IPN Students Test 'Puribag,' a Dissolvable Plastic That Purifies Water

The student-led project remains in prototype testing with multi-institutional support.

Overview

  • The material is designed to dissolve in water and, when exposed to sunlight, purify the surrounding liquid.
  • UPIEM-IPN students Delia Guadalupe Robles Galeana and Cristian Martínez Domínguez lead the research effort.
  • Work has been underway for about 18 months, with the first bag prototype undergoing weight and temperature trials.
  • Collaborators include Universidad Autónoma Chapingo, Cinvestav, CICATA Unidad Legaria, and UNAM’s Institute of Biotechnology.
  • Developers target uses such as purifying rainwater and household greywater and reducing drain blockages, though performance and scalability have not been independently validated or commercialized.
