In 2025, researchers extracted superabsorbent gel from discarded diapers and tested it in sandy soil, where it showed water-retention potential similar to a commercial hydrogel

Scientists are investigating the potential of repurposing used diaper gel as a source of agricultural water retention. This material exhibits impressive water absorption capabilities comparable to existing commercial products. Given the high volume of discarded diapers, this superabsorbent polymer could be a valuable resource. However, challenges such as sterilization and cost-effectiveness must be addressed through further research before widespread application in gardens becomes feasible.
