“…The average lengths of soft and hard wood fibre are 3.3 and 1.0 mm, diameters 33 and 20 µm, and strength 100170 and 90180 MPa, respectively [215]. The main applications of WPCs are initially used for construction applications (decking, docks, landscaping timbers, fencing) and non-structural applications, but now they have been widely used for a broader range of applications, including automotive, gardening and outdoor products [216]. According to the study by Markarian et al [217], the WPCs market, including thermoplastics and thermosets, has been estimated globally at 900,000 t, in which, 70% of this volume was consumed by North America, 20% in Europe, and 10% from Asia.…”

“…The water absorption capacity for all samples increased quickly during their initial swelling, then increased slowly, and finally reached equilibrium. Typical Fickian diffusion behaviors were observed for all samples (Alamri et al 2013). The NCI and NCII samples had WA values of 39.39% and 38.42%, while the NCIII and NCIV samples had lower WA values of 32.31% and 24.78%, respectively, after 30 h of immersion in distilled water.…”

Degradable Nursery Containers Made of Rice Husk and Cornstarch Composites

The degradation behavior was investigated for eco-composite nursery containers (NCs) prepared with rice husk and cornstarch adhesive modified with urea formaldehyde (UF) as a wet strength agent. The wet shear strength, water absorption capacities, and biological degradation of NCs within soil were also investigated. Quantitative analysis of the thermal degradation behavior of different NC versions was performed by thermo-gravimetric analysis (TGA). The results demonstrated that the introduction of the UF agent accelerated the soil degradation of the NCs matrix to a certain extent. The maximum cumulative mass loss was 51.1% when the UF content of NCs was 8 wt.%. Moreover, the dry strength of the mixed urea formaldehyde-cornstarch adhesive (UCA) was increased by 108.9% compared with cornstarch adhesive (CA). The results of this work indicate the improved biodegradability of the NC ecocomposites, which could make them potential sustainable alternatives for conventional plastic pots.

“…Natural fiber-reinforced PLA composites are gaining widespread interests and are continually growing in the market due to abundant availability, biodegradability, low density, and cost effectiveness ( Ref 1,2). However, the deterioration of PLA composite property is mainly attributed to exposure of moisture, radiation, chemicals, and microorganism.…”

This work reports on the influence of moisture absorption and accelerated weathering on the properties of graft copolymer compatibilized bionanocomposites of poly(lactic acid) (PLA). Moisture absorption tests were conducted for 30 days by immersing the samples in a distilled water bath at room temperature, and the amount of moisture absorbed in each time interval was measured. The rate of moisture uptake decreased by incorporation of C30B nanoclay and graft copolymer into fiber-reinforced PLA composites. Changes in the mechanical properties of composites in each time interval of moisture absorption were investigated using tensile and impact tests. Exposure to moisture caused significant drops in the mechanical properties. The morphological characterization of biocomposites during the aforementioned tests has been made using SEM, while bionanocomposites were analyzed by TEM. Further, this paper also reported the effect of accelerated weathering on the mechanical properties and the results are confirmed through SEM analysis. Biodegradation behaviors of PLA biocomposites and bionanocomposites have also been studied.
