TLDR
This work proposes a biomass conversion strategy that maximizes the conversion of lignocellulosic biomass into high-value products that can be commercialized, providing the opportunity for successful translation to an economically viable commercial process.Abstract:
The production of renewable chemicals and biofuels must be cost- and performance- competitive with petroleum-derived equivalents to be widely accepted by markets and society We propose a biomass conversion strategy that maximizes the conversion of lignocellulosic biomass (up to 80% of the biomass to useful products) into high-value products that can be commercialized, providing the opportunity for successful translation to an economically viable commercial process Our fractionation method preserves the value of all three primary components: (i) cellulose, which is converted into dissolving pulp for fibers and chemicals production; (ii) hemicellulose, which is converted into furfural (a building block chemical); and (iii) lignin, which is converted into carbon products (carbon foam, fibers, or battery anodes), together producing revenues of more than $500 per dry metric ton of biomass Once de-risked, our technology can be extended to produce other renewable chemicals and biofuelsread more

TL;DR: This work converted levulinic acid (LA), an established degradation product of lignocellulosic biomass, to butanone (a.k.a. methyl-ethyl ketone - MEK), a widely used industrial solvent, by feeding cells a non-sugar substrate, by-passing central metabolism, and linking a key metabolic step to generation of acetyl-CoA that is required for biomass and energy generation.

Integrated strategy for coproducing bioethanol and adipic acid from lignocellulosic biomass
TL;DR: In this paper, a biorefinery process is developed to coproduce ethanol as a renewable fuel and adipic acid as a value-added product, and the developed experimental-based process model is used to evaluate the economic feasibility and environmental impact of the integrated coproduction strategy.
