BIO-REMEDIATION TECHNOLOGY CASES IN IRLAND:<br />

‘NATURES SOLUTION TO OIL POLLUTION’<br />

Introduction<br />

Recent Advances in bio-technology have provided us with a natural solution to oil pollution<br />

in the environment. By massively accelerating the biological activity of naturally<br />

occurring micro-organisms (bacteria and nutrients). It is possible to degrade many types<br />

of organic pollution including oil, petrol, diesel and many solvents into harmless substance.<br />

On-going development, plus an increasing industrial acceptance of bio-remediation<br />

technology, has produced a natural alternative for cleaning up major oil pollution problems<br />

in-situ, both on land and water.<br />

This article describes the biological theory behind the implementation of bio-remediation<br />

technology. It describe some major successes achieved thus far and gives a view<br />

towards a cleaner future through the implementation of this environmentally friendly and<br />

cost effective technology.<br />

Whether as a consequence of accidental spillage or through long term disregard for<br />

the environment, the degree of contamination both on land and in water industrial centres<br />

around the world has left us with a legacy of pollution problems. Now that a more responsible<br />

attitude towards the environment is being rightfully taken by individual organisations,<br />

mainly because of stricter legislation and public pressure, changes in company policy are<br />

occurring. As a consequence there is a general requirement for improving the methods by<br />

which we clean up contaminated sites.<br />

Bio-Technology: A ‘Growth’ Industry<br />

Research conducted during the past 20 years has isolated specific micro-organisms (mainly<br />

bacteria and fungi) which are able to survive and grow in grossly polluted areas. Furthermore,<br />

it has been found that many of these species actually utilise certain toxic chemicals as<br />

a source of both metabolic energy and of the biochemical building blocks required for continued<br />

population growth. The toxic compounds are consequently being broken down into their<br />

constituent chemical component parts (usually non-toxic carbon dioxide, water and mineralised<br />

basic elements) as the population of micro-organisms proliferate.<br />

Research and Development<br />

Utilising this wealth of detailed knowledge on which of the potentially toxic organic<br />

substances are inherently bio-degradable has led to the development of modern bio-remediation<br />

technology. The efficient application of this technology relics on an ability to culture<br />

the exact species of micro-organisms which are known to be capable of breaking down<br />
