I just found this article on the net : http://www.motherjones.com/blue_marble_blog/archives/2008/05/8323_some_kid_invent.html

Could this be the solution that we're waiting for to decrease the amount of plastic in our landfills? Interestingly, according to this kid's paper, plastic was broken down into some kind of bacteria - to which I'm not sure of what impact it has on the environment. You guys should check out the comments section for the article too - it's quite interesting ;)
