Biodiesel produced by microalgae was considered an ideal way to generate clean energy and bio-fixation on CO2, which is completely in line with the concept of carbon neutrality. But the harvest of microalgae is always the challenging part of the whole process. Till now several methods have been developed including, chemical coagulation/flocculation, auto and bio-flocculation, gravity sedimentation, flotation, electrical-based processes, filtration and centrifugation. Among these methods, biological methods are most concerned as they are environmentally friendly and cost-effectively. |
