Abstract

The energy crisis is happening globally, therefore developing energy sources that are renewable and environmentally friendly is critical. Microalgae are third generation biomass, potentially as the feedstock for bioenergy generation. Harvesting microalgae can be done by using forward osmosis. However, the manufacture of these membranes generally uses conventional solvents which are toxic and harmful to human health and the environment. In this study we evaluate the potential for fabricating environmentally-friendly harvesting membranes for microalgae harvesting with forward osmosis through PRISMA protocol. The collected literatures were than synthesized into a narrative review. As a results, several articles were related to harvesting microalgae with forward osmosis using green solvent fabricating ultrafiltration, and microfiltration membranes were obtained. Some of the were using green solvent including Cyrene and methyl lactate. This review highlight a high potency of developing eco-friendly membrane with green solvent to be used for microalgae harvesting.
