N2 - The superstructure modeling of microalgal energy system including cultivation, dewatering, harvesting, extraction, biodiesel production, gasification and power output is achieved by using Aspen Plus® and experimental data. To address the multi-objective optimization (MOO) of microalgal energy system with respect to e economic cost and life cycle assessment (LCA), the mixed-integer nonlinear programming (MINLP) is solved by GAMS®. Bilinear relaxation is applied for the nonconvex constraints to reach the global optimum by using the piecewise bilinear relaxation convex envelope. Finally, a Pareto-curve graph for evaluating the trade-offs between environmental impacts and economic feasibility is successfully investigated.
