Rapid growth in population and urbanization has created a huge demand for clean water and has led to rapid increase in the generation of wastewater. To meet this growing demand, it is essential to find technologies that will recycle the wastewater. Majority of the treatment technologies emphasize on the reclamation of wastewater. However, bio-wastewater which comprises of domestic wastewater, agro-wastewater, as well as wastewater generated from livestock, poultry farms, and swine farms comprise of a huge amount of nutrients. The present study portrays the resource recovery potential of bio-wastewater with respect to nutrients, water, and energy. The study also throws light on different treatment methodologies for treating these bio-wastewater along with its retrieval efficiencies. Use of different technologies can help in reclaiming 70–94% of nutrients from wastewater. Apart from electricity, the retrieved methane gas can be considered as an alternative for fossil fuel. The reclaimed wastewater can suffice the water demands of any building in the range of 20–25%. Benefit–cost analysis of these methodologies can help the policymakers with the formulation of regulations for implementing treatment plants at source itself to reduce the quantity of wastewater generated.
