BioBag Pet Waste Bags come in a variety of sizes and styles to make clean-up for any pet easy. Made from a resin derived from plants, vegetables, oils, and compostable polymers. Unlike regular plastic, BioBags poop bags can be consumed by micro-organisms that live in our soils. Because BioBag use starches from renewable crops, their bags can be readily composted along with organic waste in municipal composting facilities. Great for small to medium dogs of all breeds.
