The information contained the types and amount of waste, temporary storage method, Discharge frequency, final disposal method, and the status of recycling and reuse. The results obtained from data analysis without considering uncontrolled industrial wastewater, show the annual production of Approximate 2,010,265 tons of waste; which about 1502 tons of this amount (according to available list in the Basel Convention), has classified under the title hazardous waste and about 12.42% of this type of waste was toxic. The share of liquid and solid physical states of the waste is respectively 59.87%, 13.77%. It should be noted that there is no temporary storage for about 20.29% of this waste. Reviewing the final disposal method indicates that about 28.66% of hazardous waste is discharged into the environment without any control.
