2. Farmers utilizing crop residue as a bioenergy crop might do the following to assure a sustainable production system:

a. Remove as much residue as the market can handle.
b. Consider how residue removal will impact the land based on the geophysical characteristics of the specific location.
c. Always apply extra N fertilizer to subsequent crops to offset the impact of residue removal

5. What is meant by “intangible infrastructure”?

a. Software programs for trading feedstock in the futures market
b. Enzymatic processes for cellulosic feedstock conversion
c. Public works projects, such as road construction, that support the bioenergy industry
d. Public policy, regulatory structures, quality standards, and marketing institutions.


6. How can storage cost of biomass materials be reduced?

a. Allow the materials to decompose prior to transporting them to the storage facility
b. Pre-treat with chemicals to convert materials into a smaller form
c. Compress biomass materials into pellets or bricks to increase bulk density (densification)

b. False


8. Why is it more costly to convert cellulosic material into ethanol compared to use of grain for ethanol?

a. On a per weight basis, cellulosic feedstock materials take up greater volume of storage and transportation space than grains.
b. Pretreatment of cellulosic biomass is required to break apart hemicellulose into sugars for fermentation to ethanol.
c. With thermochemical technologies, additional processing of product is necessary in order to achieve a drop-in transportation fuel.
d. All of the above.
