Alternative fuel sources for RMH ie animal dung

I was listening to NPR radio this morning and struck with the deforestation in Afghanistan with only 2% land left in forest AND the population's use of wood stoves thru the winter.
Does anyone know of the feasibility for the use of dung? Specifically carnivore dung and perhaps omnivore. The herbivore dung is best returned to soil and composting.

3 points I am curious about:
a. rocket mass heaters burn very hot and once started and could burn almost anything...would they fussy about the carbon source if dried?
b. since the air flow is toward the flame...wouldn't that also take the odor with it?
c. what is the best delivery and shape of the item?...compressed 'poop' logs/sticks, loose or pelleted?

In an era of potable water scarcity and gigantic human waste disposal systems....hmmm...I have thoughts of generators/heat fueled with sewage vs landfill coming to mind as I figure a way to dispose of my dog's and cat's waste.

or has this topic been on other forums that I haven't found yet?

I personally like feeding manure to larvae and byrning coppiced wood better, but your idea seems reasonable, particularly as an interim solution.

Cow patties are a very common fuel source in the third world.

I've tried putting road apples from the horses into the wood boiler. The smell was pretty bad, though I guess in midwinter when you're not hanging around outside to smell it it wouldn't be so bad. It's also possible they needed to be dried more (not that I was using fresh dung -- they were at least mostly dry).

I'd personally prefer to avoid handling waste from cats and dogs as much as possible. My animals just do their thing outside and it all breaks down in good time without my intervention.
