Os Resíduos da Indústria Sucroenergética: a Vinhaça Concentrada como Potencial Fertilizante

Abstract

The sugar-energy sector is one of the oldest Brazilian industrial activities. It was began with the colonization of Brazil and was focused on the production of sugar. After 1975 , with the beginning of Proálcool - National Alcohol Program , it began to be developed technologically receiving the extension of production and when production takes aim ethanol that would be used as an alternative fuel and replacement of oil derived fuels. We had an evolution in the agricultural sector in terms of development of new equipment , new technologies and , particularly , the development of new varieties of sugar cane. It is noticed that the development of the sector turned also in the development socioeconomic from regions and in his tip over while producing straight and indirect jobs. The growing production of ethanol, sugar and electric energy, has became out to be in bigger environmental impacts, due to the residues volumes that they started to produce. It is in this context that this work was developed, and since them the identified target the criterion for the use of the residues of the industry sugarcane pointing out the great quantity of vinasse as fertilizing potential from a program developed by a group of company of the sector and situated in the State of South Mato Grosso – Brazil. there were carried out bibliographic and field , that supported the growing of these dissertation and that made it possible: the identification of the produced residues and his forms of destination and the identification of alternative program of use of the great quantity of vinasse as fertilizer in the sugarcane crops as an ecologically sustainable practice.
