Scientists from National University of Singapore (NUS) have successfully converted paper waste into green nontoxic cellulose aerogels for the first time ever. Aerogels are most weightless solid materials in the world. They are also one of the finest insulation materials available.

Green Aerogels are:

  • ultra-light,
  • non-toxic,
  • extremely strong,
  • flexible and
  • Water repulsive.

By converting paper waste into biodegradable Aerogels it can be achieved and it is a simple, cost-effective and fast method.

Characteristic Features:

  • low thermal conductivity
  • Super high oil absorption capacity for example: 4 times higher than commercial sorbents.
  • Fabrication process uses 70 % less energy and produces fewer polluting productions into the air and water.
  • Traditional aerogels are mainly made of silica (non-environment-friendly process of manufacturing it).


  • It is perfect for fields such as oil spill cleaning.
  • We can also use it as heat insulation materials for buildings.
  • It also used as coating materials for drug delivery and as smart materials in biomedical applications.
  • It is biodegradable and environmentally-friendly material so it is also suitable for packaging industry.
