All Login Compostable products utilise world leading 100% compostable corn starch technology; a polymer based on corn start which breaks down completely, resulting in an extremely low carbon footprint. Despite utilising renewable resources which may not be seen as a strong alternative to plastic, Login Biohybrid poop bags also offer a 100% water tight seal meaning that there is no risk of getting any waste product on your hands when picking up or carrying a Login Compostable poop bag.
