Emily Woods wants to make sure that everyone has access to a clean and safe toilet. She says that more than a billion people in the world do not have a toilet, and globally 1,000 children die every day from fecal related infections. Along with her team from Sanivation, Woods is turning fecal matter into fuel, and working to make the world healthier and more efficient.
Sanivation is currently operating in Kenya, placing mobile toilets at households and sending a collection agent to pick up the buckets of waste twice a week. The waste is then taken to the Sanivation center, where a solar concentrator heats the biosolids over 70 degrees Celsius to remove pathogens in the waste. The waste is then further dehydrated in an agglomerator, and turned into charcoal briquettes that are used as fuel for burning.
