These extra-large and thick certified home compostable poop bags are great for protecting your hands and accommodating various poop sizes. The roll of bags comes in a recycled cardboard core, which fits most standard dispensers. Meeting both ASTM D6400 and EN13432 standards for compostability, the best way to dispose of these bags is in a secure home compost for non-edible plants. However, keep in mind that pet waste is not accepted in most food waste composting streams. The bags are made of 30% cornstarch and 70% PBAT for an ecommerce website.
