About the research project

Research into alternatives to fossil fuels for commodity feedstocks has accelerated in recent years as we drive to reduce our reliance on non-sustainable resources.  Plant -based biomass is a potential renewable carbon feedstock for commodity chemicals for industrial applications.  Many processes for transforming biomass have been known for decades but the problem lies in that wood-fibre needs pre-processing to be suitable for these applications.  This includes pre-treatment with organic solvents or reagents to separate the lignan from the cellulose prior to further transformation of both of these biomass streams.  Recently we have been developing pressurised hot water extraction as an alternative to organic solvents for the extraction of natural products.  Preliminary experiments have demonstrated potential for this method as a pre-treatment of wood-fibre.  As an example, lignan needs to be removed from the cellulose before it could be into enzymatically converted to glucose and then further through to ethanol, both valuable commodity chemicals.  As the lignin is not chemically modified, unlike most other processes (ie. Kraft bleaching), it can then be processed separately either through pyrolysis to generate biofuel or other processes.  The project will investigate pressurised hot water extraction as a method for pre-treatment of wood-fibre from Eucalyptus Nitens and other plantation species towards lignin and cellulose as renewable sources for commodity chemicals.
