Justify with necessary logic “Biological clean-up methods can be cheaper than the conventional physical and chemical pollution treatments”.

In air, water and soil pollution causes many hazardous compounds. Various clean-up methods are applied to convert these hazardous compounds into non-hazardous chemicals. Such conventional methods use physical and chemical treatments of these compounds. To convert toxic compounds into biodegradable substances and in phases, into water and carbon dioxide, Biological clean-up methods have proved effective. Bioil-FC is one of such Biological agent. Bioremediation is also employed as a secondary treatment. It is a technique for environmental detoxification. To break down toxic organic compounds micro organisms are used. They convert them into less toxic ones. Such biological treatment systems are permanent in nature and require little maintenance.

Various techniques of boiling, pressure, reactions etc. used in physical and chemical methods. Various chemicals and systems used are expensive and requires technical know-how. Biological clean-up systems are less expensive and simple in comparison to these. Though research requires deep study for such methods, but they are less complex in their application. Moreover, Biological methods have shown effective results in many countries. But there are some limitations also, between a range of temperature they can be most effective. In spite of this, these methods are eco-friendly in themselves. Anoxic drains, limestone rock channels, alkaline recharge of ground water etc. used as natural mechanisms.

So, it can be easily said that, Biological clean-up methods can be cheaper than conventional physical and chemical methods in a long term calculations.
