Bioremediation is a method of waste management that entails the use of organisms to neutralize pollutants that pose risks to the environment and to human beings. It has become one of the most effective ways of cleaning polluted soil and water.
Bioremediation involves different microbes acting in sequence to complete the degradation process. The process may occur on its own or through the addition of fertilizer or oxygen that can help to encourage the growth of microbes. However, not all pollutants can be treated through the process of bioremediation; lead and cadmium are examples of pollutants that can't be treated this way. Pollutants that can be treated through this process include petroleum by-products, chlorinated solvents and methyl tert-butyl ether, among others.
