Waste to Ethanol

摘要

The production of ethanol and its utilization as a fuel in vehicles has been touted as a means of lessening the world's dependence on fossil fuel while paying farmers for the excess corn they produce. North American laws currently require ordinary gasoline to contain five per cent ethanol. Almost all the ethanol used in gasoline comes through the fermentation of corn. The utilization of corn to produce ethanol has received harsh criticism from environmentalists and economists with claims that it drives up the cost of food, damages the environment, and is economically unsustainable because of government subsidizes.
