With the rise in waste production, we need methods to tackle them. The conventional methods just transfer the waste from one site to another. Bioremediation is one of the solutions for waste management which is environmental friendly, efficient and cost effective. It depends on the ability of living organisms to degrade the contaminants. Though intrinsic bioremediation processes are present, it is slow and has some drawbacks. Thus we use engineered bioremediation processes which depends on increased microbial growth and GEMs to get more effective and increased rate of removal of contaminants.

1. Introduction:

In the recent years, the disposal and management of waste has become a major issue. The conventional methods are expensive and are not very effective. Thus bioremediation is the need of the hour. Bioremediation uses living organisms to degrade or remove the pollutants from a contaminated site. It is defined as “Treatment that uses naturally occurring organisms to break down hazardous substances into less toxic or nontoxic substances” (EPA). The environment has the inbuilt tendency to degrade the waste which is known as intrinsic bioremediation. Since this is a very slow process we use technology to speed up the process and make it more
