Co-solvent System for Sugar Production from Lignocellulosic Biomass Using Biomass Derived γ-valerolactone
Objective To improve ease-of-use and economics of the GVL method for lignocellulose biomass deconstruction.
Approach
The GVL method is a promising biomass-agnostic, renewable technology that can improve the economics of biofuel production
Recovery of sugars and lignin from the GVL mixture relies on methods that are expensive or may inhibit downstream conversion of sugars to biofuels; a new method examined the use of co-solvents1 and their impact on sugar yield and economics of biofuel production2
Result/Impacts
Use of co-solvents to recover high-yielding sugar streams, lignin, and GVL is comparable to previously used recovery methods
Technoeconomic analysis for ethanol production indicated a minimum selling price of $2.95 per gasoline gallon equivalent, a ~10-12% decrease when compared to other benchmarked processes
