“…Lignin adhesives are often chosen as a natural and eco-friendly alternative, while UF adhesives are commonly selected for their water-resistant properties [61]. Manufacturers make the appropriate adhesive choice based on the intended application and the performance requirements of the final product [62].…”

Lignin extraction from bark can maximize the utilization of biomass waste, offer cost-effectiveness, and promote environmental friendliness when employed as an adhesive material in bark particleboard production. Particles of fine (0.2 to 1.0 mm), medium (1.0 to 2.5 mm), and coarse (2.5 to 12.0 mm) sizes, derived from the bark of Leucaena leucocephala, were hot-pressed using a heating plate at 175°C for 7 min to create single-layer particleboards measuring 320 mm × 320 mm × 10 mm, targeting a density of 700 kg/m 3 . Subsequently, the samples were trimmed and conditioned at 20°C and 65% relative humidity. In this study, we compared bark particleboard bonded with urea formaldehyde (UF) adhesive to fine-sized particleboard bonded with demethylated lignin adhesive. The results indicated that bark particleboards utilizing demethylated lignin and UF adhesives exhibited similar qualities. Coarse particleboard showed differences in modulus of elasticity (MOE) and modulus of rupture (MOR), while medium-sized particles exhibited significant variations in moisture content (MC) and water absorption (WA). Furthermore, the thickness swelling of coarse and medium-sized particles under wet and oven-dried conditions exhibited notable distinctions. Overall, the demethylated lignin adhesive extracted from L. leucocephala bark demonstrated similar quality to UF adhesive, with particle size correlating inversely to the strength of the bark particleboard.

“…In addition to soy protein, some other proteins can also be cross-linked with isocyanates to prepare wood adhesives with good properties. Liu et al 16 employed ethanol and isophorone diisocyanate (IPDI) as the primary chemical additives in order to create an innovative and eco-friendly approach for producing wood adhesives based on wheat gluten (WG) that exhibit excellent performance. WG was dissolved in ethanol, and then modified with IPDI cross-linking agent.…”

“…In addition, UF resin adhesive, melamine resin adhesive and PF resin adhesive are also known as “trialdehyde adhesive” because they all use formaldehyde as raw material. 16 The conventional production process for “trialdehyde adhesive” involves the release of formaldehyde gas, precipitating both environmental contamination and health hazards. Substituting biomass for the requisite formaldehyde in the production process, 17 or blending biomass with formaldehyde adhesives, 18 offers an avenue for diminishing formaldehyde emissions during application.…”

“…This led to changes in the spatial structure of proteins and physicochemical properties that affect their applications ( He et al, 2019 ). Physical modifications to change the spatial structure and intermolecular aggregation of proteins was carried out by modest thermal denaturation, mechanical treatment, and ultrasounds ( Liu et al, 2021 ). However, physical modifications have high equipment demand, which is difficult to apply in large scale for industrial applications.…”
