Process To Make Ethanol
Net energy balance is a term used to describe how much energy is needed to produce a product versus how much energy that product provides. Two professors that are long-time critics of ethanol claim that ethanol has a negative energy balance, meaning more energy is required to produce ethanol than ethanol offers as a motor fuel.

Fuel Your Car With Cow Hockey?
MEAD, Neb. -- The federal government on Thursday will announce new standards designed to double the production of ethanol and biodiesel. A Nebraska man is convinced his plan can help that effort by using cow manure to make ethanol production more efficient. Mark "Bump" Kraeger works out of an ethanol plant in Mead, where Kraeger's process reduces the cost of ethanol production. "It's a 30,000-head feedyard custom feed lot. A lot of these cattle are owned by customers," Kraeger said. .
High-value chemicals produced from ethanol feedstocks could boost ...
Biorefineries developed to produce ethanol from cellulose sources such as trees and fast-growing plants could get a significant economic boost from the sale of high-value chemicals such as vanillin flavoring that could be generated from the same feedstock. Revenue from these "side stream" chemicals could help make ethanol produced by biorefineries cost competitive with traditional fossil fuels. At the 232nd national meeting of the American Chemical Society, a researcher from the Georgia Institute of Technology will describe green chemical processes that could produce chemicals worth up to $25 per pound from the same feedstock used to produce ethanol. The presentation will be part of a session "Green Chemistry for Fuel Synthesis and Processing" held Sunday, September 10. "It seems unlikely that fuel from a biorefinery at least in the beginning is going to be as cost-effective as fuel from traditional fossil sources," said Charles Eckert, a professor in the Georgia Tech School of Chemical and Biomolecular Engineering.
Pulp mill may find salvation in ethanol
ABERDEEN -- Community leaders aren't giving up on saving the Weyerhaeuser pulp mill in Cosmopolis from closure, but they are starting to think outside the box. For example, what if, instead of producing cellulose needed for cigarette filters, the mill was converted to create ethanol? According to a feasibility report funded by the Governor's Office, the process to create ethanol at the mill is not only possible, but the technology is available to make it probable. "I'm pitching the sale of the mill every day," says Roy Nott, the president of Paneltech in Hoquiam, who led the team responsible for the feasibility report. "I have people interested in the possibility of ethanol production, but no takers yet." Ethanol can be used as a solvent in colognes, cleaning solutions and even medicine, though lately, it's been in the news more for its potential as a renewable clean-burning additive to gasoline.
