Trade body Plastics Recyclers Europe has called for PET trays to have their own recycling stream.
It wants these valuable products to be sorted separately from the PET bottle stream and recycled separately in order to ensure resource efficiency.
Plastics Recyclers Europe PET chairman Casper van den Dungen said: “Trays and bottles are two different types of products which cannot be recycled in the same recycling line.
“Their designs and chemical compositions are not the same and can create quality problems for existing PET recyclers.
“The collection schemes and sorting centres cannot push this issue down the value chain.”
Plastics Recyclers Europe wants a joint value chain approach to recycling the 700,000 tonnes of PET trays consumed each year in Europe.
