BioBags are the Alternative To Regular Plastic Bags. BioBags are certified compostable, meet ASTM 6400 and are made from a resin based on plant starches, vegetable oils and compostable polymers. BioBag 13 gallon Tall Food Waste bags are sized equivalent to regular tall kitchen plastic bags and fit most kitchen waste cans. These bags are perfect for collecting food waste, paper, and other compostable items. Our Tall Food Waste bags are also great for collecting outdoor waste from small gardening areas.
