If the Romans had only known, they could've used chewed watermelon seeds which contain urease. Adding this catalyst greatly speeds up the volatilization reaction from 3-5 weeks to overnight,[0] eliminating the need for Roman laundries to buffer weeks worth of urine as they wait for it to turn into ammonia.
There's a reason why Roman laundries were usually located just outside the city, ideally on the downwind side...
This is an interesting paper. I had read about recycling cow urine in dairies[1] and I wonder if the yeast would be able to make hydroxypatite out of it. At the time I came across this paper I was looking at people creating financial incentives to produce ammonia (and ammonium nitrate) at scale for farming. We import a bunch of it[2] and making it locally would be a win/win.
But is there enough demand for this to make it economical? I would guess the cost of material would be a very small percentage of the cost pf operations that use hydroxyapatite.
Finally, a way to turn urine into bones. I’ve been saying “we need to find a way to turn urine into bones” for years and people told me that it couldn’t be done
Great channel. Quite a shame to hear about Cody's burnout after constant issues getting paid by YouTube, and apparently dating problems with the stigma associated with "youtuber."
There is no need to imagine that. It depends on the country, and your insurance. I've experienced it, not personally, because no need so far (phew!). But when I grew up that was free, for all. Like glasses, too.
Still don't really care, because now it would be covered by my private insurance. If not they'd get sued into oblivion really fast, even if I would be incapacitated somehow.
The Romans used urine as laundry detergent.

Only problem was that watermelon didn’t hit the European side of the empire until the endish

The valuable materials are artificial bone made from hydroxyapatite produced by yeast, used in bone surgery and dentistry.
