The Nano Membrane Toilet

Treating human waste onsite without external energy or water.

About the Nano Membrane Toilet Project

The Nano Membrane Toilet is being developed in response to the Bill & Melinda Gates Foundation's Reinvent the Toilet Challenge. We are in the third phase of the project which aims to produce a complete human testable toilet by the end of May 2019.

Work started on the Cranfield toilet on Sept 1st 2012 and progress updates will be provided through this website.

We have been inspired by the Round 1 grantees whose designs are detailed below:
