Summary
7.8/10Researchers developed an eco-friendly fertilizer nanocomposite using cellulose fibers extracted from pineapple peel waste, combined with biodegradable polymers and natural fertilizers. In field trials, the optimized formulation (F1) significantly boosted plant growth and improved nutrient absorption while reducing environmental pollution.
Key Findings
Microwave-assisted extraction of cellulose nanofibers from pineapple peel achieved 40.86% yield, outperforming high-speed blending at 33.21%
Formulation F1 with optimized cellulose nanofiber content improved plant height up to 182.4 cm and leaf area up to 530 cm² compared to controls
The nanocomposite demonstrated enhanced biodegradability, water retention, and controlled nutrient release in both conventional and vertical farming systems
Original Abstract
Food security is increasingly challenged by rapid population growth and limited arable land. Fertilizers are essential for boosting yields, yet conventional types often cause nutrient losses and environmental pollution. This study developed a bio-based controlled-release fertilizer (CRF) nanocomposite integrating cellulose nanofibers (CNFs) extracted from pineapple peel, biofertilizers, and biodegradable polymers to enhance nutrient efficiency and sustainability. CNFs were produced with a yield of 40.86% via microwave-assisted extraction and 33.21% via high-speed blending, with the former showing superior structural and physicochemical properties. The optimized CNF was incorporated into six CRF formulations (Control, F1-F5) containing 0-35% CNF. Among them, formulation F1 demonstrated optimal biodegradability, water retention, and nutrient release performance. Agronomic evaluation under both land and vertical farming systems confirmed that F1 markedly improved plant height (6.7-182.4 cm), leaf area (16-530 cm
Species Mentioned
The pineapple is a tropical plant with an edible fruit; it is the most economically significant plant in the family Bromeliaceae.
