Wastes incineration, such as household, industrial or hospital wastes, produce flue gases containing a wide range of pollutants. Most of them can be collected through conventional processes such as bag filters, electro-filters, and scrubbers.However, dioxins and heavy metals such as mercury and cadmium can not be treated without a reagent injection such as Powdered Activated Carbon (PAC) or lignit coke which catalyze and reduce the pollutants content to range within the legal level of emissions.
