Bio Bag 3 Pack. Recently rated #1 by Whole Home Journal! These wonderful waste bags are biodegradable and compostable! We think that using biodegradable bags to dispose of dog waste makes good sense because plastic bags litter our streets, backwoods and waterways. Studies indicate that over 100,000 marine animals and 2 million birds die each year from ingesting or being caught up in plastic debris. BioBags use no polyethylene in the production process and are fully certified by the Biodegradable Products Institute to be 100% biodegradable and 100% compostable. Dog friendly and planet friendly because nature knows the difference!
