Although sugarcane-trash (SCAR) energy represents a third of all sugarcane energy content, it continues to be the least studied of sugarcane agro-industrial residues. SCAR and bagasse moisture content were studied during the 2009-2010 and 2010-2011 milling seasons. It was determined that the percentage of dry and green matters represented 69% and 31% of the mass of SCAR, respectively. From an energy point of view, it was also established that there are no significant differences between the green and dry components of SCAR. Different analyses were carried out to estimate the High Heating Value (HHV) and Low Heating Value (LHV) of SCAR. In addition, meteorological factors and their influence on the moisture content of SCAR were studied during both milling seasons, and the variation in the energy content of SCAR during this period was controlled monthly. Regression models to SCAR moisture content forecasting were built and validated. The meteorological and geographical constrictions pertaining to the use of those models are discussed. Methodology to assess the feasibility of SCAR energy use was proposed.
