Oil spill contingency planning for the South African Coast undertaken by the Sea Fisheries Research Institute of the Department of Environment Affairs, has revealed that alternative disposal methods for oily waste need to be investigated in order to cope effectively and timeously with a major oil spill. Current techniques dealing with oily waste disposal are reviewed. These include recovery for re-use, stabilisation of oily waste, biodegradative techniques such as landfarming, co-disposal with municipal waste, stimulated biodegradation in ponds and direct burial, as well as burning and incineration. The suitability of these techniques, taking into account legal constraints, availability of facilities, financial considerations and environmental implications are appraised for South African conditions. Recovery for re-use is the optimum disposal option, but the location of refineries in South Africa, the limited facilities available for oil recycling and the inability of the industries to cope with large quantities or contaminated oily waste limit the recovery application. Stabilisation of oily waste for disposal as landfill or for use in civil engineering works requires further investigation with the South African construction industry. Landfarming techniques are suitable for the disposal of large quantities of oily sand or sandy sludge, but careful site selection is required to limit environmental contamination. Co-disposal of oily waste with municipal refuse is only suitable for limited quantities of oily waste and will reduce the life of the landfill site. Direct burial or burning of oily waste are shown to be environmentally unsuitable options, but under certain conditions they may provide the only practical solutions. Facilities for incineration of oily waste are limited in South Africa. The study shows that there is no easy solution to the disposal of large quantities of oily sludge. A combination of disposal methods will need to be used. Treatment of the oily sludge, for example emulsion breaking or separation will reduce the volumes, but costs could be prohibitive. A strategy is developed to provide the decision maker with a framework within which the decision process towards finding the correct solution for the disposal of oily waste following an oil spill off the South African Coast can be undertaken. 2016-02-26T07:16:03Z 2016-02-26T07:16:03Z 1991 Master Thesis Masters MPhil http://hdl.handle.net/11427/17266 eng application/pdf Department of Environmental and Geographical Science Faculty of Science University of Cape Town |
