Zusammenfassung:	Chemical recycling method for polyester based textile and/or packaging waste. In the method, colorless bis hydroxyethyl terephthalate (BHET) is obtained from packaging waste containing polyester and/or textile produced from at least 50% polyester, having at most 50,000 ppm coloring agent or filler material, to be used in the production of packaging materials and/or textile materials such as yarns based on recycled colorless polyethylene terephthalate (PET), fabric, nonwoven (nonwoven fabric). The method also enables the re-production of PET from the BHET.
