In Australia, scientists have developed an even better bioplastic: It biodegrades at temperatures as low as 33 degrees Fahrenheit – simply by being exposed to moisture and microorganisms in the soil. Your candy bar’s bioplastic wrapper accidentally blows out of the car window as you barrel down the highway? Not a problem. With a little rain, it dissolves in an hour. In a matter of weeks, it disintegrates into carbon dioxide and water.
