Development and application of a  Bioremediation technology for cleaning oil-contaminated soils


Abstract of research

RIPI has developed the soil bioremediation technology after laboratory and pilot research and has successfully applied this process in two field projects in industrial districts. In this process the potentials of indigenous microorganisms are exploited to biodegrade hydrocarbons and convert them into biomass and carbon dioxide. In effect, by applying this method, contaminated soils could be cleaned-up and recycled to their natural conditions.



Cleaning up oil-contaminated sites in petroleum industry and converting them into green landscape



Successful field design and application of bioremediation of 2000 tons of sludge-contaminated soil in Siri Island through landfarming

Bioremediation of 10000 tons of soils contaminated with drilling waste in Khangiran district throughthe  Biopile technology 

Applying phytoremdiation following microbial processing to change the area into green landscape

Domestic development of the bioremediation technology based on native microorganisms


Economic aspects

Bioremediation has economic and environmental advantages compared to physic-chemical methods

The operation cost of RIPI’s technology is lower as compared to technologies offered by other companies and it is applicable in Middle Eastern countries
