This thesis is concerned with the biodegradation of oily sludges typically found at refinery sites as
waste residues from the refining of mineral oil. Currently these type of wastes represent
significant environmental risk. Current technology that addresses containment during treatment to
regulate the release of volatile organic carbons and reduction of the polynuclear aromatic
hydrocarbons in the sludge, is incineration. Incineration is a costly option and this research has
shown that the same treatment standards as incineration is achievable through bioreactor
treatment with the correct process and reactor design. [Continues.]
