‘Reinvent the Toilet Challenge’ Innovations Showcased at Expo and in Video

High-tech toilets developed through the Bill and Melinda Gates Foundation’s 2011 “Reinvent the Toilet Challenge” were displayed last week at the first Reinvented Toilet Expo in Beijing.

The high-tech toilets, also featured in a video and article in Gates Notes, are innovative products designed to kill pathogens that make people sick and transform human waste into valuable resources at a low cost to users—all without connections to water supply or sewer systems.

In 2011, the Bill & Melinda Gates Foundation initiated the “Reinvent the Toilet Challenge” to bring sustainable sanitation solutions to the 2.5 billion people worldwide who don’t have access to safe, affordable sanitation. The grants were awarded to researchers around the world.

Besides showcasing the “Reinvent the Toilet Challenge” innovations, the Beijing expo from Nov. 6-8, 2018, featured product announcements and funding commitments aimed at accelerating the adoption of innovative, pro-poor sanitation technologies, in developing regions around the world. The Bill & Melinda Gates Foundation joined global innovators, development banks, corporate partners, sanitation utilities, and governments to host the event.
