This paper deals with an advanced procedure and plant for the recovery of useful products (toluene and metallic copper) from organic catalyst hazardous waste, based on copper tetrachloroaluminate dissolved in an alkyl benzene type of solvent, used for the selective separation of carbon monoxide resulted during hydrocarbon combustion. At the same time, a new inorganic composite coagulant made of a mixture of iron chloride and aluminium chloride is obtained. The procedure is the object of a
