Lignin, the term commonly used in literature, represents a group of heterogeneous aromatic
compounds of plant origin. Protolignin or lignin in the cell wall is entirely different from the …

Organosolv treatment is among the most promising strategies for valorising lignocellulosic
biomass and could facilitate the transition towards enhanced utilization of renewable …

Technical lignins are bulk feedstocks. They are generated as byproducts from pulping or
cellulosic ethanol production. As lignin undergoes significant structural changes as a result …

This tutorial review aims to describe the status of the scaling up of organosolv treatment. It is
a process where various lignocellulosic materials are fractionated, selective …

Acetone organosolv fractionation of beech and birch wood at the lab-scale results in high
sugar yields from the (hemi) cellulose and the isolation of a high-purity lignin. In this study …

Lignin valorization is significantly hindered by the intrinsic heterogeneity of its complex
structures and variability of biomass feedstocks. Fractionation of lignin can overcome these …

When optimizing the process parameters of the acidic ethanolic organosolv process, the aim
is usually to maximize the delignification and/or lignin purity. However, process parameters …

Lignin holds the potential to obtain key monoaromatic compounds upon its
depolymerization. Depolymerization of woody biomass by pyrolysis is well established but …

Organosolv processes provide access to less degraded and higher purity lignins. However,
these are rarely applied to softwood species with high lignin contents and complex …

Eucalyptus sawdust is a residue from the pulp industry, currently used for energy production.
Organosolv and autohydrolysis pretreatments for integrated valorization of this residue …
