Abstract
LignoFibre (LGF) organosolv process is a potential novel
fractionation method for biomass, yielding cellulose,
lignin and hemicelluloses. Depending on the solvent used,
the LGF fractions have potential in numerous biomaterial
and chemical applications. Unbleached acetic acid LGF
cellulose fibres showed promising results as
reinforcement fibres in composites, while bleached fibres
could be used for dissolving pulps and cellulose
derivatives as well as for
nanocellulose manufacturing. Ethanol LGF pulps are
suitable material for enzymatic hydrolysis and further
fermentation of the monomeric sugars into bioethanol.
Based on its material properties, sulphur-free LGF lignin
has potential as an additive in bioplastics or in resin
applications. The sugar-based compounds could serve as
platform chemicals and studies on their recovery from the
cooking liquor at high yield and purity are currently
on-going.
