Unlike typical plastics made from crude oil, “bioplastics” are often made from plant matter such as corn starch, potato starch, cane sugar, and soy protein. A potentially renewable alternative to petroleum-based plastics would have the long-term benefits of reducing global warming pollution and our dependence on fossil fuels, but do bioplastics fit the bill? As they become more ubiquitous—in the form of grocery bags and disposable plates, food containers, and cutlery—numerous concerns have been raised about their true value:
Click here to read the full text of the article. Basically, UCS summarizes studies that show why we should be favoring durable or recycled good over bioplastics. Reasons include the fact that some people recycle (rather than compost) bioplastics, which contaminates the waste stream; the overuse of pesticides, fertilizer, and fossil fuels in the production crops grown for bioplastics; and the inability of most bioplastics to decompose in backyard compost situations.
