Using 3D printing, waste plastic, to make composting toilets

A team of students at the University of Washington just won $100,000 in funding for their project, which will transform plastic waste into pieces for rainwater harvesting systems and composting toilets in the developing world.

The team, Washington Open Object Fabricators (WOOF), took top honors in the 3D4D Challenge, an international contest to leverage 3D printing technologies to deliver real social benefits in the developing world.
