Abstract

Current analysis investigates the co-generation system in the use of sugarcane bagasse, tips and straw for the sugar-alcohol sector, and discusses its large-scale viability. Simulations were undertaken to calculate electric energy with data from the literature and from databases of plants in the state of Pernambuco, Brazil. Results showed that the addition of leaf tips and straw in the process provided a 5% increase when compared to the co-generation using exclusively bagasse. Since income from bagasse as fuel reached R$ 13,104,000.00, straw was included to improve energy efficiency and increase the production of bio-electricity, with an estimate of R$ 15,600,000.00. Energy surplus may be sold to the region´s energy-distributor firm. However, during the last decades, sugarcane-energy plants have become self-sufficient to demands for thermal, mechanical and electrical energy. Selling surplus energy has recently become a possibility, with an increase in producers´ assets. Increase in the use of biomass has made Brazilian energy matrix cleaner. The idea that sugar and ethanol are the main products of sugarcane plants should be superseded. Bio-electricity should also be one of their products due to the plants´ great co-generation capacity and self-sufficiency.
