Solid waste management in tabriz petrochemical complex
Petrochemical industries, like other waste sources, are associated with numerous waste-related environmental problems. However, petrochemical solid waste is generally associated with more hazardous constituents, and accordingly carries a higher level of public health and environmental risk potential. In the last decade, the global economy has undergone radical changes that have had significant implications for the development of industrial operations (Hogland and Stenis, 2000; El-Fadel et al., 2001). Industrial development has generated complex wastes, a complexity not only due to the quantity of wastes, but also to their composition (Wei and Huang, 2001). Industries have traditionally managed their waste products by discharging them into the environment without previous treatment. This practice resulted in an increase of pollution and produced a negative environmental impact. The requirement for environmental quality resulted in a change of the whole concept of pollution control (Vigneswaran et al., 1999). Petrochemical industry is one of the most important and key industries in Iran. This industry generate large amount of wastes with high toxic compounds. There are some examples of petrochemical industrial in Iran that manage generated wastes. For example, Bandar Imam Petrochemical complex uses a method of organizing an industrial waste management system which is characterized by recovery, reuse, land filling and other waste management methods. Tabriz petrochemical complex (TPC) is located in the northwest of Iran and the west of Tabriz oil refinery (Fig. 1). Being located 1362 meters above sea level, it occupies 391 hectares. Major products of TPC include raw plastics like, polyethylene, polystyrene, Acrylonitrile Butadiene Styrene (ABS), etc.
