Hebecker ABSTRACT Present technologies for energy recovery from waste are reviewed. It is shown by examples that the conversion of mixed waste without pre-treatment in high-technology plants leads generally to lower energy recovery rates than the conversion of refuse materials with a low fraction of harmful substances due to pre-treatment. Plasma waste conversion offers favorable conditions for the conversion of the fraction of the waste materials charged with harmful substances in the pre-treatment. The development of a plasma technology for waste conversion from laboratory scale to a pilot plant is presented. Results of experiments showing effects of mixing and of dynamic phenomena are shown in detail. The potential for an increase of the average energy recovery from waste is derived from the presented results of the pilot plant operation.
