Experiment 2: Burning feces
A container with cover (made from an oil drum), partly filled with feces and toilet paper (but little or no urine) is put in an well insulated brick oven. At the bottom of the oven burns a fire that heats the drum placed over it. After a period of time the feces in the drum is dried and can be emptied in the fire. The stove has to be efficient enough to ascertain that burning the feces generates enough heat to dry the equal amount of wet feces in the next incoming batch. No additional fuel should be required.
This experiment is about phase #1 of the BathroomBox project. Succeeding phases of how an entrepreneur may develop this project has still to be indicated at this place In further phases we will consider retrieving the nutrients in feces by composting or digesting it. As a start the most important target is to make a slums as pathogen free as possible.
The metal drum with the feces is positioned above a fire in a well insulated forced-vented, brick oven. Every quarter we check the drying process. When we consider the feces dry enough the content of the drum is turned over into the fire.
