An ethanol plant is being planned to produce 100,000 metric tons of fuel ethanol per year, using poplar wood as the raw material. a. Design a conceptual process for the ethanol plant. b. Estimate how much poplar wood is needed per year for the ethanol plant. c. Estimate how much forest land is required to produce enough poplar wood for the ethanol plant. d. Estimate how much net energy can be produced through the wood-to-ethanol process. e. Estimate how much less greenhouse gas emission can be achieved when the produced ethanol is consumed as automobile fuel in comparison with the consumption of gasoline with equivalent amount of energy production.
