    Through liquefaction, microalgae can be decomposed into four types of products: biooil, biochar, aqueous phase, and gaseous product [87]. One advantage of the liquefaction process is that aqueous phase that contains C, N, and P nutrients can be recycled and used in the cultivation of microalgae [88,89].
