MoSan pilot-project in Kenya

In August I went to Naivasha in Kenya to test five MoSan prototypes with families from the peri-urban and informal settlement Karagita. Before I started a cooperation with the American start-up Sanivation. For 4 weeks we tested a closed-loop sanitation service including MoSan toilets, Sanivation solar treatment and feces recycling to energy briquettes. It was an […]

Toilet making part 2

The following days we were testing the material and optimizing some details. The final prototypes are made of 6mm polyethylene in natural white. Other colors are more expensive and are only feasible in bigger quantities. To avoid the transparent look we are currently working on a logo and a sticker plot for the outside of […]

Toilet making 1

First day of deep-drawing (vacuum forming) After the molds were milled we chose different materials and tested the stability and quality. We made samples from ABS plastics, polystyrene (PS) and polyethylene (PE). PE made the best results and has the best properties for our purpose. It is long lasting and very stable in hot climates with high UV-radiation. […]

New MoSan plans and prototyping options

The jute was applied evenly and sticked to the mold. Almost no air bubbles appeared. Unfortunately the inner […]

There shouldn’t be a gap between the several jute layers and the surface should be closed. Especially the urine funnel should have a closed and perfect […]
