INTRODUCTION
Most bin bags are made from virgin plastic that takes hundreds of years to break down in landfill. Every time you pull a plastic bin bag out of the roll, you’re contributing to a waste problem that outlives generations. Compostable bin bags are the simple, effective swap that lets you dispose of waste responsibly — they break down naturally, leave no toxic residue, and are certified safe for composting. In this guide, we’ve rounded up the best compostable bin bags in 2026 so you can make the switch with confidence.
Why Switch to Compostable Bin Bags?
Standard plastic bin bags are one of the most unnecessary sources of single-use plastic in the home. Here’s why compostable bin bags are the smarter choice:
- Break down naturally within weeks in the right conditions — not hundreds of years
- Certified safe for home and industrial composting
- Made from plant-based materials like cornstarch, not fossil fuels
- Reduce your household plastic footprint significantly
- Can be used in food waste caddies and general waste bins
- Leave no microplastics or toxic residue behind

How to Choose the Best Compostable Bin Bags
Not all compostable bags are created equal. Here’s what to check before buying:
- Certification: Always look for ASTM D6400 or EN 13432 certification — these guarantee the bag will actually break down properly Size: Match the bag size to your bin — most kitchen caddies take small to medium bags (5–10 litre)
- Strength: Check reviews for durability — thinner bags can split under heavy or wet waste
- Home vs industrial composting: Some bags only break down in industrial composting facilities – check the label if you home compost
- Material: Look for cornstarch or potato starch based bags – avoid bags labelled “oxo-degradable” as these are not truly compostable
- Quantity: Buying in bulk reduces packaging waste and saves money in the long run
