Milk Styrofoam may not sound all that exciting initially, but this seemingly unimportant invention could help make our planet significantly greener very quickly.

Scientists at Case Western Reserve University in Ohio combined clay and milk to create a new kind of Styrofoam that is commercially viable and biodegradable. One third of the Milk Styrofoam had dissolved in a month's time, which is a big upgrade over the thousands of years that it currently takes for Styrofoam to biodegrade.
