This article: https://modernfarmer.com/2022/06/dairy-farmer-turning-manure-into-water/
describes a 10 million dollar machine that makes cow flop into purified fertilizer and distilled water.

Over kill? Yeah, I think so.  I'm sure it uses a bunch of energy, but the organic farmer in this story thinks its worthwhile to the point he has invested his own money in the company.

Compared to traditional composting, it is faster, and it may preserve more nutrients,  nitrogen in particular.
Compared to a biodigester I have no idea.

Could this process be done with a less expensive machine?
Could it be powered with waste heat from charcoal making?
Could it be powered by a biodigester?

I've often thought a solar still could do something similar.

Seems kind of redundant when a cow can already produce fertilizer and milk with no machine required, and the ground is purifying the water waste hopefully.

I have witnessed the use of methane gas produced at part of a process that then powers electricity generation.
I am guessing the system described above does not produce methane.
But has very useful other by products.
 
I do some of my very best work in water. Like this tiny ad:
