BIODEGRADE THIS: Twelve Traps in Eco Marketing

Scientific accuracy review · 2 October 2026
Qualified regulatory statements and replaced broad environmental shortcuts with evidence questions for the finished product.

Editorial illustration; not experimental footage or evidence.

The packaging aisle is throwing an environmental pageant, and apparently every contestant has awarded itself the crown. “Green.” “Natural.” “Earth-friendly.” Gorgeous adjectives, zero test results. Before another leaf-shaped logo sashays past unchallenged, here are twelve questions for the interrogation lamp.

1. Biodegradable: in what environment, over what period, and measured by what endpoint?
2. Degrades in landfill: does the test represent that disposal environment, and what happens to any generated methane?
3. Compostable: is this commercial or home composting?
4. Home compostable: does a valid certificate cover this actual product?
5. Biobased: what percentage, and is it a carbon percentage or a mass percentage?
6. Eco-friendly: which impact is reduced, compared with what alternative?
7. Oxo-degradable: is the evidence only fragmentation, or does it demonstrate biological conversion?
8. ASTM D5511 tested: an accelerated anaerobic test result is not, by itself, a compostability certification or proof of normal landfill performance.
9. Marine biodegradable: which marine conditions and test specimen were used? This is not permission to litter.
10. Plastic-free: what are all coatings, adhesives and laminates? Not every naturally occurring polymer is classified as plastic.
11. Certified: who certified it, under which scheme, and can the certificate be checked?
12. Fine print: are the disposal limits visible beside the main claim?

The law has a postcode; your adjective does not

The US FTC’s one-year guidance concerns unqualified degradable claims for solid waste after customary disposal. It is not a universal scientific definition of biodegradability. Compostable claims also require appropriate qualification where home composting or access to facilities is limited.

California has additional labeling requirements. CalRecycle lists specific ASTM specifications for compostable plastic products and coated fibre products, and OK compost HOME certification for home-compostable claims. Certification alone does not settle every legal labeling requirement.

For a purchase, ask for the certificate and disposal route. For a commercial label, check current requirements in the markets where it will be sold. A checklist cannot approve the wording for every jurisdiction.

Fine print is where a sweeping promise sometimes remembers it has conditions. Drag those conditions into the main lighting. If the claim needs an asterisk to survive, readers need to see the asterisk.

Ask for the certificate. Ask where the thing actually goes. For commercial labels, check the rules where you sell it. No amount of tasteful kraft brown can do that homework for you.
