“…This is similar to the study reported by Suchart and Thaipetch ( 2004) with specific gravity of G. albociliata ranging from 0.62 to 0.68. Despite this, it has a lower specific gravity (0.74 to 0.90) than G. levis, which was studied by Osman et al (2022). Figure 1(b) shows that the number of vascular bundles increases and becomes tighter together from the bottom to the top.…”

Thirteen bamboo species are reported to be in commercial use in Malaysia. However, Buluh madu (Gigantochloa albociliata) did not make to the list. As a species, G. albociliata is cultivated for its delicious bamboo shoot and is demonstrated to possess great potential to produce commercialised products such as laminated bamboo panel. Unlike common bamboo, which has hollow cylindrical culms, G. albociliata has thick culms at the base, with smaller hollow cavities at the top portion. Therefore, it can be easily converted into high-thickness strips, thus improving the processing efficiency of laminated bamboo. To validate this theory, the anatomical, chemical, physical, and mechanical properties of G. albociliata were evaluated. The round bamboo and strips from the top and bottom sections of the bamboo stem were tested. It was found that G. albociliata has a vascular bundle type similar to that of the Gigantochloa genus bamboo. The fibre in G. albociliata is long and strong. The top section of bamboo has longer fibres, a higher density, and a higher specific gravity than the bottom section. As a result, bamboo from the top section has greater bending strength than bamboo from the bottom section. The G. albociliata species was discovered to have high mechanical strength, dimensional stability, and good wettability, making it an ideal material for laminated products.

“…If particular natural forests are reduced, it is a great substitute for wood due to the decreasing availability of lumber and growing concern among consumers of wood manufactured commodities about the environmental impacts. Bamboo's structural, physical, and inherent resilience are changed based on a number of variables such as farming practices and heredity [27]. Guada bamboo and Moso bamboo are the two most popular species used in construction; they have the equivalent strength-to-weight ratio as steel and about double the compression-to-weight ratio of concrete, indicating their high ability to endure tremendous pressure and weight [28].…”

The aim of this study is to investigate the impact of the construction industry on the environment in Malaysia and propose strategies for mitigating its adverse effects through the adoption of sustainable building techniques. The study recognizes the importance of a healthy ecosystem in promoting health conditions, improving living standards, and ensuring a sustainable future for the nation. However, the recent population expansion has placed increased pressure on Malaysia's building industry and infrastructure, resulting in environmental degradation caused by the construction sector. To address this issue, the study examines the overall framework of ecological management implemented in Malaysia's construction industry. It evaluates key aspects of construction management, including the formulation and implementation of environmental policies, the involvement of stakeholders in decision-making processes, and the effective management of construction waste. Additionally, the study conducts a comprehensive assessment of specific regulations and guidelines pertaining to construction waste, water contamination, and air pollution, all of which are prevalent issues in Malaysia's construction activities. Furthermore, the study highlights the benefits of using green materials in construction to minimize environmental impact and enhance overall quality of life. It explores the implementation of green technologies in Malaysia, considering their advantages and disadvantages within the local context. By doing so, the study aims to provide insights into the challenges faced in the widespread adoption of green technologies, taking into account the perspectives of the government, economy, society, and available resources. Ultimately, the study emphasizes the need for collaboration among all stakeholders to address environmental damage effectively. It stresses the importance of an inclusive approach, ensuring that no one is left behind in the efforts to rectify the situation and prevent further deterioration of the environment. By taking proactive measures and implementing sustainable building techniques, it is hoped that the construction industry in Malaysia can contribute to a greener and more sustainable future for the nation.

“…In recent years, bamboo has gained popularity as a substitute for wood due to its rapid growth, short rotation cycle, simple cultivation methods, excellent mechanical strength, moderate to high density, straightforward processing, and versatility in various industrial applications. Additionally, the global focus on bamboo has significantly risen due to the shortage of forest resources and increased global demand for wood raw materials [ 1 , 2 ]. A viable approach for enhanced valorization of bamboo is its use for manufacturing lignin-based composites, e.g., bamboo oriented strand boards (BOSBs) [ 3 , 4 , 5 ].…”

This study aimed to analyze the effect of pre-heat treatment on bamboo strand properties and its impact on the properties of the resulting bamboo-oriented strand board (BOSB). Giant bamboo (Dendrocalamus asper (Schult.) Backer) with a density of 0.53 g cm−3 was converted into bamboo strands. These strands were pre-heat-treated at 140 and 160 °C for a duration of 1, 2, and 3 h. Changes in the chemical composition of the strand due to subsequent treatment were assessed. Fourier-transform infrared spectroscopy (FTIR) and X-Ray diffraction analysis (XRD) were used to determine the changes in the chemical composition of bamboo strands. The BOSB panels were produced with a target density of 0.7 g cm−3. The manufacturing of the BOSB was conducted in three layers with a ratio of 25:50:25, bonded with phenol-formaldehyde resin. The physical and mechanical properties of the laboratory-fabricated BOSB were tested in compliance with the criteria given in JIS A 5908 standards. Comparisons were made against OSB CSA 0437.0 Grade O-1 commercial standard. The pre-heat treatment led to chemical alterations within the material when set at 140 and 160 °C for 1 to 3 hours (h). FTIR spectral analysis demonstrated that longer exposure and higher temperatures resulted in fewer functional groups within the bamboo strands. The increased temperature and duration of pre-heat treatment enhanced the crystallinity index (CI). The dimensional stability and mechanical properties of the composites were improved significantly as hemicellulose and extractive content were reduced. This study demonstrated that the pre-heat treatment of bamboo strands at a temperature of 160 °C for a duration of 1 h was an adequate approach for heat modification and fabrication of BOSB panels with acceptable properties according to OSB CSA 0437.0 Grade O-1 commercial standard.
