"Eco-friendly packaging." "100% recyclable." "Biodegradable." "Made with recycled materials." If you're sourcing packaging in 2026, you've seen all of these claims. Some are legitimate. Some are, at best, misleading. And the gap between the two is getting harder to navigate as regulations tighten.
Here's a practical guide to separating real sustainability from marketing spin.
"Recyclable" — What It Actually Means
A material being technically recyclable doesn't mean it gets recycled. PET is the most recycled plastic in the world (#1 resin code), with recycling rates around 30% in the US and 50%+ in Europe. That's good, but it also means 50-70% of PET still ends up in landfill or incineration.
When a supplier says "recyclable," ask: recyclable where? In what infrastructure? A material that's recyclable in Germany's sorting system might not be recyclable in the US or Southeast Asia.
What to look for: Specific recycling rate data for your target market, not just the word "recyclable."
"Biodegradable" — The Most Abused Term
Here's the thing about "biodegradable": almost everything biodegrades eventually. A glass bottle will biodegrade — it just takes a million years. The term is meaningless without a timeframe and conditions.
What people usually mean is "compostable." But even that has caveats:
- Industrial compostable (EN 13432, ASTM D6400): Breaks down in industrial composting facilities at 58°C+ within 180 days. Most "biodegradable" plastics fall into this category. The problem? Most regions don't have industrial composting infrastructure.
- Home compostable (AS 5810): Breaks down in a home compost bin at ambient temperatures. Much rarer, much harder to achieve.
- Marine degradable: Breaks down in seawater. Extremely rare and not well-regulated.
What to look for: Specific certification (EN 13432, AS 4736, ASTM D6400) and clarity about what type of composting is required.
"Made with Recycled Content" — The One That Matters
This is probably the most meaningful sustainability claim a packaging supplier can make. Using rPET directly reduces demand for virgin plastic. But there are details to check:
- Percentage: "Made with recycled content" could mean 5% or 95%. Ask for the specific percentage.
- Post-consumer vs. post-industrial: Post-consumer recycled content (from actual used products) is more impactful than post-industrial (manufacturing scrap). Both are good, but they're not the same.
- Certification: Food-grade rPET requires specific processing and testing. Not all recycled PET is suitable for food contact.
What to look for: Specific percentage, source type (post-consumer), and food-grade certification if applicable.
"Carbon Neutral" — Proceed with Caution
Carbon neutral claims depend entirely on the methodology used. Some companies achieve "carbon neutral" by buying cheap offset credits that don't represent real carbon reduction. Others invest in genuine supply chain improvements.
What to look for: Third-party verification (Science Based Targets initiative, PAS 2060), transparency about what's included in the calculation, and evidence of actual reduction (not just offsetting).
The Bottom Line for Packaging Buyers
When evaluating sustainability claims, apply this test: can the supplier provide documentation?
- "Recyclable" → Can they show recycling rate data for your market?
- "Biodegradable" → Can they show certification (EN 13432, etc.)?
- "Recycled content" → Can they show the percentage and source?
- "Carbon neutral" → Can they show third-party verification?
If the answer is no, the claim is marketing, not substance.
