Characterization of Particleboard from Waste Tea Leaves (Camellia Sinensis L) and Meranti Wood (Shorea Sp) using Urea-Formaldehyde Adhesive and It’s Formaldehyde Emission

: The production of particleboard still uses formaldehyde-based adhesives, such as urea formaldehyde (UF) adhesives, although it has been known that the adhesive is harmful to human health in the long term. Therefore, an effort is needed to get adhesive that is relatively safe to use. One of them is by utilizing tea plant waste which can reduce formaldehyde emissions. The purpose of this study was to evaluate the physical and mechanical properties of particleboard, to evaluate the ratio of waste tea leaves (Camellia sinensis L)and meranti wood ( Shorea sp ) particles, and to evaluate the effect of adding waste tea leaves for formaldehyde emissions produced by particleboard. The results showed that the addition of tea leaf particles can improve the physical and mechanical properties of the particleboard.
