The key drivers of increased wastewater generation are urbanization, industrialization and the growing population. While the conventional wastewater treatment systems focuses on meeting discharge limits, these processes are energy and chemical-intensive. Furthermore, the management of municipal organic solid waste and wastewater sludge is a growing issue. As a result, a paradigm shift from wastewater treatment as an end-of-pipe solution to a more holistic circularity-based system focusing on resource recovery is required. Therefore, the proposed research focuses on developing an integrated energy self-sufficient management system for wastewater and domestic organic waste in order to achieve the circular economy concept. Herein, we propose the separation of organic matter and water through a low energy-intensive direct membrane filtration, followed by recovery of value-added products such as energy, nutrients, biochar etc. This seminar will present a brief review of literature related to the feasibility of using Electro-conductive membranes (ECMs) for concentrating useful organic matter and will discuss the suitability of anaerobic co-digestion to produce bio-hydrogen, to make the system energy self-sufficient. In addition, a brief literature on electrochemical recovery of nutrients will be presented. Furthermore, the methodology to carry out the proposed works and preliminary results related to the performance of direct membrane filtration and bio-hydrogen generation will be discussed. Lastly, the sustainability of the treatment process will be evaluated by developing an assessment framework based on environmental, economic and social indicators.
