Abstract This study explores the use of black soldier fly larvae protein as a bio-based adhesive to produce particleboards from sugarcane bagasse. A comprehensive evaluation was conducted, including rheological characterization of the adhesive and physical–mechanical testing of the panels according to European standards. The black soldier fly larvae-based adhesive exhibited gel-like viscoelastic behavior, rapid partial structural recovery after shear, and favorable application properties. Particleboards manufactured with this adhesive and sugarcane bagasse achieved promising mechanical performance, with modulus of rupture and modulus of elasticity values of 30.2 and 3500 MPa, respectively. Internal bond strength exceeded 0.4 MPa,… More > Graphic Abstract

Abstract The aim of this research was to synthesize a new totally bio wood adhesive entailing the use of oxidized starch (OST), urea, and oxidized lignin (OL). For this reason, non-modified (L) and oxidized lignin (OL) at different contents (20%, 30%, and 40%) were used to prepare the starch-urea-lignin (SUL) and starch-urea-oxidized lignin (SUOL) resin. Sodium persulfate (SPS) as oxidizer was employed to oxidize both starch and lignin. Urea was just used as a low cost and effective crosslinker in the resin composition. The properties of the synthesized resins and the plywood panels bonded with them… More > Graphic Abstract

Abstract The increasing demand for renewable energy sources has driven the exploration of innovative materials for biofuel production. This study investigates bio-pellet characteristics derived from several oyster mushroom baglog wastes with varying concentrations of molasses as an adhesive. The process began with sun-drying the baglog waste for three days, followed by oven drying at 80°C for 24 h. Bio-pellets were produced by blending baglog waste with molasses at concentrations of 5% and 10% (w/v), then subsequently fed into a pellet mill. The bio-pellets were left to rest for one hour before analysis. The quality of bio-pellets… More > Graphic Abstract

Abstract The increase in wood and wood-based products in the construction and furniture sectors has grown exponentially, generating severe environmental and socioeconomic impacts. Particleboard panels have been the main cost-benefit option on the market due to their lightness and lower cost compared to solid wood. However, the synthetic adhesives used in producing traditional particleboard panels cause serious harm to human health. Developing particleboard panels with fibrous waste and natural adhesives could be a sustainable alternative for these sectors. The work aimed to create particleboards with fibrous wastes from the pseudostem of the banana tree (Musa paradisiaca) and… More > Graphic Abstract

Abstract As the most abundant aromatic bio-based polymer, lignin has great potential as a sustainable feedstock for building crosslinked thermoset polymers as bio-based adhesives. However, the potential of hardwood kraft lignin (HKL) is limited due to its poor crosslinking reactivity. Hence, for the first time, the present study reports the facile oxidation of HKL involving a redox reaction with silver-ammonia complexes ([(AgNH₃)₂]⁺), primarily focusing on oxidation to produce reactive quinones and promote C–C linkages during reaction. This study aims to increases reactivity of oxidized HKL for effective crosslinking with monoethanolamine (MEA) for the development of bio-based wood… More > Graphic Abstract

Abstract The main raw material utilized in wood adhesives comes from petrochemical extractives. However, due to the excessive dependence on petrochemical resources and the adverse impact on the ecosystem and human well-being, there is an increasing trend to develop byproduct protein-based adhesives in the current global food safety context. In this research, flaxseed meal was subjected to pretreatment, and trimethylolpropane triglycidyl ether (TTE) and ethylenediamine (EN) were utilized as crosslinkers to establish a more compact adhesive layer and to prevent water intrusion. The pretreatment decreased the FM/UB viscosity by 60% compared to FM. The combination… More > Graphic Abstract

Abstract This research aims to investigate efficient repair techniques of cracked Ti-alloy aircraft structures with adhesively bonded carbon fiber-reinforced polymer composite patches. The repaired specimens in the configuration of a Ti-alloy butt joint with one-side bonded composite patch were prepared under multiple repair factors including patch thickness, patch length, adhesive thickness, cure pressure, patch layup and surface treatment. The repair efficiency was evaluated by loading behavior, bonded interface microstructure and failure mode. The three-dimensional (3D) finite element (FE) model has been established. Based on 3D Hashin failure criteria, the damage initiation and evolution in CFRP were… More >

Abstract Over the last decade, the oriented strand board (OSB) market presented meaningful growth. However, as a wood-based product, because of its anatomical structure and chemical composition, OSB can be damaged by biodeterioration agents. Given that, the biodeterioration of OSB panels must be investigated to improve its durability. In this way, this work analyses the biological resistance against termites (Cryptotermes brevis and Nasutitermes corniger) of heat-treated OSB panels made with Eucalyptus wood glued with vegetable-based polyurethane-an eco-friendly and sustainable adhesive derived from castor oil. Various panels were produced with different layers compositions (face:core:face of 25:50:25 and 30:40:30) in wood… More > Graphic Abstract
