I care for you

The Mobile Dry Diversion Toilet is a composting toilet and targets families in low-income areas without sanitation at the household level. As an urban research project and an industrial design research project, it has been developed with a series of partners in research and in development as well as from practice since 2017.

The highly participatory project development in 2018, during which the design, aesthetics, construction, and material as well as governance, operation, and maintenance were discussed with selected and interested residents of two communities in Lagos (Nigeria) and Addis Abeba (Ethiopia), two non-functional, locally produced test mock-ups were built. In 2019, after another research and development phase, two amended and fully functional prototypes were built in Lagos. The monitored 6-month field trial with two families in Ifelodun, Lagos, have started in September 2019. The evaluation of the results of the trial period will help us to further improve the design and the waste disposal process. The goal is to produce in 2020 a small series at the selling price of 200 US$ or less.

The first phase (2017-2018) was funded by the Stuttgart State Academy of Art and Design, the Baden Württemberg Ministry of Science, Research, and Art, and the Baden-Württemberg Ministry for Environment, Climate, and Energy. The second phase (2018) was funded by the Stuttgart State Academy of Art and Design (workshop in Addis Abeba) and the Heinrich-Böll Stiftung Nigeria (workhop in Lagos). The third phase (2018-2019) was made possible by private donations via the Swiss crowdfunding platform "I care for you" (further design development and research in Lagos) and by the Consulate-General of the Federal Republic of Germany in Lagos (construction and implementation of two locally produces and fully functional prototypes for the 6-month field trials).
