Abstract

PURPOSE:To dispose plastic wates safely free from fear of scattering even when asbestos wastes stick to bags made of plastics, by feeding the bags made of plastic into an extruder having a heating zone only at the tip to remove the raw material adhered, and by melting only the surfaces of the bags under heating.
