European foreword
This document (prEN 18120-10:2024) has been prepared by Technical Committee CEN/TC 261
“Packaging”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
Introduction
EN 13820 consisting of 15 parts aims via a series of guidelines and protocols to establish consistency and
improvement for the Design for recycling of household, industrial and commercial plastic packaging.
— Part 1: Definitions and principles for design-for-recycling of plastic packaging
— Part 2: Process and governance to evaluate the recyclability of plastic packaging
— Part 3: Sorting evaluation process for plastic packaging
— Part 4: Guideline and protocols for PET bottles
— Part 5: Guideline and protocols for PET other rigid packaging
— Part 6: Guideline and protocols for PE and PP rigid packaging
— Part 7: Guideline and protocols for PE and PP flexible packaging
— Part 8: Guideline and protocols for PS packaging
— Part 9: Guideline and protocols for EPS packaging

— Part 15: Recyclability evaluation process for plastic packaging — Protocols for EPS packaging
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 provides requirements for the evaluation process for PET Bottles with
respect to compatibility of the design with recycling processes.
Packaging components and ancillary elements made of other materials than PET are also covered by this
document as they need to be evaluated for compatibility with the recycling processes.

4 Recyclability evaluation process
4.1 Principle
4.1.1 General
This document provides a method of evaluating the technical recyclability of a PET Bottle 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 Bottle 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 bottles 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 article
