Poorly. Landfills are designed to prevent decomposition—they're dry, compacted, and anaerobic. Compostable bags need oxygen, moisture, and microbes. In landfills, they might actually produce methane. They're meant for composting, not garbage.
Depends on your municipality. Some accept BPI certified bags; others ban all bags (even compostable ones contaminate processing). Check your local program—never assume. When in doubt, empty the bag and compost contents only.
Plant-based materials are inherently weaker than petroleum plastic. Don't overfill, avoid sharp objects, and use within the shelf life. Some brands are thicker—pay more for heavy-duty versions if needed. It's a tradeoff for actual biodegradability.
Keep them sealed in original packaging, in a cool dry place, away from sunlight. Don't store in hot garages or humid basements. Once opened, use within a few months. The material is designed to degrade—storage conditions affect when that starts.
