A toilet that does not need water. Mixing feces and water pollutes water. That makes slums unhealthy. Dry toilets turn feces into dust.
EXPLAIN YOUR IDEA
The lack of water is a big problem. Is not a clever idea to mix water with feces which pollutes water. Dry toilets turn feces into dust which does not occupy much space. After some time it can be removed and mixed with soil and can be used as organic matter. The dry toilet is a normal toilet but there is a lower receptacle that stores feces and urine. There is an electric mechanism that dries up this matter. Feces have a big portion of water. When it dries up it turns into dust which can be stored in little space. After some time it can be removed from the bottom part of the toilet by pulling out a tray which stores all the matter. This can be released in the garden or be mixed with organic matter to make humus. The mechanism can be activated by solar power, normal electric power or by an external dinamo. The deviced can be design for a bigger installation. For example two or more toilets that end up in a big device that dries up all the matter turning it into water steam and dust.
The inhabitants of slums or very dense and populated areas. There is not need to have an outdoor place to put the toilet. There is no need to make a water installation for the toilet either. The dry toilet can be placed everywhere and can be used as a normal toilet. Water is not polluted and unhealthy areas are avoided. It can be implemented in slums, but also in mountain villages, green natural areas and any area with lack of watter supply.
HOW DOES YOUR IDEA TAKE INTO ACCOUNT THE CONTEXT OF URBAN SLUMS AND CLIMATE CHANGE?
Actually this device could be implemented in any city or house because water is going to be more scarce in the future. Is not very smart to mix drinking water with waste and then have to clean it again wasting energy twice in the process (making it drinkable and then cleaning it). I bet all toilets in the future will be dry toilets. And we can obtain a useful product from it. Like organic matter we can use it in our garden or any soil making it more rich in nutrients.
