Green Solvents in Biomass Delignification for Fuels and Chemicals

BioResources, 2023
Lignin is considered by many as the ultimate barrier that impedes biomass conversion to fuels and chemicals. Several delignification strategies have been developed so far, but alkaline extraction remains the most widely used. However, this technology has

Pengaruh Kondisi Proses Terhadap Yield dan Kadar Lignin Pulp dari Pelepah Sawit dengan Proses Asam Formiat

Jurnal Rekayasa Kimia & Lingkungan, 2012
Formic acid pulping of oil palm frond was conducted to study the influence of process variables (formic acid concentration, hydrogen peroxide concentration, and pulping time) on the properties of pulp produced (yield pulp and lignin content).

Integrated biorefinery for cellulosic ethanol and spherical nanolignin production from coconut waste

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Green coconut waste was subjected to different fractionation methods to obtain integrated lignin nanoparticles and cellulosic ethanol. Pretreatment with gradual addition of dilute sulfuric acid provided a higher structural hemicellulose precursor yield (68.2%).

A brief review of the structure and extraction methods of lignin

Sustainable Chemistry for the Environment
One of the three basic components of lignocellulosic biomass (LB), lignin is the second most plenty of natural polymer on the planet after cellulose. It has the power to become the aromatic raw material of the future for industry. However, this potential

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Organosolv pulping-VII: Delignification selectivity of formic acid pulping of Eucalyptus grandis

Bioresource Technology, 1994
Abstract Eucalyptus grandis wood was ca. 80% delignified in 79–92% (v v −1 formic acid containing 0.22% (w v −1 ) HCl as a catalyst under reflux and mechanical stirring for 90 min. Pulps obtained under these conditions presented pulp yield, Kappa number and Klason lignin in the ranges of 44–52%, 30–40 and 8–10%, respectively. The presence of water

Almond Shell‐Derived Cellulosic Microfibres: Extraction, Characterisation and Applications in Sustainable Paper‐Based Packaging

Packaging Technology and Science, Volume 39, Issue 10, Page 1231-1251, October 2026.
Cellulosic microfibres were extracted from almond shells using organosolv, soda and kraft processes, and comprehensive physicochemical, surface, thermal and morphological characterisation demonstrated their strong potential as sustainable fillers for paper‐based packaging application. ABSTRACT This study develops pathways for the valorisation of almond

Toward Plastic‐Free Vineyards: The Role of Bioplastics in Sustainable Viticulture—A Review

Polymers for Advanced Technologies, Volume 37, Issue 9, September 2026.
ABSTRACT Agricultural value chains consume more than 12.5 Mt. of plastics annually, and vineyard systems are a notable source of short‐lived plastic waste. In viticulture, conventional plastics improve agricultural efficiency, crop protection, and wine quality, but their widespread use raises environmental and health concerns.
