Recyclability Grades A–E Explained: What PPWR Means for Your Packaging

The Five Letters That Determine Your Packaging's Future

Article 6 of the EU Packaging and Packaging Waste Regulation (PPWR) introduces something genuinely new in packaging law: a standardised, five-tier recyclability grading system that applies across all 27 member states. Every packaging unit on the EU market will carry a grade — A, B, C, D, or E — and that grade determines not just your compliance status today, but whether your packaging can legally exist on the market in 2030 and 2038.

This isn't a voluntary eco-label or a marketing score. It's a regulatory threshold with hard consequences. If your packaging grades D or E, it's banned from the EU market starting January 1, 2030. If it grades C, you're safe until 2038 — but not after. Only A and B survive long-term.

Here's how the grading system actually works, material by material, with real examples and the common misconceptions that will get you in trouble.

How the Grades Are Determined

The PPWR grading system is based on a single metric: the percentage of the packaging unit (by weight) that is recyclable at scale. "At scale" is the key phrase — it means separate collection, sorting, and recycling infrastructure exists and operates across the EU for that material, not just in one or two member states with advanced systems.

|-------|---------------------|------------------------------|------------------------------|

The calculation: Take the total weight of your packaging unit. Identify every component material. Determine whether each material is recyclable at scale in the EU. Sum the weights of recyclable materials. Divide by total weight. The resulting percentage maps to your grade.

A corrugated cardboard box (200g) shipped with a polyethylene foam insert (20g) and sealed with a polypropylene tape (5g). Total: 225g. Recyclable at scale: cardboard (200g) = yes. PE foam (20g) = no in most member states (flexible foam collection is limited). PP tape (5g) = no (it contaminates cardboard recycling streams if not removed, and most consumers don't remove it). Recyclable weight: 200/225 = 88.9% → Grade C.

That cardboard box — which feels like the most recyclable thing in the world — grades C because of 25g of non-recyclable components. Welcome to PPWR math.

Material-by-Material Breakdown

Paper and Cardboard

*Typical grade range: A to C*

The good news: uncoated, un-laminated paper and cardboard is the most reliably recyclable packaging material in Europe. Collection infrastructure exists everywhere. Recycling rates for corrugated cardboard exceed 85% in the EU. A plain brown corrugated box with no adhesives, no coatings, no plastic windows, and paper-based tape is A-grade — often 100% recyclable at scale.

*What drags the grade down:*

• Plastic coatings and laminations. A cardboard box with a PE lamination layer is now a composite. The fibre might be recyclable, but the plastic layer isn't separated at scale — it ends up as recycling residue. Depending on the lamination weight relative to the total, this drops you from A to C or D.
• Wax coatings. Waxed cardboard (produce boxes, some frozen-food packaging) is not accepted by most paper recycling mills because wax interferes with the pulping process. Grade: D or E.
• Metallic inks and foil stamping. Heavy metallic decoration can contaminate recycling batches. Paper mills have tolerance thresholds, so small amounts of metallic ink may be acceptable — but large areas of foil or metallic coating will fail.
• Food contamination. Grease-stained pizza boxes, oil-soaked bakery paper, and food residues reduce recyclability. In practice, the material is still recyclable but many collection schemes reject visibly contaminated fibre. Conservative approach: assume food-contacted paper/cardboard grades lower.
• Plastic windows. The small plastic window in a pasta box or envelope. It's removable during pulping (screening separates plastic from fibre), but the plastic fraction itself isn't recycled — it becomes residue. A 50g cardboard box with a 2g plastic window: 50/52 = 96.2% → Grade A. The window is light enough that it doesn't tank the grade. But a heavier window changes the math.

Glass

*Typical grade range: A to B*

Glass is infinitely recyclable without quality loss, and Europe has well-established collection and recycling infrastructure. Clear (flint) glass and green glass are A-grade in most configurations. Brown (amber) glass is also A-grade — the colour separation systems work.

*What drags the grade down:*

• Ceramic and porcelain contaminants. A glass bottle with a ceramic cap or porcelain label isn't pure glass. Ceramics don't melt at glass recycling temperatures and create inclusions in new glass products.
• Non-removable metal components. Metal collars, wire cages (like on sparkling wine bottles), and permanent metal fixtures. These are typically removable during crushing and magnetic separation, so they don't affect the grade — but verify with your recycler.
• Opaque and dark-coloured glass. Black glass, heavily frosted glass, and colour-tinted glass that can't be sorted into existing colour streams. Some member states lack dedicated streams for non-standard colours.

*The weight advantage:** Glass is heavy. A 300g glass bottle with a 2g aluminium cap and 1g paper label: 300/303 = 99% → Grade A. The non-glass components are so light relative to the bottle that they don't impact the grade materially.

