The new company Utilizero is a partnership between Aarhus Vand and DHI. It has been established to help utilities reduce carbon emissions and energy usage at wastewater treatment facilities from the solid experiences and solutions for automated process management, we have here in Denmark.

At traditional wastewater treatment plants, the energy produced is nowhere near enough to cover the operation of the plant. In Aarhus it is. Marselisborg WWTP has an energy self-sufficient far above 100 percent and the plant is in fact a power station, a bio refinery where energy is produced from wastewater.

Total energy renovation of the treatment plant at Egaa, just outside Aarhus, means that Aarhus Vand is setting new standards for developing treatment plants from energy guzzlers into energy producers.

At Aaby and Marselisborg Wastewater Treatment Plants we have extracted phosphorus from the wastewater. Over a decade this has been sold as a valuable fertiliser under the name PhosphorCare.
