 Context: Scientists at Stanford University are researching the use of sisal leaves to create a highly absorbent material that could replace cotton, wood pulp, and chemical absorbents in sanitary napkins.

  • The absorption capacity of the sisal-based material is reported to be higher than that in commercial menstrual pads.
  • The method developed by the researchers involves using a decorticator to mechanically separate the fibres from sisal leaves and employing a process inspired by termite guts to delignify the fibres.
  • The study claims that the process uses no polluting or toxic chemicals and can be conducted on a small scale, making it environmentally sustainable.
