Abstract

For many years, PET up-cycling technology was dominated by solid state polycondensation which is an established solution to harmonize material properties across different flake feed-stocks, lifting IV values, and reducing volatile contaminants.

Next Generation Recycling Machines has developed new technology based on Liquid State Polycondensation. This process delivers more reliable and faster IV lift, reduces contaminants with much higher efficiency and expands the possibilities bringing PET feedstock back into valuable applications. The implementation of this technology is called P:REACT and consists of a vacuum reactor that accepts devolatized PET melt from an extruder. Within just 20-25 minutes of residence time, P:REACT delivers IV lifted and decontaminated melt to a downstream die. The process is continuous, completely automated and in most cases, the PET scrap can be received by the extruder without pre-drying. IV lift of 15-25% is possible depending on the input material. Output melt from the P:REACT is FDA approved for 100% food contact.

In this presentation, Schneider will discuss the technology, the achieved results, and typical applications in bottle-to-fiber, bottle-to-sheet, and bottle-to-bottle.
