Microalgal in the Production of Various High-End Value-Added Products Using Zero-Waste Biorefinery Approach

The zero-waste microalgal biorefinery presents a viable solution to the challenges of sustainable energy production and environmental impact. By emphasizing waste reduction and comprehensive utilization of microalgae biomass, this approach aligns with the urgent need for economic and sustainable biorefinery models. The capability of microalgae as a versatile source material for renewable biofuel and value-added co-products is significant, but economic viability remains a critical concern. The adoption of waste management principles, coupled with ongoing research into advanced conversion processes, waste mitigation strategies, and economic assessments, offers a pathway toward realizing a truly sustainable and efficient microalgal biorefinery. The ongoing pursuit of these advancements is essential for a successful transition toward carbon-neutral renewable energy and a more environmentally conscious biorefinery industry. Consequently, the multitude of extravagant additional value energy sources made from microalgae such as biodiesel, biogas, bioethanol, etc., is introduced in this chapter together with their complexities and futuristic perspectives.
