Abstract: | The US government is encouraging increased production and use of gasohol in an effort to make the United States more energy independent. The current national goal is to substitute gasohol for 10% of the unleaded gasoline consumed in the United States by th end of 1980. Increased production of fuel ethanol in the years to come seems certain. In producing fuel ethanol (200 proof) from biomass feedstocks by fermentation, a liquid residue called stillage is produced. The concentration of BOD/sub 5/ in stillage is usually high compared to that in domestic waste, and this residue must go through a waste treatment process before discharge into bodies of water. While stillage has potential uses as an animal feed, soil amendment, and protein source for humans, the liquid remaining after useful stillage components have been extracted must still be treated before discharge to the environment. This paper identifies the types of stillage that are produced as well as their control. The concept of stillage control in the context of this paper includes both the uses and environmental control technology needs of stillage. |
