I'd like to see a useful spectrum of classifications between "lasts forever as a pollutant" and "dissolves in water". As in How biodegradeable is it?. I think that would help make distinctions between the many "biodegradeable" options.
You want something that is just biodegradeable enough that it doesn't become a forever problem, but not biodegradeable enough that it mixes with food or becomes useless as a food container.
The worst offender is compostable bags: They can hold trash for about 1 day before they become the trash.
That's a little weird for a bag designed to hold biodegradable products... have you tried other brands?
I buy mine from Costco and they easily last 2-3 days (the amount of time it usually takes for the pail inside my house to fill up). I take care not to dump wet items in, though not exhaustively so, e.g. coffee grounds are OK, sauce and liquids go down the drain.
