Abstract

Nanoparticles are ubiquitous and have a wide range of applications that go unseen to the human eye. Nanomaterials exist in various external dimensions of fewer than 100 nm. The structural dimensions and variation in the size render crucial chemical and physical properties to the nanomaterials. Despite the nanoscopic size of nanoparticles, they tend to exhibit as many demerits as the merits. Nanomaterials should be disposed of with utmost care because of their drawbacks. Moreover, recycling nano ‘waste’ should be accounted for since it can reduce the intensity of toxic release into the environment. The main concern of nanoparticles is ascribed to the solubility and agglomeration properties of these particles. The waste generation begins during production and industrial/commercial use of the product. Nanowaste management is complicated because it is released in its purest form, as opposed to conventional waste. Accordingly, this review article addresses the effect of nanowaste on the vital components of the ecosystem, including human beings. It further gives an insight into a series of solutions to cope with nanowaste.
