Nano Membrane Toilet: Generates energy from human waste

Waterless toilet


A pioneer from a British school, Cranfield University, has invented a new Nano Membrane Toilet. This is a waterless toilet where any system or electric power is not necessary for operating. Nanotechnology was implemented with the purpose of transforming human waste into clean water and energy.

This Nano Membrane Toilet does not need water, and it does not smell. The revolutionary toilet uses a whirling machine to transfer waste towards the holding chamber. This holding chamber consists of Nano-elements. The procedure also blocks off a smell and keeps the seat out of view.

How does Nano-membrane toilet works?

The toilet’s actual design is moderately complicated.

Alison Parker, lead researcher, and lecturer in International water and sanitation at Cranfield water science Institute has elaborated on how this toilet works. She said, “Once the human waste comes in holding chamber, we use membranes that take water out in the form of vapor, which can shorten and available later for people to use in their homes.”

An Archimedes screw system then thrills into gear to send the unwanted material into the second chamber. In the second chamber, unwanted material can be burned and transformed into ash and heat. This second process should be able to create plenty of energy. This energy boosts the entire operation with some waste to charge small devices like mobile phones.

After that, the remaining ash can be used as fuel, while the closed cover and a special whirling mechanism, which replaces the flush system here, will avoid any unwanted fragrance.

The back of the toilet contains the novel coated beads, which work by using the process called ‘prevaporation’, where liquid mixtures are splinted up by vaporization through the membrane. Later the vapor will renew and drain into a collection tank so that it can be used for soaking, household washing, or even human consumption.

Alison said, “Our team’s new design is meant to serve poor urban areas, as those will be easiest to accommodate. It will be very hard to carry out the scheduled maintenance in remote areas, mostly because the toilet needs maintenance every six months needs at a minimum to replace certain parts. Instead, the toilet will be used in dense urban areas where a number of factors make providing good sanitation very challenging, but where it would be possible to facilitate visits from maintenance technician.”

Many people worldwide live without using clean toilets; this new invention is specially planned to solve their problem.

Key features of this latest Nano Membrane Toilet:

  • Designed for single household use.
  • Works by pervaporation process.
  • The toilet uses scraper whirling mechanism instead of the flush system.
  • Clean, odourless and aspirational.
  • Eco-friendly and easy to manage.
