PROCESS FOR THE RECOVERY OF SOLID MATTER FROM GASES, LIQUIDS OR SOLID, RAW WASTES ABSTRACT Process for the treating of solid crude waste, which contains plastics as well as valuable and/or dangerous residual substances, especially, uranium and/or plutonium. The process involves treating the crude waste in a solvent, decomposing the plastics, especially in an organic solvent, and separating the insoluble residual substances from the plastic solution. The improvement involves comminuting the crude waste intended for treatment in the solvent into crude waste particles, and separating the crude waste particles which are not soluble in the solvent from the plastics solution. The insoluble residual substances are centrifuged out of the plastic solution. Sub- sequently the solvent is evaporated from the plastic solution, as well as condensed, and reused for the treatment of crude waste. The remaining plastic is solidified with the crude waste particles which are insoluble, separated according to the separation step, embedded in and/or with insoluble residual substances, centrifuged out and embedded in it.
