Effect of poly lactic acid trays on the optical and thermal properties of recycled poly (ethylene terephthalate)

To progress towards a more sustainable plastic system, multiple interventions are required, including the decoupling from fossil feedstock. Biobased plastics therefore have to be integrated in waste management systems. This should, however, not hamper performance of current recycling Several studies previously suggested that uptake poly lactic acid (PLA) this system would endanger (ethylene terephthalate) (PET) recycling. study reports estimated concentration PLA recycled PET and effect presence impurity on optical thermal properties PET. The concentrations Netherlands were modelled vary between 0% 0.019%. When consumption rises, can kept below 1% with NIR technologies. impact 0.1 was negligible. Conversely, negative 0.1% PVC substantial. Also EVOH studied like found limited. contravenes previous quality difference is within study, has been processed agreement industrial methods. Therefore, case sorting facilities maintain their careful operation, no foreseen, further integration biobased pursued.
