Dean; here here ! And when one adds up the cost of making the char, it does not make sense economically for the small biomass briquetter to spend their time making it as an added activity for their group. Not here in Sacapulas or in Sta Eulalia, Lanquin san Pablo or anywhere else in Guatemala that we can see, and not in East africa and not in the rest of the 67 odd nations who are briquetting now either. And it is the economic sense of it all that determines its sustainability, not our personal feelings about the envionment and such. Bio char is great in itself but for budda's sake, I fee that one should be using the char from the previous fire and from the charcoal seller to make more charcoal briquettes which makes more char etc… Our numbers suggecst that its quite sustainable as a fuel source --as blended (up to 50% --dry weight to dry weight) into the standard variety of agro-residue briquette at least..
