Cellulose Ethanol
Cellulose Ethanol: Sustainable Fuel for the Future
Cellulose ethanol is different from "regular" ethanol only in
production. Conventional ethanol comes, from the most part, from corn, and is made by liquefying corn starch and
fermenting it with enzymes that create ethanol. Cellulose ethanol is created from agricultural, industrial, and
commercially grown plant wastes, which include Switchgrass (a crop grown specifically for energy) cereal straws,
paper pulp and sawdust, among other things.
Cellulose ethanol, unlike grain based variants, do not require a fossil fuel in the distillation
process. This means that they do not produce C02 charged greenhouse gases when they're created. A study
from the Argonne National Laboratory found that conventional ethanol produced 20 to 30 percent fewer emissions than
gasoline, while Cellulose ethanol produced 80 percent fewer emissions - a much more noticeable improvement.
Also, since this form of ethanol is produced mostly from waste, it is far more economical to produce.
“The advantage of Cellulose Ethanol is that it can easily become a mass produced fuel for the
future.”
Currently, such wastes are generally disposed of by being plowed back into the soil, burned, or shipped to
landfills. The distillation of this form of ethanol thus opens a new market--an entirely different source of
income--for agricultural workers that they can easily tap into without making many, if any changes to their crop
planning, and without acquiring more farm land. Other types of waste, such as paper sludge, are also good
candidates for ethanol distillation, opening a similar market to paper mills. It normally costs a great deal of
money (eighty some odd dollars per ton) to have paper sludge removed to a landfill. Selling this waste to corporate
bodies interested in creating and selling fuel could change what was once looked at as a necessary expenditure into
a zero loss exchange, and even a net profit.
If cellulose ethanol is so awesome, you ask, how come it hasn't already seen mass production?
Mostly because no one has taken the initiative to build a refinery--a place to actually make the stuff. The
estimated cost for starting and maintaining one would require an enormous amount of capital--as much as $800
million. (This is a 'safe' number, which takes into account a good deal of foreseeable accidents. It is also the
number that cellulose ethanol enthusiasts are hoping to see from a federal grant.)
If you're looking for a good investment in the near future, keep your eyes open on cellulose ethanol. It is almost
assured a strong place in the market. Maybe even a stronger place than oil.
