Lignin valorization: Status, challenges and opportunities

Sivasamy Sethupathy et al.

Summary: As an abundant aromatic biopolymer, lignin holds great potential for producing various chemicals and biofuels through biorefinery activities, contributing to a sustainable circular economy. However, lignin valorization faces challenges such as its heterogeneous nature, intrinsic recalcitrance, strong smell, dark color, difficulties in lignocellulosic fractionation, and high bond dissociation enthalpies in its functional groups. Despite these constraints, recent research and development have shown promising applications of lignin-based hydrogels, surfactants, 3D printing materials, electrodes, and fine chemicals production. This review summarizes the main limitations and possible solutions for industrial lignin valorization, and provides future perspectives based on its abundance and potential applications reported in scientific literature.

Fractionation of Lignin Streams Using Tangential Flow Filtration

Jipeng Yan et al.

Summary: Fractionation of lignin using TFF was studied, and the effects of different membrane pore sizes on lignin molecular weight, sugar distribution, viscosity, and lignin functional groups were investigated. The results showed that TFF could effectively separate low-molecular-weight lignin from the aqueous stream.

Green solvents-based molecular weight controllable fractionation process for industrial alkali lignin at room temperature

Huiqi Jin et al.

Summary: A green solvent system was developed for the molecular weight-controllable fractionation of industrial alkali lignin. The fractionation process, achieved by adjusting the ratio of water, ethanol, and gamma-Valerolactone, resulted in six levels of lignin with stepwise controllable molecular weight. The fractionation was confirmed to be a physical process without altering the chemical structure of lignin. The fractionated lignin with higher molecular weight exhibited narrower polydispersity and the fractionated lignin with lower molecular weight had higher content of hydroxyl and carboxyl groups, which could enhance its chemical reactivity in downstream applications.

Hardwood and softwood lignins from sulfite liquors: Structural characterization and valorization through depolymerization

Filipa M. Casimiro et al.

Summary: This study evaluated the structural characteristics of lignins obtained from hardwood and softwood sulfite liquors and studied their oxidative depolymerization process. The results showed that lignin could be used as a raw material to produce high-value products such as vanillin and syringaldehyde.

Fractionation of lignin using organic solvents: A combined experimental and theoretical study

Veerapandian Ponnuchamy et al.

Summary: The study investigated the single-step fractionation of industrial hardwood kraft lignin using different polarity organic solvents. The experimental results showed that higher polarity solvents such as ethanol and acetone had higher solubility yield. Density functional theory (DFT) results indicated that ethanol had the highest interaction energy, followed by acetone, diethyl ether, and hexane.

2G waste lignin to fuel and high value-added chemicals: Approaches, challenges and future outlook for sustainable development

P. Sivagurunathan et al.

Summary: This critical review discusses the isolation and transformation of lignin into value-added chemicals and materials for the economic viability of current biorefineries. It covers the chemical structure of lignocellulosic biomass/lignin, worldwide availability of lignin, and various thermochemical and biotechnological developments for the production of bio-based low molecular weight phenolics. Additionally, functional chemicals applications and challenges, opportunities, and prospects related to lignin valorization are examined.
