The contamination of soil has been the result of commercial, industrial and military activities. Among the variety of the available technologies of organic contaminated soils, thermal methods ensure the greatest efficiency of the above 99%. Thermal technologies distinguish them through a very short remediation time and a possibility to treat a wide range of contaminants as compared to other treatment techniques such as bioremediation or solvent extraction. Microwave heating technique differs from conventional heating and has the significant advantage of greater time and energy saving, selective and uniform heating, as well as clean heating, it has been shown to be a potentially important technique for achieving the required environmental discharge limit. It was found that the microwave receptors within the material matrix (such as water) absorbed the bulk of the applied microwave energy. This energy subsequently being transferred to the oil in the form of heat, this was shown to cause thermal desorption. Results suggest that maximum heating rates or power loss densities could be achieved if the sample material had a high dielectric loss factor and was placed in the position of maximum electric field strength, and the treatment efficiency can reach as high as 84%. The costs of microwave treatment are shown to be as low as one tenth of conventional methods, which makes it an attractive method for scale up and eventual industrial implementation.
