Biomass fractionation and modification

One of the main challenges related to utilisation of lignocellulosic components is the recalcitrant structure of lignocellulose in plants and the drawbacks of current fractionation technologies that are energy-intensive, non-green, non-selective and do not preserve the “natural” structure of the main components.

We aim to discover novel solvents and multiphase systems capable of isolating or dissolving lignin and hemicellulose from lignocellulosic biomass and elucidate their mode of action. We aim to produce lignocellulose-based building blocks of uniform quality with respect to chemistry and morphology by uncovering the disassembly and reassembly mechanisms. Furthermore we will propose new methods for modification building blocks.

Project examples:

  • In situ modification of biomass components during fractionation based on molecular oxygen redox chemistry
  • Fundamentals of γ-valerolactone – Biorefinery of birch wood
  • Enzymatic modification of the lignocellulosic building blocks
