Recent advances in lignocellulosic coconut fiber biocomposites and their industrial applications
Summary
This review paper summarizes existing research on turning coconut husk waste—normally discarded—into eco-friendly materials that could replace plastic in packaging, car parts, and construction. Since plastic pollution and microplastics are a growing concern for both the environment and human health, finding plant-based alternatives like coconut fiber could reduce our reliance on petroleum-based plastics that break down into the tiny particles now found in our food, water, and bodies. The research notes that scientists still need to solve some technical challenges (like making the fibers more water-resistant and durable) before these materials become widely available, but it points to a promising direction for more s
The depletion of petroleum resources and escalating plastic pollution have intensified the search for sustainable alternatives, positioning agricultural waste as a vital resource for eco-friendly material development. This review critically assesses the potential of coconut (Cocos nucifera) waste fibers emerged as a rich source of cellulose, hemicellulose, and lignin and as a renewable reinforcement for biocomposites. The primary objectives are to: (1) analyze the composition, structure, and key properties of coconut fibers; (2) evaluate advanced chemical, physical, and biological treatments for enhancing fiber-matrix compatibility emphasizing the of cellulose; and (3) explore their successful incorporation into biopolymer composites, highlighting improvements in mechanical, thermal, and morphological performance. The review comprehensively documents applications spanning biodegradable packaging, automotive components, and construction materials, demonstrating the fiber’s versatility. Furthermore, it identifies key challenges, including hydrophilicity, variability, and durability, which currently limit wider adoption. The review concludes by outlining a future research roadmap, emphasizing the need for advanced surface engineering, hybrid reinforcement strategies, standardized processing protocols, and comprehensive life-cycle assessments to fully realize the potential of lignocellulosic coconut fibers in advancing the next generation of sustainable materials.
