Who would have expected a toilet to one-day filter water, charge a cellphone or create charcoal to combat climate change? Well, did you know that in 2012, a team of students and faculty engineers from the University of Colorado Boulder won a grant for nearly $780,000 for its proposal to develop a solar-biochar toilet for use in developing countries throughout the world? It’s true!
The grant was part of the Reinvent the Toilet Challenge initiated by the Bill & Melinda Gates Foundation to address a sanitation challenge affecting nearly 40 percent of the world’s population. The primary goals: to sanitize waste, use minimal water or electricity, and produce a usable product at low cost.
Congratulations CU Boulder on another big step toward sustainability!
