Buying Guide
- Bin compatibility: Match bag capacity to your bin size (e.g., 1.6–2.6 gallons for small to mid-size kitchen bins).
- Certification scope: Look for OK compost HOME, BPI, and ASTM D6400 to ensure compatibility with home or industrial composting streams.
- Thickness and durability: Thicker bags (around 0.63–0.71 mil) reduce tears and leaks from wet waste like fruit peels and coffee grounds.
- Leakage control: Consider bags with odor control features or robust seals to minimize smells between disposal cycles.
- Storage and shelf life: Some bags advise storage away from heat and note a shelf life; manage supply to avoid bags becoming brittle or degraded.
- Cost vs. value: Compare bag counts per package and the inclusion of bonus bags, especially when using multiple bins or frequent composting.
- Disposal flow: Ensure your local program accepts compostable liners, especially if you plan to drop bags into a municipal compost facility or home compost pile.
- Material perception: Plant-based, corn starch, or other bio-based polymers vary in performance; consider whether your primary goal is reduced plastic use or enhanced bin cleanliness.
- Fit flexibility: Some bags claim compatibility with a range of bin diameters; verify measurements to prevent overhang or bag resistance in tight bins.
- Environmental impact: If you value circularity, evaluate end-of-life options and whether the packaging itself aligns with your sustainability goals.
