Considering the national sugar-cane production in 2008/2009
(BEN, 2009) and that each ton produces 6 kg of ash (FIESP/CIESP,
2001) containing 33% charcoal, the estimated volume of charcoal
that will be produced is greater than one million tons in the 2009
harvest. Because this research about charcoal in SCBA is new, no
reference for this value is available
