“…Specifically, the average weight loss rates for the untreated and heat-treated samples were 5.31 and 2.04%, respectively, while the termite mortality rates were 38.70 and 66.70%. In a similar evaluation, Manalo and Garcia treated Dendrocalamus asper with oil-based heat at temperatures of 140, 160, 180, and 200 • C [43]. Samples treated for 30 min exhibited increased termite resistance at higher temperatures; however, samples treated for 120 min showed no significant changes in termite resistance, except for the sample treated at 200 • C. Moreover, all treated samples demonstrated lower weight loss rates than the untreated samples.…”

This study aimed to assess the effectiveness of large-scale heat treatment on Moso bamboo (Phyllostachys pubescens) grown in South Korea. The process involved multiple stages, including pretreatment, boiling, steaming, heating, and cooling. Heat treatment successfully reduced the water content to below 3% and increased the specific gravity from 0.62 to 1.12, thereby enhancing dimensional stability and strength. Following an ultraviolet-accelerated weathering test, the heated Moso bamboo exhibited improved color stability (ΔE 5.84) compared to untreated bamboo (ΔE 9.92). Furthermore, the heat-treated bamboo demonstrated high resistance against wood-rot fungi (weight loss < 10%) and termites (weight loss approximately 2%). In contrast to small lab-scale drying processes, this study employed a pilot-scale kiln for mass production, resulting in large-sized Moso bamboo with enhanced properties. This study revealed that distinct results, including extractives and lignin-degraded compounds, persisted in heated Moso bamboo cells after the heat treatment. The overall improvement in deterioration resistance, achieved through heat treatment, significantly contributes to the durability and longevity of bamboo materials in outdoor settings, such as landscape facilities.

“…In addition, the surface layers had higher density and hardness than the material inside of the samples (Rautkari et al 2013), which may have conferred resistance to the hot pressed surfaces treated at 220 °C. Manalo and Garcia (2012) examined bamboo's resistance to termites after treating in hot oil at 200 °C, and the treatment duration had no significant effect on damage rating. Spruce and beech wood samples had improved resistance against termites after heat treatments at 220 °C over longer periods of time, but the mechanical properties were degraded (Duarte et al 2012).…”

Oil palm trunks are a by-product of oil palm plantations and provide raw material to the woodworking industries. However, their resistance against degradation by termites needs to be improved; this study investigated hot pressing as a chemical-free method to improve resistance. The main objective was to assess resistance to termites conferred to oil palm wood by hot pressing at various temperatures (140, 180, and 220 °C) for a fixed duration of 8 min and maximum pressure of 2 MPa. The samples were the only available nutrition to subterranean termites (Coptotermes gestroi Wasmann) in a 4-week no-choice test. The thermally compressed oil palm wood did not show any significant effect of the pressing temperature on mass loss, but the surface damage to the samples with treatment at 220 °C indicated improved resistance to subterranean termites based on visual observation.

“…However, there is still a lack of information on different properties of particleboard panels manufactured from bamboo particularly their biological resistance including termites and decay as well as the surface quality. Previous studies carried out on D. asper culm assessed the resistance to subterranean termites [18,19], while Suprapti [20] investigated the resistance to fungal attack. The majority of particleboard is used as a substrate for thin overlays.…”

The objective of this study was to evaluate various physical and mechanical properties of experimental particleboard panels made from Asian giant bamboo (Dendrocalamus asper). Single layer panels having a density level of 0.75 g/cm3 from coarse and fine particles were used within the scope of this study. Thickness swelling, water absorption, surface roughness, and wettability characteristics of the samples were tested as physical properties while bending, internal bond strength, and screw withdrawal strength of the panels were considered for their mechanical properties. Resistance of the panels against termite and fungus were also determined. Based on the findings in the work both physical and mechanical properties of the panels made from coarse particles resulted in higher values than those made from fine particles with the exception of their internal bond strength. It appears that using fine particles in the panels enhanced their overall surface quality as well as wettability. Regarding biological deterioration of the samples, those made with coarse particles had better resistance. It seems that giant bamboo as a non-wood lignocellulosic species would have potential to be used as raw material to the manufacture value added particleboard with accepted characteristics.
