“…The FESEM and TEM data were augmented by the FTIR data, which confirmed the presence of C=O, C-O-C, and O-H functional groups based on the peaks that were observed at 995, 1335, and 1644 cm −1 [38]. In other studies, the presence of carboxyl acid groups, phenols, and lactones was associated with the formation of inter and intra-molecular hydrogen bridge links [68]. The presence of these functional groups confirmed that there was extensive hydrogen bonding, which translated to higher chemical bonding between the starch molecules and the SPNFCs.…”

“…In contrast, flexibility/elongation at break is a key criterion in packaging applications. A compilation of different mechanical, physical, and chemical properties of commonly available agro-wastes showed that tamarind fruit fiber has the best mechanical properties (tensile strength of 1137-1360 MPa) [68], making it an ideal source of biopolymers for construction applications and a viable alternative to synthetic carbon. The data show that there is a relationship between the mechanical, physical, and chemical properties.…”

Production of Sustainable and Biodegradable Polymers from Agricultural Waste

Agro-wastes are derived from diverse sources including grape pomace, tomato pomace, pineapple, orange, and lemon peels, sugarcane bagasse, rice husks, wheat straw, and palm oil fibers, among other affordable and commonly available materials. The carbon-rich precursors are used in the production bio-based polymers through microbial, biopolymer blending, and chemical methods. The Food and Agriculture Organization (FAO) estimates that 20–30% of fruits and vegetables are discarded as waste during post-harvest handling. The development of bio-based polymers is essential, considering the scale of global environmental pollution that is directly linked to the production of synthetic plastics such as polypropylene (PP) and polyethylene (PET). Globally, 400 million tons of synthetic plastics are produced each year, and less than 9% are recycled. The optical, mechanical, and chemical properties such as ultraviolet (UV) absorbance, tensile strength, and water permeability are influenced by the synthetic route. The production of bio-based polymers from renewable sources and microbial synthesis are scalable, facile, and pose a minimal impact on the environment compared to chemical synthesis methods that rely on alkali and acid treatment or co-polymer blending. Despite the development of advanced synthetic methods and the application of biofilms in smart/intelligent food packaging, construction, exclusion nets, and medicine, commercial production is limited by cost, the economics of production, useful life, and biodegradation concerns, and the availability of adequate agro-wastes. New and cost-effective production techniques are critical to facilitate the commercial production of bio-based polymers and the replacement of synthetic polymers.

“…This may be due to the high lignin content in PJF which is known to be responsible for the thermal stability of natural fibers [8] . The lignin content in PJF is 17% [7] while other common plant fiber reinforcements like Flax, kenaf, jute, hemp and Sisal have a lignin content of 2, 9, 12, 10 and 9 respectively [37] .…”

A Bio composite comprising Prosopis Juliflora Fiber (PJF) and Poly Lactic Acid (PLA) was processed considering two particulate sized reinforcements, coarse PJF (avg. 15 µm) and fine PJF (10-50 nm). They were added individually at ratios of 10, 15, 20 and 25 wt% into PLA matrix. The composites were extruded and tested for mechanical properties. The addition of PJF resulted with an increase in the tensile, flexural and impact strengths of the polymer. Adding PJF to PLA showed a decrease in the hardness of the polymer. Water Absorption test showed an increase in water uptake with increasing fiber content. The most optimum ratio of PLA to PJF was found to be 80:20. The fine PJF reinforced composites proved to be superior over the coarse PJF reinforced composites at all stages of the research. FESEM and TGA were used to study morphology and thermal characteristics respectively.

“…Natural fiber/filler-reinforced polymer composites have attracted global interest in automotive, marine, structural, and biomedical applications, and so forth. [1][2][3][4][5] Natural fibers are the best alternatives to replace synthetic fibers, [1,2] as synthetic fibers are nonrenewable, nonbiodegradable with potential health hazards, leading to the development of ecofriendly natural fiber polymer composites. [3,4] Natural fibers/fillers have inherent benefits, such as relatively low cost, low density, biodegradable, recyclable, nontoxic and eco-friendly.…”

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.
