Recyclability Assessment & Proof: RecyClass, CEFLEX, Cyclos-HTP, and Software Compared

Anyone labeling a package as "recyclable" today will need documented proof to back that claim starting August 2026 - not a marketing statement, but a formal assessment against a recognized methodology. The challenge: there isn't one method. There are at least three established approaches, multiple certification bodies, and a growing number of software tools. And anyone managing more than 50 SKUs quickly discovers that manual, one-off assessments simply don't scale.

This article gives you an honest overview - which method fits which use case, what the certificates actually tell you, and why a centralized data foundation is the only viable path to PPWR-compliant documentation.

What the PPWR Actually Requires of You

The PPWR (Regulation EU 2025/40) entered into force on February 11, 2025, and applies from August 12, 2026. From that date, manufacturers and brand owners must be able to demonstrate that their packaging meets recyclability requirements.

The requirements are phased:

• From 2030: All packaging must be designed for material recycling (Article 6 PPWR).
• From 2035: Packaging must not only be recyclable but must also actually be recycled at scale.
• From 2038: Only packaging in classes A or B may be placed on the market.

The European Commission will establish recyclability performance classes (A-E) through delegated acts, to be adopted by January 1, 2028. Until then, compliance is demonstrated against the existing harmonized standard EN 13430:2004.

The key takeaway for packaging managers: EPR fees will be eco-modulated based on recyclability class - higher classes mean lower contributions. Companies that haven't assessed their packaging will, in all likelihood, end up paying more.

The Three Leading Assessment Methods Compared

RecyClass - The European Standard for Plastic Packaging

RecyClass is an initiative of Plastics Recyclers Europe and has established itself as the de facto reference for plastic packaging across Europe. The methodology operates on two assessment levels:

1. Design for Recycling Certification: A qualitative rating from A to F based on the free online self-assessment tool.
2. Recyclability Rate Certification: A quantitative evaluation of the actually recyclable share within a specific geographic market.

The Design for Recycling certification assesses packaging qualitatively using the RecyClass online tool - the result is a class from A to F that reflects the degree of recyclability. Classes A, B, and C are considered recyclable, as the quality of the resulting recyclate is sufficient for use in closed-loop or cascade open-loop applications.

Issued certificates are valid for three years and must be renewed thereafter. Worth noting: in 2024, RecyClass commissioned a total of 18 test campaigns and updated its Recyclability Evaluation Protocols and Design for Recycling Guidelines based on new scientific findings.

Best suited for: Plastic packaging (PET bottles, PP cups, PE films), brands with EU-wide distribution, companies that need an internationally recognized certification.

Limitations: RecyClass covers plastics only. Glass, paper, metal, and composite materials fall outside its scope.

CEFLEX D4ACE - The Design Guide for Flexible Packaging

CEFLEX is a consortium of more than 180 companies spanning the entire value chain. Its guideline "Designing for a Circular Economy" (D4ACE) is aimed specifically at flexible packaging.

Since its launch in 2020, the D4ACE guidelines have been a recognized reference for packaging professionals - helping the industry design flexible packaging for recyclability and align it with circular economy goals.

The D4ACE guidelines focus on mechanical recycling processes for polyolefin-based flexible packaging - the primary recycling pathway for flexible formats. They concentrate on the mechanical recycling of polyolefin plastics (PE and PP), where large-scale recycling capacity already exists across Europe.

The latest iteration - "Phase 2," published in September 2025 - helps ensure that packaging is 2030-ready and aligned with current legislation.

The current guidelines are based on the most comprehensive flexible packaging-specific sorting and recyclability testing program in Europe, and include refined material compatibility thresholds for barrier layers, coatings, adhesives, inks, metallization, and tie layers.

Best suited for: Multilayer pouches, stand-up pouches, wrap films, thermoform films - anywhere flexible PE/PP structures are at the center of the design.

Limitations: No formal certificate, no official verification mark. D4ACE is a design guide, not a certification body. For PPWR compliance purposes, you will still need a documented assessment from a recognized body.

Cyclos-HTP - The German Specialist with Broad Material Coverage

The cyclos-HTP Institute (CHI), headquartered in Aachen, Germany, is the best-known provider of recyclability assessments in the German-speaking market.

Cyclos-HTP is the leading research and consulting institute for the assessment and optimization of packaging and product recyclability. Approximately 2,000 packaging items are analyzed in depth each year. Recyclability assessments are issued as expert opinions by publicly appointed and sworn experts.

The institute's certificates are recognized across many European countries, including all EU member states, the United Kingdom, Norway, and Switzerland. That broad recognition is critical for companies operating in multiple markets.

The certificate expresses recyclability as both a class and a percentage - indicating how much of the valuable material can be recovered after disposal. A higher class such as AAA+ represents a 100% recyclability level.

Unlike RecyClass, Cyclos-HTP also assesses paper, glass, metal, and composite materials - making it especially relevant for companies with heterogeneous portfolios.

Best suited for: Companies with mixed material portfolios (plastic + paper + metal), the DACH market, companies that need to meet the German minimum standard under the Packaging Act (VerpackG).

Method Comparison at a Glance

Where Manual Assessment Processes Break Down

Individual packages can be assessed reasonably well using the methods described above. The problems start when you're dealing with portfolios of 50, 200, or 1,000+ SKUs.

Common pain points in practice:

• Missing material composition data: Quality assurance managers typically discover that 30-70% of data is missing during initial portfolio assessments. Without complete specification data, no recyclability assessment is possible.
• Version chaos: Packaging gets redesigned, but the recyclability assessment stays tied to the old version. Spreadsheets fall out of sync.
• No audit trail: The PPWR Declaration of Conformity (DoC) requires traceable documentation - which methodology, which version of the guidelines, which assessor, which date.
• Missing supplier data: Recyclability depends on material composition, adhesives, inks, and additives. When suppliers don't deliver this data in a structured format, the entire process breaks down.

Why a Centralized Data Foundation Is Non-Negotiable at 50+ SKUs

For portfolios with more than 50 packaging items, the real challenge isn't choosing the right assessment method - it's the underlying data.

A PPWR-compliant recyclability assessment requires, for every item:

• Complete material composition (layer by layer, including adhesives, inks, and additives)
• Weight shares per component
• Supplier confirmations
• Version control for design changes
• Linkage to the Declaration of Conformity

Managing that in a spreadsheet leads to consistency problems by the third redesign or the second supplier change at the latest.

Packa solves exactly this problem: the platform uses AI to digitize specification data from PDFs, Excel exports, and ERP systems in under 2.5 minutes per item - and links that data directly to the recyclability module and DoC generation. Changes to a packaging item automatically propagate to all dependent assessments and documents.

The result: an audit-ready, centralized data foundation that serves as the basis for both RecyClass and Cyclos-HTP assessments - and generates the PPWR Declaration of Conformity at the click of a button.

Conclusion: Choose Your Method, Build Your Data Foundation, Then Scale

The right assessment method depends on your material mix:

• Plastic packaging -> RecyClass (with certificate for PPWR proof)
• Flexible PE/PP films -> CEFLEX D4ACE as a design guide + Cyclos-HTP or RecyClass for the certificate
• Mixed portfolios -> Cyclos-HTP (broad material coverage, DACH market)
• 50+ SKUs -> None of the three methods scales without a centralized software platform

What all three methods have in common: they require complete, structured packaging data. Companies that don't maintain that data cleanly in a single system will struggle both to run assessments efficiently and to document PPWR compliance properly.

Building a centralized data foundation isn't an IT decision - it's a compliance decision. And it should be made before August 2026.
