Challenges of PET Trays Recycling

by Marnix van Gurp, Managing Director, Brightlands Materials Center

Although PET bottles are already reasonably well recycled, the recycling rates for PET trays are virtually zero. Among a number of different reasons why this is the case, the design of the trays plays an important role. The waste fraction of PET trays contains a considerable amount of other polymers than PET, in particular due to the lidding films which consist in many cases of multimaterial laminates.

In addition, the material used for the trays is often based on recycled bottle-PET (rPET), which has lower quality than virgin material.

The presentation will highlight these and other challenges and will propose directions to improve the recyclability of PET trays.
