This research highlights the use of sugarcane bagasse fiber as a sustainable composite material for construction. It focuses on extracting fibers from bagasse using alkali treatment, which enhances fiber strength and bonding with polymers and binders. Treated fibers were used to produce composite panels with various binders, whose mechanical performance was evaluated through compressive and flexural tests. Results show that binder choice affects the mechanical, economic, and environmental feasibility of panels. Alkaline treatment improves fiber adhesion to binders, enhancing performance. Using locally available bagasse and materials reduces agricultural waste and promotes sustainable waste management and eco-friendly composite development.
