Iowa Plant Breaks Ground on Bolt-On Cellulosic Process

By Staff | September 23, 2013

Galva-Iowa-based Quad County Corn Processors recently held a groundbreaking ceremony for a new bolt-on cellulosic technology that will allow the 35 MMgy corn-ethanol plant to produce 2 MMgy of cellulosic ethanol.  Construction on the $8.5 million cellulosic addition is expected to be complete by April 2014. 

The patent-pending cellulosic process, Adding Cellulosic Ethanol, was a project Travis Brotherson, plant engineer, worked on for the past four years. Two years ago the company started working to take the process from pilot-and demonstration-scale to a full-scale installation at the plant, said General Manager Delayne Johnson. 

According to Johnson, the production process starts with the traditional grain-based fermentation process, followed by a trip through the bolt-on facility, where another round of fermentation produces cellulosic ethanol from corn kernel fiber. The ACE technology is expected to increase ethanol yield by 6 percent and boost corn oil extraction by approximately 300 percent.
