Guizhou -- A Chinese energy company in the southwest province of Guizhou is awaiting its first harvest of more than 13,500 hectares of a "diesel tree", which will yield 15,000 tons of biodiesel oil for the energy-thirsty country.

"A green diesel oil field is taking shape in the vast mountain areas, and the oil-rich arbor is expected to become a reliable source of biofuel to meet increasing energy demand in China," said He Yuyuan, general manager of Zhongshui Energy Development Co. Ltd., which is based in the land-locked province.

After at least 30,000 tons of Jatroha L fruits ripen next summer, the company will extract their oil, refine it, and sell the biodiesel through the marketing channels of China Petrochemical Corp. (Sinopec), China's biggest oil refiner and petrochemicals producer, under a cooperation deal.

Jatroha, also known as Barbados nut or physic nut, is a perennial, drought-resistant shrub that produces large oily seeds. The oil can be used in candles, soap and now biofuel. The plant, whose seeds have an oil content of up to 62 percent, can adapt to almost any kind of climate or soil conditions and is considered an ideal way to tame the trend of rock desertification, which affects more than 20 percent of the province.

Zhongshui, a leading electricity supplier in Guizhou Province, has been cultivating the diesel tree in the infertile mountain areas of Luodian and Anlong counties since 2004.

Its new refinery, which cost 50 million yuan ($6.75 million), is scheduled to start operation at the end of this month, producing 20,000 tons of biodiesel every year using food waste and Jatroha L as the primary feedstocks.

With a technology independently developed by Guizhou University, the fuel is expected to meet Europe-IV emission standard, according to tests conducted by the labs of Bosch, DaimlerChrysler AG, Royal Dutch Shell Group and Volkswagen.

So far, more than 108,000 ha. of Jatroha L plants are thriving in the provinces of Guizhou, Yunnan and Sichuan, all in southwest China, The total acreage is projected to increase to 1.7 million ha. in 10 years.
