For years, we've searched for an alternative to polyethylene-based plastics for the kitchen, the dog waste and the yard; and we're proud to finally say that we've found an answer in Bio-Bags and Garden Bio-Film. Made from cornstarch, vegetable oil and other renewable resources, all are 100% biodegradable and compostable. The bag is tough enough to handle your household and yard needs and breaks down in about a month.
