“…Meanwhile, other researchers had crosslinked starch with polyvinyl alcohol which later increases their shear force resistance of the adhesive from 1000 kg of using native starch to 2700 kg [13]. e most recently used modified starches for manufacture of wood composites were epichlorohydrinmodified starch [21,22], glutardialdehyde-modified starch [23,24], and carboxymethyl-modified starch [25]. e source of starch, the oil palm tree, initially originated from West Africa [26].…”

Oil palm trunk is a kind of biomass rich in starch content. Oil palm trunk waste was available throughout the year in Malaysia and Indonesia due to continuous felling of nonproductive, over 25-year-old trees. Even though some manufacturers were using it in plywood and veneer production, they are hard to handle which later becomes less favorable raw materials due to a high moisture content where combination with a high starch content quickly attracts fungus and wood-decaying agents. The objective of this work was to evaluate properties of experimental wood composite panels, manufactured using oil palm-extracted starch modified with glutardialdehyde (OPSMG) as a binder. Different analyses were employed to characterize the properties of the samples besides evaluation of bending, internal bonding strength, and dimensional stability of the panels. Characterization on the functional group using the FT-IR analysis showed presence of aldehyde groups and ketone stretching vibrations at 1736.05 cm−1 and 1596.25 cm−1, which proves the presence of glutardialdehyde besides formation of bonding between the OPSMG and the woody materials. The XRD analysis showed the starch modification had lowered the crystallinity index which in turn increased the strength of the manufactured wood composites. The OPSMG wood composites were also found to have lower thermal stability, as evaluated using the TGA analysis. It was recorded that the maximum modulus of rupture for OPSMG wood composites was achieved at the 0.80 g/cm3 density level with an average value of 15.446 N/mm2 which showed 38.00% increment in strength between those two types of wood composites. Thickness swelling after immersion in water can still be improved by incorporating the moisture-repellent material later. After analyzing the results, it was concluded that modified oil palm starch has the potential to be used as an environment friendly binder for wood composite making.

“…The bonding strength and stability of emulsion were significantly improved by addition of hydrophobic butyl acrylate into the adhesive formulation. The adhesive also exhibited good stability at room temperature and low level of around 81.2 g L −1 total volatile organic compounds emission …”

Due to extensive utilization of fossil fuels, the energy demand of the growing population of the world is increasing day by day. The utilization of these fossil fuels also results in environmental pollution and energy crisis around the globe. As such, scientists and academics are trying to develop green materials which tend to reduce the impact of human on environment. Starch is the most abundant organic compound found in nature after cellulose. Thus, starch is an attractive natural green material candidate for researchers to replace the petro‐chemical‐based ingredients in wood composite products. There is an increasing demand for the wood adhesives in the recent years due to increasing applications of wood products. The wood adhesive industry remains dependent on the petroleum resources due to attributes such as high performance and low cost. However, these adhesives can create serious risks to human health and spoil the indoor air quality by emitting these carcinogenic compounds into the environment. Therefore, there is a growing interest to replace the petro‐chemical based ingredients in the adhesive formulation with green renewable material. This review focuses on research conducted in the recent past to develop adhesive for wood application from green renewable material such as starch.

“…Alternatively, studies have been conducted on using starch as a green adhesive for wood composites. As examples, epichlorohydrin modified oil palm starch, 8 citric acid modified pea starch, 9 epichlorohydrin modified rice starch, 10 corn starch-tannin combination 11 and glutardialdehyde modified corn starch 12 are among the binders that have been extensively used to formulate wood composites. Despite its ability as a green binder, starch is also consumed as a staple food and is widely used as a food ingredient.…”
