New method turns plastic bags into high-tech materials.

 Scientists in Melbourne, Australia  have developed a new method for turning waste plastic bags into a high-tech nano material.

The process developed by University of Adelaide uses non-biodegradable plastic grocery bags to make 'carbon nano tube membranes' - highly sophisticated and expensive materials with a variety of advanced applications including filtration, energy storage and biomedical innovations.


Carbon nano tubes are tiny cylinders of carbon atoms, one nanometer in diameter (1/10,000 the diameter of a human hair).

They are the strongest and stiffest materials yet discovered - hundreds of times stronger than steel but six times lighter - and their unique mechanical, electrical, thermal and transport properties present exciting opportunities for research and development.

They are already used in a variety of industries including in electronics, sports equipment, long-lasting batteries, sensing devices and wind turbines.

The University of Adelaide's Nano tech Research Group has 'grown' the carbon nano tubes onto nano porous alumina membranes.

They used pieces of grocery plastic bags which were vaporized in a furnace to produce carbon layers that line the pores in the membrane to make the tiny cylinders (the carbon nano tubes).

The process is catalyst and solvent free, which means the plastic waste can be used without generating poisonous compounds.

Well now that's  some good news  for Plastic Bag manufacturers.
