Abstract (en)
[origin: WO2019202546A1] Plastic material (4) is moved to the reactor's (2) vessel through feeder (1) in a pre-heated and compressed state at temperature at least 150°C. The plastic material (4) is during the depolymerization running in the reactor's (2) vessel led to the vessel continuously with a volume or mass flow which is regulated in order to achieve a stable level and/or stable mass amount of the material (5) in the reactor's (2) vessel. The plastic material (4) in the reactor's (2) vessel depolymerizes without the access of air and without catalyst during at least partial mixing at temperature ranging from 200°C to 500°C. The feeder (1) can have a form of the screw extruder with a heated casing and adjustable screw rotations, whereby it has a transport zone (11), a compression zone (12), a homogenizing zone (13) and suction (9). The flow of the plastic material (4) on the feeder's (1) outlet per minute is less than 5% of the volume or 5% of the mass of the material (5) in the reactor (2).
