The significance and interest of printing green composites in three dimensions have recently grown, especially in light of the possibility of reusing waste to produce green fillers that can reduce the cost of biopolymers without compromising their processability and performance outcomes from a mechanical and environmental perspective. In the current work, the kernel powder obtained from the seeds of Tamarindus indica (TI) was added to polylactic acid (PLA) and extruded as a filament in the single screw extruder. It was then printed using an open source Fused Deposition Modeling printer and investigated for its density, mechanical, surface, and morphological characteristics. It was found that the composite performed better when the filler concentration was maintained at 2%, but when it went beyond that, the performance depreciated because of the rapid rise in material voids. When compared with a neat PLA matrix, 2% TI filler offered better overall strength, with increments of 12.64%, 19.87%, and 15.57% in tensile, compression, and flexural strength, respectively. The addition of TI filler was found to promote crystallization within the PLA matrix, leading to a higher degree of crystallinity which have contributed to higher strength. The morphological study demonstrated that the occurrence of uniform filler distribution and inter‐layer randomized bonding at 2% TI/PLA offered superior strength, whereas at higher TI concentrations it led to pullout and delamination. On the other hand, the hardness of the composite increased proportionally to the concentration of the fillers.

According to the Food Wastage Footprint and Climate Change Report, about 15% of all fruits and 25% of all vegetables are wasted at the base of the food production chain. The significant losses and wastes in the fresh and processing industries is becoming a serious environmental issue, mainly due to the microbial degradation impacts. There has been a recent surge in research and innovation related to food, packaging, and pharmaceutical applications to address these problems. The underutilized wastes (seed, skin, rind, and pomace) potentially present good sources of valuable bioactive compounds, including functional nutrients, amylopectin, phytochemicals, vitamins, enzymes, dietary fibers, and oils. Fruit and vegetable wastes (FVW) are rich in nutrients and extra nutritional compounds that contribute to the development of animal feed, bioactive ingredients, and ethanol production. In the development of active packaging films, pectin and other biopolymers are commonly used. In addition, the most recent research studies dealing with FVW have enhanced the physical, mechanical, antioxidant, and antimicrobial properties of packaging and biocomposite systems. Innovative technologies that can be used for sensitive bioactive compound extraction and fortification will be crucial in valorizing FVW completely; thus, this article aims to report the progress made in terms of the valorization of FVW and to emphasize the applications of FVW in active packaging and biocomposites, their by-products, and the innovative technologies (both thermal and non-thermal) that can be used for bioactive compounds extraction.

“…The huge accessibility of PLA makes it one of the favourite selections to replace petroleum-based synthetic plastics. 4 For the past few decades, the utilization of natural fibres in place of synthetic fibres for developing biocomposites has gained momentum. The advantages of natural fibres like no skin allergies to human body, low density, low cost, bio-degradability, recyclability, etc.…”

The current research work is aimed to study the potential of citrus limetta peel (fruit waste) as a novel filler in thermoplastic composites. Three different sizes of citrus limetta peel (CLP) fillers were processed and their thermal characteristics such as thermo-gravimetric analysis (TGA) and derivative thermogravimetry (DTG) were evaluated to investigate the degradation behaviour of each filler size under temperature. FTIR analysis of the CLP was also done to study the structure of inter- and intra-molecular hydrogen bonding in cellulose. The morphological study was also performed on both the outer surface as well as the inner surface of CLP in order to examine the surface characteristics. Based on the thermal characteristics of CLP filler, CLP-filled thermoplastic (poly-lactic acid) composite samples (by 20% weight percentage) were successfully fabricated using the injection moulding technique and were evaluated for their thermal, mechanical, and microstructural behaviour. It has been established that CLP fillers are amenable to processing using closed-mould processes such as injection moulding with fabricated products finding possible application in non-structural products, preferably in the particle board industry. As per the feasibility analysis, CLP fillers have the potential to be commercially exploited for product development.
