BioBag Compost Pail Liners are 100% biodegradable and compostable bags that are a perfect companion for all RSVP compost pails. Made from a certified biodegradable and compostable material, Mater-Bi, they are GMO free and will biodegrade as naturally as the fruit and vegetable scraps inside. BioBag products meet the specifications found in ASTM D6400 and carry the BPI compostable logo. They are approved by the San Francisco Dept. of Environment for their food waste collection program. BioBags are shelf stable, just like paper towels, yet biodegrade quickly when exposed to nature's elements and micro-organisms, leaving no harmful residues behind. Box of 50 bags. 6-Liter capacity.
