The possible use of surian tree (Toona sinensis Roem) branches as an alternative raw material in the production of composite boards

Abstract

The current research focuses on the utilization of branches and twigs of surian as raw material for making composite boards in an effort to utilize the waste part of surian stem wood waste. The types of particle board and oriented strand board were bonded with phenol formaldehyde (PF) of 10% resin content. Variations of board density and board types were focused in this research. The boards were evaluated based on Japanese Industrial Standard (JIS). The results showed that the density of the board affected the physical and mechanical properties of the composite board. Strand boards were better than particle boards with regard to mechanical properties. Physical properties that met the testing standards were moisture content, density, water absorption and thickness swell for both after soaking 2 h in water, while for the mechanical properties test, only modulus of elasticity (MOE) met the standards. However, for further study, it seemed that generally this initial study informed that it was possible to make composite boards from the raw materials, both branches and twigs, with the additional treatment such as changing the size of particles and strands that could improve the properties of the board.

Upcycling Different Particle Sizes and Contents of Pine Branches into Particleboard

“…In addition, all variants meet the requirements of the standard, and statistical analyses for the alternative raw material used show no statistically significant differences between the average IB values of 5 and 10% and 25 and 50%, as well as for 100 and 100 cl. Alamsyah et al [ 33 ] in their study indicate that IB results can be influenced by the mixing of particles with glue, sheet molding, and pressing and that the higher bulk density of the alternative raw material translates into higher IB results. In another study, the researchers used mulberry branches for particleboard, and the IB study obtained the following results sequentially for variants depending on particles size: 0.25–1 mm—1.43 N mm −2 , 1–2 mm—1.54 N mm −2 , and 2–4 mm—2.30 N mm −2 , at a particleboard density of 800–830 kg m −3 [ 34 ].…”

Possibility of Acacia Mangium Tree Branches as Particleboard Material

“…Adhesive content has a very significant effect on the level of water absorption. It is an important variable as it affects the thickness of the particleboard [12].…”

“…Particleboard made from the branches of jabon wood had better quality than other parts [11]. Another study on particleboard made from Surian tree branches yielded good physical and mechanical properties [12].…”

Differences and Correlations of Morphological Characteristics and Fatty Acid Profiles of Seeds of Toona sinensis

“…[2] The highly durable timbers of T. sinensis are valuable raw materials for furniture manufacturing. [3,4] In addition, the bark and roots of T. sinensis are used in traditional medicines for the treatments of dysentery, enteritis, flatulence and itchiness. [1,5] In recent years, increasing numbers of studies report that T. sinensis is rich in bioactive compounds, such as phenolics, [6] polysaccharides, [7] and triterpenoids, [8] and exhibits various beneficial functions for human health, such as antioxidant, anticancer, anti-angiogenesis, anti-inflammatory, anti-fatigue and anti-nociceptive effects.…”
