Packaging - Requirements and test scheme for carrier bags suitable for treatment in well-managed home composting installations
This document specifies a testing scheme and requirements for the designation of carrier bags of any materials that are considered to be suitable for the incorporation into well-managed home composting installations run by householders for personal uses. Carrier bags are considered as suitable for home composting only if all the individual components meet the requirements.
The following five aspects are addressed:
a) characterization;
b) biodegradation;
c) disintegration during home composting;
d) compost quality;
e) recognizability.
The first four aspects (a) to d)) are assessing the effects on the biological treatment process and the compost made by it. The fifth aspect ensures the recognizability of home compostable carrier bags by the end user.
This document forms the basis for the labelling of carrier bags of any material that are considered to be suitable for the incorporation into well-managed home composting installations.
NOTE 1 Compliance with the requirements of this document by the carrier bags entering the compost does not necessarily imply that a high-quality compost will be produced.
This document covers the home compostability of the carrier bags themselves but does not address regulations that may exist regarding the home compostability of any residual contents.
The testing scheme and the requirements specified by this document do not apply to worm composting and/or industrial composting.
It does not provide information on the biodegradability of carrier bags ending up in the environment as litter.
This document includes a reference to guides to well-managed home composting (Annex E).
Compost produced by a private individual is for his own use and not for provision to others, free of charge or in return for payment. This document has no value as a marketing authorization or authorization of use of the final compost.
NOTE 2 The testing scheme and evaluation criteria could be the basis for the establishment of suitability to home composting of other products.
Verpackung - Anforderungen an und Prüfmethoden für heimkompostierbare Tragetaschen in einer kontrollierten Heimkompos-tieranlage
Dieses Dokument legt ein Prüfschema und Anforderungen für die Kennzeichnung von Tragetaschen aus allen Materialien fest, die als geeignet für die Zuführung in kontrollierte Heimkompostierungsanlagen für nicht gewerbliche Zwecke mit einem Heimkompostierungszyklus von üblicherweise mindestens 12 Monaten erachtet werden. Tragetaschen gelten nur dann als heimkompostierbar in einem kontrollierten System, wenn alle Einzelbestandteile den Anforderungen entsprechen.
Es werden die folgenden vier Aspekte behandelt:
a) Charakterisierung;
b) Bioabbau während der kontrollierten Heimkompostierung;
c) Desintegration während der kontrollierten Heimkompostierung; und
d) Heimkompostqualität.
Die vier Aspekte a) bis d) bewerten die Auswirkungen auf den biologischen Behandlungsprozess und den daraus erhaltenen Kompost.
Dieses Dokument bildet die Grundlage für die Kennzeichnung von Tragetaschen, die als geeignet für die Zuführung in kontrollierte Heimkompostierungsanlagen erachtet werden.
ANMERKUNG 1 Die Einhaltung der Anforderungen dieses Dokuments durch die dem Kompost zugeführten Trage¬taschen führt nicht zwingend dazu, dass ein hochwertiger Kompost hergestellt wird.
Dieses Dokument behandelt die Eignung von Tragetaschen für die Zuführung in kontrollierte Heimkompos¬tierungsanlagen, geht jedoch nicht auf Vorschriften ein, die möglicherweise für die Eignung von zusammen mit der Tragetasche entsorgten Abfällen für die Heimkompostierung gelten.
Dieses Dokument enthält eine Reihe von Leitlinien zu den Parametern, Einschränkungen und Prozessen, die für eine kontrollierte, aerobe Heimkompostierung erforderlich sind. Alternative Kompostierungsverfahren und -systeme bieten möglicherweise nicht die erforderlichen Bedingungen für eine erfolgreiche Heimkom¬postierung von Tragetaschen, die den Anforderungen dieses Dokuments entsprechen.
ANMERKUNG 2 Weitere allgemeine Informationen zur Heimkompostierung sind in Anhang F enthalten.
Das Prüfschema und die in diesem Dokument festgelegten Anforderungen gelten nicht für die Wurmkom¬postierung, die industrielle Kompostierung oder die kommunale Kompostierung. Es liefert außerdem keine Informationen über die Bioabbaubarkeit von Tragetaschen, die als Abfall in die Umwelt gelangen.
Dieses Dokument enthält Hinweise zu Merkmalen für eine kontrollierte Heimkompostierung (Anhang E).
Kompost, der durch Heimkompostierung von einer Privatperson hergestellt wird, ist nur für den privaten Gebrauch und nicht für die unentgeltliche oder kostenpflichtige Abgabe an andere bestimmt. Dieses Dokument hat daher keinen Wert als Genehmigung für das Inverkehrbringen oder die Verwendung des fertigen Komposts.
ANMERKUNG 3 Das Prüfschema und die Bewertungskriterien könnten die Grundlage für die Feststellung der Eignung zur Heimkompostierung anderer Produkte sein.
ANMERKUNG 4 Der Zweck der Prüftätigkeit b) besteht darin, das Potenzial des vollständigen Bioabbaus des Prüfmaterials nachzuweisen, wenn es unter mesophilen Bedingungen aktiven Mikroben ausgesetzt (zwischen 15 °C und 45 °C).
ANMERKUNG 5 Der Zweck der Prüfungstätigkeit c) besteht darin, die Dicke und/oder die flächenbezogene Masse zu überprüfen, die eine vollständige Desintegration des Prüfprodukts in einer Zeitspanne, die einem Zyklus der Heim¬kompostierung entspricht, unter festgelegten Umweltbedingungen ermöglicht. Um den potenziellen Schwankungen der lokalen klimatischen Bedingungen und der Anwendung von Techniken der kontrollierten Heimkompostierung durch die Verbraucher Rechnung zu tragen, wurde für diese Prüfung ein Temperaturprofil gewählt, das niedriger als das optimale ist.

