Typically, the torrefied biomass needs to be densified to improve its transportation and storage logistics; the densification usually requires a binder because the biomass loses the ability to bind after torrefaction. The binder costs can be in the range of $5–$20 per ton of biocoal plus the binder equipment and related labor costs.
