European foreword
This document (prEN 18120-14:2024) 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.

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 five parameters: packaging designed for recycling,
packaging waste collection, sorting when necessary, recycling and use of recycled plastic in a new
application. This series of standards covers one parameter: the design for recycling.
1 Scope
This document covers recyclability evaluation process guidance for PS and XPS packaging with respect
to compatibility of the design with recycling processes for the polymers used.

4 Recyclability evaluation process
4.1 Principle
This standard provides a method of evaluating the technical recyclability of a rigid PS or XPS packaging
sample in mechanical or chemical 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 in PS or XPS plastic 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 recycling process for rigid PS or XPS
packaging and seeks to simulate each operation on a laboratory scale. If one or more operational unit
item is tested leveraging a pilot line or an industrial line this is also permitted as long as the operation
tested is representative to the state-of-the-art technologies as described in prEN 18120-1.
4.2 Applicable unit operations
Step # Unit operation High level process description Reference test
procedures
0 Control material For the purposes of this standard, at least 25 kg /
selection of a suitable control material is required. The
control material can be selected from:
Option 1: An item made from a PS resin or resin
blend. The chosen resin or resin blend shall be
extruded and converted in rigid items at
conditions resembling commercial practices to
obtain the control material.
Option 2: A PS item which is known to be
recyclable and consisting of the same base PS
resin or resin blend as the test sample.