Introduction
EN 13432:2000 specifies the requirements relating to packaging (including carrier bags) recovered
through organic recycling (e.g. aerobic composting) in municipal or industrial biological waste treatment
facilities. Carrier bags compliant with EN 13432:2000 are thus called “compostable” to indicate that they
are suitable for this recovery option. However, the term “composting” is also used to designate “home
composting” and this can generate confusion for the citizen.
Home composting is a practice used by private individuals to treat garden and food waste generated at
household level and produce compost for personal gardening use. Despite the common name, industrial
and home composting are two very different activities, the former being a controlled waste treatment
process and the latter being a gardening activity.
Home composting is affected by the feeding regime (usually discontinuous in quality, quantity, and
intervals), by the composting style of the householder (accurate or careless), and by the local climatic
conditions. The small dimensions of composting installations usually do not allow the generation of heat
enough to sustain high temperatures.
As a result, conditions in home composting can be very different from conditions in industrial
composting. As a result of this, a carrier bag recognized as “compostable” according to EN 13432:2000
cannot automatically be considered as suitable for treatment in a well-managed home composting
installation (see 3.5 and Informative Annexes E and F).
This document has been prepared in order to define the necessary characteristics of carrier bags for
displaying biodegradation and disintegration behaviour compatible with well-managed home
composting installations.

1 Scope
This document specifies a testing scheme and requirements for the designation of carrier bags of any
materials that are considered to be suitable for incorporation into well-managed home composting
installations for non-commercial purposes with a home composting cycle of normally at least 12 months.
Carrier bags are considered as home compostable in a well-managed system only if all the individual
components meet the requirements.
The following four aspects are addressed:
a) characterization;
b) biodegradation in well managed home composting;
c) disintegration in well managed home composting; and
d) home compost quality.
The four aspects, a) to d), are assessing the effects on the biological treatment process and the compost
made by it.
This document forms the basis for the labelling of carrier bags that are considered to be suitable for the
incorporation into well-managed home composting installations.
NOTE 1 Compliance with the requirements of this document by the carrier bags entering the compost does not
necessarily imply that a high-quality compost will be produced.
This document covers the suitability of carrier bags for the incorporation into well managed home
composting installations but does not address regulations that may exist regarding the suitability of
anything disposed together with the carrier bag to home composting.
This document provides a set of guidance on the parameters, boundaries and processes required to
engage in well managed, aerobic, home composting. Alternative composting methods and systems may
not provide the conditions necessary for the successful home composting of carrier bags which comply
with the requirements of this document.
NOTE 2 Additional general information about home composting is provided in Annex F.
The testing scheme and the requirements specified by this document do not apply to worm composting,
industrial composting nor community composting. It also does not provide information on the
biodegradability of carrier bags ending up in the environment as litter.
This document includes a reference to features of well-managed home composting (Annex E).
The compost produced via home composting by a private individual is for private use only and not for
provision to others, free of charge or in return for payment. Therefore, this document has no value as a
marketing authorization or authorization of use of the final compost.
NOTE 3 The testing scheme and evaluation criteria could be the basis for the establishment of suitability to home
composting of other products.
NOTE 4 The purpose of testing activity b) is to demonstrate the potential for ultimate biodegradation of the test
material when exposed to microbes active under mesophilic conditions (between 15 °C and 45 °C).
NOTE 5 The purpose of testing activity c) is to verify the thickness and/or grammage that allows a full
disintegration of the test product in a period consistent with a home composting cycle, under defined environmental
conditions. To allow for the potential for variations of local climatic conditions and consumer application of well-
managed home composting techniques, lower than optimal temperature profile has been adopted for this test.

