Arthrospira maxima, a cyanobacterium commonly denominated Spirulina and known for its high nutritional content and rapid growth, presents a promising bioresource for such systems. This study explores a biorefinery model for Spirulina that maximizes resource utilization through innovative extractions and waste valorization approaches. By cultivating Spirulina using industrial waste media and recirculating growth resources, the model demonstrates significant reductions in water and nutrient use, aligning with circular economy principles. High-value compounds like phycocyanin and lipids were extracted using green methodologies, which reduce environmental impact compared to conventional methods. Additionally, residual extracted microalgal biomass was redirected to applications such as bioenergy and soil amendment, creating a zero-waste approach. The proposed model supports a transition towards sustainable bioeconomy practices, addressing both environmental and economic challenges. Future research may focus on genetic engineering and technological advancements to further enhance Spirulina’s biorefinery potential.engCircular EconomyFertilizerPhycocyaninResource EfficiencySpirulinaIconference object
