Overview

kSIST-TS FprCEN/TS 18382:2026 is a technical specification developed by the Slovenian Institute for Standardization (SIST) and the European Committee for Standardization (CEN). It provides detailed guidelines for the design for recycling of rigid packaging made of biodegradable plastics. The standard aims to harmonize criteria for assessing the recycling compatibility of rigid plastic packaging-focusing on both the main body and integrated or separate components largely composed of biodegradable plastics.

Importantly, this document addresses the mechanical and chemical recycling of these plastics and does not cover aspects related to compostability or the ability of packaging to be organically recovered through composting processes.

Key Topics

• Design Compatibility with Recycling Processes

  • Defines specific design and process criteria to evaluate how rigid biodegradable plastic packaging aligns with collection, sorting, and recycling processes.
  • Considers the main body and all integrated or attached components made predominantly of biodegradable plastics.

• Categories of Design Compatibility

  • Green: Fully compatible with collection, sorting, and recycling.
  • Yellow: Limited compatibility.
  • Red: Not compatible or disruptive to recycling streams.

• Materials in Scope

  • Biodegradable plastics such as polylactic acid (PLA), polyhydroxyalkanoate (PHA), polybutylene succinate (PBS), and blends or co-polymers.
  • Excludes evaluation of compostability, focusing strictly on recyclability within established and emerging European recycling systems.

• Design Guidelines and Best Practices

  • Encourages the use of single-type biodegradable polymers when possible.
  • Advises on the minimization of adhesives and labels, ensuring components can be easily removed and are recycling-compatible.
  • Recommends colorants, fillers, and additives that do not hinder Near Infrared (NIR) sorting or recycling processes.
  • Encourages design facilitating thorough package emptying to reduce residue before recycling.

• Sortability Considerations

  • Packaging should be designed to allow effective sorting in existing and future recycling facilities, particularly addressing NIR detection compatibility.

European foreword
This document (FprCEN/TS 18382:2026) 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 Vote on TS.

Introduction
Biodegradable plastics are polymeric materials with the special intrinsic property that is determined by
the composition and structure of a material allowing them to biodegrade under specific environmental
conditions. Biodegradability of polymeric materials is determined by the chemical structure responsible
for functional group stability, reactivity, hydrophilicity and swelling behaviour. The rate and extent of
biodegradation depend on the polymer’s chemical composition, crystallinity, molecular weight, and
environmental parameters such as temperature, moisture, pH, and microbial community composition.
From this perspective, biodegradable plastics are very different from other plastics in that they have
several end-of-life options and should not be treated together with the general group. While
compostability was in the focus for many years, biodegradable plastics are also recyclable as was proven
in numerous studies.
This is especially true for the biodegradable polyesters like PLA, PBAT, PHA, PBS and the like, which
behave similar to PET. However, separate sorting and recycling at scale is still to be still built up and
recycling technologies are not mature yet. Therefore, this Technical Specification (TS) is based on the
best available knowledge and expertise at the time of drafting, including experience from companies
currently engaged in biodegradable plastics recycling and from ongoing European projects related to the
scale up of sorting and recycling procedures for these materials and from other plastics. This document
provides guidance based on current technological capabilities and does not represent state-of-
the-art collection, sorting and recycling as defined in EN 18120. As technical developments progress
and further consensus is achieved the content of this Technical Specification may be subject to
modification, review and revision.
The objective of this TS is to facilitate consistent design for recycling criteria for rigid packaging made
from biodegradable plastics, ensuring that when technologies mature and/or are brought to a larger
scale, these specifications can be smoothly incorporated into the broader standard framework.
This technical specification (TS) intends to follow the philosophy of EN 18120. Given the early market
implementation in Europe of packaging made from biodegradable plastics and the low volumes of such
packaging currently in the waste streams, existing material recycling technologies for packaging waste
made from biodegradable plastics (with levels of maturity varying depending on the polymer type) do
not currently fit into the “state-of-the-art” definition as set in EN 18120. Therefore, these TS are proposed
outside the scope of EN 18120 at this stage, while maintaining its philosophy and structure as closely as
possible. EN 18120 aims via series of guidelines and protocols to establish consistency and improvement
for the Design for recycling for household, industrial and commercial plastic packaging products.
Design for recycling guidelines are a common way of describing compatibility with plastic packaging
collection, sorting and recycling into recycled plastic. They provide guidance on the level compatibility,
defined as:
— Green: Packaging constituents with full compatibility with collection, sorting and recycling;
— Yellow: Packaging constituents with limited compatibility with collection, sorting and recycling;
— Red: Packaging constituents which are not compatible with collection, sorting and recycling.
These categories reflect compatibility under current technological conditions and do not represent state-
of-the-art recycling performance as defined in EN 18120. 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 documents are representative of the
European market and cover all steps from design for recycling, packaging waste collection, sorting,
recycling into recycled plastic and to use in a new application. Compliance with the design guidelines
does not guarantee that the recycled plastic quality will be fit for purpose for a specific targeted end
application or compliant with applicable regulations.
Packaging recyclability is the combination of design for recycling, proven collection, sorting, and
recycling.

