A method for fractionating biomass material according to ash content, the method comprising: grinding the biomass material to produce a ground biomass and sieving the ground biomass through a first screen to yield: a) a first fraction of biomass particles that does not pass through the first screen and which has a first particle size, and b) a second fraction of biomass particles that passes through the first screen and which has a second particle size, wherein the second particle size is smaller than the first particle size, and wherein the second fraction of biomass particles has a higher ash content than the first fraction of biomass particles; and optionally further comprising: passing the second fraction of biomass particles through a second screen having a finer mesh size to produce a third fraction having a smaller particle size and a higher ash content than the second fraction of biomass particles.
