Status of Remediation Approaches

Remediation states for the removal of pollutants from the environment. Remediation can be done in various ways such as by using waste biomass for sorption of pollutants or by living organisms like plants, microbes that cause degradation of pollutants. Bioremediation implies the use of microbes in the removal of heavy metals, industrial wastes and any other type of toxic wastes from the environment. These microbes may be used in viable and non-viable form, natural and modified form. Microbes used in natural form, faced many challenges related to their survival and tolerance to harsh environmental conditions.
