Human urine is a nutrient rich renewable resource. There is prejudice of using urine and it gets lost down the drain and becomes the cause of concern for receiving environment. Presently a good number of studies has established potentials of bioregenerative reclamation of human urine in aquaculture and hydroponics practices. By this was we can kill the two birds with single stone! We can recover nutrient resources and use it in productive economic practices and avert the pollution.
The urea in urine can be a good source of nitrates for plant production but it must be properly processed in a bio-reactor that breaks down urea by microbial activity, removes the high levels of sodium and chloride ions, and breaks down proteins and amino acids.

RESPECTED Mr. Biswas,
Urine along with the faecal matter is a great source of nutrients. It is being used in Aquaculture these days.
In china, the aquaculture farms are built near the public washrooms and the faecal matter is dumped into the ponda. It gives a great production at cheaper costs.
REGARDS,
When I was working as Fisheries Development Officer in the Government of Nepal then I usually used the safety tank containing human faecal matter and urine after these decomposed and found them productive for major carps like exotic and indigenous carps.
