Life cycle analysis of hybrid poplar trees for cellulosic ethanol
… hybrid poplars as a biomass crop for cellulosic ethanol. A "Life Cycle Assessment" (LCA) methodology is used to systematically evaluate the hybrid poplar's energy input and output as well as greenhouse gas (GHG) emissions. The system boundary is divided into three sections, agriculture, …

Effects of compositional variables on fouling behavior of thin stillage
In the US, ethanol is produced primarily from corn. There are two major commercial processes: corn wet milling (CWM) and dry grind corn (DGC). The DGC industry has grown and made 86% of corn ethanol by the end of 2008. During DGC processing, after distillation, the remaining nonfermentable material …

Characterization of zein extracted from beer solids, a coproduct of dry-grind ethanol
… spreading and viability. Coproducts of corn-to-ethanol processing remain potential sources of zein. Distillers’ wet grains (DWG) a coproduct of dry grind ethanol contain about 40% (db) protein, where 50% of the protein is zein. Attempts to extract zein from coproducts have been limited to …

Protease Use In Ethanol Production From Dry Fractionated Corn
… endosperm from germ and pericarp improves corn ethanol processing by increasing fermentation throughput and generating salable coproducts. One such technology, dry fractionation, suffers from loss of germ derived nutrients and amino acids, resulting in poor fermentation kinetics. In the fuel …

Experimental and Modeling the Flow Properties of Distillers Dried Grains (DDG) with Varying Soluble Levels and Moisture Contents
… corn residues obtained from dry grind ethanol processing. It is rich in proteins, fat, vitamins, and minerals. It is an excellent source of digestible protein for ruminants and non-ruminants. It is a valuable feed ingredient for livestock ration, improves the palatability and also …
