This is a great article titled "From Gunpowder to Teeth Whitener: The Science Behind Historic Uses of Urine" in the Smithsonian magazine

...a quick look back in history shows that urine has always been important to scientific and industrial advancement, so much so that the ancient Romans not only sold pee collected from public urinals, but those who traded in urine had to pay a tax. So what about pee did preindustrial humans find so valuable?



Nothing like the uses listed in this article but...
We use the urine in the garden and compost regularly.
Recently I used stale urine for a fermented lichen dye called orchil with wonderful results.
I sometimes pour extra around the fence as a hopeful animal deterrent.

anyone else?

I'm a big believer in the power of pee. Saving flushing water and keeping all that nitrogen - I wonder why so many are still so resistant to leveraging it. Nothing beats urine in heating up a bin full of shredded leaves (some say it breaks down compost too fast - all bacterial and no fungal activity). Urine is also perfect for charging biochar; and will create lots of methane fast when steeped with chopped up food waste in a biodigester.

Here's one of my favorite videos on the value of urine:
 
The moth suit and wings road is much more exciting than taxes. Or this tiny ad:
