Project Liberty: Launch of an Integrated Bio-Refinery with Eco-Sustainable and Renewable Technologies. Conversion of Corn Stover Biomass to Bio-Ethanol, Final Report
- POET-DSM Project Liberty, LLC, Emmetsburg, IA (United States)
POET-DSM Advanced Biofuels, in collaboration with parent companies, POET and DSM, has successfully designed, constructed, and continuously operated Project Liberty, a 770 bone-dry ton per day (tpd) nameplate capacity, 20 million gallon (cellulosic bioethanol) per year demonstration scale integrated biorefinery (IBR). The IBR produced cellulosic bio-ethanol from agriculture waste (corn stover) feedstock using next-generation pretreatment and enzymatic conversion technologies. The IBR plant was built and demonstrated operations in Emmetsburg, Iowa. The schedule for this IBR project is illustrated in Figure E1. Due to uncontrollable market factors and COVID-19 pandemic, cellulosic bioethanol production ceased near the end of 2019 and remaining operations were idled June of 2020.
