The Scanny bag is NOT a plastic bag, even though it looks similar to one!  The bag contains NO polyethylene which is what plastic bags are made of. Plastic bags are NOT compostable. If you’re not sure if a bag is compostable, check to see if it has a BPI certification logo. If it does not have that, do not accept any claim that the bag is compostable. Plastic bags should NEVER be used in composting! If plastic finds its way to compost and then into the soil, it can become microplastics. Scannies will not make microplastics. Scannies will be 100% consumed and turned into compost.
