Onunda is a Cumbrian environmental technology company developing new ways to turn wet organic waste into useful resources.

Its patented process can convert surplus manure, slurry and digestate into biochar and nutrient-rich liquid fertiliser. The system can also recover energy during treatment, helping to make better use of waste materials.

The company originally focused on sewage sludge treatment. Today, it works mainly with agricultural residues, while also exploring further uses in wastewater treatment.

Onunda brings together expertise in engineering, water and energy. Its aim is to recover valuable materials, support British agriculture and improve the way surplus nutrients are managed.
