Definition - What does Bioremediation mean?
Bioremediation is a technique of waste management in which organisms are used to neutralize or remove the pollutants from groundwater or contaminated soil. The technique stimulates the growth of organisms which use the contaminants as a source of energy and food. The technologies used in this technique of waste management can be basically classified as ex situ and in situ. Ex situ Bioremediation involves the removal of contaminants to be treated elsewhere and in situ involves the treatment of contaminants at the site.
Petropedia explains Bioremediation
Bioremediation can take place on its own or can only take place by adding fertilizers, oxygen, etc., to enhance the growth of pollution-eating microbes. The technique directly depends upon the organisms living naturally in groundwater and soil. The technique offers a good strategy for cleanup of some types of pollution but does not work for all pollution. It provides a technique of cleanup by encouraging the similar process of biodegradation as it occurs in nature. The main advantage of using Bioremediation technique is that it does not require much labor, equipment or energy instead it uses natural processes for cleaning up the sites.
