  • Method and device for processing plastic waste, especially polyolefins
    Patent number: 9006505
    Abstract: A method for processing plastic waste, in particular polyolefins, and a device for processing plastic waste, in particular polyolefins, are used especially in the industrial utilization of plastic waste. The method consists in that a primarily refined charge after being fed into a reactor (6) is fluidized and cracked during forced progressive-rotational movement coinciding with heating. A gas-steam fraction obtained during a utilization process is continuously guided out to a cooling system whereas impurities are periodically guided out from the reactor (6) to a waste tank (22).
