Quick FAQ for EU Compostable Packaging Buyers
When did the PPWR start to apply?
The EU Packaging and Packaging Waste Regulation, Regulation (EU) 2025/40, generally applies from 12 August 2026.
However, individual requirements have different application dates. The specific Article 9 compostability requirements for certain packaging apply from 12 February 2028.
For the full timeline, see our PPWR Compostable Packaging 2026 Guide.
Does PPWR apply to compostable packaging?
Yes.
PPWR applies to packaging placed on the EU market, including packaging made from compostable or biodegradable materials.
However, compostable packaging does not sit outside the normal PPWR framework. Buyers still need to consider packaging classification, Article 9, technical documentation, labelling and other applicable requirements.
Does PPWR require all packaging to become compostable?
No.
PPWR does not make compostability a general alternative to recycling.
Article 9 creates specific compostability pathways for certain packaging. Other biodegradable packaging generally remains on the material-recycling pathway under Article 6.
For the detailed three-path structure, see our PPWR Article 9 Compostable Packaging Guide.
Which packaging must be compostable under PPWR Article 9?
Article 9(1) covers specific packaging, including certain permeable tea, coffee and other beverage formats and sticky labels attached to fruit and vegetables.
From 12 February 2028, these formats must meet the applicable industrial-compostability requirements.
Article 9(2) separately allows Member States to require certain additional packaging to be compostable under defined conditions.
Are all produce bags required to be compostable under PPWR?
No.
Article 9(1) specifically refers to sticky labels attached to fruit and vegetables, not every produce bag.
Some produce bags may instead need to be assessed under Article 9(2), depending on their thickness, classification and the rules of the target Member State.
The packaging format must be classified before choosing the end-of-life route.
Is industrial compostable the same as home compostable?
No.
Industrial compostability refers to controlled composting facilities. Home composting takes place under lower and less controlled conditions.
A product that has evidence for industrial compostability should not automatically be described as home compostable.
For the detailed distinction, see our Home vs Industrial Compostable Packaging Guide.
Is EN 13432 enough to prove PPWR compliance?
No.
EN 13432 remains an important technical reference for industrially compostable packaging, but it does not by itself prove full PPWR compliance.
Buyers also need to consider packaging classification, finished-product scope, technical documentation, labelling and other requirements applicable to the specific product and market.
Is a raw-material compostability certificate enough for a finished bag?
Not automatically.
The finished bag may differ from the certified raw material because of:
- film thickness;
- colour masterbatch;
- printing ink;
- additives;
- adhesives;
- handles or closures.
Buyers should verify whether the applicable certification or test evidence covers the finished configuration being purchased.
This is one of the most important checks in a custom compostable bag project.
Does compostable plastic packaging need PPWR recycled content?
Compostable plastic packaging is excluded from the minimum recycled-content percentages established in Article 7(1) and Article 7(2).
That exemption does not mean compostable plastic packaging is exempt from PPWR as a whole. Other applicable requirements still need to be reviewed.
Does compostable packaging require an EU Declaration of Conformity?
Where the applicable PPWR conformity requirements are demonstrated, the manufacturer must draw up an EU Declaration of Conformity under Article 39.
The declaration confirms that the applicable requirements under Articles 5–12 have been demonstrated and must follow the required PPWR structure.
For project documentation, buyers should distinguish between a compostability certificate and the wider PPWR conformity documentation.
What documents should an EU buyer request from a supplier?
Depending on the project, EU buyers may need to review the finished-product specification, material information, applicable compostability certificates, certificate scope, relevant test evidence, technical-documentation inputs, traceability information and EU Declaration of Conformity information where applicable.
The documents should relate to the finished packaging being purchased, not only the base resin.
See our PPWR supplier documentation guide for the detailed document checklist.
What PPWR labels are required for compostable packaging?
Certain packaging covered by Article 9 is subject to harmonised labelling requirements under Article 12.
The applicable label may need to communicate that the packaging is compostable, that it is not suitable for home composting where applicable, and that it should not be discarded in nature.
Do not finalise artwork solely from a supplier’s existing compostability logo. Check the applicable PPWR labelling timeline and requirements first.
Are compostable bags accepted in every EU composting system?
No.
Certification and local acceptance are different questions.
Acceptance can depend on:
- the Member State;
- municipality;
- packaging type;
- certification scheme;
- collection system;
- composting facility.
A certified compostable bag accepted in one market should not automatically be assumed to be accepted in every EU waste system.
Can compostable packaging be discarded in nature?
No.
“Compostable” does not mean a product can be littered, left in soil, discarded in waterways or expected to disappear in any environment.
Compostability depends on an appropriate composting route and defined conditions.
Environmental claims should therefore describe the intended disposal system rather than imply unrestricted biodegradation.
Buyer Decision Table

Does PPWR apply to compostable packaging?
Yes. PPWR applies to packaging placed on the EU market, including compostable packaging. Compostable packaging may have specific rules under Article 9, but it is not outside PPWR.
Which compostable packaging is covered by Article 9?
Article 9 covers specific packaging types, including permeable tea, coffee, or other beverage bags, soft after-use system single-serve units, and sticky labels affixed to fruit and vegetables. Member States may also require some other packaging to be compostable where suitable bio-waste systems are available.
Does PPWR require all plastic packaging to become compostable?
No. PPWR does not make compostability a general substitute for recyclability. Article 9 creates a specific compostability route for certain packaging types and Member State options.
Is industrial compostable the same as home compostable?
No. Industrial compostable packaging is designed for controlled composting facilities. Home compostable packaging is designed for lower and less controlled home composting conditions.
Is EN 13432 enough for EU compostable packaging buyers?
EN 13432 is important for industrial compostability evidence, but buyers still need to check finished packaging scope, thickness, ink, additives, labelling, technical documentation, and target market requirements.
Is a raw material certificate enough for compostable bags?
No. A raw material certificate may not cover the finished bag. Buyers should ask for finished packaging evidence linked to the exact product structure, thickness, ink, and format.
Does compostable packaging need recycled content under PPWR?
Article 7(4)(e) exempts compostable plastic packaging from the minimum recycled-content targets in Article 7(1) and Article 7(2). Other PPWR rules may still apply.
What documents should importers request from suppliers?
Importers should request finished product specifications, material composition, certificate scope, test reports, supplier declarations, technical documentation inputs, artwork review records, carton marking, batch traceability, and Declaration of Conformity information.
Does compostable packaging need a Declaration of Conformity?
Yes. Under Article 39, the EU Declaration of Conformity states that the relevant PPWR requirements have been met.
What labels should compostable packaging use under PPWR?
For certain compostable packaging covered by Article 9, PPWR labelling rules may require information that the material is compostable, not suitable for home composting, and not to be discarded in nature.
Are compostable bags accepted in every EU composting system?
No. Acceptance depends on the packaging type, certification, local bio-waste system, Member State rules, and facility policy.
Can compostable packaging be discarded in nature?
No. Compostability depends on the right composting environment. Compostable packaging should not be discarded in nature or used as a littering claim.
Conclusion
PPWR questions about compostable packaging usually come down to four things:
- What is the packaging?
- Which PPWR pathway applies?
- What does the finished-product evidence cover?
- Which market and waste system will receive it?
A compostability certificate can be important, but it should not be treated as a substitute for packaging classification, technical documentation or product-specific PPWR review.
