POET-DSM Advanced Biofuels, LLC, is Sioux Falls, South Dakota, United States based collaborative venture of POET, LLC and Royal DSM. The two giants of bioethanol production arena joined hands with the aim to convert corn crop residues into cellulosic ethanol at a cost competitive with corn based bioethanol production. POET has expertise in organizing feedstock, conditioning and its storage. It is among the world’s largest ethanol producers and owns 27 corn grain based ethanol production plants. DSM has expertise in scaling up the industrial and biotechnological operations. Their proprietary yeast strains and enzymes are able to convert cellulosic biomass into ethanol with co-fermentation of the C6 and C5 sugars.
Project LIBERTY: Cellulosic Ethanol from Corn Residues
Project LIBERTY is the first commercial scale cellulosic ethanol production plant of POET-DSM Advanced Biofuels. The project aims to license the integrated technology package for the conversion of corn crop residues to cellulosic ethanol globally.
The plant shares the infrastructure with the adjacent 50MMgy POET biorefining Emmetsburg, Iowa and is already operationals since Sept , 2014. It can process 770 tons of corn cobs, leaves, husk and stalk daily to produce 20 million gallons of ethanol per year. The production capacity will later be escalated to approximately 25 million gallons per year. From the plant the energy is also generated as co-product of the bio-ethanol production process. It is planned to be used to power LIBERTY and the excess will be used in adjoining corn grain-based bioethanol plant.
The project was awarded $100 million by U.S. Department of Energy and $20 million financial assistance by The State of Iowa.
