FIELD: utilization of organic sulfurous-containing waste. SUBSTANCE: organic sulfurous-containing waste is ground, added to fine-grain shale and heated up to 470-500 C. Said heating takes place by mixing waste with heated circulating ashes away from air. Thus obtained steam and gas mixture is fed for its purification and condensation. Hard carbonic residue is roasted and in ashes form it is returned to heating stage. It is used there as heat carrier and chemical absorbent. Thus worn tires, waste of industrial rubber, soil or sand being contaminated by hydrocarbon composition may be utilized. EFFECT: improved efficiency of the method. 4 cl
