The bulk density of agricultural biomass depends on the type of biomass, moisture content, grind size, and pretreatment (Mani et al., 2006). Lower bulk densities, and concerns with uneven and low flowability of straw grinds are critical issues to sustainable production of pellets using pellet mills ( Adapa et al., 2009 ; Larsson et al., 2008 ).
