Although it’s a cringe inducing thought for sure, what most laypersons don’t understand is that space flight and long term missions necessarily recycle not only the water in urine, but the aire they breathe as well…
It’s done on the interest of money you see; every pound of throw weight that is saved translates into big dollars. It has a lot to do with the fact that it takes around 90 kilos of expendable mass to put approximately 5 kilos in otbit…
Rest assured though, there aren’t any plans to recycle #2!
In space at least, there are some who feel that here on Earth we are constantly easting sh*t…
Chemistry nitpick: I know “purine” is supposed to be a portmanteau of “Pure” and “Urine”, pronounced “pure-rin”, but it happens to be the name of a specific nucleic acid (and a class of related compounds), and is pronounced, “pure-een”.
And, dang, folks, all the water we drink is from impure sources. It’s all recycled and cleaned up, these days, but anybody who ever drank out of a “pure mountain stream” was drinking deer piss and worse — and that’s most of humanity for most of history.
I’m frankly astonished this wasn’t being done all along. ‘Bout time.
I hate to mention it to you, but the water you’re drinking right now is also purified urine. If it’s Eldorado Springs water, it’s more like purified mammoth urine, it takes a long time to get through that aquifer.

I’m intrigued by the idea, and am happy to let other people to try it out.
Coming soon to a reeducation camp near you.
Pubfodder, Dan. Just saying…
Aw, the Fremen have been doing it for, like, forever.

I hear it goes nice with the Soylent Green, too.

Well, they do have plenty of vacuum to run the still on.
