In the objectives of the Development Strategy of new Uzbekistan for 2022-2026, it is noted that the volume of construction and chemical materials production should be doubled, the raw material base should be expanded by involving non-traditional non-metallic raw materials and secondary resources, non-waste technology within the "green economy" should be developed and introduced. Proceeding from the task set in the work methods of regeneration of composite sorption materials (CSM) after use in wastewater treatment, synthesized based on rotor slag of Djizakh battery plant are investigated. The recovery of CWM by thermal regeneration, which is the treatment of the sorbent by steam or gas at 110°-400℃, is shown. High temperature thermal regeneration is considered to be the most intensive method of sorbate desorption.
