As part of the Bill & Melinda Gates Foundation, former Microsoft CEO Bill Gates took a trip to Washington state to learn about how feces matter can be turned into safe, drinkable water. Over 2.5 billion people have no access to safe sanitation. The Bill & Melinda Gates Foundation, seeing this, has taken up sanitation as a cause it wants to champion by funding programs and innovations to find solutions to the world's biggest challenges.

To help solve this problem of sanitation, Janicki Bioenergy has stepped up. An engineering firm, they created the Omniprocessor which turns waste into electricity, drinking watering ash . Through a conveyer belt, sludge is separated between solid and water vapor. The Omniprocessor could have a significant impact on the sanitation in developing countries.

In an update from his trip, Gates shared how the Omniprocessor is doing work “the way it was intended to do.” Watch a video below on how this unique engineering project is having an impact in Senegal and could change the game for waste management.
