Abstract:
In order to fulfill the lack of sustainable energy for the aviation sector, alternatives have been thought using sugarcane bagasse and straw in Brazil. The conversion of these lignocellulosic materials into bio-oil in biorefineries annexed to ethanol plants allows for a more efficient way of transporting the feedstock to sustainable aviation fuels (SAF) plants, which could be decentralized due to the transportation capabilities of the bio-oil. Greenhouse gas (GHG) emissions mitigation is fundamental to select locations for new plants. The objective of this study was to assess the candidate plants arrangement in the Brazilian state of Goiás that enhances GHG emissions mitigation and produce enough SAF to supply the demand of the Brasília airport. Results showed that the optimal arrangement of plants favored areas with high sugarcane yields and SAF plants were placed near the bio-oil plants, coinciding with regions far from the airport. This means that transportation had less impact than other phases, such as the agricultural phase, which had great impact on the overall GHG emissions, corresponding to 73% of the total. The final carbon intensity was 45gCO2e.MJ-1, less than its fossil counterpart, 89 gCO2e.MJ-1, showing potential for carbon mitigation.
