Poor pelleting ability of rice straw (RS) discourages its production and utilization as a biofuel. Woody biomass lignin are believed to improve the quality herbaceous agro-residual pellets. This study investigated influence length-to-diameter ratio (L/? = 6 10), pine sawdust (PS) (0, 20, 40 wt%) sodium lignosulfonate (SL) 10 20 on RS pellets produced via mini-pilot scale flat-die pellet mill.
