Buffalo Chips

Going to Band-e Amir I noticed two things (ok, so I noticed many things but two things relating to fire fuel) Cow patties and grass piles.
In the wide open prairie/mountain-meadow/tundra(?) I noticed piles of grass everywhere that were apparently being cut/collected for fuel (more on that in a future post) and I also noticed piles of cakes on the walls around the houses. These cakes are actually cow manure shaped into cakes and dried and later used as fuel.
I am sure some people are repulsed by the idea of even touching cow manure but I promise you it is more benign than say omnivore or carnivore excrement. An Indian friend of mine told me about the many ways manure is used in India and I remember seeing some public TV documentary that was suppose to show the poorest of the poor and what they were forced to use as cooking fuel, at the time they got me (I felt sorry for the people) but now I dont feel as sorry for them, well maybe I do but not because they have to touch cow manure.
Afghanistan has very few trees and what few trees are here are either used for construction (beams) or sold to Pakistan (the wood is pretty slow growing and dense thus fetches a fairly high price) so fuel for fire is scarce. If you have ever read a cowboy novel you might remember a reference to someone fetching Buffalo Chips; I remember these references and usually just glossed over them but later it occurred to me that buffalo chips were buffalo paddies. It actually is a pretty good fuel since it dries into a hard (almost chip-board like) discs and is high in cellulose and lignin (from all the grass that the cattle consume) both of which are high in energy (lignin is especially hard for cattle to digest so it usually passes right through their systems) so instead of throwing it out or leaving it in the stalls the people here use it (and hopefully throw the ash onto the fields but I dont know that for sure) for fuel.
This makes me think of biodigesters; if people are willing to collect manure then maybe biodigesters have a place in Afghanistan. Biodigester residue leaves a better fertilizer behind (instead of just carbon ash) not only that I have noticed that human feces is used as fertilizer, in my opinion this is the right idea implemented in the wrong way (processing the human waste to #1 harvest potential energy #2 reduce or get rid of infections that are transmitted through feces) but that is for another post.
