“Generation one is starch to ethanol and generation two is corn stover and grasses but there is cellulose in the corn kernel,” explained ICM, Inc. technical director Scott Kohl during a session last week at the Corn Utilization and Technology Conference. “That’s the Generation 1.5 – the fiber in the corn kernel.”
Kohl says ICM is developing processes to separate that fiber from the rest of the kernel to make more ethanol so that the yield from a single bushel of corn will increase. “We’ve run nearly 2,000 hours of pilot runs on that system,” he said. “We are now in the process of getting the financing arranged to have the first plant running by the middle of 2015.” Kohl says the process will raise the ethanol yield from corn by 10 percent and the distillers protein content will also increase.
At CUTC, Kohl also talked about new products from dry grind mills through ICM’s patent-pending Fiber Separation Technology (FST), which is precursor to the Gen 1.5 process. “In order to get the fiber ready for the Gen 1.5 process we have to separate and purify it,” he said. “With the new process (plants) are going to make ethanol, high protein, high fiber, and a lot more oil.”
