PET-G as a PET contaminant
Original language description
Currently, PET recycling companies are increasingly confronted with a new type of contaminant such as PET-G, which was introduced as an alternative to PVC. The group of copolymers referred to as "PET-G" is extensive and contains more than 60 modifications. These differ in the molar ratios of the individual components of the copolymer, which fundamentally affect the physical properties. The final products are commonly referred to as "PET". PET-G is therefore often perceived as another type of PET. Although PET and PET-G are physiochemically similar, the most crucial is the difference in their melting point. In some countries, PET-G has therefore been excluded from recycling category 1 (PET) and classified in category 7 (other plastics). Opponents of this reclassification argue that it is sufficient to adjust the sensitivity of sorting devices with NIR detectors. In our analysis several dozen samples, which the recycler identified as contaminants, were examined in order to detect the presence of PET-G.
