Whereas the TCC® is based on transforming kinetic energy to thermal energy,the conventional thermal desorption technologies are heating the waste indirectly. The waste is placed inside a box, container or other storage facility and is heated by a medium outside the storage facility through the surfaces of the storage facility. In all such technologies the waste is heated gradually to the temperature required for the oil to evaporate, and the oil in the waste is under influence of high temperature for a long period of time, normally 30 minutes or more. In addition, the temperature of the heating medium in an indirect technology needs to be higher than the evaporation temperature of the oil, meaning that the oil is also influenced by a higher maximum temperature. For these reasons the output oil from the conventional technologies has a reduced quality and is normally not used as a component in new OBM.
