Corn Backpack. “From corn starch to biodegradable bag!” WoW! This bag is made from polyactic acid (PLA) and is 100% biodegradable and compostable. PLA is typically made from the sugars in corn starch, cassava or sugarcane. It is biodegradable, carbon-neutral and edible. To transform corn into plastic, corn kernels are immersed in sulfur dioxide and hot water, where its components break down into starch, protein and fibre. 118 FROM CORN STARCH TO BACKPACK
