“…Similar observations were made by Usman et al in the case of groundnut shell powder composites. [65] In the present study, the maximum hardness of 23.85 HV was recorded for the treated composite with 75 μm particle size. The possible reason for maximum hardness was due to the strong interfacial bonding between the particles and matrix with minimal void content.…”

The main objective and novelty of this study is to investigate the effect of particle size and alkali treatment on physical, mechanical properties of tamarind pod shell (TPS)‐reinforced epoxy composites. The treated and untreated composites were fabricated with different particle sizes with TPS content of 10 wt%. The mechanical, physical, and morphological properties of specimens were investigated. It was revealed that the density and mechanical properties of the treated and untreated composites increased with the decrease in the particle size; whereas, the water absorption percentage and void content decreased for the same. The treated composite with the particle size of 75 μm exhibited the maximum tensile, flexural, and compressive strength. Further, the multiscale finite element (FE) model was developed using the Digimat‐FE software to simulate the tensile behavior of composites with different particle size. The simulation results revealed that the stress concentration level was more in the vicinity of the voids, and the higher stress concentration was observed in the matrix phase with the increase in particle size. Also, it was found that the predicted results from the multiscale FE model showed a good agreement with the experimental results. The results suggested that the TPS filled epoxy composites have potential utility in the fields of automotive interior panels, particulate board panels, household goods, packaging materials, building partitions, and many other applications.

“…Commercial success of groundnut shells have not been reported although Kanayo et al [22] used ash form of groundnut shell in conjunction with silicon carbide as reinforcement agent in the development of Al-Mg-Si hybrid composites and significant improvement in corrosion resistant and mechanical properties was reported. Also, in our previous work [23], groundnut shell powder was used in both treated and untreated form to reinforced recycled polyethylene and the result showed improvement in mechanical properties with evidence of biodegradations. Plant fibers commonly used for the reinforcement of polymer matrix to produce biodegradable polymer composites includes kenaf, jute, flax, sisal, coir, and bamboo [14,[24][25][26][27][28].…”

“…Biodegradability experimentation of the samples was conducted by inoculating the GSP-recycled polypropylene composites with Aspergillus niger on a potato dextrose agar media and then incubated at room temperature (25°C ) for a period of 21 days as reported in the papers [23,30]. The samples were cut to sizes and placed with face on the surface of mineral salts agar in a petri dish without any carbon source.…”

In this study, groundnut shell powder (GSP) was used for the reinforcement of recycled polypropylene (recycled PP). The GSP consisting of two-particle sizes viz (0-250 μm and 250-420 μm) was partly treated with sodium hydroxide at room temperature and the GSP both treated and untreated were compressed and compounded with recycled PP to produce GSP-recycled PP composites. For comparison, recycled PP was equally produced as a control sample. The effects of GSP addition and sodium hydroxide treatment on recycled PP were investigated through the mechanical testing of the developed composites. The mechanical properties (tensile strength, hardness, and toughness) of the composites were evaluated and the tensile strength of both treated and untreated GSP-recycled PP composites is higher than the recycled PP and the treated GSP of particle size 0-250 μm having the highest tensile strength at 25 wt% GSP in recycled PP matrix. The hardness of the recycled PP increases with increasing content of GSP while the toughness decreases with increasing concentration of GSP in the recycled PP matrix. The water uptake of the GSP-recycled PP composites was equally studied, and the results revealed that the treated GSP-recycled PP composites has lower rate of water absorption as compared to untreated GSP-recycled PP composites Thermal stability and crystallinity of the composites and monolithic recycled PP were investigated, and it was discovered that the thermal stability and crystallinity of the polymer were enhanced with GSP addition. Morphological characterization of the selected samples through a scanning electron microscope (SEM) and x-ray diffraction (XRD) were equally done to validate the mechanical performance of the composites. Finally, biodegradability study on the composites and the control sample was conducted and it was found out that, the addition of GSP in both forms promotes the biodegradation of the recycled PP polymer. Such biodegradable GSP-recycled PP polymer composite materials are highly valuable for manufacturing food takeaway packages and some of the interior parts of the automobiles.

“…Recycling as a measure of addressing plastic waste pollution challenge is associated with the weakness of undesirable mechanical, thermal and other relevant properties of the recycled product [11]. Therefore, natural fibers have been harnessed as reinforcing filler in the polymer matrix and to enhance biodegradability of the recycled plastics in biocomposites production [12] Biocomposites are materials in which at least one of the components can be considered as bio-based. They are made from the combination of natural fiber (biomass) and a matrix with the resulting material having more desirable properties than either of the parent materials.…”

Valorization of post-consumer polythene water sachet and Parinari polyandra shell residue for composites production

Mitigation of the environmental burden associated with indiscriminate disposal of post-consumer low density polyethylene (LDPE) packaging material is receiving attention in recent times. There is a need to search for alternative reuse of the accumulating plastic wastes constituting pollutants in our environment. This work involves the preparation and evaluation of the bio-composite samples from post-consumer low density polyethylene water sachets and parinari fruits shell. Biocomposite samples of filler percentages 10, 20 and 30% were produced. The mechanical properties of the samples were determined as function of filler content and particle size according to ASTM standards and confirmed with SEM. The samples had desirable hardness strength of 4568.9 N/mm 2 and desirable biodegradability for 30% filler weight of particle size 4 mm. The biocomposite samples exhibited desirable impact (51.75 kJ/m 2), tensile (10.02) and flexural strength (18.23 N/mm 2) with the 10% weight samples. The findings in this study suggest that post-consumer LDPE wastes can be valorized by conversion to biocomposites using biomass wastes such as parinari shell as cheap value-addition material, providing a cheap potential waste management method for solving the global plastic waste crisis.
