“…In addition, other protein-based materials have been studied and reported to produce good wood bonding. Among these proteins are wheat gluten (Trischler et al 2018;Xi et al 2021), pea protein (Santoni and Pizzo 2013), peanut meal (Li et al 2015), and blood meal protein (Li et al 2018).…”

Defatted cottonseed (CS) and water-washed CS meals were prepared from glandless CS and were used in adhesive formulations to produce three-ply yellow poplar plywood panels. Adhesive resins were prepared from each protein meal with sodium bisulfite and one of two polyamido-amine-epichlorohydrin (PAE) wet strength agents, and the plywood panels were produced by hot pressing. Shear strength and water resistance were determined by American Society for Testing and Materials (ASTM) and American National Standards Institute for Hardwood and Decorative Plywood/Hardwood Plywood and Veneer Association (ANSI/HPVA) methods and were compared with the properties of plywood panels made with an adhesive formulated from a commercial soybean meal. Panels prepared from three protein meals had comparable shear strengths. The combinations of the two CS preparations and the two wet strength agents produced panels with acceptable wet resistant properties, whereas the soybean meal only produced acceptable panels with one of the wet strength agents. Because the panels prepared from the two CS meals had comparable properties, there appears to be no benefit to including a water-washing step to increase the meal's protein level. In contrast with a recent literature report suggesting the addition of alkali to elevate the formulation pH was necessary with CS meal, suitable panels were prepared herein without the addition of the base. This difference may have been due to the slightly higher pressing temperature and longer press times used in this work compared with earlier results. The CS meals showed promise as formaldehyde-free hardwood-plywood wood-based adhesives for interior applications.

“…Several industrial proteins are available for the development of technical applications and present a lot of advantages such as safety, and low-cost [1]. Recent research shows that wheat gluten adhesives are used in wood applications [2,3,4], foam used in fighting fires [5], coating [6][7]. Casein has an excellent biocompatibility, biodegradability, and high abundance [8].…”

“…Wheat flour is widely used as an extender for synthetic resins in wood products [23] and its main component (starch) is known for its good adhesive performance, as it is able to interact with wood surfaces after gelatinization of starch granules [8]. Proteins (gluten) in wheat flour (WF) also present adhesive properties because glutenin and gliadin crosslink when subjected to heat [24], and its wood adhesion properties have been widely studied [25,26,27,28,29].…”

Currently, the majority of binders used in wood particleboard (PB) manufacturing are formaldehyde-based synthetic resins. Because of the toxicity of formaldehyde, there is a strong demand for eco-friendly alternatives with similar performances and economic viability. In this work, thick spent sulfite liquor (TSSL), an industrial byproduct from sulfite pulp mills, is proposed as a binder for fully bio-based PBs. The results showed that PBs bound with TSSL present appropriate mechanical performance, which was further improved when TSSL was combined with wheat flour at an 84:16 dry weight ratio and preheated to 94 °C prior to application. For 13.2% binder content per dry wood weight, the PB internal bond strength was 0.46 N mm−2, which is above the standard requirements for PB type P2 (0.35 N mm−2). Optical microscopy showed that TSSL hinders the gelatinization of starch granules during preheating, allowing the binder mixture to maintain a low viscosity suitable for combination with wood particles and PB production.
