Sugarcane bagasse is a waste generated in around the world in different quantities.It residue can be used to obtain different products under the concept of the biorefinery.Where the energetic technical, economic and environmental viability can be influenced by the scale of processing.In this sense, an analysis of the size of the biorefinery (scale analysis) was performed to determine the point of economic viability.In addition, an energy analysis was carried out, which allowed to identify the influence that has the processing scale on the energy changes presented throughout the process.As a result, it was possible to observe the importance of the analysis of the scale of a process for the determination of the point in which it is obtained not only an energetic but also economic viability.
