Ethanol produced from rice straw is 99.5 percent pure, and does not compete with edible feedtsocks such as corn and wheat. According to Wang Chia-bao, the project's leader, "The straw is a secondary product, does not affect food supply and it will help our farmers' economy".
The only drawback of this process is its elevated price, currently estimated at $0.67 per liter, although Wang said that this amount could be cut in half in the near future.
