Why reuse urine for food production: my summary
- Motivation for valorising urine
- stop flushing gold!
- Energy consumption of water treatment plants, huge investments to maintain sewer system
- Drinking water to flush toilets: #!!!
- Same performance as conventional NPK fertiliser
- Available everywhere
- stop flushing gold!
- Risks and advantages, compared to conventional fertilisers
- Pathogens: major part removed after storage (high pH, NH4+ Temp)
- Heavy metals: less than in chemical fertilisers and in animal manure
- Micropollutants (pharmaceutical): yes, there is some risk: some metabolites of medicine may be taken up partially by some plant parts, it's very variable [ref: see Mendeley]. And apart from exceptions, MP aren't degraded simply in anoxic storage [VUNA publication] But in comparision, there's more antibiotica and other medicine found in animal manure, in average in Europe [ref!]
- Source-separation and collection
