Students at the Prasetiya Mulya Business School in Indonesia have discovered a method of producing eco-friendly building materials from an endlessly renewable resource: Cow dung. The 'Eco-Fae-Bricks' earned the students the winning prize at the University of California, Berkeley's Global Social Venture Competition.

The 'Eco-Fae-Bricks' are lighter, stronger, and definitely more environmentally friendly than conventional clay bricks. The driving force 'behind the bovine' design is to provide housing in developing regions of Indonesia.

Implications - While cow dung may not be the first thing you think of when you start thinking green, its use in construction materials certainly proves you can make gold out of truly anything.
