Abstract
A plant for treating industrial and/or urban waste includes a stage for drying of the waste, followed by a stage for effecting thermolysis of the dried waste and a stage for effecting recovery of the solids and gases resulting from the thermolysis. Thermolysis of the waste is effected in a reactor by indirect heat exchange with combustion gases and drying gases for drying of the waste are subsequently treated to remove vapor materials and then recycled to a gas generator for generating the drying gases. Additionally the plant includes a stage for effecting dechlorination of the solids resulting from the thermolysis by washing the solids with an aqueous liquid, as well as a stage of separating the wash solids and the resulting wash liquid.
