Compostable bags are made in such a way as to be as useful as possible for both you, the consumer, and the composting facility. They must decompose only after you throw them into the appropriate bin, and they are taken to the composting facility. Therefore, we recommend replacing the bag at least once a week, otherwise, they will start composting in your bin. However, bio-waste, regardless of the type of bag, will decompose, that is, 'rot and stink' in the same way.
