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

In a promising development for waste management and agriculture, researchers have successfully extracted superabsorbent gel from discarded diapers. This innovation tackles the challenge of recycling a common household waste product that is notoriously difficult to process.

When tested in sandy soil, the extracted gel showcased a remarkable ability to retain water, performing on par with commercially available hydrogels. This finding suggests a significant potential for the repurposed gel to improve soil moisture retention, a critical factor in arid and semi-arid regions.

The project's goal is to convert this challenging waste stream into a valuable resource for agriculture. By harnessing the water-absorbing properties of the gel, the technology could offer a sustainable solution for conserving soil moisture, potentially benefiting crop yields and reducing water usage in farming.
