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.
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."

Check out the Rich Earth Institute in Vermont. They're doing cool experimentation and research.

Not the first time that urine has been used as a raw material at scale

Also check out the CodysLab version of biological urine reuse (aka the giant aquarium filter):

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