A new project – VARGA(Water Resource Recovery Facility) – aims to transform the traditional treatment plant Avedøre WWTP (350,000 PE) into a Water Resource Recovery Facility, by implementing several innovative technologies within wastewater treatment, nutrient recovery and greenhouse gas reduction. Major elements in the project include pre-filtration in full scale, P recovery in pilot scale and active reduction of N2O.

As part of the project, a Life Cycle Assessment and an eco-efficiency analysis has been conducted. Initial results show that the Total Added Value is higher after implementing the VARGA concept compared to business as usual – without compromising the treatment efficiency.

Circular economy is central for the project and the experiences gained further contribute to the Danish national goal of an energy and climate neutral water sector in 2030 as well as the UN agenda on sustainable development.

The VARGA project is in fully compliance with BIOFOS´ strategy 2020-2025.

This strategy fully integrates seven of the UN Sustainable Development Goals with SDG’: 6, 7, 11, 12, 13, 14 and 17.
