Decay and termite resistance of particleboard manufactured from wood, bamboo and rice husk

Abstract

The resistance of particleboards, made from wood, bamboo and rice husk, to fungi and termites was evaluated. Panels were composed of 100% wood (Eucalyptus grandis), 100% bamboo (Bambusa vulgaris), 100% rice husk (Oryza sativa), 50% wood and 50% bamboo; and 50% wood and 50% rice husk. Panels exposed to the decay the brown-rot fungus (Gloeophyllum trabeum and the white-rot fungus (Trametes versicolor), and, in a choice feeding trial, to termites (Nasutitermes corniger). The rice husk particleboards had the highest resistance of all samples and the bamboo particleboards had the lowest resistance. T. versicolor fungi produced a larger mass loss in the particleboards than did G. trabeum.

Some of the Physical and Mechanical Properties of Particleboard Made from Betung Bamboo (Dendrocalamus asper)

“…The white-rot fungus S. commune can degrade chemical components, especially lignin in D. asper bamboo [52,53]. Moreover, white-rot fungi in general cause most severe attacks, with different effects for all the main chemical constituents, especially cellulose, polyoses, and lignin [54].…”

Technological characterization of particleboards constituted with pistachio shell (Pistacia vera) and Pinus oocarpa wood

“…For production wood from reforestation are utilized as a raw material, however the panels can be manufactured with any material containing cellulose and lignin as long as they provide satisfactory properties as dimensional stability. The quality of the final product is directly related to the type of raw material that will be used (Melo et al, 2015). Using diversified materials, associated or not, with wood can contribute in a positive direction to meet the demand of the timber sector, in addition to diversifying the sources of raw materials and adding value to alternative materials or waste.…”

Lignocellulosic Composites from Acetylated Sunflower Stalks

“…Therefore, looking for potential replacements for slow-growing trees is of great importance, and available agricultural plants might be good alternatives [12,13]. A variety of plants have been studied for use in composites manufacturing, including vine stalks [14], topinambour stalks [12,15], cotton stalks [16,17], coconut chips [18], bamboo chips [19][20][21], flax chips [22], and banana chips [23]. Other agriculture residues also include rice and wheat straw [24,25], canola straws [26], reed stem [27], date palms [28], oil palms and poppy husks [29], and stalks from cotton [30].…”
