“…Over the past two decades, with increasing deforestation for wood around the world, most research and researchers are frequently trying to come up with new ideas to develop a wood-based alternative to achieve the demand on this natural resource and save the future happiness of the nature earth. In terms of innovation and quality of materials, technology has formed new products derivative from wood, either in different forms or in combination with other materials, or by making wood-plastic composites (WPC) made up of wood waste and plastic material in the exploration of environmental welfares, and with better product performance [1][2][3]. Wood sawdust is substance significantly used in reinforcing polymer from both a technical and a marketable point of view [4,5].…”

Sawdust is a natural composite obtained from natural resources such as shrubs and trees and in a large amount from the wood industry as a waste. This study aimed to evaluate the mechanical and water absorption properties of alkaline-treated wood sawdust-reinforced polypropylene composite. The composites were manufactured by the melt-mixing method followed by compression molding with amounts of wood sawdust ranging from 10, 20, 30, and 40 to 50 wt. % by volume. The produced composites were characterized for their mechanical and water absorption characteristics. The results indicated that increasing the amount of wood sawdust content up to 40% improves the tensile, flexural, impact, and compressive strength of the composites but after the wood sawdust contents reach 40%, the mechanical properties of the composite were decreased. Water absorption rate has increased with an increase in the wood sawdust proportion; this is due to the presence of –OH groups on the surface of wood particles. From the result of this study, it can be also concluded that the optimal mechanical and water absorption properties were attained at 40% wood sawdust content. Therefore, sawdust can be used as filler and reinforcement in the PP matrix, which will reduce cost and give environmental benefits.

“…In addition, the manufacture of particleboard without a hot press also affects the thickness of the particleboard. Heat treatment can increase the dimensional stability of the board by reducing the thickness of the particleboard [27]. The dimensional stability of the particleboard is seen with a decrease in the value of the resulting thickness expansion [28].…”

Bamboo can be used as a material in the manufacture of particleboard. The purpose of this study was to examine the effect of various types of bamboo and their adhesion on the physical and mechanical properties of particleboard. The study used a factorial completely randomized design with three repetitions. Particleboard made using cold pressing made of bamboo betung (Dendrocalamus asper Schult.), bamboo apus (Gigantochloa apus Kurz), bamboo ori (Bambusa arundinacea Retz), and Urea Formaldehyde and Polyvinyl Acetate adhesives. The particle size used was through eight meshes with an adhesive concentration of 20% and a target board density of 1 gram/cm³. Board testing using SNI 03-2105-2006, correlation analysis, and regression to see the relationship between variables. The resulting particleboard has a density between 0.5 – 0.69 gram/cm³, air content between 12.7% - 15.2%, thickness expansion between 2.2% - 17.55%, MOE 1.963 - 4.898 kg/ cm², MOR 4.89 – 9.36 kg/cm². The type of bamboo has no significant effect on density, moisture content, MOE, and MOR of particleboard. The type of adhesive has a significant effect on the density, MOE, and MOR of the particleboard. The interaction between the type of bamboo and the type of adhesive has a significant effect on the thickness development of the particleboard.

“…Wood-based boards are more isotropic composite materials than solid wood, produced by bonding different shaped pieces of wood under pressure and at high temperatures (Mesquita et al, 2019). These high temperatures used in the production of wood-based composite boards cause a decrease in the hygroscopicity of the materials (López et al, 2018). Improving the dimensional stability of woodbased panels such as particleboard and the development of water-resistant wood composites have long been the target of wood technology experts and the industry (Mesquita et al, 2019).…”

The aim of the study is to investigate the production possibilities of particleboard by using waste tirerubbers with different properties as fillers and find a solution to a serious environmental pollution problem caused by waste tires. For this purpose, waste summer and winter tires were ground, rubber powders were obtained by separating rubber materials from other materials, and particleboards with different properties were produced using this sawdust in different percentages. The oven-dry density, air-dry density, and equilibrium moisture content at (65±5) % RH and (20±2) ºC, thickness swelling (TS, 2 hours and 24 hours), water absorption (WA, 2 hours and 24 hours) characteristics, bending strength, modulus of elasticity, and internal bond strength were determined according to the applicable European standards. The hydrophobic nature of the tire rubber enhanced the water absorption ratios of particleboards. In addition, mechanical performance of groups was affected by tire content, and it was mainly determined that the values decreased dramatically with increasing tire content. It was especially observed that this decrease was more pronounced when subtracting 30 % to 20 % waste tire content. The groups including winter waste tire rubber achieved better performance than summer waste tire groups. The use of waste rubber in boards resulted in a decrease in the equilibrium moisture content and mechanical strength of the samples.
