ABSTRACT OF THE DISCLOSURE High polymer waste products fill the garbage dumping grounds or they are only insufficiently converted into new low-quality products by means of imperfect recycling processes. The novel process according to the present invention will make it possible to process high polymer, preferably those which contain no volatile matter that can be defined by standardized measuring methods independently of their chemical composition and physical consistency in a form such that the raw material substance contained therein is completely reusable. The polymer waste products are converted into a crushed or granulated form and into a conveyable consistency by mixing them with superheated steam and by feeding them to a hydrogen plasma jet having an average mass temperature of at least 1000°C and a pressure of 0.05 to 0.5 MPa so that the polymer suspension or granulate is mixed with the hydrogen plasma. In this hydrogen plasma the polymer waste products are completely decomposed and are reacted to highly endothermic valuable target products, such as acetylene, ethylene, hydrogen, CO, HCN or HCl. The aim is the complete material reprocessing and high finish of all the high polymers made available by the chemical industry, i.e., those having passed through one or several utilization processes.
