The Institute of Gas Technology (IGT) has been developing several techniques to improve biodegradation of town gas plant wastes such as multi-ring polynuclear aromatic hydrocarbons (PAH's). These techniques include the use of bioemulsifiers, chemical oxidants or biologically produced chemicals, PAH-degrading cultures developed by IGT through enrichment techniques, and appropriate co-metabolic and/or enzyme-inducing substrates. Depending upon the waste type and concentration, and geological characteristics of the site, a logical combination of any number of these techniques can be used to remediate the site. This paper discusses several liquid culture and soil treatment experiments conducted at IGT. Results show that PAH's in soils and in waters can be efficiently biodegraded by aerobic and possibly by anaerobic cultures and that chemical treatment and bioemulsifier applications enhance PAH biodegradation. This paper also mentions possible treatment scenarios consisting of various unit operations or remediation techniques. 9 refs., 11 figs., 2 tabs.
