Title: Is it possible to remove nitrogen from your pee?
Post by: MrBigglesworth on April 24, 2005, 03:11:02 PM
I looked around after I heard someone call urine "nitrogeneous waste" and found that it does contain nitrogen; the chemical formula for urea (which urine contains) is CON2H4 . So is there a way to remove nitrogen from urea/carbamide (which can be obtained by boiling urine)?

Why do you need such info?

Urea forms ammonia anyway..

Sorry Mr. Bigglesworth, but it seems a little too gross to try out.  maybe if you somehow burned it, and trapped the NOx gases, you might get more answers on how to extract N from NOx...

Piss on a fire it wreaks. Also ammonia is dangerous. You have very odd question.

As gross as it may be, I also have looked into this. But instead of thinking about how best to do it, I just went and tried. Not recommended. Smells really bad, and I got nothing useful.

I know that it IS possible, because I read about some process in which they do this in some closed chamber...I remeber it was all equipment that probably cost thousands of $, but I do not remeber the specifics :P . I should have phrased my topic as "How to remove nitrogen from urea with $300 or less---suggestions/methods please". Oh well.

You could simply distil the urine, leaving you with water, and decompose the organic matter, I.E urea with heat.

Then of course, dry the stuff out, as it contains a mixture of phosphate salts and carbon, intimately mixed, which at strong red heat, will evolve white phosphorus, as the phosphate is reduced by carbon, the white P can then be condensed under water and stored.

1)  Urinate into large bottle.
2)  Take urine to the woods and dump on the ground
3)  Urea - Ammonia - nitrifying bacteria can eventually convert to Nitrate

4) nitrate may denitrificate using bacteria and release nitrogen to the atmosphere

costs a lot less than $300, but it is slow
