‘Sustainable packaging’ covers four different things that are easy to confuse — and getting a claim wrong is a greenwashing risk. Here's what PCR, recyclable, refillable and biodegradable each actually mean, and how to choose credibly.
Four different things: PCR (post-consumer recycled) = made from recycled plastic, needs a GRS certificate to claim; recyclable = can be recycled after use, which usually requires mono-material (single-plastic) structures; refillable = a durable outer vessel plus low-cost refills, cutting plastic per use; biodegradable/bio-based = breaks down or is plant-derived, but claims are tightly regulated and often misunderstood. They're not interchangeable — pick based on your brand story and target-market rules, and always back a claim with a certificate.
| Option | What it means | Proof you need |
|---|---|---|
| PCR | Made from post-consumer recycled plastic (30–100%) | Third-party GRS certificate for the % claimed |
| Recyclable | Can be recycled after use — needs mono-material structure | Material compatibility of the whole pack (incl. label/insert) |
| Refillable | Durable outer vessel + replaceable refill | A genuine refill system, not just a marketing claim |
| Biodegradable / bio-based | Breaks down, or is plant-derived (e.g. sugarcane bio-PE) | Certification (e.g. TÜV) — and careful, regulated wording |
Post-consumer recycled plastic replaces virgin plastic in bottles, jars and tubes at 30–100% content. It's the easiest credible sustainability move for most brands and increasingly required by EU PPWR. The rule: never claim a PCR percentage without a third-party GRS certificate from the resin supplier. See PCR packaging.
‘Recyclable’ depends on the whole pack being compatible with a recycling stream. A bottle is only recyclable if its cap, pump, label and any insert are compatible — a mixed-material laminate or a non-PE label can make a ‘recyclable’ pack non-recyclable in practice. The route is mono-material (all-PE or all-PP) structures. This matters most for tubes and pouches.
A refill system pairs a premium, durable outer vessel (kept by the customer) with a low-cost inner refill (repurchased). It cuts plastic per use by up to ~80%, creates a recurring-purchase model and commands a premium at launch. It's a growing format in skincare and colour cosmetics. See refillable systems.
‘Biodegradable’ and ‘compostable’ claims are tightly regulated and often misunderstood by consumers (most don't break down in a landfill or home compost). ‘Bio-based’ (e.g. sugarcane bio-PE) means plant-derived feedstock, not necessarily biodegradable. If you go this route, get proper certification and word the claim precisely to avoid greenwashing exposure.
Three rules: (1) be specific — say ‘30% PCR’, not ‘eco-friendly’; (2) hold the certificate for the exact claim (GRS for PCR, TÜV for bio-based, material compatibility for recyclable); (3) don't imply more than is true. Vague green claims are increasingly challenged by regulators in the EU, UK and US.
Vella sources all four routes from vetted partner factories and — crucially — requires the supporting certificate for every eco claim (GRS for PCR, TÜV for bio-based, mono-material verification for recyclable), passing it to you so your claim is defensible. We also check your format against EU PPWR targets. See the eco & sustainable range.
