Water and fertilizers are crucial components to the socio-economic development of the nation and sanitation is the basic need. In the manufacturing process of fertilizers, phosphorous and potassium are non-renewable critical resources that are 80 to 100% imported by India. One resource that interlinks the water-nutrients nexus with the sanitation is human urine. Urine contains about 98% water and remaining are nutrients (N, P, K). About 22% of the global phosphorus demand can be achieved through the recovery of phosphorus from human waste. It’s time to ‘reinvent the toilet’. The intention of the team is to develop an integrative-modular-onsite toilet-treatment system to protect our valuable water assets, reduce our customer’s operation costs & create new products from toilet resources in a simplistic approach, thereby unlocking the circular economic potential in sanitation.
