Paul, Crispin et al,
I do not have any hold of international pricing for charcoal, only specific community pricing, as this assessment is being done routinely by the trainers or should be, before accepting a training contract.
In our local area here in Southern Oregon, based on a look at braii/ bbq charcoal pillow type briquette costs in the local supermarket:
its 88 US cents per pound in 12 to 13.5 pound sacks, and drops to 65 us cents per pound bought in 17 to 18 pound sacks...
The holey briquette using usul blend of the usual leaves grasses stras waste paper and a dash of waste charcoaol fines as produced in the third world sells for a high of 5 cents for a 140 gram briquette...Thats 454/140 X.05 = 16 US cents a pound. Assuming about 95% of the cost is labor, At $3.00/person/day. and given no change in technology of scale of economies , they could be produced here in Obamaland, for $12.00 a day .
Technical improvements are a foot which will likely double of the efficiency of hand production methods, but for what its worth, although the current energy input cost for producing the briquette is far lower in the third world (~3.6 watts/kg of hand-produced product), it seems we are not really competitive in the states at least with the hand processes.
Will be curious to see what you learn in Brazil, Paul...

Rogerio and all,
30 to 40 cents US per Kg for charcoal is real money!!! Even at half those prices (allowing for char fines and processing, etc), it is still much money.
I estimate that a TLUD stove making charcoal could yield 250 to 350 kg of actual carbon (or char with impurities). It is only logical that the poor folks would opt to burn it.
The carbon credit folks, especially those wanting to sequester char from stoves, have a loooooong way to go to complete.
Rogerio, I am in Brazil for the Rio conference. Will you be there? Or where are you in Brazil? After Rio and Amazon excursion, I am back in Sao Paulo from 19 to 23 Sept at contact number for Cassio: SP 4243 9699. Or we talk via email. What are you up to these days???
Paul
