Canadian teen discovers plastic-bag-devouring microbe

As part of a science fair project, a Canadian teenager has come up with a way to get plastic shopping bags, which normally take up to 1,000 years to decompose, to break down in as little as three months.

Daniel Burd, a 16-year-old high school student in Waterloo, Canada, reasoned that, because plastic eventually degrades, there is probably some some microorganism out there that breaks it down. If that microbe could be identified, you could expose higher concentrations of it to plastic and break it down faster.

So Mr. Burd did just that. The Waterloo Region Record explains his experiment:

First, he ground plastic bags into a powder. Next, he used ordinary household chemicals, yeast and tap water to create a solution that would encourage microbe growth. To that, he added the plastic powder and dirt. Then the solution sat in a shaker at 30 degrees.
