EU Seventh Program







WA1: Phosphorus recovery from ash (lead BAM)

  • First large scale technical assessments of the technologies SUSAN, MEPHREC and LEACHPHOS: at least 80% P-recovery based on P-input in WWTP.
  • Return on experience of industrial scale units of ash processes and recommendations for optimization.
  • Comparative review of ash processes and identification and recommendations of best local framework for implementation.


WA2: Phosphorus recovery from sludge processes (lead FHNW)

  • Comparative field assessment of crystallization technologies: 10-30% P-recovery based on P-input in WWTP for sludge based processes, 30-50% P-recovery for sludge liquor processes, and 50-70% P-recovery for processes with leaching.
  • Return on Experience of industrial scale units including complete characterization of product quality and recommendations for optimization.
  • Comparative review of crystallisation processes and identification and recommendations of best local framework for implementation.


WA3: Phosphorus recovery through bio-solids valorization on arable land (lead IASP)

  • Demonstration of applicability of green polymers for sludge dewatering step
  • Identification and validation of suitable, reliable and affordable biological tests for efficient sludge and fertilizer monitoring.
  • Recommendation of efficient sludge monitoring strategies for legislation


WA4: Environmental, economic and risk assessment of P recovery options (lead KWB)

  • Assessment of toxicity and plant availability of secondary P-products: identification of Best Available Technique leading to fertilizer with lowest toxicity potential and good availability rate of phosphorus.
  • Definition of LCA and LCC guidelines for comparable assessments of P recovery processes
  • Comparative, technology-specific Life Cycle Assessment (LCA) of recovery paths: quantification of real environmental impacts of the technologies, and recommendations for optimization.
  • Quantitative risk assessment of potential hazards for humans and the environment: quantification of potential hazards resulting from agricultural use of the manufactured fertilizers.
  • Life Cycle Cost analysis of P recovery paths: conclude om the trade-off between costs and environmental performances for eacht technology.


WA5: Europe-wide implementation of phosphorus recovery (lead FHNW)

  • Analysis and proactive development of market potential for P-recycling products: offer / demand analysis and web-based e-market
  • Identification of regulatory and societal barriers: recommendations to European and national regulators
  • Business model case study and recommendations: pre-normative study sale price vs. product quality
  • Case-studies for Europe-wide implementation: Regional masterplans towards 80% P-recovery
  • Integral guidance document for phosphorus recovery and policy brief: to foster Europe-wide implementation of P-recovery from wastewater stream, support of decision makers and authorities in finding the optimal P recovery solution for their local conditions and actual needs


WA6: Management, dissemination and training (lead KWB)

  • Identification of any patentable innovation and encouragement of partners to protect and exploit know-how
  • Facilitate dissemination to European community and market countries in liaison with related initiatives and networks
  • Rising public and expert awareness for the project and the topic of phosphorus recovery and recycling through brokerage events
  • Facilitation of market deployment and exploitation of the technologies and P recovery/recycling concepts from wastewater
  • Ensure optimal administrative and scientific coordination between partners
