[Gasification] Charcoal kilns vs Gasifiers

Is anyone in Brazil using gasifiers for making charcoal/biochar and power? While I was in Brazil in 2010 the local soil scientist talked about using traditional charcoal kilns for making Biochar. I haven’t been following modern biochar production in Brazil except for the charcoal kilns used to supply the pig iron industry like Arcelor-Mittal Bioenergia (180 m3 charcoal/cycle), RIMA, Carbonex, CML, Delta,Eco-charcoal, DPC, and Ondatec. Gasifiers might be an easier route if the heat or power can be used. As you probably know a couple of Ankur gasifiers are being used for Biochar and power here in the US.
I understand that most recent studies in Brazil (CENBIO, UNICAMP, UNIQOESTE, UFRJ, Lora e Nogeuira) have shown that small scale gasifiers are not economic for generating power due primarily to the low load factor compared with the high capital cost. I wonder if a biochar co-product can improve the feasibility of gasification in your economy.
Have any of the traditional boiler suppliers in Brazil, like H. Bremer, developed modern equipment or making charcoal for fuel or biochar? Who are the principal suppliers for pyrolysis and gasification equipment in Brazil?

Brazil has the highest biodiversity of fisn , the tambaqui , from amozonian can eat any nuts , thus vegetarian piranhas as obseved by Darwins may be possible , as well obseved by Mark.L. .When man become problems piranhas need to eat the aquatic grass and bacteria can make protein needed by piranhas , all has conected food web , wheer terra preta can play importnant role too