Introduction
EN 13432 specifies the requirements relating to packaging (including carrier bags) recovered through
organic recycling (e.g. aerobic composting) in municipal or industrial biological waste treatment
facilities. Carrier bags compliant with EN 13432 are thus called “compostable” to indicate that they are
suitable for this recovery option. However, the term “composting” is also used to designate “home
composting” and this can generate confusion in the citizen.
Home composting is a practice used by private individuals to treat garden and food waste generated at
household level and produce compost for personal gardening use. In spite of the common name,
industrial and home composting are two very different activities, the former being a controlled waste
treatment process and the latter being a gardening activity.
Home composting is affected by the feeding regime (usually discontinuous in quality, quantity and
intervals), by the composting style of the householder (accurate or careless), and by the local climatic
conditions. The small dimensions of composting installations usually do not allow the generation of heat
enough to sustain high temperatures.
As a result, conditions in home composting can be very different from conditions in industrial
composting. As a result of this, a carrier bag recognized as “compostable” according to EN 13432 cannot
automatically be considered as suitable for treatment in a well-managed home composting installation.
This document has been prepared in order to define the necessary characteristics of carrier bags for
displaying biodegradation and disintegration behaviour compatible with well-managed home
composting installations.

1 Scope
This document specifies a testing scheme and requirements for the designation of carrier bags of any
materials that are considered to be suitable for the incorporation into well-managed home composting
installations run by householders for personal uses. Carrier bags are considered as suitable for home
composting only if all the individual components meet the requirements.
The following five aspects are addressed:
a) characterization;
b) biodegradation;
c) disintegration during home composting;
d) compost quality;
e) recognizability.
The first four aspects (a) to d)) are assessing the effects on the biological treatment process and the
compost made by it. The fifth aspect ensures the recognizability of home compostable carrier bags by the
end user.
This document forms the basis for the labelling of carrier bags of any material that are considered to be
suitable for the incorporation into well-managed home composting installations.
NOTE 1 Compliance with the requirements of this document by the carrier bags entering the compost does not
necessarily imply that a high-quality compost will be produced.
This document covers the home compostability of the carrier bags themselves but does not address
regulations that may exist regarding the home compostability of any residual contents.
The testing scheme and the requirements specified by this document do not apply to worm composting
and/or industrial composting.
It does not provide information on the biodegradability of carrier bags ending up in the environment as
litter.
This document includes a reference to guides to well-managed home composting (Annex E).
Compost produced by a private individual is for his own use and not for provision to others, free of charge
or in return for payment. This document has no value as a marketing authorization or authorization of
use of the final compost.
NOTE 2 The testing scheme and evaluation criteria could be the basis for the establishment of suitability to home
composting of other products.

composting meeting the requirements of this document.
The suitability of carrier bags is verified by the test scheme described in this document.
5 General requirements
5.1 Assessment
5.1.1 General
Except as identified in 5.2 and 5.4, the assessment of the carrier bag or, if applicable, its individual
components shall include the following four assessment procedures:
— characterization (see 5.1.2);
— biodegradation (see 5.1.3);
— disintegration (see 5.1.4);
— compost quality (see 5.1.5).
For recognizability see 5.1.6.

