Biodiesel production via transesterification of lipids would benefit the environment by producing energy from renewable resources. Lipids from microalgae can be effective feedstocks for biodiesel production, but the lipid extraction and conversion processes are costly for producing biodiesel from microalgae due to high moisture contents of the algal biomass. Furthermore, the dewatering process of microalgae before lipid extraction is one of the steps with highest cost in the microalgal biodiesel production. In this study, we developed effective dewatering method and biodiesel production process for Dunaliella tertiolecta. As a result, by using wet biomass directly as feedstock, the suggested process led to a 54% cost reduction in the biodiesel production, low lipid loss (0.87%, based on total lipid), and the same fatty acid methyl ester (FAME) production yield with conventional (dry route) biodiesel production method. |
