“…The ash content of G. atroviolacea bamboo is 3.29% which higher than the current results of aged from 1-3 years-old of Giant Timber bamboo (1.87-2.71)%. However, Giant Timber bamboo aged from 1-3 years old is similar the ash content of G. apus and G. levis are 2.45 and 2.46% respectively, which similar with the current results of aged from 1-3 years old of Giant Timber bamboo (1.87-2.71)% (Purbasari et al, 2016).…”

This research aims to examine the properties of culm based on the factors of age and height for structural and industrial purposes. Aged from 1-3 years old of culm and the height was divided into 3 parts which bottom, middle and top. The properties of Giant Timber bamboo in Ethiopia were not investigated so far from the other research work using age and height factors. 3 Samples of the culm are harvested at each age in the Amhara region at Injibara town, Ethiopia and 6 specimens are prepared for each experimental work. New growth of the bamboo shoot has higher internodes length, internodes diameter, and culm thickness than the previous generates of bamboo shoot. Morphological characteristics of the culm are improved when the ages of culm younger. Moisture contents and shrinkage of culm decrease when the age of culm older, and along culm height goes from the bottom to top. However, oven-dry density, cellulose, and lignin contents increase when the age of culm older and along culm height goes from the bottom to top. Whereas hemicelluloses, extractive and ash contents decrease when the age of culm older and along culm height goes from the bottom to top. Higher moisture contents of culm used to easy extraction of fibers without damage, but it has higher shrinkage in the culm. Whereas higher basic density of culm used for structural and furniture making. Celluloses are used for the biofuel and pulp industry. The lignin used as a binder and improve the structural application of the culm. Whereas hemicelluloses are used in the paper industry.

“…However, bamboo ash normally has a high K content, , similar to the straw biomass such as wheat straw and corn stalk. The previous experience from straw biomass combustion − suggests that K can react with Si-containing compounds to form low melting temperature K-containing silicates and thus gives rise to the operation problem associated with the ash sintering and slagging.…”

In this work, the bamboo ash fusion and sintering characteristics were studied to evaluate its potential application in combustion for the production of heat and power. Poplar and wheat straw were used in the experimental test as the reference fuels for comparison. Standard ash fusion tests and ash sintering tests were carried out at elevated temperatures. The results indicate that bamboo has a low ash melting temperature of 862 °C, much lower than that of poplar. In spite of the high K content in bamboo ash, no severe melting and sintering was observed under the temperature lower than 1000 °C. The ashes after the tests were analyzed using SEM/EDX, XRF, and XRD techniques to illustrate the ash transformation behavior. Standard ash fusion tests indicated that the melting temperatures of bamboo, wheat straw, and poplar ashes are 862 °C, 770 °C, and 1088 °C, respectively. No severe sintering can be observed for poplar due to the large existence of refractory compounds. Ash sintering occurred when the temperature is higher than 800 °C, for wheat straw, due to the formation of the low melting temperature K-rich silicate. Additionally, bamboo ash has a relatively high P content compared to that of wheat straw, which facilitates the formation of high melting temperature compounds of K–Ca/Mg phosphates. Moreover, the ash content in bamboo is low. As a conclusion, bamboo is a good quality biofuel which can be fired in biomass combustion plants without severe sintering at a temperature lower than 1000 °C.

“…Yusoff et al [ 43 ] reported that the ash content of Gigantochloa albociliata ranged from 1.5–1.8%. Meanwhile, that of bangkele bamboo is equivalent to Gigantochloa apus (2.45%) and Gigantochloa levis (2.45%) but lower compared to that of Gigantochloa atroviolacea (3.29%) [ 50 ]. However, it is relatively higher than Gigantochloa brang , Gigantochloa levis , Gigantochloa scortechinii, and Gigantochloa albociliata.…”

This study aimed to analyze the basic properties (chemical composition and physical and mechanical properties) of belangke bamboo (Gigantochloa pruriens) and its potential as a particleboard reinforcement material, aimed at increasing the mechanical properties of the boards. The chemical composition was determined by Fourier transform near infrared (NIR) analysis and X-ray diffraction (XRD) analysis. The physical and mechanical properties of bamboo were evaluated following the Japanese standard JIS A 5908 (2003) and the ISO 22157:2004 standard, respectively. The results showed that this bamboo had average lignin, holocellulose, and alpha-cellulose content of 29.78%, 65.13%, and 41.48%, respectively, with a degree of crystallinity of 33.54%. The physical properties of bamboo, including specific gravity, inner and outer diameter shrinkage, and linear shrinkage, were 0.59%, 2.18%, 2.26%, and 0.18%, respectively. Meanwhile, bamboo’s mechanical properties, including compressive strength, shear strength, and tensile strength, were 42.19 MPa, 7.63 MPa, and 163.8 MPa, respectively. Markedly, the addition of belangke bamboo strands as a reinforcing material (surface coating) in particleboards significantly improved the mechanical properties of the boards, increasing the modulus of elasticity (MOE) and bending strength (MOR) values of the fabricated composites by 16 and 3 times.
