Human sewage never mixes well with anything.
A company not too far from here tried to make fertilizer of what came out of your butt after you ate a healthy burrito. Mildly successful at first, but it was just too gross for anyone to really get into.
They could not get rid of the stink, no matter what they tried.
A company out of Wisconsin sells people poop fertilizer that is supposed to be disinfected.
