It is used in products from cups that keep your drinks hot or cold to packaging material that protects items during shipping. With the above good features, Styrofoam still enjoys a bad reputation. It cannot be recycled without releasing dangerous pollution into the air. The U. S. Environmental Protection Agency says it is the fifth-largest creator of harmful waste.

The researchers will study the worm’s eating habits and digesting system, looking to copy the plastic breakdown but on a larger scale. Once the way can be put into practice, it will make a revolutionary difference to the disposal of plastic. “Solving the issue of plastic pollution is important”, says Wu, a Stanford University environmental engineering instructor. After all, our earth is small and landfill space is becoming limited with too much garbage waiting to be dealt with, he says. About 33-million tons of plastic are thrown away in the United States every year. Plastic plates, cups and containers take up 25 percent to 30 percent of space in America’s landfills.
