Lately at my house we've been getting a lot of packages. And with packages, comes styrofoam. My three-year-old loves styrofoam. Me, not so much. He breaks it up and it makes a huge mess. The little bits get everywhere and they are impossible to clean up. I can only imagine that multiplied by 100 million homes in the U.S. alone. Styrofoam is everywhere, but nobody really thinks about it. It is a $20 billion dollar business in the U.S. and occupies an estimated 25% of the country's landfill by volume. But Eben Bayer is thinking about it. He is a greentech entrepreneur who recently gave a TED talk (embedded below) where he describes the problem and what he is trying to do about it. Instead of using styrofoam packaging, which is a petroleum-based plastic that pretty much never goes away, he and his team have come up with a way to use mushrooms and agricultural waste such as seed husks to grow bio-degradable packaging material.
