A Review of Particleboard Development and Performance Using Non-Toxic and Biodegradable Adhesives

Abstract

<p>The demand for wood-based materials in particleboard production is increasing, but so are the costs and concerns about the environment and health. As a result, researchers have been exploring alternative raw materials. This review critically examines the development of particleboards using novel adhesives derived from food waste and agricultural by-products, comparing them to the commonly used Urea-Formaldehyde (UF) resins. The study focuses on the environmental and health risks associated with UF resins, including their potential to cause cancer and respiratory problems. In search of sustainable and safer alternatives, the research investigates bio-based adhesives as potential solutions for the sustainability challenges in particleboard manufacturing. The study includes a thorough analysis of the chemical composition and properties of ureaformaldehyde resin, recognizing its strong tensile strength and bonding capabilities but also highlighting the environmental and health risks it poses. In contrast, the study explores a range of alternative binders, such as soy protein, lignin, tannin, and starch based adhesives. These bio-based adhesives, derived from renewable sources, are examined for their eco-friendliness and potential to mitigate the negative impacts of conventional adhesives in particleboard production. The findings of the study reveal that particleboards made with alternative adhesives not only match but sometimes even surpass the physical and mechanical properties of those made with UF resin. Importantly, these alternative adhesives are non-toxic, making them suitable for construction applications and reducing the health risks associated with the high levels of formaldehyde emissions from UF resin based particleboards. This research confirms the feasibility of using sustainable materials in particleboard production and aligns with global efforts for environmental conservation and public health protection. By addressing research gaps, this study contributes significantly to the advancement of sustainable and health-conscious practices in the particleboard industry.</p>
