Responsibility and sustainability

at mainhaus Stadthotel Frankfurt

Our actions 
The entire mainhaus Stadthotel team works with a lot of creativity and passion to continuously find and implement sustainable corporate goals. This naturally includes the fact that we:
✓ avoid waste wherever possible
✓ provide certified, sustainable natural cosmetics (ECO by Green Culture) in the hotel rooms
✓ use ecologically degradable cleaning and washing products
✓ only change bed linen and towels during your stay if requested
✓ use water-saving buttons
✓ only use recycled paper with the EU Ecolabel and FSC label
✓ continue to reduce paper consumption by digitizing our documents
✓ offer rental bicycles (by prior arrangement)
✓ use green electricity and also have our own CHP (combined heat and power plant) for energy production

Biodiversity: our mainhaus bees
as of April 2020 we have had our own mainhaus bees – initially there were two beehives with two bee colonies. Last year a third beehive was added so that we could harvest around 50 kg of honey, which we use in our kitchen, offer on the breakfast buffet or sell here in the hotel. A great beekeeper looks after the well-being of our hard-working employees throughout the year. 

Biodiversity: Insect hotel
We have built an insect hotel in our own garden to provide safe nesting places and safe wintering options for insects. Our little “hotel” has an additional positive effect in that it contributes to the propagation of our plants in the garden and thus supports natural planting.

Climate protection: Planting trees
We are doing our part to combat climate change and have planted a total of 100 trees together with our sister hotel in a reforestation project in Lasel in the Eifel.

Regional, organic, good: the restaurant
At our extensive breakfast buffet we offer fair trade coffee specialties from GEPA, organic teas from ChariTea, organic egg dishes, our own mainhaus honey, rolls and bread specialties from Kröger’s Brötchen directly from Frankfurt, a variety of vegetarian and vegan dishes as well as various milk alternatives and organic juices.
To counteract food waste, we focus on a small but fine selection of dishes in the à la carte restaurant. We source our food mainly from regional suppliers and farmers.
We also work with Too Good To Go to reduce the climate-damaging waste caused by overproducing food.
At our breakfast we completely avoid individual packaging – except for crispbread. 

GreenSign Hotel Certification 
On July 27, 2023, we had a sustainability certification carried out by the GreenSign Institute and are proud to have completed it with a conformity level of 82%. However, sustainability is an ongoing process that is not completed with the certificate alone. 

Carbon footprint
For 2022, we had the GreenSign Institute, in collaboration with myclimate, determine our CO2 emissions per overnight stay: the good result of 15 kg per overnight stay shows that we are on the right track with our actions. The aim is, of course, to continue to reduce this value in order to bring the greenhouse gas emissions generated by our company to a necessary minimum.

Sustainable gifts for guests
Since this year, we have been supported in the production of our gifts by Caritas Wertarbeit at the Gut Fronhof site (Cologne). First, our bee-friendly wildflower mix was prepared. Next came a delicious organic salad herb mix.Around 30 people have a completely normal working day there. The employees of Caritas Wertarbeit at Gut Fronhof are given work to do a job that is suitable for them, as unfortunately they could not be placed on the general job market. The next project is already in the works and more sustainable, beautiful farewell gifts for our hotel guests will follow.
