“…XRD that consists of a mixture of B-and V-type structures has been previously reported [48][49][50]. It should be noted that most thermoplastic starches reported do not display such a distinct crystalline structure as is observed here [22,27]. In addition, there are a few sharp peaks which appear at about 15.05 • , 24.5 • and 26.8 • and deserve mentioning.…”

In this study, biodegradable starch film was developed from pineapple stem waste as a substitute for non-biodegradable petroleum-based films for single-use applications where strength is not too demanding. High amylose starch from a pineapple stem was used as the matrix. Glycerol and citric acid were used as additives to adjust the ductility of the material. Glycerol content was fixed at 25% while that of citric acid varied from 0 to 15% by weight of starch. Films with a wide range of mechanical properties can be prepared. As more citric acid is added, the film becomes softer and weaker, and has greater elongation at the break. Properties range from a strength of about 21.5 MPa and 2.9% elongation to a strength of about 6.8 MPa and 35.7% elongation. An X-ray diffraction study showed that the films were semi-crystalline. The films were also found to be water-resistant and can be heat-sealed. An example of a single-use package was demonstrated. A soil burial test confirmed that the material was biodegradable and completely disintegrated into sizes smaller than 1 mm within one month.

“…However, because starch, including banana starch, imparts poor flexibility and poor barrier properties to both water and air, some chemical addition and modification practices are often applied [ 117 ]. To improve the barrier properties of banana starch, Pongsuwan et al [ 122 ] utilize the banana inflorescence waste, which contains a high amount of fiber, as a filler for starch-based bioplastics which gave the bioplastics better physical properties, water, and thermal resistance. The addition of filler or banana starch modification in production, banana starch-based bio film was also reported by several studies [ 123 , 124 , 125 ].…”

Banana is a tropical fruit crop that is consumed at large, not only because of the quantity produced but also because it serves the calorific needs of millions of people. Banana is a potential source of high starch content (more than 60%). The application of starch for various purposes is dependent upon its structural, physicochemical, and functional properties. A native starch does not possess all required properties for specific use in the food product. To improve its application, starch can be modified physically, chemically, and enzymatically. Each of these modification methods provides different characteristics to the modified starch. This review aims to examine the chemical composition, granule morphology, crystallinity, pasting, thermal properties, and digestibility of banana starch, and discusses the various modifications and potential applications of banana starch in the food industry.

Creating environmentally friendly materials like polymer matrix composites (PMCs) enhanced with natural fillers has grown in recent decades. It supports the United Nations sustainable development goals (SDGs) by reducing the reliance on non‐renewable resources, minimizing waste generation, and promoting sustainable land and water management practices. This investigation assesses the viability of employing Elaeocarpus ganitrus (rudraksha) seeds as a filler (rudraksha seed filler [RSF] in environmentally sustainable composite materials. Various loading concentrations and sizes of RSFs were incorporated by hand lay‐up into polymer epoxy resin (ER). The effect of filler on the mechanical properties of composites was observed. Thermal properties of RSF/epoxy composites were investigated using thermogravimetric analysis (TGA) and Fourier transform infrared (FTIR). The 10 wt% 100‐mesh filler had the maximum tensile strength (TS) at 42.30 MPa and flexural strength (FS) at 87.4 MPa, surpassing other filler sizes and loading concentrations. Meanwhile, the highest impact properties have been achieved with 20 wt% of RSF with 0.436 J. The results of this study highlight the significant impact of filler type and concentration on the mechanical properties of the material. These findings offer valuable insights that may be applied to various industrial contexts. Furthermore, incorporating 10% up to 30 wt% RSF in epoxy composites has brought more thermal stability than virgin epoxy. It revealed that the RSFs possess higher decomposition temperatures than the epoxy matrix. RSF has a potential sustainable reinforcement in polymer composites and holds great promise for addressing environmental challenges and aligning with several SDGs.Highlights Interest in eco‐friendly materials, like polymer composites with natural reinforcements, has been increasing in recent decades. Rudraksha sees filler is lightweight with low moisture, high carbon content, and some mineral elements. The addition of Rudraksha seed filler has enhanced the tensile, flexural, and impact properties of the composites. Rudraksha seed filler possess higher decomposition temperatures than the epoxy matrix. Rudraksha seed filler has a promising future as a sustainable friction material for automotive brake pads.
