Obtaining Nanolignin from Green Coconut Shell and Fiber by the Acetosolv Method with Subsequent Ultrasonication

Reactions, Год журнала: 2025, Номер 6(1), С. 7 - 7

Опубликована: Янв. 11, 2025

This work aimed to extract nanolignin from green coconut husk and fiber using the acetosolv method, with aim of transforming waste into high-value-added products promoting sustainability bioeconomy. The pulping was carried out in two stages, varying temperature conditions presence or absence extractives. Lignin obtained by precipitation subsequently characterized through chemical morphological analyses. analyses primary components demonstrated lignin, cellulose, hemicellulose contents 40%, 15.90%, 15.86%, respectively. Then, produced ultrasonication (850 W for 10 20 min). characteristics were analyzed, considering influence temperatures (100 °C 120 °C) need a pretreatment step (removal extractives). variation between 100 °C, as well extractives, did not significantly lignin quality extraction efficiency. under this condition subjected DLS technique determine hydrodynamic diameter polydispersity nanoparticles obtained, an average 533.75 ± 15.12 nm after min ultrasonication. purity confirmed such Klason ash content, which presented values 78.82 0.81% 0.55 0.26%, FTIR revealed typical characteristics, ketone groups, aromatic structures, methoxylation, while thermograms thermal stability lignin. Acetosolv proved be particularly interesting, preserving good allowing partial recovery solvents used, energy efficiency process.

Techno-economic Assessment of the Industrial-Scale Production of Epoxidized Kraft Lignin for Adhesives or Coatings

ACS Sustainable Chemistry & Engineering, Год журнала: 2025, Номер unknown

Опубликована: Фев. 17, 2025

Lignin is an abundantly available biopolymer and as such has emerging potential for utilization in value-added applications. The designed industrial-scale process utilizes equipment that currently use on industrial scale, which favors the scale-up of process. A novel model Aspen Plus provides mass energy balances production main processing steps are lignin solution preparation, epoxidation reaction, solvent separation, recycling, product recovery. itself produces a negligible amount waste no greenhouse gas emissions. emissions utility depend source fall close to zero if green used. recycling rates unreacted solvents over 99%, it possible biobased Efficient key parameter profitability minimum selling price epoxidized kraft was estimated 0.68 €/kg when produced plant integrated with existing pulp mill or biorefinery. This research shows technically economically feasible current adhesive coatings markets.
