A promising eco-material innovation has emerged from researchers affiliated with the Graduate School, Universitas Padjadjaran. Their study, published in Gels, introduces a sustainable cassava-starch–glycerol gel that forms a film capable of absorbing heavy-metal ions when applied to contaminated surfaces. Through FTIR analysis, the team confirmed polymer formation between cassava starch and glycerol. SEM and XRF analyses further validated that, once dried into a thin film on materials like glass, aluminum, or ceramic, the gel effectively binds and captures metal contaminants, forming amorphous compounds and indicating strong decontamination potential.

This innovative material aligns directly with key Sustainable Development Goals (SDGs). It promotes SDG 6 (Clean Water and Sanitation) by offering a renewable, biodegradable means for mitigating heavy-metal pollution from surfaces that may ultimately affect water quality. It embodies SDG 12 (Responsible Consumption and Production), leveraging inexpensive, widely available cassava—Indonesia’s staple crop—and benign additives, thereby reducing reliance on synthetic, environmentally detrimental sorbents. Additionally, it advances SDG 3 (Good Health and Well-Being) by providing a safer, non-toxic method for environmental contamination control—helping to minimize human exposure to hazardous metal ions.
