Transforming urine into fertiliser

How it works

Circular sanitation. Sustainable events

Our mobile system upcycles urine into fertiliser. We integrate seamlessly with your toilet infrastructure, creating a safe, sustainable product right there on site.

No chemicals. No waste. No lorry miles. This is circular sanitation.

Together, we can transform waste into a resource

Our mobile urine recovery system is designed for festivals, sporting events, and temporary sites. We can connect with your existing sanitation set-up with our hassle free, modular solution.

  • a visible, science-based solution to waste
  • Lower the carbon footprint of waste disposal
  • Produce a sustainable fertiliser instead of generating waste
  • Support sustainability goals and the circular economy
  • Landowners can receive a sustainable fertiliser made directly from on-site resources
