In view of the situation and problems of hazardous waste utilization and disposal, the current situations of hazardous waste generation, storage, utilization and disposal in Inner Mongolia Autonomous Region were analyzed, and optimized countermeasures were proposed. The survey results show that inInner Mongolia Autonomous Region ,the amount of hazardous waste generated in 2019 increases by 16.94% compared with that in 2018. The generation of HW33 inorganic cyanide waste, HW11 refined (distilled) residue and HW48 non-ferrous metal smelting waste accounts for 83.7% of total waste. The area generating the largest amount of hazardous waste is located in the midwest, concentrated in industries such as mining, pharmaceutical manufacturing, and chemical materials. Hazardous waste disposal has problems such as unclear bases, weak utilization capacity of hazardous waste, and inconsistent between environmental impact assessment and daily management. In order to enhance the management level of hazardous waste disposal, it is suggested to optimize the disposal capacity, environmental impact assessment, diversified utilization and disposal, and information disclosure.
