Setting a New Standard in Food-Grade PET RecyclingMAS introduces the iQonicTwin HyperPET, an innovative platform for
PET recycling designed to meet the highest standards for food-contact applications while unlocking new business opportunities. The flagship HyperPET solution integrates MAS’s proven co-rotating conical twin-screw extruder with a Solid-State Polycondensation (SSP) process based on infrared radiation and vacuum, eliminating the need for nitrogen, to deliver exceptional intrinsic viscosity (IV), color stability, and minimal acetaldehyde (AA) formation at reduced energy consumption.
MAS is partnering with PET recycling specialist Christian Schiavolin to integrate his proven solution into the innovative MAS iQ Series. Through the iQonicTwin HyperPET solution, MAS is working closely with him to solidify further its position as a leading provider of comprehensive plastics recycling and upcycling services.
iQonicTwin HyperPET: Pre-Extrusion SSP
In the HyperPET configuration, polycondensation occurs upstream of extrusion:
1. RPET flakes are pre-heated and dried in a crystallizer.
2. The MOBY reactor applies infrared radiation under vacuum, reducing moisture and adjusting IV to the target level for bottle-grade applications.
3. Stored heat reduces extrusion energy needs and increases throughput.
While traditional food-grade PET recycling relies on “bottle-to-bottle” processes, HyperPET extends capabilities to future “tray-to-bottle” recycling. This allows for the processing of both bottle and PET tray regrind, either alone or blended, thereby expanding the feedstock pool and reducing reliance on post-consumer bottles.
Operational and Economic Benefits
The MAS iQ HyperPET solution offers:
• Stable, high-quality pellets with consistent IV, color, and low AA
• Compliance with the strictest food-contact regulations
• Reduced OPEX thanks to energy savings and operational simplification
• Greater sourcing flexibility, improving ROI
Flexible Capacities
iQonicTwin HyperPET is available in three capacities, making it suitable for both pilot lines and industrial-scale applications.
MAS also now offers a rPET SSP solution and a rPET Regran solution, which are part of the new innovative MAS portfolio.
