Based on technoeconomic perspective, in-situ transesterification of microalgae is more energy efficient than the conventional two-step process and thus economically competitive for biodiesel production. However, a comprehensive review on the effect of processing parameters towards conversion efficiency of microalgae biomass to biodiesel via in-situ transesterification is still lacking in the literature. Therefore, this review was intended to deliberate on fundamental understanding of this technology, including the effect of different reaction parameters towards biodiesel yield, technoeconomic impact of using wet paste microalgae, biodiesel composition profiles, and the state-of-the-art of the process. Besides, reaction kinetic and thermodynamics aspect of in-situ transesterification from microalgae were also discussed in detail. This review also provided in-depth information for process design and intensification under dedicated in-situ transesterification reaction condition for sustainable biodiesel production. Concurrently, research gaps in in-situ transesterification process was addressed for future study. © 2022 Elsevier Ltd publisher: Elsevier Ltd date: 2022 type: Article type: PeerReviewed identifier: Tien Thanh, N. and Mostapha, M. and Lam, M.K. and Ishak, S. and Kanna Dasan, Y. and Lim, J.W. and Tan, I.S. and Lau, S.Y. and Chin, B.L.F. and Hadibarata, T.
