The CIRCPACK methodology for glass, metal, paper and cardboard packaging according to EN 13430.
CERTIFY is the CIRCPACK-operated recyclability scheme for the materials that RecyClass does not cover: glass, aluminium, steel, paper and cardboard. The methodology is built on the same four-pillar backbone — Collection, Sorting, Reprocessing, Application — and is aligned with EN 13430:2004.
CIRCPACK operates CERTIFY end to end: we wrote the methodology, we audit against it, and we issue the certificate. That keeps the audit trail short and defensible for retailer and regulator review.
Four pillars assessed in sequence. Most CERTIFY engagements complete in 5–8 weeks.
We map how your pack is collected across target EU markets — kerbside, bring-bank, deposit return — and quantify the share of material that actually enters the recycling stream.
CIRCPACK auditors observe the pack on real sorting lines (glass plants, fibre MRFs, metal beneficiation). We record the ejection behaviour and contamination signature.
We test downstream reprocessing — cullet melt for glass, pulping for fibre, secondary smelting for metals — and check the recovered material meets the relevant input spec.
Closed-loop application check (does the recovered material go back into packaging or a defined end use?), then issue one of three CERTIFY outputs: Design-for-Recycling, Letter of Compatibility, or full Recyclability Assessment.
Brand owners and packaging producers whose portfolio leans on glass, metal or fibre — formats outside the RecyClass plastics scope.
Glass bottles, aluminium and steel cans, paperboard cartons all benefit from a single methodology-aligned certificate.
Corrugated secondary packaging, fibre-based primaries and paper wraps assessed against CEPI pulping protocols.
Audit a full own-label range across multiple materials under one scheme, with one report format.
Send us your packaging spec and we'll come back within 48 hours with a scoped quote, methodology and timeline.
RecyClass covers plastics. CERTIFY covers the other major streams — glass, aluminium, steel, paper, cardboard. Brand owners with mixed-material portfolios use both, side by side.
Yes. CERTIFY is aligned with EN 13430:2004 (Packaging — Requirements for packaging recoverable by material recycling). The alignment statement is part of every certificate.
Most engagements complete in 5–8 weeks. The four-pillar process runs in parallel where possible; the long pole is usually access to a sorting facility for the on-line audit.
