Peel eucalyptus can produce ethanol for cars

2. PeelsBiomass and Bioenergy – After studies that resulted in ethanol from corn, sugar beet, cassava and traditionally sugar cane, the second sentence of students of power engineering course at PUC Minas fuel extracted from eucalyptus bark. They believe that this procedure will be adopted on a large scale in the country.
