At Cranfield University they have created, thanks to nanotechnology, a toilet that does not need water. A project in principle aimed at regions without resources, for houses that do not have access to water, but that can undoubtedly be a great advance for society in general. Imagine the amount of water that could be saved globally if any of these inventions were successful and viable.
This toilet, in addition to not using water, prevents odors from emerging.
How Cranfield Nano Membrane Toilet works.
When we activate the mechanism, a lever turns the floor of the container and the waste falls. In a lower compartment the residue is treated, extracting the water in the form of steam through special membranes. Then the steam condenses and is usable in the house for cleaning or in the garden for watering. The waste is stored in a bag coated with a biodegradable nanopolymer that does not allow the odor to pass through. The bag is removed from the system periodically.
They calculate that the cost of maintaining this type of toilet will be 0.05 euro cents per day and user.
