This review explores the abundance of “natural waste fibers” in India, like jute, coir, sisal, pineapple, etc. These fibers are eco-friendly and non-abrasive due to their low cost, low density, acceptable specific properties, enhanced energy recovery, CO2 neutrality and biodegradability. Repurposing these fibers to strengthen polymers is an environmentally friendly choice. However, natural fibers tend to absorb water due to their high hydroxyl content, which negatively affects composite strength. Despite this, recent efforts have focused on combining waste natural fibers with plastics to enhance mechanical properties and reduce environmental impact. By leveraging the advantageous qualities of both materials, composite materials that offer strength, sustainability and cost-effectiveness can be created. The review emphasizes the potential of utilizing abundant natural waste fibers in India, particularly in polymer composites. It recognizes its eco-friendly and non-abrasive nature while addressing water absorption challenges. The fusion of natural fibers and plastics presents an opportunity for environmentally friendly and economically viable composites.
