Sometimes plastic is useful, like when it forms a barrier between your hand and your dog's poop. These plastic doggie bags are designed to break down more quickly in landfills. And brands cut down on plastic in the rest of their packaging, like using recycled cardboard inner cores for their bag rolls.
Poop is technically compostable, so nothing is stopping some of these bags from being compostable too. Always check with your municipal compost facility to make sure they accept pet waste, and if you compost the bags in your backyard, we don’t recommend using the finished compost on any plants you plan to eat.
