Nanotech processing 'greener' than oil refining, study Using a method for assessing the premiums that companies pay for insurance, a team of scientists and insurance experts have concluded that the manufacturing processes for five, near-market nanomaterials -- including quantum dots, carbon nanotubes and buckyballs -- present fewer risks to the environment than some common industrial processes like oil refining. For two of the nanomaterials - nanotubes and alumoxane nanoparticles -- manufacturing risks were comparable with those of making wine or aspirin.
