Bioplastic's Benefits: Unlike conventional plastics, bioplastics biodegrade relatively quickly under the right conditions, and they’re made from annually renewable crops rather than petroleum. PLA can also be recycled into more of the same product repeatedly, while plastic can’t.
Early reports suggest that bioplastic can be an effective substitute for petroleum-based plastic. Last July, the Los Angeles Times published an article about Cargill’s Nebraska facility that manufactures PLA from corn. “The end products—which include T-shirts, forks and coffins—look, feel and perform like traditional polyester and plastic made from a petroleum base,” the article reports. “But the manufacturing process consumes 50 percent less fossil fuel, even after accounting for the fuel needed to plant and harvest the corn.”
