Castor mu yield in about 300 kilograms but advanced cultivation techniques Wu Dang yield in more than 1,000 kilograms with the reduction of oil resources, the search for alternative sources of energy has become the world's top priority. Castor oil is a renewable resource, most of the series of products from the oil can be obtained from the castor oil deep processing. Castor oil is considered by relevant experts as a renewable petroleum resource with great development potential.

The United States will be castor oil selected as one of the eight strategic materials France will be castor oil nylon 11 resin production technology selected as the country's top secret. Castor oil and its deep processing products nylon 11 resin, 12-hydroxy stearic acid and other widely used in medicine, aerospace, aviation, military, communications, machinery manufacturing, fine chemicals and other high-tech fields. The world's main importers of castor oil are France, the United States, Germany, Britain and the Netherlands and other industrialized countries, accounting for 61% of the annual consumption.

According to the survey of castor market at home and abroad castor shortage increases year by year demand increases year by year the price rises year by year, becoming the best-selling oddball products on the market. It is expected that in 2015 the global demand for castor oil will reach 1 million tons, equivalent to 2.4 million tons of castor oil. Global castor oil production is only about 600,000 tons, a big gap. There is currently no alternative to castor oil. Underground oil and natural gas resources are gradually decreasing, and the consumption of oil and gas for transportation and domestic use is rapidly increasing. Therefore, the demand for castor oil will increase dramatically. Therefore the price of castor oil in the international market has doubled. If it can enter the series of products of deep processing, its value will increase exponentially.

Because of the shortage of castor raw materials most of the enterprises are in a state of suspension or semi-suspension many enterprises need to import castor oil from India in large quantities. Therefore planting ramie is not only difficult to sell, but also essential to vigorously develop ramie cultivation. Compared with food crops, castor cultivation is easy, less investment and high efficiency. In addition, castor is adaptable, barren, disease-resistant, can be planted in the field, in front of the house, it is easy to master the cultivation techniques. At present, Malaysia's castor oil planting industry lags behind other Southeast Asian countries, castor oil planting and development enterprises and processing refineries are insufficient. But Malaysia's geographical and climatic environment is very suitable for planting castor, so I believe that the future prospects and advantages of castor planting in Malaysia is unlimited.