Metals: Aluminium and Steel

*Typical grade range: A*

Aluminium beverage cans, steel food cans, aluminium aerosol containers — these are among the highest-performing packaging formats under PPWR grading. Both metals are infinitely recyclable, well-collected across the EU, and the recycling infrastructure recovers material at high rates.

Aluminium recycling saves 95% of the energy required for primary production, creating a strong economic incentive that keeps recycling loops running even without regulatory pressure. A standard aluminium can with a printed design and an easy-open end is typically A-grade.

*What drags the grade down:*

• Multi-material cans. Aerosol cans with plastic actuators, plastic dip tubes, and rubber seals. The metal can body is recyclable, but the plastic and rubber components aren't separated at the same facility. Weight matters: a 100g can with 15g of non-recyclable plastic components = 85% → Grade C.
• Laminated foil packaging. Aluminium foil laminated to paper or plastic (pharmaceutical blister packs, condiment sachets, coffee pouches). These are composites — the aluminium layer is too thin to recover economically at scale. Grade: E.
• Coatings and linings. Most metal cans have internal lacquer coatings (epoxy, acrylic) to prevent corrosion. These coatings burn off during metal recycling and are captured by emissions controls — they don't affect recyclability at the grade level.

Rigid Plastics: PET, HDPE, PP

*Typical grade range: A to C*

This is where most packaging lives, and where the grading system creates the biggest operational challenge.

*PET:** Clear, uncoloured PET bottles are A-grade. Blue-tinted PET bottles are B or C — the colour contaminates the clear PET recycling stream. Green PET is worse. Opaque/white PET (often used for dairy) is borderline — it can be recycled but the opacity additive limits applications for the recyclate.

*HDPE:** Natural (unpigmented) HDPE bottles are A-grade. Coloured HDPE — common for cleaning products, personal care, and automotive fluids — is typically B or C. The issue is colour sorting: mixed-colour HDPE recyclate is greyish and limited to low-value applications.

*PP:** PP tubs, pots, trays, and closures are B or C-grade in most configurations. PP recycling infrastructure is less developed than PET and HDPE — collection rates are lower, sorting is less precise, and the economics of PP recycling are weaker. This is improving rapidly, driven by PPWR targets and industry investment, but for now PP grades lower than PET or HDPE.

*What drags rigid plastics down:*

• Carbon black pigments. The single biggest problem in plastic sorting. Near-infrared (NIR) sorters — the standard technology in EU recycling facilities — cannot detect carbon black. A black CPET ready-meal tray is E-grade not because CPET isn't recyclable (it is), but because the sorter can't see it. NIR-detectable black pigments exist and are commercially available — if your packaging uses carbon black, switch now.
• Full-body shrink sleeves. A PET bottle with a full-wrap PVC or PET-G shrink sleeve. The sleeve material contaminates the PET recycling stream because it's not the same polymer. Unless the sleeve is designed for easy removal, the bottle effectively becomes a composite. Grade: D or E.
• Multi-layer structures. A PP tub with an EVOH barrier layer (common for extended shelf-life food packaging). The EVOH layer is a different polymer. At low percentages (under 5%), EVOH in PP is considered compatible by some recyclability assessment protocols. At higher percentages, it's a contaminant.
• Labels, adhesives, and closures. A PET bottle with a PP cap, a paper label with acrylic adhesive, and an aluminium induction seal. The cap and seal are typically separated during the recycling process (sink/float, eddy current), but the label adhesive can contaminate the PET flake if it's not water-soluble at recycling temperatures.

Flexible Plastics: Films, Pouches, Wraps

*Typical grade range: D or E*

This is the problem category. Flexible plastic packaging — LDPE films, multi-layer pouches, stand-up pouches, flow wraps, shrink wrap — is growing faster than any other packaging format and recycling slower than any other.

*Why flexible plastics grade low:*

• Collection infrastructure is weak. Curbside collection of flexible plastics exists in only a handful of EU member states. Most flexible packaging ends up in residual waste or is collected at retail take-back schemes with low participation rates.
• Multi-material construction. A typical stand-up pouch is PET/AL/PE — three materials fused into one laminate. No recycling process separates them economically at scale. This is E-grade in every assessment protocol.
• Contamination. Flexible films used for food packaging carry food residues. Even if the polymer is recyclable, the contamination risk downgrades the material in practice.

*The mono-material transition:** The industry is racing toward mono-material flexible packaging — all-PE pouches that replace multi-layer laminates. These can theoretically be recycled in PE film streams. The technology exists. But the collection and sorting infrastructure for mono-material flexibles is still years behind the packaging innovation. A mono-material PE pouch might be technically recyclable in 2026 but not recyclable at scale — and PPWR grades on "at scale," not "technically possible."

Composites and Multi-Material Packaging

*Typical grade range: E*

Beverage cartons (Tetra Pak, SIG, Elopak — paper/PE/aluminium composite), multi-layer pouches, laminated tubes, blister packs, and any packaging where different materials are bonded in a way that prevents economic separation.

