VCS Denmark is ready to assist companies on their path toward a green transition
VCS Denmark are empowering the green transition by collaborating with other companies to create innovative, sustainable solutions. Headquartered in Odense, VCS Denmark combines local strengths with global ambitions for a greener future.
Research facilities in Odense to promote a green transition
Though primarily focused on wastewater treatment, VCS Denmark in Odense has developed advanced facilities that go beyond this mission, supporting the biosolutions sector and promoting the green transition both local and international.
At the HQ in Odense, VCS Denmark offers facilities for researchers and businesses, creating a collaborative environment for companies to partner and develop new sustainable solutions. Their focus is to lead in sustainable projects and share knowledge and insights with others. This vision aims to attract companies to Odense to work towards a greener future and establish partnerships that may bring further investment.
“VCS Denmark’s approach to collaboration and innovation is incredible. In Odense and, Denmark we constantly see new companies and new biosolutions emerging, which is beneficial for both growth and the environment. But the industry needs access to facilities and infrastructure to test and develop their products. VCS Denmark has those facilities, and the collaborations we’ve seen between the water utility and various companies clearly demonstrate how public-private partnerships are the right approach. This ensures innovative new solutions for the VCS Denmark’s core tasks and supports innovative companies in creating and scaling their businesses.”
Estech transforms greenhouse gases into green hydrogen
One of the latest examples of collaboration is between VCS Denmark and the company Estech.
Through this partnership, Estech tested its technology at the facilities in Odense, where they constructed a nearly full-scale setup. This arrangement provided ideal conditions for Estech to develop and refine its solution, giving them the time and resources needed to create a technology with the potential to position themselves as a leading provider of green solutions.
With the insights gained from this collaboration, Estech has now opened its own facility, becoming the first company in the world to both capture and utilize CO₂ in this way. By combining CO₂ capture with electrolysis, they can produce clean hydrogen from waste products, marking a groundbreaking advancement in sustainable technology.

Sludge is sustainably heat-treated with Aquagreen
Another collaboration is with the company Aquagreen.
Aquagreen collaborates with VCS Denmark on various fronts to share knowledge and leverage each other’s resources in advancing sustainable development. The water center has also supported the company in applying for funding assistance.
Aquagreen is taking a more sustainable approach to managing residual sludge left after biogas production. Instead of opting for incineration, Aquagreen’s process involves drying the water out of the sludge and then processing it through a low-oxygen pyrolysis unit. This sustainable heat treatment breaks down most environmental pollutants, leaving treated sludge that can be repurposed as fertilizer. After treatment, only about 10% of the original pollutants remain, representing a significant improvement over traditional incineration methods.
“At VCS Denmark we have several reasons to prioritize these collaborations. Of course, our main purpose is to provide high-quality drinking water and wastewater treatment for our citizens. But in my opinion, we are also obligated to innovate, develop and adapt new solutions to be able to handle our purpose in the best possible way. We can’t do that without involving companies and trends in the sector”.

Local strength and global ambitions
On VCS Denmark’s path toward future biosolutions, they are open to closer collaboration with industry networks, such as Odense’s thriving robotics cluster and the Food & Bio cluster. This collaboration also focuses on local strengths, which are an important asset for the company. Both Estech and Aquagreen have garnered international interest if they achieve their visions, but the local visions are just as essential for the future biosolutions at VCS Denmark and Odense.
