Study shows bamboo ethanol in China technically and economically feasible, cost-competitive with gasoline

Green Car Congress

Now, researchers at Imperial College London have shown that bioethanol production from bamboo in China is both technically and economically feasible, as well as cost-competitive with gasoline. In its development of biofuel policy, China’s 10 th five-year plan (2001–2005) proposed a biofuel industry to utilize surplus grain stocks.
