Development and Preliminary Evaluation of Banana Stem Fiber-Based Biocomposite Using Natural Okra Mucilage and Rice Gum Binders

This study develops a novel bio-composite from banana stem fiber and coconut particulate filler by the use of two food grade natural binders such as okra mucilage and rice gum paste as fully plant based alternatives to synthetic resins. Through direct qualitative comparison, okra mucilage was found superior to rice gum paste in rigidity, surface quality and fiber binder adhesion. It’s also retaining strong adhesion under water and oil exposure. The work establishes a locally sourced low cost and biodegradable composite system aligned with circular economy principles and UN SDGs 9, 12, and 13 laying the foundation. This is a continuous process, the strength of the newly formed composite is yet to confirm, however the composite shows better adhesion.
