Recently, densified fuels from biomass are widely used North America and Europe as a regenerable and clean bioenergy. Compaction of sawdust of poplars(Populus tomentiglandulosa and Populus davidiana) with starch glue for densified fuel were studied. Calorific and elemental analysis were carried out to assess these species as fuel. Hot-press process was used and compaction was performed under temperatures from 120 to $160^{\circ}C$ and at pressure of 50kgf/$cm^2$ for prescribed time. Densified fuels were evaluated by its specific gravities, compressive strengths and fines. In the case of with-glue system, when the press temperature is $160^{\circ}C$ and press time is above 7.5 minutes, densified fuels with fines less than 5% can be produced. On the contrary, in the case of without-glue system, densified fuels with fines less than 5% can be produced by controlling the press conditions and the moisture content of sawdust.
