Earth Rated certified compostable bags can be composted at home or disposed of at any municipal composting facility 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. These bags are scent-free and leak-proof. Need we say more? Ok, we will. They‚Äôre made from a blend of PBAT and vegetable starches, and meet ASTM D6400 and EN13432 Standards for compostability.
