The waterless and easy-to-use Nano Membrane is meant to offset this scarcity. The Bill and Melinda Gates Foundation awarded $710,000 for the development of a revolutionary waterless toilet. Four years after the Bill and Melinda Gates Foundation awarded $710,000 for the development of a revolutionary waterless toilet, the technology has received a second financial boost.Researchers will use the money to continue developing the lab prototype of the Nano Membrane Toilet, as developers at Cranfield University call it, and begin field trials in Africa.Estimates suggest more than 2.4 billion people around the world still live in unsanitary conditions. Without access to clean running water, these at-risk communities face life-threatening

A scraper tool then wipes off any residual waste from the bowl.The solid waste stays on the bottom while the liquid rises to the top. Extremely thin fibres, known as nanofibers, are arranged in bundles inside the chamber. They help move the water vapour that exists as part of the liquid waste into a vertical tube in the rear of the toilet.Next, water passes through specially designed bundles that help condense the vapour into actual water, which flows down through the tube and settles in a tank at the front of the toilet.As for the solid waste that’s left behind, a battery-powered mechanism lifts the remaining matter out of the toilet and into a separate holding chamber. There it’s coated in a scent-suppressing wax and left to dry out.Every week, a local technician visits the community to remove the solid waste and water, and replace the toilet’s batteries if needed.Residents can then use the water for tending to their plants, cleaning their homes, cooking, and bathing. The solid waste ends up at a thermo-processing plant to be turned into energy for the community.
