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...
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....
As a transition strategy towards sustainability, food packaging plays crucial role in the current era. This, carried out biorefinery context of agricultural residues, involves not only obtaining desirable products but comprehensive utilization biomass that contributes to circular bioeconomy. The present work proposes preparation bioactive absorbent pads through multi-product approach from bay tree pruning waste (BTPW). In first step, chitosan aerogels reinforced with lignocellulose and...
This work evaluates the preparedness of packaging industry towards more circular, sustainable solutions for fresh meat and fish. The term bioplastic is ill-defined, creating confusion between all stakeholders in value chain. implementation as food contact material will only occur when there are demonstrated that can equally or better protect fish from spoilage, compared to conventional plastic. Price, supply chain availability, machinability, safety also be key shift fossil bioplastic....
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...
2,2,6,6-tetramethylpyperidine-1-oxyl (TEMPO) oxidized cellulose nanofibrils (CNF) were used as ink for three-dimensional (3D) printing of porous structures with potential wound dressings. Alginate (10, 20, 30 and 40 wt%) was incorporated into the formulation to facilitate ionic cross-linking calcium chloride (CaCl2). The effect two different concentrations CaCl2 (50 100 mM) studied. 3D printed hydrogels freeze-dried produce aerogels which tested water absorption. Scanning Electronic...
Abstract The extensive use of non‐biodegradable bioplastics and fossil‐based plastics in food packaging presents a significant environmental challenge. Consequently, there has been growing interest exploring agricultural biomass as potential source for formulating biocomposites due to the substantial amount lignocellulosic residue generated. This study explores utilization avocado pruning (APR) isolating lignocellulose fibers their application replacement reinforcement material bio‐based...
