Water Hyacinth-Derived Biopolymers as Reinforcements for Sustainable Fiber-Reinforced Polymer Composites
Abstract: Composting has gained significant attention for sustainable waste management and nutrient recycling. This study investigated the efficacy of water hyacinth (Eichhornia crassipes) as a composting material to produce nutrient-rich organic fertilizer. Water hyacinth compost inoculated with nitrogen-fixing (Azotobacter chroococcum) and phosphate-solubilizing bacteria (Pseudomonas putida) exhibited increased nitrogen and phosphorus content compared to uninoculated compost or cattle dung compost. Wheat grown with biofertilizer-enriched water hyacinth compost displayed significantly improved grain yield, …
