Abstract: 
This study investigates the synthesis of porous biodegradable materials from rice bran and pineapple waste to determine their potential as carriers for slow-release NPK (Nitrogen, Phosphorus, Potassium) fertilizers. Through gel formation, solvent exchange, and carbonization; agro-waste gets converted into highly porous materials. A further examination of these materials demonstrates their adsorption capability and efficacy in progressive NPK fertilizer release. Experimental results show that both rice bran and pineapple waste-derived materials are effective slow-release fertilizer carriers. However, comparative investigation shows that rice bran-based material has better slow-release properties than its pineapple waste-derived counterpart. Here we also include the kinetic study of the release rate of NPK fertilizers which turned toward a Pseudo-zero order of release rate. This study emphasizes the necessity of repurposing agricultural byproducts for sustainable material synthesis, which contributes to the advancement of green chemistry and provides eco-friendly fertilizer delivery systems.
