PLA or "corn plastic" is a biopolymer made from polylactide (PLA) that can be derived from starchy plants like corn, potatoes, tapioca, sugarcane, and soy protein. In the U.S., PLA is typically made from corn kernels that are milled and processed to extract the simple sugar dextrose.
These biopolymers perform like plastic, but are made from annually renewable resources like corn plants. PLA offers the cost and performance necessary to compete with traditional petroleum-based materials, but with the crucial benefit of being commercially compostable.
