Corn (Zea Mays) is a popular feedstock for ethanol production in the United States due to its abundance and relative ease of conversion to ethyl alcohol (ethanol). Corn and other high-starch grains have been converted into ethanol for thousands of years, yet only in the past century has its use as fuel greatly expanded. Conversion includes grinding, cooking with enzymes, fermentation with yeast and distillation to remove water. For fuel ethanol, two more steps are included: molecular sieve to remove the last of the water and denaturing to make the ethanol undrinkable.
Current Potential for Use as a Biofuel
Promoters and producers of grass fed beef have made a lot of claims about its nutritional and environmental benefits. One web-based marketer states, “100% grass-fed meats, from any kind of critter, are the most perfect food for man. Grass-fed meats will supply 100% of your body's nutrient requirements in perfect balance. Grass-fed meat is the ONLY food type you can eat exclusively and still have optimal body function.”
