Energy, economic, and environmental assessment of the integrated production of palm oil biodiesel and sugarcane ethanol

The key objective of this study was to evaluate and compare, within the concept integrated biorefining, potential environmental gains life cycle, economic feasibility energy balance production bioenergetics from palm sugarcane. In context, research model developed in work involved several assessment techniques; terms assessment, tool used Life Cycle Assessment (LCA) Well-To-Tank perspective, which is based on LCA “cradle-to-gate” assignment method. performed using SimaPro v.8.0.3 software impacts were quantified IMPACT 2002+ On other hand, performance evaluation 1st law indicators. Likewise, fixed capital investment index estimate costs for entire system. Two different scenarios proposed order compare traditional systems with biorefinery. first conversion scenario (baseline scenario) consisted a oil extraction plant addition an ethanol sugar plant, concerning use fossil fuels all stages production. second (improved explored substitution sources as well recovery residual biomass more efficient systems. results indicated significant reductions 29.5% 29.1% global warming impact category when baseline compared improved scenario. Additionally, achieved reduction 2.1 g CO 2eq MJ ?1 (ethanol) 2.61 (biodiesel). presented better rates since it showed increase 3.82% efficiency system produced 106.32 kWh per ton processed raw material. Finally, considering Energy Efficiency, 83% observed case Renewability Factor 7.12 units. Integration also economically feasible; however, could be significantly through fiscal incentives founded use, enhanced yielding, improvements technologies. • Environmental biofuels cycle would reduced. Integrated biorefinery reduces greenhouse gas emissions due sustainability biofuels. has best ratio bioenergy produced. capable increasing by up 31%.
