Why use BioBags Dog Waste Bags instead of grocery bags or other plastic poop bags? Regular polyethylene-based plastic bags (like grocery bags or regular poop bags) can take over 100 years to degrade. Less than 2% of all plastic bags get recycled and plastic does not completely recycle. Plastic bags litter our streets, backwoods and waterways. Thousands of animals die from eating or getting caught up in plastic debris.BioBags are superior to other bags. Some manufacturers are blending additives to polyethylene to produce "degradable" bags. Unfortunately, this process fragments the bags into pieces of plastic debris that do not meet the ASTM D6400 standard. These pieces cause serious harm when mistaken by animals and birds for food. BioBag products use no polyethylene in the production process. BioBags are also GMO-free!
