India's population is expected to increase by 10% between 2030 and 2050 to 1.66 billion (United Nations, 2022). This surge in population increases the demand for freshwater, which in turn increases the wastewater (WW) generation in the country. As of 2021, 72,368 MLD (Million L/d) of sewage is generated in the country, of which only 30% is treated (Downtoearth.org, 2021). Most of the WW treatment facilities are operated at Tier-I and Tier-II cities, while rural regions are ignored. The non-availability of treatment facilities and lack of advanced resource recovery mechanisms has led to the discharge of 52,133 MLD of untreated WW into the water bodies . This untreated discharge of WW not only contaminates the freshwater resources, but also harms the ecology of waterbodies by causing eutrophication due to the presence of nutrients suspended in them. Thus, reducing the level of dissolved oxygen (DO) in water bodies . WW contains Nitrogen (N) and phosphorus (P) which are usually lost during WW treatment as sludge or discharged after treatment. Recovering and reusing them helps in achieving self-reliance and sustainability. Since N and P are critical components for plant growth, they are used as raw materials in fertilizer production. P is used as an energy source (ADP -adenosine triphosphate), while N is used for building DNA and RNA in plants . Ammonia (NH3) is a nitrogen-based fertilizer produced through the Haber-Bosch process from atmospheric N. Meanwhile, P is produced from phosphate rock, which is a non-renewable and limited resource. Moreover, the increasing demand for fertilizer might lead to exhaustion of the global P resources in the upcoming years. Thus, treatment and nutrient recovery from WW not only aids in preventing the contamination of freshwater resources but also abets recovering P thereby achieving sustainable development goal (SDG) 6 before 2030. Nutrient recovery from WW directly relates to the sustainability in four ways; i) reducing the production of synthetic fertilizers which makes the fertilizers industry enroute towards sustainability (SDG 2,12,13, and 15) ; ii) reduces the nutrient pollution in waterbodies thereby maintaining the sustainable ecology in aquatic systems (SDG 6) ; iii) efficient treatment of WW directly helps in reducing the over usage of freshwater resources (SDG 6); iv) mitigates CO2 emissions caused by WW treatment by production of value-added products (SDG 11) .
