A new perspective on transforming infrastructure for the future
The benefits
Globally, wastewater treatment plants face challenges in managing biosolids produced from traditional biological treatment processes.
The stressed infrastructure faces increased pressures from immediate climate change impacts, causing record rainwater events that directly affect system capacity.
The sewerage network collects raw sewage waste, transferring it to treatment plants for processing. Clean water is then discharged into waterways, and the majority of remaining biosolids are then discharged to land for agriculture applications.
In recent years, heightened storm overflows and urbanisation have led to an increase in sewage discharged into waterways causing significant ecological impacts from excess nutrients.
There are also concerns about microplastics, heavy metals, PFAS, and endocrine disrupting chemicals found in biosolids, entering our food chain via landbanks and overflow discharges, posing risk to human health.
Amidst growing political, media, and public pressure, Onunda provides an innovative solution for treating biosolids waste. It maximises nutrient and energy recovery and minimises environmental impact in promotion of the circular economy.
Our vision
Our vision is to transform sewage sludge from a problem requiring expensive treatment and disposal into a valuable source of clean energy and nutrients with minimal environmental impact.
Our mission
Our mission is to deploy our advanced waste treatment solution worldwide, either as a stand-alone plant or retrofitted to existing waste water treatment facilities, offering customers improved environmental performance and cost savings. We are keen to develop new partnerships with existing players across the industry as we bring our technology to market through either traditional equipment sales/delivery contracts, new and more innovative build own operate models or alternatively as a licensing solution.
How Onunda can address the current challenges
Capacity for the future
Challenge
An outdated sewage treatment infrastructure is causing our natural environment to become contaminated.
Solution
Onunda technology provides additional capacity to wastewater networks to boost existing treatment capabilities.
Land and water contamination
Challenge
Using biosolid fertilisers in agriculture is introducing microplastics and persistent chemicals to the land, and storm overflows are contaminating freshwater habitats with raw sewage.
Solution
Onunda technology extracts and recovers nutrients and destroys the harmful micropollutants to help maintain the health and beauty of our natural environment.
Nutrient neutrality
Challenge
Population growth and treatment capacity constraints are leading to the accumulation of excess nutrients, including nitrates and phosphates, in natural catchment areas.
Solution
Onunda technology extracts and recovers these valuable nutrients, expanding treatment capacity to align with urbanization and population growth.
Zero carbon
Challenge
Our global dependence on burning fossil fuels for energy is accelerating climate change and leading to a loss of biodiversity within ecosystems.
Solution
Onunda technology operates without burning new fossil fuels. It extracts the energy needed to power the plant, and surplus energy from the sewage sludge feedstock.
