"Though the cost of cellulosic ethanol is now around US $ 1 a liter, three to four times that of sugarcane alcohol, we predict it will halve in a decade due to technological advances and mass production. There's a great deal of development potential," says Lee. This is a current development trend internationally.
「雖然目前纖維素酒精的成本每公升在一美元左右，是甘蔗酒精的 3 ~ 4 倍，但當技術突破並量產後，預估未來 10 年會降低一半，極具發展潛力，」李堅明指出，這也是歐盟和國際間發展的共同趨勢。
