additional method for stabilization of toxic waste according to exemplary embodiments of the resent invention the method may include heating the waste in order to reduce the volume of the waste by evaporation volatiles in the waste and melting the plastic materials incorporated in the waste step 200 the waste may be heated by a controlled or partial combustion of the waste alternatively or in addition to the combustion of the waste the cell may be heated by oil gas or electricity afterwards pieces of toxic waste are encapsulated by melted plastic materials incorporated in the waste and the waste particles are embedded step 202 in the encapsulation substance or matrix the described method ensures that a direct contact with the waste and or leak of hazardous solid materials will be avoided in accordance with some embodiments of process 10 may be performed as a continuous process according to system 40 or as a non continuous or batch process it should be noted that in accordance with some embodiments of the present invention operating conditions of the heating and rotating cell might be controlled to optimize process 10 20 for a particular heterogeneous mixture of raw waste 40 for example operation parameters such as the mass flow rate of the waste the rotating speed of the cell and the temperature within the cell may be controlled and adjusted reference is now made to fig3 which is a schematic flow chart illustrating a method.
