Abstract:Traditional wood-based panels are usually made from large-diameter trees and rely on adhesives for compactness, which negatively impacts the environment and human health. However, the widely distributed small-diameter shrubs are good raw materials for wood-based panels with abundant fibers, but are often under-exploited. This research reports the preparation of self-bonding biocomposites from Buxus sinica by an innovative combined approach of extraction, alkali treatment, and hot molding. The resulted biocompo… Show more
“…However, this preference has imposed a significant burden on the environment. , Wood–plastic composite material is the most common furniture material on the market . Although it reduces the dependence on wood to a certain extent, it still requires the use of wood. − The implementation of waste PET composite boards in furniture production offers an innovative solution to addressing environmental concerns associated with traditional wooden furniture.…”
The inadequate recycling rate of waste polyester textiles (PET) is a significant issue that needs to be addressed. This paper proposes PET/polypropylene (PP) composite boards as a more effective approach to achieving the efficient recovery of waste PET textiles. The study investigates the mechanical, hydrophilic, and thermal conductivity properties to explore its potential as a furniture board. The addition of PET enhances the mechanical properties and insulation performance of the composite boards. The chemical structure, crystalline structure, and hydrophilicity of PP remain unchanged. Furthermore, the color on the surface of the boards is uniform. Compared with common furniture materials available on the market, these composite boards exhibit superior mechanical properties, making them suitable for use as furniture boards.

“…Wang et al 3 developed a high-strength rice husk-based composite after compacting rice husk through hot pressing and applying polyvinyl alcohol as a binder. Ren et al 4 proposed a novel approach for deriving selfadhesive biocomposites from boxwood through combination extraction, alkali treatment, and hot pressing. The resultant biocomposite exhibited a higher bending modulus (7.79 GPa) and tensile modulus (4.33 GPa).…”
With the increasing prominence of global environmental issues and the growing demand for sustainable development, biomass composites have attracted widespread attention as candidates for environmentally friendly and renewable construction materials. In this study, environmentally friendly biomass-ash composites (BACs) were fabricated using hydrothermally activated incinerated sewage sludge ash (HT-ISSA) as filler and straw powder with waste sawdust as the biomass matrix for hot pressing. An investigation was conducted into the effect of HT-ISSA on the physical properties of the composite, including the bending strength, compressive strength, and thermal conductivity. The composite prepared with 15 wt% HT-ISSA demonstrated an exceptionally high bending strength (30.60 MPa), compressive strength (44.76 MPa), and low thermal conductivity (0.2380 W/m·K). The enhanced physical properties of the BAC material are attributable to the change caused by hydrothermal treatment of the filler phase. Due to the introduction of hydrated calcium silicate, the cohesion performance of the filler significantly improved, thus leading to strong adhesion and penetration within the matrix. The obtained BAC is applicable for packaging and insulation materials, thus providing an effective solution for the economical and environmentally friendly recycling of incinerated sewage sludge ash and other bulk solid waste. Additionally, it contributes novel insights into alleviating the current shortage of forest resources.
