At De Zeeuwse Stromen in Renesse, Green Key Gold shapes the way we power hot showers, light rooms, reduce waste, and source products—without compromising comfort.

What is Green Key Gold?

Green Key is the largest sustainability hallmark for the tourism and recreation industry in the Netherlands, held by almost 700 companies—from hotels to zoos and bungalow parks. Green Key Gold is its highest level for hotels and congress locations.

• The label confirms we do more for sustainability than the law requires, while preserving guest comfort and quality.
• Green Key is internationally recognized and aligns with the United Nations Sustainable Development Goals (2015–2030).

How Green Key Gold improves your stay—practically

Sustainability should feel effortless. Here’s what you can expect during your visit.

Energy you can feel (and not see)

• Solar hot water at scale: On our hotel roof, we operate 40 solar thermal panels feeding a 4 × 1,000-litre hot-water buffer. This system reduces our gas use by about 50,000–60,000 m3 annually, taking advantage of Zeeland’s abundant sunshine.
• Smart, efficient operations: We use LED lighting, light sensors, smart thermostats, high-efficiency boilers, and insulation to cut energy use without reducing comfort.
• Keycard-controlled lighting: In guest rooms, lights are activated by your keycard—a simple, intuitive way to avoid leaving power on unnecessarily.
• No minibars in rooms: Removing energy-intensive minibars is a conscious choice that saves power across the property.

Waste becomes a resource

• On-site biodigester: Your vegetable, fruit, and food leftovers are converted into renewable biogas and high-quality plant food. That biogas helps heat our hotel rooms and shared areas—a circular solution you contribute to simply by dining with us.
• Separation from plastic to coffee grounds: Across the property we separate waste streams, giving materials a better second life.

Water and cleaning with care

• Water-saving measures: Showers, taps, and operational practices are tuned to reduce water use while maintaining a comfortable experience.
• Responsible housekeeping: We use ecological cleaning products with precise dosing, and our bathroom soap and shampoo carry ECO labels.
• Towel reuse: If your towels are still clean, simply leave them on the rack and we’ll skip a wash—saving water and energy.

Local and social choices

• Local purchasing where possible: We prioritize sustainable, local sourcing in our purchasing. For example, at our nearby beach pavilion De Haven van Renesse (less than 300 meters from the hotel), lunches and dinners are prepared with fresh products from the region.
• Community and conservation: We stimulate local activities in cultural heritage, social, nature, and environmental fields; we also contribute through sponsorships and work structurally with ASeal in Stellendam.

Accessibility and inclusion

• Accessible by design: We are very accessible for disabled guests. The hotel features wide passages, a lift serving all hotel rooms, and one fully wheelchair-friendly room with a lowered bed and adapted bathroom. Please note: only the wellness changing rooms are less accessible by wheelchair.

Why Green Key Gold matters (and how it’s verified)

Green Key Gold sets a stringent bar across energy, water, waste, purchasing, and guest experience. Certification requires meeting the international standards of the Green Key organization and demonstrating continuous improvement. For guests, that translates into a stay where comfort, quality, and responsibility go hand in hand.

From a practical perspective:

• Solar thermal and smart building systems reduce fossil fuel use without affecting your comfort.
• Biodigestion and waste separation decrease landfill impact and create renewable energy.
• Responsible purchasing supports local producers and reduces transport footprint.
• Housekeeping choices protect water quality and indoor air while keeping rooms fresh and welcoming.

Your role: simple ways to help (and enjoy)

Small actions make a big difference—especially when multiplied across many stays.

1. Use the keycard holder to power the room only when you’re inside.
2. Hang towels you’ll reuse; place used ones on the floor for replacement.
3. Sort waste where provided so materials can be recycled or repurposed.
4. Shower mindfully—shorter showers save water and energy.
5. Explore locally—walk the dunes, cycle the island, and dine on regional products. Start with Explore Schouwen-Duiveland by bike.