---------------------- Page: 11 ----------------------
oSIST prEN 17427:2020
prEN 17427:2020 (E)
5.1.2 Characterization
Each carrier bag under investigation or if applicable its components shall be identified and characterized
prior testing, including at least:
— determination of the presence of regulated metals;
— evaluation of the presence of substances hazardous to the environment according to
CEN/TR 13695-2;
— evaluation of the presence of substances of very high concern (SVHC);
— determination of volatile solids;
— other relevant identifying characteristics as specified in 6.2.3.
5.1.3 Biodegradation
To be designated as “suitable for home composting”, each component of the carrier bag, if applicable,
shall be intrinsically and ultimately biodegradable as demonstrated in laboratory tests and shall conform
to the criteria and pass levels given in 6.3.
5.1.4 Disintegration
To be designated as “suitable for home composting”, each component of the carrier bag, if applicable,
shall disintegrate in a well-managed home composting process in conformance with the criteria and pass
levels given in 6.4.
5.1.5 Compost quality
To be designated as “suitable for home composting”, no carrier bag and carrier bag component, if
applicable, thereof, submitted to a biological waste treatment process, shall be recorded as having a
negative effect on the quality of the resulting compost as specified in 6.5.
5.1.6 Recognizability
The carrier bag or carrier bag component “suitable for home composting” shall be recognizable as
suitable for home composting by the end user by appropriate means.
5.2 Equivalent form
A carrier bag demonstrated to be in accordance with this document in a particular form, shall be accepted
without additional tests as being in accordance with this document in any other form having the same or
a smaller mass to surface ratio, the same or lower grammage or the same or lower thickness.
5.3 Carrier bag containing different components
The carrier bag or carrier bag component which is intended to undergo the home composting treatment
shall be recognizable as home compostable by the end user by appropriate means.
In case of a carrier bag formed by different components, some of which are home compostable and some
other not, the carrier bag itself, as a whole is not home compostable.
It shall be clearly specified which components of the carrier bag are home compostable.
EXAMPLE 1 A carrier bag with handles made of a different material and sealed to the bag: Handles which are
sealed to the bag and cannot be easily detached are not components. The bag and the handles are considered as a
whole.

oSIST prEN 17427:2020
prEN 17427:2020 (E)
EXAMPLE 2 A carrier bag which is formed by two bags, one containing the other, not or loosely attached to each
other: The two bags can be easily separated one from the other, thus they are components. Specific claims on the
suitability for home composting of each component can be made providing that the whole carrier bag is claimed as
not suitable for home composting, but just one component.
EXAMPLE 3 A carrier bag which is formed by a film made of two layers: The two layers cannot be easily
separated one from the other, thus they are not components. Claim of suitability with home composting can only be
made on the carrier bag as a whole if it complies with this document. No claim on the layers can be made, even if a
layer should individually meet the requirement of this document.
5.4 Materials of natural origin
Chemically unmodified constituents of natural origin, such as wood, wood fibre, cotton fibre, starch,
paper pulp, or jute shall be accepted as being biodegradable without testing (see 6.3). Nevertheless, they
shall be chemically characterized (see 6.2) and fulfil the criteria for disintegration (see 6.4) and compost
quality (see 6.5).
6 Detailed requirements
6.1 General
In order to meet the requirements of this document, a carrier bag shall fulfil all the requirements given
in 6.2 to 6.5.
Test samples shall not be subjected to conditions or procedures designed to accelerate biodegradation or
disintegration prior to testing according to 6.3 or 6.4.
6.2 Characterization
6.2.1 Control of constituents
6.2.1.1 Regulated metals
The concentration of regulated metals in the material under investigation shall not exceed the limits
according to Table 1.

6.2.1.2 Per- and poly-fluorinated substances (PFCs)
From a precautionary perspective, per- and poly-fluorinated substances (PFCs) shall not be intentionally
added to a material of a carrier bag.
The concentration of per- and poly-fluorinated substances (PFCs) in the material of a carrier bag shall be
less than 100 mg fluorine/kg material (dry matter).
The fluorine concentration shall be analysed according to EN 14582.
NOTE 1 Most of per- and poly-fluorinated substances (PFCs) are extremely persistent in the environment and in
addition, certain PFCs are suspected to have bioaccumulative properties and adverse effects for environment and
human health.
NOTE 2 Per- and poly-fluorinated substances (PFCs) have been frequently used as surface-treatment agents in
e.g. tableware in order to enhance grease resistance or to control water permeability.
If a testing on a material containing talcum results in a value of more than 100 mg F/kg material (dry
matter), then, in addition, the total fluorine content of a material without talcum shall be determined. The
measured fluorine concentration of a material without talcum shall be below
100 mg fluorine/kg material in order to meet requirements regarding the restricted use of per- and poly-
fluorinated substances (PFCs).
NOTE 3 Talcum or talc is an inert mineral composed of hydrated magnesium silicate with the chemical formula
Mg Si O (OH) . The mineral is used in many applications including baby care products, cosmetics and packa
