Cellulose Biofuel
Wed, 08/13/2008 - 15:44 — gardenspotCellulosic ethanol (also called ceetol) is a biofuel produced from wood, grasses, or the non-edible parts of plants. [1]
It is a type of biofuel produced from lignocellulose, a structural material that comprises much of the mass of plants. Lignocellulose is composed mainly of cellulose, hemicellulose and lignin. Corn stover, switchgrass, miscanthus and woodchips are some of the more popular cellulosic materials for ethanol production. Cellulosic ethanol is chemically identical to ethanol from other sources, such as corn starch or sugar, but has the advantage that the lignocellulose raw material is highly abundant and diverse. (The word "cellulosic" simply refers to the source material.) However, it differs in that it requires a greater amount of processing to make the sugar monomers available to the microorganisms that are typically used to produce ethanol by fermentation.
Energy Projections vs. Energy Realities
The federal Energy Information Administration (EIA) has released a report projecting that "World marketed energy consumption is projected to increase by 57 percent from 2004 to 2030. Total energy demand in the non-OECD countries increases by 95 percent, compared with an increase of 24 percent in the OECD countries."

"Those battling global warming by promoting biofuels may unintentionally be adding to skyrocketing world food prices, creating what one expert calls 'a silent tsunami' in developing nations.
"The rising prices are 'threatening to plunge more than 100 million people on every continent into hunger,' Josette Sheeran, executive director of the United Nations' World Food Program, said on the agency's Web site Tuesday.
