Dear friends of the “urine to fertilizer” idea,

I start a new topic under the theme "Urine reuse", even so it could also fit into other topics as well.

The idea of processing urine to fertilizer is getting more and more momentum, with pilot projects popping up not only at the northern hemisphere. Also in the south scientist are discovering the huge potentials of collecting and processing this valuable resource. To facilitate those efforts, we have now designed a new user-friendly urine-diverting toilet bowl for waterless toilets. This new urine diverting toilet bowl for UDDT´s shall soon be produced in an elegant ceramic version. After one decade of silence around the Otji Toilet we have meanwhile further developed our well documented UDS-toilet bowl. Our first urine diversion toilet bowl was introduced in 2010 and further improved in 2015. It works without two-chamber-system and is therefore very user-friendly. With our current development we designed a ceramic toilet bowl where urine flows trouble-free into a 50mm vertical drainpipe – no clogging and no cross-contamination.

We expect this ceramic toilet bowl, “Otji 3.0”, to enter the market early next year. Interesting is also the dual functioning of the “Otji 3.0”. The
The urine outlet can simply be closed with a rubber stopper to use the “Otji 3.0” for any non-UDS VIP.

We are currently evaluating the market potential for this product to determine the quantity of production. We are planning to bring that South-South-Product on the market at a price range which is similar to comparable plastic pedestals. With these three questions, we like to get a basic idea about potential demand in different regions.

1. Is dry sanitation a frequently present sanitation solution in your country/region?
2.      Is there a demand for waterless ceramic pedestals in your country/region?
3.      Is urine-diversion a subject in your country/region?

We are thankful for every feedback from stakeholders and observers in the field of waterless sanitation, including VIP. 

Kind regards,

Peter Arndt
