Many countries don’t still have access to running water. Therefore, some of the most common activities that we do in developed countries like taking a shower, cleaning the dishes or using the tap are not available at all. Among those activities is the use of toilet. We see it as a really common activity, and we don’t think too much about how it works. But, what could we do in a country or situation where no running water is available? The nano membrane toilet looks like a promising solution. Let’s see some of its features.
Nano Membrane Toilet. No water, no smell
It must be taken into consideration that toilets are a private place. In countries where they are not used to using them, many people don’t like using toilets. That’s why it is really important to maintain toilets clean to encourage people using them. If cleaning is important, smells are too. The cabin must be odourless also.
A great development by Cranfield University (UK) can allow achieving those goals. No water is required for the Nano Membrane Toilet to work properly. When you close the lid, a rotation system acts and the waste falls into a sedimentation chamber. Thanks to a special nanotech membrane, sediments are filtered and vapour water is separated. That vapour goes to a “nano-coated hydrophilic beads” where it is condensed and stored to be used for household washing or irrigation.
Regarding the rest of waste, they are conducted through an archimedes screw to other chamber where it is converted into ash and energy. Don’t expect too much energy, but enough for charging a smartphone. As you can see, only ash is produced by this toilet. And it is useful for farming as it is nutrient-rich.
This project has been funded by Bill & Melinda Gates Fundation and is expected to be finished in 2016. Moreover, it is finalist for the Cleantech Innovate Award that will be held the 11th February 2016 in London.
