Wrapping up & thinking forward and of opportunities
Advantages of recovered commercial P recyclates can be:
✓ Defined/adjustable composition and fertilising efficiency (even precision farming)
✓ Effectively reduced contamination (health & safety, soil hygiene)
✓ Reduced nutrient losses to environment (avoid eutrophication)
✓ Are known in the market (demand, less bureaucratic burden)
✓ Create real value (not just disposal)
✓ Increase versatility of application (higher market potentials)
✓ Improve handling and increase application range (most are mineral nutrient concentrates)
✓ To help sustaining domestic jobs and making economy less vulnerable to imports
✓ Sludge/biosolids generated continously but nutrients used only seasonal (so continuous processing contributes to safety and better overall material flow management)

Challenges for technically recovered P recyclates

• Still missing level playing field (virgin vs. secondary materials, question of origin)
• Progress often needs legislative „motivation“ or pressure, clear and reliable messages
