What stinks more and why ... diluted or undiluted urine?
Hi Everyone,
I have been using my new design of Waterless Urinal a lot and I am surprised that the stored undiluted urine (even a month old) does not have as strong a smell as I had expected ... certainly less that a poorly used and maintained public toilet. When the urinal is put together, there is essentially no smell thanks to the soil air filter (just an occasional, tiny, vague odor in the moment of urinating); when I open it, it does not smell like roses, but it is not as bad as I had thought.
It seems that urine ferments more when it is diluted and especially if it is spread on a cement or ceramic floor, mixed with dirt.
Are there scientific papers on this?
Does urine require other ingredients to produce ammonia and those other characteristic odors?
Could it be that certain bacteria are missing?
Are there natural, widely available things (like maybe wood ashes) that we could add to the jugs of such urinals, from the start, to help reduce the odor when they are opened?
I mentioned this new design of Portable Waterless Urinal here:

And the details are here on my blog (in Spanish and English):

Thanks.
Best wishes,
Chris Canaday
