Close to the vicinity of the glorious city of Shiraz, the city of roses and great poets lay the first fertilizer industry in the country. Shiraz Petrochemical Company was founded with an initial investment of about 400 million US dollars in 1959, in 300-hectare land out of which 72 hectare is dedicated to infrastructures. The initial aim was to provide the fertilizer needs for the country. It now produces 1850000 tons/year of a vast variety of chemicals and petrochemicals and is counted on as a major petrochemical producer in the country. The major feedstock for the operating plants is natural gas, limestone, and salt. The natural gas source is from the main cross-country pipeline, while the limestone and salt are extracted from the adjacent mines. Water needed for the process, as well as utility purposes, is routed from the nearby dam.
