Exploring the Viability of Circular Economy in Wastewater Treatment Plants: Energy Recovery and Resource Reclamation
Keywords:
Circular Economy, Wastewater Treatment, Biogas Production, Waste Reduction, Renewable Energy, Anaerobic Digestion, Nutrient RecoveryAbstract
This paper investigates the possibilities for applying circular economy principles at wastewater treatment plants (WWTPs) based on energy reuse and resource regeneration. Through the circularity of the traditional linear operations models, WWTPs can cut wastage and energy costs and recover valuable products, including biogas and nutrients. The study focuses on innovative technologies and practices that facilitate these changes and present technologies, such as anaerobic digestion and nutrient recovery systems used in the processes. Based on an analysis of relevant literature and case studies, the research assesses the circular economy's economic and environmental impacts in WWTPs. Based on research conclusions, combining energy recovery and resource reclamation processes improves sustainability, reduces costs, and helps preserve the environment. The relevance of this study is in presenting the benefits of embracing circular economy systems in wastewater management and providing knowledge to policymakers and relevant industry players to develop sustainable wastewater management systems.
