[Stoves] re The Ccharcoal project

[Richard Stanley]

Paal/ Crispin,

May I suggest charcoal blended briquettes as an alternative?

A 25% blend using the fines /crumbs otherwise unused at the sellers stall, makes this product look and perform very much like charcoal. And of course it is favored and therfore more easily marketed as a result. 
Hundreds of different local producers are doing it already . If you want to learn about it, go to Lushoto Tanzania (up a bit into the Usambara Mountains) where you can meet  Mama Zaugia Hiza or Marieth Kusaga.. 
 These women are some of the best trainers in Tanzania ....and they do not have a decent email address. 

Here is what a 25% blend looks like. It will compete directly performance wise and typically costs about half to two-thirds as much for a 100% lump of the original charcoal of same weight, same source. That doubles the sellers market or nearly halves the demand for same market..
 
I guess I have difficulty understanding the charcoal problem and the need to make more of it. 
viz., 
From Chad, normal carbonisation during the burn . No charcoal added at all: 


Uganda 25% charcoal fines added to garden variety agro residue bq on left ;

this is from Nepal fan assist gassifer stove,  25% charcoal 


...These folks are all selling their product to the local market to survive...If it was not good they, would not have been able to carry on their business for the past several years. I have hundreds of more examples in about   45 countries now.
  
It really does work. No new charcoal needed. And ou can pull off the remaining ash covered coal for soil remediation if you like...

Lots of people in Canada who can afford any fuel they want choose to cook meat with charcoal. It is a market that is going to last as long as there is cooking, as far as I can see.

It would be great of people in rural areas could generate power form the gases and use it, and sell the charcoal to people in cities. The maximum economic benefit would be spread over the largest number of people that way. It would also spread  sustainable power generation and charcoal production over a large enough area of land to make a sustainable living for the maximum number of people.

Some are proposing to send wood into the cities, make char there and ship the char back. Think of the energy inefficiency that entails. There are (not yet anyway) wood powered road vehicles that can operate on the sustainable energy originating on the farms.

Farmers should be allowing nothing to leave their land unless it is as processed as possible in that region. That takes energy. Turning local produce into exportable products (which includes processed fuels) is the opportunity that we should not kill because we don’t like someone’s current wasteful methods.
