Carbon Nanotubes from Old Plastic Bags: A major development

An "upcycling" method of converting waste plastic bags into nanotubes has been developed at the Argonne National Laboratory in Illinois. In this path breaking method, 1 gm pieces of high or low-densitty polyethylene (HDPE and LDPE) were cooked at high temperatures (700 degrees C) which broke down the chemical bonds of plastic and cause carbon nanotubes to grow on pieces of the cobalt acetate catalyst.
