Subject: Development of castor oil.
There are about hundreds of castor oil factories in China, of which only about 10% castor oil manufacturers start working; large processing plants have around 20; only nine plants have tens of thousands processing capacity. About 70% of Chinese castor oil processing factories in stop production or semi-shutdown state, because there are no adequate, high-quality raw material castor sources. At the end of the 1980s, China extends and built several large scale castor oil factories, each factory's total amount of annual output of castor oil are in 10 -15 thousand tons, total production capacity is about 55,000 tons per year.
The world's major markets of castor oil were concentrated in North America and Europe, of which the France, Britain, Netherlands, United States, Germany, five countries accounted for 61% of annual fuel consumption.
India castor oil used in making soap has about 1.6-1.8 million tons, the textile industry uses 2-3 thousand tons, chemical industries use 2-3 thousand tons, lubricating oil use 5-6 thousand tons, the rest for exporting. In Japan's castor oil use amount, paints accounted for 28.6%, the surfactant is 12.3%, cosmetic raw material is 8.2%, resin is 5.7%, hardened oil is 17.8%, sebum oil is 12.9%, others is 14.5%. Japan needs to import large quantities of castor beans every year; they are mostly imported from China, Pakistan, Indonesia, Sri Lanka, Philippines, Vietnam, Ethiopia, Brazil and other countries. Castor oil in the United States for the production of plastics and resins was accounted for 25.9%, fatty acids accounted for 12.7%, lubricating oil accounted for 6.3%, paint accounted for 23.7%, cosmetics (mainly synthetic waxes) accounted for 2.1%, others such as inks, surfactants accounted for 29.1%, these castor oils are imported from foreign countries.
Every year, the world needs 700 thousand tons of castor oil, convert into 1.6 million tons castor beans. Nowadays, gasoline resource was gradually reduced, transportation, live used gasoline was rapidly increasing, use gasoline as a raw material for synthetic material will be increasingly constrained in cost. And the United States study found that long-term exposure to polymers which synthesized by gasoline was harmful to human health. California and some other states have enacted laws and regulations for this, to restrict and gradually prohibit using synthetic resin in city buildings, interior facilities and human health-related sites and articles, which is polymerized from petroleum, natural gas cleaved into monomers raw materials, it makes castor oil's demand was rising sharply.
Castor cultivation in China is very commonly; there is no open planted regional division. South from Hainan Island, north to Heilongjiang is cultivated. Because castor hybrids with drought resistance, thin ridge resistant, saline-alkaline tolerance, well-adapted, simple to manage, less invest, high efficiency and other salient features, no matter grain field or hills, rocky land, saline-alkali soil and even around the house can be grown it. So anywhere in China can be planted castor.
