An evaluation on the applications of some marine biopolymers

Marine Biopolymers




Marine Biopolymers, chitosan, gelatin, alginate


The environmental pollution caused by plastic waste is increasingly becoming a significant concern. As a result, the use of biodegradable plastics is gaining more importance. This study provides a detailed review of the applications of marine-sourced biodegradable plastics based on chitosan, gelatin, and alginate. Chitosan, a polysaccharide found in the shells of crustaceans, possesses properties that allow it to biologically degrade without harming the environment. These biodegradable characteristics make chitosan an eco-friendly alternative to traditional plastics. Chitosan is used in various fields such as food packaging, drug delivery systems, and wound healing materials. Gelatin is a protein derivative obtained from animal bones and skins. This material also possesses properties that allow it to biodegrade without harming the environment. Gelatin flexible nature makes it suitable for various applications in the plastic industry. It is used in areas such as food packaging, pharmaceutical capsules, and phototherapy devices. Alginate, derived from seaweed, is another polysaccharide that is biodegradable and environmentally friendly. Its high water-absorption capacity makes it an ideal material for applications such as food packaging and drug delivery systems. Marine-sourced chitosan, gelatin, and alginate-based biodegradable plastics stand out as eco-friendly plastic alternatives. The use of these materials can help reduce the environmental damage caused by plastic waste and contribute to a sustainable future. However, further research and development are needed on the industrial-scale use and recycling of these materials. In conclusion, marine-sourced biodegradable plastics have various applications and hold significant potential as environmentally friendly plastic alternatives. More efforts should be made in the future to increase the use of these materials and reduce plastic waste.
