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 Lawn and Leaf bags are a full 33 gallon capacity and are perfect for communities who have banned regular plastic bags for the collection of yard waste. BioBags can be composted right along with the yard waste in a municipal compost facility. Lawn and Leaf bags hold more waste, are more durable, and are easier to use than paper yard bags.
