Sludge incineration has been used in Japan for the last 30 years, as a method to reduce the sludge volume and to destroy organic pollutants. Today, incineration is conducted mainly in conventional fluid bed incinerators, however there is a shift towards the use of circulating fluid bed incinerators instead. The occurrence of dioxins is very […]
