Engineered Nanoparticles in Environmental Mitigation and Green Growth

The notion of green growth has emerged as a dominant policy response to climate change and
ecological breakdown. Environmental contamination is one of the important issues that the world is
facing today, it is always expanding and leading to the grave and harmful effect on the Earth.
Nanoparticles have a diameter less than 100 nm exhibit new size-dependent properties compared
with the bulk material. Engineered nanoparticles (ENPs) have unique characteristics in addition to the
high surface area-to-volume ratio, which may increase their toxicity relative to bulk materials. Due to
the high volume production of ENPs products such as carbon nanotubes, titanium dioxide, silver, zinc
oxide environmental exposure to these compounds is very common. ENPs have their unique
properties and applications in the areas of medicine, food & drink, construction, automotive, textiles,
energy, electronics, environment etc. To enable society to build and sustain a green economy, the
associated concept of “green nanotechnology” aims to exploit nano-innovations in materials science
and engineering to generate products and processes that are energy efficient as well as economically
and environmentally sustainable. The present book chapter is focused on the recent development of
the applications of ENPs in the environmental mitigation and green growth.
