现阶段使用得最多的燃料材料是乙醇，这种材料可以提炼于甘蔗、甜菜与玉米(美国称为包谷)。
At present, the most widely used substance is ethanol, which can be made from sugar cane, sugar beet and maize (or corn, as it is called in America).
除了提炼玉米淀粉用以制造汽车使用的乙醇外，乙醇精炼厂将作物的剩余部分转为转为酒糟谷。
Besides extracting corn's starch content to be turned into fuel for cars, ethanol refineries convert the rest of the crop into distillers' grains.
第二代生物燃料原料改成采用生物量或者从草中提炼的纤维材料、玉米穗轴和干草、树木或者废弃物来提炼乙醇。
The second generation of biofuels converts biomass or cellulosic material from grass, corn cobs and stover, trees or waste into ethanol.
Eden技术公司是KTEC支持的一个项目，该公司开发出了从玉米的不可食用部分提炼乙醇的技术。
EdenTechnologies, one of Frahm's favorite KTEC investments, developed the technology to make ethanol out of the inedible parts of corn.
吉本斯解释，第一代生物燃料专注用玉米提炼乙醇，而大豆用来提炼生物柴油。他说“那是传统方法的改良”。
Gibbons explains that the first generation of biofuels focused on using corn for ethanol and soybeans for biodiesel. "that was the traditional approach," he says.
