Chemicals, Vegetable Ghee and Cooking Oils

The vegetable ghee and cooking oil industry has registered a record increase to makeup for the shortage of ghee produced from milk. This shortage occurred because of the rising standard of living and the increasing population. From a production of 4000 tonnes in 1949-50, it rose to 695000 tonnes in 1999-2000.
The main raw material of the vegetable ghee and cooking oil industry is edible oil, which is not available in sufficient quantities locally. As a result, about 75 percent of the oil consumed by the ghee industry is imported. The market for ghee is widely distributed throughout the country, particularly in the urban areas. The ghee industry is also scattered throughout the country, with centers at Karachi, Nawabshah, Rahimyar khan, Bahawalpur, Haripur, Dargai.
Basic chemicals, like sulphuric acid, soda ash and caustic soda, are required by many different industries. The basic raw materials for these chemicals, like salt, limestone, gypsum and natural gas, can be found in Pakistan in large quantities. Coal and oil are found in moderate quantities. At partition, Pakistan had a fairly weak chemical industry, but a great deal of progress has been made since then.
Sulphuric acid is used in the production of soap, paper, textiles, fertilizers, iron and steel, petrochemicals. A number of sulphur processing plants have been established in places such as Karachi, Daud khel, Rawalpindi, Faisalabad, There has, therefore, been a steady rise in production. Caustic soda is also an important basic chemical, especially to the textile, oil-refining and soap industries. Processing plants have been established at Nowshera and Kala Shah Kaku near Lahore.
There are two soda ash processing plants in Pakistan located at Karachi and Khewra. Despite a steady rise in production, the demand for this basic chemical outstrips its supply, so much of has to be imported.
