[...]... costs in ethanol plants mainly by reducing the labor required, but they have also improved production efficiency in other ways, letting operators fine-tune processes they could not control as closely in the past Better process control also reduces downtime and maintenance 14 New Technologies in Ethanol Production, AER-842 Office of Energy Policy and New Uses, USDA Environmental Technologies In addition... process In speaking of both corn stover and forest product waste, Industrial Bioprocessing writes, “The big stumbling block in manufacturing ethanol from biomass is the cost of hydrolyzing cellulose into fermentable sugar.” To speed the quest for cheaper ways of using enzymes to convert biomass to ethanol, DOE funded research by two commercial enzyme companies, 24 New Technologies in Ethanol Production, ... BBI International Fuel Ethanol: A Technological Evolution Grand Forks, ND: BBI Publishing, June 2004 Rendleman, C Matthew, and Neil Hohmann, “The Impact of Production Innovations in the Fuel Ethanol Industry,” Agribusiness, 9(3):217-31, 1993 Renewable Fuels Association Homegrown for the Homeland: Ethanol Industry Outlook 2005 Washington, DC, February 2005 Ross, Martin “California Ethanol Dream Coming... from the plant.1 New rural ethanol plants also provide employment Though the plants need fewer employees than they would have just a few years ago when the industry was using less labor-saving technology, the U.S Department of Energy (DOE) estimates that ethanol production is responsible for 40,000 jobs and $1.3 billion in increased annual household income 20 New Technologies in Ethanol Production, AER-842... already been discussed in the section “Advances in Separation Techniques.” 13 New Technologies in Ethanol Production, AER-842 Office of Energy Policy and New Uses, USDA Distillation Technology Standard distillation techniques leave about 4-percent water in the final ethanol In the early days of ethanol distillation, the basic production design came from the beverage alcohol industry, where there is... experimenting with membrane technology that would remove phosphorus from the thin stillage (the liquid remaining after removal of the wet distiller’s grains) before it becomes feed The result is likely to be more efficient feed rations and reduced environmental impact 15 New Technologies in Ethanol Production, AER-842 Office of Energy Policy and New Uses, USDA Technologies Involving Coproducts In addition... plants find uses for the gas (Lynn Grooms in BioFuels Journal, 2005b); the other plants, because of the low commercial value of CO2, simply vent it into the air Most CO2 sold commercially is used in soft drinks and food processing, while other uses, such as water treatment, welding, chemical processing, refrigerants, and hydroponics, consume some of the remainder 17 New Technologies in Ethanol Production, ... “Ultimately, if renewable automotive fuel becomes economical in the United States it will have to be made from lignocellulosic biomass” (Industrial Bioprocessing) In the end, biomass-to -ethanol production may be attractive because biomass would cost less than corn In addition, selling the feed coproducts from corn ethanol may become burdensome As corn ethanol production increases, an inevitable result... useful in reducing cholesterol A biorefinery may also yield purified proteins used as human food or in industrial processes A potentially recoverable coproduct is zein, a corn protein that can be used in adhesives and in coatings for pharmaceuticals and packaging materials because of its good water-vapor barrier properties ARS scientists are working to develop a cost-effective way to recover zein from... Potential In keeping with USDA’s early estimates of the savings to come, the cost of ethanol production has indeed fallen Though improvements in process optimization and technology have been important, the fluctuating prices of inputs such as corn, the price of energy alternatives, and even environmental developments such as a drop in MTBE use, play larger roles in the fortunes of the industry Ethanol production . 1). 2 New Technologies in Ethanol Production, AER-842 Office of Energy Policy and New Uses, USDA Changes Since the 1993 ERS Analysis of Ethanol Production In. impact of producing ethanol. In this report, we examine various production technologies, beginning with input improve- ments and then discussing process improvements,
