Nanoremediation is an innovative branch of nanotechnology that employed promising sustainable remediation strategies to control pollution from contaminated sites. Bionanoremediation is an important way of remediation in which nanoparticles are biologically synthesized using plant parts or microbes. This is an effective solution to mitigate the challenge of environmental pollution. Diverse kinds of heavy metal substances and chemicals associated with agriculture can be removed from contaminated locations using nanoremediation. Various technologies have been used in environmental remediation such as adsorption, absorption, chemical reactions, photocatalysis and filtration for the removal of contaminants from the environment. The big surface area to volume ratio of nanoparticles leads to enhance reactivity. Nano-materials are also involved in cleanup of various pollutants from diverse environmental locations such as air, water and earth. The combination of nanoremediation with other bioremediation technology has proved to be a valuable tool for the elimination of pollutants, as their synergetic effect can raise the effectiveness of the applied process/technique used for environmental remediation. Hence, sustainability assessments of nanoremediation methods are also used with particular attention paid to the health and environmental consequences.
