Abstract:
The Brazilian ethanol and sugar production system is intensive in organic wastes generation. The main sugarcane production region (i.e. São Paulo State) is committed to increase the share of renewable energy into its matrix, including the promotion of biomethane as alternative fuel to natural gas. The present research assessed the potential biomethane production through the use of the organic wastes generated by the Sugarcane Industry of São Paulo State, Brazil. Total sugarcane milled and ethanol production were utilized to estimate the organic wastes generation of the Sugarcane Industry of São Paulo State during the 2012/2013 harvesting season, and together with biochemical methane potential (BMP) assays of filter cake, vinasse, bagasse and straw it was possible to simulate different scenarios where the produced biogas was upgraded into biomethane to further substitute the natural gas consumption of São Paulo State. The biochemical methane potential assays resulted in a biogas yield of 486, 647, 528 and 395 NmL/gVS, respectively for filter cake, vinasse, bagasse and straw. When these results are utilized to simulate the biomethane production, it was found that, if the entire filter cake generation was converted to biomethane, it could be substituted 10% of the total natural gas consumption in the State. In the same way, if the entire vinasse would be converted to biomethane, 17% of the natural gas consumption could be substituted. Meanwhile, if a fraction of the lignocellulosic organic wastes (¼ of bagasse and ½ straw) would also be used to biomethane production, not only the entire natural gas consumption could be substituted, but also additional energy (equivalent to 54% of the natural gas consumption in the year 2012) could be produced and exported from the State of São Paulo.
