This study was carried out to investigate the suitability of particleboards using uprooted tea plants (Camellia sinensis). Wastage and uprooted tea plants were collected from Neptune Tea Garden, Chattogram. The uprooted tea plants were cut into the clipper machine into small portions. Following that, they were processed into chips using a hammer mill machine, which was then dried in a batch oven to the suitable moisture content (5%). Single-layer particleboards were fabricated in a laboratory hot press machine with four different densities i.e. 650, 700, 750 and 800 kg/m3 using liquid urea formaldehyde as an adhesive. Finally the physical and mechanical properties of particleboards made from uprooted tea plants were studied. Characteristics of particleboards such as modulus of rupture (MOR), internal bond strength (IB), water absorption (WA) and thickness swelling (TS) were measured as a part of the experiment. Results show that particleboards made from uprooted tea plants of 800 kg/m3 density had good static bending MOR property (112.00 kg/cm2) and excellent IB strength pioperty (10.04 kg/cm2). The mean MOR value of the 800 kg/m3 density particleboards was above the Indian (IS 3087, 2005) and ANSI (A208.1-1999) standaid specifications but lower than the British (BS 5669-2:1989) standard specification. Moreover IB strength value was above the Indian, ANSI and British standaid specifications.
