In many countries, significant research has begun to evaluate the use of cassava as an ethanol biofuel feedstock. Under the Development Plan for Renewable Energy in the Eleventh Five-Year Plan in the People's Republic of China , the target is to increase the production of ethanol fuel from nongrain feedstock to two million tonnes, and that of biodiesel to 200 thousand tonnes by 2010. This is equivalent to the replacement of 10 million tonnes of petroleum. As a result, cassava (tapioca) chips have gradually become a major source of ethanol production.  On 22 December 2007, the largest cassava ethanol fuel production facility was completed in Beihai , with annual output of 200 thousand tons, which would need an average of million tons of cassava.  In November 2008, China-based Hainan Yedao Group reportedly invested US$ (£) in a new biofuel facility that is expected to produce 33 million US gallons (120,000 m 3 ) a year of bioethanol from cassava plants.
