The SmartWaste Waterless Toilet

Designed to improve sanitation and hygiene in Sierra Leone

What

In Sierra Leone, water-borne diseases are extraordinarily common. This problem becomes even worse in the rainy seasons when flooding and poor sanitation come together where they can spread more easily. Another health issue in Sierra Leone is the Ebola virus. This disease spreads incredibly quickly here due to their lack of sanitation facilities, taking the lives of over 4,000 people.


Over 80% of people lack proper sanitation and hygiene facilities, however the government plans to build a new airport,as it is supposedly the country’s most pressing need.

​

In response to United Nations Clean Water and Sanitation Goal, I have designed a way to reduce sewage waste which in turn increase overall health

Ideation

I developed my designs from my initial 'waste' box designing exercise focusing on space saving, minimalisation of single use plastics and modular products in conjunction with my personas

Testing

Final Model

Here shows my final design of the SmartWaste waterless toilet.

Story-boarding

Final design storyboard.png

My final design splits feces from the urine by pushing the see-saw mechanism down, whereas the urine flows over through the grate. There is a back up liquid compartment under the feces container that can be easily emptied.


The feces container is taken to the compost bin site where it is left to dry in the sun. The urine is emptied directly into the container. The compost is spread onto crops and the person bringing the containers gets a token as an incentive to continue disposing properly.

 

30 tokens = 1 free loaf of bread
