NGR
The future of PET recycling
The P:REACT transforms PET waste and bottle flakes into food-grade recycled PET in minutes using Liquid State Polycondensation (LSP) technology — FDA and EFSA approved for 100% food-contact safety.

The LSP-Process utilizes the inherent capability of PET to condensate in the molten phase under vacuum. This condensation leads to an increase of IV. The high performance vacuum effectively decontaminates the material from harmful chemicals, – securing further use of the material for 100% food contact.
As molten PET enters the vertical part of P:REACT, strands are formed to create a suitable surface to volume ratio. The material is then collected in a horizontal drum and slowly pushed forward. Condensation starts immediately as the strands are formed and is set forth until PET exits P:REACT. IV increase is controlled by the residue time and the vacuum level of the molten PET inside P:REACT and therefore can be adjusted to a desired level. The settings of parameters allow the control unit to maintain the desired IV-level within a small tolerance-band.
The decontamination performance is extremely effective, as carried out in the liquid phase of PET. The cleaning of the material exceeds limits set by recognized food safety standards, but also effectively removes spin oil from fibers.
Approved for 100% food-contact safety, with effective decontamination of harmful chemicals and spin oils during the melt phase.
Intrinsic-viscosity values are controlled precisely — potentially exceeding original material quality — rising ~0.01 dl/g per minute with automatic level control.
Exceptional continuous operation with inline IV measurement for reproducibility and traceability within a narrow tolerance band.
Colour changes are possible during continuous operation without shutdowns, minimising downtime and fibre breaks.
Consistent output quality across varied feedstock reduces the need to add virgin PET.

For low-viscosity melts. The melt emerges from strand nozzles, is cooled in a water bath, dried by means of a fan and cut to the desired length in the pelletizer. The result is cylindrical, dust-free pellets with excellent mixing properties.
In addition to the benefits of the SP, the A-SP option offers the added convenience of fully automated start-up. The strands are transported automatically by a water slide to the pelletizer, and the pellets are dried in a centrifuge.
For difficult-to-process (e.g. sticky) polymers or thermoplastics with a very high melt flow index. The melt emerges from the die plate and is knocked off by the pelletizer blades. The whole process takes place under water. In the centrifuge, the pellets are separated from the process water and dried.
For heavily contaminated materials. The hydraulically operated double-piston screen changer filters the melt in a process-controlled and continuous manner. The integrated backwash device automatically cleans the screens. The number of back-flushes and the related service life of the screens depend on the degree of contamination of the material.
For heavily contaminated materials. In contrast to the standard backflush screen changer with 2 screen cavities, this system is equipped with 4 screen cavities. The double filtration surface with the same frame size results in a longer filter life.
The continuous melt filters in the ERF series are suitable for a wide range of moderate and highly contaminated polymers and provides a pressure constant operation, long screen lifes, very low melt losses and a compact design. By the permanently rotating filter drum foreign particles are being constantly and effectively removed, depending on the application ERF melt filters enables throughputs from 150 to 10,000 kg/h.
The throughput scale is integrated in the machine control system and displays the current production output in kg/h (lbs/hr). The data can be logged in a BDE system.
For continuous melt viscosity measurement. Melt is taken from the production extruder, the viscosity is measured, and then the melt is returned to the extruder. Based on the differential pressure across the capillary, the viscosity of the material (IV value, MVR) is determined by means of a stored recipe.
