Microalgal biorefineries in sustainable biofuel production and other high-value products

Microalgae has been emerging as a promising solution against the backdrop of the global need for sustainable, eco-friendly alternatives. This review article analyses the use of photosynthetic microalgae as an important resource for sustainable biofuel and high value bioproduct production, emphasizing the potential of self-sustaining microalgae biorefineries. A closed-loop, integrated multi-product producing microalgal biorefinery approach could significantly reduce the indicated negative environmental and energy impact from standalone microalgal biofuel generation. The economic feasibility of these biorefineries is linked to their recovery rate, improved by integrating various unit operations as well as…
