You may think it is common knowledge, but there was a reason Black Gold had a contract that explicitly stated waste management cannot divulge where the biosolids are sent.
I highly doubt they filter out heavy metals and pharmaceuticals though. That would be prohibitively expensive plus I hear that plants love Prozac. They crave it apparently.
Eh duh. Obviously you want to use the fertiliser instead of throwing it away.
I thought everyone knew that all countries (probably) use human waste as fertiliser.
The difficulty is to get rid of medicine traces and heavy metals but you can make money with shit.

I think you are correct though, everyone does it.
