How is Ethanol Made?
Dry Milling• Breaking down corn• Liquefaction
1.Preparing the feedstock
2. Fermenting simple sugars3. Recovering the alcohol 4. Recovering non-alcohol materials
Wet Milling
Presoaked corn
Pros vs. Cons
Disadvantages: Amount of energy Not widely available Not compatible with all
automobiles
Advantages: Could cut U.S. trade
deficit Will create jobs Environmentally friendly Reduces U.S.
dependences Safe for all engines
In Conclusion …•Advantages outweigh the disadvantages
•Cost
•Benefits:
Environmentally
Economically
