POET-DSM Ramping Up Cellulosic Ethanol Production
May 3, 2016 - Issue #216View Full Issue
POET-DSM Advanced Biofuels recently announced, while it has already produced several tank car loads of cellulosic ethanol, it is now in the “ramp-up” phase to reach its full 20 million gallons per year capacity at Project Liberty in Emmetsburg, Iowa.
Last year’s “startup” phase yielded great experience that will benefit subsequent plants and the learning continues each day as POET-DSM Advanced Biofuels works to make cellulosic ethanol in the most efficient way possible.
POET-DSM’s process uses corn cobs, leaves, husk and some stalk as the feedstock for cellulosic ethanol. This product is harvested by local farmers and brought to the plant for processing. Besides ethanol, Project LIBERTY produces biogas from its anaerobic digester and steam from its solid-fuel boiler to produce power to run its own processes and export energy to the adjacent grain-based ethanol plant.
