Land Use, Land-Use Change and Forestry  Other reports in this
collection  Fact Sheet 4.22. Energy By-Products from Food and
Fiber Wastes  Use and Potential Biomass waste products arising
from traditional agricultural and forest production, and
processing contributes significantly to the energy mix (Hall,
1991; Pingoud et al., 1999; Hall et al., 2000). Resources
include rice husks, corn cobs, cereal straw, bagasse, wood
process residues (bark, sawdust, off-cuts), black liquor, nut
shells, animal manures, and municipal solid wastes. A wide range
of energy conversion routes exist to produce electricity, heat,
or fuels (landfill gas, biogas, producer gas, ethanol, methanol,
briquetted pellets, charcoal, etc.). Currently, a significant
proportion of biomass waste at food and fiber processing plants
is either burned to waste or dumped into landfills for disposal.
Where this dumping entails a disposal cost, use of the resource
for energy production may be economically feasible and reduce
the possibility of local air
