Bioremediation is the process of using organisms to deal with toxic wastes from such disasters as oil spills.

In a typical bioremediation procedure, microorganisms are introduced into the contaminated area.  They are often fed with nutrients that are meant to increase their growth and their ability to function.  The microorganisms consume the toxic wastes and metabolize them into less harmful substances such as carbon dioxide.

This process is very beneficial because, among other reasons, it can be used in hard to reach areas such as in groundwater deep underground.  However, it is not usable for all types of contamination.

Bioremediation is "the use of living organisms (primarily micro-organism) to degrade environmental pollutants or to prevent pollution through waste treatment". Bioremediation is emerging as most ideal alternative technology for removing pollutants from the environment, restoring contaminated sites, and preventing further pollution. This environment friendly technology is expanding range of organisms to be used to clean up pollution, and forms a vital component of the so called green movement of maintaining the nature,s overall ecological balance. Research projects are being modified to expand the range of microorganisms used for bioremediation. There is search for naturally occurring microbes that have better pollutant degradation kinetics.

Bioremediation is the process of using organisms to help clean up chemical and other pollutants. Some types of bacteria rely on specific pollutants as a food source.  This type of bacteria is released into the pollutant and as the bacteria digests the pollutant the pollutant is broken down into a less harmful substance.  Using Bioremediation is supposed to be a safer alternative and has been used to clean up oil spills.  At present it is a slow process and this method has been used for only around 5% of pollutant clean-ups.  Bioreactor landfills have been created based on the use of Bioremediation.  Aerobic and anaerobic bacteria is released into the landfills where they breakdown the disposed chemicals and products.  However, it has not yet been as effective as scientists would like it to be.  Because of earth’s expanding population and the increase in trash and debris as well as chemical production, there has been a lot of interest in finding a way to make this method more applicable in today’s society.
