Green Key


Hotel Ernst Sillem Hoeve has always been engaged in CSR. In recent years, interest in CSR, environment and durability has increased in trade and industry. More and more companies receive a hallmark like, for example, a Green Key. We proudly announce to be in the possesion of the Golden Green Key; with this we meet the highest standards of the hallmark and belong to the top of the tested companies in the Netherlands. With this Golden Green Key we wish to show our guests that durable entrepreneurship plays a central role in our organisation.

Ernst Sillem Hoeve's profits go to the YMCA. The YMCA is Ernst Sillem Hoeve's sole shareholder. The money is spent on youth work, holidays for children with multiple handicaps or behavioural problems and on holidays for children of refugees. These holidays are supported by 300 young volunteers who are equipped by the YMCA to make these holidays possible.

Furthermore, support is given to projects in Indonesia (renovation of an elementary school in Surabaya) and Armenia (leadership training for summercamps).

Separate waste collection and cleaning

  • We use microfiber cloths when cleaning the hotelrooms and public spaces.
  • We use dispencers in the bathrooms, toilets and staffrooms. We use environmentally friendly supplies.
  • Instructions for reusing towels in the hotelrooms.
  • We have separate underground containers for paper, glass and residual waste. This makes the gathering and storage more efficient as there are less waste collections. Furthermore, due to cooler temperatures underground preventing nasty smells from spreading easily, it is also more hygenic. 
  • We also collect cartridges separately and there will be recycling bins for the organic waste from the kitchen.
