At the heart of the Microbial Remediation Process offered by Microclean Environmental is a Microbe that eats oil. The microbes are cultivated, not genetically engineered, to eat oil and other organic substances such as paraffin, grease, creosote and aromatic hydrocarbons. They convert oil, petrol and diesel fuel to harmless, naturally occurring products environmentally safe for human, animal, plant and aquatic life. This effective and cost competitive product is known as Oil Away. Oil Away consists of two main components; A mixed culture of naturally occurring hydrocarbon digesting microbes; A liquid formula with bio-catalyst and nutrients.


The process by which Oil Away is utilised is known as Bioremediation. Bioremediation is the restoring of a surface, object, soil or groundwater to a condition that is not harmful to plant or animal life. Site investigations using dedicated drilling equipment and scientifically qualified personnel will determine the vertical and horizontal plume of contamination in the soil and groundwater and the results thereof will provide the criteria upon which the Bio-Remediation treatment programme will be formulated. The product Oil Away will be introduced to the petroleum-based contamination via specifically chosen inoculation points. Through the use of groundwater pumps and specifically designed water heaters and bio-systems Oil Away is pumped throughout the total plume of contamination and re-circulated ensuring that the Microbes will track the migration path of the oil and digest the oil in situ. The water heaters and bio-systems ensure that the correct environment is maintained for the Microbes to promote growth and efficiency particularly during winter conditions.

A bioremediation programme will involve three main phases:

Phase 1: Free product recovery and groundwater filtration. Groundwater recovery wells are installed to interact with the contaminated groundwater to generate the necessary hydraulic conditions to mitigate contaminant migration and to allow the free product to be removed or filtered.

Phase 2: Bioremediation. Following the conclusion of Phase 1 the oil degrading bacteria and nutrients are introduced to the substrate and Microcleans specifically designed bio-systems are employed to maintain optimum environmental conditions for the microbes. As stated above the oil degrading microbes utilise the spilled oil as their food source and degrade the oil into environmentally safe by-products such as carbon dioxide and water.

Phase 3: Monitoring. Phase 3 runs in conjunction with Phase 2. Scientists employed by Microclean Environmental retrieve soil and groundwater samples for assessment and analysis on a regular basis to determine hydrocarbon degradation rates. Upon the conclusion of the remedial programme a full site compliance survey is carried out to confirm that the treatment objectives have been achieved.


Microclean Environmental adheres to the strictest clean up protocols and criteria to ensure that the hydrocarbon pollutants are remediated to the satisfaction of all parties concerned. Furthermore, Microclean's extensive knowledge of Environmental Law ensures that Local Authority mandates and other statutory obligations are adhered to.
