At first, a heart-warming tale of synergy, biomimicry and multiple use. A lot to commend in what is being done here. Then a niggle appears; where are they getting the urine from? Sheep in a field will not normally produce urine in a way that is readily accesible for collection. Answer "The urine is collected by the fertiliser industry from farmyard waste and refined into pure urea," in other words, unless I'm mistaken, this is factory farm waste. Not so happy now.
All is not lost. actually the process should be applicable to any kind of urine refinement. So collecting the stuff from pubs and nightclubs should be a doddle ... !
