planetary ball mill (Pulverisette 6, Frisch, Germany). Ball milling was conducted at 300 rpm with cycles of a 10 min milling plus a 10 min pause. The milled bagasse was screened through a 0.25 mm sieve to remove large particles and powder agrregates. The milling times were 30, 60 120 and 180 min resulting in four bagasse size ranges.
