Sustainable Recovery of Nutrients from Urine
Most ammonia capture is done through the Haber-Bosch (HB) process, an energy-intensive technique used to produce fertilizer that accounts for 1-2% of the world’s annual energy consumption.

And because the technique recycles ammonia in a closed loop, the ammonia can be recaptured for reuse in fertilizer, household cleaners, etc.
