“…PLA and sisal materials are sorted based on their composition, with PLA and sisal components separated from other materials. Once sorted, the PLA/sisal composites are shredded into smaller pieces to facilitate further processing [42,46]. Shredding helps in breaking down the materials into manageable sizes for subsequent steps.…”

“…It was suitable for high-performance applications needing heat resistance as well, thanks to its improved thermal properties. In addition to decreasing the quantity of non-biodegradable waste generated, the use of sisal fibres can strengthen the PLA material [46]. A more environmentally friendly substitute for conventional plastics made of petroleum might be provided by using natural plant-based ingredients [55].…”

PLA/Sisal hybrid composites have been used in cars and technical textile applications. When utilized in composites, 3-D-printed PLA layers can improve performance and homogeneity. The primary goal of this research was to use sisal and 3-D-printed polylactic acid (PLA) layers to develop a sustainable bio-composite. To enhance the bonding of sisal fibres with the PLA matrix, sisal fibres were given a sodium hydroxide treatment. This would improve the mechanical and thermal properties of composites. Sisal fibre (between 4 wt% and 8 wt%), epoxy concentration (between 85 wt% and 90 wt%), and PLA 3-D printing infilling percentage (between 90 wt% and 100 wt%) were the independent parameters. The Taguchi L8 orthogonal array design was used to make the composite samples. The changes in the amounts of PLA infill, epoxy matrix concentration, and sisal fibre content were considered for test sample development. The optimal settings for improving their tensile, flexural, and impact capabilities were determined by analyzing their signal-to-noise ratio (S/N). The PLA/sisal fibre composite showed a remarkable level of mechanical properties in Sample 8, surpassing those of the other samples. To improve mechanical and thermal properties, the appropriate values for sisal fibre composition, PLA infilling percentage, and epoxy concentration percentage were 8 per cent, 95 per cent, and 85 per cent, respectively. After testing, the tensile (293–295.4 Megapascal) (Mpa), impact (2.73–4.84 Mpa), and flexural strength (188.5–270.4 Mpa) results show that the new composite has better mechanical behaviour properties. Additionally, FTIR, SEM, and DSC experiments were run to examine the composite's structural characteristics. Using less volatile epoxy resin, a sustainable 3-D-printed PLA layer and Sisal fibre bio-composite were developed.

Developing biopackaging materials is a key for environmental, social, and economic sustainability. Herein, a newly designed gelatin composite film was prepared by incorporating biomass-derived aldehyde (BDA) and aminated graphene oxide (AGO), denoted as GBAF. FTIR, XPS, and primary amino group content tests demonstrated the successful preparation of AGO with different amino group contents. FTIR, XRD, and SEM analyses of GBAFs indicated strong interactions among AGO, BDA, and gelatin as well as the uniform dispersion of AGO in the film matrix. TG-DSC analysis showed that the GBAFs had higher thermal stability, and introducing AGO helped to improve the thermal stability of the GBAFs. WVP and gas permeability tests showed that the addition of AGO and BDA into the gelatin film reduced the transmission rate of water vapor, O 2 , and CO 2 , respectively. Additionally, the GBAF prepared from AGO with the highest primary amino content had the best tensile strength (2.45 MPa) due to the rigidity of AGO and covalent cross-linking between gelatin and BDA. Its tensile strength was much higher than that of the composite film without AGO (1.36 MPa) or BDA (1.59 MPa). Owing to its environmental friendliness, low toxicity, and sustainability, the as-prepared GBAF shows the potential to be used in sustainable biopackaging.

Maleic anhydride (MA) can function as both a grafting agent and a thermoplastic vulcanizate (TPV) agent in thermoplastic elastomer (TPE) blends of polylactic acid (PLA) and epoxidized natural rubber (ENR), depending on the degree of crosslinking. To validate the claim, a set of formulations with MA ranges from 0 to 2.0 phr was added to the PLA/ENR blend at different matrix blend ratios and compounding sequences. To distinguish the types of networks responsible for altering the blend’s phase and melt flow behaviour, various tests including mechanical, rheological, viscoelasicity validation, visual imaging, thermal analysis and spectroscopy testing of X-ray diffraction analysis (XRD) and Fourier transform infrared (FTIR) were conducted. The results revealed that, without the presence of MA, the blends behave as typical thermoplastic elastomers (TPEs). Meanwhile, the addition of MA enhances the tensile properties and modifies the blend microstructure, indicating the presence of a coupling effect in the PLA/ENR blend. With further inclusion of more MA inside the blends, the rise in crosslinking degree transforms the blend into a thermoplastic vulcanizate (TPV) compound. Interestingly, in the molten state, the TPV blends exhibit dilatant flow behaviour, which is in contrast with the shear-thinning flow pattern of PLA.
