Recently, densified pellet fuel from wood biomass is widely used at North America and Europe as a regenerable and clean carbon neutral bioenergy. High-pressure compaction of sawdust of Hyunsasi-poplar (Populus alba ${ imes}$ P. glandulosa) to form a densified fuel was studied. Calorific and elemental analysis were carried out to assess Hyunsasi-poplar clones as fuels. Hot-press process was adopted for compaction of sawdust and compaction was performed under temperature from 100 to 180$^{circ}C$, at pressure of 250 to 1000 kgf/$ extrm{cm}^2$, and for 2.5 to 10 minutes. Densified fuels were evaluated by its oven-dry density and fines after 5-minute shaking test. The target density and fines of densified fuels were over 1.2 g/$ extrm{cm}^2$ and below 0.5%, respectively. When the press-temperature is over 160$^{circ}C$, densified fuels with density eve. 1.2 g/$ extrm{cm}^2$ and with fines below 0.5% can be produced. And the pressure over 750 kgf/$ extrm{cm}^2$ was effective for this production. It was found that the optimum press condition for preparation of densified fuel was 180$^{circ}C$ -1000 kgf/$ extrm{cm}^2$ minutes.
