If You Care Compostable Trash Bags are made from potato starch. Non-GMO starch potatoes are blended with a certified, fully compostable polymer, making them stronger than bags made from corn starch.
The potato starch used to make these Trash Bags comes from starch potatoes, which are not grown as a food source. These potatoes are too high in starch to be good for food. To produce the same amount of starch from these potatoes as from corn requires 40% less land. Other compostable bags are made from corn which requires more water, but potatoes don’t require irrigation, and need only normal rainfall.
