Mission: Increase synergies of resources use efficiency and
environmental sustainability within circular economy

3.
Why bio-based fertilisers?
• Closing nutrient cycles
• Safe recovery from nutrient-rich side-streams
• Bioavailability and agronomic efficency
• Best technologies for site specific management
• Soil improvement and threat mitigation
