Diversificação das aplicações do bagaço de cana de açúcar.

Abstract

The growth in the sugar ethanol sector has powered the generation of large amounts of waste as bagasse of sugar cane, this biomass has been the subject of several studies aimed at your energy potential with regard to biofuel production, and however, your use is not restricted to this purpose. Due to the large amount produced and its physical and chemical characteristics, the bagasse is a vast field of use, including: production and generation of thermal and electrical energy, second-generation ethanol, animal feed, application of bagasse ashes in construction, production of briquettes, paper production, among others. The objective of this work was to do a survey of information about applications of the bagasse of sugar cane, in order to reuse and manageability, aiming to reduce the impacts caused with the disposal and increase the prospects of reuse. Storage of bagasse in the courtyards of the plants is one of the factors that contribute to the inefficiency of the use as a source of electrical energy, as humidity (50%) > is one of the main factors that reduce combustion. The current patterns of production and consumption of energy is based on fossil sources, which leads to local pollutant emissions, greenhouse gases and put at risk the long-term supply on the planet. It is necessary to change these defaults, encouraging renewable energies, and, in this sense, Brazil presents a condition quite favorable compared to the rest of the world, being the largest producer of the raw material. Whereas the infrastructure to consume any bagasse produced by cogeneration requires high investment with financial return unstable due to economic and political configuration of Brazil. Concluded that cogeneration have been held sufficient for the energy autonomy of the plants and the surplus bagasse (approximately 50%) stored and marketed at random, presents potential for diversification of bagasse, applications increasing the generation of social and environmental benefits.
