Will the compostable bags start to breakdown if it rains or if they are stored for a long period of time?

The technology used to make compostable bags has improved greatly. The first compostable bags made years ago did tend to break down when stored too long on a shelf or if they came in contact with any moisture. Today, we have much higher-quality bags that have longer shelf lives and can hold up better to outdoor conditions. You will likely notice a difference in brands, so if you don't like one type that you use, try another and it may work better.

Q:What is the difference between 'oxo-biodegradable' and 'compostable'?

Oxo-biodegradable refers to a material that is made from plastic that, over time, will break down into smaller pieces of plastic but never fully degrade. Compostable materials, on the other hand, are made from plant-based materials and will completely biodegrade in a short period of time in a commercial composting operation. Oxo-biodegradable bags, often labeled 'degradable' or 'biodegradable' are not permitted under this new law. Only compostable bags are allowed.
