Development of biodegradable bioplastic film from fish scales
Abstract : Plastic is already an essential component of modern life, but its environmental impact has raised growing concerns. The purpose of this research is to turn fish scales into bioplastic film. Bioplastic is the most environmentally friendly plastic available today; it breaks down organically. Bioplastics have been produced using a variety of raw sources. Corn starch and fish scales are the raw materials employed in this work. Fish scales and corn starch are used to make the six different kinds of bioplastics. Three are fish scales, while three are based on corn starch. As a plasticizer, 99.95% glycerol is utilized. All of the produced bioplastics' physical and chemical characteristics, including their texture, colour, transparency, solubility in hot and cold water, and organic content, were examined. The best results were obtained with a mixture of fish scale powder and maize flour powder in a 2:1 ratio. After being exposed to organic waste for seven days, degradation was shown in the biodegradability test around 56% of the bioplastic broken down in seven days. The bioplastic is insoluble in base treatment (NaOH) and soluble in acid treatment (H2SO4), among other chemical compositions. Different films have varying thicknesses. Additionally, the transparency of film varies. While some are translucent, others are transparent. In contrast to cold water, these bioplastics dissolve more readily in hot water. The bioplastics that were created were made from natural, affordable, and environmentally beneficial components. Thus, a good substitute for synthetic polymers has been made possible by current research.
