Engineer here. We arent talking about directly tossing it on fields. We are talking about having it be anaerobically fermented at high temperatures for about 30 days, with the biogas captured and used for energy.

the new thing to do then is burn the remains and recover the phosphate from the ashes, where certainly no biological threat remains

I’m curious how much phosphate we would be able to capture with this method?

I know it is a critical resource we are flushing away daily and -SHOULD- be doing this. Just like peak oil there is a concept of peak phosphorous.

  In the EU recovering phosphor from wastewater could cover about one third of the EU countries total phosphor demands.
  
  This is why the EU made tge strategic decision to have such recovery systems developed and built.
