Why Article 6 of the PPWR Is Often Underestimated: Recyclability Is Not a Judgment Call

Article 6 of the PPWR sets out a technical, graded and evidence-based framework for assessing packaging recyclability. What matters is not the material name alone, but how design, component separability, sorting, recycling processes and secondary raw material quality interact.

Recyclability sounds straightforward. Article 6 is not. Many companies begin with the predominant material: PP, PET, paper or aluminum. The PPWR requires a different lens. The relevant question is whether the packaging as placed on the market can be separately collected, reliably detected and sorted, and recycled in established systems – without impairing other waste streams and while producing secondary raw materials of sufficient quality to substitute primary raw materials.

This turns recyclability from a broad material claim into an evidence-based assessment of the entire process chain. A pigment, label, sleeve, adhesive, closure or insert can change the result just as much as the main body. And a modification that looks minor to procurement or marketing may require a new technical assessment.

Note: The examples below are intentionally simplified. The specific classification depends on the packaging construction, the actual separation and disposal logic, and the category-specific assessment criteria still to be established.

What Article 6 actually requires

Article 6(1) establishes the basic obligation: all packaging placed on the market must be recyclable. According to the European Commission’s guidance, this principle applies from 12 August 2026. The harmonized assessment, however, is being introduced in stages.

Under Article 6, packaging is recyclable if it is designed for material recycling and, once it becomes waste, can be separately collected, sorted into a specific waste stream and recycled at scale without affecting other waste streams. It is therefore about design for recycling and the reality of the infrastructure.

* 1 January 2030 or 24 months after the entry into force of the delegated acts under Article 6(4), whichever is later. ** For the ‘recycled at scale’ requirement: 1 January 2035 or five years after the entry into force of the implementing acts under Article 6(5), again whichever is later.

Annex II assigns grade A to a weighted DfR result of at least 95%, grade B to at least 80% and grade C to at least 70%. Below 70%, packaging is considered technically non-recyclable. Importantly, these figures are neither recycling rates nor simply the recyclable share of the packaging by weight. The delegated acts will specify how the criteria and sorting efficiency are to be weighted for each packaging category. As of August 2026, these detailed criteria are not yet available.

Check the exemptions: Article 6 contains narrowly defined exemptions, including certain immediate or outer packaging for medicinal products, contact-sensitive packaging for medical devices and specified foods for infants or special medical purposes, packaging for the transport of dangerous goods, and sales packaging made from selected materials. Innovative packaging benefits only from a time-limited derogation under strict conditions. An exemption should therefore never be assumed as a matter of course.

The key question: how are the components assessed?

Article 6 becomes particularly demanding for multi-component packaging. The PPWR distinguishes between integrated and separate components. An integrated component is integral to the packaging unit and its functioning and is typically discarded at the same time as the main body. A separate component must be completely and permanently disassembled from the main body and is typically discarded prior to and separately from it.

This leads to a clear assessment logic: integrated components are generally assessed with the packaging unit. Integrated components that can become separated through mechanical stress during transport or sorting must be assessed separately. Each separate component is assessed separately.

The assessment does not end there. All components must be compatible with established collection, sorting and recycling processes and must not hinder the recyclability of the main body. Theoretical separability or a very low share by weight does not automatically make a component uncritical.

Lead example: the K3 yoghurt cup

A K3 cup – a plastic cup with a cardboard wraparound sleeve – makes the assessment logic tangible. Consider a PP cup, an aluminum lidding foil and a paperboard sleeve. Three materials do not automatically mean three cleanly separated material streams.

For each component, the first step is to determine whether it is integrated or separate and how it actually behaves during use, transport and sorting. If the sleeve remains on the cup, the assessment of the packaging unit must include its effect. If it can demonstrably become separated through mechanical stress, a separate assessment question arises. The sealing foil cannot be classified generically either: one relevant factor is whether it is completely removed for use and typically discarded prior to and separately from the cup.

The technical assessment follows. Does the sleeve cover so much of the main body that near-infrared (NIR) detection is affected? Is the cup reliably assigned to the correct sorting stream? Do paper, adhesive and plastic separate sufficiently during the recycling process? And is the quality of the secondary raw material maintained?

Even small design changes can alter the answers: adhesive coverage and adhesive type, perforation, the material and coverage of the sleeve, or the peel force of the lid. Under the future criteria, the assessment will generally be based on the packaging category and the predominant material. A robust analysis must therefore assume neither idealized consumer behavior nor three perfect separate streams where there is no evidence to support them.

Three common pitfalls in a packaging portfolio

1. Design variants can be technically different variants

Nine flavors use the same cup construction and comparable printing inks. The tenth, however, uses carbon-black-pigmented black plastic or a large sleeve with equivalent pigmentation. For marketing and purchasing, this is a color variant; for sorting, it may be a different product.

