Karl Linden's SolChar sanitation on CNBC
Designed by a team at the University of Colorado Boulder, the Sol-Char toilet uses concentrated solar energy to transform human waste into useful and sellable end products such as solid fuel, fertilizer and heat.
The toilet operates off grid without piped water or sewage. The team received funding from the Bill and Melinda Gates Foundation's "Reinvent the Toilet Challenge."
"This is really trying to address the issue of management of faecal sludge," Karl Linden, Sol-Char Sanitation's principal investigator told CNBC in a phone interview.
