TL;DR: In this article , the development of food packaging films based on citrus processing wastes has received increasing attention, and the developed films have wide applications in the preservation of aquatic products, baked food, fruits, vegetables and meats.
Abstract: Citrus fruits are one of the popular fruit crops around the world. However, the consumption and industrial process of citrus fruits yield a large amount of wastes, especially peels, seeds and pomace. Citrus processing wastes are normally used as animal feed or even discarded directly, which have caused serious environmental pollution and economical loss. Since citrus processing wastes contain numerous phytochemicals and bioactive components, they have good application potentials in food packaging sectors. In recent years, the development of food packaging films based on citrus processing wastes has received increasing attention. Food packaging films can be prepared by using citrus processing wastes in different forms, such as the direct use of citrus peel powder and the indirect use of active compounds extracted from the wastes (especially pectin, essential oils and seed extracts). The incorporation of citrus processing wastes or their extracts significantly alters the physical properties and enhances the antioxidant and antimicrobial activities of the films. The developed films have wide applications in the preservation of aquatic products, baked food, fruits, vegetables and meats. In this review, recent advances on the development of food packaging films based on citrus processing wastes are introduced. The preparation methods, physical and functional properties, and the applications of citrus processing wastes-based packaging films are summarized.

Abstract: With an intention to replace the synthetic non-biodegradable films in packaging applications, the polyvinyl alcohol (PVA) blended with green banana peel filler (GBPF), the biodegradable films were prepared by solution casting method with varying the concentrations of GBPF (5–25 wt%) in PVA matrix The bio films were characterized by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermo gravimetric analysis, transmissibility, FESEM, tensile test, film solubility and water absorption, water vapour transmission (WVT), soil burial test Based on results obtained, the changes evidenced in the FTIR spectrum of this PVA/GBPF biofilms suggest that strong hydrogen bonding is taking place due to interfacial exchanges of GBPF in PVA matrix The XRD results showed that crystallinity of bio films are greater than PVA Thermo gravimetric analyses predicted that PVA/GBPF bio films are thermally stable up to 300 °C The light is 45% for transmittance in the visible light region for the PVA/GBPF (25 wt%) bio film The FESEM micrographs of biofilms palpable that formation of good physical interaction and compatibility between polymer matrix and GBPF up to 20 wt% of GBPF in PVA Matrix FESEM results also confirmed that higher loading of GBPF (25 wt%) in PVA matrix, observed voids and agglomerations in film surface The PVA/GBPF bio films with 20% of GBPF gave the highest tensile strength and young’s modulus 445 MPa and 667 GPA respectively compared to other samples The elongation at break decreases with increases the GBPF in PVA Matrix up to 20 wt%The slight decrease in mechanical properties perceived due to higher loading of GBPF (25 wt%) with PVA matrix The solubility, water absorption and WVT of the PVA/GBPF bio films increased upon increasing the GBPF content The biodegradation test results discovered that he highest weight loss at 423% (25 wt% of GBPF) probably due to the hydrophilic nature of GBPF in PVA matrix On the whole, the present investigation confirmed that the PVA/GBPF bio films potential for possible utilization in active packaging applications attributable to its better mechanical, thermal, optical, water absorption and biodegradation properties

TL;DR: In this paper , the effect of adding gum arabic at levels of 0.5% and chromium oxide nanoparticles (Cr2O3 NPs) at level of 3% were optimized on orange peel-based films by response surface methodology, revealing a significant increase in water vapor permeability, weight loss, tensile strength, and Young's modulus of film samples by increasing the percentage of both gum and nanoparticles.
Abstract: In this paper, the effect of adding gum arabic at levels of 0–5%, and chromium oxide nanoparticles (Cr2O3 NPs) at levels of 0–3%, were optimized on orange peel-based films by response surface methodology. The obtained results reveal a significant increase in water vapor permeability, weight loss, tensile strength, and Young's modulus of film samples by increasing the percentage of both gum and nanoparticles (p < 0.05). Moreover, the addition of gum arabic and Cr2O3 NPs decreases the thickness, water-solubility, L*, a*, b* indexes while increasing the elongation to the breaking point. Furthermore, the moisture content of the film samples was decreased by the addition of nanoparticles, however, the addition of gum arabic increased this parameter. The obtained results from the morphology of the samples indicated an increase in both roughness and cracks by increasing the percentage of nanoparticles as well as creating a smooth surface with the addition of gum arabic. Besides, the results of Fourier-transform infrared spectroscopy revealed no new peak in the prepared samples, as compared to the control sample. The results of X-ray diffraction indicated that the addition of gum arabic and nanoparticles simultaneously caused the formation of new crystals and increasing the crystallinity of the films. Based on Thermogravimetric analysis results, the thermal stability of films containing the nanoparticles increased, as compared to the control sample. In the meantime, the addition of gum and nanoparticles increased the antimicrobial properties of the film samples, as compared to the control. Overall, those films created by the orange peel including gum arabic and Cr2O3 NPs could enhance the mechanical properties and water vapor permeability of the samples.

TL;DR: In the absence of waste segregation practices, recycling has remained to be an informal sector working on outdated technology, but nevertheless thriving owing to waste material availability and market demand of cheaper recycled products.
Abstract: In India, the collection, transportation and disposal of MSW are unscientific and chaotic. Uncontrolled dumping of wastes on outskirts of towns and cities has created overflowing landfills, which are not only impossible to reclaim because of the haphazard manner of dumping, but also have serious environmental implications in terms of ground water pollution and contribution to global warming. Burning of waste leads to air pollution in terms of increased TSP and PM10 emissions, which is equivalent to vehicular emissions at times. In the absence of waste segregation practices, recycling has remained to be an informal sector working on outdated technology, but nevertheless thriving owing to waste material availability and market demand of cheaper recycled products. Paper and plastic recycling have been especially growing due to continuously increasing consumption levels of both the commodities. Composting-aerobic and anaerobic, both the options are available to the country for scientific disposal of waste in future. However, country also needs something in terms of policy and guidelines to enable the municipal corporations to run the waste services efficiently.

TL;DR: Edible and/or biodegradable packagings produced from agricultural origin macromolecules provide a supplementary and sometimes essential means to control physiological, microbiological, and physicochemical changes in food products.
Abstract: Certain newly discovered characteristics of natural biopolymers should make them a choice material to be used for different types of wrappings and films. Edible and/or biodegradable packagings produced from agricultural origin macromolecules provide a supplementary and sometimes essential means to control physiological, microbiological, and physicochemical changes in food products. This is accomplished (i) by controlling mass transfers between food product and ambient atmosphere or between components in heterogeneous food product, and (iii) by modifying and controlling food surface conditions (pH, level of specific functional agents, slow release of flavour compounds), it should be stressed that the material characteristics (polysaccharide, protein, or lipid, plasticized or not, chemically modified or not, used alone or in combination) and the fabrication procedures (casting of a film-forming solution, thermoforming) must be adapted to each specific food product and usage condition (relative humidity, temperature). Some potential uses of these materials (e.g. wrapping of various fabricated foods; protection of fruits and vegetables by control of maturation; protection of meat and fish; control of internal moisture transfer in pizzas), which are hinged on film properties (e.g. organoleptic, mechanical, gas and solute barrier) are described with examples.
