Abstract: ABSTRACT The present invention relates to an eco-friendly leather alternative derived from cactus biomass, developed using a fully bio-based polyelectrolyte complex matrix reinforced with agro-waste nanocellulose. The composition comprises processed cactus biomass integrated within an alginate–chitosan polyelectrolyte crosslinked network, wherein ionic interactions between oppositely charged biopolymers form a stable and cohesive matrix without reliance on petroleum-based binders. Peanut-peel derived nanocellulose is incorporated as a nanoscale reinforcing agent to enhance mechanical strength, tear resistance, and structural integrity. The resulting bioleather exhibits improved tensile strength and durability while maintaining flexibility and biodegradability. The material is free from synthetic polyurethane coatings and supports circular economy principles through the valorization of agricultural waste streams. The disclosed composition provides a sustainable alternative to conventional animal leather and synthetic leather for applications in footwear, fashion accessories, upholstery, and technical textile products.
