Design for recycling guidelines are a common way of describing compatibility with plastic packaging
collection, sorting and recycling into high quality recycled plastic into state-of-the-art facilities. They
provide guidance on the level compatibility, defined as:
— green: Packaging constituents with full compatibility with recycling;
— yellow: Packaging constituents with limited compatibility with recycling;
— red: Packaging constituents which are not compatible with recycling.
Recyclability guidelines will require regular review and improvement to reflect innovations in design,
collection, sorting and recycling.
The Design for recycling guidelines provided in this series of standards are representative of the state of
the art in Europe and cover all steps from design for recycling, packaging waste collection, sorting,
recycling into recycled plastic and to use in a new application.
Packaging recyclability is the combination of two parameters: packaging designed for recycling and the
existence of a recycling stream. Design for recycling guidelines act as a first indicator.
1 Scope
This document covers the design of PET pots and trays with respect to compatibility of the design with
recycling processes.
Packaging constituents and packaging components made of other materials than PET are also covered by
this document as they need to be evaluated on compatibility with polymer recycling.

4 Recyclability evaluation process
4.1 Principle
This standard provides a method of evaluating the technical recyclability of a PET rigid packaging (except
bottles) sample in mechanical recycling processes as they are implemented in Europe. The results
characterize both the processability of the sample as well as the quality of the recycled plastic.
Depending on the choice of the sample, the method can either provide a technical recyclability
determination for a given packaging design or item, or it can be employed to selectively study the impact
of individual design elements of a PET rigid packaging on technical recyclability.
The latter approach may be employed to generate data for the updating of design-for-recycling
guidelines.
The test method follows the steps (unit operations) that occur in a mechanical recycling process for PET
rigid packaging (mainly thermoforms) and seeks to simulate each operation on a laboratory scale.
The relevant unit operations are shown in Table 1. Steps 0 to 5 describe the plastic recycling process itself
whereas step 6 represent the conversion of the recycled PET into articles, in this case plaques is preferred
because it offers greater repeatability at laboratory scale than the sheet extrusion.
As such, steps 0 to 4 provide information on the processabilit
