“…Fine particles had a higher specific surface area (Table 3), which improved the accessibility to inner cell wall components [58]. The use of fine particles led to a larger area of contact and reactivity between particles, resulting in an internal chemical reorganization during thermocompression and better selfadhesion of the material with more interparticle bonding [59,60]. Regarding the effects of the hemicellulose content on the materials (15-22%), a lower hemicellulose content seemed to lead also to a material with better mechanical properties.…”

The aim of this study was to assess the influence of thermocompression conditions on lignocellulosic biomass such as sugarcane bagasse (SCB) in the production of 100% binderless bio-based materials. Five parameters were investigated: pressure applied (7-102 MPa), molding temperature (60-240°C), molding time (5-30 min), fiber/fine particle ratio (0/100-100/0) and moisture content (0-20%). These parameters affected the properties and chemical composition of the materials. The density ranged from 1198 to 1507 kg/m3, the flexural modulus from 0.9 to 6.9 GPa and the flexural strength at breaking point from 6.1 to 43.6 MPa. Water absorption (WA) and thickness swelling (TS) respectively ranged from 21% to 240% and from 9% to 208%. Higher mechanical properties were obtained using SCB with fine particles, low moisture content (4-10%), high temperature (≥ 200°C) and pressure (≥ 68 MPa), while water resistance was improved using more severe thermocompression conditions with the highest temperature (240°C) and time (30 min) or a higher moisture content (≥ 12.5%). Correlations were noted between the mechanical properties and density, while the material obtained with only fine particles had the highest mechanical properties and density. Material obtained with a 30 min molding time had the lowest WA and TS due to internal chemical reorganization followed by hemicellulose hydrolysis into water-soluble extractables.

The production of particleboards without the use of synthetic binders is desirable to prevent environmental problems. This study has produced experimental binderless boards from untreated sawdust from Abura wood using a laboratory press. Response Surface Methodology using Box-Behnken experimental design was utilized to investigate the influenceof pressing variables (pressure, pressing temperature and pressing time). Density of the bioboards produced wasbetween 523.69 and 738 kg/m3which was comparable tomedium density fibreboards. The maximum values for Internal Bonding Strength (IB), Modulus of Rupture (MOR)andModulus of Elasticity (MOE) were 0.049 MPa,1.1 MPaand100.4 MPa, respectively. It was shown that, for the range of factors studied, pressure and the pressing temperature were the more significant factors in determining the density, MOE and IB. This study showed that the sawdust can potentially be used for the manufactureof binderless boards.
