Doing so pushed the urea, oxygen from the surrounding air, and hydrogen in the water to form solid percarbamide crystals. The crystals were then filtered from the water, ready for use as a fertilizer.

Urine is rich in nitrogen, which is important for plant growth, and now scientists have found an efficient way of utilising this to make human wastewater into fertiliser ...

Amid shortages in di-ammonium phosphate (DAP) and a general lack of manufacturing sector investments, one industry – urea – has actually seen significant installation of new production capacities and ...

Unfortunately, due to the fluid nature of liquid crystals, the polarity induced by ... the team presented a polarization fixation mechanism for a urea-based AP-FCLC system, where the materials ...
