I would be glad to offer advice to help resolve any problems you may encounter during execution.
One thing to remember is that 90% of the fertilizer is in the urine, which constitutes nearly no health risk when dispersed on the soil. Essentially all the pathogens are in the feces, so there may be more resistence to fertilizing with these. One thing you may like to experiment with is the use of dried and decomposed feces as cover material for the new feces. This inoculates them with beneficial soil microbes that broke down the feces in the previous cycle and no one ever needs to worry about pathogens being set loose into the open environment. Also, if people are concerned about the potential for contact with pathogens with adding cover material, this will remind them to wash their hands, which we wanted them to do anyway (plus we know that if the feces have been treated properly, via heat, composting and/or long storage, there are no significant pathogens). https://www.youtube.com/watch?v=G2sPbBoliSo
In general, I suggest exploring with the users different options for implementing UDDTs, rather than presenting them as a set item. You could even make charcoal from the feces, like Sanivation.
Thank you very much for your valid suggestion and practical thoughts. I will discuss about this in our ECOSAN team. Of course, we will consider this aspect during the implementation. Thank you very much indeed.
Best regards, Thakur and the ECOSAN team of Nepal.
This has been prepared for ECOSAN Plan proposal to submit to ClimateCoLab competition organized by MIT's Center for Collective Intelligence.
ReplyDeleteGood luck with this project.

Please let me know if I can help.
