The opportunity
Empowering a sustainable tomorrow
Surplus slurry and manure carry nutrients, carbon and recoverable value, but too often become a storage, spreading and water-quality pressure for farms.
Onunda has developed patented, next-generation technology to turn wet organic surplus into useful products: biochar, nutrient-rich fertiliser and carbon-removal value.
Built in response to environmental concerns and growing nutrient pressure in agriculture, our technology helps reduce the risk of pathogens, harmful contaminants and excess nutrients reaching land and water.
The result is practical value for farms, useful products for growers, cleaner waterways, healthier soils, reduced reliance on imported fertilisers and a more circular future for British farming.

How it works
Transforming wastewater for a better world
Onunda offers a unique sewage and organic waste treatment solution combining hydrothermal carbonisation and gasification technologies. Our innovative approach maximises nutrient and energy recovery, serving as an alternative method for treating primary and secondary sludge or managing domestic, food and agricultural wastes. Onunda technology eliminates the need to return contaminated biosolids to land, effectively destroying harmful microplastics and forever chemicals in a robust and environmentally friendly way.
Maximising extraction of value, nutrients and energy.
