Question 1 Biomass is simply organic material that can be converted into useable energy. It is found in forests, fields and barns, in forest industry plants, and in landfills. In Alberta province of Canada biomass includes residues from wood processors diverted from landfill or incineration; forest harvesting residues; wood from fire- and insect-killed forest stands; agricultural crop residues; manure from farm livestock operations; municipal waste diverted from landfills; landfill gas for power; and energy crops.
Switch grass is current used for the production of biofuel (Jefferson, McCaughey, May, Woosaree, & McFarlane, 2002).
