At EnviDan, we are proud that we will once again have the opportunity to use our specialist competencies in wastewater, when we, together with BIOFOS, will be in charge of the lighthouse project VARGA, which has been granted just over DKK 19 million. DKK in grants from the Ministry of the Environment and Food under the MUDP program.
The main purpose of the project is to transform a traditional treatment plant into a Water & Resource Recycling Plant, thus aiming to ensure that the resources in wastewater and waste are utilized even better than today.
The project develops essential parts of the circular economy with a focus on achieving CO2 neutrality as well as the utilization of the nutrients in urban waste and wastewater for the production of organic food. The project thus demonstrates synergies through collaboration on the utilization of resources across the water, waste and the organic agricultural sector.
The project has a total budget of just over DKK 84 million. The lighthouse project started in January 2017 and is expected to be completed in mid-2020.
The road to the treatment plant of the future
The conventional treatment plant must be rethought as a resource plant that both purifies wastewater and makes full use of resources. This will be demonstrated at one of Denmark’s largest treatment plants Avedøre (capacity of approx. 400,000 PE) which will constitute a case for demonstration of Danish environmental technology in an international context.
Dines Thornberg, Development Manager at BIOFOS, says: “We must change the whole way of thinking, so that in future we think of a treatment plant as a resource plant. The project provides a unique opportunity for Denmark to emerge as a pioneering country, where we both purify water and utilize the resources in the wastewater. ”
BIOFOS, EnviDan, ARC, UNISENSE and DTU Miljø are the partners who in collaboration will find new methods for achieving CO2 neutrality and resource utilization in VARGA. “We see great export prospects in the Lighthouse project VARGA within our consultancy services such as CO2-neutral purification, circular economy, upgrade of biogas, advanced online management and deliveries of Salsnes filters for optimizing carbon harvesting and concentrating primary sludge,” says development manager at EnviDan A / S, Jeanette Agertved Madsen.
EnviDan is a full service environmental company offering professional solutions within the drinking water, wastewater, biogas and environment.

Every day of the year we relieve the inhabitants and companies of the five capital municipalities Dragør, Frederiksberg, Hvidovre, Copenhagen and Tårnby of their waste and supply heat and electricity to their households in return. In total this amounts to 435,000 tons of waste which is converted into electricity and
Unisense Environment has developed the world's only N2O (nitrous oxide) Wastewater Sensor for direct measurement in wastewater treatment processes. Nitrous oxide is a strong green house gas 300 times more potent than CO2 and emissions from N2O can account for as much as 90% of total carbon footprint from wastewater treatment. The N2O Wastewater System from Unisense Environment enables real-time and on-site quantification of dissolved N2O and emission from wastewater treatment processes. New state-of-the-art bioprocess and emission mitigation controls can be developed using N2O sensor input yielding a clear environmental advantage over standard control regimes. Unisense Environment was established in 2014 by a team of university scientists with more than 20 years of experience in developing, constructing, and applying microsensors primarily in environmental research. We have in-house development and production, and a strong outreach in international collaborations.
