Nano membrane toilet

Currently, there are still 2.3 billion people in the world without access to basic toilets. Researchers at Cranfield University are hopeful that this statistic will drop after the Nano Membrane Toilet, which they are developing, is brought to the areas which are most in need. These are communities which do not have the infrastructure to support toilets that require running water.

This toilet can treat human waste on-site without water or external energy. It is a contained system which uses a rotating barrier to 'flush' both solid and liquid waste into a receptacle below – all the while blocking odour. The waste products are then separated, with the liquid waste filtered using membranes, into water for reuse at the household level, and the solid waste combusted into ash and energy. The energy is used to power the membrane processes.
