This municipal sludge/poo was to be buried in a landfill, which is the least environmentally damaging method to dispose of your byproduct of eating.
Land application of sludge is another common disposal method but is rife with negative issues. Nasty bio accumulative heavy metals are usually present in municipal sludge due to industrial waste streams mixed in. The industry was swayed towards these disposal methods over incineration twenty years ago. Land application should only be done on tree crops that are subsequently processed into toilet paper.*

One solution to this is stop eating....
A bidet would reduce sludge quantities - who here thinks swiping a piece of paper across your sphincter is a good cleaning method? Do you clean your dishes with a paper towel?
BTW municipal sludge is municipal sludge, not that fancy new speak term they are pushing lately...Biobullsheit....
and thank you physics for my free gravity - it settles everything in life.
