Kampai! Japanese Make Ethanol From Straw
3 Juin 2013 - The truth about cars
Kawasaki Heavy Industries has developed “technology to produce fuel for cars from farm waste at a cost that is competitive with imported ethanol made from food products, such as sugar cane,” Reuters says.
Ethanol “can help reduce carbon dioxide (CO2), which contributes to global warming, but the cost of production and competition with food supplies tempers its appeal,” the wire says. A study showed that ethanol could be made from rice straw at a cost of $1.60 per gallon. Adding the costs for gathering straw waste, the gallon would cost $3.20 to make. That compares with $3.20 to $4 per gallon of imported Brazilian ethanol.
Not so fast, says Japan’s farm ministry, figuring that “ it would take about five years before commercial production of ethanol from non-food products would be economically viable.”
