Nominate for RaHa Solutions, girls and boys, especially adolescent girls from marginalized communities, to increase their opportunities, access to quality services and capacity to lead their own development.

We intend to provide the nominee with hygienic, technological, financial, sociocultural, and environmental friendly option to dispose of human excreta; sani solar

At the moment of use, urine and feces are automatically separated by the urine-diverting user interface.

Feces fall into one of four containers, which are installed, on a turntable located in the drying chamber located below the toilet seat.

Before leaving the toilet cabin, the user positions another container by moving the turntable with the help of the lever (see picture), placed in the cabin.

The feces in the containers are quickly dried and stabilized by the combination of directional airflow and solar radiation in the drying chamber, see video

Considering daily use by 5 persons, the 4 fecal containers are emptied every 5-months only. This measure can be realized easily and hygienically safely by one single person without any special equipment. The disposal of the dried and stabilized residue does not generate a negative environmental impact.

The urine is conducted out of the cabin into the external drying unit where it is converted into a stable, high-quality plant fertilizer. This fertilizer is recovered by the user with the help of a spatula, see video
