  • 2. Phosphorus – bottleneck of life Limited availability Strategic resource „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)

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

  • 18. How to increase P-recovery rate from wastewater?  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 Project Goals  EU-wide implementation of P recovery/recycling from wastewater stream with respect to regional conditions and demands
  • 19. 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 (BWB) (BWB)
  • 20. P recoveredP recovered  Feasibility of joint application wastewater / manure? Infratructure?  What are the real market requirements besides the legal requirements (base line)? Market issues and synergies P recovered LEGAL framework Nutrient concentration Pollutants Plant availability Eco-toxicity Hygiene Market framework Price Purity (MAP?) Quantity Shape Handling Operational benefits? Consumer concerns?
  • 21. Example: AirPrex® Berlin-Wassmannsdorf  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 Raw product composition
  • 22. 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?
  • 24. Outlook  Still need to involve all stakeholders on equal eye level -> more efficient collaboration, more impact -> that‘s ressource efficiency by means! Science Policy Industry Policy Science Science Industry Industry Policy YES, TOGETHER WE CAN !!! I f w e w a n t t o ! ! ! P Platform
