Sustainability Sustainability Initiatives

On the path to a 100% sustainable wellness experience

A more stress-free world – with a 100% sustainable wellness experience.

Renewable energy

Recharge and regain new energy our guests do it every day in our thermen. And now, nearly 900 solar panels have been installed on the roof of each resort. Thanks to this investment, we generate enough green energy to power all our saunas entirely with self-generated electricity.

The next step in sustainability is building our own energy buffers, allowing us to manage energy more intelligently. With these, we store surplus wind and solar energy and use it exactly when we need it.

A balance of warmth and cold

Warm and cold two essential elements at the heart of our thermen. Not only during your day of relaxation, but also behind the scenes, we continuously regulate flows of heat and cold. We do this through a system called thermal energy storage (TES), a sustainable initiative that allows us to heat and cool our resort efficiently.

How does it work? Simple: on warm days, we extract ‘cold’ from the storage system to cool, for example, our floors and spaces. On colder days, we reverse the process and use the stored heat released during cooling to warm our spaces.

Heat recovery systems

Another system we use is heat recovery. This system captures heat from areas such as our swimming pools, showers, and kitchens filters out odours and reuses it to heat our resort. Through floor cooling, we extract excess warmth from our saunas.

And that very heat is reused to warm the floors of our sauna square. A smart (and for you, comfortable) way to save energy!

Sustainable food and drinks

More vegetarian options, organic products, locally sourced ingredients and dishes, fairtrade coffee and tea, and collaborations with local entrepreneurs at Thermen Resorts, we focus on food and drinks that not only taste good but are also better for the planet.

We strongly believe in reducing food waste. That’s why we use our own biodigester.

This system processes all leftover food from our restaurants into biogas and plant-based fertiliser. The fertiliser is used in our gardens, and the biogas powers our dryers and cooking appliances. In fact, our dryers run 100% on biogas.
