Urea is one of the major nitrogenous fertilizers (70 %) and the primary source of nitrogen supply for the plants. Apart from fertilizers, urea is used for the synthesis of resins such as melamine, and urea-formaldehyde resin , and as a diesel exhaust fluid which is used in diesel engines for selective catalytic reduction of NOx. Urea is synthesized industrially by Bosch-Meiser process that involves the conversion of CO2 and NH3 at a high pressure of 110 atm and elevated temperatures between 160 -180 °C. NH3, a primary raw material for urea production is manufactured by Haber-Bosch process at high temperatures (400 -500 °C) and high pressures (100 -200 atm) utilizing H2 from steam reforming process. 48 % of the global NH3 produced is used for urea manufacturing and the overall process to make urea is highly energy intensive and has a massive carbon foot print. It is desired to decarbonize urea manufacturing by synthesizing urea using renewable energy and readily available feedstocks via an electrochemical approach. Electrochemical synthesis of urea from N2 to CO2 is very attractive, but the process is very challenging due to the stable N≡N (941 kJ/mol) and lower solubility of N2 in an aqueous medium. On the other hand, N=O has lower bond dissociation energy (204 kJ/mol) in comparison with N≡N (941 kJ/mol) and hence it is less challenging to activate NO3 -in comparison to N2. Industrially NO3 -is manufactured from NH3, and electrochemical conversion NO3 -to NH3 would make sense only in the context of recycling the waste NO3 -. Synthesizing urea from the NO3 -and CO2 has a major environmental impact than utilizing NH3 and CO2 as the existing process involves 21 to 29 billion gigajoules of energy globally per year and 0.7 to 2.3 tons of CO2 emissions per ton equivalent of urea produced. 10 NO3 -is a major source of pollutants in agricultural run-off water, industrial processing plants, and ammunition waste. ANSOL (65 % Ammonium nitrate solution) is a major waste stream produced by Holstan army ammunition plant at a rate of 10 million pounds per year. ANSOL is extremely hazardous, and unsafe to store, and utilization of ANSOL in value-added products is one of the problems posed by the Strategic Environmental Research and Development Program (SERDP) of the US department of defense. ANSOL is usually sold to mining industries, but there is an inconsistent demand and the existing methods involve thermal degradation of ANSOL, which is inefficient and not environmentally friendly. NH3 can be recovered from ANSOL by stripping after shifting the pH of the solution towards the alkaline side. This results in a large concentration of NO3 -stream that is environmentally hazardous and it needs to be treated.
