes. But not all substances are destroyed by the industrial furnaces, cement kilns, or other thermal installations used for incineration. Some noncombustible matters persist and are classified as residual waste streams, dealt with by sterilization, transport and landfilling actions, or recovery activities like downcycling or energy generation.

Statistics on the percentage of waste not destroyed by incineration are usually disparate, with figures anywhere between 5 and 50 percent, given distinct applied technologies, original matters, and other factors. Sizable amounts of solid components, gaseous effluents, liquid substances, and air particles remain, however, as by-products of incineration. Among these, fly and bottom ash are regularly identified as main residues, but matters like grate siftings, frequently amalgamated with fly and bottom ash, as well as slag with vitrified metals, or cleansing waters and sludges, should also be counted as wastes.
