I believe in China it was common to site toilets over pig stys. Some loop closing isn't a very good idea.
The toilets fed directly into the pig sty. Very directly down a short chute add though a hole. An eager pig snout poked through the hole could make contact. Never before nor never again have I been so startled.
Pigs don’t eat human faeces...
Chickens will eat egg shells, and it's apparently a good source of minerals for them. You do have to scrunch them up, or else, from what I understand, they start associating egg shells with food, and start pecking their own eggs.
Much of the 'compost' you receive at big-box stores is treated human waste: https://www.epa.gov/biosolids/frequent-questions-about-bioso...
Not much goes to waste in the USA on an industrial scale.
I don't see anything on that page to support this specific claim.
