“…In the FTIR spectrum, a peak located at 3007 cm −1 is observed for AG, which corresponds to the C=CH stretching vibrations. This peak is not present in AE, which indicates that a large part of the C=C unsaturations are present in triglyceride chains that have participated in the epoxidation reaction [30–31] . Peaks at 2954 and 2923 cm −1 were found in both oils, characteristic of asymmetric stretching vibrations of the methyl (CH 3 ) and methylene (CH 2 ) functional groups, respectively.…”

This study presents the characteristics resulting from the modification of the Melicococcus bijugatus jacq (huaya) with hexamethyl diisocyanate (HDI) and epoxidized avocado oil (AO) by the one‐step method within situ formation of peracetic acid (PA). HDI‐modified huaya starch and epoxidized AO present chemical characteristics that, according to the literature, improve the compatibility between polylactic acid (PLA) and starch when used to prepare biodegradable films according to the proposed reaction mechanism. The FTIR analysis confirmed that the grafting reaction of HDI onto the surfaces of the huaya starch granules and the epoxidation of the avocado oil took place. Peaks corresponding to vibrations of ‐NCO and ‐NH functional groups and vibrations of epoxy groups are present. The degradation profiles of the thermogravimetric analysis showed that more energy is required to initiate degradation after modification of the compounds. Scanning electron microscopy results showed effects on the huaya starch granules′ surface after the modification with HDI and a change in size. These results suggest compatibilization between the carbonyl groups, like those in the polylactic acid, the epoxy groups of the modified oil, and the isocyanate groups of the functionalized starch.

“…Numerous substances, including cellulose, hemicellulose, lignin, and others, make up the BPF and these components provide the strength to the BPF and the amount of fiber content affect the mechanical characteristics of its reinforced composites. 32 Following alkali treatment, BPF's surface area was increased (Figure 3), allowing more space for resin covering. Additionally, alkali treatment also increased the unprocessed BPF's tensile strength from 572 to 664 MPa.…”

The use of banana pseudo stems is currently acknowledged as a sustainable raw material that piqued researchers' interest because of their high cellulose content, and good to moderate tensile strength. In order to develop various batches of biodegradable composite, peduncle fibers from waste banana peduncles were isolated and then reinforced after mild alkali treatment with biodegradable soy resin, phenol‐formaldehyde (resole), and soy‐resole resins via thermoforming (compressing) method. Peduncle fiber reinforced soy‐resole composite exhibited maximum tensile strength of 43.5 MPa and flexural strength of 36.2 MPa as a result of strong interaction/bonding between functional groups of the two biomaterials used here. All composites were put through a water sorption test, which showed that they are fairly hydrophobic by nature since after 24 h, they absorbed 10.2%–28.2% of water. These composites proved to be both eco‐friendly and biodegradable, since they broke down easily in the soil after 60 days and all of the composites lost about 70% of their original weight. These composites are anticipated to be used as an alternative to environment threatening plastic in indoor furniture, packaging, and computer cabinets.Highlights Banana peduncle fiber was extracted from waste peduncle and used as reinforcer. The tensile strength of the composite was achieved as 43.5 MPa. The water absorption of composite was found 10.2% only after 24 h. After 60 days under soil burial, composite lost 70.8% of its original weight. Developed composites can be good alternant for non‐biodegradable thermoplastic.

“…In recent years, compared to the pots made up of petroleum-based or ceramic materials, seedling pots prepared from natural fiber have received more significant attention due to their biodegradation. Converting straw fiber into biodegradable seedling pots is an efficient agricultural waste management strategy, which can reduce the atmospheric and soil pollution resulting from straw burning or direct incorporation into fields. − Moreover, they can increase the survival rate of crops by avoiding root damage since the plants do not have to be removed from the pots before planting . However, some disadvantages such as low wet strength, poor water resistance and the resulting difficulty in transportation limit the wide application of straw fiber pots. − …”

Biodegradability of fiber-based bio-pot is not only determined by the properties of individual fiber and resin components but also significantly influenced by the behavior of the fiber−resin interphase. Herein, we fabricated bio-pots by utilizing bio-pretreated straw fiber and keratin-modified resin and clarified the interphase degradation mechanism by fiber and composite pot characterization, respectively. The bio-pots exhibited enhanced mechanical properties and hydrophobicity due to improved interfacial adhesion. However, the pretreatment reduced the hemicellulose content in the fibers from 30.06% to 15.84%, resulting in a decrease in the biodegradation rate of bio-pot. Scanning electron microscope and nano-indentation results elucidated that the reinforcing effect of resin on pretreated fibers diminished the interphase's susceptibility to moisture and soil microbials, leading to decreased mechanical loss during natural degradation (e.g., from degradation rate 44.0% for blank samples to 37.4% for 10 day pretreated fiber-based pots at the modulus). The significance of the results may improve bio-pot environmental sustainability and predict its life cycle through interphase degradation. Additionally, the results demonstrate the great future potential on recycling of waste natural fiber and development of composite bio-pot with controllable biodegradability.
