Bio-based material from fruit waste of orange peel for industrial applications

Bioplastics are plastics derived from natural resources like corn starch, biomass, sugarcane bagasse, and food waste. Unlike fossil fuel-based plastics, they are bio-degradable entirely or partially. Therefore, bioplastics are relatively less harmful to the environment. Cellulose and starch-based bioplastics are already used for applications like packaging, cutlery, bowls, straws. However, their cost and performance cannot match the conventional plastics. The present study was aimed to produce bioplastic from food waste material. As a result, orange peel is chosen because of its high cellulose content and good availability. The bio-plastic film from orange peel was produced using simple laboratory techniques. Its identification for potential applications is the new area of work. The developed film blends with glycerol as a plasticizer have indicated consistent and promising results. This has excellent strength, flexibility, and disintegration in soiling conditions, morphologically having a rough surface, and confirms the film's bio-degradability nature. Characterization methods such as Fourier transform infrared (FTIR) spectroscopy, Thermal gravimetric analysis (TGA), powderX-ray diffraction (XRD), and Scanning electron microscope (SEM) analysis confirmed that the developed material's physicochemical and surface morphology belonged to bio-based plastic. A simple, novel, and economic process are described in the manufacturing of bio-based plastic.
