“…The issues with complicated processing and functionalization of lignin due to its heterogeneous nature are still the major challenges to be surmounted for its commercial use. Despite that, lignin-based polymer resins are still prominent materials to be used both in well-known and emerging fields, such as adhesives, [28] flame retardants, 3D-printing resins, food packaging, supercapacitor electrode materials, [29] bio-based road materials, [30] foams, [31] etc. [5,6c,26-27] The main types of cross-linking reactions utilized in lignin-based resin formulations are explained in table 1.…”

Lignin, a complex and abundant biopolymer derived from plant cell walls, has emerged as a promising feedstock for sustainable material development. Due to the high abundance of phenylpropanoid units, aromatic rings, and hydroxyl groups, lignin is an ideal candidate for being explored in various material applications. Therefore, the demand on lignin valorization for development of value‐added products is significantly increasing. This mini‐review provides an overview of lignin upconversion, focusing on its functionalization through chemical and enzymatic routes, and its application in lignin‐based polymer resins, hydrogels, and nanomaterials. The functionalization of lignin molecules with various chemical groups offers tailored properties and increased compatibility with other materials, expanding its potential applications. Additionally, the formation of lignin‐based networks, either through cross‐linking or blending with polymers, generates novel materials with improved mechanical, thermal, and barrier properties. However, challenges remain in optimizing functionalization techniques, preserving the innate complexity of lignin, and achieving scalability for industrial implementation. As lignin's potential continues to be unlocked, it is poised to contribute significantly to the shift towards more eco‐friendly and resource‐efficient industries

“…Trotzdem sind ligninbasierte Polymerharze nach wie vor wichtige Materialien, die sowohl in bekannten als auch in neu entstehenden Bereichen eingesetzt werden, z. B. als Klebstoffe, [28] Flammschutzmittel, 3D-Druckharze, Lebensmittelverpackungen, Elektrodenmaterialien für Superkondensatoren, [29] biobasierte Straßenbaumaterialien, [30] Schaumstoffe, [31] usw. [5,6c,26-27] Tabelle 1 zeigt die wichtigsten Arten von Vernetzungsreaktionen, die in ligninbasierten Harzformulierungen verwendet werden.…”

“…Scanning Electron Microscope (SEM) and Environmental Scanning Electron Microscope (ESEM) are important techniques for investigating lignin-modified bitumen, as they provide high-resolution images of the surface [24]. Many research studies have been conducted in this area [25][26][27]. For instance, Kalampokis et al (2022) used SEM to investigate the shape and particle size distribution of lignin powder [28].…”

Environmental approaches in the asphalt industry have focused on utilizing waste materials as modifiers. Lignin is a high-potential bitumen modifier due to its characteristics; however, the blending process with bitumen is critical. This study investigates the chemo-thermal characteristics of lignin-modified bitumen under two different blending protocols, including a mechanical and high-shear mixer to evaluate its performance as a modifier. According to the protocols, 5, 10, and 20% of Kraft lignin was added to a PG 58S−28 bitumen. The samples were subjected to analysis using Brookfield Rotational Viscosity (BRV), Dynamic Shear Rheometer (DSR), Fourier-Transform Infrared Spectroscopy (FTIR), Environmental Scanning Electron Microscopy (ESEM), Thermogravimetric Analysis (TGA), and Differential Scanning Calorimetry (DSC) tests. The BRV and DSR test results indicate a remarkable alteration in the rheological properties of lignin-modified bitumen under blending conditions. The FTIR analysis indicated that Kraft lignin did not produce new functional groups. The fibril structures of the bitumens are affected by Kraft lignin content and blending conditions due to ESEM. The Kraft lignin and blending conditions influence the thermal behavior of bitumen. The findings highlight Kraft lignin’s potential as a bitumen modifier, and the fact that its characteristics are influenced by the blending protocol and Kraft lignin content.
