Lignin is the second most abundant biopolymer on planet. It a biocompatible, cheap, environmentally friendly and readily accessible material. has been reported that these biomacromolecules have antimicrobial activities. Consequently, lignin (LIG) potential to be used for biomedical applications. In present work, simple method prepare lignin-based hydrogels described. The were prepared by combining LIG with poly(ethylene glycol) poly(methyl vinyl ether-co-maleic acid) through an...
Biopolymers from forestry biomass are promising for the sustainable development of new biobased materials. As such, lignin and fiber-based biocomposites plausible renewable alternatives to petrochemical-based products. In this study, we have obtained Spruce through a soda pulping process. The was used manufacturing biocomposite filaments containing 20% 40% using polylactic acid (PLA) as matrix material. Dogbones mechanical testing were 3D printed by fused deposition modelling. corresponding...
Technical lignins are structurally heterogeneous and polydisperse. This work describes the use of a simple green method for lignin fractionation, using different proportions acetone (40 60%) in water. Lignins from three sources (wheat straw organosolv lignin, wheat soda softwood kraft lignin) were used this fractionation protocol. The obtained fractions showed molar mass functional groups. lower more phenolic hydroxyl groups carboxylic acid moieties than higher fractions, which also...
Olea europaea L. leaves constitute a source of bioactive compounds with recognized benefits for both human health and technological purposes. In the present work, different extracts from olive were obtained by application two extraction methods, Soxhlet microwave-assisted (MAE), six solvents (distilled water, ethanolic glycerol mixtures solvents). MAE was applied under 40, 60 80 °C 3, 6.5 10 min. The effect method, solvent treatment factors (the latter in MAE) on total phenol content (TPC),...
Water pollution is one of the most serious problems worldwide. Nanocellulose-based aerogels usually show excellent adsorption capacities due to their high aspect ratio, specific surface area and charge, making them ideal for water purification. In this work, (ligno)cellulose nanofibers (LCNFs/CNFs) from wheat straw residues were obtained using two types pre-treatments: mechanical (Mec) TEMPO-mediated oxidization (TO), obtain different consistency (0.2, 0.4, 0.6 0.8) bioaerogels, as dye...
With the aim of identifying new sources to produce cellulose nanofibers, olive tree pruning biomass (OTPB) was proposed for valorization as a sustainable source cellulose. OTPB subjected soda pulping process purification and facilitate delamination fiber in nanofibrillation process. Unbleached bleached pulp were used study effect lignin production nanofibers through different pretreatments (mechanical TEMPO-mediated oxidation). High-pressure homogenization treatment. It observed that...
A biodegradable packaging film containing cellulose nanofibers from olive tree pruning, a by-product of olives production, was obtained using solvent casting method. Nanocellulose added to polyvinyl alcohol (PVA) enhance the technological properties composite as food material. unbleached and bleached pulp through mechanical TEMPO pretreatment. Crystalline chemical structure, surface microstructure, UV gas barrier, optical, antioxidant properties, well thermal stability were evaluated....
Some agricultural residues such as wheat or barley straw, well certain fast-growing plants like Leucaena leucocephala and Chamaecytisus proliferus, could be used raw materials for the paper industry an alternative to traditional (eucalyptus, pine, etc.). In present study, four types of lignin obtained from spent liquors produced by pulping processes using abovementioned feedstocks were isolated characterized. Lignin samples acquired through acid precipitation these liquors. The...
