Coconut husk: A sustainable solution for eco-friendly packaging applications

Abstract

This paper explores the use of coconut husk as an eco-friendly alternative for packaging. It details the composition, extraction, and processing techniques of coconut husk, emphasizing its abundance and sustainable sourcing methods. Key findings include the use of polyphenols extracted from young coconuts, achieving an 81% reduction in CO2 gas permeability and a 79% reduction in oxygen transmittance rate, demonstrating significant antimicrobial properties. The study highlights the creation of eco-friendly paper from coconut husk fibers and the development of bioplastics. Biocomposite films derived from coconut coir showed enhanced tensile strength and elongation, outperforming starch-based films. Environmental benefits include waste reduction and sustainable resource utilization, with the inclusion of 3% coir cellulose nanofibers in composite films notably improving tensile strength, elongation at break, and thermal stability. To sum up, this document highlights the importance of adopting sustainable materials in packaging and explores exciting possibilities for future studies, advancements in technology, and the widespread adoption of packaging solutions derived from coconut husks. This emphasizes the potential to drive a more environmentally friendly, sustainable, and eco-conscious packaging sector.
