Hi Megan,
I attended an interesting presentation at our biennial WISA 2018 conference in Cape Town last week. The paper was presented by Dr Dyllon Randall (University of Cape town). In short urine was collected in containers containing lime. Calcium phosphate precipitates (can be recovered as solid fertiliser) and the liquid portion is essentially sterilised due to high pH but still rich in nutrients and can probably be utilised with lower risk of pathogens and struvite issues. Unfortunately no further contact detail for Dr Randall, but I am sure WISA will be able to assist. Alternatively I can try and get more info if you are interested.
Regards

Many thanks Andre, I have been given contact details for him. I haven't heard of using lime to create a ppt, that is very interesting- thanks!
