A 100% natural dog poop bags that doesn't pollute! BioDOGradable developed a whole new plastic free technology made from Food Grade Ingredients! That's correct, you could eat the bag(we suggest you don't) as it is made from a blend of corn flour(from waste stalks) and vegetable oils. Along with the sister brand GROW(shopping bags), these new bags compost in the backyard unlike any other bags and leave NO residue. Back to nature and they smell like popcorn! They won't fall apart when "full" either!
