Dedicated feedstocks are perennial grasses and trees grown as crops specifically
to provide the required raw materials to industrial enterprises especially
bioenergy producers. The Bioenergy Feedstock Development Program, funded by the
U.S. Department of Energy, has identified hybrid poplars, hybrid willows,
silver maples, and switchgrass as having the most potential for dedicated use
as bioenergy feedstocks over a wide geographic range. Other feedstocks such as
agricultural and forest wastes, recycled paper, or municipal wastes are
valuable short term bioenergy resources but do not provide the same long term
advantages as dedicated feedstocks.

Where can dedicated feedstocks be grown?
Recent
studies estimate that most of the approximately 400 million acres of land
classified as cropland in the U.S. are suitable for growing dedicated
feedstocks. Perennial grasses and trees can often be economically grown on land
that is not suitable for conventional crops and can provide the same protection
from erosion recommended for agricultural set aside or Conservation Reserve
Program lands.
Once markets are established, land owners will have the option of generating
additional or new income with environmentally sustainable crops.
