Municipal Solid Waste Status in Iran; From Generation to Disposal
Abstract The critical step of policymaking and planning for the local governments to select appropriate waste management methods and accomplish the required programs and projects, is comprehensive information on solid waste generation. Since in the last decade there has not been a comprehensive and integrated study for identifying waste management practices at a nationwide level, so this paper presents an overview of the current solid waste generation, characteristics and disposal method covering all 31 provinces of Iran based on available information and integrated waste management plans. The results show the average of solid waste generation (municipal and rural) throughout the country is 630 grams per capita per day. Although this is 10 percent higher than its level in the past decade, it is still lower than the global average per capita (740 grams per day). Solid waste composition in Iran comprises primarily organic, with 70 percent, followed by paper and plastic that account 7 percent, make up the waste stream. In addition, on average over 90 percent of generated solid waste in Iran is still openly dumped that increase healthy and environmental risk. So it is suggested that due to obtain accurate and reliable data, a comprehensive waste monitoring plan at the national level should be defined and waste composition and generation rate determined and updated through a standard method within certain interval time. According to the data of this research, planning and financial support for source separation can decrease environmental, economic and social problems in current solid waste management systems.
