03/FAQ
Common questions.
What is the difference between biodegradable and compostable? +
Biodegradable means the material breaks down naturally over time. Compostable means the material breaks down within a specific timeframe under specific conditions (industrial composting). Compostable is a stronger claim and requires certification.
Can I claim "compostable" without certification? +
No. Making compostable claims without certification is misleading and may violate EU Unfair Commercial Practices Directive and US FTC Green Guides.
How long is compostable certification valid? +
EN 13432 and ASTM D6400 certifications are valid for 5 years, with annual surveillance audits. OK Compost is renewed annually.
