Biomass Pretreatment And Fractionation

Based on our bioprocessing and compositional expertise, we have a very good understanding of how to optimise biomass pretreatment processes. For our clients we have analysed hundreds of samples of outputs from biomass pretreatment processes. We have a very strong understanding of the chemistry of biomass and how to evaluate the conversion and valorisation of the main constituents of lignocellulosic biomass (cellulose, hemicellulose, and lignin). We target mass-closure in our analysis so that the full mechanisms of conversion can be understood and we have a suite of analytical methods to characterise process liquids for monomers, oligomers, sugar degradation products, and fermentability. Our CBE project UNRAVEL concerns the development of a pretreatment process and Celignis plays a key role in the project regarding the analysis of the products of pre-treatment and by investigating the influence of extractives in biomass pretreatment. In our completed BBI project BIOrescue we also analysed the solid and liquid outputs of biomass pretreatment and developed rapid analysis models for them using near infrared spectroscopy.

Our pre-treatment/fractionation expertise is particularly relevant to the following topics of the 2022 CBE-JU Work Programme: JU-CBE-2022-R-01 (High performance bio-based polymers for market applications with stringent requirements), JU-CBE-2022-R-02 (Bio-based coatings, barriers, binders, and adhesives), and JU-CBE-2022-R-05 (Sustainable fibres biorefineries feedstock).
