Bill Gates' $777,000 grant produces waterless toilet that converts human waste to biochar, a highly porous charcoal.
A revolutionary waterless toilet powered by the Sun, developed to help some of the 2.5 billion people lacking safe and sustainable sanitation around the world, will be unveiled in India this month.
Designed and built using a$777,000 grant from the Bill & Melinda Gates Foundation, the self-contained, waterless toilet with its innovative technology converts human waste to biochar, a highly porous charcoal.
The biochar has a one-two punch in that it can be used to both increase crop yields and sequester carbon dioxide, a greenhouse gas.
The project is part of the Gates Foundation's "Reinvent the Toilet Challenge," an effort to develop a next-generation toilet that can be used to disinfect liquid and solid waste while generating useful end products, both in developing and developed nations, said Linden.
Since the 2012 grant, Linden and his team have received an additional $1million from the Gates Foundationfor the project, which includes a team of more than a dozen faculty, research professionals and students, many working full time on the effort.
