 Non-renewable at human time scale
 Spatially concentrated: geopolitical
dependency and tension
 Relatively low price, but price
volatility (2008 case)
 Lower P-rock quality:
● Decreasing P content
● Increasing impurities (e.g.
cadmium, uranium)
 Pollution and eutrophication

16. Transition towards sustainable P use
•remove non-essential P inputs (e.g. detergents)
•match P requirements more closely (precision
agriculture)
•utilise legacy P stores
Realign P inputs
•optimise input management
•minimise runoff and erosion
•strategic retention zones
Reduce P losses
to water
•avoid wastage
•improve utilization efficiency
•adopt integrated production systems
Recycle P
in bioresources
•recover P in societies' wastes
•produce fertilizer substitutes
Recover P in
wastes
•influence dietary choice
•define end-user P requirements
•re-connect crop and animal production systems
Redefine P in
the food chain

21. Data quality & monitoring challenges
 Data quality: trade > production > consumption > recycling
 Unclear definitions & not enough detail in data
 Public data is incomplete and inconsistent
 Data gaps for waste flows & (new) recycling flows
 Literature data mostly not recent and only specific base years
 Trade databases not available for all products/materials
 Data gaps requires data filling procedures & flow balancing
 Industry data not publically available, sometimes
commercially, but no peer reviewed
 Uncertainties for most data unknown
 Nutrient concentrations not monitored spatially & temporarily
 From quantity to quality, from theory to practise

22. WssTP RR WG 24th June 2015 - n°23European Sustainable Phosphorus Platform
DONUTSS
Data on Nutrients to Support Stewardship
- workshop Ghent with science and important all
stakeholders
- EU Commission DG GROW support
 identify data needs to support decision making
for industry & regulators
 define how and who to monitor & compare data
www.phosphorusplatform.eu/DONUTSS

23. WssTP RR WG 24th June 2015 - n°24European Sustainable Phosphorus Platform
Data systems on nutrient flows should be:
• Adequate, reliable, coherent and targeted to
support improved nutrient management decisions
• Available at regional, national and global level
• Specific to be useful for certain specific
stakeholders and sectors
• Covering both quantities of flows and quality
• Designed to target identification of key
management points

24. WssTP RR WG 24th June 2015 - n°25European Sustainable Phosphorus Platform
National policy initiatives on phosphorus
• Switzerland: waste ordonnance, proposal to make
obligatory P-recovery from sewage sludge and animal waste
ash (or separate storage pending recovery)
• Sweden: proposal to oblige 40% recycling of P & 10% of N
(including via agricultural valorisation of sewage biosolids)
• Germany: political commitment to make P-recovery
obligatory in sewage works
• Netherlands: struvite allowed to the market, in regulation