Beverage cartons are an interesting case. The recycling infrastructure exists — dedicated carton recycling plants that separate paper fibre from the PE/Al layer exist in several EU countries. But the PE/Al residue (polyal) is a byproduct that goes to energy recovery or downcycling, not material-to-material recycling. Under PPWR's recyclability assessment, only the paper fraction counts as recyclable. A 30g carton with 75% paper fibre (22.5g) and 25% PE/Al (7.5g): 22.5/30 = 75% → Grade D. This is contested — the carton industry argues for a higher grade based on total material recovery, but the current assessment framework is conservative.

Common Misconceptions That Will Get You in Trouble

"Bio-based means recyclable."

No. PLA (polylactic acid) is bio-based, made from corn starch or sugarcane. It is not recyclable in standard plastic recycling streams. PLA looks like PET to consumers but it's chemically different — and if PLA enters the PET recycling stream, it contaminates the batch and degrades the recycled material. PLA packaging in an EU market without dedicated PLA collection and composting infrastructure is E-grade. "Bio-based" and "recyclable" have nothing to do with each other.

"Compostable means recyclable."

No. Compostable packaging (certified to EN 13432) is designed for organic waste treatment, not mechanical recycling. A compostable PLA cup in a PET recycling bin is a contaminant. A compostable film in a paper recycling stream is a contaminant. PPWR grades on recyclability, not compostability — these are different end-of-life pathways with different infrastructure.

"It says 'recyclable' on the package, so I'm fine."

Marketing claims are not PPWR grades. "Recyclable" on a package label means the material is technically capable of being recycled — not that it's actually collected, sorted, and recycled at scale in the markets where you sell. A package that says "100% recyclable" in a green font can still be E-grade if the collection infrastructure doesn't exist. Don't confuse branding with compliance.

"My packaging is paper, so it's definitely A-grade."

Paper with a plastic lamination layer is a composite. Paper with a wax coating is not accepted by recycling mills. Paper with food residue may be rejected by collection schemes. Paper with plastic windows, metallic foiling, or synthetic adhesives may grade lower than you expect. Paper is the most recyclable packaging material — but it's not automatically A-grade.

"The 2030 deadline is years away — I'll deal with it later."

You're right that D and E grades are allowed until 2030. But packaging redesign takes time — 12 to 18 months for a significant packaging change is normal. Retailers and distributors are already asking for recyclability grades. If you start redesigning in 2029, you'll be competing for supplier capacity with every other company that waited.

What to Do If Your Packaging Is D or E

For D-grade packaging (≥70% but <80%):

You have a smaller gap to close. Focus on the 20-30% of your packaging weight that isn't recyclable. Common fixes:

• Replace a plastic window with a paper-based alternative
• Switch from carbon-black to NIR-detectable black pigments
• Replace PVC shrink sleeves with PET sleeves designed for easy separation
• Eliminate unnecessary secondary packaging that adds weight without adding recyclability
• Switch to water-soluble adhesives that don't contaminate recycling streams
• Replace wax-coated cardboard with uncoated or dispersion-coated alternatives

These changes are typically achievable within a 12-month redesign cycle and don't require fundamental changes to your packaging format.

For E-grade packaging (<70%):

You need a more fundamental redesign. The most common E-grade trajectories:

• Flexible pouch → rigid container. Switch from a multi-layer pouch to a PET or HDPE bottle/tub. This is a format change, not a tweak, and it affects your filling equipment, logistics, and consumer experience.
• Multi-layer laminate → mono-material. Switch from PET/AL/PE to all-PE. Mono-material PE pouches with barrier coatings exist but availability is limited and prices are higher. Expect 12-18 months for supplier qualification and production transition.
• Composite carton → separated components. Design the carton so the consumer can separate the plastic liner from the paper outer. This shifts the separation burden to the consumer, which improves the grade if the design is intuitive.
• Switch material entirely. Replace a complex plastic format with paper, glass, or metal — materials with established recycling infrastructure. This is the most disruptive option but often the most future-proof.

While you redesign:

Document your D/E-grade packaging. Acknowledge the non-compliance in your internal records. Build a redesign timeline with milestones. Communicate proactively with major customers and marketplaces about your transition plan. Regulators are more lenient with companies that have a documented, funded transition plan than with companies that appear to be ignoring the requirements.

How DutyScope Automatically Grades Your Packaging

DutyScope's PPWR module handles the grading calculation automatically. Enter your packaging components — material type, weight, food-contact status, colour, coatings, and multi-material configurations — and the system:

• Cross-references each material against EU-wide recyclability-at-scale databases
• Calculates the grade based on the per-unit-weight methodology in Article 6
• Flags components that are likely to grade D or E, with specific recommendations for improvement
• Shows grade-by-country variations (a material recyclable at scale in Germany may not be in Romania)
• Generates a graded packaging profile that feeds directly into your Declaration of Conformity
