I wanted to like these, but I found that they didn't biodgrade well. I have a compost tumbler and turned it regularly but the food scraps still would be caught in the bags for quite a while. They will dissolve enough for the liquid to go through the bag when it's in the composting pail making cleanup of the pail a bit of a mess but just doesn't' seem to dissolve in the composter. They work fine as vegetable storage bags though.
