| Abstract |
This study presents a novel approach to oil-water separation by repurposing coconut fibers and expanded polystyrene (EPS) into a hydrophobic sponge. Spherical sponges were fabricated and coated with a polystyrene solution to enhance hydrophobicity. Quantitative analysis revealed a high oil absorption capacity of 7.6 g/g, with sustained efficiency over ten reuse cycles. A circular economy-aligned method for separating and recovering coconut fibers and EPS was validated. This research highlights the potential of waste valorization in sustainable technology development. The developed sponge offers a promising solution for oil spill cleanup and water treatment, with implications for environmental conservation and resource efficiency. |
