House & Furnishings
Sustainability is evident in many areas of our daily hotel operations, from the technical equipment and rooms to the catering and wellness facilities.
LED lights: Our hotel is equipped with modern LED lights and motion detectors in the hallways. This reduces energy consumption during hotel operations and combines efficiency with pleasant lighting.
Electricity from renewable energy sources: We source electricity for the hotel from renewable energy sources, as specified by our energy supplier. This is part of our approach to reducing energy-related emissions.
Conscious cosmetics & care: Our rooms are equipped with a high-quality, refillable toiletry set from the Valentina & Philippa brand, allowing us to consistently avoid plastic waste. In the spa area, we use certified natural cosmetics from PHARMOS Natur, which meets the NCS (Natural Cosmetics Standard) standards. This seal is awarded by the Society for Applied Business Ethics.
Cleaning with micro-dry steam technology: For cleaning, we rely on micro-dry steam devices from Medeco Cleantec. This allows us to reduce the use of traditional cleaning agents in daily hotel operations and, in many areas, to completely eliminate the need for additional cleaning chemicals.
E-mobility: We offer two on-site electric vehicle charging stations for our guests with electric vehicles.
Accessibility : We take accessibility into account in the design of our building and the accessibility of central areas.
Waste separation and food recycling: We place great importance on consistent waste separation and responsible food handling. In the kitchen, we collaborate with the Refood initiative to make good use of unused food.
Water with responsibility: In our bathrooms and public areas, we use modern pressure regulators that efficiently control the water flow. This allows us to save water without compromising the comfort of our guests.
Freshness from the herb garden: Head chef Daniel Bruder passionately tends our own herb garden. He harvests aromatic herbs directly on site for the exquisite dishes in the castle restaurant – ensuring fresh ingredients and short delivery routes within the hotel.
For nature
We are committed to preserving and promoting biodiversity in our immediate surroundings through selected projects.
Our tree planting campaign
Since the beginning of 2023, we have been working together with the GreenSign Institute on tree planting campaigns for reforestation in the Derenburg municipal forest. The goal is to plant approximately 10.000 trees annually.
Everything for humanity
At the castle hotel, we understand sustainability not only as an ecological and economic task, but also as a social responsibility.
Continuing education : Regular training of our employees on sustainability topics is particularly important to us. An internal Green Team develops and supports sustainability measures and facilitates internal discussions on these topics.
A space for artists: Since November 2023, we have opened our doors to talented artists from the region, who are invited to present their work in our historic setting. This initiative is part of our commitment to the local community and creates space for regional art and culture. We also ensure that key areas are accessible to people with and without disabilities. You can find an overview of the artists here.

Conscious enjoyment
In our restaurant, we focus on conscious enjoyment and concrete measures to reduce packaging and waste. You can find out here which steps we implement in our daily operations.
Our own beehives
Directly behind the castle hotel, we have established our own beehives in cooperation with an experienced beekeeper. The location, in close proximity to the baroque gardens, the castle park, and adjacent green spaces, offers the bees a diverse range of food sources.
Our own honey complements our culinary offerings. The beehives are part of selected measures we are implementing to support natural habitats in the immediate vicinity of the hotel.
