Detoxified hazardous wastes include combustible carcinogens, mutagens, teratogens, and pathological wastes. Another advantage of incineration is the reduction of leachable wastes from landfills. Incineration of contaminated soils is increasing. The EPA, for example, employed a mobile incinerator to decontaminate 40 tn of Missouri soil that was contaminated with 4 lb of dioxin compounds.

Different incineration technologies are used to handle various types of hazardous waste. The four most common incinerator designs are liquid injection (sometimes combined with fume incineration), rotary kiln, fixed hearth and fluidized bed incinerators.

The four major subsystems of hazardous waste incineration are: (1) waste preparation and feeding, (2) combustion chamber(s), (3) air pollution control, and (4) residue and ash handling. The normal orientation of these subsystems is shown in Figure 11.14.1, along with typical process component options.
