Cereal Process Technologies increases co-product value in ethanol production through fractionation

Cereal Process Technologies completed performance tests of the nation’s largest fractionation plant at Renew Energy’s 130-million-gallon ethanol plant at Jefferson, Wisconsin.  Renew Energy’s facility, which uses Cereal Process Technologies’ innovative fractioning process, proved in sustained testing last week consistent production of high-starch streams into the ethanol plant and the separation and capture of more valuable co-products, including corn germ and corn bran.  The facility also is producing higher-protein stillage, which Renew has trademarked and sells as “Renew Meal.”

Last week in related news, ICM announced its own prospective process to extract more food for human consumption from the ethanol conversion process that uses field corn used for livestock. The process, called Total Kernel Optimization, provids a higher yield in separating oil and protein during conversion, which is used for human consumption in corn syrup and corn oil, while the starch is used for ethanol and the remaining fiber is burned for power generation. ICM said that it will retrofit nine ethanol plants per year commencing in 2009, out of its portfolio of 73 plants in operation and 26 in construction.
