Integrated Biorefinery to Produce Ethanol, High Value Polymers, and Chemicals from Lignocellulosic Biomass

This project is based on the total utilization of the carbon source present in plant cell wall towards fuels and value-added products. The primary objectives of this project are to: (1) Maximize total accessible fermentable sugars from woody biomass by employing CELF pretreatment to produce a cellulose-rich solid and hydrolyze hemicellulose and depolymerize, and dissolve lignin into a concentrated liquid. (2) Achieve >60 g/L ethanol concentration by simultaneous saccharification and fermentation (SSF) of the cellulose-rich material at lower enzyme dosages. (3) Recover and fractionate CELF lignin for chemical and physical characterization to define the most efficient valorization pathways. (4) Synthesize high-value polyurethane films and lignin nanoparticles from the high quality CELF lignin. (5) Develop and apply computer process models to the experimental data from pretreatment, fermentation, and lignin processing to estimate the economic and environmental impact of the integrated process.
