Buying Guide
Key purchase considerations for compost bags:
- Size compatibility: Select bags that fit your bin capacity (2.6–3 gallons are common for kitchen bins). Check bag dimensions and tolerance for lid clearance.
- Thickness and durability: Thicker bags reduce tearing from heavy or wet waste. 0.63–0.72 mil options offer stronger performance for daily use.
- Certifications: Look for BPI, OK compost HOME, and ASTM D6400 to ensure the bag is industrially or home-compostable as claimed.
- Home vs industrial composting: Some bags are certified for both, but performance can vary depending on the composting facility. Choose based on your disposal practices.
- Material composition: Plant-based origins (corn starch) minimize plastic residue and support eco-friendly disposal, but verify biodegradation timelines for your locale.
- Odor control and seal integrity: Features like leak-proof bottoms and secure ties help manage smells in small spaces.
- Storage and shelf life: Store bags in a cool, dry place to preserve integrity; check the manufacturer’s recommended shelf life.
