PPWR Design for Recycling: How Recyclability Grades Will Work

PPWR Article 6 introduces a recyclability grading system with no precedent in EU packaging law. From 2030, packaging that fails to meet a minimum recyclability threshold cannot be placed on the EU market. By 2038, even the lowest passing grade (Grade C) is removed. The direction is clear: design for recycling is no longer a voluntary best practice but a legal requirement. This article explains how the grading system works, which packaging types face the highest risk, and what to prioritize in design decisions now.

What Article 6 Requires: The Grading System

From January 1, 2030, all packaging placed on the EU market must achieve a minimum Recyclability Performance Grade. The grading system ranges from Grade A (highest) to Grade E (non-recyclable), with specific thresholds that determine both market access and timelines for compliance.

Grade C is a temporary pass. The regulation gives companies eight years to transition from Grade C to Grade B or better. Designing to Grade C today is designing for obsolescence in 2038. The practical implication is that packaging placed on shelves in 2026 will still be moving through supply chains in 2030 and beyond, making today's design decisions consequential for years to come.

From 2035, the regulation introduces a second threshold: recyclability at scale. This means packaging must not only be theoretically recyclable, but must actually be recycled through EU collection and sorting infrastructure at significant volume. A packaging design that achieves Grade B on paper but is rarely sorted correctly in practice will face market pressure and potential regulatory scrutiny once actual recycling data becomes available.

What Design for Recycling Actually Means in Practice

Recyclability grades are not assigned by declaration or self-assessment. They reflect measurable material properties and infrastructure compatibility. Four factors drive the assessment:

• Sorting compatibility refers to how easily a packaging material can be identified and separated from mixed waste streams. Near-infrared (NIR) scanners in sorting facilities read light reflection to distinguish materials. A mono-material PET bottle produces a clean NIR signal. A laminated pouch combining plastic, aluminum, and paper produces mixed signals that cause misidentification, routing the item to the wrong recycling stream.
• Material separability is about whether components can be physically divided without destroying the recyclate quality. A PET bottle with a PP cap is easily separable: humans or mechanical systems remove the cap before the bottle enters the recycling line. A laminate of fused aluminum and plastic cannot be separated; the mixed material has no recycling pathway and is therefore not recyclable.
• Contamination avoidance means avoiding inks, adhesives, coatings, and pigments that remain in the recycled material and compromise its reuse. Dark pigments like carbon black are the archetypal problem: they block NIR detection, causing dark-colored plastics to be misidentified during sorting. Recycling-incompatible adhesives fused to label stock remain in the recycled resin, reducing its value.
• Dismantling ease refers to the practical step after sorting: can consumers or mechanical systems easily separate components before the packaging enters the recycling stream? Shrink sleeves that wrap tightly around a PET bottle are difficult to remove; the label residue contaminates the bottle. A label applied with a removable adhesive is easier to dismantle by hand or by industrial peeling equipment.

Which Packaging Types Face Grade D or E

Several packaging categories face near-certain Grade D or Grade E classification under the emerging assessment framework:

Multi-material laminates combining plastic, aluminum, and paper are the highest-risk category. Beverage cartons (Tetrapak-style) use layers of polyethylene, aluminum foil, and paper glued together to achieve barrier properties. These cannot be separated by mechanical means. Current industrial recycling recovers only the fiber component; the plastic and aluminum are waste. This type will almost certainly be Grade D.

Flexible packaging with barrier coatings includes multi-layer food contact films designed to protect against oxygen, moisture, and light. A typical snack food package uses PE/EVOH/PE lamination or more complex structures. The layers are bonded so tightly that separation is not economically or technically viable. These will score Grade D under most assessment methodologies. Note that barrier coatings containing PFAS face a separate restriction under Article 5 (see our guide to PPWR PFAS restrictions for food-contact packaging).

Small-format packaging below A4 size (210×297 mm) presents a separate compliance challenge. Many EU sorting facilities use mechanical screens that allow items smaller than A4 to fall through, treating them as contaminants. From a technical standpoint, a small PET bottle may be highly recyclable, but from an infrastructure standpoint, it exits the recycling stream as waste. This creates de facto Grade E status regardless of material composition.

Dark-colored plastics, especially those using carbon black pigment, are invisibly excluded from recycling streams. NIR scanners cannot detect them, causing them to be sorted as contaminants. A dark-colored PE or PP item may be made from virgin resin and be theoretically recyclable, but without NIR visibility, it exits the sorting process as waste.

