Lignin Biorefinery Approach using Electrochemical Flow

LIBERATE will deliver a pilot-scale electrochemical plant to demonstrate the commercial opportunities of converting low-cost lignin feedstock into high value biosustainable chemicals. The LIBERATE project will model and physically
integrate renewable energy sources to deliver a process that is capable of synthesizing chemicals with zero carbon dioxide. The renewable energy integration will open up new business models for biorefinery operators to utilize peak renewable energy at discounted rates.

The project will deliver the following benefits:

  • An electrochemical depolymerisation of kraft lignin to synthesize vanillin with a 7% yield

  • An electrochemical depolymerisation of organosolv lignin to synthesize mixed oligomers which can be converted into phenolic derivatives, with a yield of >35%

  • An electrochemical oxidation of biosustainable cyclohexanol to synthesize propyladipic acid with a yield of up to 80%

  • A biorefinery process capable of accommodating renewable energy fluctuations without loss in efficiency

  • A biorefinery process that exhibits a 95% improvement in the energy efficiency of the process

  • A biorefinery process that exhibits a 350% improvement in resource efficiency

  • A biorefinery process that is capable of producing 29 times less carbon dioxide than the conventional petrochemical alternatives
