Phosphorus – bottleneck of life
„We may be able to substitute
nuclear power for coal,
and plastics for wood,
and yeast for meat,
and friendliness for isolation
– but for phosphorus there is neither substitute nor replacement“.
- Isaac Asimov (1920 bis 1992) –
First published 1959 (Life‘s bottleneck)
Limited availability

The traditional, closed anthropogenic P cycle
Once upon a time, there was an unbroken circle …
Soil <-> life balance …
- Wastewater/sewage sludge
- Biowaste
- Manure
- Meat and bone meal

The modern anthropogenic P „cycle“
Problems:
- Discoupling of food production and consumption
- Pollutants/contamination
- Inefficient use
http://www.nhm.ac.uk/researchcuration/research/projects/
phosphate-recovery/ceep11.htm
Need of mineral fertilizer
to compensate losses!
EU needs to import 975,000 t of mineral P!!!
Disruption of P cycle:
Urbanization
Industrialisation
Globalisation
Challenges for the future:
- Increasing P demand
- Decreasing quality of fossil P rock
- Limited availability
- Separation of nutrients from
pollutants for recycling

Benefits due to AirPrex unit:
- Reduced maintenance (no more clogged pipes), centrifuges run smoother
- Improved dewaterability of sludge (+ ~5% dry matter ) -> reduction of disposal costs
- Reduced chemicals consumption
- Annual cost reduction: 474,000 €

How to increase P-recovery rate from wastewater?
Project Goals
 Demonstration and systematic validation of technical processes at
full-scale facilities
 Systematic assessment and validation of the quality of obtained
recycling products with regards to plant availability of phosphorus
 Analysis of market barriers and market potential for novel recycling
technology and recycling products
 Development of strategies and recommendations for efficient and
wide-spread phosphorus recovery and market penetration from the
wastewater stream with regards to specific regional conditions ->
policy brief, guidance document
 EU-wide implementation of P recovery/recycling from wastewater stream
with respect to regional conditions and demands
www.p-rex.eu
Key deliverables
 Integral guidance document and policy brief
 Technical comparison of promising, available P-recovery/recycling technologies based
on real life data (including detailed factsheets for every process, BAT)
 Environmental impact and costs of compared technologies in relation to traditional
valorization of sewage sludge and mineral fertilizers based on fossil P rock
 Agreed methodologies for LCA and LCC to be used for other projects/assessment
studies
 Stakeholder workshops (market survey and regional conditions) -> broad base input
 Educative film and summer school
 Project website and e-market for P-recycling products

Market issues and synergies
 Feasibility of joint application wastewater / manure? Infratructure?
 What are the real market requirements besides the legal requirements (base line)?

Nutrient concentration
Pollutants

Market framework

Handling
Operational benefits?
Consumer concerns?
www.p-rex.eu
Example: AirPrex® Berlin-Wassmannsdorf
Raw product composition
 MAP ~ 60-70%
 Moisture: 10%
 Sand and organic matter: 10%
 Approved fertilizer “Berliner Pflanze”
 Sales price depends on package size:
 The smaller the higher … (2.50€/kg)
 Challenge and potential: improvement
of yield and quality
www.p-rex.eu
Outlook
 Struvite recovery is state of the art for P recovery/recycling (limited to Bio-P plants
and recovery max 50%)
-> already a growing market in terms of process technology, esp. when additinal
benefits for operator
-> still need to develop market for products (MAP, HAP etc.)
several thousand tons per year within the next 2 years
-> REACH!!!
-> whereas legal requirements are quite clear, the real end user needs are still
hidden
 If recovery >80% -> mono-incineration incl. ash treatment to obtain marketable and
useful products
 Infrastructure or technology applicable for manure?
-> what‘s better: separation and concentration of nutrients in solid phase and
then treatment of aqueous phase (or irrigation?)
-> or treatment of the manure in WWTP?

Outlook
 Still need to involve all stakeholders on equal eye level -> more efficient
collaboration, more impact -> that‘s ressource efficiency by means!
