The European Union has encouraged and acted on the need for circular packaging by implementing many initiatives, including mandating legislation in order to achieve an ambitious target of 25% rPET being utilized in PET packaging by the year 2025, and then scaling this figure up to 30% for the overall plastic packaging industry by 2030.1 With 47% of PET demand in Europe used to produce bottles,2 it is no surprise PET has long been at the center of this green revolution. Avient undertook a recyclability study to show how bottles containing 0.09% Fortis Amber-1 and 4% Amosorb SolO2-2 achieve optimal results when going through two full loops of recycling. Bottle A is the original bottle with 100% virgin material and a combination of Amosorb SolO2-2 at 4% with Fortis Amber-1 at 0.09% LDR.
