I prefer the term "humanure".
One of the reasons why processing human waste is so difficult and expensive is that we are flushing it down the toilet. One pound of waste can contaminate hundreds of gallons of water. And all that water needs to be extracted before the waste can be composted.
I'm not saying that we should all be pooing in a bucket and taking it out back, but there are alternatives.
I just finished reading "Garbage Land" by Elizabeth Royte, which had an interesting perspective on how to handle this waste.
