Lignin constitutes between 15 and 30% of all lignocellulosic biomass, and is generally obtained from biomass treatment, as a byproduct in pulp and paper processing or as a residue in any bio-ethanol production process. Lignin can be combusted to provide heat and/or power; however, increasing the value of this residue by converting it to higher value materials can significantly enhance the sustainable exploitation of natural resources and competitiveness of biomass based-technologies.
