| Abstract |
Because of rising global energy consumption, renewable energy sources have received increased attention. The use of algal biomass as feedstock for biodiesel production has been recognized for its relatively higher lipid productivity and lower impact compared to fossil fuels and other renewable sources. Yet, it faces challenges in its commercialization since fossil fuels are generally more inexpensive. The integration of various processes yielding different bioproducts has been encouraged to increase profitability and overall sustainability through algal biorefineries. Moreover, considering the goal to minimize waste, resource recirculation can be maximized to achieve economic and environmental sustainability. In this study, a multi-objective nonlinear optimization model for a closed-loop algal biorefinery simultaneously optimizing cost and environmental impact, integrating life cycle assessment to properly account for process unit environmental impacts, and incorporating quality degradation resulting from resource recirculation is developed. A case study is solved to demonstrate the validity and features of the proposed model. Furthermore, various scenarios are applied to understand the effects of environmental changes to the system. Results reveal important insights, which highlights the significance of quality as a driver of system behavior, and may be used by stakeholders to support the design and operations of algal biorefineries. |
