Economic Viability of Nutrient Recovery From Wastewater: A Review Based on Current Technologies and Future Perspectives

ABSTRACT The depletion of limited natural resources and the need for strict environmental policies have catalyzed a shift toward sustainable and circular resource management, including the recovery of valuable nutrients like phosphorus and nitrogen from wastewater. This review evaluates the current state‐of‐the‐art technologies for nutrient recovery, focusing on their economic viability. By analyzing these technologies, the review article gives a novel perspective on their potential to reduce reliance on finite resources, create a sustainable, resource‐efficient societal network, and contribute toward the circular economy. Our current study highlights the economic potential and implementation challenges, offering a comprehensive overview of how nutrient recovery from wastewater can be a crucial strategy for closing a nutrient loop.
