Land contamination can result from a variety of industrial or commercial operations, such as chemical manufacturing/processing, concrete and asphalt production, petrol filling stations etc. As the presence of hazardous substances could cause significant harm to people, property or protected species as well as significant pollution of surface waters or groundwater, contaminated sites are regulated and closely monitored and the contaminated soils are treated if necessary to control the associated health and safety risks and adverse effects to the nearby environment.
Conventional remedial technologies such as soil washing, chemical oxidation and biopiling have been commonly used as “default technologies” for treating petroleum hydrocarbon impacted soils throughout Asia. While these technologies are mature and well-understood, the ever-growing urbanisation in Asia is exposing some inherent disadvantages of these systems and encouraging the exploration of other remedial technologies, such as small-scale low temperature thermal desorption.
In this presentation, a brief overview of these technologies will be made, together with several case studies of successful low temperature thermal desorption projects in Asia.
