Abstract:

Bioenergy deployment is among the most promising options to mitigate greenhouse gas (GHG) emissions. Such mitigation from biomass electricity depends on crop yields and residue recovery rates. Findings from Sugarcane Renewable Electricity (SUCRE) project in Brazil indicated that even considering site specific climatic restrictions, a large amount of straw can be recovered from the fields with low sustainability impacts and techno-economic feasibility. However, few has been done to assess the implications of sugarcane yields and straw recovery rates on Ecosystem Services associated with sugarcane electricity. We performed a georeferenced environmental assessment of sugarcane electricity, considering yield gaps and sustainable straw recovery. For that, we integrated Life Cycle Assessment methodology, Geographic Information Systems, process simulation and agroclimatic modeling. The georeferenced analysis made possible to map the best areas for sugarcane electricity production considering the maximization of Ecosystem Services, such as bioenergy production, mitigation of GHG emissions, and possible effects on water recycling, deforestation, and biodiversity loss. We believe this work can contribute to the assessment of sugarcane electricity potentials to the GHG mitigation targets assumed by Brazil in the Paris Agreement and in RenovaBio, and contribute to the Sustainable Development Goals 7, 12 and 13.
