VERFAHREN ZUR HERSTELLUNG VON GRANULIERTEM ABFALLKUNSTSTOFF UND VERFAHREN ZUR THERMISCHEN ZERSETZUNG DES KUNSTSTOFFS

摘要

The present invention provides a method for improving the apparent density and quality of shape of granules produced by compression molding waste plastics and a method for economic thermal decomposition of waste plastic granules for recycling as a chemical feedstock, comprised of crushing waste plastics containing at least 15 mass% of film-shaped plastics by a crusher 1 so as to produce plastic pieces of a size suitable for compression molding, then producing cylindrical granules by a compression molding machine 4 having extrusion holes of a diameter of 5 to 80 mm. Further, the waste plastic granules are thermally decomposed and recycled for chemical feedstock etc. Further, they are thermally decomposed in a coke oven, blast furnace, etc. for recycling.
