WISAG, one of Germany's leading multi-service companies, is entering a technology partnership with Phlair, a Munich-based Direct Air Capture company, and is supporting Phlair’s lighthouse project for the permanent storage of unavoidable CO₂ emissions. With this step, WISAG positions itself as an innovative, technology-open company that engages early and proactively with relevant future technologies.
Direct Air Capture (DAC) plays a central role in removing residual emissions that cannot be reduced or avoided even in the long term. The Intergovernmental Panel on Climate Change (IPCC) estimates that around 10 gigatons (billion tons) of CO₂ must be removed from the atmosphere annually by 2050 to meet the 1.5°C target of the Paris Agreement. In service-intensive industries in particular, a portion of emissions is difficult to avoid entirely. This is exactly where Direct Air Capture comes in as a Carbon Dioxide Removal (CDR) technology.
The flagship project supported by WISAG is Phlair’s first larger DAC demonstration plant in Germany. It operates using a multi-stage process to capture CO₂ from ambient air. Through this technology partnership, which begins in 2027, WISAG aims to build future technological expertise and gain experience in working with innovative solutions. Phlair will announce detailed information about the project at the end of the year.

How Phlair's process works, step by step:
1. Pull in air and capture CO₂
Fans draw ambient air through an alkaline liquid that chemically binds the CO₂. The remaining air flows out clean.
2. Release the CO₂
The bound CO₂ is added to an acid, which releases the CO₂ again at very high purity.
3. Recover acid and base
This is where Phlair's core innovation, the hydrolyzer, comes in. Using electricity (instead of heat), it regenerates acid and base from the spent solutions for the previous steps, keeping the cycle closed.
4. Use or store the CO₂
The pure CO₂ is captured and either stored permanently (for thousands to millions of years), e.g. underground or in demolition concrete, or reused as a feedstock, e.g. for carbon-neutral fuel.
Project is part of WISAG's holistic sustainability strategy
By participating in the lighthouse project, WISAG underscores its commitment to a future worth living: sustainability is anchored as the first of four pillars in its Vision 2030 and is actively advanced through the company's holistic sustainability strategy.
Among other goals, the values-driven family business aims to reduce its Scope 1 and Scope 2 emissions by 90 percent by 2030 compared to the 2022 baseline. Following the principle of "avoidance and reduction before offsetting", WISAG is taking a range of measures to get there.
These include operating three company-owned wind turbines and currently four photovoltaic plants, through which its own energy supply company currently produces more green electricity (2025: approx. 27.6 GWh) than its German branches consume. WISAG uses more than a third of this electricity itself, while surplus power is fed into the public grid.
In addition, the company is gradually electrifying its vehicle fleet by 2030 (excluding special-purpose vehicles for which no market alternative is available by then).
Emissions that cannot be avoided or reduced by 2030 are currently offset through certified climate protection projects.

Building technological competence as a strategic focus
By deliberately building technology competence through its participation in Phlair's lighthouse project, WISAG ensures it can evaluate potential solutions for offsetting unavoidable CO₂ emissions early and carefully – while continuing to push ahead with measures to reduce its Scope 1 and Scope 2 emissions.
Michael C. Wisser, CEO of the WISAG Group
"What makes the project with Phlair particularly interesting for us is that it sits at the intersection of ecological transformation and technological progress.
It fully supports our holistic sustainability strategy, through which we, as a values-driven family business, want to contribute to a future worth living for current and future generations.
Our goal is to gain both key economic and technological insights into how to deal sensibly with unavoidable CO₂ emissions through our participation in the project and our close collaboration with Phlair."
For Phlair, the partnership is a signal that companies from the service sector, too, are ready to establish technological CO₂ removal as a potentially permanent part of their emissions strategy.

"Put simply, CDR is a form of waste disposal. The fact that a multi-service company like WISAG, whose roots are in facility cleaning, is now starting to permanently and innovatively address its own emissions through DAC is more than just a nice analogy. It shows that an owner-managed company that thinks and acts long-term is already laying the foundation for a successful emissions strategy. And doing so, by gaining a deep understanding of the technology first instead of relying on certificates alone."
