“…The BET (Quantachrome NovaWin ©1994–2013, Quantachrome Instruments v11.03) analysis was performed to evaluate the specific surface area, pore volume, and average size of the biochar samples. Prior to the analysis, the samples were degassed at a temperature of 120°C for 3 h. In addition, the surface area was calculated based on the nitrogen adsorption–desorption isotherm obtained from the Multipoint BET analysis, while the total pore volume and pore diameter were obtained using the Barette, Jovner, and Halenda (BJH) method 37,38 …”

This study utilized the top-lit updraft technology for the co-carbonization of waste biaxially-oriented polypropylene (BOPP) and almond leaves (Terminalia catappa) for the production of hybrid biochar, which was then further characterized. Biochar was also synthesized and characterized using the almond leaves alone, as it served as control for the study. The carbonization process, which ran for 100 min, gave a yield of 39.4% and 33.9% for biochar and hybrid biochar, respectively. FTIR spectra showed the presence of functional groups such as amine and carbonyl groups in the hybrid biochar. EDX results showed that the hybrid biochar contained about 57.3% carbon, in combination with other elements. SEM micrographs confirmed the presence of the plastic in the hybrid biochar. In addition, the hybrid biochar had a BET surface area of 366.8 m 2 /g and a pore diameter of 2.093 nm. DTA/TGA analysis showed that the presence of the plastics decreased the thermal stability of the hybrid biochar. This study supports the use of Terminalia catappa leaves as a reliable precursor for the synthesis of biochar and hybrid biochar.

“…Also many other researches on the mechanical behaviour evaluation were also reported [24][25][26]. In recent times, experimental investigation, theoretical prediction, waste plantain utilizations, and influence of Nano-/Micro-filler addition of various natural fibres with different filler and conditions were all studied, and revealed their impact in industry applications [29][30][31][32][33][34][35][36][37].…”

The development of newer materials necessitates bringing composite material as an alternative to conventional materials usage in engineering applications. An especially Natural Fibre-Reinforced Plastic (FRP) finds their role in the modern era. Before applying natural FRP in the industry, the investigation of mechanical behaviour and related application tests are essential for the better replacement of existing materials. The present work studies banana natural reinforced plastics with aluminium powder as to facilitate the use in an automotive body components. The composite was fabricated from banana fibre-filled Aluminium powder (Al-Powder) through a resin-hardener mixture by simple hand lay-up technique using compression mold. The samples were fabricated on a fixed weight percentage of banana fibres by varying Al-powder filler of 5, 10 and 15wt% to analyse the mechanical and physical properties. Four samples i.e., banana FRP composite (sample 'A'), banana FRP filled 5wt% of Al-powder filler (sample 'B'), 10wt% Al-powder filler (sample 'C'), and 15wt% Al-powder filler (Sample 'D') were used respectively. Tensile strength, compression strength, density, micro-hardness, water absorption percentage, and microstructure were conducted. The results showed that tensile strength has been increased by adding Alpowder up to 10wt%v as 33.07MPa. Beyond this 10%wt of Al-powder, tensile strength shows reduction. The density of composite samples filled Al-powder increases as the wt% of Al-powder increase. The microstructure of sample 'C' exhibits better than other samples. The compression strength 59.78MPa is observed in sample 'B' as higher than other samples.

The advantages that plastic‐based composites provide over epoxy‐based composites have catalyzed interest in the former in recent years. Polystyrene, a common packaging plastic, has been used for the production of composites. However, its hydrophilicity and curing duration are issues that undermine its commercialization. In this study, two fillers, calcined cow bone and kaolin, were introduced into a polystyrene resin matrix in varying concentrations through the hand lay‐up method. The composites were thermally cured at a temperature of 200°C for 3 h, after which they were characterized for their thermal and microstructural properties. DSC analysis revealed that the presence of kaolin improved the thermal property of the composite more than cow bone. The FTIR results revealed that the filler(s) were incorporated into the matrix via chemical reactions, as evidenced by bond breakage and formation. EDX results confirmed the incorporation of the fillers, with carbon being the most dominant element in the composites. It showed that the cow bone introduced elements such as phosphorus and calcium, while the kaolin introduced elements such as silicon and aluminum to the composite. SEM micrographs showed the presence of good interfacial adhesion between the filler(s) and the matrix. This study has shown that thermal curing is a viable solution to the shortcomings of polystyrene‐based composites and their commercialization.
