GREEN Nano-Technology
Green nanotechnology refers to the use of nanotechnology to enhance the environmental-sustainability of processes currently producing negative effects. Here, the products of nanotechnology are used to enhance sustainability.
Definition
A broad definition of green nanotechnology is: Green nanotechnology is the development of clean technologies, "to minimize potential environmental and human health risks associated with the manufacture and use of nanotechnology products, and to encourage replacement of existing products with new nano-products that are more environmentally friendly throughout their lifecycle." The ability to eliminate waste and toxins from production processes early on, to create more efficient and flexible solar panels, and to remove contaminants from water is becoming an exciting reality with nanotechnology. designing nanoproducts for the environment and with the environment in mind is the essence of nanotechnology.

Goals
-producing nanomaterials and products without harming the environment or human health
-producing nano-products that provide solutions to environmental problems

Green Chemistry and Green Engineering priciplea are put to use to make nanomaterials and nano-products without toxic ingredients, at low temperatures using less energy and renewable inputs. manufacturing processes for non-nano materials and products more environmentally friendly using nanotechnology. This also comes under green nanotechnology.
Nanomaterials or products directly can clean hazardous waste sites, desalinate water, treat pollutants, or sense and monitor environmental pollutants and in the indirect form, lightweight nanocomposites for automobiles and other means of transportation could save fuel and reduce materials used for production;nanotechnology-enabled fuel cells and light-emitting diodes (LEDs) could save power.
