“…The results showed that panels made with freeze-dried cell produced lower values for WA and TS than the panels made with pure PHA. This result disagrees with the previous study of Baskaran et al (2012) in which the TS and WA of the panels made from palm trunk with the addition of freeze-dried cell were much higher than those made with pure PHA. However, none of the panels passed the requirement of the Japanese Industrial Standards which was in agreement with the findings of Baskaran et al (2012).…”

“…PHAs are attractive materials for various applications in many industries such as medicine, agriculture and tissue engineering, the production of nano composites and polymer blends and processes such as chiral synthesis (Philip et al 2007). Recently, Baskaran et al (2012) studied the application of PHAs as an adhesive in the particleboard production process. The results showed that the properties of particleboard made from oil palm trunks with the addition of only PHAs were superior to those of particleboard without the addition of PHAs.…”

The aim of this study was to investigate the effect of microwave pretreatment on the properties of particleboard made from para rubber wood sawdust with the addition of polyhydroxyalkanoates (PHAs). Para wood sawdust was pretreated with microwaves at different wattages (400, 600 and 800 W) Kata kunci: Habuk gergaji kayu getah para; ketuhar gelombang mikro; papan partikel; PHA; polihidroksialkanoat sawdust or rubber wood dust which is a major by-product of cutting, grinding, drilling or otherwise pulverizing wood with a saw or other mechanical device can also be considered as a new source of raw materials that can replace rubber wood in manufacturing panels. Moreover, the utilization of sawdust could help to reduce the amount of wood from forest which is wasted, by using the wasted products as a raw material in the production of valuable products such as particleboard. Particleboard is widely used for making furniture, interior decoration and appliances.

“…Later on, Shen (1986) proposed and patented a process for the production of binderless fiberboards, which made its industrialization possible. Different raw materials, such as coconuts (Van Dam et al 2004), oil palm (Baskaran et al 2012) and bamboo (Shao et al 2009), have been studied to determine their feasibility in the production of binderless fiberboards. Chemical and enzymatic pretreatments of raw materials provided new avenues toward the improvement of properties of binderless fiberboards, owing to their ability to form free radicals on the surface of fibers (Felby et al 1997a, b;Kharazipour et al 1997;RiquelmeValdes et al 2008;Widsten 2002;Hüttermann et al 2001;Müller et al 2009;Mai et al 2004;Kües et al 2007).…”

Binderless boards were produced from bamboo particles through a molding pressing process. The boards were investigated for the chemical and structural changes of lignin and their mechanical strengths to evaluate the mechanism of self-bonding. The structural transformations of milled wood lignin (MWL) obtained from raw bamboo and molding pressed bamboo boards were investigated by Fourier transform infrared (FT-IR), gel permeation chromatography (GPC), quantitative 13 C-NMR spectra, two-dimensional heteronuclear single quantum coherence (2D-HSQC) spectra, 31 P-NMR, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC) techniques. Both molding press temperature and time affected the distribution and abundance of typical lignin linkages (β-O-4′, β-β′, and β-5′), as well as the S/G ratios of the lignin, demethoxylation, and the contents of attached molecules (PCE). In addition, a decrease in aliphatic OH and an increase in phenolic hydroxyl groups occurred in lignin as molding pressing proceeded. The optimal internal bonding strength (0.98 MPa) of the bamboo binderless board was obtained under the condition of 180 ºC for 20 min. Although the lignin obtained under this condition was structurally similar to the raw MWL, the decreased molecular weight, increased phenolic hydroxyl groups, and observable glass-transition temperature (thermal softening of lignin) provide some evidence to explain the acceptable internal bonding strength.