Carbon black pigments can absorb NIR radiation and make detection more difficult. Black is not automatically problematic, however: NIR-detectable solutions exist. The pigment system, surface coverage and performance under real sorting conditions are decisive.

The PPWR provides no general safe harbor for packaging groups. Technically identical variants may be able to use the same evidence base – but only if colors, printing, sleeves, adhesives and other assessment-relevant characteristics also behave identically. If a characteristic changes in a way that may affect conformity, the impact must be addressed through change control.

2. The same component can behave differently in different recycling streams

For a meat tray, for example, it matters whether an absorbent pad is inserted loosely or firmly bonded. A bonded cellulose or composite pad can contaminate the intended waste stream with fibers, adhesive residues or product residues. The extent of the impact also depends on the main material and the corresponding recycling process.

PET and PP streams differ, among other things, in washing temperature, washing chemistry and separation mechanisms. The same combination of pad, paper and adhesive can therefore behave differently in a PET stream than in a PP stream. RecyClass protocols illustrate such technical differences, but they are industry references, not the binding PPWR assessment methodology. The regulatory consequences will be determined by the future material- and category-specific criteria.

3. Small components are not automatically small in regulatory terms

Freshness seals, valves, dosing aids, closures, labels and sleeves often account for only a small proportion of the packaging weight. Article 6, however, contains no general de minimis threshold for them. If a component is separate, it must be assessed separately; its low weight does not remove it from the assessment.

For integrated components, the component is included in the assessment of the packaging unit and may become disproportionately relevant through its effect on detection, separation or recyclate quality. In a cigarette pack, for example, the outer film, tear strip and inner liner may have different separation and disposal pathways. Only a complete inventory reveals which assessments are required.

Separation instructions help – but do not replace a technical assessment

An instruction such as ‘Remove the lid completely and dispose of it separately’ may improve consumer behavior. It does not demonstrate that separation occurs reliably, that the component enters the correct waste stream or that it is recycled there to a high standard. Desired behavior and robust technical assessment are two different things.

Article 12 provides for harmonized material labeling in the future. A QR code may additionally contain information on the disposal route for separate components. These tools can support sorting, but they do not resolve design incompatibilities.

Environmental claims are also becoming stricter. For claims concerning packaging properties regulated by the PPWR, Article 14 requires, among other things, that the claimed properties exceed the applicable minimum requirements, clearly specify whether they concern the packaging unit, part of it or the operator’s entire packaging portfolio, and be substantiated in the technical documentation. ‘Recyclable’ is therefore definitively becoming a claim that requires robust evidence.

The right approach: segment packaging technically

Companies seeking to implement Article 6 systematically should not list their portfolios only by material and weight. They need a technical data model that connects the packaging unit, components, separation logic, target waste stream, variants and evidence.

1. Capture the complete packaging unit. Document the main body, layers, closures, labels, sleeves, seals, inserts, adhesives, colors, printing inks, additives and relevant product residues – including the material, weight and function of each.
2. Classify the components. Determine which components are integrated or separate, when they are removed and whether separation occurs through mechanical stress. The actual use and process logic must be supported by traceable evidence.
3. Assign the packaging category and real target waste stream. Assess how the packaging is handled in established collection, sorting and recycling processes. A target waste stream cannot be chosen freely; it must reflect the actual infrastructure.
4. Control variants and changes. Use common evidence only for variants that are demonstrably assessment-equivalent. Changes to color, adhesive, label coverage, sleeve, seal or supplier belong in a controlled change-control process.
5. Consolidate version-controlled evidence. Link supplier data, specifications, sorting and recycling tests, assessment assumptions, legal bases and approvals. This makes it clear which statement applies to which specific packaging version.

This structure makes it possible to prioritize and reduce risks selectively: with a more compatible adhesive, an NIR-detectable color, a smaller label area, a demonstrably separable sleeve or a seal designed for better recycling compatibility. The decisive step is to validate every change against product protection, process capability and its actual effect on recycling.

Conclusion: Article 6 is the technical core of the PPWR

Article 6 is underestimated because recyclability sounds like a simple material property. In reality, the PPWR requires a system view: the specific packaging unit and its components must function across design, collection, sorting and material recycling – and companies must be able to document that performance.

This makes implementation demanding, but manageable. Companies that technically segment their portfolios early can identify critical variants before they become a market-access or cost problem. Those that connect components, target waste streams and evidence cleanly can prioritize design decisions and avoid unnecessary duplication of work.

This is exactly where PPWRify comes in: the software provides a structured representation of complex, multi-component packaging, connects packaging data with conformity and evidence processes, and makes changes traceable.
