Three Words That Mean Different Things
'Biodegradable,' 'compostable,' and 'recyclable' are not interchangeable. They describe different end-of-life pathways with different timelines, conditions, and certification standards. Using the wrong term on your product packaging is greenwashing — and increasingly, it's illegal in markets with environmental marketing regulations (EU Green Claims Directive, US FTC Green Guides).
Biodegradable
What it means: The material can be broken down by microorganisms (bacteria, fungi) into water, CO₂, and biomass. No specific timeline is implied by the word alone — 'biodegradable' without a timeframe and condition is meaningless.
Certification standard: ASTM D5511 (anaerobic biodegradation) or ASTM D5338 (aerobic biodegradation). These tests measure biodegradation rate under specific conditions — landfill, compost, soil, or marine.
Party supply example: Natural latex balloons. Latex rubber biodegrades under composting conditions at a rate comparable to an oak leaf. But in a landfill (anaerobic, dry), degradation is much slower. The claim 'biodegradable' without specifying 'under composting conditions' is misleading.
How to use the claim correctly: 'Natural latex balloons — biodegradable under composting conditions. ASTM D5511 test report available on request.' Include the condition and the standard.
Compostable
What it means: The material breaks down in a composting environment within a specific timeframe (typically 90–180 days) and leaves no toxic residue. 'Compostable' is a stricter, more specific claim than 'biodegradable' — all compostable materials are biodegradable, but not all biodegradable materials are compostable.
Certification standard: EN 13432 (EU) or ASTM D6400 (US) for industrial compostability. These require 90%+ biodegradation within 180 days, disintegration into fragments under 2mm, and no ecotoxicity. There are also home compostability standards (NF T51-800, AS 5810) with lower temperature requirements.
Party supply example: PLA-coated paper cups. PLA is certified industrially compostable (EN 13432) but NOT home compostable. If your packaging says 'compostable' without specifying 'industrial,' consumers may put it in home compost where it won't break down.
How to use the claim correctly: 'PLA-coated cup — industrially compostable (EN 13432 certified). Not suitable for home composting. Dispose in industrial composting facility where available.'
Recyclable
What it means: The material can be collected, processed, and manufactured into new products through recycling infrastructure. 'Recyclable' does not mean 'will be recycled' — it means the material is technically capable of being recycled if the infrastructure exists.
Party supply example: Uncoated kraft paper bags. These are recyclable in standard paper recycling streams. PE-coated paper cups are technically recyclable but require specialized facilities to separate the coating — in practice, most PE cups go to landfill.
How to use the claim correctly: 'Kraft paper bag — recyclable in standard paper recycling. Check local recycling guidelines.' Do not claim a product is recyclable if recycling infrastructure doesn't exist in the market where it's sold.
The Greenwashing Trap
The most common greenwashing mistakes in party supplies: claiming 'biodegradable' without test reports, claiming 'compostable' for products that require industrial facilities (without stating that), using 'eco-friendly' as a vague umbrella term with no specific certification, and claiming 'recyclable' for products that are technically but not practically recyclable.
Rule: every environmental claim on your product should be backed by a specific certification, test report, or standard that you can provide to retailers and consumers on request.
