In the quest to reduce plastic waste, compostable bin-liners have emerged as a popular alternative. But how many of these actually break down, and which ones perform best? We've compared 11 compostable bin-liners from around the world to help you make an informed decision.
“Composting is nature's way of recycling. By using compostable bin-liners, we're helping to close the loop.”
To be considered compostable, bin-liners must meet specific standards. The most common certifications are ASTM D6400 (US) and EN 13432 (Europe). Certified products are more likely to break down completely in a commercial composting facility.
What's the difference between compostable and biodegradable?
While 'compostable' and 'biodegradable' often seem interchangeable, they're not. Biodegradable items can take years to break down and may leave behind microplastics or toxic residues. Always look for certifications to ensure your bin-liner is truly compostable.

Frequently asked questions
How long does it take for bin-liners to decompose in a home composting system?+
Home composting systems can take 6-12 months to break down certified compostable bin-liners, compared to 180 days in industrial facilities.
Can I use compostable bin-liners in my food waste caddy?+
Yes, certified compostable bin-liners can be used in your food waste caddy. Avoid using them for non-food organic waste, as this can contaminate the composting process.
Why are certified compostable bin-liners more expensive than regular plastic ones?+
Certified compostable bin-liners use renewable resources and are designed to biodegrade completely. The extra cost reflects the research, development, and certification processes involved.
