Kind of
treatment
Disadvantage
Advantage
Selected oil
No oil recovery
Thermalremediation
No oil recovery
Effective
Worry about flashback and secondary fires
Quick
Emit many hydrocarbons-related compounds
to air environment
Requires minimal but some specialized equipment
Considered oil
Less manpower needed
Threaten for human, surrounding recourse
and marine life
Cost-effective
Initial product is less viscous than burn
residue
Advisable on area covered with snow or ice
Advisable on open water area
Bioremediation
No oil recovery
All weather conditions
Selected oils
Less manpower needed
Less capacity of microbes to survive against
oil pollutants
Cost-effective
Depends on the indigenous
Mineralize oil to CO 2 and H 2 O
The presence of microorganisms at the site
Dependent on nutrient, available at the polluted site
