Green nanobiopolymers for ecological applications: a step towards a sustainable environment

Summary

This article explains how scientists are creating eco-friendly nanomaterials from natural sources like plants and crustacean shells to replace harmful plastic products. These green nanobiopolymers can break down naturally in the environment and are used in applications ranging from wound dressings to food packaging. The review covers how these materials are extracted and processed at the nanoscale to improve their properties for practical uses while reducing environmental pollution.

Background

Nanobiopolymers are biodegradable materials derived from natural sources that offer environmentally friendly alternatives to petroleum-based polymers. The exploitation of green nanobiopolymers is essential for minimizing non-renewable resource usage and maintaining a sustainable environment. These materials possess advantageous properties including abundance, biodegradability, and non-toxicity.

Objective

This review aims to discuss current advances and trends of biopolymers in nanotechnology, with emphasis on synthesis steps and structural characterization of green polymer materials. The article coordinates recent outputs and future utilization of nanobiopolymers for ecological applications with negligible environmental effects.

Results

The review identifies key green polymer materials including cellulose, chitin, lignin, and starch, detailing their sources, synthesis methods, and structural properties. Nanocellulose formation techniques, chitin extraction from crustacean shells, lignin processing methods, and starch nanocrystal production are comprehensively discussed with their specific applications.

Conclusion

Green nanobiopolymers represent cost-effective alternatives for circular economy applications and environmental sustainability. Strategic modification of natural polymers into nanoscale materials enables diverse industrial and medical applications while maintaining biodegradability and reducing environmental impact.
