Bill & Melinda Gates Foundation:Reinvent the Toilet Challenge

The Reinvent the Toilet Challenge aims to create a

toilet that:

• Removes pathogens from human waste and recovers

valuable resources such as energy, clean water, and

nutrients

• Operates “off the grid” without connections to water, sewer,

or electrical lines.

• Costs less than 5 cents per user per day

• Promotes sustainable and financially profitable sanitation

services and businesses that operate in poor urban

settings.

• Is a truly aspirational next-generation product that everyone

will want to use – in wealthy as well as developing nations.
