ENERGY CANE
Leal, Manoel Regis Lima Verde
Resumo:
Sugarcane has been developed and cultivated in different parts of the world, through the centuries, always as a source of food with sugar evolving from an expensive spice to become the cheapest source of food calorie. Its basic components, sugars and fibers, are treated quite differently in breeding programs in the world: the sugar components are valued in the selections of cultivars while the fibers of the cane stalk is limited, because of their effect on performance of mills and diffusers dragging sugars in the bagasse, the fiber of straw (leaves and tops) are not even evaluated. In the processing of sugarcane, sugar is the main product and ethanol and surplus electricity are by-products. In Brazil, this concept of the food industry for sugarcane has been slowly driven by the growing commercial importance of ethanol and, more recently, electricity. Ethanol has been produced consistently in Brazilian plants for more than a century, when it began to be part of the fuel options for the newly introduced car using the Otto cycle engines. Since the 1920s the National Institute of Technology (INT) has worked systematically to develop the technology of the Otto cycle engines operating on ethanol; the interest of the Brazilian Government at this time was to find an alternative to over-production of sugarcane, which constantly depressed sugar prices. Thus, in 1931 the requirement was instituted to blend 5% ethanol in all imported gasoline consumed in the country. This requirement was extended to all gasoline consumed in Brazil from 1938.
