The presentation focuses on microalgae cultivation through resource recovery from wastewater, with the objective of promoting symbiotic interactions between microalgae and bacteria. Before starting large-scale growth, the process moves through stages such as lab scale, pilot plants, prototypes, pre-demo, and demo scale setups. It emphasizes the knowledge and expertise required for successful scale-up at each level, showcasing the potential of this sustainable approach to resource recovery and wastewater treatment.
