Buying Guide: How to choose the right biodegradable liners
- Bin size and compatibility: Match the liner capacity to your bin’s volume (1.6–3 gallons is common for countertop bins). Consider bottom seam design and fit to prevent leaks.
- Certification and disposal: Look for BPI, OK compost HOME or INDUSTRIAL, and EN 13432/ASTM D6400 certifications. Ensure your local facility accepts the bag type you choose.
- Thickness and durability: Thicker bags (0.64–0.71 mil) resist tearing and leaks with wet scraps; thinner ones save material but may tear with heavy loads.
- Handling features: Handles or tie-closures simplify disposal and keep hands clean. This is especially helpful for heavy or messy waste streams.
- Home vs. industrial composting: Some bags are certified for home composting; others require industrial facilities. Check your composting setup before buying.
- Size versatility: If you use multiple bins (kitchen, bathroom, car), choose liners that fit a range of small containers or offer flexible sizing.
