Our certified compostable bags are made from a blend of PBAT and vegetable starches and meets the ASTM D6400 and EN13432 Standards for compostability. These scent-free bags are 100% leak-proof and can be disposed of in a municipal compost environment where pet waste is accepted. Municipal composting facilities that accept pet waste do not exist in many communities so be sure to check locally for such facilities in your area. When composting at home, be sure not to use the resulting soil on your food crops as it contains poop.
