摘　　要：A comparison of traditional and mobile wood pellet mills found that mobile systems had higher production costs. Wildfire suppression costs have consistently exceeded British Columbia’s budget set for such activities. Pelletization of excess wood for bioenergy applications has been proposed as a possible method of reducing <span style="font-family:Verdana;"><span style="font-family:Verdana;"><span style="font-family:Verdana;">the </span></span></span><span><span><span style="font-family:;" "=""><span style="font-family:Verdana;">overall costs of fighting wildfires.
