[0] Mill residue (from both sawmills and pulp mills) [1] 7,000-10,000 [2] Highly variable depending on operating size of the mill [3] Easily available and accessible Inexpensive Infrastructure to handle feedstock exists [5] Most mill residues will continue to be used at or near the site where wood is processed though at higher energy costs, more might shift to on-site bioenergy production [4] 
Nearly all mill residues are currently being used in wood products such as particleboard and paper, as fuel for heat or biopower, or to make mulch
