Can switchgrass be pelletized?
Ernst Conservation Seeds and other groups have engaged in trial runs of pelletizing switchgrass biomass. While it has been proven that switchgrass biomass can be successfully pelletized, there are challenges. Switchgrass biomass, while very similar in some ways to wood fiber, does not flow exactly like sawdust. In some mills designed specifically to work with sawdust, the relatively low bulk density and unique physical properties of switchgrass can cause material handling issues. These issues are easily addressed with the correct engineering and mill design.
