Indian-led team develops technique to use discarded face masks for carbon capture

New Delhi, Mar 22 (PTI) An international team led by a researcher from India has developed a new technique that uses discarded face masks to effectively remove carbon dioxide (CO2) from the air.

The researchers converted used face masks into porous activated fibrous adsorbents -- materials which capture molecules from a gas, liquid or dissolved solid to a surface.

These adsorbents possess multiple benefits such as a higher absorption rate, more capturing sites, higher adsorption capacity, and ease of handling compared to granular and powdered materials.