4 Compatibility of biodegradable rigid plastic packaging designs with recycling
4.1 General characteristics
Generic aspects for design compatibility with recycling are covered in EN 18120-1.
To determine the recyclability of the design of a biodegradable rigid plastic packaging, the following
guidance tables shall be consulted in conjunction with the definitions provided in EN 18120-1. The tables
provide combined design guidance for all considered material recycling processes. This document
considers mechanical and chemical recycling of rigid packaging made of biodegradable plastics as
recycling technologies. It considers the outlets described in Table 1.
Table 1 — Outlets for recyclates considered in this document
Packaging type Recycling technology Outlet
Rigid packaging made Mechanical and chemical recycling Chemical Recycling: recycled PLA
predominantly from PLA for any application including
packaging
Mechanical Recycling: recycled PLA
for any injection moulded
application including packaging
Rigid packaging made predominantly Mechanical recycling Sheet extrusion, injection moulding,
from PHA for packaging or other applications
where the quality of the recycled
material is retained, where feasible
Rigid packaging made predominantly Mechanical recycling Injection moulding for packaging or
from PBS (Co-)polyesters other applications where the quality
of the recycled material is retained,
where feasible
These current recycling technologies for packaging made from biodegradable plastics, for post-consumer
packaging, are not yet able to conform to the “state-of-the-art” definition in EN 18120. For post-industrial recycling,
however, some technologies already conform to such “state-of-the-art” definition.
The design guidance provided in this document covers:
a) main packaging components which constitute biodegradable rigid plastic packaging, with all their
integrated components and all constituents, including those which are removed during the recycling
process and
b) separate components (of other types of packaging) which are predominantly made from
biodegradable rigid plastic materials, with all their constituents, including those which are removed
during the recycling process.
It does not apply to other types of separate components (which are already separated before and during
the sorting process) as per the definition in EN 18120-1 and as determined in EN 18120-3.
Separate components are to be evaluated separately, as described in EN 18120-1. As such, a separate
component of rigid packaging predominantly made of biodegradable plastics can be fully compatible with
recycling even when an integrated component or a constituent of the same specification would only have
limited or no compatibility with recycling according to the guidance in this document. Equally, separate
components of rigid packaging predominantly made of biodegradable plastics can be incompatible with
recycling even when an integrated component would be compatible.
The following general principles shall be followed when designing rigid packaging made of biodegradable
plastics:
— prefer natural colour packaging where possible, mainly in the main component of the packaging;
— minimize the adhesives used for bonding the different elements of the packaging and ensure they are
easily removable and are compatible with the recycling processes;
— prefer the use of a single polymer type unless additional materials are strictly necessary for technical
reasons; e.g. to avoid product waste (the guidance in the tables of this document shall apply to the
additional materials);
— minimize labels; When unavoidable, prefer the use of easily removable labels;
— design the packaging, where possible and taking into account the filling good, in such a way that it
eases emptying of its content to minimize residual content;
— if the package needs additives or barrier layers, make sure they do not contaminate and/or disrupt
recycling for the intended recycling process and use targeted by the design guidelines.
4.2 Sortability
The design guidance provided by this standard considers effects on the sortability of packaging. It does
however not provide details on established sorting processes or a method for determining sortability.
Where sortability testing is advised in the guidance of this document, the provisions of EN 18120-3 shall
apply. This includes the consideration of the effect of residual product content after emptying on the
sortability.
4.3 Biodegradable rigid plastic packaging
The biodegradable plastic packaging covered in this document is designed to be compatible with waste
collection, sorting, and material recycling processes and it is not intended to undergo a biodegradation at
its end-of-life. Therefore, biodegradable plastic packaging is not a classification based on a specific end-
2)
of-life, but rather on an intrinsic property (inherent biodegradability as per EN 13432:2000 related to
the chemical composition of a plastic material.
The main biodegradable plastics used for packaging production are largely based on polyesters and their
blends with other biodegradable materials (PLA, PHA, PBS, starch-based compounds, PCL, etc.).
4.4 Design guidelines summary table
The design guidelines in the following tables have been established reflecting collection, sorting and
recycling in Europe.
All the below design guidelines have been developed with the objective to be able to produce recyclates
that can be used in the applications indicated in Table 1 of this TS. The process used to produce the
recyclates is also indicated in Table 1 of this document.
The following tables shall be used for the design-for-recycling criteria for rigid packaging made of
biodegradable plastics, with the following specific considerations:
— for rigid packaging made predominantly from PLA, refer to Table 2;
— for rigid packaging made predominantly from PHA, refer to Table 3;
— for rigid packaging made predominantly from PBS, refer to Table 4.
All values using "%" as unit in the Tables 2, 3 and 4 refer to mass fractions of intentionally added
substances and constituents, unless explicitly stated differently.

Biodegradable plastic in the context of this document is characterized only by its inherent biodegradability as per
EN 13432:2000 (and not by other requirements of EN 13432:2000).
