Abstract: An apparatus for treatment of rubber and plastic wastes, comprising in series an extruder for heating and melting rubber and plastic wastes to extrude the molten wastes, a decomposing section for heating the molten wastes to prepare decomposed products while optionally separating residues therefrom, a dry-distilling section for gasifying the decomposed products by dry-distillation, and a cooling section for cooling the dry-distilled products to separate gaseous materials from liquid materials.

Abstract: A method for the treatment of rubber and plastic wastes, comprising in series the steps of1. heating and melting rubber and plastic wastes at a temperature (T.sub.1) to extrude the molten wastes with one or a plurality of extruders into one or a plurality of decomposing zones,2. heating the molten wastes in the decomposing zone at a higher temperature (T.sub.2) than the heating temperature (T.sub.1) in the extruder to prepare decomposed products while optionally separating residues therefrom,3. introducing the decomposed products into a dry-distilling zone while optionally heating the separated residues in a residue removal zone at an even higher temperature (T.sub.3) than the heating temperature (T.sub.2) in the decomposing zone to remove the residues from the residue removal zone when residues are separated in the decomposing zone,4. heating the decomposed products in the dry-distilling zone at a lower temperature (T.sub.4) than the heating temperature (T.sub.
