<p>Recovery of plastics comprises peeling multilayered plastics into individual layers of plastics by shearing, impact, tearing, etc. while heating the plastics. In an example, a blow-moulded article of a double-layered structure comprising a polyamide resin outer layer and low-density polyethylene inner layer was heated at 140 degrees C in an oven, and crushed instantaneously in a rotary shear crusher. The polyamide and low density polyethylene were classified by hand. A sepn. rate of ca. 100% was achieved.</p> |
