Green nanotechnology

Green nanotechnology is the application of nanotechnology to improve the sustainability of environmental processes that have negative externalities. Additionally, it alludes to the application of nanotechnology-related goods to improve sustainability. In order to support sustainability, it involves creating green nanoproducts and using nanoproducts. Green nanotechnology has been defined as the creation of clean technologies "to minimise 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 creation of nanomaterials and products that do not harm the environment or people's health, as well as the creation of nanoproducts that address environmental issues, are the two main objectives of green nanotechnology. In order to create nanomaterials and nano-products without harmful components, at low temperatures, using less energy and renewable inputs where feasible, and utilising lifecycle thinking in all design and engineering phases, it leverages current ideas of green chemistry and green engineering. Even though green nanotechnology has numerous advantages over conventional approaches, there is still substantial disagreement over the problems that nanotechnology raises. In reality, the study of the impact of nanotechnology on the planet and all of its organisms is the main purpose of the science of eco-nanotoxicology. What will happen when nanoparticles sink into soil and water is still unknown to experts.
