lines of Brazilian normalization; the amount of residual ash was
13.2% (briquettes prepared with sieved charcoal, >1 mm).
Brazil possesses one of the largest charcoal-based industries in
the world, and charcoal represents the main wood fuel in demand
in the country. Brazilian steel and ferroalloy production demand
high volumes of charcoal. Consequently, this sector has diverted
an enormous amount of wood fuel resources into charcoal production.
Households occupy second place in terms of wood fuel consumption
in Brazil for domestic use (Brito, 1997). Therefore,
these kinds of briquettes can reduce the consumption of charcoal
taken from existing forests.
