I love sustainability in all forms (just ask my roommates who find my obsession with recycling slightly difficult to live with) and apparently so does DesignVerb!
They posted this article about Project Green Bottle, which makes plastic bottles with a chemical that will allow them to break down over time, thus being biodegradable. This is awesome because, as DesignVerb! points out, it factors in the reality that despite the ease of recycling plastic bottles they often end up in landfills. Way to go Project Green Bottle!
