Bottle-to-bottle recycling and tray-to-tray recycling is recycling in the true sense of circularity. Our solutions for recycling of post-consumer recycled PET are solid-state polycondensation (SSP) plants, super-cleaning and crystallization units for iV increase and decontamination of polyester pellets and/or flakes. They are used for pre-treatment of recycled material for premium sheet production or post-treatment of resins for food-grade packaging of food and beverages.
