Scientists have developed an innovative electrochemical technique to extract urea from urine, transforming it into a fertilizer while addressing wastewater treatment challenges.
- The new electrochemical process converts urine’s urea into Percarbamide, a crystalline peroxide derivative that can be used as fertilizer.
- It has achieved nearly 100% purity in extracting percarbamide from both human and animal urine.
- The extracted Percarbamide gradually releases nitrogen, enhancing crop growth and completing the nitrogen cycle.
- Urine contains essential nutrients like phosphorus, potassium, and nitrogen (urea), making it a potential natural fertilizer.
- An adult produces 450–680 liters of urine annually that can produce 4 kg nitrogen, and 0.3 kg phosphorus, enough to grow wheat for a daily loaf of bread for a year.
- It can help in achieving ODF++ status under the Swachh Bharat Mission-Urban (SBM-U) that involves solid and liquid waste management and the dairy sector to reduce GHG emissions.
