South Africa is out to create a sort of revolution - it does not want its urine to go waste but convert it into useful fertilizers. It already has a system of dry toilets in Durban where water is not wasted for flushing the urinals but the urine is passed through pipelines into the ground - this helps in conserving the precious commodity called water.
It now wants to extend the idea, collect the urine and then convert it into fertilizers. The urine or human liquid waste is usually a thing that has more of a nuisance value considering the pungent smell that it generates. But - it is also a rich source of elements like nitrates, phosphorous and potassium that can be used as fertilizers. That is what is being planned for exploitation.
The feasibility study would be undertaken through funds made available by the Bill and Melinda Gates Foundation. The rates for the urine would be $4 per family for a 20-liter can to be collected on a weekly basis.
Hmmm? I got to think about this one...but the possibilities are endless. Do we do this here in the U.S.?
