The production of lignin nanoparticles (LNPs) has opened new routes to the utilization in advanced applications. existing challenge, however, is develop a method that can easily be adapted on an industrial scale. In this study, we demonstrated green and rapid preparing LNPs directly from sulfur-free alkaline pulping liquor by combining acid precipitation ultrasonication. combined produced spherical LNPs, with hierarchical nanostructure highly negative surface charge, within only 5 min sonication. mild, sonication was achieved sonicating without prior drying acid-precipitated dialyzed lignin. Optimization revealed potential for minimizing consumption, shortening dialysis time, processing as much 20 wt % isolated were stable during storage 180 days, at pH range 4–7, dispersing medium below 0.1 M NaCl. also displayed excellent emulsifying properties, stabilizing oil-in-water emulsions. Thus, simple energy-efficient opens sustainable, straightforward, scalable route organic solvent-free high interface stabilizers multiphase systems food medical industries.

Lignin is a primary component of lignocellulosic biomass and an underutilized feedstock in the growing pulping biofuel industries. Currently, over 50 million tons industrial lignin are produced annually from bioethanol processes world. Around 95 % burned as fuel heat power plants due to its complicated, destructive, condensed structures hindering direct utilization, while remaining 5 used for potential applications, such additives, binders, dispersants, surfactants, through modification. Meanwhile, different biorefinery also produce considerable amount with various structural features properties. The development technologies characterization currently desirable valorization, which will improve techno-economics applications lignins

In the past 70 years, over 8 billion tons of plastics have been produced, majority which cannot be fully biodegraded, causing their fragments to found everywhere in biosphere, including living organisms. Herein, a group biodegradable composites were produced by blending poly(butylene adipate-co-terephthalate) (PBAT) with technical lignin through twin-screw extrusion method. Two strategies developed improve mechanical properties PBAT/lignin composites: (1) modifying via methylation reduce hydrogen bonding between −OH groups and (2) enhancing intermolecular interactions PBAT adding maleic anhydride-graft-PBAT as compatibilizer. The obtained from two 60 wt % contents exhibited ideal tensile performance could meet requirement Chinese National Standard for packaging. different composite components investigated morphological thermal analyses. results showed that when is used filler composites, molecular mobility size its agglomerates remarkably impacted ductility strength films. A simple cost comparison neat film films indicated latter was economically competitive, production costs significantly 36%.