Paper-plastic composites exceeding 5% plastic by weight occupy a gray zone. The regulation recognizes paper as the dominant material when plastic is below 5%, allowing the composite to be assessed as paper. Above 5%, the item is assessed as a multi-material composite and must achieve much higher recyclability thresholds. Typical paper-lined pouches or coffee bags easily exceed this threshold.

The Mono-Material Advantage

Single-material packaging has a structural advantage in the PPWR grading system. A mono-material design produces a clean NIR signal, enabling accurate sorting and high-quality recycling output. Monograde PP, PET, or polyethylene in a single-layer format will almost always achieve Grade B or better.

This does not mean returning to basic, low-barrier packaging. Modern mono-material alternatives can replicate performance through material blending or layer construction within a single material family. Oriented PP (OPP) combined with cast PP creates a laminate that provides both stiffness and clarity while remaining 100% polypropylene. These laminates maintain the NIR advantages of single-material design while achieving the mechanical properties previously provided by multi-material structures.

Made-for-Recycling certifications (such as those issued by PRE, the Plastic Recyclers Europe initiative) serve as proxy indicators of PPWR compliance. These certifications assess packaging against design-for-recycling principles very similar to those embedded in Article 6. A package certified for recycling compatibility by an independent auditor is unlikely to be Grade D or E under the final delegated acts.

Delegated Acts: What We Know and What Is Still Open

The PPWR regulation text sets the grade thresholds (A, B, C, D, E) and the timelines (2030, 2035, 2038), but the detailed methodology for assessing recyclability is not finalized. The European Commission will publish delegated acts that specify the test protocols, material-specific criteria, and infrastructure assumptions used to assign grades. These acts have not yet been published.

Under Article 6(4), the Commission must adopt delegated acts specifying the design for recycling criteria by 1 January 2028, giving companies roughly two years before enforcement begins. The December 2025 Environmental Omnibus has proposed delaying this deadline, but no amended date has been confirmed. This uncertainty creates a compliance planning challenge: companies need to redesign packaging before 2030, but the detailed design for recycling criteria may not be finalized until 2028 or later.

What is certain is that the assessment methodology will not change the thresholds themselves. Grade A will remain ≥95%, Grade B ≥80%, and so on. The open questions are primarily about how these thresholds are measured. Will assessment be based on laboratory testing of a single packaging item, or on modeling against EU infrastructure? Will the methodology account for regional variation in sorting technology, or use a harmonized European baseline? What assumptions will be made about consumer behavior in preparing packaging for recycling?

Separately, PPWR Article 11 introduces mandatory labelling requirements including a Digital Product Passport (DDP) accessible via QR code. From 2027, packaging must carry machine-readable information on material composition, recyclability grade, and sorting instructions. For companies already redesigning packaging to meet Grade B or better, building DPP-ready labelling into the redesign avoids a second round of artwork changes later.

Waiting for delegated acts is not a viable compliance strategy. The core design principles that drive high recyclability grades are robust across any plausible assessment methodology: mono-material design, NIR compatibility, material separability, and contamination avoidance. Packaging that violates these principles will not achieve Grade B or better under any reasonable assessment framework. Companies redesigning their portfolios around these principles now will have little rework to do when the final acts appear.

How to Start Your Recyclability Assessment Now

Design for recycling decisions made today will determine portfolio compliance in 2030. Here are five concrete steps to take immediately:

• Map your current packaging portfolio by material type and structure. Identify which SKUs use multi-material laminates, flexible film, small formats, dark pigments, or paper-plastic composites. Create a risk matrix showing which types are most likely to be Grade D or E.
• Identify the packaging types that consume the largest volume and drive the highest costs. These are the candidates for Grade C assessment and eventual Grade B redesign. A change to a high-volume SKU has outsized impact on compliance and EPR costs.
• Engage your suppliers on mono-material alternatives. Converters and material suppliers have already begun developing OPP-based, cast-PP-based, and single-resin laminated formats to replace multi-material structures. Mono-material designs also simplify compliance with PPWR recycled content targets (see our guide to PPWR recycled content requirements). Initiate technical conversations now to understand lead times and cost impacts.
• For hard-to-redesign packaging (specialty formats, high-barrier requirements, aesthetic constraints), commission an early Grade C recyclability assessment using available certification frameworks. This surfaces which designs face the tightest timelines for transition.
• Monitor Made-for-Recycling certifications in your supply chain. Work with suppliers to achieve third-party recyclability certifications. These certifications will serve as credible proxies for PPWR compliance until the delegated acts are published.
