Extrusion and melt degassing
For the bottle-to-bottle PET recycling process, we have developed extrusion and degassing concepts with multiple or single shaft extruders are used. Our process concepts can be individually optimized to obtain clean recycling material according to the specific requirements and legal regulations of the food industry.
Thanks to many years of experience, POLYMETRIX is able to integrate extrusion concepts from different manufacturers into the recycling process.
