About Paper:

Considering the pressing issues of resource depletion and greenhouse gas emissions, replacing synthetic adhesives in engineered wood products with sustainable alternatives is becoming increasingly critical. Traditional adhesives like urea-formaldehyde (UF) are effective but contribute to environmental pollution through the constant release of volatile organic compounds (VOCs). Bio-based adhesives, such as those derived from soy flour (SF), mycelium hyphae and bacterial cellulose (BC), offer a greener solution but often struggle with inadequate bond strength, poor moisture resistance, and limited durability. This study focuses on improving the shear strength of mycelium and BC adhesives in 2-ply plywood by optimizing processing pressure. Yellow poplar is selected as the substrate due to its uniform wood structure, which resembles many softwoods used in plywood production, ensuring consistent and reliable results. By varying the processing pressure during adhesive application, the research measures the bond strength, moisture resistance, and durability of these bio-based adhesives. Success in this area could revolutionize the woodworking industry by providing a viable, eco-friendly alternative to synthetic adhesives and reducing reliance on non-renewable resources. Moreover, the insights gained from this study may have broader applications, potentially influencing other sectors reliant on adhesive technologies, such as automotive, packaging, and construction industries, thus contributing to the advancement of sustainable materials science and the promotion of green technologies.
