Abstract: A method for the treatment of waste materials wherein solid and/or liquid wastes are mixed with a binding material; the mixture is passed through an extruder to form pellets of waste; the pellets pass through a pyrolysis zone in a furnace or kiln to drive off at least a portion of the volatile gases in the waste, the pellets are passed through an oxidation zone in the furnace or kiln where the excess oxygen causes the remaining volatile gases and at least a portion of the fixed carbon in the waste to be oxidized and the pellets are passed through a vitrification zone in the furnace or kiln to vitrify the silicates present in the pellets to form a solid aggregate.
