Nano may not be eco-friendly

A new research in the US shows that environmental gains derived from the use of nano materials may be offset in part by the processes used to manufacture them. The studies highlight the need for improved efficiency in nanoscale material manufacturing to reduce energy use, emissions, solid waste and the use of toxic input materials.

The study reveals the potential of environmental impacts from nano manufacturing to offset the benefits of using lighter nanomaterials. There is often a misconception that nanoscale production will necessarily be green and clean. Research shows that clean nanoscale production is not happening everywhere and it probably will not without a concerted effort by government and industry.
