I however am a little nervous about using wood chips or shavings as a carbon stock as it is one of our most overharvested resources, and would be difficult to produce locally. Any ideas on a more sustainable stock to balance the high nitrogen ratio of humanure? soil would be a thought as it is widely available,and has the necessary microbiology to kickstart the composting process. It would however make the necessary temperatures to safely mitigate the potential biohazards of human fecal matter in the soil much more difficult to reach due to its high density. Any thoughts?

Definitely thinking in the grass family for growing the pooper mulch, though.

I tried to remember a proper term but I am a bit tired so stink barrier it is. This is why the particle size is important, too large and the stink permeates. It also means that the bio shield does not need to be thick, just complete.
Michael Kalbow wrote:OK, so I'm pretty new to composting, especially the humanure variety, so my question is this. How do you know what your C:N ration is? Is it by weight? Volume? How do you know if your ratio is correct? Do you use a scale? I can just picture my wife sitting down to 'do her business', then weighing the bucket, then adding peat at a 30 to 1 ratio....

What about confetti shredded newspaper and/or junk mail for carbon stock? Anyone using it currently or for a long range option? I am running into brick walls trying to find wood chips/sawdust - have exhausted all avenues and short of spending a ton on sawdust from the local mill (which defeats the point, in my opinion, of transitioning to a low cost humanure system) I'm thinking about newspapers confetti shredded.
