Yeah, City of Memphis sells off their sludge cakes but they have to lay out for, I think it's, a minimum of a year before you can use them as fertilizer. One of the water resources engineers explained it to me one day.
Also of note is that they were dumping raw sewage in the river (Memphis, and everywhere) until sometime in the 70s or 80s when the EPA made everybody stop. Yeah, let's get rid of that pesky EPA!
