Biodegradable

Definition

Biodegradable — Capable of being broken down by microorganisms into natural substances — but conditions and timeframes vary widely.

Biodegradable means a material can be decomposed by living organisms (bacteria, fungi) into water, carbon dioxide, biomass and other natural substances. The term is widely abused: nearly anything will biodegrade eventually under the right conditions.

For the term to be meaningful, look for a third-party standard with a defined timeframe and environment: ASTM D6400 / EN 13432 (industrial compostable), ASTM D6868 (paper coatings), or OK Compost HOME (home compostable). "Biodegradable" with no standard cited is marketing.

Note: compostable plastics often do NOT biodegrade in home compost or marine environments. Check the actual certification, not the leaf icon.

Why Biodegradable matters when you shop

Capable of being broken down by microorganisms into natural substances — but conditions and timeframes vary widely. In practice, the term appears in two very different places: on regulated certification documents, where it has a fixed technical meaning, and in marketing copy, where it is often used loosely to imply a benefit that has never been audited.

Treat Biodegradable as a starting question rather than an answer. Ask who defined it, who checks it, and whether the check covers the whole product or a single component. A claim backed by a named standard, a certificate number and an expiry date is worth far more than the same word printed on a box.

On RevWix, every product page separates verified claims from unverified ones, so when you see Biodegradable attached to a listing you can trace it back to the certification, the material or the company policy that supports it.

Checks to run before trusting a Biodegradable claim

  • Look for a certifierA real standard names the body that audits it. No named body means no audit.
  • Search the public registerMost major schemes publish a searchable licence database — check the brand appears in it.
  • Read the scope lineCertification often covers one line or one factory, not the whole catalogue.
  • Check the full ingredient or material listThe back of the pack overrides anything on the front.

Frequently asked

What does Biodegradable mean in simple terms?+

Capable of being broken down by microorganisms into natural substances — but conditions and timeframes vary widely.

Is Biodegradable a regulated term?+

Partly. Some uses are tied to a formal standard with audits and expiry dates; other uses are unregulated marketing language. The difference is whether a named third party verifies it and publishes the result.

Does Biodegradable guarantee a product is safe or sustainable?+

No single term guarantees that. It tells you one specific thing was checked. A complete picture needs the material, the certification scope, the labour standard behind it, and the packaging or end-of-life story.

How does RevWix use Biodegradable in scoring?+

It only contributes to a score when it is backed by a current, third-party audited document. Unverified uses are shown on the page for transparency but carry no scoring weight.
