POWERSTEP demonstrated energy-positive sewage treatment concepts; RecaP addresses phosphorus capture and recycling from wastewater streams.
KRUEGER A/S
Danish water and wastewater engineering firm contributing full-scale treatment plant expertise to EU nutrient recovery and water quality research.
Their core work
Krüger A/S is a Danish water and wastewater engineering company specializing in the design, construction, and optimization of treatment plants and water infrastructure. In H2020 projects, they contribute industrial-scale expertise in sewage treatment, drinking water purification, and nutrient recovery — bridging the gap between lab research and full-scale plant operations. Their involvement typically brings real-world engineering know-how and access to operational treatment facilities for demonstration and validation purposes.
What they specialise in
NaToxAq focused on natural toxins in drinking water from source to tap.
RecaP (2021-2025) targets phosphorus capture, recycling, and environmental management — their most recent and directly funded project.
How they've shifted over time
Krüger's H2020 trajectory shows a progression from energy-focused wastewater treatment (POWERSTEP, 2015) through drinking water safety (NaToxAq, 2017) to circular economy nutrient recovery (RecaP, 2021). Their early involvement centred on demonstrating energy-positive sewage plants, while their most recent work zeroes in on phosphorus as a critical resource — reflecting the broader European shift toward circular water management. Notably, RecaP is the only project where they received direct EC funding, suggesting a move from peripheral third-party roles toward more substantive participation.
Krüger is shifting from conventional wastewater engineering toward circular economy applications — specifically nutrient recovery — making them a relevant partner for resource-from-waste research initiatives.
How they like to work
Krüger has never coordinated an H2020 project, participating instead as a third party (2 projects) or partner/participant (1 each). This is typical for an industrial engineering firm that provides facilities, operational data, or demonstration capacity rather than leading research agendas. With 43 unique partners across 12 countries, they connect broadly but lightly — useful as a validation or demonstration partner rather than a consortium architect.
Despite only three projects, Krüger has touched 43 unique partners across 12 countries, reflecting the large consortium sizes typical of MSCA and Innovation Action projects. Their network spans Northern and Western Europe with no obvious geographic concentration beyond their Danish base.
What sets them apart
Krüger brings something many research consortia lack: access to full-scale, operational water and wastewater treatment infrastructure in Denmark. For projects that need to move beyond lab-scale — demonstrating technologies at real treatment plants — an industrial partner like Krüger is essential. Their parent company ties to the broader Veolia group may also provide pathways to wider European deployment.
Highlights from their portfolio
- RecaPTheir only directly funded H2020 project (EUR 297,522), focused on the high-priority topic of phosphorus recovery — a critical raw material for European food security.
- POWERSTEPFull-scale demonstration of energy-positive sewage treatment, directly aligned with Krüger's core business of wastewater plant engineering.
