One of the major objections to replacing gasoline with ethanol is that undertaking such a massive transition might put a strain on the world’s food supply, especially when it comes to corn. But according to Environmental Science and Technology Online, a new process has been developed which could take a chomp right out of this corn-supply issue. By simply pre-treating castoffs from corn production like cornstalks and switchgrass with hot water, the ethanol creation process is greatly enhanced making the use of the corn cob itself less vital. Indeed, researchers say this new treatment could double, triple, or quadruple ethanol yield, making corn more palatable in helping America both reduce pollution and lessen its dependence on foreign oil.
