Device and method for recycling post-consumer plastic waste shredded to flakes and washed

A device for recycling flakes from shredded and washed post-consumer plastic waste, comprising:

• a pre-treatment unit for drying and homogenising the flakes from shredded and washed post-consumer plastic waste,
• a melting extruder arranged downstream of the pre-treatment unit for melting the plastic waste dried and homogenized in the pre-treatment unit,
• a degassing extruder arranged downstream of the melting extruder for degassing the plastic melt,
• optionally a melt filter arranged between the melting extruder and the degassing extruder for removing foreign matter from the plastic melt,
• a granulating device arranged downstream of the degassing extruder for granulating the plastic melt,
• a post-treatment unit arranged downstream of the granulating device,
• and optionally a drying device arranged between the granulating device and the post-treatment unit for drying the granules,
• characterised in that
• at a plastic melt path comprising the melting extruder, the degassing extruder, optionally the melt filter as well as the connecting lines therebetween, there are provided at least one process gas feed and at least one gas discharge for discharging an exhaust gas stream, wherein the at least one process gas feed is connected to an ozone source or an ozone generating device, whereby ozone-enriched process gas may be supplied to the plastic melt path, wherein a process gas feed is connected to the melting extruder and a gas discharge is connected to the degassing extruder.
